Abstract

Introduction

Cardiovascular disease (CVD) risk prediction plays a vital role in early detection of high-risk individuals. This study aimed to compare the risk of a cardiovascular event using the World Health Organization (WHO)/International Society of Hypertension (ISH) risk prediction charts and Framingham risk score (FRS).

Methods

A descriptive cross-sectional study was conducted among three hundred sixty six, 30 to 60 year old adults from Sabaragamuwa province, Sri Lanka. Participants were selected using a three-stage random sampling method, and the WHO STEPS wise approach was used to collect data. The ten-year risk was calculated using both methods and a risk ≥20 % was considered a high risk. Chi-square test was used to compare the calculated risk at a p-value of 0.05.

Results

Framingham risk score categorized 25.1% of the participants into the high-risk category, whereas it was 2% with the WHO risk prediction charts (p<0.001). Nearly 25% of the participants who were classified into the <10% risk category in WHO risk prediction charts were recognized as having high risk by the FRS. Moreover, 30.3% of the participants were classified as having 10-20% CVD risk by FRS, while WHO/ISH charts categorized them as <0% of CVD risk. The agreement between these two methods was very poor (k value= -0.002, p=0.950).

Conclusion

FRS identified a higher proportion of participants as having high risk compared to the WHO risk prediction charts. The discrepancy between these two methods is disturbing since none of these methods has been recalibrated for Sri Lanka.
