Everyone is familiar with white adipose or fat tissue, which provides insulation and, by storing triglyceride, serves as an energy depot. Many mammals also have brown adipose tissue, which also stores triglyceride, but has the unique ability to generate heat.
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.
The systolic pressure (first or top number) measures the force when your hearts beats; the diastolic pressure (second or bottom number) is a measurement of the heart at rest. For example, someone with a systolic reading of 120 mm Hg and a diastolic reading of 80 mm Hg would have a blood pressure of 120 over 80.
