Epidemiology of CVD in Bangladesh
CVD Burden in Bangladesh
Overview
Cardiovascular disease (CVD) is the leading cause of death in Bangladesh, accounting for approximately 17% of all deaths. The country is experiencing a rapid epidemiological transition driven by urbanisation, dietary shifts, physical inactivity, and an ageing population.
Key Statistics
- Hypertension prevalence: 20–34% urban; 11–13% rural
- Diabetes mellitus: estimated 8.4 million adults
- Coronary heart disease: 12% of national mortality
- Mean age at first acute MI in Bangladesh: 52 years — a decade younger than high-income countries
- Stroke 30-day case fatality: 24.6%
Risk Factor Profile
The INTERHEART sub-study found that 9 modifiable risk factors account for nearly 90% of AMI population attributable risk in Bangladesh — tobacco, dyslipidaemia, abdominal obesity, hypertension, diabetes, psychosocial stress, poor diet, alcohol, and physical inactivity.
Global Context — Where Bangladesh Stands
Global Burden of Disease
According to the GBD Study, Bangladesh ranks among the top 30 countries for age-standardised CVD mortality per 100,000 population — significantly above the global average.
WHO STEPS Data Comparison
- Hypertension prevalence: Bangladesh 34% vs South Asia avg 28%
- Physical inactivity: Bangladesh 63% vs South Asia avg 54%
- Tobacco use (adults): Bangladesh 39% vs South Asia avg 30%
- Daily salt intake: Bangladesh 10.2g vs WHO target <5g
Epidemiological Transition
Bangladesh is in Stage 3 of Omran's epidemiological transition. Without urgent action on primary prevention and health system strengthening, CVD deaths are projected to increase by 40% by 2035.
