Randomized Controlled Trial Multicenter Study Comparative StudyTemporal changes in emergency department triage of patients with acute myocardial infarction and the effect on outcomes.
All patients who present to an emergency department (ED) are triaged. The ED triage score may determine when patients are seen by a physician. Half of patients with acute myocardial infarction (AMI) were given a low priority score in Ontario in 2000/2001. We assessed the appropriateness of ED triage and its association with quality indicators and outcomes in a more recent AMI cohort and compared this with previous findings. ⋯ Emergency department triage of patients with AMI improved substantially over 5 years. For the third of patients with AMI who continue to receive a low priority score, including 25% of patients with STEMI, the associated delays in diagnosis and therapy were greater than previously and were associated with increased hospital LOS and mortality. Given the impact of this initial, cursory assessment, hospital systems should consider monitoring the quality of their ED triage.

Randomized Controlled Trial Multicenter Study Comparative StudyColchicine prevents early postoperative pericardial and pleural effusions.
No preventive pharmacologic strategies have been proven efficacious for the prevention of postoperative effusions after cardiac surgery. Colchicine is safe and efficacious for the prevention of pericarditis. On this basis, we realized a substudy of the COPPS trial to assess the efficacy and safety of colchicine for the prevention of postoperative pericardial and pleural effusions. ⋯ Colchicine is safe and efficacious for the primary prevention of postoperative effusions after cardiac surgery.

Multicenter Study Comparative Study Clinical TrialBerlin Heart EXCOR Pediatric ventricular assist device Investigational Device Exemption study: study design and rationale.
Currently, there are no Food and Drug Administration-approved devices available that can provide long-term mechanical circulatory support to smaller children with severe heart failure as a bridge to heart transplant (HT). In recent years, the Berlin Heart EXCOR Pediatric ventricular assist device (VAD) has emerged as a potential treatment option. Systematic data on the safety and efficacy of the EXCOR are limited. ⋯ The Berlin Heart IDE clinical study will be the first bridge-to-HT VAD study designed exclusively for children. It is anticipated that the study will provide important information on the safety and efficacy of the Berlin Heart EXCOR Pediatric in children while providing valuable lessons into the design and conduct of future VAD studies in children.

Randomized Controlled Trial Multicenter Study Comparative StudyTemporal changes in the management and outcome of Canadian diabetic patients hospitalized for non-ST-elevation acute coronary syndromes.
There are limited data on the contemporary management and outcomes of non-ST-elevation acute coronary syndrome (NSTE-ACS) patients with diabetes in the "real world." We sought to evaluate (1) the temporal changes in the medical and invasive management and (2) in-hospital outcome of NSTE-ACS patients with and without diabetes. ⋯ Over the last decade, NSTE-ACS patients with diabetes continue to be treated more conservatively, despite evidence that they would derive similar or even greater benefits from aggressive treatment. This underutilization of evidence-based therapies among diabetic patients with NSTE-ACS in the "real world" may partly explain their worse outcome.

Randomized Controlled Trial Multicenter Study Comparative StudyRapid complete reversal of systemic hypoperfusion after intra-aortic balloon pump counterpulsation and survival in cardiogenic shock complicating an acute myocardial infarction.
In patients with cardiogenic shock (CS) complicating an acute myocardial infarction, a strategy of early revascularization (ERV) versus initial medical stabilization (IMS) improves survival. Intra-aortic balloon counterpulsation (IABC) provides hemodynamic support and facilitates coronary angiography and revascularization in CS patients. ⋯ In CS patients, CRH after commencing IABC was independently associated with improved in-hospital, 30-day and 1-year survival regardless of early revascularization. In CS patients, CRH with IABC is an important early prognostic feature.
