Patient Preference and Adherence
|September 9, 2015
Summary
Patients with heart failure (HF) prioritize symptom relief, especially dyspnea, over other factors. Understanding these patient preferences is key to improving their health-related quality of life (HRQoL).
Area of Science:
- Cardiology
- Health Services Research
- Patient-Reported Outcomes
Background:
- Heart failure (HF) significantly impacts patients' quality of life, leading to frequent hospitalizations and high mortality.
- Optimizing HF management requires a deep understanding of patient preferences and priorities.
Purpose of the Study:
- To assess patient preferences for different aspects of heart failure management using conjoint analysis.
- To evaluate health-related quality of life (HRQoL) in heart failure patients.
Main Methods:
- A two-module approach was used: qualitative in-depth interviews (n=12) and a quantitative conjoint exercise (n=300).
- Patients completed the EuroQol health questionnaire (EQ-5D™) to measure HRQoL.
- Conjoint analysis presented patients with 10 different HF management scenarios.
Main Results:
- Dyspnea was the most critical attribute (44% importance), followed by physical capacity (18%), mental exhaustion (13%), HF-related fear (13%), and autonomy (12%).
- The EQ-5D™ revealed significant issues with anxiety/depression (23%), pain/discomfort (19%), and usual activities (15%).
- Stable, chronic HF patients reported better HRQoL (average EQ-5D score 0.39) than those recently hospitalized.
Conclusions:
- Conjoint analysis effectively captured patient preferences in heart failure.
- Preference weights derived from this study can inform the development of more patient-centered HRQoL assessment tools for HF care.

01:22Heart Failure Drugs: β-Blockers
1.2K
β-adrenergic antagonists, commonly known as β-blockers, block the effects of sympathetic neurotransmitters such as noradrenaline (NA) and adrenaline (ADR). They have several beneficial effects in heart failure treatment. They reduce heart rate, the force of contraction, and cardiac muscle relaxation. They also slow the atrial-ventricular conduction rate and raise the threshold for arrhythmias. The concentration of β-blockers determines their effects on bronchodilation,...

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.

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,...

01:26Heart 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...

1.9K
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...
