Diabetes mellitus (DM) is a known risk factor for myocardial infarction (MI); however, data regarding MI subtypes in people with diabetes are limited. In the Liraglutide Effect and Action in Diabetes: Evaluation of Cardiovascular Outcome Results (LEADER) trial (n = 9,340), liraglutide significantly reduced the risk of major adverse cardiovascular (CV) events (composite of CV death, nonfatal MI, or nonfatal stroke) versus placebo in patients with type 2 DM and high CV risk. Liraglutide also reduced risk of first MI (292 events with liraglutide vs 339 with placebo). This post hoc analysis characterized MIs (first and recurrent) occurring in LEADER, by treatment arm and regarding incidence, outcome, subtype, and troponin levels. A total of 780 MIs (first and recurrent) were reported, with fewer in the liraglutide-treatment group than in the placebo-treatment group (359 vs 421, p = 0.022). Numerically fewer MIs were associated with CV death with liraglutide than with placebo (17 vs 28 fatal MIs, p = 0.28). Symptomatic MIs in both arms were mainly non–ST-segment elevation MI (555/641) and spontaneous MI (518/641). Numerically greater proportions of symptomatic MIs were associated with troponin levels ≤5× or ≤10× the upper reference limit with liraglutide versus placebo (p = 0.16 and p = 0.42, respectively). At baseline, more liraglutide-treated patients than placebo-treated patients with MI during the trial had a history of coronary artery bypass graft (p = 0.008), and fewer had peripheral arterial disease in the lower extremities (p = 0.005) and >50% stenosis of the coronary artery, the carotid artery, or other arteries (p = 0.044). In conclusion, this analysis showed that liraglutide reduces the incidence of MIs in patients with type 2 DM at high CV risk and may impact the clinical outcomes of MI.

Prior studies in patients with noncomplex coronary artery disease have demonstrated the safety of percutaneous coronary intervention (PCI) in the outpatient setting. We sought to examine the outcomes of outpatient PCI in patients with unprotected left main coronary artery disease (LMCAD). In the EXCEL trial, 1905 patients with LMCAD and site-assessed low or intermediate SYNTAX scores were randomized to PCI with everolimus-eluting stents versus coronary artery bypass grafting. The primary end point was major adverse cardiovascular events (MACE; the composite of death, stroke, or myocardial infarction). In this sub-analysis, outcomes at 30 days and 5 years were analyzed according to whether PCI was performed in the outpatient versus inpatient setting. Among 948 patients with LMCAD assigned to PCI, 935 patients underwent PCI as their first procedure, including 100 (10.7%) performed in the outpatient setting. Patients who underwent outpatient compared with inpatient PCI were less likely to have experienced recent myocardial infarction. Distal left main bifurcation disease involvement and SYNTAX scores were similar between the groups. Comparing outpatient to inpatient PCI, there were no significant differences in MACE at 30 days (4.0% vs 5.0% respectively, adjusted OR 0.52 95% CI 0.12 to 2.22; p = 0.38) or 5 years (20.6% vs 22.1% respectively, adjusted OR 0.72, 95% CI 0.40 to 1.29; p = 0.27). Similar results were observed in patients with distal left main bifurcation lesions. In conclusion, in the EXCEL trial, outpatient PCI of patients with LMCAD was not associated with an excess early or late hazard of MACE. These data suggest that outpatient PCI may be safely performed in select patients with LMCAD.

It is still controversial whether baseline thrombocytopenia is independently associated with adverse events after percutaneous coronary intervention. We evaluated the influence of baseline thrombocytopenia against ischemic, bleeding and mortality among the 19,353 patients whose baseline platelet counts were available in the pooled database from the 3 studies in Japan. Baseline thrombocytopenia was classified as follows: mild, ≥100 and <150 × 109/L; moderate, ≥50 and <100 × 109/L; and severe, <50 × 109/L. Primary ischemic outcome measure was defined as composite of myocardial infarction and ischemic stroke, and primary bleeding outcome measure was defined by the Global Utilization of Streptokinase and Tissue Plasminogen Activator for Occluded arteries trial as moderate or severe bleeding. There were 2,590 patients (13.4%) with baseline thrombocytopenia comprising 292 patients (1.5%) with moderate/severe (moderate: 277 and severe: 15) thrombocytopenia and 2,298 patients (11.9%) with mild thrombocytopenia, whereas 16,763 patients (86.6%) had no thrombocytopenia. During 3-year follow-up, the adjusted risks of moderate/severe and mild thrombocytopenia relative to none were neutral for primary ischemic outcome (hazard ratio [HR] 1.07 [95% confidence interval [CI] 0.72 to 1.60], p = 0.74, and HR 0.93 [0.79 to 1.09], p = 0.37, respectively) but were significantly higher for primary bleeding outcome (HR 2.35 [1.80 to 3.08], p <0.001, and HR 1.20 [1.03 to 1.40], p = 0.02), and for mortality (HR 2.34 [1.87 to 2.93], p <0.001, and HR 1.26 [1.11 to 1.43], p <0.001). In conclusion, patients with baseline thrombocytopenia, even a mild one, had a higher risk of bleeding events and all-cause death, but not for ischemic events after percutaneous coronary intervention.

In a multicenter trial, 20,332 patients who had recently had an ischemic stroke were randomly assigned to receive either telmisartan or placebo. All patients also received medications for blood-pressure control at the investigators' discretion. At a mean follow-up of 2.5 years, there was no significant difference between the two study groups in the rates of recurrent stroke or major cardiovascular events. Patients who had recently had an ischemic stroke were randomly assigned to receive either telmisartan or placebo. At a mean follow-up of 2.5 years, there was no significant difference between the study groups in the rates of recurrent stroke or major cardiovascular events. Stroke is the second most frequent cause of death in the world and is responsible for about 5 million deaths each year. 1 An additional 15 million persons have nonfatal strokes, with about a third having disabling consequences. Elevated blood pressure is the strongest risk factor for stroke, and lowering of blood pressure, especially in patients with substantially elevated levels (e.g., systolic pressure, >160 mm Hg), reduces the risk of stroke. 2 After a stroke, lowering blood pressure with a combination of an angiotensin-converting–enzyme (ACE) inhibitor and a diuretic reduced rates of recurrent stroke in the Perindopril Protection against Recurrent Stroke Study . . .

Cardiac rupture (CR) is a fatal complication of ST-elevation myocardial infarction (STEMI) with poor prognosis. The aim of this study was to develop and validate practical risk score to predict the CR after STEMI. A total of 11,234 STEMI patients from 7 centers in China were enrolled in our study, we firstly developed a simplified fast-track CR risk model from 7455 STEMI patients, and then prospectively validated the CR risk model using receiver-operating characteristic (ROC) curves by the other 3779 consecutive STEMI patients. This trial is registered with ClinicalTrials.gov, number NCT02484326. The incidence of CR was 2.12% (238/11,234), and the thirty-day mortality in CR patients was 86%. We developed a risk model which had 7 independent baseline clinical predictors (female sex, advanced age, anterior myocardial infarction, delayed admission, heart rate, elevated white blood cell count and anemia). The CR risk score system differentiated STEMI patients with incidence of CR ranging from 0.2% to 13%. The risk score system demonstrated good predictive value with area under the ROC of 0.78 (95% CI 0.73–0.84) in validation cohort. Primary percutaneous coronary intervention decreased the incidence of CR in high risk group (3.9% vs. 6.2%, p<0.05) and very high risk group (8.0% vs. 15.2%, p<0.05). A simple risk score system based on 7 baseline clinical variables could identify patients with high risk of CR, for whom appropriate treatment strategies can be implemented.

Low serum albumin (SA) on admission in patients with acute myocardial infarction (AMI) has been reported to be associated with adverse cardiovascular events. The relation between low SA and post-AMI bleeding events is presently unknown. We analyzed 1,724 patients with AMI enrolled in the HAGAKURE-ACS registry who underwent primary percutaneous coronary intervention from January 2014 to December 2018. To assess the influence of low SA at admission, patients were divided into 3 groups according to the albumin tertiles: the low SA group (<3.8 g/100 ml), the middle SA (MSA) group (3.8 to 4.1 g/100 ml), and the normal SA (NSA) group (≥4.2 g/100 ml). The primary end point was the incidence of Global Utilization of Streptokinase and Tissue Plasminogen Activator for Occluded Coronary Arteries moderate/severe bleeding. The cumulative 3-year incidence of the primary end point was significantly higher in the low SA group than in the MSA and NSA groups (30.8% and 11.9% vs 7.7%; p <0.001). In the landmark analysis at 30 days, the cumulative incidences of the primary end point were also significantly higher in the low SA group than in the MSA and NSA groups, both within and beyond 30 days (20.1% and 6.1% vs 3.5%; p <0.001, and 12.4% and 6.2% vs 4.5%; p <0.001, respectively). After adjusting for confounders, the low SA group showed excess risk of bleeding events relative to NSA (hazard ratio 1.56; 95% confidence interval 1.06 to 2.30; p = 0.026), whereas risk of bleeding was neutral in MSA relative to NSA (hazard ratio 0.94; 95% confidence interval 0.63 to 1.34; p = 0.752). In conclusion, low SA at admission was independently associated with higher risk for bleeding events in patients with AMI undergoing percutaneous coronary intervention.

ObjectivePrior data have shown rising acute myocardial infarction (MI) trends in Australia; whether these increases have continued in recent years is not known. This study thus sought to characterise contemporary nationwide trends in MI hospitalisations and coronary procedures in Australia and their associated economic burden.MethodsThe primary outcome measure was the incidence and time trends of total MI, ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI) hospitalisations from 1993 to 2017. The incidence and time trends of coronary procedures were additionally collected, alongside MI hospitalisation costs.ResultsAdjusted for population changes, annual MI incidence increased from 216.2 cases per 100 000 to a peak of 270.4 in 2007 with subsequent decline to 218.7 in 2017. Similarly, NSTEMI incidence increased from 68.0 cases per 100 000 in 1993 to a peak of 192.6 in 2007 with subsequent decline to 162.6 in 2017. STEMI incidence decreased from 148.3 cases per 100 000 in 1993 to 56.2 in 2017. Across the study period, there were annual increases in MI hospitalisations of 0.7% and NSTEMI hospitalisations of 5.6%, and an annual decrease in STEMI hospitalisations of 4.8%. Angiography and percutaneous coronary intervention increased by 3.4% and 3.3% annually, respectively, while coronary artery bypass graft surgery declined by 2.2% annually. MI hospitalisation costs increased by 100% over the study period, despite a decreased average length of stay by 45%.ConclusionsThe rising incidence of MI hospitalisations appear to have stabilised in Australia. Despite this, associated healthcare expenditure remains significant, suggesting a need for continual implementation of public health policies and preventative strategies.

Glycoprotein IIb/IIIa inhibitors are used routinely in patients with acute coronary syndromes who are undergoing invasive procedures, but the optimal timing of administration is unknown. The early, routine use of eptifibatide was found to be no better than the delayed, provisional use of the drug and was associated with more bleeding. The early, routine use of eptifibatide was found to be no better than the delayed, provisional use of the drug and was associated with more bleeding. The optimal timing for the initiation of treatment with glycoprotein IIb/IIIa inhibitors in patients who have acute coronary syndromes without ST-segment elevation and are undergoing invasive procedures has not been determined. It is also not clear whether such treatment should be administered routinely to all such patients before the procedure or whether such treatment should be provisional. The 2007 guidelines of the American College of Cardiology and the American Heart Association 1 recommend that patients with high-risk features receive aspirin and either clopidogrel or a glycoprotein IIb/IIIa inhibitor before angiography (i.e., early therapy) (class I recommendation).

In this large clinical trial, aspirin plus extended-release dipyridamole was found to have an efficacy similar to that of clopidogrel in the prevention of recurrent stroke. However, aspirin plus extended-release dipyridamole resulted in more bleeding, including intracranial bleeding. The results will help guide therapy for secondary stroke prevention. Aspirin plus extended-release dipyridamole was found to have an efficacy similar to that of clopidogrel in the prevention of recurrent stroke. However, aspirin plus extended-release dipyridamole resulted in more bleeding, including intracranial bleeding. Recurrent stroke is an important vascular event affecting the life of survivors of ischemic stroke. 1 Multiple randomized trials have proved the efficacy of antiplatelet agents for the prevention of recurrent stroke after noncardioembolic stroke. 2 – 11 Antiplatelet options for the prevention of recurrent stroke include aspirin (50 mg to 325 mg per day), the combination of low-dose aspirin and extended-release dipyridamole, and clopidogrel alone. 12 , 13 Aspirin has been shown to reduce the risk of stroke recurrence by about 23% as compared with placebo. 7 Studies of clopidogrel have suggested an 8% relative risk reduction of stroke recurrence, as compared with aspirin, among . . .
