Background: The purpose of this study was to determine the etiology and epidemiologic characteristics of sudden death at Ladoke Akintola University of Technology (LAUTECH) Teaching Hospital, South West Nigeria.
Methods: This was a retrospective descriptive study of all cases of natural unexpected death, either occurring out of hospital or less than 24 hours after admission to LAUTECH Teaching Hospital, over a nine-year period from January 2003 to December 2011. Data were generated from information in the case notes and autopsy reports for these cases.
Results: Sudden death accounted for 29 (4.0%) of 718 adult medical deaths and 1.0% of all adult medical admissions. Out-of-hospital deaths occurred in 72.4% of cases. The mean age of the patients was 46.8 ± 11.5 (range 25–74) years. The male to female ratio was 6.25:1. Cardiovascular disease were the most common cause of death (51.7%), followed by respiratory disease (20.7%), pulmonary thromboembolism (10.4%), central nervous system disease (13.8%), gastrointestinal disorders (13.8%), severe chemical/drug poisoning (13.8%), and combined cardiovascular and central nervous system disease (13.8%). Hypertension-related causes were responsible for 14/29 (48.3%) of the sudden deaths. Hypertensive heart disease accounted for 86.7% of the cardiovascular deaths, hypertensive heart failure accounted for 73.3%, whilst all heart failure cases accounted for 80.0%. Left ventricular hypertrophy was present in 69.2% of the patients with hypertensive heart disease. Moderate to severe atheromatous changes occurred in the aorta in 38.5% of patients aged ≥50 years. No case of myocardial infarction was found.
Conclusion: Hypertensive heart disease and hypertension-related disorders are the most common causes of sudden death in South West Nigeria, so effective public health strategies should be channeled towards prevention, detection, and treatment of hypertension.
