The clinical and echocardiography features of basal septal hypertrophy / 中华超声影像学杂志

ABSTRACT

Objective To explore the prevalence and clinical and echocardiography features of the basal septal hypertrophy(BSH).Methods Clinical and echocardiography data of 1 056 elderly population in an urban community of Beijing were analyzed.BSH was defined as the thickness of basal interventricular septum ≥1.4 cm and basal septal/mid septal ≥1.3.Data were compared between BSH and non-BSH,and the risk factors of BSH were evaluated.Results The prevalence of BSH in this population was 7.39%(95%CI:5.8%-9.0%).BSH was not associated with current cardiovascular diseases (P >0.05).Its correlates in logistic analysis included male,diabetes mellitus,small end diastolic left ventricular dimension and abnormal left ventricular diastolic function (P <0.05),with OR 0.49(0.29,0.83),1.99(1.18,3.37),2.24 (1.35,3.72),0.39(0.26,0.59),and 1.96(1.01,3.81),respectively.Conclusions BSH is common in elderly community population and not associated with cardiovascular diseases.Its risk factors included male, obesity,diabetes mellitus,small end diastolic left ventricular dimension and abnormal left ventricular diastolic function.
