Hypertensive nephropathy treatment by heart-protecting musk pill: a study of anti-inflammatory therapy for target organ damage of hypertension.

This study was designed to investigate the protective effect of the heart-protecting musk pill (HMP) on inflammatory injury of kidney from spontaneously hypertensive rat (SHR). Male SHRs aged 4 weeks were divided into SHR model group, HMP low-dosage group (13.5 mg/kg), and HMP high-dosage group (40 mg/kg). Age-matched Wistar-Kyoto rats were used as normal control. All rats were killed at 12 weeks of age. Tail-cuff method and enzyme-linked immunosorbent assay were used to determine rat systolic blood pressure and angiotensin II (Ang II) contents, respectively. Renal inflammatory damage was evaluated by the following parameters: protein expressions of inflammatory cytokines, carbonyl protein contents, nitrite concentration, infiltration of monocytes/macrophages in interstitium and glomeruli, kidney pathological changes, and excretion rate of urinary protein. HMP did not prevent the development of hypertension in SHR. However, this Chinese medicinal compound decreased renal Ang II content. Consistent with the change of renal Ang II, all the parameters of renal inflammatory injury were significantly decreased by HMP. This study indicates that HMP is a potent suppressor of renal inflammatory damage in SHR, which may serve as a basis for the advanced preventive and therapeutic investigation of HMP in hypertensive nephropathy.

Safety, tolerability, and efficacy of fixed combination therapy with dorzolamide hydrochloride 2% and timolol maleate 0.5% in glaucoma and ocular hypertension.

Glaucoma is a collection of diseases characterized by multifactorial progressive changes leading to visual field loss and optic neuropathy most frequently due to elevated intraocular pressure (IOP). The goal of treatment is the lowering of the IOP to prevent additional optic nerve damage. Treatment usually begins with topical pharmacological agents as monotherapy, progresses to combination therapy with agents from up to 4 different classes of IOP-lowering medications, and then proceeds to laser or incisional surgical modalities for refractory cases. The fixed combination therapy with the carbonic anhydrase inhibitor dorzolamide hydrochloride 2% and the beta blocker timolol maleate 0.5% is now available in a generic formulation for the treatment of patients who have not responded sufficiently to monotherapy with beta adrenergic blockers. In pre- and postmarketing clinical studies, the fixed combination dorzolamide-timolol has been shown to be safe and efficacious, and well tolerated by patients. The fixed combination dorzolamide-timolol is convenient for patients, reduces their dosing regimen with the goal of increasing their compliance, reduces the effects of "washout" when instilling multiple drops, and reduces the preservative burden by reducing the number of drops administered per day.

Patient compliance during drug therapy for hypertension

A retrospective study has been conducted examining the relationship between patient compliance and race among diagnosed hypertensives in NHANES II 1976-1980. The study includes the review/analysis of 403 blacks and 2,011 nonblacks. Patient compliance was measured using the frequency that patients took their hypertensive medication.^ A statistically significant trend of increasing compliance as age increased was found (p =.000) in blacks, nonblacks, and the study group. The number of times a person spoke with a doctor about high blood pressure was found to be statistically significant (p ==.000) in nonblacks and the study group. ^

Cultural beliefs and hypertension in rural Philippines

Hypertension (HTN), the major risk factor for cardiovascular disease (CVD), is emerging as a major public health problem in the Philippines. CVD has been the leading cause of mortality in the Philippines since 1990. ^ Although research has shown that certain populations have a greater propensity for HTN, and that culture may be a factor, empirical investigations of the influence of cultural beliefs on HTN are lacking. ^ The operational aims of this study were to: (a) develop and examine the reliability (test-retest, internal consistency) and validity (content) of a questionnaire which measures factors related to HTN; (b) administer the questionnaire; and (c) measure blood pressure, height, and weight of the ≥ 30 year old residents of San Antonio, Nueva Ecija, Philippines. ^ The analytic aims were to determine the: (a) cultural beliefs relating to HTN; (b) associations between cultural beliefs and HTN; and (c) extent to which cultural beliefs versus biological, behavioral, socioeconomic, and access factors are associated with HTN. ^ A cluster survey was conducted among 336 residents ≥ 30 years old in May, 1998. Sixty clusters of households were derived using probability proportionate to size sampling technique. Seven households per cluster were visited and one respondent per household was randomly chosen for interview and measurement of blood pressure, height and weight. A response rate of 84% (336/400) was achieved. ^ Results showed that the test-retest reliability of cultural belief items was 0.69–0.96. Internal consistency reliability was 0.74. ^ HTN (SBP ≥ 140; or DBP ≥ 90 mmHg; or currently taking anti-hypertensive medication) prevalence was 23/100. Univariate logistic regression showed cultural beliefs to be significantly associated (p < 0.037) with HTN. However, multivariate analysis showed that only age ≥ 50 (p = 0.000), family history of HTN (p = 0.004) and body mass index ≥ 25 (p = 0.003) were significant predictors. ^ In the absence of fully implemented programs to prevent and control HTN, the current prevalence is only expected to increase, leading to substantial increases in morbidity and mortality and health care cost. It is recommended that research which focuses on designing, implementing, and evaluating culturally appropriate community-wide programs on HTN prevention and control be undertaken in this community. ^

Hypertension control and related variables among urban and rural adults in Taiwan

Literature on hypertension treatment has demonstrated that a healthy life style is one of the best strategies for hypertension control. In exploring the mechanisms of behavioral change for hypertension control, a comprehensive study based on the Transtheoretical Model was carried out in Taiwan during the summer of 2000 with a sample of 350 hypertensive adults living in Taipei urban and rural areas. ^ The relationships among stages of change, processes of change and demographic factors were analyzed for six health behaviors—low fat food consumption, alcohol use, smoking, physical activity, weight control, and routine blood pressure checkups. In addition, differences were assessed between urban and rural populations in changing their behavior for hypertension control. ^ The results showed that rural populations had more difficulties than urban populations in avoiding smoking and engaging in physical activity, and the processes of change being used by urban populations were significantly greater than rural populations. The study findings support a strong association between processes and stages of change. ^ Individuals who use more processes of change will be more inclined to move from precontemplation stage to maintenance stage. Counterconditioning, which is the substitution of alternatives for the problem behaviors, in this study, significantly helped people to change diet, engage in physical activity, and check blood pressure regularly. For example, counterconditioning is eating more vegetables instead of meat, or engaging in physical activity as a time to relax rather than another task to accomplish. ^ In addition, self-reevaluation was the most important process for helping people to engage in physical activity; and social liberation was the most important process for changing diet behavior. The findings in this study may be applied to improve health behaviors among rural populations with low income and low education; however, at the same time, the obesity problems among urban populations should be prevented to control hypertension in Taiwan. ^

Genetic mechanisms of Na+, K+-ATPase regulation in hypertension

The spontaneously hypertensive rat (SHR) is a model of essential hypertension. During the early development of hypertension, the SHR demonstrates increased proximal tubule (PT) Na+ reabsorption. I hypothesized that the increased PT Na+ reabsorption exhibited by the young SHR was due to altered sub-cellular distribution of Na+, K +-ATPase compared to the normotensive Wistar Kyoto (WKY). The hypothesis is supported, herein, by observations of greater Na+, K +-ATPase α 1 abundance in PT plasma membrane and lower abundance in late endosomes of 4wk SHR despite no difference in total PT α 1 abundance. There is a greater amount of Ser-18 unphosphorylated α 1 in the 4wk SHR PT. Total PT Na+, K+-ATPase γ abundance is greater in SHR at 4wk and 16wk but γ abundance in plasma membrane is greater only at 4wk. The phosphatase, calcineurin, was chosen for study because it is involved in the stimulation of Na+, K +-ATPase. No difference in calcineurin coding sequence, expression, or activity was observed in SHR. Gene expression arrays were next used to find candidate genes involved in the regulation of Na+, K +-ATPase. The first candidate analyzed was soluble epoxide hydrolase (sEH). The gene encoding sEH (EPHX2) showed lower expression in SHR. There was also a reduction in sEH protein abundance but there was no correlation between protein abundance and blood pressure in F2 progeny. Two EPHX2 alleles were identified, an ancestral allele and a variant allele containing four polymorphisms. sEH activity was greater in animals carrying the variant allele but the inheritance of the variant allele did not correlate with blood pressure. Gene expression arrays also led to the examination of genes involved in redox balance/Na+, K+-ATPase regulation. A pattern of lower expression of genes involved in reactive radical detoxification in SHR was discerned. Six transcription factor binding sites were identified that occurred more often in these genes. Three transcription factors that bind to the HNF1 site were expressed at lower levels in SHR. This points to the HNF1 transcriptional complex as an important trans-acting regulator of a wide range of genes involved in altered redox balance in SHR. ^

Candidate gene identification following linkage: Search for hypertension susceptibility genes

Following up genetic linkage studies to identify the underlying susceptibility gene(s) for complex disease traits is an arduous yet biologically and clinically important task. Complex traits, such as hypertension, are considered polygenic with many genes influencing risk, each with small effects. Chromosome 2 has been consistently identified as a genomic region with genetic linkage evidence suggesting that one or more loci contribute to blood pressure levels and hypertension status. Using combined positional candidate gene methods, the Family Blood Pressure Program has concentrated efforts in investigating this region of chromosome 2 in an effort to identify underlying candidate hypertension susceptibility gene(s). Initial informatics efforts identified the boundaries of the region and the known genes within it. A total of 82 polymorphic sites in eight positional candidate genes were genotyped in a large hypothesis-generating sample consisting of 1640 African Americans, 1339 whites, and 1616 Mexican Americans. To adjust for multiple comparisons, resampling-based false discovery adjustment was applied, extending traditional resampling methods to sibship samples. Following this adjustment for multiple comparisons, SLC4A5, a sodium bicarbonate transporter, was identified as a primary candidate gene for hypertension. Polymorphisms in SLC4A5 were subsequently genotyped and analyzed for validation in two populations of African Americans (N = 461; N = 778) and two of whites (N = 550; N = 967). Again, SNPs within SLC4A5 were significantly associated with blood pressure levels and hypertension status. While not identifying a single causal DNA sequence variation that is significantly associated with blood pressure levels and hypertension status across all samples, the results further implicate SLC4A5 as a candidate hypertension susceptibility gene, validating previous evidence for one or more genes on chromosome 2 that influence hypertension related phenotypes in the population-at-large. The methodology and results reported provide a case study of one approach for following up the results of genetic linkage analyses to identify genes influencing complex traits. ^

Racial and ethnic disparities in diabetes mellitus and hypertension: Influence of income and insurance status in a cross-sectional study of the United States

Racial/ethnic disparities in diabetes mellitus (DM) and hypertension (HTN) have been observed and explained by socioeconomic status (education level, income level, etc.), screening, early diagnosis, treatment, prognostic factors, and adherence to treatment regimens. To the author's knowledge, there are no studies addressing disparities in hypertension and diabetes mellitus utilizing Hispanics as the reference racial/ethnic group and adjusting for sociodemographics and prognostic factors. This present study examined racial/ethnic disparities in HTN and DM and assessed whether this disparity is explained by sociodemographics. To assess these associations, the study utilized a cross-sectional design and examined the distribution of the covariates for racial/ethnic group differences, using the Pearson Chi Square statistic. The study focused on Non-Hispanic Blacks since this ethnic group is associated with the worst health outcomes. Logistic regression was used to estimate the prevalence odds ratio (POR) and to adjust for the confounding effects of the covariates. Results indicated that except for insurance coverage, there were statistically significant differences between Non-Hispanic Blacks and Non-Hispanic Whites, as well as Hispanics with respect to study covariates. In the unadjusted logistic regression model, there was a statistically significant increased prevalence of hypertension among Non-Hispanic Blacks compared to Hispanics, POR 1.36, 95% CI 1.02-1.80. Low income was statistically significantly associated with increased prevalence of hypertension, POR 0.38, 95% CI 0.32-0.46. Insurance coverage, though not statistically significant, was associated with an increase in the prevalence of hypertension, p>0.05. Concerning DM, Non-Hispanic Blacks were more likely to be diabetic, POR 1.10, 95% CI 0.85-1.47. High income was statistically significantly associated with decreased prevalence of DM, POR 0.47, 95% CI 0.39-0.57. After adjustment for the relevant covariates, the racial disparities between Hispanics and Non-Hispanic Blacks in HTN was removed, adjusted prevalence odds (APOR) 1.21, 95% CI 0.88-1.67. In this sample, there was racial/ethnic disparity in hypertension but not in diabetes mellitus between Hispanics and Non-Hispanic Blacks, with disparities in hypertension associated with socioeconomic status (family income, education, marital status) and also by alcohol, physical activity and age. However, race, education and BMI as class variables were statistically significantly associated with hypertension and diabetes mellitus p<0.0001. ^

Characterization of glucocorticoid receptor (NR3C1) gene polymorphisms and a family-based association study with hypertension

Hypertension is usually defined as having values of systolic blood pressure ≥140 mmHg, diastolic blood pressure ≥90 mmHg. Hypertension is one of the main adverse effects of glucocorticoid on the cardiovascular system. Glucocorticoids are essential hormones, secreted from adrenal glands in circadian fashion. Glucocorticoid's effect on blood pressure is conveyed by the glucocorticoid receptor (NR3C1), an omnipresent nuclear transcription factor. Although polymorphisms in this gene have long been implicated to be a causal factor for cardiovascular diseases such as hypertension, no study has yet thoroughly interrogated the gene's polymorphisms for their effect on blood pressure levels. Therefore, I have first resequenced ∼30 kb of the gene, encompassing all exons, promoter regions, 5'/3' UTRs as well as at least 1.5 kb of the gene's flanking regions from 114 chromosome 5 monosomic cell lines, comprised of three major American ethnic groups—European American, African American and Mexican American. I observed 115 polymorphisms and 14 common molecularly phased haplotypes. A subset of markers was chosen for genotyping study populations of GENOA (Genetic Epidemiology Network of Atherosclerosis; 1022 non-Hispanic whites, 1228 African Americans and 954 Mexican Americans). Since these study populations include sibships, the family-based association test was performed on 4 blood pressure-related quantitative variables—pulse, systolic blood pressure, diastolic blood pressure and mean arterial pressure. Using these analyses, multiple correlated SNPs are significantly protective against high systolic blood pressure in non-Hispanic whites, which includes rsb198, a SNP formerly associated with beneficial body compositions. Haplotype association analysis also supports this finding and all p-values remained significant after permutation tests. I therefore conclude that multiple correlated SNPs on the gene may confer protection against high blood pressure in non-Hispanic whites. ^

Factor H variant Y402H and the prevalence of hypertension and proteinuria: The Atherosclerosis Risk in Communities study

Hypertension is a significant risk factor for cardiovascular disease, which in turn is a major cause of morbidity and mortality worldwide. While the pathogenesis of vascular injury and subsequent end organ damage is complex, there is emerging data to support a role for the complement system in endovascular diseases. The complement Factor H Y402H polymorphism has been associated with a number of vasculopathies, including age-related macular degeneration (AMD), ischemic stroke and myocardial infarction. The current study evaluated the relationship of the Y402H polymorphism with hypertension and microalbuminuria in large the bi-racial Atherosclerosis Risk in Communities (ARIC) study. The Y402H polymorphism was found to be associated with a 48% (p-value 0.042) increase in the risk of developing incident hypertension in African American participants. No significant association was found with the Y402H polymorphism and microalbuminuria. The results from this investigation reveal the first association of the Factor H Y402H polymorphism and an increased risk of incident hypertension in African Americans. ^

Incident hypertension among pre-hypertensive adolescents: Evaluation of pre-hypertension as an independent risk factor among secondary school students in the Houston area

Cardiovascular disease has been the leading cause of death in the United States for over fifty years. While multiple risk factors for cardiovascular disease have been identified, hypertension is one of the most commonly recognized and treatable. Recent studies indicate that the prevalence of hypertension among children and adolescents is between 3-5%, much higher than originally estimated and likely rising due to the epidemic of obesity in the U.S. In 2004, the National High Blood Pressure Education Program Working Group on High Blood Pressure in Children and Adolescents published new guidelines for the diagnosis and treatment of hypertension in this population. Included in these recommendations was the creation of a new diagnosis, pre-hypertension, aimed at identifying children at-risk for hypertension to provide early lifestyle interventions in an effort to prevent its ultimate development. In order to determine the risk associated with pre-hypertension for the development of incident HTN, a secondary analysis of a repeated cross-sectional study measuring blood pressure in Houston area adolescents from 2000 to 2007 was performed. Of 1006 students participating in the blood pressure screening on more than one occasion not diagnosed with hypertension at initial encounter, eleven were later found to have hypertension providing an overall incident rate of 0.5% per year. Incidence rates were higher among overweight adolescents–1.9% per year [IRR 8.6 (1.97, 51.63)]; students “at-risk for hypertension” (pre-hypertensive or initial blood pressure in the hypertensive range but falling on subsequent measures)–1.4% per year [IRR 4.77 (1.21, 19.78)]; and those with blood pressure ≥90th percentile on three occasions–6.6% per year [IRR 21.87 (3.40, 112.40)]. Students with pre-hypertension as currently defined by the Task Force did have an increased rate of hypertension (1.1% per year) but it did not reach statistical significance [IRR 2.44 (0.42, 10.18)]. Further research is needed to determine the morbidity and mortality associated with pre-hypertension in this age group as well as the effectiveness of various interventions for preventing the development of hypertensive disease among these at-risk individuals. ^

Association of left ventricular hypertrophy and stage of hypertension by ambulatory blood pressure monitor

Hypertension in adults is defined by risk for cardiovascular morbidity and mortality, but in children, hypertension is defined using population norms. The diagnosis of hypertension in children and adolescents requires only casual blood pressure measurements, but the use of ambulatory blood pressure monitoring to further evaluate patients with elevated blood pressure has been recommended in the Fourth Report on the Diagnosis, Evaluation, and Treatment of High Blood Pressure in Children and Adolescents. The aim of this study is to assess the association between stage of hypertension (using both casual and 24 hour ambulatory blood pressure measurements) and target organ damage defined by left ventricular hypertrophy (LVH) in a sample of children and adolescents in Houston, TX. A retrospective analysis was performed on the primary de-identified data from the combination of participants in two, IRB approved, cross-sectional studies. The studies collected basic demographic data, height, weight, casual blood pressures, ambulatory blood pressures, and left ventricular measurements by echocardiography on children age 8 to 18 years old. Hypertension was defined and staged using the criteria for ambulatory blood pressure reported by Lurbe et al. [1] with some modification. Left ventricular hypertrophy was defined using left ventricular mass index (LVMI) criteria specific for children and adults. The pediatric criterion was LVMI2.7 > 95th percentile for gender and the adult criterion was LVMI2.7 > 51g/m2.7. Participants from the original studies were included in this analysis if they had complete demographic information, anthropometric measures, casual blood pressures, ambulatory blood pressures, and echocardiography data. There were 241 children and adolescents included: 19.1% were normotensive, 17.0% had white coat hypertension, 11.6% had masked hypertension, and 52.4% had confirmed hypertension. Of those with hypertension, 22.4% had stage 1 hypertension, 5.8% had stage 2 hypertension, and 24.1% had stage 3 hypertension. Participants with confirmed hypertension were more likely to have LVH by pediatric criterion than those who were normotensive [OR 2.19, 95% CI (1.04–4.63)]; LVH defined by adult criterion did not differ significantly in normotensives compared with hypertensives [OR 2.08, 95% CI (0.58–7.52)]. However, there was a significant trend in the increased prevalence of LVH across the six blood pressure categories for LVH defined by both pediatric and adult criteria (p < 0.001 and p = 0.02, respectively). Additionally, the mean LVM indexed by height 2.7 had a significantly increased trend across blood pressure stages from normal to stage 3 hypertension (p < 0.02). Pediatric hypertension is defined using population norms, and although children with mild hypertension are not at increased odds of having target organ damage defined by LVH, those with severe hypertension are more likely to have LVH. Staging hypertension by ambulatory blood pressure further describes an individual's risk for LVH target organ damage. ^

Hypertension and cognitive decline among patients of Alzheimer's disease

Objective. The main aim of our study is to assess the effect of hypertension on the decline in cognitive impairment among Alzheimer’s patients. Methods. We analyzed the data of AD patients enrolled in Baylor ADMDC in a prospective study design. We divided AD patients into two groups based on the definition of hypertension. We described a decline in cognitive impairment as a change of 5 points in mini-mental state examination score (MMSE) from the baseline visit. Results. Independent of covariates, AD patients with hypertension did not exhibit a significant decline in cognitive impairment after adjustment of covariates, age, race and education (Hazard Ratio (HR) = 1.07, p value 0.58, 95% confidence interval 0.84-1.39) than AD patients without hypertension. In addition, AD patients with hypertension did not experience decline in cognitive impairment sooner than AD patients without hypertension. (P value 0.83). Conclusions . Hypertension is not associated with cognitive impairment over time among patients with Alzheimer’s disease enrolled in Baylor ADMDC after other potential confounders were taken into account. These findings should not be interpreted as a basis for discouraging appropriate medical treatment of hypertension in AD patients. Greater efforts should be made to improve the recognition of hypertension as a modifiable risk factor for decline in cognitive impairment in AD population. ^

The association between mental health and hypertension in the 2005 Department of Defense Population Survey

Major objectives within Healthy People 2010 include improving hypertension and mental health management of the American population. Both mental health issues and hypertension exist in the military which may decrease the health status of military personnel and diminish the ability to complete assigned missions. Some cases may be incompatible with military service even with optimum treatment. In the interest of maintaining a fit fighting force, the Department of Defense regularly conducts a survey of health related behaviors among active duty military personnel. The 2005 DoD Survey was conducted to obtain information regarding health and behavioral readiness among active duty military personnel to assess progress toward selected Healthy People 2010 objectives. ^ This study is a cross-sectional prevalence design looking at the association of hypertension treatment with mental health issues (either treatment or perceived need for treatment) within the military population sampled in the 2005 DoD Survey. There were 16,946 military personnel in the final cross-sectional sample representing 1.3 million active duty service members. The question is whether there is a significant association between the self-reported occurrence of hypertension and the self-reported occurrence of mental health issues in the 2005 DoD Survey. In addition to these variables, this survey examined the contribution of various sociodemographic, occupational, and behavioral covariates. An analysis of the demographic composition of the study variables was followed by logistic analysis, comparing outcome variables with each of the independent variables. Following univariate regression analysis, multivariate regression was performed with adjustment (for those variables with an unadjusted alpha level less than or equal to 0.25). ^ All the mental health related indicators were associated with hypertension treatment. The same relationship was maintained after multivariate adjustment. The covariates remaining as significant (p < 0.05) in the final model included gender, age, race/ethnicity and obesity. There is a need to recognize and treat co-morbid medical diagnoses among mental health patients and to improve quality of life outcomes, whether in the military population or the general population. Optimum health of the individual can be facilitated through discovery of treatable cases, to minimize disruptions of military missions, and even allow for continued military service. ^

Metabolic syndrome and cardiovascular mortality among participants of the hypertension detection and follow-up program

Metabolic Syndrome (MetS) is a clustering of cardiovascular (CV) risk factors that includes obesity, dyslipidemia, hyperglycemia, and elevated blood pressure. Applying the criteria for MetS can serve as a clinically feasible tool for identifying patients at high risk for CV morbidity and mortality, particularly those who do not fall into traditional risk categories. The objective of this study was to examine the association between MetS and CV mortality among 10,940 American hypertensive adults, ages 30-69 years, participating in a large randomized controlled trial of hypertension treatment (HDFP 1973-1983). MetS was defined as the presence of hypertension and at least two of the following risk factors: obesity, dyslipidemia, or hyperglycemia. Of the 10,763 individuals with sufficient data available for analysis, 33.2% met criteria for MetS at baseline. The baseline prevalence of MetS was significantly higher among women (46%) than men (22%) and among non-blacks (37%) versus blacks (30%). All-cause and CV mortality was assessed for 10,763 individuals. Over a median follow-up of 7.8 years, 1,425 deaths were observed. Approximately 53% of these deaths were attributed to CV causes. Compared to individuals without MetS at baseline, those with MetS had higher rates of all-cause mortality (14.5% v. 12.6%) and CV mortality (8.2% versus 6.4%). The unadjusted risk of CV mortality among those with MetS was 1.31 (95% confidence interval [CI], 1.12-1.52) times that for those without MetS at baseline. After multiple adjustment for traditional risk factors of age, race, gender, history of cardiovascular disease (CVD), and smoking status, individuals with MetS, compared to those without MetS, were 1.42 (95% CI, 1.20-1.67) times more likely to die of CV causes. Of the individual components of MetS, hyperglycemia/diabetes conferred the strongest risk of CV mortality (OR 1.73; 95% CI, 1.39-2.15). Results of the present study suggest MetS defined as the presence of hypertension and 2 additional cardiometabolic risk factors (obesity, dyslipidemia, or hyperglycemia/diabetes) can be used with some success to predict CV mortality in middle-aged hypertensive adults. Ongoing and future prospective studies are vital to examine the association between MetS and cardiovascular morbidity and mortality in select high-risk subpopulations, and to continue evaluating the public health impact of aggressive, targeted screening, prevention, and treatment efforts to prevent future cardiovascular disability and death.^
