Características clínicas, angiográficas, estrategias terapéuticas y pronóstico de pacientes jóvenes con síndrome coronario agudo

摘要

Background Patients with acute coronary syndrome have clinical differences which are determined by the age-group to which they belong. Yet, few studies have compared young patients versus elder patients presenting with this syndrome. Objectives To describe the clinical and angiographic characteristics, the therapeutic uses and the outcome of young patients with acute coronary syndrome, and to compare them with those of elder patients. Methods A total of 5,055 patients with diagnosis of acute coronary syn-drome, included in the Epi-Cardio registry, were analyzed. Men ≤ 45 years and women ≤ 50 years were considered young. Results Young patients represented 10.3% of the population (519) and 89.7% (4,536) were elder patients. Among young pa-tients, 49.9% presented ST-segment elevation acute coronary syndrome and 50.1% had non ST-segment elevation. In elder patients, ST-segment elevation acute coronary syndrome occurred in 38.4% and 61.6% had non ST-segment eleva-tion (p Conclusions ST-segment elevation acute coronary syndrome was more frequent among young patients compared to elder patients. Mortality was three to four times greater in elder patients. The difference in the clinical presentation is justified by the profile of cardiovascular risk and extension of coronary artery disease of both groups.
