Asociación de la concentración de material particulado en Bogotá con infarto agudo de miocardio

Abstract

Background: Air pollution has important effects on the respiratory and cardiovascular systems. The aim of this research is generate evidence that allow us to establish an association between the myocardial infarction and the environmental PM10 concentration, as a preliminary research for a set of patients in Bogotá. Methods: The association between the particulate matter concentration (PM10 concentration registered on the closest monitor located from the place reported by patient as the place where the symptoms began) and the myocardial infarction was established using a case crossover design. Information from the medical record of patients with myocardial infarction diagnosis in the FSFB’s Emergency Room and the PM10 concentration registered on air quality monitor, was used. Results: The association between PM10 concentration and the myocardial infarction diagnosis is statistically significant for three control moments: 2 hours before the event, 24 hours before the event and 48 hours before the event. Discussion: This research suggests that high PM10 environmental concentrations increase the risk of developing myocardial infarction, especially on patients with previous coronary disease. Moreover, it brings attention on the importance of generate policy actions that decrease air pollution in order to protect population health.
