Heart Failure VI: Adjunct Therapies

547
Additional therapies for treating patients with heart failure (HF) may include procedural interventions, supplemental oxygen, the management of sleep disorders, and nutritional therapy.Procedural InterventionsImplantable Cardioverter-Defibrillator: For patients at risk of life-threatening arrhythmias due to severe left ventricular dysfunction, an Implantable Cardioverter-Defibrillator (ICD) can detect and terminate these arrhythmias, preventing sudden cardiac death and improving survival rates.

Heart Failure Drugs: Inotropic Agents

1.8K
Positive inotropic agents are commonly used as the first line of treatment for heart failure. One such agent is digoxin, derived from the genus Digitalis, which has been known for centuries but effectively utilized since 1785. However, these cardiac glycosides can have potentially toxic effects due to their mechanism of action, which involves inhibiting Na+/K+-ATPase and increasing contractility. Digoxin is absorbed orally and distributed in various tissues, including the CNS. It has a long...

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System01:26

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

1.4K
The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

Heart Failure I: Introduction01:27

Heart Failure I: Introduction

1.2K
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...

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,...

    Area of Science:

    • Cardiology
    • Rehabilitation Medicine
    • Robotics in Medicine

    Background:

    • Heart failure (HF) patients often experience reduced exercise capacity and muscle weakness.
    • Traditional rehabilitation programs may not fully address the complex needs of HF patients.
    • Exploring novel therapeutic approaches is crucial for improving outcomes in HF management.

    Purpose of the Study:

    • To assess the feasibility and safety of robot-assisted gait therapy using the Lokomat® system in stable heart failure patients.
    • To evaluate the impact of this therapy on exercise capacity, muscle strength, and quality of life.
    • To investigate changes in cardiac and inflammatory biomarkers following the intervention.

    Main Methods:

    • A pilot study involving 5 stable heart failure patients (left ventricular ejection fraction < 45%).
    • A four-week intervention combining aerobic training with dynamic lower limb resistance training using the Lokomat® system.
    • Assessment of cardiac (NT-ProBNP) and inflammatory (hsCRP, IL6) biomarkers, cardiopulmonary exercise testing, quality of life scores, and quadriceps force.

    Main Results:

    • Robot-assisted gait therapy was feasible and safe, with no adverse events reported.
    • Significant improvements were observed in peak work rate (6-36%), peak quadriceps force (3-80%), and quality of life scores.
    • Three out of five patients showed increased peak oxygen consumption, and four out of five demonstrated improved oxygen pulse.
    • Cardiac biomarker NT-ProBNP and inflammatory markers (hsCRP, IL6) decreased in four out of five patients.

    Conclusions:

    • Robot-assisted gait therapy with the Lokomat® System is a safe and feasible intervention for heart failure patients.
    • The combined training approach demonstrated benefits in exercise capacity, muscle strength, and quality of life.
    • Improvements in cardiac and inflammatory biomarkers suggest a positive impact on cardiovascular health, warranting further investigation in larger trials.
