Review article: Coronary artery stenoses: detection and revascularization in renal disease

Area of Science:

• Cardiology
• Nephrology
• Vascular Medicine

Background:

• Cardiovascular events are significantly increased in individuals with renal impairment.
• Established coronary artery disease (CAD) management guidelines exist for the general population but not for renal patients.
• Kidney disease necessitates specialized approaches to cardiovascular care.

Purpose of the Study:

• To review current literature on detecting coronary artery stenoses in patients with kidney disease.
• To summarize the outcomes of revascularization procedures for these patients.
• To inform clinical practice regarding CAD management in renal impairment.

Main Methods:

• Systematic review of published research on coronary artery disease detection and revascularization in kidney disease.
• Analysis of outcomes based on renal function, dialysis status, and transplantation.

Main Results:

• Coronary artery disease testing is common in dialysis patients awaiting transplantation.
• Positive stress tests correlate with increased cardiac event risk, but testing benefits post-transplant are unclear.
• Revascularization generally has higher morbidity/mortality in kidney disease, except for transplant recipients.
• Coronary artery bypass surgery appears more beneficial than percutaneous intervention for dialysis patients and post-transplant.

Conclusions:

• Limited data supports intervention for asymptomatic CAD before transplantation.
• Coronary artery bypass surgery may be preferred over percutaneous intervention in specific kidney disease populations.
• Further research is needed to establish clear guidelines for CAD management in renal impairment.
