Abstract
Objectives: To investigate cardiovascular disease (CVD) prevalence in adult patients with type 2 diabetes mellitus (T2DM) in Saudi Arabia using data from the CAPTURE cross-sectional study. Methods: CAPTURE was a non-interventional, multinational study carried out between December 2018 and September 2019. In Saudi Arabia, clinical (including medication) and demographic data were collected across 7 sites (Alhada Armed Forces Hospital, Taif; King Saud University Medical City, King Saud University, Riyadh; Specialized Medical Centre Hospital, Riyadh; King Abdulaziz University Hospital, Jeddah; King Abdulaziz Hospital for National Guard, Al Ahsa; Diabetes and Endocrinology Center, Buraidah; and Dallah Hospital, Riyadh, Saudi Arabia) from adults aged >= 18 years. The prevalence of CVD was estimated and weighted according to care setting, with data between groups not statistically compared. Results: Among the 883 adults enrolled in this study (566 from primary care, 317 from secondary care), 158 had established CVD, making the weighted prevalence of 18% (95% CI: [15.5-20.5]). The weighted prevalence of atherosclerotic CVD was 15.1% (95% CI: [12.8-17.5]), accounting for 82.4% of the CVD cases. Coronary heart disease was the most common subtype of CVD (13.4%), followed by cerebrovascular disease (1.7%). A total of 23.6% of patients were treated with glucose-lowering agents with proven cardiovascular benefit. Conclusion: In Saudi Arabia, approximately one in 5 adults with T2DM had established CVD, lower than the global prevalence, possibly because of disparities in patient characteristics, potential genetic predispositions, or a lack of accurate documentation due to poor coordination between care settings.
