Objective: To ensure compliance with optimal secondary prevention strategies and document the residual risk of patients following revascularization, we established a postrevascularization clinic for risk-factor optimization at 1 year, with outcomes recorded in a web-based registry. Although coronary revascularization can reduce ischemia, medical treatment of coronary artery disease (CAD) remains the cornerstone of ongoing risk reduction. While standardized referral pathways and protocols for revascularization are prevalent and well studied, post-revascularization care is often less formalized., Patients and Methods: The University of Ottawa Heart Institute is a tertiary-care center providing coronary revascularization services. From 2015 to 2019, data were prospectively recorded in the CAPITAL revascularization registry, and patient-level procedural, clinical, and outcome data are collected in the year following revascularization. Major adverse cardiovascular event (MACE) was defined as death, myocardial infarction, unplanned revascularization, or cerebrovascular accident. Kaplan-Meier curves were generated to evaluate time-to-event data for clinical outcomes by risk-factor management, and comparisons were performed using log-rank tests and reported by hazard ratio (HR) and 95% confidence intervals (CIs)., Results: A cohort of 4147 patients completed 1-year follow-up after revascularization procedure that included 3462 undergoing percutaneous coronary intervention (PCI), 589 undergoing coronary artery bypass graft (CABG), and 96 undergoing both PCI and CABG. In the year following revascularization (median follow-up 13.3 months-interquartile range [IQR]: 11.9-16.5) 11% of patients experienced MACE, with female patients being disproportionately at risk. Moreover, 47.7% of patients had ≥2 risk factors (diabetes, dyslipidemia, overweight, active smoker) at the time of follow-up, with 45.0% of patients with diabetes failing to achieve target hemoglobin (Hb) A1c, 54.8% of smokers continuing to smoke, and 27.1% of patients failing to achieve guideline-directed lipid targets., Conclusion: Patients who have undergone revascularization procedures remain at elevated risk for MACE, and inadequately controlled risk factors are prevalent in follow-up. This highlights the need for aggressive secondary prevention strategies and implementation of programs to optimize postrevascularization care., (© 2021 THE Authors.)

Diagnosis of acute and late cardiotoxicity from cancer therapeutics has become increasingly important as the scope of cardio-oncology increases exponentially, both in terms of the number of people affected and the types of therapies it encompasses. Cardiac magnetic resonance (CMR) is a tool that can offer unparalleled diagnostic information compared with other imaging modalities, but its utilization is often delayed, at the expense of patient care, due to the need for insurance pre-authorization. This paper highlights situations in which CMR is preferred as the diagnostic modality and provides examples of diagnoses more likely to be approved by insurance companies. It also provides specific cardio-oncology diagnoses or questions to help the clinical cardio-oncologist navigate the pre-authorization process., Competing Interests: Dr O’Quinn has received consulting fees for educational endeavors from AstraZeneca and Bracco.

Objectives: This study will compare the incidence of major adverse cardiovascular events (MACEs) with androgen deprivation therapy (ADT) among men with advanced prostate cancer who are being treated with a gonadotropin-releasing hormone (GnRH) antagonist versus a GnRH agonist., Background: Treatment of advanced prostate cancer with ADT might increase the risk of subsequent cardiovascular events among men with known atherosclerotic cardiovascular disease (ASCVD), but a recent meta-analysis suggested that this risk might be lower with ADT using a GnRH antagonist versus a GnRH agonist., Methods: PRONOUNCE is a multicenter, prospective, randomized, open, blinded endpoint trial that will enroll approximately 900 patients with advanced prostate cancer and pre-existing ASCVD who will be treated with ADT. Participants will be randomized to receive the GnRH antagonist degarelix or the GnRH agonist leuprolide as ADT for 12 months. The primary endpoint is time from randomization to first confirmed, adjudicated occurrence of a MACE, which is defined as a composite of all-cause death, nonfatal myocardial infarction, or nonfatal stroke through 12 months of ADT treatment. Baseline cardiovascular biomarkers (high-sensitivity C-reactive protein, high-sensitivity troponin T, and N-terminal pro-brain natriuretic peptide), as well as serial inflammatory and immune biomarkers, will be evaluated in exploratory analyses., Results: As of October 1, 2019, a total of 364 patients have been enrolled. The mean age is 74 years, 90% are white, 80% have hypertension or dyslipidemia, 30% diabetes mellitus, 40% have had a previous myocardial infarction, and 65% have had previous revascularization. Regarding prostate cancer features at randomization, 48% of the patients had localized disease, 23% had locally advanced disease, and 18% had metastatic disease., Conclusions: PRONOUNCE is the first prospective cardiovascular outcomes trial in advanced prostate cancer that will delineate whether the risk of subsequent cardiovascular events associated with ADT is lower with a GnRH antagonist versus a GnRH agonist for men with pre-existing ASCVD.
