Heart failure is not a single pathological diagnosis, but a clinical syndrome consisting of cardinal symptoms (e.g. breathlessness, ankle swelling, and fatigue) that may be accompanied by signs (e.g. elevated jugular venous pressure, pulmonary crackles, and peripheral oedema). It is due to a structural and/or functional abnormality of the heart that results in elevated intracardiac pressures and/or inadequate cardiac output at rest and/or during exercise. Identification of the aetiology of the underlying cardiac dysfunction is mandatory in the diagnosis of HF as the specific pathology can determine subsequent treatment. Most commonly, HF is due to myocardial dysfunction: either systolic, diastolic, or both. However, pathology of the valves, pericardium, and endocardium, and abnormalities of heart rhythm and conduction can also cause or contribute to HF.~Cardiomyopathies are defined by the WHO as diseases of the myocardium associated with cardiac dysfunction, Cardiomyopathies are categorized into dilated, restrictive, hypertrophic, and unclassified based on the predominant pathophysiologic characteristics. A new category has been added to include right ventricular abnormalities. The disorders that are associated with systemic or certain cardiac diseases are called specific heart muscle diseases and include ischemic cardiomyopathy, valvular, hypertensive, inflammatory, metabolic, peripartal, general systemic disease, muscular dystrophies, neuromuscular disorders, and toxic and hypersensitivity reactions. The unclassified cardiomyopathy category includes disorders such as fibroelastosis, noncompacted myocardium, and systolic dysfunction with minimal dilation.~Patiant admitted in I.C.U. with heart failure who already have cardiomyopathy Some patiants discharge without any comorbidies and some acquire renal failure, respiratory failure,MCS, sepsis, and some were associated with mortality . Significant comorbidities associated with these hospitalizations included arrhythmias, renal failure , cerebrovascular disease, and hepatic impairment.
