Multicenter StudyIncidence and outcome of surgical procedures after coronary bare-metal and drug-eluting stent implantation: a report from the CREDO-Kyoto PCI/CABG registry cohort-2.
There still remain safety concerns on surgical procedures after coronary drug-eluting stents (DES) implantation, and optimal management of perioperative antiplatelet therapy (APT) has not been yet established. ⋯ Surgical procedures were commonly performed after coronary stent implantation, and the risk of ischemic and bleeding complications in surgical procedures was low. In patients selected to receive DES or BMS, there were no differences in outcomes. Perioperative administration of dual-APT was not associated with lower risk for ischemic events.

Randomized Controlled Trial Multicenter StudyPrognostic significance of elevated baseline troponin in patients with acute coronary syndromes and chronic kidney disease treated with different antithrombotic regimens: a substudy from the ACUITY trial.
Elevation of baseline cardiac troponin in patients presenting with acute coronary syndromes (ACS) confers an adverse prognosis. The prognostic value of troponin elevation in patients with chronic kidney disease (CKD) and ACS is less certain. ⋯ URL: http://www.clinicaltrials.gov. Unique identifier: NCT00093158.

Multicenter StudyPrehospital 12-lead ECG to triage ST-elevation myocardial infarction and emergency department activation of the infarct team significantly improves door-to-balloon times: ambulance Victoria and MonashHEART Acute Myocardial Infarction (MonAMI) 12-lead ECG project.
American College of Cardiology/American Heart Association guidelines recommend >75% of patients with an ST-elevation myocardial infarction receive primary percutaneous coronary interventions (PPCI) within 90 minutes. Despite these recommendations, this goal has been difficult to achieve. ⋯ The performance of prehospital 12-lead ECG triage and emergency department activation of the infarct team significantly improves D2BT and results in a greater proportion of patients achieving guideline recommendations.

Randomized Controlled Trial Multicenter StudyEffect of supersaturated oxygen delivery on infarct size after percutaneous coronary intervention in acute myocardial infarction.
Myocardial salvage is often suboptimal after percutaneous coronary intervention in ST-segment elevation myocardial infarction. Posthoc subgroup analysis from a previous trial (AMIHOT I) suggested that intracoronary delivery of supersaturated oxygen (SSO(2)) may reduce infarct size in patients with large ST-segment elevation myocardial infarction treated early. ⋯ Among patients with anterior ST-segment elevation myocardial infarction undergoing percutaneous coronary intervention within 6 hours of symptom onset, infusion of SSO(2) into the left anterior descending artery infarct territory results in a significant reduction in infarct size with noninferior rates of major adverse cardiovascular events at 30 days.

Multicenter StudyThirty-day outcomes for carotid artery stenting in 6320 patients from 2 prospective, multicenter, high-surgical-risk registries.
The American Heart Association has established guidelines for acceptable 30-day death and stroke rates for patients with severe carotid disease undergoing standard-risk carotid endarterectomy: <3% for asymptomatic lesions and <6% for symptomatic lesions. To date, carotid artery stenting has not demonstrated these outcomes in multicenter, prospective assessments of high-surgical-risk patients. ⋯ Outcomes for carotid artery stenting in nonoctogenarian high-surgical-risk patients have improved since the pivotal Food and Drug Administration approval trials, and have achieved American Heart Association standards in both symptomatic and asymptomatic lesions.
