Background and Purpose— Diabetes mellitus (DM) and non-DM patients without coronary artery disease (CAD) have a similar low risk of myocardial infarction after coronary angiography. The risk of ischemic stroke in DM patients dependent on CAD status is less explored. We examined whether DM patients without CAD have a risk of ischemic stroke similar to that in patients with neither DM nor CAD. Methods— We conducted a cohort study of patients who underwent coronary angiography between 2004 and 2012 in Western Denmark. Patients diagnosed with previous ischemic stroke or transient ischemic attack were excluded. Patients were stratified according to the presence of DM and CAD. Follow-up started 30 days after coronary angiography. We computed event rates and adjusted incidence rate ratios using patients without DM or CAD as reference. We examined the trend between CAD extent and ischemic stroke in patients with DM. Results— A total of 81 909 patients were included. Median follow-up was 3.8 years. Patients with both DM and CAD were at the highest risk of ischemic stroke (1.32 events per 100 person-years; adjusted incidence rate ratio, 2.00 [95% CI, 1.72–2.32]). Patients with CAD alone (0.77 events per 100 person-years; adjusted incidence rate ratio, 1.27 [95% CI, 1.12–1.44]) or DM alone (0.95 events per 100 person-years; adjusted incidence rate ratio, 1.74 [95% CI, 1.42–2.15]) were at intermediate risk, whereas patients with neither DM nor CAD (0.52 events per 100 person-years) were at the lowest risk. Among patients with DM, extent of CAD was further predictive of risk ( P trend <0.001). Conclusions— Not only CAD but also DM are associated with the risk of ischemic stroke after coronary angiography. Their combination further increases the risk of ischemic stroke depending on the extent of CAD.

Aims The DANish Acute Myocardial Infarction 2 (DANAMI-2) trial found that interhospital transport to primary percutaneous coronary intervention (pPCI) was superior to fibrinolysis at the local hospital in patients with ST-segment elevation myocardial infarction (STEMI) at 30 days. The present study investigates the 16-year cardiovascular outcomes. Methods and results We randomized 1572 STEMI patients to pPCI or fibrinolysis at 24 referral hospitals and 5 invasive centres in Denmark. Patients randomized to pPCI at referral hospitals were immediately transported to the nearest invasive centre. The main endpoint of the current study was a composite of death or rehospitalization for myocardial infarction (MI). Outcome information beyond 3 years was obtained through Danish health registries. After 16 years, pPCI-treated patients had a sustained lower rate of composite endpoint compared to patients treated with fibrinolysis in the overall cohort [58.7% vs. 62.3%; hazard ratio (HR) 0.86, 95% confidence interval (CI) 0.76–0.98], and among patients transported for pPCI (58.7% vs. 64.1%; HR 0.82, 95% CI 0.71–0.96). No difference in all-cause mortality was found, but cardiac mortality was reduced by an absolute of 4.4% in favour of pPCI (18.3% vs. 22.7%; HR 0.78, 95% CI 0.63–0.98). pPCI postponed a main event with 12.3 months in average compared to fibrinolysis (95% CI 5.0–19.5). Conclusion The benefit of pPCI over fibrinolysis was maintained at 16-year follow-up. pPCI reduced the composite endpoint of death or rehospitalization for MI, reduced cardiac mortality, and delayed average time to a main event by approximately 1 year.

IntroductionRheumatoid arthritis (RA) is a risk factor for cardiovascular disease. The clinical consequences of coincident RA and coronary artery disease (CAD) are unknown.ObjectiveWe aimed to estimate the impact of RA on the risk of adverse cardiovascular events in patients with and without CAD.MethodsA population-based cohort of patients registered in the Western Denmark Heart Registry, who underwent coronary angiography (CAG) between 2003 and 2016, was stratified according to the presence of RA and CAD. Endpoints were myocardial infarction (MI), major adverse cardiovascular events (MACE; MI, ischaemic stroke and cardiac death) and all-cause mortality.ResultsA total of 125 331 patients were included (RA: n=1732). Median follow-up was 5.2 years. Using patients with neither RA nor CAD as reference (cumulative MI incidence 2.7%), the 10-year risk of MI was increased for patients with RA alone (3.8%; adjusted incidence rate ratio (IRRadj) 1.63, 95% CI 1.04 to 2.54), for patients with CAD alone (9.9%; IRRadj 3.35, 95% CI 3.10 to 3.62), and highest for patients with both RA and CAD (12.2%; IRRadj 4.53, 95% CI 3.66 to 5.59). Similar associations were observed for MACE an all-cause mortality.ConclusionsIn patients undergoing CAG, RA is significantly associated with the 10-year risk of MI, MACE and all-cause mortality regardless of the presence of CAD. However, patients with RA and CAD carry the largest risk, while the additive risk of RA in patients without CAD is minor. Among patients with RA, risk stratification by presence or absence of documented CAD may allow for screening and personalised treatment strategies

OBJECTIVE We examined temporal trends in risk of first-time ischemic stroke in patients with incident type 2 diabetes mellitus (T2DM) and no prior atherosclerotic cardiovascular disease (ASCVD). RESEARCH DESIGN AND METHODS Using nationwide health registries, we identified all patients with incident T2DM without a prior hospital diagnosis of ASCVD from 1996 to 2015 in Denmark. Patients were assigned to 5-year periods based on the date of T2DM diagnosis and were followed for 5 years. Each patient was matched by sex and age with up to three individuals from the general population. Temporal trends in ischemic stroke were examined using Cox regression to compute hazard ratios (HRs). Temporal use of prophylactic cardiovascular medications was also assessed. RESULTS The study comprised 288,825 patients with incident T2DM and 782,232 general population individuals. From 1996–2000 to 2011–2015, the 5-year risk of first-time ischemic stroke was approximately halved in the T2DM cohort (5.2% vs. 2.7%; sex- and age-adjusted HR 0.52 [95% CI 0.49–0.55]). Patients diagnosed in 2011–2015 had increased risk of ischemic stroke compared with individuals in the general population; however, the risk difference narrowed over time (5.2% vs. 2.9% in 1996–1999 [difference 2.3%]; 2.7% vs. 2.0% in 2011–2015 [difference 0.7%]). Use of prophylactic cardiovascular medications increased markedly during the overall study period, especially use of statins (5% to 50%) and multiple antihypertensive drugs (18% to 33%). CONCLUSIONS From 1996 to 2015, the 5-year risk of first-time ischemic stroke was approximately halved in patients with incident T2DM and no prior ASCVD, coinciding with markedly increased use of prophylactic cardiovascular medications.

Background: Diabetes is considered a risk factor for myocardial infarction. However, we have previously found that diabetes was not a short-term risk factor for myocardial infarction in the absence of obstructive coronary artery disease. Methods: We conducted a cohort study of patients undergoing coronary angiography from 2003 to 2012 and followed them by cross-linking Danish health registries. Patients were stratified according to coronary artery disease and diabetes. Endpoints included myocardial infarction, cardiac death, all-cause death and coronary revascularization. Results: 86,202 patients were included in total (diabetes: n = 12,652). Median follow-up was 8.8 years. Using patients with neither coronary artery disease nor diabetes as reference (cumulative myocardial infarction incidence 2.6%), the risk of myocardial infarction was low and not substantially increased for patients with diabetes alone (3.2%; hazard ratio 1.202, 95% confidence interval 0.996−1.451), was increased for patients with coronary artery disease alone (9.3%; hazard ratio 2.75, 95% confidence interval 2.52−3.01) and was highest for patients with both coronary artery disease and diabetes (12.3%; hazard ratio 3.79, 95% confidence interval 3.43−4.20). Similar associations were observed for cardiac death and coronary revascularization. Conclusion: Diabetes patients without coronary artery disease by coronary angiography have a low risk of myocardial infarction, not substantially increased compared to patients with neither coronary artery disease nor diabetes. In the presence of coronary artery disease, however, diabetes increases the risk of myocardial infarction.
