Insights

Reduced left ventricular ejection fraction (LVEF) increases risks for patients undergoing percutaneous coronary intervention (PCI). This includes higher risks of death and myocardial infarction, regardless of chronic kidney disease (CKD) status.

Area of Science:

  • Cardiology
  • Nephrology
  • Interventional Cardiology

Background:

  • Reduced left ventricular ejection fraction (LVEF) is a known risk factor for adverse outcomes post-percutaneous coronary intervention (PCI).
  • The prognostic impact of reduced LVEF in patients with chronic kidney disease (CKD) undergoing PCI is not well-established.
  • CKD is increasingly prevalent and associated with cardiovascular complications.

Purpose of the Study:

  • To investigate the impact of reduced LVEF on major adverse cardiovascular events (MACE) in patients with and without CKD undergoing PCI.
  • To stratify risks associated with reduced LVEF in the context of CKD and PCI.
  • To determine if CKD modifies the effect of reduced LVEF on PCI outcomes.

Main Methods:

  • A retrospective analysis of 12,353 patients who underwent PCI between 2012 and 2023.
  • Patients were categorized based on the presence of CKD (eGFR <60 mL/min/1.73 m²) and reduced LVEF (<50%).
  • The primary endpoint was MACE (all-cause death, MI, or target vessel revascularization) at 1 year post-PCI.

Main Results:

  • Among 3,199 CKD patients, 23.5% had reduced LVEF. Reduced LVEF was associated with higher prevalence of advanced atherosclerosis and comorbidities.
  • No significant difference in MACE was observed between CKD patients with reduced versus normal LVEF (HR 1.18, P = .23).
  • However, reduced LVEF in CKD patients was linked to significantly higher risks of all-cause death (HR 1.85, P < .05) and MI (HR 1.78, P < .05). Non-CKD patients also showed increased risks.

Conclusions:

  • Reduced LVEF is associated with increased risks of death and myocardial infarction after PCI, irrespective of CKD status.
  • The findings suggest that reduced LVEF is an independent risk factor for adverse cardiovascular events in patients undergoing PCI.
  • Close monitoring and risk stratification are warranted for patients with reduced LVEF, especially those with CKD, undergoing PCI.

Cardiac Catheterization I: Pre-Procedure Overview

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Nursing management is essential for preventing complications, maintaining stability, and improving patients' quality of life in chronic kidney disease (CKD). By using a structured approach, nurses help slow CKD progression and support effective patient care​.1. Comprehensive patient assessmentEffective management begins with nurses reviewing the patient’s medical history, and identifying key risk factors like diabetes, hypertension, and nephrotoxic drug use. Nurses assess signs of...

Heart Failure Drugs: Diuretics

Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...
