Introduction: The leading non-neoplastic cause of morbidity and mortality in cancer survivors is cardiovascular disease, of which coronary artery disease (CAD) is emerging as a significant burden. Inherent in screening is an understanding of pre-test risk, and the association of CAD with particular cancers is not well-defined.

Hypothesis: To develop a systematic review to explore differential frequencies of CAD in survivors of different cancers.

Methods: We searched MEDLINE and EMBASE (2006-2021) for studies of CAD in survivors. For studies without a control population, we utilized a community prevalence for CAD from the 2021 US. National Centre of Health Statistics; 0.5% for 18-44 years, 4.7% for 45-64 years, 11% for 65-74 years and 19.5% for >75 years. A random-effects model was used to compare CAD prevalence in survivors and controls.

Results: Twenty studies (736,956 survivors) involved 17 types of cancer (bladder, breast, colorectal, hematologic, head and neck, kidney, liver, lung, melanoma, ovarian, pancreatic, prostate, renal, stomach, testicular, thyroid, uterus). Survivors overall were associated with an increased risk of CAD compared to controls (risk difference = 0.11, 95% CI: 0.07-0.15, p=0.0, I2=99.93%). Eight cancer types (breast, hematologic, head and neck, kidney, liver, pancreatic, stomach, and testicular) resulted in a significantly higher CAD compared to other cancer types (Figure).

Conclusions: Cancer survivors are at an increased risk of CAD compared to general population, but certain cancer types associate with a significantly higher CAD risk.
