We aimed to assess the prevalence of GDMT use for HF across geographic regions and country-income levels. We systematically reviewed observational studies (published between January 2010 and October 2020) involving patients with HF with reduced ejection fraction. We conducted random-effects meta-analyses to obtain summary estimates. We included 334 studies comprising 1,507,849 patients (31% female). The majority (82%) of studies were from high-income countries, with Europe (45%) and the Americas (33%) being the most represented regions, and Africa (1%) being the least. Overall prevalence of GDMT use was 80% (95% CI 78%\u201381%) for \u03b2-blockers, 82% (80%\u201383%) for renin\u2013angiotensin-system inhibitors, and 41% (39%\u201343%) for mineralocorticoid receptor antagonists. We observed an exponential increase in GDMT use over time after adjusting for country-income levels (p &lt; 0.0001), but significant gaps persist in low- and middle-income countries. Multi-level interventions are needed to address health-system, provider, and patient-level barriers to GDMT use.<\/jats:p>","DOI":"10.5334\/gh.1355","type":"journal-article","created":{"date-parts":[[2024,9,12]],"date-time":"2024-09-12T11:31:59Z","timestamp":1726140719000},"page":"74","source":"Crossref","is-referenced-by-count":17,"title":["Use of Guideline-Recommended Heart Failure Drugs in High-, Middle-, and Low-Income Countries: A Systematic Review and Meta-Analysis"],"prefix":"10.5334","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2211-145X","authenticated-orcid":false,"given":"Gautam","family":"Satheesh","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rupasvi","family":"Dhurjati","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laura","family":"Alston","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fisaha","family":"Tesfay","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rashmi","family":"Pant","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ehete","family":"Bahiru","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudia","family":"Bambs","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anubha","family":"Agarwal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sanne A.
