Cardiac amyloidosis (CA) is still an underdiagnosed cause of heart failure (HF) and early disease recognition and timely disease-modifying therapy (DMT) administration translate to better outcomes. We aimed to assess CA screening and management approaches for patients with HF preserved ejection fraction (HFpEF) among physicians worldwide. An independent academic web-based survey was distributed worldwide between May 2023 and July 2023. Overall, 1,460 physicians (61% were men, median age was 42 [34 to 49] years) from 95 countries completed the survey. A total of 2/3 of respondents had experience diagnosing CA and reported having 10% of patients with CA in patients with HFpEF. Systematic screening for CA of all patients with HFpEF was performed by 10% of responders, whereas 24% did not consider the screening. Most responders (39%) used left ventricular hypertrophy as a screening criterion. Serum protein electrophoresis with immunofixation of free light chain and urine protein electrophoresis or cardiac magnetic resonance were selected by half of the responders as a first-line diagnostic tool. The combination of serum protein electrophoresis with immunofixation free light chain, urine protein electrophoresis, and bone scintigraphy was considered by 32% of the participants. CA DMT was available for 48% of the physicians. About 82% of responders would administrate HF to patients with HFpEF with CA, with the most preferable drugs being diuretics, sodium-glucose cotransporter-2 inhibitors, and renin-angiotensin-aldosterone system inhibitors. In conclusion, the results reveal the uncertainties among physicians worldwide regarding the need for CA screening of patients with HFpEF. CA remains a disease with very heterogeneous management, particularly, in the screening and diagnostic workup. The HF community should aim to educate on CA and improve access to DMT. © 2024 Elsevier Inc.

Background and aims: There is a gap in knowledge about implementing diagnostic tools and therapy for heart failure with preserved ejection fraction (HFpEF) in clinical practice. This survey aimed to assess real-world practice in HFpEF diagnosis and treatment in the international medical community. Methods: An independent academic web-based 29-question survey was designed by a group of heart failure specialists and posted by email and through scientific societies and social networks to a broad community of physicians worldwide. Results: 1.460 physicians from 95 countries answered the survey, with a mean age of 42.2±10.4 years, 39.4 % females, and 85.1 % were cardiologists. The left ventricular ejection fraction cut-off value selected for HFpEF diagnosis was 50 % for 89 % of participants. The scores for the probability of diagnosis of HFpEF were used only by 47.2 %, and H2FPEF was the most used score (31 %). Natriuretic peptides were used by 87.4 % of participants for the diagnostic workup, while the diastolic stress test was only used by 26.2 %. 54.4 % of participants chose SGLT2 inhibitors as their first drug treatment, followed by diuretics (18.6 %) and ACE inhibitors (8.4 %). Conclusions: In an international academic survey on HFpEF management, the criteria for screening and diagnosis of HFpEF patients remain aligned with classic international guidelines with a low use of diagnostic scores. SGLT2i is the leading therapeutic drug class used for this heterogeneous patient population. These results raise the need to improve education and awareness on diagnosing and managing HFpEF patients. © 2024 Elsevier Inc.
