Insights

Congestive heart failure (CHF) increases mortality risk in patients undergoing hip surgery for femoral neck fractures. Hemiarthroplasty may be a safer option than total hip arthroplasty for patients with moderate to severe CHF.

Area of Science:

  • Orthopedic Surgery
  • Cardiology
  • Public Health

Background:

  • Total hip arthroplasty (THA) is preferred for femoral neck fractures, but congestive heart failure (CHF) poses a significant mortality risk.
  • The impact of CHF severity on mortality following THA versus hemiarthroplasty for femoral neck fractures requires further investigation.

Purpose of the Study:

  • To evaluate the association between congestive heart failure (CHF) severity and 30-day postoperative mortality after total hip arthroplasty (THA) and hemiarthroplasty for acute femoral neck fractures.
  • To compare the mortality risks associated with THA and hemiarthroplasty in patients with varying degrees of CHF.

Main Methods:

  • Retrospective cohort study using the National Surgical Quality Improvement database.
  • Inclusion of patients treated for acute, closed, intracapsular femoral neck fractures.
  • Stratification of patients based on New York Heart Association (NYHA) CHF categories (mild, moderate, severe) and surgical procedure (THA vs. hemiarthroplasty).

Main Results:

  • Overall 30-day mortality was 2.1% for THA and 5.4% for hemiarthroplasty.
  • Mortality increased with CHF severity for both procedures.
  • Patients with mild and moderate CHF undergoing THA had significantly higher adjusted odds ratios for 30-day mortality compared to hemiarthroplasty.

Conclusions:

  • Congestive heart failure (CHF) is associated with increased 30-day mortality after total hip arthroplasty (THA) for femoral neck fractures, indicating CHF is not a modifiable risk factor in this context.
  • Hemiarthroplasty presents a potentially safer surgical option for patients with congestive heart failure (CHF) undergoing treatment for femoral neck fractures, given the observed mortality trends.

Heart Failure II: Pathophysiology

Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

Heart Failure I: Introduction

Heart failure refers to a clinical syndrome caused by structural or functional cardiac disorders that prevent the heart from pumping an adequate amount of blood to meet the body's metabolic needs. This condition often arises from myocardial infarction or ischemia, leading to decreased cardiac output, reduced tissue perfusion, impaired gas exchange, fluid volume imbalance, and decreased functional ability.Heart failure can result from disruptions in the mechanisms that regulate cardiac output...

Pathophysiology of Heart Failure

Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Heart Failure III: Clinical Manifestations

Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...
