Abstract

Abstract: This study investigated the effect of essential hypertension on left ventricular remodeling and left heart failure in patients with hypertrophic obstructive cardiomyopathy. 140 patients with hypertrophic obstructive cardiomyopathy were selected, among them 54 patients were complicated with essential hypertension, and all patients were examined by echocardiography. The left ventricular end diastolic diameter and end systolic diameter in patients with hypertension were significantly higher than those in patients without hypertension (P<0.05), while the ventricular septal thickness and left ventricular ejection fraction were significantly lower than those in patients without hypertension (P<0.05). The incidence rate of left heart failure in patients with hypertension was significantly higher than that in patients without hypertension (P<0.05). Logistic regression analysis showed that the age, systolic blood pressure and left ventricular ejection fraction were the influencing factors of left heart failure in patients with hypertrophic obstructive cardiomyopathy with hypertension (OR=1.759, 2.273 and 0.576, P<0.05). Essential hypertension can aggravate left ventricular remodeling in patients with hypertrophic obstructive cardiomyopathy, and have an increased risk of left heart failure.

Key words: essential hypertension, hypertrophic obstructive cardiomyopathy, left ventricular remodeling, left heart failure, color doppler ultrasound
