Introduction: Androgen receptor targeted agents (ARTA) have increasingly been incorporated into treatment regimens for various stages of prostate cancer. Patients are living longer with prostate cancer, and thus have a higher cumulative exposure to the treatment and its accompanying side effects, especially those of cardiovascular disease. We aim to assess the differences in the incidence of cardiac-related adverse events after treatment of prostate cancer with ARTA versus placebo.
Methods: Three databases were thoroughly searched for relevant articles. The PICOS model was used to frame our clinical question, with which 2 independent authors went through several rounds of screening to select the final included studies. Meta-analysis was done using the Cochran-Mantel-Haenszel Method. Quality assessment was carried out with the Cochrane Risk of Bias tool RoB 2.
Results: The use of ARTA in prostate cancer increases the incidence of cardiac-related adverse events (RR: 1.56, 95% CI: 1.29-1.90, p < 0.00001), such as hypertension (RR: 1.69, 95% CI: 1.46-1.97, p < 0.00001), ischaemic heart disease (RR: 1.84, 95% CI: 1.36-2.50, p < 0.0001), and arrhythmia (RR: 1.38, 95% CI: 1.11-1.71, p = 0.004), although this did not manifest in an increased incidence of cardiac arrests/deaths (RR: 1.28, 95% CI: 0.87-1.88, p = 0.21).
Discussion: ARTA increases the risk of cardiac-related adverse events, hypertension, ischaemic heart disease and arrhythmia. Armed with this knowledge, we will be better poised to manage cardiac risks accordingly and involve a cardiologist as required when starting patients on ARTA.
