ABSTRACT

Cardiovascular diseases are the first cause of death in elderly patients. So it seems important to estimate the adequacy of the medical prescriptions to the guidelines in this population and for these diseases. A retrospective analysis was performed in nine hospitals on 736 patients aged 65 years old and over hospitalized in the acute care geriatric unit. Cardiovascular prescribing were analyzed for each patient according to STOPP and START. The population (n=736) has a mean age of 86.7 years and belongs in 45.0% of the cases to the group of dependence GIR3-4. According to STOPP, two inappropriate prescriptions are noticed calcium channel blockers with chronic constipation concerning 9% of the included population and aspirin at dose > 150 mg/day representing 8.4% of this population. According to START, angiotensin converting enzyme inhibitor are under-prescribed in elderly patients with heart failure (140 patients = 19.0% of the population) and following acute myocardial infarction (116 patients = 15.8%). Anticoagulation in patients with atrial fibrillation is also under-prescribed 82 patients are concerned (11.0% of the population). The prescription of ACE inhibitor is influenced by renal insufficency in patients with heart failure. The anticoagulation in atrial fibrillation is age and dependence-related. This analysis demonstrates an inadequacy between the clinical practice and guidelines for two major cardiovascular diseases the heart failure and the atrial fibrillation. The importance of the inadequacy was suspected of opportunities for improvement, in particular in the presence of their risk factors very elderly patients, loss of autonomy and renal insufficiency.
