Approach to stable angina in patients with advanced chronic kidney disease

Area of Science:

• Nephrology
• Cardiology
• Clinical Trials

Background:

• Chronic kidney disease (CKD) is a significant risk factor for coronary artery disease (CAD).
• Patients with advanced CKD or end-stage renal disease (ESRD) often present atypically with CAD.
• Limited data exist on the evaluation and management of stable angina in advanced CKD patients.

Purpose of the Study:

• To review current data on the assessment and management of stable coronary artery disease (CAD) and stable angina.
• To extrapolate these findings to advanced chronic kidney disease (CKD) patients, particularly those awaiting kidney transplantation.

Main Methods:

• The ISCHEMIA-CKD trial, a large prospective randomized study, is a key focus.
• Comparison of an invasive strategy (percutaneous coronary intervention or coronary artery bypass graft) versus conservative medical management in advanced CKD patients with moderate to severe myocardial ischemia.

Main Results:

• The ISCHEMIA-CKD trial found no significant difference in the risk of death or nonfatal myocardial infarction between invasive and conservative strategies.
• An initial invasive strategy did not reduce the risk of death or nonfatal myocardial infarction compared to maximal medical management in this population.

Conclusions:

• For patients with advanced CKD and stable CAD, an invasive strategy offers no clear advantage over optimal medical therapy regarding major adverse cardiovascular events.
• Further research is needed to refine treatment guidelines for stable CAD in advanced CKD patients awaiting transplantation.
