Diastolic heart failure is defined clinically when signs and symptoms of heart failure are present in the presence of preserved left ventricular systolic function (ejection fraction >45%). The ...

Roughly half of adolescents and young adults with either type 1 or type 2 diabetes for about a decade had diastolic dysfunction, a direct precursor to heart failure, in a multicenter echocardiography ...

The septum of the heart is a wall of tissue that separates the left and right sides of the heart and enables blood to flow as it should. It consists of the atrial septum and the ventricular septum.

With numerical simulations, researchers have demonstrated a new way to time weak electrical pulses that can stop certain life-threatening arrhythmias. The group shows that timed pulses are successful ...

When your electrical system is working normally, the two upper chambers of the heart (atria) contract and pump blood into the two lower chambers (ventricles) in a well-coordinated way. This results in ...

What are the grades of diastolic dysfunction measured by echocardiography, and what are the clinical ramifications of each? Diastolic dysfunction occurs when the left ventricular myocardium is ...

Atrial fibrillation and ventricular fibrillation are both types of irregular heartbeats (arrhythmias). Atrial fibrillation (AFib) affects the two upper chambers of your heart. Ventricular fibrillation ...

The selective cardiac myosin activator omecamtiv mecarbil has been shown to improve cardiac function in patients with heart failure with a reduced ejection fraction. Its effect on cardiovascular ...
