Coronary revascularization in patients with end-stage renal disease: risks, benefits, and optimal strategies

Area of Science:

• Nephrology
• Cardiology
• Clinical Medicine

Background:

• Patients with end-stage renal disease (ESRD) face elevated cardiac mortality risks.
• Coronary artery disease (CAD) in ESRD patients is often managed conservatively, lacking robust trial data.
• Existing evidence relies on retrospective analyses of limited patient cohorts.

Purpose of the Study:

• To evaluate whether medical therapy or mechanical revascularization is superior for ESRD patients with CAD.
• To determine the optimal mechanical revascularization approach: surgical versus percutaneous coronary intervention.
• To highlight the need for high-quality, prospective data in this high-risk population.

Main Methods:

• Review of existing literature and databases concerning CAD management in ESRD patients.
• Analysis of retrospective data to assess outcomes of conservative versus revascularization strategies.
• Comparison of surgical versus percutaneous revascularization outcomes in ESRD patients with significant CAD.

Main Results:

• Mortality data suggest a benefit for coronary revascularization in ESRD patients with significant CAD.
• Current evidence supporting revascularization is primarily from retrospective studies with small sample sizes.
• No definitive data exist to favor medical therapy over mechanical revascularization or one revascularization technique over another.

Conclusions:

• Coronary revascularization appears beneficial for ESRD patients with significant CAD, though evidence is limited.
• Individualized treatment decisions are necessary, considering patient comorbidities and coronary anatomy.
• Large-scale, prospective, randomized controlled trials are critically needed to guide optimal revascularization strategies in ESRD.
