Randomized Controlled Trial Multicenter StudyEffect of alirocumab, a monoclonal antibody to PCSK9, on long-term cardiovascular outcomes following acute coronary syndromes: rationale and design of the ODYSSEY outcomes trial.
Following acute coronary syndrome (ACS), the risk for future cardiovascular events is high and is related to levels of low-density lipoprotein cholesterol (LDL-C) even within the setting of intensive statin treatment. Proprotein convertase subtilisin/kexin type 9 (PCSK9) regulates LDL receptor expression and circulating levels of LDL-C. Antibodies to PCSK9 can produce substantial and sustained reductions of LDL-C. The ODYSSEY Outcomes trial tests the hypothesis that treatment with alirocumab, a fully human monoclonal antibody to PCSK9, improves cardiovascular outcomes after ACS. ⋯ ODYSSEY Outcomes will determine whether the addition of the PCSK9 antibody alirocumab to intensive statin therapy reduces cardiovascular morbidity and mortality after ACS.

Randomized Controlled Trial Multicenter StudyRationale and design of a double-blind, multicenter, randomized, placebo-controlled clinical trial of early administration of intravenous β-blockers in patients with ST-elevation myocardial infarction before primary percutaneous coronary intervention: EARLY β-blocker administration before primary PCI in patients with ST-elevation myocardial infarction trial.
β-Blockers have a class 1a recommendation in the treatment of patients with ST-elevation myocardial infarctions (STEMIs), as they are associated with a reduced mortality, recurrent myocardial infarction, life-threatening arrhythmias, and with prevention of unfavorable left ventricular remodeling. Whether early administration before primary percutaneous coronary intervention (PCI) of intravenous β-blockers reduces the infarct size in the current era is unknown. ⋯ The EARLY-BAMI trial is a multinational, multicenter, double-blind, placebo-controlled, randomized clinical trial that will investigate the impact of intravenous metoprolol administration before primary PCI for STEMI on myocardial infarct size as measured with MRI at 30 days.

Randomized Controlled TrialSevoflurane in acute myocardial infarction: a pilot randomized study.
Experimental evidence suggests that the inhalational anesthetic sevoflurane has a cardioprotective effect. Our objective was to determine if sedation with sevoflurane will reduce infarct size in patients with acute myocardial infarction (MI) who are treated with primary percutaneous coronary intervention (PCI). ⋯ Sevoflurane administration during primary PCI did not reduce infarct size. There was a trend toward a reduction in infarct size among patients with anterior MI. Sevoflurane administration was associated with improvement in ST-segment resolution.

Randomized Controlled TrialThe palliative care in heart failure trial: rationale and design.
The progressive nature of heart failure (HF) coupled with high mortality and poor quality of life mandates greater attention to palliative care as a routine component of advanced HF management. Limited evidence exists from randomized, controlled trials supporting the use of interdisciplinary palliative care in HF. ⋯ PAL-HF is a randomized, controlled clinical trial that will help evaluate the efficacy and cost effectiveness of palliative care in advanced HF using a patient-centered outcome as well as clinical and economic end points.

The association of myocardial infarction process of care measures and in-hospital mortality: a report from the NCDR®.
The Center for Medicare and Medicaid Services (CMS) publicly reports "core process of care measures" along with 30-day mortality rates for patients with acute myocardial infarction; the American College of Cardiology/American Heart Association has a similar but expanded set of performance measures. ⋯ Although process performance was associated with hospital mortality, the association was low for STEMI and nonsignificant for NSTEMI hospitals, thus supporting the need to measure complementary metrics of acute myocardial infarction quality of care.
