Objective: To determine the proportion of deaths due to confirmed myocardial infarction (CMI) and the aetiology of sudden death at the Port-of-Spain General Hospital (A&E) department for January to June 2008.
Methods: This retrospective study utilized the death register to determine the number of A&E deaths for the study period. Patients dying from MI were investigated using records to obtain ECG and postmortem reports.
Results: During the study period, 150 patients were certified dead in the A&E department. Cardiovascular causes accounted for 42.7% (n = 64) of deaths. Confirmed MI accounted for 27.3% (n = 41) of deaths and 3.3% (n = 5) were certified by a private practitioner without post-mortem examination and were classed as unconfirmed MI. Trauma related deaths followed with 27.3% (n = 41). Deaths from firearm injury were the next most common, 19.3% (n = 29).
The mean age of patients dying from CMI was 64.1 years with a male to female ratio of 2:1. Males died from CMI on average 6.3 years before females. Mortality peaked for females in the 80 – 89-year age group while for males it was the 60 – 69-year age group. Afro-Trinidadians accounted for 58.5% (n = 24) deaths due to CMI. More CMI patients had combined DM and HTN 36.6% (n = 15) than either condition alone. Afro-Trinidadians were more likely to be hypertensive and Indo-Trinidadians, diabetic. Death on arrival was the most common presentation for MI patients, 65.9% (n = 27).
Conclusions: This study shows that the main cause of death in the A&E Department at the Port-of- Spain General Hospital was MI. Trauma related deaths followed. Men died from MI at an earlier age than women. Most MI patients were dead on arrival.
