Summary
Increasing physical activity (PA) intensity in heart failure (HF) patients with implantable cardioverter defibrillators (ICDs) improved psychological symptoms and reduced fatigue. Changes in PA volume did not significantly impact symptoms.
Area of Science:
- Cardiology
- Exercise Physiology
- Psychology
Background:
- Limited understanding of how physical activity (PA) changes affect heart failure (HF) symptoms.
- Investigating the relationship between PA modifications and symptom burden in HF patients.
Purpose of the Study:
- To examine the association between changes in physical activity (PA) and physical/psychological symptoms in heart failure (HF) patients with implantable cardioverter-defibrillators (ICDs).
Main Methods:
- Secondary analysis of a randomized controlled trial (RCT) involving 96 HF patients with ICDs.
- PA (steps/day and intensity) and symptoms (fatigue, pain, depression, anxiety) measured at baseline and 2 months.
- Multivariate regression analyzed associations between PA changes and symptom outcomes.
Main Results:
- Increased PA intensity correlated with reduced depression, anxiety, and fatigue.
- Increased PA volume (steps) was linked to improved anxiety.
- Decreased PA volume or intensity showed no significant association with symptom changes.
Conclusions:
- Higher intensity PA over 2 months improved psychological well-being and reduced fatigue in HF patients with ICDs.
- Interventions focusing on increasing PA intensity may effectively manage certain HF symptoms.
- PA volume changes did not demonstrate a significant impact on symptom profiles.

Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

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,...

1.5K
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...

Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.
Sustained exercise increases the muscles' oxygen demand, which can be...

2
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...
