- Objectives To determine the incidence rate (IR) of myocardial infarction (MI), relative risk of MI, and impact of incident MI on mortality in individuals with biopsy-confirmed giant cell arteritis (GCA). Methods MIs in individuals diagnosed with GCA 1998-2016 in Skåne, Sweden were identified by searching the SWEDEHEART register, a record of all patients receiving care for MI in a coronary care unit (CCU). The regional diagnosis database, with subsequent case review, identified GCA patients receiving care for MI outside of a CCU. A cohort of 10 reference subjects for each GCA case, matched for age, sex and area of residence, was used to calculate the incidence rate ratio (IRR) of MI in GCA to that in the general population. Results The GCA cohort comprised 1134 individuals. During 7958 person-years of follow-up, 102 were diagnosed with incident MI, yielding an IR of 12.8 per 1000 person-years (95% CI 10.3 to 15.3). The IR was highest in the 30 days following GCA diagnosis and declined thereafter. The IRR of MI in GCA to that of the background population was 1.29 (95% CI 1.05 to 1.59). Mortality was higher in GCA patients who experienced incident MI than in those without MI (HR 2.8; 95% CI 2.2 to 3.6). Conclusions The highest incidence of MI occurs within the 30 days following diagnosis of GCA. Individuals with GCA have a moderately increased risk of MI compared with a reference population. Incident MI has a major impact on mortality in GCA.

- Background. Ruling out acute myocardial infarction (AMI) in the emergency department (ED) is challenging. Studies have shown that a high-sensitivity cardiac troponin T (hs-cTnT) <5 ng/L or <6 ng/L at presentation (0 h) can be used to rule out AMI. The objective of this study was to identify whether an even higher hs-cTnT threshold can be used for a safe rule out of AMI in the ED. Methods. The derivation cohort consisted of 24,973 ED patients with a primary complaint of chest pain. In this cohort, we identified the highest concentration of 0 h hs-cTnT that corresponded to a negative predictive value (NPV) of ≥99.5% for the primary endpoint of AMI/all-cause death within 30 days and the secondary endpoint of all-cause death within one year. The results were validated in two cohorts consisting of 132,021 and 1167 ED chest pain patients. Results. The 0 h hs-cTnT threshold corresponding to a NPV of ≥99.5% for the primary endpoint was <9 ng/L (NPV: 99.6% and 95% CI: 99.5-99.7). This cutoff provided a sensitivity of 96.2% (95% CI: 95.2-97.1) and identified 59.7% of the patients as low risk compared to 35.8% and 43.9% with a 0 h hs-cTnT <5 ng/L and <6 ng/L, respectively. The results were similar in the validation cohorts and seemed to perform even better in patients where the 0 h hs-cTnT was measured >3 h after symptom onset and in those with a nonischemic ECG and nonhigh risk history. Conclusions. A 0 h hs-cTnT cutoff of <9 ng/L safely rules out AMI/death within 30 days in a majority of chest pain patients and is a more effective strategy than the currently recommended <5 ng/L and <6 ng/L cutoffs. This trial is registered with NCT03421873.

- Dual antiplatelet therapy (DAPT) reduces ischemic events but increases bleeding risk, especially in patients with high bleeding risk (HBR). This study aimed to compare outcomes of abbreviated versus standard DAPT strategies in patients with HBR with acute coronary syndrome undergoing percutaneous coronary intervention.Patients from the SWEDEHEART (Swedish Web-system for Enhancement and Development of Evidence-Based Bare in Heart Disease Evaluated According to Recommended Therapies) registry with at least 1 HBR criterion who underwent percutaneous coronary intervention for acute coronary syndrome were identified and included. Patients were divided into 2 groups based on their planned DAPT time at discharge: 12-month DAPT or an abbreviated DAPT strategy and matched according to their prescribed P2Y12 inhibitor at discharge. The primary outcome assessed was time to net adverse clinical events at 1year, which encompassed cardiac death, myocardial infarction, ischemic stroke, or clinically significant bleeding. Time to major adverse cardiovascular events and the individual components of net adverse clinical events were considered secondary end points. A total of 4583 patients were included in each group. The most frequently met HBR criteria was age older than 75years (65.6%) and Predicting Bleeding Complications in Patients Undergoing Stent Implantation and Subsequent Dual Antiplatelet Therapy score ≥25 (44.6%) in the standard DAPT group and oral anticoagulant therapy (79.6%) and age 75years and older (55.2%) in the abbreviated DAPT group. There was no statistically significant difference in net adverse clinical events (12.9% versus 13.1%; hazard ratio [HR], 0.99 [95% CI, 0.88-1.11], P=0.83), major adverse cardiovascular events (8.6% versus 7.9%; HR, 1.08 [95% CI, 0.94-1.25]), or their components between groups. The results were consistent among all of the investigated subgroups.In patients with HBR undergoing percutaneous coronary intervention due to acute coronary syndrome, abbreviated DAPT was associated with comparable rates of net adverse clinical events and major adverse cardiovascular events to a DAPT duration of 12months.

- BackgroundSodium-glucose co-transporter 2 (SGLT2) inhibitors have been shown to reduce rates of heart failure hospitalisations and cardiovascular death in patients with type 2 diabetes and prior cardiovascular disease. We hypothesised that SGLT2 inhibitors could provide cardiovascular benefits in the post-myocardial infarction setting. We aimed to investigate cardiovascular outcomes of SGLT2 inhibitor therapy in patients with type 2 diabetes mellitus after myocardial infarction in a Swedish nationwide registry.MethodsWe included all patients with type 2 diabetes surviving a type 1 acute myocardial infarction from January 1, 2018 to December 31, 2021. Patients were included if they were discharged with an estimated glomerular filtration rate (eGFR) > 30 mL/min/1.73 m2 in the nationwide Swedish Web-system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapies (SWEDEHEART) registry. We identified all patients discharged with or without an SGLT2 inhibitor prescription 120 days before or within three days after discharge from the cardiac care unit. The primary outcome measure was a composite of death and first hospitalisation for heart failure after one year analysed using an adjusted Cox regression.FindingsA total of 11,271 patients were included. Of these, 2498 (22.2%) received SGLT2 inhibitor treatment. Patients who were prescribed SGLT2 inhibitors were younger, more often presented with a STEMI and had worse left ventricular ejection fraction at index hospitalisation. SGLT2 inhibitor use was associated with lower rates of the composite outcome (hazard ratio (HR) of 0.70 (95% confidence interval (CI) 0.59–0.82).InterpretationTreatment with SGLT2 inhibitors after myocardial infarction in patients with type 2 diabetes was associated with a lower rate of cardiovascular events.

- BACKGROUND: Percutaneous coronary intervention (PCI) is frequently used for patients with chronic coronary syndrome (CCS). However, the role of PCI beyond symptom relief in CCS remains controversial. The objective of this study was to determine whether PCI is associated with better outcomes, compared with medical therapy (MT) alone.METHODS: We conducted a retrospective cohort study. Using the Swedish Coronary Angiography and Angioplasty Registry, we included all patients with CCS undergoing coronary angiography in Sweden between 2010 and 2020. Two groups were formed based on treatment strategy: PCI+MT versus MT alone. One-to-one propensity score (PS) matching was used to address confounding. Outcome was assessed using matched win ratio analysis, a statistical method that ranks the components of the composite by clinical importance. The primary outcome was net adverse clinical event (NACE) within 5 years. In the win ratio analysis, the components of NACE were ranked as follows: (1) all-cause mortality, (2) myocardial infarction (MI), (3) bleeding and (4) urgent revascularisation. Secondary outcomes were the individual components of NACE, major adverse cardiovascular events (MACE) and cardiovascular mortality.RESULTS: After PS matching, two groups of 7220 patients each were formed. The hierarchical outcome analysis of NACE and MACE showed that PCI was associated with improved outcome (matched win ratio: 1.28 (95% CI 1.20 to 1.36, p<0.001) and matched win ratio: 1.38 (95% CI 1.29 to 1.48, p<0.001), respectively). The use of PCI was associated with higher win ratio of MI (matched win ratio: 1.15, 95% CI 1.04 to 1.28, p=0.008), urgent revascularisation (matched win ratio: 1.85, 95% CI 1.69 to 2.03, p<0.001) and cardiovascular mortality (matched win ratio: 1.15, 95% CI 1.00 to 1.34, p=0.044). No difference in win ratio was observed for all-cause mortality or bleeding.CONCLUSIONS: In this study, which sought to evaluate the outcomes of patients with CCS using a hierarchical approach, patients selected for revascularisation with PCI experienced better outcome compared with MT alone.
