Impacto do padrão geométrico ventricular na remodelação cardíaca após o infarto do miocárdio

BACKGROUND: The relevance of left ventricular (LV) geometric pattern after myocardial infarction is not known. OBJECTIVES: To analyze the presence of different LV geometric patterns and teir impact as a predictor of remodeling in patients with myocardial infarction. METHODS: Patients with anterior acute myocardial infarction (n = 80) were divided according to the geometric pattern: normal (normal left ventricular mass index [LVMI] and normal relative wall thickness [RWT]), concentric remodeling (normal LVMI and increased RWT), concentric hypertrophy (increased LVMI and RWT) and eccentric hypertrophy (increased LVMI and normal RWT). After six months, echocardiographic assessment was repeated. RESULTS: Four patients died. Of the survivors, 41 showed remodeling (R +), whereas 39 did not (R-). Considering the geometric pattern, the cases were distributed as follows: 24 patients with normal pattern, 13 with concentric remodeling, 29 with concentric hypertrophy and 14 with eccentric hypertrophy. Patients who showed remodeling had larger infarction sizes analyzed by peak CPK (R + = 4,610 (1,688-7,970), R- = 1,442 (775-4247), p <0.001) and CK-MB (R + = 441 (246 - 666), R- = 183 (101-465), p <0.001), trend towards higher prevalence of concentric remodeling (R+ = 10, R- = 3, p = 0.08) and lower prevalence of eccentric hypertrophy (R + = 2 R- = 12, p = 0.006). In the multivariate regression analysis, infarction size was a predictor (OR = 1.01, p = 0.020) and eccentric hypertrophy was a protective factor (OR = 0.189, p = 0.046) of ventricular remodeling after coronary occlusion. CONCLUSION: The LV geometric pattern of can have an impact on the remodeling process in patients with myocardial infarction.

Efeitos de drogas antiplaquetárias na doença periodontal

The association between platelets, angiogenesis and progression or repair of periodontal disease has been little explored and, consequently, the results are inconclusive. The pathogenic bacteria present in the periodontal pocket release endotoxins that affect the endothelial integrity and are able to induce the production of chemical mediators derived from plasma proteins and blood clotting while altering platelet function. There is great interest in the modulation of platelet activity in vascular disorders, especially cardiovascular diseases. For this reason, antiplatelet drugs, that are commonly used in the prevention of thromboembolic diseases, such as myocardial infarction, ischemic stroke and peripheral arterial disease, have been used. Aspirin is the only non-steroidal antiinflammatory agent with antiplatelet activity. In the periodontium, instead of only reduces levels of inflammatory cytokines, also significantly affects bleeding on probing, suggesting a dose-dependent modulation of periodontitis. In contrast, clopidogrel and ticlopidine are thienopyridine drugs with no known antiinflammatory action, suggesting that this benefit is related to an antiinflammatory effect indirectly correlated to their antiplatelet activity already established. In the literature there is limited information about the effect of these drugs on periodontium and periodontal disease development. Antiplatelet drugs hypothetically can change both the pathogenesis of periodontitis and subsequent periodontal tissue repair by blocking the secretion of chemical mediators which in general are important in modulating inflammation and tissue repair.

Frequency and clinical predictors of coronary artery disease in chronic renal failure renal transplant candidates

Background/aims: Cardiovascular diseases are major causes of mortality in chronic renal failure patients before and after renal transplantation. Among them, coronary disease presents a particular risk; however, risk predictors have been used to diagnose coronary heart disease. This study evaluated the frequency and importance of clinical predictors of coronary artery disease in chronic renal failure patients undergoing dialysis who were renal transplant candidates, and assessed a previously developed scoring system. Methods: Coronary angiographies conducted between March 2008 and April 2013 from 99 candidates for renal transplantation from two transplant centers in Sao Paulo state were analyzed for associations between significant coronary artery diseases (>= 70% stenosis in one or more epicardial coronary arteries or >= 50% in the left main coronary artery) and clinical parameters. Results: Univariate logistic regression analysis identified diabetes, angina, and/or previous infarction, clinical peripheral arterial disease and dyslipidemia as predictors of coronary artery disease. Multiple logistic regression analysis identified only diabetes and angina and/or previous infarction as independent predictors. Conclusion: The results corroborate previous studies demonstrating the importance of these factors when selecting patients for coronary angiography in clinical pretransplant evaluation.

Assistência cirúrgico-odontológica a pacientes com história de infarto do miocárdio

The execution of a appropriate odontological surgical treatment for patients with Myocardial Infarction has been based in established protocols for important works in world wide literature during the sixty’s and seventy’s decade, established with a minimum of six months before the noncardiac surgery. The recent advancements in the medical assessment of surgical risk based on the individual analysis of each case with availability of new therapeutic tools in reference to medical or dental treatment, allowing for new procedures that can be used in the execution of safer odontological surgery for each patients. This review of the literature shows the actual tendencies of the treatment of patients with Myocardial Infarction concerning specific care before, during and after surgery based on laboratory evaluation and drug therapy as well as the possibility of surgical treatment before six months post-infarction.
