Death and dying in heart failure with normal ejection fraction

|October 21, 2009
Summary
Mortality rates for heart failure with normal ejection fraction (HFNEF) mirror those with reduced ejection fraction, but treatments targeting neurohumoral pathways haven't improved survival in HFNEF patients. Identifying high-risk HFNEF individuals is crucial for effective therapy.
Area of Science:
- Cardiology
- Heart Failure Research
- Clinical Trials
Background:
- Patients with heart failure with normal ejection fraction (HFNEF) exhibit mortality rates comparable to those with heart failure with reduced ejection fraction (HFrEF).
- Randomized trials investigating neurohumoral blockade in HFNEF have not shown significant reductions in mortality.
- A lower proportion of heart failure-related deaths contributes to the challenges in demonstrating treatment efficacy in HFNEF.
Discussion:
- The comparable mortality rates between HFNEF and HFrEF suggest similar underlying disease severity.
- The failure of neurohumoral blockade therapies, effective in HFrEF, highlights distinct pathophysiological mechanisms in HFNEF.
- Understanding the specific causes of death in HFNEF is critical for developing targeted treatment strategies.
Key Insights:
- HFNEF patients face similar overall mortality risks as HFrEF patients.
- Current neurohumoral blockade treatments lack efficacy in reducing mortality for HFNEF.
- Identifying HFNEF subgroups at higher risk for heart failure-related death is a key research priority.
Outlook:
- Future research should focus on better characterizing HFNEF patients at greatest risk for heart failure-specific mortality.
- Investigating the diverse modes of death in HFNEF is essential for tailoring medical and device therapies.
- Developing targeted therapeutic approaches based on distinct HFNEF pathophysiology could improve patient outcomes.

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 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 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 VII: Nursing Interventions
The first step in nursing management of a patient with heart failure involves thoroughly assessing the patient's medical history.Subjective Data: Obtain the patient's medical history of coronary artery disease, hypertension, myocardial infarction, and symptoms like dyspnea, orthopnea, and paroxysmal nocturnal dyspnea.Objective Data: Conduct a physical examination to identify findings such as jugular vein distention, pulmonary crackles, tachycardia, murmurs, peripheral edema, and vital signs,...
Cardiomyopathy II: Dilated Cardiomyopathy
Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...
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...
