Background: Low cardiorespiratory fitness is an established risk predictor for chronic non-communicable diseases. We aimed to investigate the prognostic significance of fitness level on the risk of major adverse cardiac events (MACE, the composite of myocardial infarction, stroke, or all-cause death), in a contemporary cohort of middle-aged subjects without cardiovascular disease. Methods: Retrospective analysis of patients aged 40–60 years without a history of cardiovascular disease. Degree of fitness was determined according to a graded, maximal treadmill exercise stress testing (EST) time achieved, classified into age- and sex-specific quintiles (Q), and categorized as low (Q1), moderate (Q2–Q4) or high (Q5) fitness groups. A multivariable Cox proportional hazard regression model was used to assess the association of fitness level with the risk of MACE. Results: A total of 6836 patients were included, of which 44.5% were women, and the mean age was 52 years. Overall, 289 MACE events occurred during a median follow-up of 7 years. Level of fitness was inversely associated with the presence of cardiovascular risk factors. The multivariable adjusted hazard ratio (95% confidence interval) for MACE was 1.65 (1.12–2.44) and 2.17 (1.40–3.38) in those at moderate and low fitness levels, compared to the high-fitness group (reference), respectively. For each decrease of one metabolic equivalent (MET) unit achieved at peak exercise, the relative risk for MACE increased by 18%. The association between low fitness and MACE was not modified by other risk factors (P-for-interaction non-significant). Conclusions: Low fitness level, as captured by a maximal treadmill EST, is an independent risk predictor for MACE among middle-age individuals without known cardiovascular disease. The association of low fitness with high burden of cardiometabolic risk factors highlight the importance of lifestyle intervention in this patient population.

• MR is a dynamic condition affected by multiple hemodynamic factors. • MV assessment should be performed under optimal psychological factors. • Routine preassessment of BP should be considered when evaluating for MV disease.

Background: Real-world data on the implementation and prognostic impact of glucose-lowering drugs with proven cardiovascular benefits in patients with type 2 diabetes (T2D) following acute coronary syndrome (ACS) are limited. We investigated the utilization and treatment patterns of sodium–glucose contrasporter-2 inhibitors (SGLT2Is) and glucagon-like peptide-1 recepto-agonists (GLP1RAs) in patients with T2D experiencing ACS and analyzed their association with mortality and major adverse cardiovascular events (MACEs) including recurrent ACS, acute revascularization, heart failure, or ischemic stroke. Methods: We carried out a retrospective analysis of 9756 patients with T2D from a nationwide healthcare organization in Israel who were hospitalized with ACS between 01/2019 and 01/2022. Drug prescriptions were estimated pre-hospitalization, 90 days, and 1 year following hospitalization. The association between SGLT2I and/or GLP1RA treatment with MACE and mortality was investigated using a time-dependent Cox regression analysis with multivariable adjustment. Results: The prescription rates (pre-hospitalization, 90 days, and 1 year post-hospitalization) of GLP1RAs were 13%, 13.2%, and 18%, and those of SGLT2Is were 23.9%, 33.6%, and 42.7%, respectively. At 1 year, 13.9% of patients were prescribed both treatments. The use of SGLT2Is and/or GLP1RAs was higher in younger age groups and increased from 2019 to 2021 (38.1% to 59.2%). The adjusted hazard ratio for the association of pre- or post-hospitalization SGLT2I and/or GLP1RA treatment with mortality and MACE was 0.724 (0.654–0.801) and 0.974 (0.909–1.043), respectively. Conclusions: In the real-world practice of treating patients with T2D experiencing ACS, the implementation of SGLT2Is, particularly GLP1RAs, was suboptimal when prescribed both early and 1 year following hospitalization, emphasizing the need to improve medical care. Treatment with SGLT2Is and/or GLP1RAs was associated with a favorable impact on mortality but not MACE.

A variety of noncardiac conditions mimic the electrocardiographic changes of ST-elevation myocardial infarction (STEMI). Therefore, a physician must maintain a high index of suspicion when evaluating ST-segment elevation (STE). We present a case of epigastric pain secondary to ileus and gastric dilatation masquerading as anterolateral STEMI on an electrocardiogram (ECG). The STE promptly resolved following laparotomy. To the best of our knowledge, this is the first case of anterolateral STE secondary to gastric dilatation.
