02.10.2017: The symptoms of heart failure are reduced exercise tolerance, breathlessness and dependent oedema, due to reduced cardiac output or elevated filling pressures (1). Cardiac output depends on both adequate contractility (systolic function) and effective filling between contractions (diastolic function...
