The significance of the WHO/ISH absolute cardiovascular risk prediction scores among recent stroke survivors in Ghana-Insights from the PINGS2 multicenter study.

Background: The leading cause of stroke remains atherosclerotic cardiovascular disease. The World Health Organization/International Society of Hypertension risk score represents an effort to produce a risk assessment tool for atherosclerotic cardiovascular disease that is regionally specific. No previous work has described absolute cardiovascular risk scores among recent stroke survivors in West Africa via this tool. Methods: A cross-sectional analysis of baseline data from the multicenter, phase III randomized, open-label, clinical trial, Phone-based Intervention under Nurse Guidance II (PINGS-2), was performed. Data from 414 participants who had recently survived a stroke and met the age range compatible with the risk estimation tool were analyzed. The WHO/ISH score was calculated for each participant and categorized into low, moderate, and high/very high CVD risk scores. Demographic data, medical histories, anthropometry, vascular risk profiles, stroke types and severity indices were compared across CVD risk categories. Multivariate logistic regression was performed to further examine variables significantly associated with WHO/ISH CVD risk via univariate analysis. Results: The mean age of the study population was 58 years (SD = 12), with the majority being male (56.5%). Ischemic strokes ( Conclusion: The majority of recent stroke survivors in this multicenter Ghanaian cohort were classified as having low absolute CVD risk. This raises questions about the performance of the WHO/ISH risk assessment tool in this population.
