Insights

Congestive heart failure (CHF) patients with preserved ejection fraction (≥ 45%) show similar long-term mortality and morbidity compared to those with reduced ejection fraction. Clinical characteristics differ, but outcomes are comparable.

Area of Science:

  • Cardiology
  • Heart Failure Research

Background:

  • Limited data exists on clinical features, treatment, and prognosis for congestive heart failure (CHF) with preserved left ventricular ejection fraction (LVEF).
  • Existing study results on this patient group are often conflicting.

Purpose of the Study:

  • To investigate the clinical characteristics of patients diagnosed with CHF and preserved LVEF (≥ 45%).
  • To determine the long-term prognosis and outcomes for patients with CHF and preserved LVEF.

Main Methods:

  • Prospective, multicenter study involving 4720 patients across 62 heart failure clinics in Spain (BADAPIC registry, 1999-2003).
  • Analysis of patient demographics, clinical features, and follow-up data over a mean of 40 months.
  • Multivariate analysis to identify independent predictors of mortality.

Main Results:

  • 30% of CHF patients in the registry had preserved LVEF.
  • Patients with preserved LVEF were older, more frequently female, and had higher rates of atrial fibrillation, hypertension, and non-ischemic cardiomyopathy.
  • Mortality and cardiovascular complication rates were similar between preserved and reduced LVEF groups.
  • Ejection fraction was not an independent predictor of mortality; 1- and 5-year survival rates were comparable.

Conclusions:

  • A significant proportion of heart failure patients present with preserved LVEF.
  • Despite distinct clinical profiles, patients with preserved LVEF experience similar morbidity and mortality rates compared to those with reduced LVEF.

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 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...

Heart Failure IV: Classification and Diagnostic Evaluation

Heart failure can be classified in various ways, with the most common classifications based on physical activity limitations, disease progression, severity, and treatment strategies.The Functional Classification of Heart Failure divides patients into four categories based on physical activity limitation due to symptom burden.Class I: Patients in this class have cardiac disease but no physical activity limitations. Ordinary activities like walking, climbing stairs, or routine tasks do not cause...

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 Failure01:17

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...
