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.

Randomized Controlled TrialImpact of completeness of revascularization on long-term cardiovascular outcomes in patients with type 2 diabetes mellitus: results from the Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D).
Patients with diabetes have more extensive coronary disease than those without diabetes, resulting in more challenging percutaneous coronary intervention or surgical (coronary artery bypass graft) revascularization and more residual jeopardized myocardium. The Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) trial provided an opportunity to examine the long-term clinical impact of completeness of revascularization in patients with diabetes. ⋯ URL: http://www.clinicaltrials.gov.

Randomized Controlled Trial Comparative StudyEffects of hydration in contrast-induced acute kidney injury after primary angioplasty: a randomized, controlled trial.
Intravascular volume expansion represents a beneficial measure against contrast-induced acute kidney injury (CI-AKI) in patients undergoing elective angiographic procedures. However, the efficacy of this preventive strategy has not yet been established for patients with ST-elevation-myocardial infarction (STEMI), who are at higher risk of this complication after primary percutaneous coronary intervention (PCI). In this randomized study we investigated the possible beneficial role of periprocedural intravenous volume expansion and we compared the efficacy of 2 different hydration strategies in patients with STEMI undergoing primary PCI. ⋯ Adequate intravenous volume expansion may prevent CI-AKI in patients undergoing primary PCI. A regimen of preprocedure and postprocedure hydration therapy with sodium bicarbonate appears to be more efficacious than postprocedure hydration only with isotonic saline.

Randomized Controlled TrialAdding cilostazol to dual antiplatelet therapy achieves greater platelet inhibition than high maintenance dose clopidogrel in patients with acute myocardial infarction: Results of the adjunctive cilostazol versus high maintenance dose clopidogrel in patients with AMI (ACCEL-AMI) study.
Optimal platelet inhibition is an important therapeutic adjunct in patients acute myocardial infarction (AMI) undergoing coronary stenting. Whether adjunctive cilostazol to dual antiplatelet therapy (triple antiplatelet therapy) can inhibit enhanced platelet reactivity in patients with AMI yet has not been determined. The aim of this study was to assess the degree of platelet inhibition by triple antiplatelet therapy in patients with AMI. ⋯ Among patients with AMI undergoing coronary stenting, triple antiplatelet therapy results in a greater antiplatelet effect at 30 days as compared with a high-MD clopidogrel or standard dual antiplatelet therapy.

Randomized Controlled Trial Comparative StudyImpact of femoral vascular closure devices and antithrombotic therapy on access site bleeding in acute coronary syndromes: The Acute Catheterization and Urgent Intervention Triage Strategy (ACUITY) trial.
The Acute Catheterization and Urgent Intervention Triage Strategy (ACUITY) trial demonstrated that bivalirudin monotherapy significantly reduces major bleeding compared with heparin (unfractionated or enoxaparin) or bivalirudin plus a glycoprotein IIb/IIIa inhibitor in acute coronary syndromes. Whether vascular closure devices (VCD) impact these results is unknown. Therefore, this study sought to determine whether VCD impact major access site bleeding (ASB) in patients with acute coronary syndromes undergoing early invasive management by the femoral approach. ⋯ In patients with acute coronary syndromes undergoing an early invasive management strategy by the femoral approach, the use of a VCD, bivalirudin monotherapy, or both minimizes rates of major ASB.
