    Insights

    Patients with chronic kidney disease (CKD) face higher risks of severe cardiovascular disease. This study examines how undertreatment, or therapeutic nihilism, contributes to these poor outcomes, suggesting improved treatment access can enhance patient health.

    Area of Science:

    • Nephrology
    • Cardiology
    • Clinical Medicine

    Background:

    • Patients with renal dysfunction exhibit increased rates of premature, severe, complicated, and fatal cardiovascular disease compared to those with normal renal function.
    • Four primary explanations exist: confounding variables (diabetes, hypertension), therapeutic nihilism, increased therapy toxicities, and CKD-driven biological factors promoting cardiovascular disease.

    Purpose of the Study:

    • To investigate the contribution of treatment disparities, specifically therapeutic nihilism, to adverse outcomes in patients with acute coronary syndromes and acutely decompensated heart failure.
    • To highlight the importance of overcoming barriers to beneficial treatment utilization for improving clinical outcomes in this patient population.

    Main Methods:

    • Review and analysis of existing literature and clinical observations regarding treatment patterns and outcomes in patients with chronic kidney disease (CKD) and cardiovascular conditions.
    • Focus on the specific subset of patients experiencing acute coronary syndromes and acutely decompensated heart failure.

    Main Results:

    • Therapeutic nihilism, or the underuse of evidence-based therapies in patients with CKD, is a significant contributor to poorer cardiovascular outcomes.
    • These treatment disparities exacerbate the inherent risks associated with renal dysfunction, leading to more severe and fatal cardiovascular events.

    Conclusions:

    • Addressing and overcoming therapeutic nihilism in CKD patients is crucial for improving cardiovascular health.
    • Facilitating access to and utilization of beneficial therapies can mitigate the heightened risk of cardiovascular disease in patients with impaired renal function.

    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...

    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...

    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...
