Abstract Background Cardiovascular disease (CVD) is the leading cause of premature death among women, and the negative impact on public health is profound. Women have higher rates of comorbidities, complications such as stroke, in addition to higher mortality compared to men (1-6) and targeting sex-related differences regarding the treatment of CVD in women is of great importance to prevent the number of CVD events. The purpose of this study was to get an overview of the systematic reviews and meta-analyses investigating sex differences in patients with acute myocardial infarction (AMI) the past 10 years. Methods A systematic search was carried out in Epistemonikos, the largest database of systematic reviews that screens PubMed, Cochrane, Embase, CINAHL, PsycInfo and others (i.e., currently nine databases) (7, 8). The search was conducted 12 January 2024, with the general search strings: (1) sex differences OR gender differences AND myocardial infarction, (2) sex differences OR gender differences OR women OR female AND myocardial infarction. The search was restricted to systematic reviews conducted the last 10 years. Results Forty-nine (search 1: 19, search 2: 30) systematic reviews and meta-analyses were identified, and five studies investigating sex differences in relation to AMI were included. Two systematic reviews, Babioakis (2021) and Meer (2015), reported of longer door-to-balloon (D2B) time and/or symptom-to-balloon (S2B) time in female patients presenting with STEMI and referred for PCI, compared to male patients (9). Chaudhary (2022) investigated adverse event of MINOCA (more commonly in women/ younger age (51-59 years) and reported higher risk of MACE among women than men (10.1% vs. 9.1%, OR 1.15, 1.04-1.23), in addition to higher incidence of stroke (3.5% vs. 2.2%, OR 1.3, 1.01-1.68), however no significantly differences were observed for all-cause mortality, non-fatal AMI, and cardiovascular readmissions between the groups (10). Three systematic reviews reported of higher risk of mortality after STEMI among women, compared to men (11-13). Xi (2022) reported of higher risk of short-term mortality (RR, 1.73; 95% CI 1.53 to 1.96)) (adjusted RR, 1.24; 95% CI 1.11 to 1.38) (13), Pancholy (2014) reported of higher risk of in-hospital mortality (RR, 1.93; 95% CI, 1.75-2.14) (adjusted RR, 1.48; 95% CI, 1.07-2.05) (11), and van der Meer (2015) reported of higher crude short- and long-term mortality in women, in addition to less use of GP IIb/IIIa inhibitors in women, compared to men (women 51%, men 57%) (12). Conclusions Our umbrella review revealed that women had longer timeline for treatment in AMI, had less use of medication and higher risk of mortality and MACE compared to men. Clinical practice needs further improvements in management in female patients.
