Randomized Controlled Trial Multicenter Study Comparative StudyCanada Acute Coronary Syndrome Risk Score: a new risk score for early prognostication in acute coronary syndromes.
Despite the availability of several acute coronary syndrome (ACS) prognostic risk scores, there is no appropriate score for early-risk stratification at the time of the first medical contact with patients with ACS. The primary objective of this study is to develop a simple risk score that can be used for early-risk stratification of patients with ACS. ⋯ The C-ACS risk score permits rapid stratification of patients with ACS. Because this risk score is simple and easy to memorize and calculate, it can be rapidly applied by health care professionals without advanced medical training.

Multicenter Study Comparative Study Clinical TrialAdverse outcomes among women presenting with signs and symptoms of ischemia and no obstructive coronary artery disease: findings from the National Heart, Lung, and Blood Institute-sponsored Women's Ischemia Syndrome Evaluation (WISE) angiographic core laboratory.
Women presenting with signs and symptoms of myocardial ischemia frequently have no or nonobstructive coronary artery disease (CAD). ⋯ Among women with signs and symptoms of ischemia, nonobstructive CAD is common and associated with adverse outcomes over the longer term. The new WISE angiographic score appears to be useful for risk prediction in this population.

ReviewRationale and design of the COlchicine for Prevention of the Post-pericardiotomy Syndrome and Post-operative Atrial Fibrillation (COPPS-2 trial): a randomized, placebo-controlled, multicenter study on the use of colchicine for the primary prevention of the postpericardiotomy syndrome, postoperative effusions, and postoperative atrial fibrillation.
The efficacy and safety of colchicine for the primary prevention of the postpericardiotomy syndrome (PPS), postoperative effusions, and postoperative atrial fibrillation (POAF) remain uncertain. Although preliminary data from a single trial of colchicine given for 1 month postoperatively (COPPS trial) were promising, the results have not been confirmed in a large, multicenter trial. Moreover, in the COPPS trial, colchicine was given 3 days postoperatively. ⋯ The COPPS-2 trial will evaluate the use of colchicine for the primary prevention of PPS, postoperative effusions, and POAF, potentially providing stronger evidence to support the use of preoperative colchicine without a loading dose to prevent several postoperative complications. ClinicalTrials.gov Identifier: NCT01552187.

Comparative StudyLong-term clinical outcome after fractional flow reserve- versus angio-guided percutaneous coronary intervention in patients with intermediate stenosis of coronary artery bypass grafts.
Fractional flow reserve (FFR)-guided percutaneous revascularization (percutaneous coronary intervention [PCI]) of intermediate stenosis in native coronary artery is safe and associated with better clinical outcomes as compared with an angiography-guided PCI. It is unknown whether this applies to coronary artery bypass grafts (CABGs). ⋯ An FFR-guided PCI of intermediate stenosis in bypass grafts is safe and results in better clinical outcomes as compared with an angio-guided PCI. This clinical benefit is achieved with a significant overall reduction in procedural costs.
