Cardiovascular risk assessment tools in Asia

Area of Science:

• Public Health
• Epidemiology
• Cardiology

Background:

• Cardiovascular disease (CVD) poses a significant global health burden, particularly in Asia.
• Existing CVD risk assessment tools are predominantly Western-based.
• Asian populations exhibit distinct risk factor profiles and CVD patterns compared to Western populations.

Purpose of the Study:

• To highlight the limitations of Western CVD risk assessment tools in Asian populations.
• To emphasize the need for culturally specific or adapted risk models.
• To guide the development and application of appropriate CVD risk assessment strategies in Asia.

Main Methods:

• Review of existing literature on CVD risk assessment tools.
• Analysis of epidemiological data comparing Western and Asian populations.
• Discussion of the implications of differing risk factor prevalence and CVD profiles.

Main Results:

• Western CVD risk assessment tools show limitations when applied to Asian populations due to differences in hypertension, cholesterol levels, metabolic disorders, and stroke-to-coronary heart disease ratios.
• Existing Asian-specific models like China-PAR and JALS score are validated for national use.
• Many Asian regions currently utilize non-recalibrated established models.

Conclusions:

• Recalibration or development of new CVD risk assessment tools is essential for Asian populations.
• Hypertension requires greater emphasis in Asian CVD risk assessment due to higher stroke incidence.
• Adapting existing models with local epidemiological data is a viable alternative where resources are limited.
