In a survey of 429 US adults with heart failure, only 24.9% reported familiarity with angiotensin receptor-neprilysin inhibitors or mineralocorticoid receptor antagonists.
Cross-Sectional (n=429)
A significant proportion of patients with heart failure are unfamiliar with key GDMT classes like ARNIs and MRAs, and many have concerns about their safety and effectiveness, indicating a need for better patient education.
Importance: There are major gaps in use of guideline-directed medical therapy (GDMT) for patients with heart failure (HF). Patient-reported data outlining patient goals and preferences associated with GDMT are not available. Objective: To survey patients with chronic HF to better understand their experiences and perceptions of living with HF, including their familiarity and concerns with important GDMT therapies. Design, Setting, and Participants: Study participants were recruited from the GfK KnowledgePanel, a probability-sampled online panel representative of the US adult population. English-speaking adults who met the following criteria were eligible if they were (1) previously told by a physician that they had HF; (2) currently taking medications for HF; and (3) had no history of left ventricular assist device or cardiac transplant. Data were collected between October and November 2018. Analysis began in December 2018. Main Outcomes and Measures: The survey included 4 primary domains: (1) relative importance of disease-related goals, (2) challenges associated with living with HF, (3) decision-making process associated with HF medication use, and (4) awareness and concerns about available HF medications. Results: Of 30 707 KnowledgePanel members who received the initial survey, 15 091 (49.1%) completed the screening questions, 440 were eligible and began the survey, and 429 completed the survey. The median (interquartile range) age was 68 (60-75) years and most were white (320 74.6%), male (304 70.9%), and had at least a high school education (409 95.3%). Most survey responders reported familiarity with β-blockers, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, and diuretics. Overall, 107 (24.9%) reported familiarity with angiotensin receptor-neprilysin inhibitors or mineralocorticoid receptor antagonists. Overall, 136 patients (42.5%) reported have safety concerns regarding angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, and 133 (38.5%) regarding β-blockers, 35 (37.9%) regarding mineralocorticoid receptor antagonists, 38 (36.5%) regarding angiotensin receptor-neprilysin inhibitors, and 123 (37.2%) regarding diuretics. Between 27.7% (n = 26) and 38.5% (n = 136) reported concerns regarding the effectiveness of β-blockers, angiotensin receptor-neprilysin inhibitors, mineralocorticoid receptor antagonists, or diuretics, while 41% (n = 132) were concerned with the effectiveness of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers. Conclusions and Relevance: In this survey study, many patients were not familiar with GDMT for HF, with familiarity lowest for angiotensin receptor-neprilysin inhibitors and mineralocorticoid receptor antagonists. Among patients not familiar with these therapies, significant proportions questioned their effectiveness and/or safety. Enhanced patient education and shared decision-making support may be effective strategies to improve the uptake of GDMT for HF in US clinical practice.
Samsky et al. (Sun,) conducted a cross-sectional in Heart failure (n=429). Guideline-directed medical therapy (GDMT) for heart failure was evaluated on Familiarity and concerns with HF medications. In a survey of 429 US adults with heart failure, only 24.9% reported familiarity with angiotensin receptor-neprilysin inhibitors or mineralocorticoid receptor antagonists.
