Cardiac failure in ischemic cardiopathy

: Heart failure is a major cause of morbidity and mortality and represents an important recognized health problem. Heart (or cardiac) failure is the pathophysiological state in which a myocardial dysfunction is frequently but non always responsible for the inability of the heart to pump blood at a rate commensurate with tissues metabolic requirements. Ischemic heart disease is the commonest cause of heart failure frequently associated with left ventricular systolic dysfunction, although some patients, particularly the elderly, have diastolic dysfunction. Coronary heart disease is responsible for left ventricular systolic dysfunction (and cardiac failure) in the acute and chronic stage. Myocardial dysfunction is usually a consequence of myocardial infarction that may lead to ventricular remodeling with compensatory dilation and hypertrophy and subsequent systolic and diastolic dysfunction resulting in heart failure. Many patients with heart failure and/or left ventricular dysfunction are unknown. The echocardiographic screening of patients with known or suspected left ventricular dysfunction remains an important topic for future clinical epidemiological research and allows for improvement of therapeutic management of patients with cardiac dysfunction.
