MANZUR, Fernando; ESPANA, Harold  and  DUENAS, Carmelo. Variables associated to mortality for myocardial infarction in adults over 75 years in Cartagena de Indias , Colombia: a pilot study. Rev. Colomb. Cardiol. [online]. 2011, vol.18, n.4, pp.192-198. ISSN 0120-5633.

Introduction: the increment of elderly population enables the observation of myocardial infarction in people aged 75 years or more. Approximately 30% of the cases of acute myocardial infarction are present at these ages. However, the variables related to hospital mortality in Cartagena de Indias, Colombia, have not been explored. Objective: explore some variables associated to mortality for myocardial infarction in hospitalized adults over 75 in Cartagena de Indias, Colombia. Method: we performed an analytical cross-sectional observational study. The clinical records of patients hospitalized for acute myocardial infarction during 2008 and 2009 were reviewed. We made a logistic regression in order to adjust the associations. Results: eighty adults with ages between 75 and 94 years participated in the study. Mean age was 80,7 ears; 50% were women. During the hospitalization, twenty patients (25,0%) died. Mortality was significantly associated to Killip III-IV (OR=5,93; IC 95% 1,80-19,53). Conclusions: the presence of Killip III-IV on admission due to acute myocardial infarction is associated to higher mortality in adults over 75 years. Studies with a higher number of participants are required to corroborate these findings.
