Key result
Cardiac causes account for ~65% of sudden unexpected deaths, linked primarily to standard vascular risk factors.
Why the study?
The incidence and causes of sudden death vary across societies and are influenced by demographic and clinical factors, which require characterization in the Bangladeshi population.
Population
414 sudden death cases of all ages at Emergency Room of Ibrahim Cardiac Hospital, Dhaka, Bangladesh

Traditional CV risks predominate in cardiac sudden deaths; extends observational data to South Asian cohorts but leaves causal inference and practice change open.

In a Bangladeshi tertiary cardiac hospital emergency department, sudden death was predominantly attributed to cardiac causes and strongly associated with traditional cardiovascular risk factors, particularly in middle-aged men.
Taimur et al. (2015) conducted an observational in Sudden unexpected death (n=414). Cardiovascular risk factors (hypertension, dyslipidaemia, smoking, CKD) vs. Absence of risk factors was evaluated on Presumed cardiac cause of death (p=<0.001). Among 414 cases of sudden unexpected death, 65% were presumed to be of cardiac origin, which was significantly associated with a history of hypertension, dyslipidaemia, smoking, and chronic kidney disease.
