Document Summary
Systolic hf: can"t pump blood w enough force bc heart muscle weaker/smaller = Diastolic hf: not enough ventricular lling bc larger heart muscle = less blood pumped out. = sv = co (less blood pumped from lv/beat) Lek side heart failure uid buildup/ conges:on in lungs. Right side hf conges:on in lower extremi:es. Cause of ex capacity is mul:factorial. Lv failure cardiac disease. Respiratory sys pulmonary disease. Peripheral vasculature vascular disease (disease of blood vessels of circulatory sys) Limited func:onal capacity in: cv sys, respiratory sys, peripheral :ssue (skeletal m) Hallmark symptom of heart failure: exercise intolerance. 3 main features of heart failure = exercise intolerance: Heart failure is a cardiovascular respiratory disease. Peripheral arterial disease: obstructed (narrowing/ blocked) arteries (other than those that supply the heart and brain) due to atherosclerosis. Pad aka arterial disease of infra- renal aorta and arteries of lower extremi:es. Blood perfusion in peripheral *ssue & skeletal muscle func*on.
