Purpose: Type 2 diabetes (T2D) and asthma are independent risk factors for cardiovascular disease (CVD), but CVD risk is reduced in individuals with T2D + Asthma compared to those with T2D alone when using the 2013 ACC/AHA CVD Risk Score. Because these guidelines may overestimate CVD risk by up to 20%, revised risk equations have recently been proposed. We hypothesize that using these revised risk score equations will not alter the relationship between asthma, T2D, and CVD Risk Score.

Methods: Data were extracted from Electronic Health Record using ICD-9/10 codes. Patients with both T2D and Asthma (n=603) were identified and compared to a group of matched patients with T2D Alone (n=603). Estimates of the 10-year risk of a major CVD event were derived using generalized linear models.

Results: As shown in the Table, 10 year CVD risk was significantly increased in the T2D Alone group compared to the T2D + Asthma group using both the 2013 ACC/AHA CVD Risk Score estimates and the revised 2018 CVD Risk Score estimates. CVD risk is approximately 2% higher in both groups using the newer estimates.

Conclusions: In this matched, case controlled retrospective study, Asthma conferred a protective effect against CVD risk over the next 10 years for patients with co-morbid T2D. This result was initially demonstrated with the 2013 ACC/AHA Risk Score estimates and confirmed with the 2018 revised Risk Score estimates.
