Filter by:This is a double-blind, multicenter, randomized, placebo-controlled clinical trial. It is planned to enroll patients admitted with anterior ST-segment elevation myocardial infarction (STEMI) within 6h of symptom onset and undergo primary percutaneous coronary intervention (pPCI). Patients who meet the inclusion criteria and without exclusion criteria were randomized 1:1 into the dexmedetomidine (DEX) group or the placebo (saline) group after signing the informed consent. In the DEX group, intravenous injection of DEX was started immediately after enrollment, covering the entire PCI operation, and the administration was stopped at the end of the pPCI. The administration of saline was the same as those in the DEX group. The primary endpoint was the myocardial infarct size (MIS) as assessed by cardiac magnetic resonance imaging (CMR) at 5±2 days post-STEMI. Based on a superiority design and assuming an 20.0% relative infarct size reduction (from 26.0% to 20.8% with a SD of 13.0%), 250 patients are required to be enrolled, accounting for 20% drop-out (α= 0.05 and power= 80%).
The evaluation of the presented study will work on the practicability of inhalative sedation on the ICU, potential benefits and limitations of the ACD system in a postoperative sedated patient population in comparison to a standard intravenous sedation regimen with propofol, and focus on renal and hepatic function, cardioprotection and pharmacoeconomics
Cardiovascular disease is the leading cause of death in the United States. Studies have shown that obesity is an important risk factor for development of cardiovascular disease. Endothelial dysfunction, a pathologic feature of obesity, predicts the occurrence of cardiovascular disease. Recent research findings indicate that consumption of cocoa exerts cardioprotective effects, which include increasing HDL levels, reduction in systolic BP, inhibition of platelet aggregation/activity and activation of endothelial nitric oxide synthase. Proposed is a randomized controlled trial consisting of 4 phases designed to examine the dose-response, and the acute and sustained effects of cocoa consumption on endothelial function as a marker of cardiovascular disease risk in 45 otherwise healthy adults with a BMI 25-35kg/m2.
