IntroductionHeart failure (HF) is a clinical syndrome with symptoms and/or signs caused by a structural and/or functional cardiac abnormality and corroborated by elevated natriuretic peptide levels and/or objective evidence of pulmonary or systemic congestion. Among HF types, HF with preserved ejection fraction (HFpEF) is the commonest form. However, the diagnosis and management of HFpEF are challenging. In addition, the perception of healthcare professionals (HCPs) towards the diagnosis and management of HFpEF patients differs due to the existing gap between the guidelines and daily clinical practice. Therefore, an online survey was conducted to understand the HCPs’ knowledge and practice gaps in the diagnosis, treatment, and management of patients with HFpEF.MethodsA total of 160 respondents, i.e., cardiologists, internists, and cardiology residents from different community-based practices and hospitals across Indonesia participated in an online continuing medical education (CME) survey. A questionnaire was formulated to assess awareness, current practice patterns, challenges, and confidence of the HCPs related to the HFpEF.ResultsHCPs stated that diagnosis of HF is the prime responsibility of cardiologists and general physicians but not of general internists. According to the HCPs, reduction in mortality, reduction in hospitalization, and improved quality of life are the most important goals of HF treatment. The perceived prevalence of HFpEF is estimated to be 30-60% and mortality rates of HFpEF and HF with reduced ejection fraction (HFrEF) are similar. Further, mixed types of responses with different combinations of diagnosis, treatment, and prevention, were obtained when HCPs were asked about the challenges faced in HFpEF. Among the therapies, angiotensin-converting enzyme (ACE) inhibitors, mineralocorticoid receptor antagonists (MRA), beta-blockers, and diuretics are frequently used for the treatment of HF.ConclusionThe perception of the HCPs toward the diagnosis and management of HFpEF may affect optimal care. Based on our findings, the cardiologists are well aware of the current situation of HF in Indonesia and treat patients with HFpEF effectively.
