Echocardiographic analysis of ventricular septal dynamics in hypertrophic cardiomyopathy and other diseases

Abstract

It has been suggested that the adynamic or hypokinetic appearance of the ventricular septum is a unique echocardiographic feature of hypertrophic cardiomyopathy (HC). To determine how characteristic of HC the adynamic septum is, 70 patients with this disease, and 31 with other cardiac diseases that produce left ventricular (LV) hypertrophy and pressure overload (aortic valvular stenosis or systemic hypertension), and 25 subjects with normal hearts were studied by echocardiography. On M-mode echocardiography, 53 of 70 patients (75%) with HC had an abnormally low value for percent systolic thickening of the septum associated with either reduced or normal septal excursion; however, 17 patients (25%) showed normal septal dynamics. Twenty of 31 patients (64%) with other cardiac diseases that produce pressure overload showed normal septal thickening and excursion, while 11 (36%) had reduced systolic thickening associated with either diminished or normal excursion. Greatly reduced values for percent systolic thickening of the septum were present both in patients with HC (13 +/- 1%) and in patients with other cardiac diseases (21 +/- 2%). However, differences in systolic septal thickening between the 2 groups were largely a manifestati...Continue Reading

Cardiovascular Diseases: Risk Factors

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
