BACKGROUND: Androgen deprivation therapy for prostate cancer is known to increase the risk of cardiovascular disease, but there is controversy regarding the cardiovascular risk in patients with preexisting cardiovascular disease. This study assessed the risk of cardiovascular intervention after androgen deprivation therapy in patients with a history of cardiovascular disease, cerebrovascular disease, and cardiovascular intervention.
MATERIALS AND METHODS: Between 2008 and 2017, 195,308 men with newly diagnosed prostate cancer were identified from the nationwide claims database in South Korea. Among them, 49,090 men with a history of ischemic cardiovascular and cerebrovascular diseases were analyzed. The patients were divided into the androgen deprivation therapy (n = 14,092) and non-androgen deprivation therapy (n = 34,988) groups. The primary outcome was cardiovascular interventions (percutaneous transluminal angioplasty and coronary bypass surgery). Cox proportional hazard regression models were used to estimate the adjusted hazard ratios and 95% confidence intervals of the events.
RESULTS: After balancing the covariates with 1:1 exact matching, the two groups had 10,514 subjects each. Multivariable analysis demonstrated that androgen deprivation therapy was not significantly associated with an increased risk of cardiovascular interventions (hazard ratio, 1.060; 95% confidence interval, 0.923-1.217; P = 0.4104), regardless of the duration of therapy. A history of cardiovascular intervention, diabetes mellitus, antithrombotic medication use, and cardiovascular events significantly increased the risk of cardiovascular intervention.
CONCLUSIONS: Androgen deprivation therapy was not associated with cardiovascular intervention in patients with a previous history of cardiovascular disease, regardless of the duration of therapy. Therefore, the cardiovascular risk of androgen deprivation therapy should be reassessed in this population.
