Use of SGLT2 inhibitors and GLP-1 receptor agonists in patients with ischaemic heart disease and type 2 diabetes in Swedish primary care: a cross-sectional analysis of regional primary care registry data (QregPV)

OBJECTIVES: To assess the use of sodium-glucose cotransporter 2 inhibitors (SGLT2i) and glucagon-like peptide 1 receptor agonists (GLP-1 RA) among patients with coexisting ischaemic heart disease (IHD) and type 2 diabetes (T2D) in primary care, in relation to European guidelines. DESIGN: Cross-sectional observational study. SETTING: 209 primary healthcare centres in Region Västra Götaland, Sweden (population 1.8 million in 2023). PARTICIPANTS: 14 414 patients with registered prevalent diagnoses of coexisting IHD and T2D, September 2023, in QregPV, the regional primary care quality of care register in Region Västra Götaland. Data on dispensed drugs were retrieved from the regional prescribed drug register, Digitalis. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was the proportion of patients with dispensed SGLT2i or GLP-1 RA in relation to sex, age and primary healthcare centres (including private vs public ownership). The secondary outcome was estimated additional prescription costs. RESULTS: SGLT2i was dispensed to 37.2%, less often to women (adjusted OR (aOR) 0.64 (95% CI 0.59 to 0.70)). GLP-1 RA was dispensed to 10.0%, with no sex difference (aOR 1.04 (95% CI 0.92 to 1.18)). Use of SGLT2i and GLP-1 RA declined with age (p
