Infarto agudo al miocardio en octogenarios, caracterización y comparación con pacientes menores en 20 años de registro / Acute myocardial infarction in octogenarians, characterization and comparison with younger patients in 20 years of registry

ABSTRACT

Cardiovascular diseases are the main cause of death in Chile, being acute myocardial infarction (AMI) the most frequent. Its incidence increases with age, so, as the population gets older; a higher number of cases is expected. Despite this, AMI within octogenarian patients (OP) has been understudied in our country and worldwide; there are no specific guidelines for their management, only a few isolated studies that reveal the poor applicability of the standard treatments indicated in AMI clinical guidelines. Objective: To describe the clinical features, initial treatment, in-hospital evolution and five-year outcome of OP with AMI, and compare them to patients under 80 years of age. Method: Consecutive registration of all patients diagnosed with AMI that were hospitalized in our coronary unit between 1988 and 2007. Description of clinical features, in-hospital and 5-year evolution of all OP cases. Comparison to the younger group of patients through chi-square or t-student tests, considering p-value...
