A Personalized Approach to Chronic Kidney Disease and Cardiovascular Disease: JACC Review Topic of the Week

Area of Science:

• Nephrology
• Cardiology
• Medical Imaging

Background:

• Cardiovascular disease (CVD) is the leading cause of mortality in end-stage renal disease (ESRD) patients.
• Dialysis initiation in ESRD exacerbates hemodynamic and electrolyte imbalances, contributing to cardiac complications.
• Existing risk models inadequately predict cardiovascular mortality in chronic kidney disease (CKD).

Purpose of the Study:

• To review the cardiovascular risks associated with hemodialysis.
• To explore the pathophysiology of cardiovascular complications in CKD patients undergoing dialysis.
• To examine the role of multimodality imaging in prognostication and risk stratification for these patients.

Main Methods:

• Comprehensive literature review of cardiovascular risks in ESRD and dialysis.
• Discussion of pathophysiological mechanisms linking kidney disease, dialysis, and cardiac events.
• Exploration of multimodality imaging techniques for risk assessment.

Main Results:

• Hemodialysis initiation causes significant fluid and electrolyte shifts, leading to subendocardial ischemia, left ventricular hypertrophy, and diastolic dysfunction.
• These perturbations increase the incidence of acute coronary syndrome and sudden cardiac death in CKD patients.
• Multimodality imaging presents a promising avenue for improved risk stratification and personalized patient management.

Conclusions:

• Cardiovascular complications are a major concern for ESRD patients on dialysis, driven by unique pathophysiological processes.
• Novel applications of multimodality imaging are crucial for enhancing prognostication and guiding personalized treatment strategies.
• Further research integrating imaging into risk prediction models is warranted for better patient outcomes.
