Insights

Individuals with familial hypercholesterolemia (FH) have higher risks of peripheral arterial disease (PAD) and chronic kidney disease (CKD). Low ankle-brachial index (ABI) and estimated glomerular filtration rate (eGFR) indicate a greater risk of myocardial infarction.

Area of Science:

  • Cardiovascular Medicine
  • Nephrology
  • Genetics

Background:

  • Familial hypercholesterolemia (FH) significantly increases coronary artery disease risk.
  • The association of FH with peripheral arterial disease (PAD) and chronic kidney disease (CKD) remains unclear.

Purpose of the Study:

  • To investigate elevated risks of PAD and CKD in individuals with clinical FH.
  • To determine if low ankle-brachial index (ABI) and estimated glomerular filtration rate (eGFR) correlate with myocardial infarction risk in FH patients.

Main Methods:

  • Prospective cohort study involving 106,172 individuals, with 7,109 diagnosed with FH.
  • Analysis of associations between FH, PAD, CKD, and myocardial infarction.
  • Utilized multivariable adjusted odds ratios (ORs) and hazard ratios (HRs) with 95% confidence intervals (CIs).

Main Results:

  • FH patients showed significantly higher ORs for PAD (1.84-1.36) and CKD (1.92-2.42) compared to controls.
  • Low ABI (≤0.9) in FH patients was associated with a 4.60-fold increased risk of myocardial infarction.
  • Low eGFR (<60 mL/min/1.73 m2) in FH patients correlated with a 2.19-fold increased risk of myocardial infarction.

Conclusions:

  • Clinical FH is linked to increased risks of PAD and CKD.
  • Low ABI and eGFR serve as important prognostic indicators for myocardial infarction in FH individuals.
  • Screening for PAD and CKD, alongside ABI and eGFR monitoring, is recommended for managing FH patients at high cardiovascular risk.

Chronic Kidney Disease I: Introduction

Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...

Peripheral Artery Disease I: Introduction

Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

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...

Chronic Kidney Disease IV: Nursing Management

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...
