Caregiver Strain and Heart Failure Patient Clinical Event Risk: An Extension of Previous Work
The Journal of Cardiovascular Nursing
|March 30, 2020
Summary
Greater caregiver strain in heart failure patients was linked to reduced clinical events, though variability necessitates further study. This finding supports caregiver support in heart failure management.
Area of Science:
- Cardiology
- Gerontology
- Nursing
Background:
- A previous study in Italian heart failure patient-caregiver dyads indicated that increased caregiver strain correlated with a lower risk of patient clinical events.
- This secondary analysis aimed to validate these findings within a United States-based cohort.
Purpose of the Study:
- To investigate the association between caregiver strain and clinical event risk in a US sample of heart failure patient-caregiver dyads.
- To determine if the protective effect of caregiver strain on patient outcomes observed in an Italian cohort is replicated in a US population.
Main Methods:
- The study analyzed data from 92 dyads participating in a self-care intervention.
- Logistic regression modeled the relationship between baseline caregiver strain (measured by the Bakas Caregiving Outcomes Scale) and patient events (hospitalization, emergency visits, or mortality) over 8 months.
Main Results:
- Almost half of the patients (43.5%) experienced a clinical event during the 8-month follow-up.
- High caregiver strain was significantly associated with a 92.7% reduction in event risk compared to low strain (odds ratio, 0.07; P = .02).
- A notable degree of variability was observed in this association.
Conclusions:
- The findings partially corroborated the Italian study, suggesting a potential link between caregiver strain and reduced patient event risk in the US.
- The substantial variability and divergence from other research highlight the complexity of this relationship.
- Further investigation is warranted to understand the nuances and implications of caregiver strain in heart failure management.

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,...

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...

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...

01:27Heart Failure I: Introduction
612
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...
