PHARMACOLOGICAL MODIFICATIONS TO BE TAKEN INTO ACCOUNT: In elderly patients, there is a modification in the distribution columns of drugs, an alteration in glomerular filtration (doses require adaptation) and tubular function (greater sensitivity to low salt diet and diuretics), and a reduction in the hepatic elimination capacity. FOR SYSTOLIC HEART FAILURE: The choice of drugs is in practice the same as that for younger patients: diuretics, antialdosterone agents, converting enzyme inhibitors, angiotensin II receptor antagonists, beta-blockers and digitalics. FOR DIASTOLIC HEART FAILURE: The therapeutic approach combines an etiologic treatment (blood pressure, myocardial ischaemia), prevention and the rapid treatment of the decompensation factors (atrial arrhythmia), a pharmacological treatment (converting enzyme inhibitors, angiotensin II receptor antagonists, and bradycardia lowering agents). Non-pharmacological measures include dietary restrictions, regular physical exercise, and education for the patient and the family.
