RESUMEN
BACKGROUND: Patients with diabetes have increased rates of major adverse cardiac events (MACEs). We hypothesized that this is explained by diabetes-associated differences in coronary plaque morphology and lipid content. METHODS: In PROSPECT II (Providing Regional Observations to Study Predictors of Events in the Coronary Tree), 898 patients with acute myocardial infarction with or without ST-segment elevation underwent 3-vessel quantitative coronary angiography and coregistered near-infrared spectroscopy and intravascular ultrasound imaging after successful percutaneous coronary intervention. Subsequent MACEs were adjudicated to either treated culprit lesions or untreated nonculprit lesions. This substudy stratified patients by diabetes status and assessed baseline culprit and nonculprit prevalence of high-risk plaque characteristics defined as maximum plaque burden ≥70% and maximum lipid core burden index ≥324.7. Separate covariate-adjusted multivariable models were performed to identify whether diabetes was associated with nonculprit lesion-related MACEs and high-risk plaque characteristics. RESULTS: Diabetes was present in 109 of 898 patients (12.1%). During a median 3.7-year follow-up, MACEs occurred more frequently in patients with versus without diabetes (20.1% versus 13.5% [odds ratio (OR), 1.94 (95% CI, 1.14-3.30)]), primarily attributable to increased risk of myocardial infarction related to culprit lesion restenosis (4.3% versus 1.1% [OR, 3.78 (95% CI, 1.12-12.77)]) and nonculprit lesion-related spontaneous myocardial infarction (9.3% versus 3.8% [OR, 2.74 (95% CI, 1.25-6.04)]). However, baseline prevalence of high-risk plaque characteristics was similar for patients with versus without diabetes concerning culprit (maximum plaque burden ≥70%: 90% versus 93%, P=0.34; maximum lipid core burden index ≥324.7: 66% versus 70%, P=0.49) and nonculprit lesions (maximum plaque burden ≥70%: 23% versus 22%, P=0.37; maximum lipid core burden index ≥324.7: 26% versus 24%, P=0.47). In multivariable models, diabetes was associated with MACEs in nonculprit lesions (adjusted OR, 2.47 [95% CI, 1.21-5.04]) but not with prevalence of high-risk plaque characteristics (adjusted OR, 1.21 [95% CI, 0.86-1.69]). CONCLUSIONS: Among patients with recent myocardial infarction, both treated and untreated lesions contributed to the diabetes-associated ≈2-fold increased MACE rate during the 3.7-year follow-up. Diabetes-related plaque characteristics that might underlie this increased risk were not identified by multimodality imaging. REGISTRATION: URL: https://www.

BACKGROUND: Peripheral artery disease is the leading cause of nontraumatic lower limb amputation. Microvascular disease (MVD) increases the risk of lower limb amputation in patients with peripheral artery disease (PAD). We estimated the risk of lower limb amputation associated with MVD and PAD in a Danish cohort. METHODS: We included every resident without previous lower limb amputation in Western Denmark aged 50-75 years on 1 January 2012 and followed them for 7 years. Participants were stratified by MVD and PAD. We estimated adjusted hazard ratios of lower limb amputation using individuals with no MVD and no PAD as reference. We also provide a sex-specific analysis and estimated the population attributable fraction of the male sex. RESULTS: We included 933,597 individuals, of whom 16,741 had MVD only, 18,217 had PAD only and 1,827 had MVD and PAD. Both MVD only (adjusted hazard ratio 3.36, 95% CI 2.98-3.73) and PAD only (adjusted hazard ratio 7.32, 95% CI 6.62-8.08) increased the risk of lower limb amputation separately. Individuals with MVD and PAD had the highest risk of amputation (adjusted hazard ratio 12.27, 95% CI 10.43-14.80). Men had an increased absolute risk of amputation. The population attributable fraction associated with the male sex was 31%. CONCLUSIONS: Microvascular disease and PAD are independently associated with a threefold and sevenfold increase of amputation risk, respectively. Combined, they had an additive effect constituting a 12-fold amputation risk. The amputation risk was higher in men than women, and 3 in 10 amputations were attributed to the male sex.

BACKGROUND: Diabetes patients without obstructive coronary artery disease as assessed by coronary angiography have a low risk of myocardial infarction, but their myocardial infarction risk may still be higher than the general population. We examined the 10-year risks of myocardial infarction, ischemic stroke, and death in diabetes patients without obstructive coronary artery disease according to coronary angiography, compared to risks in a matched general population cohort. METHODS: We included all diabetes patients without obstructive coronary artery disease examined by coronary angiography from 2003 to 2016 in Western Denmark. Patients were matched by age and sex with a cohort from the Western Denmark general population without a previous myocardial infarction or coronary revascularization. Outcomes were myocardial infarction, ischemic stroke, and death. Ten-year cumulative incidences were computed. Adjusted hazard ratios (HR) then were computed using stratified Cox regression with the general population as reference. RESULTS: We identified 5734 diabetes patients without obstructive coronary artery disease and 28,670 matched individuals from the general population. Median follow-up was 7 years. Diabetes patients without obstructive coronary artery disease had an almost similar 10-year risk of myocardial infarction (3.2% vs 2.9%, adjusted HR 0.93, 95% CI 0.72-1.20) compared to the general population, but had an increased risk of ischemic stroke (5.2% vs 2.2%, adjusted HR 1.87, 95% CI 1.47-2.38) and death (29.6% vs 17.8%, adjusted HR 1.24, 95% CI 1.13-1.36). CONCLUSIONS: Patients with diabetes and no obstructive coronary artery disease have a 10-year risk of myocardial infarction that is similar to that found in the general population. However, they still remain at increased risk of ischemic stroke and death.

BACKGROUND: It was recently shown that new-onset diabetes patients without previous cardiovascular disease have experienced a markedly reduced risk of adverse cardiovascular events from 1996 to 2011. However, it remains unknown if similar improvements are present following the diagnosis of chronic coronary syndrome. The purpose of this study was to examine the change in cardiovascular risk among diabetes patients with chronic coronary syndrome from 2004 to 2016. METHODS: We included patients with documentation of coronary artery disease by coronary angiography between 2004 and 2016 in Western Denmark. Patients were stratified by year of index coronary angiography (2004-2006, 2007-2009, 2010-2012, and 2013-2016) and followed for two years. The main outcome was major adverse cardiovascular events (MACE) defined as myocardial infarction, ischemic stroke, or death. Analyses were performed separately in patients with and without diabetes. We estimated two-year risk of each outcome and adjusted incidence rate ratios (aIRR) using patients examined in 2004-2006 as reference. RESULTS: Among 5931 patients with diabetes, two-year MACE risks were 8.4% in 2004-2006, 8.5% in 2007-2009, and then decreased to 6.2% in 2010-2012 and 6.7% in 2013-2016 (2013-2016 vs 2004-2006: aIRR 0.70, 95% CI 0.53-0.93). In comparison, 23,540 patients without diabetes had event rates of 6.3%, 5.2%, 4.2%, and 3.9% for the study intervals (2013-2016 vs 2004-2006: aIRR 0.57, 95% CI 0.48-0.68). CONCLUSIONS: Between 2004 and 2016, the two-year relative risk of MACE decreased by 30% in patients with diabetes and chronic coronary syndrome, but slightly larger absolute and relative reductions were observed in patients without diabetes.

INTRODUCTION: Rheumatoid arthritis (RA) is a risk factor for cardiovascular disease. The clinical consequences of coincident RA and coronary artery disease (CAD) are unknown. OBJECTIVE: We aimed to estimate the impact of RA on the risk of adverse cardiovascular events in patients with and without CAD. METHODS: A 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. RESULTS: A 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. CONCLUSIONS: In 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.

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 (Ptrend<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.

AIM: Diabetes is associated with increased risk of dementia, but it is still debated to which degree this risk depends on the presence of atherosclerotic cardiovascular disease. We hypothesized that patients with diabetes and co-existing coronary artery disease (CAD), as a marker of systemic atherosclerotic cardiovascular disease, have substantially higher risk of developing dementia. METHODS: Patients ≥65 years, who underwent coronary angiography were stratified by diabetes and CAD. Outcomes were all-cause dementia, Alzheimer's dementia, and vascular dementia. We estimated adjusted hazard ratios (aHRs) using patients with neither diabetes nor CAD as a reference. RESULTS: A total of 103,859 patients were included. Of these, 23,189 (22%) had neither diabetes nor CAD, 3,876 (4%) had diabetes, 61,020 (59%) had CAD, and 15,774 (15%) had diabetes and CAD. During a median follow-up of 6.3 years, 5,592 (5.5%) patients were diagnosed with all-cause dementia. Patients with diabetes and CAD had the highest hazard rate of all-cause dementia (aHR 1.37, 95% CI 1.24-1.51), including Alzheimer's dementia (aHR 1.41, 95% CI 1.23-1.62) and vascular dementia (aHR 2.03, 95% CI 1.69-2.45). Patients with diabetes alone (aHR 1.14, 95% CI 0.97-1.33) or CAD alone (aHR 1.11, 95% CI 1.03-1.20) had a modestly increased rate of all-cause dementia. CONCLUSION: The combination of diabetes and CAD is associated with increased rate of dementia, in particular vascular dementia, suggesting that the diabetes-related risk of dementia is partly mediated through concomitant atherosclerotic cardiovascular disease. This underscores the importance of atherosclerotic cardiovascular disease prevention in diabetes patients to reduce cognitive decline.
We used national Danish healthcare registries to follow 103,859 patients examined by coronary angiography for up to 10 years to estimate the risk of dementia associated with diabetes and/or coronary artery disease. We found that diabetes and coronary artery disease are, separately, only modest risk factors of dementia. However, diabetes and coronary artery disease in combination were associated with highest risk of dementia, in particular vascular dementia. Out results suggests that the risk of dementia associated with diabetes is partly mediated through the presence atherosclerotic cardiovascular disease, which underscores the importance of atherosclerotic cardiovascular disease prevention in diabetes patients to reduce the risk of cognitive decline.
RESUMEN
BACKGROUND: In patients with newly diagnosed heart failure (HF) and left ventricular ejection fraction (LVEF) <50%, little is known whether LVEF per se or presence of coronary artery disease (CAD) provides independent prognostic information on all-cause mortality. METHODS AND RESULTS: Using the WDHR (Western Denmark Heart Registry), we identified 3620 patients with newly diagnosed HF and LVEF 10% to 49% referred for first-time coronary angiography as part of general workup of HF. Patients were stratified by LVEF (10%-35% versus 36%-49%) and presence of CAD. We estimated 10-year all-cause mortality risk and calculated hazard ratios adjusted for relevant comorbidities and risk factors (aHRs). CAD was present in 1592 (44%) patients. Lower LVEF was associated with a relative 15% increased 10-year mortality: 37% for LVEF 36% to 49% versus 42% for LVEF 10% to 35% (aHR, 1.15 [95% CI, 0.99-1.34]). This result did not change when stratified into those with CAD (52% versus 56%; aHR, 1.11 [95% CI, 0.91-1.35]) and those without CAD (27% versus 33%; aHR, 1.24 [95% CI, 0.97-1.57]). In comparison, presence and extent of CAD were associated with a relative 43% increased 10-year mortality (CAD versus no CAD, 55.0% versus 31.5%; aHR, 1.43 [95% CI, 1.25-1.64]). Compared with a matched general population, excess mortality risk was higher for patients with HF and CAD (54.7% versus 26.3%; aHR, 2.10 [95% CI, 1.85-2.39]) versus those with HF and no CAD (31.4% versus 17.2%; aHR, 1.76 [95% CI, 1.52-2.02]). CONCLUSIONS: Among newly diagnosed patients with HF and LVEF <50%, presence and extent of CAD are associated with substantial higher all-cause mortality risk than lower LVEF.

BACKGROUND: ST-segment elevation myocardial infarction (STEMI) is associated with high early mortality. However, it remains unclear if patients surviving the early phase have long-term excess mortality. OBJECTIVES: This study aims to assess excess mortality in STEMI patients treated with primary percutaneous coronary intervention (PCI) compared with an age- and- sex-matched general population at landmark periods 0 to 30 days, 31 to 90 days, and 91 days to 10 years. METHODS: Using the Western Denmark Heart Registry, we identified first-time PCI-treated patients who had primary PCI for STEMI from January 2003 to October 2018. Each patient was matched by age and sex to 5 individuals from the general population. RESULTS: We included 18,818 patients with first-time STEMI and 94,090 individuals from the general population. Baseline comorbidity burden was similar in STEMI patients and matched individuals. Compared with the matched individuals, STEMI was associated with a 5.9% excess mortality from 0 to 30 days (6.0% vs 0.2%; HR: 36.44; 95% CI: 30.86-43.04). An excess mortality remained present from 31 to 90 days (0.9% vs 0.4%; HR: 2.43; 95% CI: 2.02-2.93). However, in 90-day STEMI survivors, the absolute excess mortality was only 2.1 percentage points at 10-year follow-up (26.5% vs 24.5%; HR: 1.04; 95% CI: 1.01-1.08). Use of secondary preventive medications such as statins, antiplatelet therapy, and beta-blockers was very high in STEMI patients throughout 10-year follow-up. CONCLUSIONS: In primary PCI-treated STEMI patients with high use of guideline-recommended therapy, patients surviving the first 90 days had 10-year mortality that was only 2% higher than that of a matched general population.

BACKGROUND: Contemporary data on cardiovascular disease (CVD) risk in patients with newly diagnosed type 2 diabetes mellitus (T2DM) is needed to guide appropriate preventive management. OBJECTIVES: The authors sought to investigate sex- and age-specific 10-year CVD risk in patients with newly diagnosed T2DM compared with the general population. METHODS: A cohort study was conducted of all Danish patients with T2DM diagnosed between 2006 and 2013 (n = 142,587) and sex- and age-matched individuals from the general population (n = 388,410), all without prior atherosclerotic CVD. Ten-year CVD risk (myocardial infarction, stroke, and fatal CVD) was estimated. RESULTS: A total of 52,471 CVD events were recorded. Compared with the general population, the 10-year CVD risks were higher in patients with T2DM in both sexes and across all age groups, especially among younger individuals. For example, patients aged 40 to 49 years had the largest 10-year CVD risk difference (T2DM 6.1% vs general population 3.3%; risk difference: 2.8%, subdistribution HR: 1.91; 95% CI: 1.76-2.07). The age when a given CVD risk was reached differed substantially between the cohorts. Thus, a 10-year CVD risk of 5% was reached at age 43 in men with T2DM compared with 12 years later, at age 55, in men without T2DM. A 10-year CVD risk of 5% was reached at age 51 in women with T2DM and 10 years later, at age 61, in women without T2DM. CONCLUSIONS: Newly diagnosed T2DM increased 10-year CVD risk across both sexes and all age groups, especially among younger patients, with CVD occurring ≤12 years earlier than in general population individuals.

Purpose: To investigate the interplay between chronic kidney disease (CKD) and coronary artery disease (CAD) on the incidence of cardiovascular events in patients with suspected chronic coronary syndrome (CCS). Patients and Methods: Patients with suspected CCS who underwent first-time coronary angiography in Western Denmark between 2003 and 2016 were included in this cohort study. Moreover, an age- and sex-matched general population cohort was established. Patients were stratified according to estimated glomerular filtration rate (eGFR). Presence of CAD was defined as ≥1 obstructive stenosis or non-obstructive diffuse disease. Major adverse cardiovascular events (MACE) were defined as a composite of myocardial infarction, ischemic stroke, and cardiac death. Results: A total of 42,611 patients were included with a median follow-up of 7.3 years. Patients without and with CAD had MACE rates per 100 person-years that were 0.52 and 1.67 for eGFR ≥90 mL/min/1.73 m2, 0.68 and 2.09 for eGFR 60-89 mL/min/1.73 m2, 1.27 and 3.85 for eGFR 30-59 mL/min/1.73 m2, and 2.27 and 6.92 for eGFR <30 mL/min/1.73 m2. Comparing to eGFR ≥90 mL/min/1.73 m2, the adjusted incidence rate ratios for MACE were 1.29 (1.10-1.51) for eGFR 60-89 mL/min/1.73 m2, 1.86 (1.49-2.33) for eGFR 30-59 mL/min/1.73 m2, and 3.57 (1.92-6.67) for eGFR <30 mL/min/1.73 m2 in patients without CAD, and 1.11 (1.03-1.20), 1.71 (1.55-1.90), and 2.46 (1.96-3.09) in patients with CAD. The inverse relationship between kidney function and risk of MACE was confirmed when comparing patients with and without CAD to matched individuals in the general population. Conclusion: Absence of CAD is a strong negative predictor of major adverse cardiovascular events in patients with CKD.
RESUMEN
BACKGROUND: Observational studies have reported that mortality rates after ST-segment elevation myocardial infarction (STEMI) have been stable since 2006 to 2010. OBJECTIVES: The aim of this study was to evaluate the temporal trends in 1-year, 30-day, and 31- to 365-day mortality after STEMI in Western Denmark where primary percutaneous coronary intervention (PCI) has been the national reperfusion strategy since 2003. METHODS: Using the Western Denmark Heart Registry, the study identified first-time PCI-treated patients undergoing primary PCI (pPCI) for STEMI from 2003 to 2018. Based on the year of pPCI, patients were divided into 4 time-interval groups and followed up for 1 year using the Danish national health registries. RESULTS: A total of 19,613 patients were included. Median age was 64 years, and 74% were male. One-year mortality decreased gradually from 10.8% in 2003-2006, 10.4% in 2007-2010, 9.1% in 2011-2014, to 7.7% in 2015-2018 (2015-2018 vs 2003-2006: adjusted HR [aHR]: 0.71; 95% CI: 0.62-0.82). The largest absolute mortality decline occurred in the 0- to 30-day period with a 2.3% reduction (aHR: 0.69; 95% CI: 0.59-0.82), and to a lesser extent in the 31- to 365-day period (risk reduction: 1.0%; aHR: 0.71; 95% CI: 0.56-0.90). CONCLUSIONS: In a high-income European country with a fully implemented pPCI strategy, 1-year mortality in pPCI-treated patients with STEMI decreased substantially between 2003 and 2018. Approximately three-quarters of the absolute mortality reduction occurred within the first 30 days after pPCI. These results indicate that optimization of early management of pPCI-treated patients with STEMI offers great opportunities for improving overall survival in contemporary clinical practice.

AIMS: Beyond 1 year after percutaneous coronary intervention (PCI), guidelines recommend anticoagulant monotherapy in patients with atrial fibrillation (AF) rather than dual therapy with an anticoagulant and an antiplatelet drug. The risks and benefits of this strategy, however, remain uncertain. We examined hospitalization for bleeding and ischaemic risk beyond 1 year after PCI in patients with AF treated with monotherapy vs. dual therapy. Furthermore, among patients treated with monotherapy, we compared direct oral anticoagulant (DOAC) therapy and vitamin K antagonist (VKA) therapy. METHODS AND RESULTS: We included all patients with AF undergoing first-time PCI between 2003 and 2017 from the Western Denmark Heart Registry and followed them for up to 4 years. Follow-up started 15 months after PCI to enable assessment of medical treatment after 12 months. Using a Cox regression model, we computed weighted hazard ratios (HRw) of hospitalization for bleeding and major adverse cardiac events (MACEs). Analyses comparing monotherapy vs. dual therapy included 3331 patients, and analyses comparing DOAC vs. VKA monotherapy included 1275 patients. Risks of hospitalization for bleeding [HRw 0.90, 95% confidence interval (CI) 0.75-1.09] and MACE (HRw 1.04, 95% CI 0.90-1.19) were similar with monotherapy and dual therapy. Similarly, risks of hospitalization for bleeding (HRw 1.27, 95% CI 0.84-1.92) and MACE (HRw 1.15, 95% CI 0.87-1.50) were equal with DOAC and VKA monotherapy. CONCLUSION: Our results support long-term OAC monotherapy beyond 1 year after PCI in patients with atrial fibrillation and suggest that DOAC monotherapy is as safe and effective as VKA monotherapy.

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 (from 5% to 50%) and multiple antihypertensive drugs (from 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.

AIMS: To examine combined and sex-specific temporal changes in risks of adverse cardiovascular events and coronary revascularization in patients with chronic coronary syndrome undergoing coronary angiography. METHODS AND RESULTS: We included all patients with stable angina pectoris and coronary artery disease examined by coronary angiography in Western Denmark from 2004 to 2016. Patients were stratified by examination year interval: 2004-2006, 2007-2009, 2010-2012, and 2013-2016. Outcomes were 2-year risk of myocardial infarction, ischaemic stroke, cardiac death, and all-cause death estimated by adjusted incidence rate ratios using patients examined in 2004-2006 as reference. A total of 29 471 patients were included, of whom 70% were men. The 2-year risk of myocardial infarction [2.8% vs. 1.9%, adjusted incidence rate ratio 0.65, 95% confidence interval (CI) 0.53-0.81], ischaemic stroke (1.8% vs. 1.1%, adjusted incidence rate ratio 0.48, 95% CI 0.37-0.64), cardiac death (2.1% vs. 0.9%, adjusted incidence rate ratio 0.38, 95% CI 0.29-0.51), and all-cause death (5.0% vs. 3.6%, adjusted incidence rate ratio 0.65, 95% CI 0.55-0.76) decreased from the first examination interval (2004-2006) to the last examination interval (2013-2016). Coronary revascularizations also decreased (percutaneous coronary intervention: 51.6% vs. 42.5%; coronary artery bypass grafting: 24.6% vs. 17.5%). Risk reductions were observed in both men and women, however, women had a lower absolute risk. CONCLUSION: The risk for adverse cardiovascular events decreased substantially in both men and women with chronic coronary syndrome from 2004 to 2016. These results most likely reflect the cumulative effect of improvements in the management of chronic coronary artery disease.

BACKGROUND: Ticagrelor was introduced in Denmark in 2011 after randomised data showed its superiority over clopidogrel for patients with acute coronary syndrome (ACS). We assessed the effectiveness and safety of ticagrelor implementation in ACS patients undergoing percutaneous coronary intervention (PCI). METHODS: We identified PCI-treated ACS patients in Western Denmark who redeemed a P2Y12 inhibitor prescription within 14 days. Using Danish health registries, 1-year outcomes were compared before (2007-2010) and after (2012-2015) introduction of ticagrelor. Outcomes were MACE (death, myocardial infarction, and ischaemic stroke) and hospitalisation for bleeding. Inverse probability of treatment weights were used to estimate weighted incidence rate ratios (wIRRs). FINDINGS: We included 14,450 patients; 7,102 were treated in the earlier time period (99·9% clopidogrel) and 7,348 in the later time period (87·8% ticagrelor). Ticagrelor implementation was not associated with a clinically relevant difference in 1-year risk of MACE with 413 events in the ticagrelor period vs. 424 events in the clopidogrel period (cumulative incidence percentage [CIP] 5·6% vs. 6·0%; wIRR 1·06, 95% CI 0·92-1·22). The 1-year risk of bleeding was also similar between groups with 335 bleedings requiring hospitalisation in the ticagrelor period vs. 309 events in the clopidogrel period (CIP 4·6% vs. 4·4%; wIRR 1·05, 95% CI 0·89-1·23). Results were robust in patients above and below 70 years of age. INTERPRETATION: Implementation of ticagrelor was not associated with changes in risks of ischaemic or bleeding events in Danish PCI-treated ACS patients.
RESUMEN
INTRODUCTION: Patients with diabetes have increased risk of lower limb revascularization and amputation due to higher risk of peripheral artery disease (PAD) and peripheral neuropathy. The additive effect of coronary artery disease (CAD) is less clear. We examined the risk of PAD, lower limb revascularization, and amputation in diabetes and non-diabetes patients with and without CAD in patients examined by coronary angiography (CAG). RESEARCH DESIGN AND METHODS: We included all patients undergoing CAG between 2003 and 2016 in Western Denmark. Patients with previous CAD, PAD, lower limb revascularization, or amputation were excluded. Patients were stratified by diabetes and CAD status and followed for a maximum of 10 years. Outcomes were PAD, lower limb revascularization, and amputation. We estimated 10-year cumulative incidences and adjusted HRs (aHRs) using patients neither diabetes nor CAD as reference. RESULTS: A total of 118 787 patients were included, of whom 41 878 (35%) had neither diabetes nor CAD, 5735 (5%) had diabetes alone, 59 427 (50%) had CAD alone, and 11 747 (10%) had both diabetes and CAD. Median follow-up was 6.9 years. Diabetes patients without CAD had higher risk of PAD (3.5%, aHR 1.73, 95% CI 1.51 to 1.97), lower limb revascularization (1.6%, aHR 1.55, 95% CI 1.16 to 2.05), and lower limb amputation (2.4%, aHR 5.51, 95% CI 4.09 to 7.43) compared with patients with neither diabetes nor CAD. CAD was associated with 2.5-fold and 1.8-fold higher risk of PAD and amputation, respectively, among patients without diabetes, and associated with 3.9-fold and 9.5-fold higher risk of PAD and lower limb amputation among patients with diabetes. CONCLUSIONS: Despite absence of obstructive CAD, patients with diabetes remained at higher risk of PAD, lower limb revascularization, and lower limb amputation. Diabetes was more strongly associated with amputation than CAD, but CAD exacerbated the risks of PAD, revascularization, and amputation in patients with diabetes.

OBJECTIVE: Trends in cardiac risk and death have not been examined in patients with incident type 2 diabetes and no prior cardiovascular disease. Therefore, we aimed to examine trends in cardiac risk and death in relation to the use of prophylactic cardiovascular medications in patients with incident type 2 diabetes without prior cardiovascular disease. RESEARCH DESIGN AND METHODS: In this population-based cohort study, we included patients with incident type 2 diabetes between 1996 and 2011 through national health registries. Each patient was matched by age and sex with up to five individuals without diabetes from the general population. All individuals were followed for 7 years. RESULTS: We identified 209,311 patients with incident diabetes. From 1996-1999 to 2008-2011, the 7-year risk of myocardial infarction decreased from 6.9 to 2.8% (adjusted hazard ratio [aHR] 0.39 [95% CI 0.37-0.42]), cardiac death from 7.1 to 1.6% (aHR 0.23 [95% CI 0.21-0.24]), and all-cause death from 28.9 to 16.8% (aHR 0.68 [95% CI 0.66-0.69]). Compared with the general population, 7-year risk differences decreased from 3.3 to 0.8% for myocardial infarction, from 2.7 to 0.5% for cardiac death, and from 10.6 to 6.0% for all-cause death. Use of cardiovascular medications within ±1 year of diabetes diagnosis, especially statins (5% of users in 1996-1999 vs. 60% in 2008-2011), increased during the study period. CONCLUSIONS: From 1996 to 2011, Danish patients with incident type 2 diabetes and no prior cardiovascular disease experienced major reductions in cardiac risk and mortality. The risk reductions coincided with increased use of prophylactic cardiovascular medications.
RESUMEN
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.
