Cardiovascular Considerations Before Cancer Therapy: Gaps in Evidence and Expert Panel Recommendations.

Baseline cardiovascular assessment before the initiation of potentially cardiotoxic cancer therapies is a key component of cardio-oncology, aiming to reduce cardiovascular complications and morbidity in patients and survivors. Recent clinical practice guidelines provide both general and cancer therapy-specific recommendations for baseline cardiovascular toxicity risk assessment and management, including the use of dedicated risk scores, cardiovascular imaging, and biomarker testing. However, the value of such interventions in altering disease trajectories has not been established, with many recommendations based on expert opinion or Level of Evidence: C, studies with a potential for high risk of bias. Advances in understanding underlying mechanisms of cardiotoxicity and the increased availability of genetic and immunologic profiling present new opportunities for personalized risk assessment. This paper evaluates the existing evidence on cardiovascular care of cancer patients before cardiotoxic cancer therapy and highlights gaps in evidence and priorities for future research.
