10-Year Cardiovascular Risk in Hypertensive Patients: Insights from Central Vietnam Using WHO 2019 Chart

Background: Assessing the 10 -year cardiovascular disease (CVD) risk is crucial for effective prevention and management. Despite its significance, information is limited on CVD risk among hypertensive patients in primary care in Central Vietnam. We conducted this study to estimate 10-year CVD risk in primary care settings and explore its associated risk factors, using the 2019 WHO CVD risk chart. Methods and Results: This cross-sectional study collected socio-demographic and clinical data through a standardized questionnaire. Cardiovascular risk was estimated using the WHO CVD risk charts for Southeast Asia. The prevalence of low, moderate, and high CVD risk was 52.1%, 38.9%, and 9.0%, respectively. Notably, men had significantly higher rates of moderate (48.6%) and high (17.6%) CVD risk than women (31.4 and 2.4%, respectively) ( P <0.001). Age was a significant factor, with an increasing prevalence of moderate and high CVD risk as age advanced. Specifically, the 50-59 age group had a moderate risk of 18.6%, rising to 69.9% in the 70-74 age group. High CVD risk increased from 0.6% to 27.6% in the same age groups. Lower educational levels were associated with a higher proportion of moderate CVD risk. Smoking and excessive alcohol consumption were linked to elevated CVD risks (25.0% and 30.0%, respectively), surpassing those without these behaviors. Similar trends were observed for individuals with diabetes, high total cholesterol, and high blood pressure. Conclusion: Approximately one-tenth of hypertensive patients face a high risk of developing CVDs within the next 10 years. A comprehensive approach, encompassing behavioral changes and the management of metabolic risk factors, is essential to reduce CVD risk effectively.
