Key result
QRISK3 identifies high 10-year cardiovascular risk in 29% of adults without prior CVD in Qatar.
Why the study?
Despite a high prevalence of metabolic and lifestyle-related risk factors in Qatar, no locally validated cardiovascular disease risk prediction tool exists.
Cross-Sectional (n=1,606)
Yes
A significant proportion of adults in Qatar's primary care settings are at high predicted 10-year cardiovascular risk, highlighting the utility of integrating the QRISK3 algorithm into routine assessment to guide targeted prevention.

Supports QRISK3 integration into routine primary care for targeted prevention; extends its utility to multi-ethnic Middle Eastern populations.
Cardiovascular diseases (CVDs) remain the leading cause of mortality worldwide, with a growing burden in the Eastern Mediterranean Region. Despite high prevalence of metabolic and lifestyle-related risk factors in Qatar, no locally validated risk prediction tool exists. This study aimed to explore the 10-year demographic patterns of CVD risk using the QRISK3 algorithm in Qatar’s primary care setting and identify key predictors of high risk. A cross-sectional study was conducted among adults (> 18 years) registered with the Primary Health Care Corporation (PHCC). QRISK3 scores were calculated for participants without established CVD using demographic, clinical, and laboratory data. High risk was defined as QRISK3 ≥ 10%. Multiple Logistic regression was used to identify independent predictors. Of 1,606 eligible participants, 15.6% had at least one CVD and another 24.5% were classified as high risk according to QRISK3, indicating that approximately 40% of adults assessed required some form of preventive or secondary care interventions. Age was the strongest predictor of high-risk group (OR = 612.6 for ≥ 60 years compared to < 40 years), followed by male sex (OR = 5.8), Southern Asian nationality (OR = 6.8), Class II obesity (OR = 6.4), and residence in Doha (OR = 2.3). The final model was 85.5% accurate in predicting the QRISK3 calculated group membership. Slightly less than one-third (29%) of adults without established CVD in Qatar’s primary care settings are at high predicted risk, highlighting the need for targeted prevention strategies. The study further advocates the significance and utility of QRISK3 as a risk-exploration tool for guiding prevention efforts. Its integration into routine primary care assessment may support early identification of individuals who would benefit from lifestyle counselling, risk factor modification, and targeted clinical & preventive interventions.

Syed et al. (2026) conducted a cross-sectional in Cardiovascular disease risk (n=1,606). QRISK3 algorithm was evaluated on High 10-year cardiovascular risk (QRISK3 ≥10%). Application of the QRISK3 algorithm in Qatar's primary care settings identified that 29% of adults without established cardiovascular disease have a high 10-year predicted risk (≥10%).
