Basilar artery occlusive disease in stroke survivors in a multiethnic population

Objectives: To describe clinical, radiological findings, and outcome in a multiethnic population of stroke survivors with basilar artery occlusive disease (BAOC). Methods: Forty patients with infarcts in the basilar artery (BA) territory, alive 30 days after the ictus, participated in the study. BA stenosis (>50%) or occlusion was shown by magnetic resonance or digital subtraction angiography in all patients. Demographical, clinical and radiological characteristics were described. Modified Rankin Scale (MRS) scores at 30 days and 6 months after the ischemic event were evaluated. Association between demographical, clinical, radiological features and outcome were analyzed with Chi-square and Fisher`s exact tests. MRS scores at 30 days and 6 months were compared with the Wilcoxon test. Results: Sixty percent of the patients were men, and 33% were Afro-Brazilian. Mean age was 55.8 +/- 12.9 years. Most (90%) had multiple vascular risk factors. Stroke was preceded by TIA in 48% of the patients, and 80% had a history of arterial hypertension. The most common neurological symptom was vertigo/dizziness (60%) and the sign, hemiparesis (60%). Most of the infarcts were located in the pons (85%) and the BA middle third was the most frequently affected segment (33%). BA occlusion occurred in 58% of the patients. More severe vascular occlusive lesions were present in Whites (p = 0.002) and in patients with involvement of the middle third of the BA (p = 0.021). Large-artery atherosclerosis was the most common stroke etiology (88%) and was more frequent in older patients (p < 0.001). Most patients were treated with anticoagulation. MRS scores improved significantly at 6 months (p < 0.001): at this time, 78% of the patients had MRS scores between 0 and 2. Conclusions: We observed different results compared with other series: greater proportion of Afro-descendents, higher frequency of atherosclerosis and BA occlusion. Rates of preceding TIAs and good outcome at 6 months were similar to previously published data. These results represent a step forward towards understanding BAOC in a multiethnic context.

Pro- and Anti-inflammatory Cytokines in Steatosis and Steatohepatitis

Fatty liver disease is a problem in both bariatric patients and in patients with moderate obesity. Tumor necrosis factor (TNF)-alpha has been frequently measured in nonalcoholic steatohepatitis (NASH) with or without diabetes, but less is known about interleukin (IL)-6 and IL-10. Moderately obese patients (n = 80) with histologically proven steatosis (n = 29) and NASH (n = 51) were recruited. Serum levels of cytokines were documented along with clinical information. The aim was to identify the correlates of such biomolecules in a stable population. Diabetes tended to be more associated with NASH (52.5% instead of 41.4%, P = 0.015), with no difference of age, gender, or body mass index regarding steatosis. For the entire population, cytokine changes were not significant, including TNF-alpha and IL-6. In diabetics only, all markers tended to diminish with NASH, especially IL-10 (P = 0.000). IL-10 correlated with homeostatic model assessment index (P = 0.000) and other variables of glucose homeostasis in diabetes, thus representing a major marker of the disease. (1) Generally inconsistent changes in pro- and anti-inflammatory cytokines occurred when NASH was globally compared to steatosis. (2) In contrast, downregulation of IL-6 and IL-10 was perceived in diabetics with NASH. (3) Arterial hypertension did not play a role in these circumstances. (4) IL-10 maintained strong correlations with glucose metabolism indices. (5) TNF-alpha could not be incriminated for progressive liver damage, as values failed to increase in NASH. (6) Investigations of IL-10 and other counterregulatory cytokines are lacking in this context and deserve further studies.

Incidence of stroke subtypes, prognosis and prevalence of risk factors in Joinville, Brazil: a 2 year community based study

Background: There have been few population based studies on stroke risk factors and prognosis conducted in Brazil. The objective of this study was to evaluate, over a 2 year period, the incidence of the subtypes of first ever stroke, the prevalence of cardiovascular risk factors and functional prognosis in a city located in the south of Brazil. Methods: The period from January 2005 to December 2006 was evaluated prospectively by compiling data on first ever stroke cases, medications used prior to the morbidity and the incidence of traditional risk factors. The annual incidence was adjusted for age using the direct method. Patients were monitored for at least 6 months following the event. Results: Of 1323 stroke cases, 759 were first ever stroke cases. Of these, 610 were classified as infarctions, 94 as intracerebral haemorrhage and 55 as subarachnoid haemorrhage. The crude incidence rate per 100 000 inhabitants was 61.8 for infarction (95% CI 57.0 to 66.9), 9.5 for intracerebral haemorrhage (95% CI 7.7 to 11.6) and 5.6 for subarachnoid haemorrhage (95% CI 4.2 to 7.3). The 30 day case fatality was 19.1%. The most prevalent cardiovascular risk factor was arterial hypertension. By post-stroke month 6, 25% had died (95% CI 21.4 to 29.1) whereas 61.5% had regained their independence (95% CI 56.2 to 68.3). Conclusions: Case fatality rate, prognosis and incidence adjusted for stroke subtypes were similar to those found in other population based studies. The prevalence rates of ischaemic heart disease, dyslipidaemia, arterial hypertension and diabetes suggest that Joinville presents a mixed pattern of cardiovascular risk, a pattern seen in developed and developing countries alike.

Mucosal leishmaniasis: description of case management approaches and analysis of risk factors for treatment failure in a cohort of 140 patients in Brazil

Background Mucosal leishmaniasis is caused mainly by Leishmania braziliensis and it occurs months or years after cutaneous lesions. This progressive disease destroys cartilages and osseous structures from face, pharynx and larynx. Objective and methods The aim of this study was to analyse the significance of clinical and epidemiological findings, diagnosis and treatment with the outcome and recurrence of mucosal leishmaniasis through binary logistic regression model from 140 patients with mucosal leishmaniasis from a Brazilian centre. Results The median age of patients was 57.5 and systemic arterial hypertension was the most prevalent secondary disease found in patients with mucosal leishmaniasis (43%). Diabetes, chronic nephropathy and viral hepatitis, allergy and coagulopathy were found in less than 10% of patients. Human immunodeficiency virus (HIV) infection was found in 7 of 140 patients (5%). Rhinorrhea (47%) and epistaxis (75%) were the most common symptoms. N-methyl-glucamine showed a cure rate of 91% and recurrence of 22%. Pentamidine showed a similar rate of cure (91%) and recurrence (25%). Fifteen patients received itraconazole with a cure rate of 73% and recurrence of 18%. Amphotericin B was the drug used in 30 patients with 82% of response with a recurrence rate of 7%. The binary logistic regression analysis demonstrated that systemic arterial hypertension and HIV infection were associated with failure of the treatment (P < 0.05). Conclusion The current first-line mucosal leishmaniasis therapy shows an adequate cure but later recurrence. HIV infection and systemic arterial hypertension should be investigated before start the treatment of mucosal leishmaniasis.

Time course of haemodynamic, respiratory and inflammatory disturbances induced by experimental acute pulmonary polystyrene microembolism

Background and objective The time course of cardiopulmonary alterations after pulmonary embolism has not been clearly demonstrated and nor has the role of systemic inflammation on the pathogenesis of the disease. This study aimed to evaluate over 12 h the effects of pulmonary embolism caused by polystyrene microspheres on the haemodynamics, lung mechanics and gas exchange and on interleukin-6 production. Methods Ten large white pigs (weight 35-42 kg) had arterial and pulmonary catheters inserted and pulmonary embolism was induced in five pigs by injection of polystyrene microspheres (diameter similar to 300 mu mol l(-1)) until a value of pulmonary mean arterial pressure of twice the baseline was obtained. Five other animals received only saline. Haemodynamic and respiratory data and pressure-volume curves of the respiratory system were collected. A bronchoscopy was performed before and 12 h after embolism, when the animals were euthanized. Results The embolism group developed hypoxaemia that was not corrected with high oxygen fractions, as well as higher values of dead space, airway resistance and lower respiratory compliance levels. Acute haemodynamic alterations included pulmonary arterial hypertension with preserved systemic arterial pressure and cardiac index. These derangements persisted until the end of the experiments. The plasma interleukin-6 concentrations were similar in both groups; however, an increase in core temperature and a nonsignificant higher concentration of bronchoalveolar lavage proteins were found in the embolism group. Conclusion Acute pulmonary embolism induced by polystyrene microspheres in pigs produces a 12-h lasting hypoxaemia and a high dead space associated with high airway resistance and low compliance. There were no plasma systemic markers of inflammation, but a higher central temperature and a trend towards higher bronchoalveolar lavage proteins were found.

Cardiopulmonary Manifestations of Hepatosplenic Schistosomiasis

Background -Schistosomiasis is a highly prevalent disease with >200 million infected people. Pulmonary hypertension is one of the pulmonary manifestations in this disease, particularly in its hepatosplenic presentation. The aim of this study was to determine the prevalence of pulmonary hypertension in schistosomiasis patients with the hepatosplenic form of the disease. Methods and Results -All patients with hepatosplenic schistosomiasis followed up at the gastroenterology department of our university hospital underwent echocardiographic evaluation to search for pulmonary hypertension. Patients presenting with systolic pulmonary artery pressure >40 mm Hg were further evaluated through right heart catheterization. Our study showed an 18.5% prevalence of patients with elevated systolic pulmonary artery pressure at echocardiography. Invasive hemodynamics confirmed the presence of pulmonary hypertension in 7.7% (95% confidence interval, 3.3 to 16.7) of patients, with a prevalence of precapillary (arterial) pulmonary hypertension of 4.6% (95% confidence interval, 1.5 to 12.7). Conclusions -Our study reinforces the role of echocardiography as a screening tool in the investigation of pulmonary hypertension, together with the need for invasive monitoring for a proper diagnosis. We conclude that hepatosplenic schistosomiasis may account for one of the most prevalent forms of pulmonary hypertension worldwide, justifying the development of further studies to evaluate the effect of specific pulmonary hypertension treatment in this particular form of the disease.

Novel Mutations in CYP11B1 Gene Leading to 11 beta-Hydroxylase Deficiency in Brazilian Patients

Background: Deficiency of 11 beta-hydroxylase results in the impairment of the last step of cortisol synthesis. In females, the phenotype of this disorder includes different degrees of genital ambiguity and arterial hypertension. Mutations in the CYP11B1 gene are responsible for this disease. Objective: The objective of the study was to screen the CYP11B1 gene for mutations in two unrelated Brazilian females with congenital adrenal hyperplasia due to 11 beta-hydroxylase deficiency. Design: The coding and intron-exon junction regions of CYP11B1 were totally sequenced. A putative splice mutation was further investigated by minigene transcription. Results: We report two novel CYP11B1 mutations in these Brazilian patients. An Arabian Lebanese descendent female was found to be homozygous for a cytosine insertion at the beginning of exon 8, changing the 404 arginine to proline. It alters the open reading frame, creating a putative truncated protein at 421 residue, which eliminates the domain necessary for the association of heme prosthetic group. A severely virilized female was homozygous for the g. 2791G>A transition in the last position of exon 4. This nucleotide is also part of 5` intron 4 donor splice site consensus sequence. Minigene experiments demonstrated that g. 2791G>A activated an alternative splice site within exon 4, leading to a 45-bp deletion in the transcript. The putative translation of such modified mRNA indicates a truncated protein at residue 280. Conclusions: We describe two novel mutations, g. 4671_4672insC and g. 2791G>A, that drastically affects normal protein structure. These mutations abolish normal enzyme activity, leading to a severe phenotype of congenital adrenal hyperplasia due to 11 beta-hydroxylase deficiency. (J Clin Endocrinol Metab 94: 3481-3485, 2009)

Obstructive Sleep Apnea Is Frequent in Patients with Hypertensive Intracerebral Hemorrhage and Is Related to Perihematoma Edema

Background: Obstructive sleep apnea (OSA) is related to increased systemic inflammation and arterial hypertension. We hypothesize that OSA is frequent in patients with acute hypertensive intracerebral hemorrhage (ICH) and is related to the perihematoma edema. Methods: Thirty-two non-comatose patients with a hypertensive ICH underwent polysomnography in the acute phase. Perihematoma edema volume was measured on CT scans at admission, after 24 h (early control) and after 4-5 days (late control). The Spearman coefficient (r(s)) was used for correlations. Results: OSA occurred in 19 (59.4%) patients. The apnea-hypopnea index was correlated with relative edema at admission CT (r(s) = 0.40; p = 0.031), early CT (r(s) = 0.46; p = 0.011) and at late CT (r(s) = 0.59; p = 0.006). Conclusions: OSA is highly frequent during the acute phase of hypertensive ICH and is related to perihematoma edema. Copyright (C) 2009 S. Karger AG, Basel

Uridine adenosine tetraphosphate-induced contraction is increased in renal but not pulmonary arteries from DOCA-salt hypertensive rats

Matsumoto T, Tostes RC, Webb RC. Uridine adenosine tetraphosphate-induced contraction is increased in renal but not pulmonary arteries from DOCA-salt hypertensive rats. Am J Physiol Heart Circ Physiol 301: H409-H417, 2011. First published May 6, 2011; doi:10.1152/ajpheart.00084.2011.-Uridine adenosine tetraphosphate (Up(4)A) was reported as a novel endothelium-derived contracting factor. Up(4)A contains both purine and pyrimidine moieties, which activate purinergic (P2)X and P2Y receptors. However, alterations in the vasoconstrictor responses to Up(4)A in hypertensive states remain unclear. The present study examined the effects of Up(4)A on contraction of isolated renal arteries (RA) and pulmonary arteries (PA) from DOCA-salt rats using isometric tension recording. RA from DOCA-salt rats exhibited increased contraction to Up(4)A versus arteries from control uninephrectomized rats in the absence and presence of N(G)-nitro-L-arginine (nitric oxide synthase inhibitor). On the other hand, the Up(4)A-induced contraction in PA was similar between the two groups. Up(4)A-induced contraction was inhibited by suramin (nonselective P2 antagonist) but not by diinosine pentaphosphate pentasodium salt hydrate (Ip5I; P2X(1) antagonist) in RA from both groups. Furthermore, 2-thiouridine 5`-triphosphate tetrasodium salt (2-Thio-UTP; P2Y(2) agonist)-, uridine-5`-(gamma-thio)-triphosphate trisodium salt (UTP gamma S; P2Y(2)/P2Y(4) agonist)-, and 5-iodouridine-5`-O-diphosphate trisodium salt (MRS 2693; P2Y(6) agonist)-induced contractions were all increased in RA from DOCA-salt rats. Protein expression of P2Y(2)-, P2Y(4)-, and P2Y(6) receptors in RA was similar between the two groups. In DOCA-salt RA, the enhanced Up(4)A-induced contraction was reduced by PD98059, an ERK pathway inhibitor, and Up(4)Astimulated ERK activation was increased. These data are the first to indicate that Up(4)A-induced contraction is enhanced in RA from DOCA-salt rats. Enhanced P2Y receptor signaling and activation of the ERK pathway together represent a likely mechanism mediating the enhanced Up(4)A-induced contraction. Up(4)A might be of relevance in the pathophysiology of vascular tone regulation and renal dysfunction in arterial hypertension.

Hemodynamic responses to aortic depressor nerve stimulation in conscious L-NAME-induced hypertensive rats

Durand MT, Castania JA, Fazan R Jr, Salgado MC, Salgado HC. Hemodynamic responses to aortic depressor nerve stimulation in conscious L-NAME-induced hypertensive rats. Am J Physiol Regul Integr Comp Physiol 300: R418-R427, 2011. First published November 24, 2010; doi: 10.1152/ajpregu.00463.2010.-The present study investigated whether baroreflex control of autonomic function is impaired when there is a deficiency in NO production and the role of adrenergic and cholinergic mechanisms in mediating reflex responses. Electrical stimulation of the aortic depressor nerve in conscious normotensive and nitro-L-arginine methyl ester (L-NAME)-induced hypertensive rats was applied before and after administration of methylatropine, atenolol, and prazosin alone or in combination. The hypotensive response to progressive electrical stimulation (5 to 90 Hz) was greater in hypertensive (-27 +/- 2 to -64 +/- 3 mmHg) than in normotensive rats (-17 +/- 1 to -46 +/- 2 mmHg), whereas the bradycardic response was similar in both groups (-34 +/- 5 to -92 +/- 9 and -21 +/- 2 to -79 +/- 7 beats/min, respectively). Methylatropine and atenolol showed no effect in the hypotensive response in either group. Methylatropine blunted the bradycardic response in both groups, whereas atenolol attenuated only in hypertensive rats. Prazosin blunted the hypotensive response in both normotensive (43%) and hypertensive rats (53%) but did not affect the bradycardic response in either group. Prazosin plus angiotensin II, used to restore basal arterial pressure, provided hemodynamic responses similar to those of prazosin alone. The triple pharmacological blockade abolished the bradycardic response in both groups but displayed similar residual hypotensive response in hypertensive (-13 +/- 2 to -27 +/- 2 mmHg) and normotensive rats (-10 +/- 1 to -25 +/- 3 mmHg). In conclusion, electrical stimulation produced a well-preserved baroreflex-mediated decrease in arterial pressure and heart rate in conscious L-NAME-induced hypertensive rats. Moreover, withdrawal of the sympathetic drive played a role in the reflex bradycardia only in hypertensive rats. The residual fall in pressure after the triple pharmacological blockade suggests the involvement of a vasodilatory mechanism unrelated to NO or deactivation of alpha(1)-adrenergic receptor.

Sympathetic activity is not increased in L-NAME hypertensive rats

Santos FM, Dias DPM, Silva CAA, Fazan Jr R, Salgado HC. Sympathetic activity is not increased in L-NAME hypertensive rats. Am J Physiol Regul Integr Comp Physiol 298: R89-R95, 2010. First published November 4, 2009; doi:10.1152/ajpregu.00449.2009.-The role played by the sympathetic drive in the development of N(G)-nitro-L-arginine methyl ester (L-NAME)-induced hypertension is not firmly established. Therefore, the present study was undertaken in conscious rats in which hypertension was induced by treatment with L-NAME over the course of either 2 or 14 days. Mean arterial pressure (MAP) was measured via a catheter placed in the femoral artery, drugs were administered via a cannula placed in the femoral vein, and renal sympathetic nerve activity (RSNA) was monitored using an implanted electrode. Despite the remarkable increase in arterial pressure, heart rate did not change after treatment with L-NAME. RSNA was similar in L-NAME-induced hypertensive rats treated over the course of 2 or 14 days, as well as in normotensive rats. It was also demonstrated that L-NAME-induced hypertensive rats displayed a resetting of the baroreflex control of RSNA to hypertensive levels, with decreased sensitivity over the course of 2 or 14 days. Furthermore, the sympathetic-vagal balance examined in the time and frequency domain and the renal and plasma norepinephrine content did not differ between groups. In conclusion, the evaluation of the sympathetic drive in conscious rats demonstrated that the arterial hypertension induced by L-NAME treatment over the course of 2 and 14 days does not show sympathetic overactivity.

Low-dose transdermal hormone therapy does not interfere with the blood pressure of hypertensive menopausal women: a pilot study

Objectives To determine the effects of low-dose transdermal hormone therapy (HT) on systolic (SBP) and diastolic (DBP) blood pressure (BP) evaluated by 24-h ambulatory blood pressure monitoring (ABPM) in hypertensive postmenopausal women. Methods The study was conducted on 24 hypertensive postmenopausal women aged, on average, 54 years and under treatment with enalapril maleate (10-20 mg/day) combined or not with hydrochlorothiazide (25 mg/day). Thirteen women used a transdermal adhesive containing estradiol and norethisterone (25 and 125 mu g active substance/day, respectively) and 11 did not receive HT. ABPM, lipid profile, and climacteric symptoms were evaluated before and 3 and 6 months after treatment. Results After 3 and 6 months of follow-up, there was a statistically significant reduction of the Blatt-Kupperman menopausal index in the treated group (19.6 +/- 8.3 vs. 9.6 +/- 5.9 vs. 9.7 +/- 7.0; P=0.01). No significant difference in any of the ABPM variables (areas under the systolic and diastolic curves, mean SBP and DBP, SBP and DBP loads and wakefulness-sleep variation) or in the lipid profile was observed between or within groups at the three time points studied. Conclusion Low-dose transdermal HT administered for 6 months was effective in improving climacteric symptoms and did not change BP values or circadian pattern in postmenopausal women with mild-to-moderate arterial hypertension taking antihypertensive medications.

Protective effects of carvedilol on systemic vascular damage induced by angiotensin II: Organ-specific effects independent of antihypertensive effects

Background: The protective effect of carvedilol on multiple organ damage induced by angiotensin II (Ang II) remains unclear. The aim of this study was to evaluate the protective effect of carvedilol on the heart, liver, and kidney in rats infused with Ang II. Material/Methods: Wistar rats were randomly distributed into three groups: control (no treatment), continuously infused with Ang II (150 eta g/min for 72 hr), and treated with Ang II + carvedilol (90 mg/kg/d). Histological sections of the myocardium, kidney, and liver were analyzed for the presence of necrosis. Results: Ang II induced arterial hypertension which was not affected by carvedilol treatment (tail-cuff blood pressures, control: 125 +/- 13.6, Ang II: 163 +/- 27.3, Ang II + CV: 178 +/- 39.8 mmHg, p<0.05). Also, there were perivascular inflammation and necrosis in the myocardium, kidney, and hepatocytes necrosis around the terminal vein. Carvedilol treatment fully prevented damage to the heart and kidney and attenuated liver lesions induced by the Ang II infusion. Conclusions: The protective effect of carvedilol on perivascular damage induced by Ang II infusion depended on the target organ. The prevention of heart damage occurred independently of the antihypertensive effects of carvedilol.

Evaluation of albuminuria and its relationship with blood pressure in dogs with chronic kidney disease

Background Microalbuminuria and hypertension have long been associated with a guarded prognosis in human patients with a variety of diseases. In veterinary medicine, tests for microalbuminuria have been used for detecting early kidney damage, but there is little information regarding its association with high blood pressure in dogs with chronic kidney disease (CKD). Objective The objective of this study was to evaluate albuminuria and its association with arterial hypertension in dogs with CKD. Methods Urinary albumin:creatinine (UAC) ratio, urinary protein:creatinine (UPC) ratio, and systolic blood pressure were determined in 39 clinically healthy dogs and 40 dogs with CKD. Results UAC in dogs with CKD (range, 0.002-7.99; median, 0.38) was statistically different from that of control dogs (range, 0.0005-0.01; median, 0.002). Microalbuminuria (UAC 0.03-0.3) and macroalbuminuria (UAC > 0.3) were detected in 32.5% and 50% of dogs with CKD, respectively. Sixty percent (24/40) of dogs with CKD had systolic pressure >= 180 mmHg; in these dogs, UAC ratio (range, 0.006-7.99; median, 1.72) was significantly higher than in dogs with CKD and systolic pressure < 180 mmHg (range, 0.002-4.83; median, 0.10). Of hypertensive dogs with CKD, those with UPC > 1.0 usually had macroalbuminuria, those with UPC 0.5-1.0 usually had microalbuminuria, and those with UPC < 0.5 usually lacked albuminuria. Conclusions UAC ratio was higher in hypertensive than in normotensive dogs with CKD. Tests designed to detect microalbuminuria may be useful for hypertensive dogs with CKD and a UPC < 1.0 to detect the onset and magnitude of albuminuria. Once macroalbuminuria is overt, the UPC ratio itself can be used for the same purpose.

Myocardial abnormalities in hypertensive patients with normal and abnormal left ventricular filling: a study of ultrasound tissue characterization and strain

Abnormal left ventricular (LV) filling is common, but not universal, in hypertensive LV hypertrophy (LVH). We sought to elucidate the relative contributions of myocardial structural changes, loading and hypertrophy to LV dysfunction in 113 patients: 85 with hypertensive LVH and 28 controls without LVH and with normal filling. Patients with normal dobutamine stress echocardiography and no history of coronary artery disease were selected, in order to exclude a contribution from ischaemia or scar. Abnormal LV filling was identified in 65 LVH patients, based on Doppler measurement of transmitral filling and annular velocities. All patients underwent grey-scale and colour tissue Doppler imaging from three apical views, which were stored and analysed off line. Integrated backscatter (113) and strain rate imaging were used to detect changes in structure and function; average cyclic variation of 113, strain rate and peak systolic strain were calculated by averaging each segment. Calibrated 113 intensity, corrected for pericardial 113 intensity, was measured in the septum and posterior wall from the parasternal long-axis view. Patients with LVH differed significantly from controls with respect to all backscatter and strain parameters, irrespective of the presence or absence of abnormal LV filling. LVH patients with and without abnormal LV filling differed with regard to age, LV mass and incidence of diabetes mellitus, but also showed significant differences in cyclic variation (P < 0.01), calibrated 113 in the posterior wall (P < 0.05) and strain rate (P < 0.01), although blood pressure, heart rate and LV systolic function were similar. Multivariate logistic regression analysis demonstrated that age, LV mass index and calibrated IB in the posterior wall were independent determinants of abnormal LV filling in patients with LVH. Thus structural and functional abnormalities can be detected in hypertensive patients with LVH with and without abnormal LV filling. In addition to age and LVH, structural (not functional) abnormalities are likely to contribute to abnormal LV filling, and may be an early sign of LV damage. 113 is useful for the detection of myocardial abnormalities in patients with hypertensive LVH.
