ESRD After Heart Failure, Myocardial Infarction, or Stroke in Type 2 Diabetic Patients With CKD

Area of Science:

• Nephrology
• Cardiology
• Diabetology

Background:

• The impact of cardiovascular (CV) events on the progression to end-stage renal disease (ESRD) in type 2 diabetes patients is not fully understood.
• Understanding this relationship is crucial for developing targeted interventions.

Purpose of the Study:

• To investigate the association between postrandomization cardiovascular events and the risk of developing ESRD.
• To analyze the characteristics of patients who develop ESRD following a cardiovascular event.

Main Methods:

• An observational study analyzing data from 4,022 patients with type 2 diabetes, anemia, and chronic kidney disease from the TREAT trial.
• Examined the incidence of ESRD and post-ESRD mortality following intercurrent cardiovascular events (e.g., heart failure, myocardial infarction, stroke).

Main Results:

• 23.8% of ESRD cases occurred after a cardiovascular event, with heart failure being the most common preceding event (16.9%).
• The ESRD rate was significantly higher within 30 days following a CV event (HR, 22.2).
• Patients developing ESRD post-CV event were older, had more prior CV disease, and higher baseline estimated glomerular filtration rates (eGFRs).

Conclusions:

• Intercurrent cardiovascular events, particularly heart failure, are strongly linked to an increased risk of ESRD in this population.
• Despite this association, most ESRD cases occurred in patients without preceding CV events.
• The findings highlight the need for kidney-specific therapies alongside cardiovascular risk factor management to reduce ESRD incidence in diabetes.
