WHO adopted World Health Organization/International Society of Hypertension (WHO/ISH) risk charts to predict cardiovascular disease risk in low and middle income countries. The aim of this study was to estimate the cardiovascular risk in adults ≥40 years old by using the two versions of the WHO/ISH risk prediction charts “with and without cholesterol”, and to find out the risk by other parameters not found in the chart; also, to evaluate concordance between the two approaches. A cross-sectional study was conducted from August 2016 to February 2017 in two primary health care centers in Sulaimani City among 500 persons aged 40-82 years. The desired information was collected by using a pretested questionnaire; anthropometric measurements and laboratory investigations were also carried out for the participants. Cardiovascular risk was assessed by the WHO/ISH risk prediction charts for the Eastern Mediterranean region in category D. Mean age of the participants was 52.5(±9.55) years and 70.4% of the participants were females. Only 260 participants had the results of total cholesterol and triglycerides. The results revealed that, using the risk assessment charts with and without cholesterol, 22.3% and 19.2% respectively of the study population were in the ten-year cardiovascular risk category of ≥20%. Risk categories were concordant in 86.2% of the population; and when we applied single risk factor approach 51.5% would require drug treatment. The WHO/ISH risk chart is an affordable and simple tool to estimate cardiovascular disease risk. Nearly one fifth of adults aged ≥ 40 years in Sulaimani City are at high-very high risk of developing cardiovascular event in the next ten years as assessed by WHO/ISH risk prediction charts. The use of the without cholesterol version of the chart to estimate cardiovascular disease risk could be useful is settings where cholesterol cannot be measured.
