Heart Failure V: Medical Management

16
Medical Management of Acute Decompensated Heart Failure (ADHF)The primary goals of therapy for patients hospitalized with acute decompensated heart failure (ADHF) include:Relieving symptomsOptimizing volume statusSupporting oxygenation and ventilationMaintaining cardiac output (CO) and end-organ perfusionIdentifying and addressing the cause of ADHFPreventing complicationsProviding patient education on factors precipitating HF exacerbationPlanning for dischargeOngoing monitoring and assessment...

Heart Failure VII: Nursing Interventions

127
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

12
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,...

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: Inhibitors of Renin-Angiotensin System01:26

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

473
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...

Area of Science:

  • Digital Health
  • Cardiovascular Research
  • Behavioral Science

Background:

  • Heart failure (HF) is a leading cause of hospitalization in older adults, with significant disparities in outcomes.
  • Poor adherence to self-management behaviors, such as daily weight monitoring and physical activity, negatively impacts HF outcomes.
  • Sensor-controlled digital games (SCDGs) offer a promising, scalable approach to motivate and monitor these behaviors in real-world contexts.

Purpose of the Study:

  • To assess the efficacy of an SCDG in improving adherence to HF self-management behaviors.
  • To integrate behavioral data from weight scales and activity trackers to drive game progress, rewards, and feedback.
  • To evaluate the impact of SCDGs on both proximal (behavioral) and distal (clinical) HF outcomes.

Main Methods:

  • A randomized clinical trial involving 200 participants (≥45 years) with HF.
  • Participants were randomized into an SCDG playing group (intervention) or a sensor-only group (control).
  • Outcomes, including self-management behaviors and HF hospitalizations, were measured at baseline and at 6, 12, and 24 weeks.

Main Results:

  • Recruitment began in November 2022, with completion expected in Q1 2025.
  • Full study results and data are anticipated for publication in 2026.
  • The study is powered to detect differences in daily weight monitoring between groups.

Conclusions:

  • This project will provide insights into scalable, user-friendly digital gaming solutions for heart failure self-management.
  • The findings aim to guide the development of interventions that promote sustained adherence to self-management behaviors.
  • The study seeks to improve health outcomes for individuals living with heart failure through innovative digital technology.
