Treatment of congestive heart failure
Congestive heart failure (CHF) occurs whenthe cardiac output is inadequate to provide theneeds of the body. Patients with CHF developprogressively severe symptom of fatigue, dyspnea,chest pain, syncope, and death. Myocardialinfarction, viral infection, valvular disease, alcoholand so on
Congestive heart failure (CHF) occurs when the cardiac output is inadequate to provide the needs of the body. Patients with CHF develop progressively severe symptom of fatigue, dyspnea, chest pain, syncope, and death. Myocardial infarction, viral infection, valvular disease, alcohol and so on

direct cause of CHF isthought to be due towithdefectiveexcitation-contractioncoupling,andsystolicdiastolicventricularprogressivedysfunction or by an increased workload imposedon the heart.CHF is accompanied by abnormal increases inblood volume and interstitial fluid. The heart, veinsand capillaries are therefore generally dilated withblood. hence the term “congestive " heart failure
