Smoking, obesity, sedentary lifestyle, smoking: hf is most common reason for hospitalization of pts > 65 yrs, hypertension. Years of use: nsaids over a long period of time - vasoconstriction can damage kidneys. Leads to na & h2o retention: all add to perfusion problems. Hf: etiology & pathophysiology: may be caused by an interference with normal mechanisms regulating cardiac output (co) Co = hr x sv (amount of blood pumped from lv with each contraction) Preload: volume of blood in ventricle at end of diastole, afterload. Force ventricle must develop to eject blood into circulatory system: myocardial contractility, heart rate, metabolic state of individual. Systolic failure contraction problem: most common cause of chf, mi - heart wall weakens from extra workload (cid:862) (cid:395)ueeze(cid:863) of (cid:448)e(cid:374)t(cid:396)i(cid:272)les is issue.
