Abstract Background Cancer therapies have prolonged survival in lymphoma. However, lymphoma patients may develop significant coronary artery disease (CAD), which may be treated by percutaneous coronary intervention (PCI). The characteristics and outcomes of lymphoma patients treated by PCI are not well studied. Methods We reviewed lymphoma patients undergoing PCI at our institution between 2010 and 2020 and compared them to a cohort without cancer. Patient characteristics and predictors of long-term mortality and major adverse cardiac events (MACE) (death, myocardial infarction, target lesion revascularization) were studied using descriptive statistics and survival analysis utilizing a Cox proportional hazards model. Results Of the 11,953 patients in the study cohort, 83 had a history of lymphoma meeting study criteria. Lymphoma patients, as compared to non-lymphoma patients were similar with respect to age, sex, hypertension, diabetes, hyperlipidemia, prior MI, and prior PCI (all p=ns). Over a median follow-up of 3.9 (1.0, 5.0) years, the mortality at 5 years was higher in lymphoma versus non-lymphoma patients (47.5% vs 29.8%) (P=0.005) (Figure). After adjusting for age, sex, hypertension, diabetes, shock, smoking status, heart failure, and chronic renal disease, lymphoma was an independent predictor of mortality (OR 1.59; 95% CI 1.07-2.36, p=0.02). Lymphoma was not independently associated with MACE. Discussion Lymphoma patients undergoing PCI have significantly lower survival rates than non-cancer controls. After accounting for important cardiac risk factors, lymphoma was independently associated with higher long term mortality.
