In recent years, bariatric surgery has become an increasingly used therapeutic option for morbid obesity. The effect of weight loss after bariatric surgery on the predicted risk of coronary heart disease (CHD) has not previously been studied. We evaluated baseline (preoperative) and follow-up (postoperative) body mass index, CHD risk factors, and Framingham risk scores (FRSs) for 109 consecutive patients with morbid obesity who lost weight after laparoscopic Roux-en-Y gastric bypass surgery. ⋯ In conclusion, weight loss results in a significant decrease in FRS 10-year predicted CHD risk. Bariatric surgery decreases CHD risk to rates lower than the age- and gender-adjusted estimates for the general population. These data suggest substantial and sustained weight loss after bariatric surgery may be a powerful intervention to decrease future rates of myocardial infarction and death in the morbidly obese.

Meta Analysis
Risk of cardiovascular events in patients receiving celecoxib: a meta-analysis of randomized clinical trials.
Some nonsteroidal anti-inflammatory drugs (NSAIDs), including cyclooxygenase-2 selective inhibitors, have been associated with increased cardiovascular (CV) events in recent clinical trials or observational studies. To determine whether the cyclooxygenase-2 selective inhibitor celecoxib affects CV risk, the incidence of CV events was analyzed in patients treated with celecoxib, placebo, or nonselective NSAIDs in the clinical trial database for celecoxib using defined Antiplatelet Trialists' Collaboration end points of nonfatal myocardial infarction, nonfatal stroke, and CV death. Patient data were derived from studies in osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, low back pain, and Alzheimer's disease. ⋯ Event rates were similar for adjudicated and nonadjudicated data. Dose of celecoxib, the use of aspirin, or the presence of CV risk factors did not alter these results. In conclusion, these analyses failed to demonstrate an increased CV risk with celecoxib relative to placebo and demonstrated a comparable rate of CV events with celecoxib treatment compared with nonselective NSAIDs.

Multicenter Study
Possible gender-related differences in the risk-to-benefit ratio of thrombolysis for acute submassive pulmonary embolism.
The indications for thrombolytic treatment in normotensive patients with pulmonary embolism (PE) are still the subject of debate, and it also remains questionable whether the efficacy and safety of thrombolysis are similar in men and women. To address the latter issue, the present study analyzed a large population of 428 women and 291 men with acute submassive PE derived from a prospective multicenter registry. Initial treatment consisted either of thrombolysis (<24 hours after diagnosis) or heparin alone. ⋯ Gender-specific differences were also observed with regard to the reduction of symptomatic PE recurrence (in men, from 21.6% to 8.2%, p = 0.009; in women, from 16.9% to 8.3%, p = 0.049). In contrast, thrombolysis resulted in a more than threefold increase in major bleeding in women (from 8.4% to 27.1%, p <0.001), a more pronounced effect than in men (from 6.9% to 15.1%, p = 0.055). In conclusion, the present study generated the hypothesis that women with submassive PE might benefit less from thrombolytic treatment in terms of survival and PE recurrence and that they could be exposed to a higher bleeding risk compared with men.

The Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes with Early Implementation of the American College of Cardiology/American Heart Association Guidelines (CRUSADE) initiative is a prospective, rapid-cycle quality-improvement initiative that focuses on improving both the diagnostic evaluation of patients with non-ST-segment elevation (NSTE) acute coronary syndromes (ACS; defined as ischemic ST-segment changes and/or positive cardiac markers) and the use of treatments recommended by the American College of Cardiology (ACC)/American Heart Association (AHA) guidelines for management of NSTE ACS. The ultimate goal of the CRUSADE initiative is to improve the quality of care among high-risk patients with NSTE ACS. ⋯ Cumulatively, the CRUSADE initiative has collected data from >165,000 patients with NSTE ACS admitted at >400 US hospitals since 2001. This article reviews the major results from the CRUSADE initiative on risk stratification, gaps in guidelines adherence, paradoxical care, and the association of guideline adherence with outcomes.
