Coronary artery disease in uremia: Etiology, diagnosis, and therapy

Area of Science:

• Nephrology
• Cardiology
• Internal Medicine

Background:

• Cardiovascular disease (CVD) is the leading cause of mortality in kidney transplant recipients and a significant barrier to transplantation for dialysis patients.
• Coronary artery disease (CAD) in uremic patients exhibits distinct characteristics compared to non-uremic populations, complicating diagnosis and treatment.
• There is a limited evidence base for therapeutic interventions in CAD within the context of uremia.

Purpose of the Study:

• To review the current experimental and clinical literature on cardiovascular disease in uremia, with a specific focus on coronary artery disease.
• To examine the incidence, clinical presentations, diagnostic tools, and treatment strategies for CAD in patients with acute and chronic kidney disease.
• To evaluate recent evidence on interventions such as coronary angioplasty, stenting, and bypass surgery in renal failure patients.

Main Methods:

• Systematic review of experimental and clinical studies.
• Analysis of literature concerning incidence, syndromes, screening, and interventions for CAD in uremia.
• Review of comparative studies on revascularization procedures in patients with renal failure.

Main Results:

• Coronary artery disease is more prevalent and challenging to diagnose and treat in uremic individuals compared to the general population.
• Current therapeutic options for CAD in uremia are less effective, highlighting a need for more robust clinical trials.
• Evidence comparing percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) in renal failure patients is limited.

Conclusions:

• CAD in uremia is a complex issue requiring tailored management strategies.
• Aggressive control of both traditional and novel cardiovascular risk factors is crucial.
• Early intervention for symptomatic coronary artery disease is advised in the absence of definitive trial data.
