which is diastolic and systolic
Systolic dysfunction is a characteristic of dilated cardiomyopathy (DCM). It is also seen in some patients with hypertrophic cardiomyopathy (HCM) who develop progressive left ventricular dilatation and a decrease in LVEF. In general terms, systolic dysfunction is defined as an LVEF less than 40%. Diastolic dysfunction refers to cardiac dysfunction in which left ventricular filling is abnormal and is accompanied by elevated filling pressures. The diastolic phase of cardiac function includes two components.
Diastolic heart failure, a major cause of morbidity and mortality, is defined as symptoms of heart failure in a patient with preserved left ventricular function. It is characterized by a stiff left ventricle with decreased compliance and impaired relaxation, which leads to increased end diastolic pressure. Signs and symptoms are similar to those of heart failure with systolic dysfunction.
