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 their 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 (no...

Background There is evidence that statins induce the regression of cardiac hypertrophy in a transgenic rabbit model of hypertrophic cardiomyopathy. Methods and Results The association between treatment with statins and the regression of cardiac mass (left ventricular mass index, LVMI) was investigated in a case - control study using transthoracic echocardiography in 304 patients with angina who...

The objective of this study was to clarify the relationship between afterload, which consists mainly of the vascular reflection wave, and left ventricular hypertrophy in patients with untreated essential hypertension using the fingertip photoplethysmogram (PTG) and second derivative wave (SDPTG) methods, the simplest and most convenient tools for pulse wave analysis. The augmentation index (AI)...

AIM It was the aim of our study to determine whether myocardial fibrosis influences physiologic or non-physiologic left ventricular (LV) hypertrophy in severe aortic stenosis. METHODS Myocardial fibrosis was evaluated using specimens taken from the ventricular septum in 79 patients submitted to aortic valve replacement because of symptomatic aortic stenosis. Patients were considered to have p...

OBJECTIVE The present study aimed to evaluate left ventricular (LV) systolic function in patients with iron deficiency anemia (IDA) by 3 dimensional speckle-tracking echocardiography (3DSTE). METHODS Participants were grouped by hemoglobin (Hb) levels in order to study the effect of anemia on cardiac function. Group A included 40 healthy volunteers. Eighty-three patients who were diagnosed wi...

BACKGROUND The left ventricular hypertrophy (LVH) is an important and independent cardiovascular risk factor. There is a scarcity of studies in Brazil designed to test the efficacy of the electrocardiogram (ECG) in the diagnosis of this important pathological process. OBJECTIVE To evaluate a new electrocardiographic score for the diagnosis of LVH by ECG: the sum of the highest amplitude of th...

The results of anemia correction by recombinant human erythropoietin (rHuEPO) therapy with regard to cardiac function and left ventricular hypertrophy in dialysis patients are controversially discussed. The aim of the study was to assess the effects of therapy rHuEPO on cardiac morphology and function in dialysis patients. We studied 11 clinically stable hemodialysis patients with severe renal ...

Previous Background: Hemodynamic factors, like blood pressure, have been established to be major determinants of cardiac left ventricular structure. However, several factors other than blood pressure to influence cardiac mass have been implicated. When we did medical survey, cardiac left ventricular mass index (LVMI) of one ethnic group that had higher blood pressure was found to be smaller tha...

OBJECTIVE Left ventricular mass is an important determinant of diagnosis and prognosis in patients with heart disease. The aim of the present study was to validate measurement of the left ventricular mass index (LVMI) by quantitative gated myocardial SPECT (QGS) with 99mTc-tetrofosmin by comparing it with echocardiography. METHODS QGS and M-mode echocardiography (Echo) were performed within o...
