Abstract

BACKGROUND: Left ventricular hypertrophy is a forerunner of coronary heart disease, congestive cardiac failure, stroke and may also lead to sudden death. Estimation of left ventricular mass by echocardiography offers prognostic information better than the evaluation of traditional cardiovascular risk factors.

OBJECTIVE: The aim of this study was to determine the relative contributions of haemodynamic and metabolic factors affecting left ventricular mass in non-diabetic patients with essential hypertension.

MATERIAL AND METHODS: 100 non-diabetic hypertensive patients were taken. The association between age, gender, smoking, alcohol, height, weight, heart rate, clinic blood pressure, fasting blood glucose, lipid profile, haemoglobin, body mass index and stroke volume with LV mass was studied. Left ventricular mass was measured by using standard M-mode echocardiography measurement obtained by way of standard recommended by the American Society of Echocardiography.

RESULTS: Left ventricular mass was analyzed as a continuous variable. In males body mass index (r = .35, p < .004) and stroke volume(r = -.26, p<.039) were significantly correlated with LV mass. In females body weight was significantly related to left ventricular mass(r = .36, p < .02). The independent association between significant factors and left ventricular mass was assessed by stepwise multivariate logistic regression. Body mass index and systolic blood pressure came as independent determinants of left ventricular mass in all patients. A maximum of 13% of left ventricular mass variability could be explained by these two factors.

CONCLUSION: In untreated patients with hypertension patient's body mass index and systolic blood pressure are independent predictors of left ventricular mass after adjustment for other haemodynamic and metabolic factors. They explain a maximum of 13% of left ventricular mass variability. More knowledge is needed about factors that may alter cardiac morphology in the evolution of hypertensive patients.
