Coronary Revascularization in High-Risk Stable Patients With Significant Comorbidities: Challenges in Decision-Making
- 8 Downloads
Purpose of review
There is a growing cohort of complex high-risk patients with stable ischemic heart disease (SIHD) who present for coronary artery bypass graft (CABG) surgery and percutaneous coronary intervention (PCI). These patients are older, have complex coronary disease, and a substantial comorbidity burden including frailty. The procedural risks and outcomes of CABG and PCI in these patients are more difficult to assess based on the available literature, which has generally studied a younger population with a lower comorbidity burden.
There have been initiatives to recalibrate and expand risk models derived from procedural registries to inform the care of complex higher-risk patients, including patients “turned down” for CABG. There is greater recognition of the need for improved assessment of risk, quality, and benefits of coronary revascularization in higher-risk SIHD patients with a substantial comorbidity burden.
Clinicians and patients should be aware that there are significant evidence gaps regarding revascularization in complex high-risk patients. The limitations of procedural-derived risk scores should be understood when presenting treatment options. Future randomized controlled trials and expanded registries are greatly desired and should be achievable. Meanwhile, a multidisciplinary heart team approach should be employed for proper decision-making.
