Document Summary
Lab data ecg or ekg to determine location and size of infarct, and arrhythmias: process of healing can be followed by serial cardiograms. Complications: congestive heart failure due to badly damaged left ventricle which is unable to maintain normal cardiac function. Primary hypertension pressure >140/80: excessive vasoconstriction of small arterioles resulting in increased peripheral resistance, increased diastolic bp, increased force of ventricular contraction, compensatory increase in systolic pressure. Renal effects narrowed renal arterioles > decreased blood supply to kidneys > injury and degenerative changes in glomeruli and tubules > renal failure. 4: renal arteriole wall is greatly thickened and has concentric layers of smooth muscle cells and marked reduction in size of lumen. Types of heart failure - both failure associated with inadequate blood supply to the body"s needs: systolic heart failure inadequate ejection of blood from ventricles during systole; 20-60% less than normal.
