Mortalidad en infarto agudo de miocardio con elevación del segmento ST de acuerdo al Killip Kimball, en la fundación Santa Fe de Bogotá de 2011-2020

Abstract

Introduction ST elevation acute myocardial infarction is one of the leading causes of global morbidity and mortality. The Killip-Kimball scale described in 1967 allows rapid clinical stratification of the severity of the infarction. However, the frequency of mortality in the Colombian population is unknown. This work seeks to describe the mortality at 28 days for the different levels of the Killip-Kimball scale. Materials and methods A retrospective cohort study with clinical follow-up at 28 days where the Killip-Kimball scale was evaluated at admission in patients admitted with acute myocardial infarction with ST elevation at the Fundación Santa Fe de Bogotá from January 2010 to December 2020. Results 413 patients with 28 (6.8%) deaths were collected; of these 327 (79.2%) were Killip I with 9 deaths, 33 (7.9%) Killip II with 4 deaths, 22 (5.4%) Killip III with 4 deaths, and 31 (7.7%) Killip IV with 12 deaths; with mortalities of 2.8%, 12.2%, 18.2% and 38.8% respectively. Conclusions The probability of death at 28 days increases with a higher score on the Killip-Kimball scale at admission. Our results are comparable to the mortality found in high-income countries.
