Global differences in acute heart failure treatment: analysis of the STRONG-HF site feasibility questionnaire.

aimsAcute heart failure (AHF) has an impact on human health worldwide. Despite guidelines for treatment and management of AHF, mortality rates remain high. The main objective of this study was to compare standard in-hospital treatment and management of AHF against current clinical guidelines and variations across regions.

methodsBetween February 2018 and May 2021, investigators were approached to participate in the STRONG-HF study. The lead investigator at 158 sites in 20 countries completed a site feasibility questionnaire. Sites were grouped by country into five different regions: Africa and the Middle East, Eastern Europe, Russia, South America, and Western Europe.

resultsAccording to the questionnaires, there are large differences in how patients present due to AHF and where in the hospital they are treated. There were significant differences in reported percentage of AHF patients receiving angiotensin converting enzymes inhibitors across the regions (P < 0.001), mostly due to prescription of more angiotensin II receptor blockers and angiotensin receptor-neprilysin inhibitors in South America and Western Europe. Reported beta-blocker use was high across all of the regions. Device therapy and percutaneous interventions were more common in Europe. Sites reported a 5 to 8 day length of stay, while in Russia most have a 10 to 12 day length of stay. Regions reported that AHF patients follow up with a community cardiologist or general practitioner post-discharge, although follow-up was commonly more than 1 month post discharge, and not all sites had the capability to measure natriuretic peptides post discharge.

conclusionsIn this analysis of feasibility questionnaires, most sites reported general adherence to ESC guidelines for treatment and management of AHF patients although percutaneous and device therapy was less common outside Europe and follow-up after discharge took place late and was not as extensive as recommended. There were wide variations seen within and across regions in some areas.
