The reversal of the E/A ratio ('A' velocity becomes greater than 'E' velocity) is often accepted as a clinical marker of diastolic dysfunction, in which the left ventricular wall becomes so stiff as to impair proper filling, which can lead to diastolic heart failure. This can occur, for instance, with longstanding untreated hypertension.
Nearly half of American adults have high blood pressure, a condition that raises the risk of heart attack and stroke. Of those, only 25% have their high blood pressure under control. High blood ...
The first heart sound may be followed by a sharp ejection sound ("ejection click") best heard at the lower left sternal border and the apex, and, thus, appear to be "split". The ejection sound, caused by the impact of left ventricular outflow against the partially fused aortic valve leaflets, is more commonly associated with a mobile bicuspid ...

Defects in cellular processes such as autophagy and mitophagy are thought to contribute to the development of diabetic cardiomyopathy. [2] Diabetic cardiomyopathy is characterized functionally by ventricular dilation, enlargement of heart cells, prominent interstitial fibrosis and decreased or preserved systolic function [5] in the presence of a diastolic dysfunction.
According to Laffin, any activity that raises the heart rate and puts a healthy bit of aerobic stress on the body also benefits heart health by relieving stress, widening the blood vessels and ...
Pulse pressure is calculated as the difference between the systolic blood pressure and the diastolic blood pressure. [3] [4]The systemic pulse pressure is approximately proportional to stroke volume, or the amount of blood ejected from the left ventricle during systole (pump action) and inversely proportional to the compliance (similar to elasticity) of the aorta.
How the heart works during its filling period still has many misconceptions remaining. To better understand diastolic function, it is crucial to realize that the left ventricle is a mechanical suction pump at, and for a little while after, the mitral valve opening. [5] In other words, when mitral valve opens, the atrium does not push blood into ...
