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 diastolic pressure is the pressure of the blood between heartbeats. The numbers are usually written as a fraction with the systolic above or to the left. An example is 120/80 mm Hg (millimeters of mercury), a normal adult blood pressure. Both numbers count. Your blood pressure is high if the systolic pressure is 140 or above, or the diastolic pressure is 90 or above, or both are high.
