Review Meta Analysis
Long-term effects of weight-reducing interventions in hypertensive patients: systematic review and meta-analysis.
Weight loss is recommended in all major guidelines for antihypertensive therapy. We searched for randomized controlled trials investigating the effects of weight-reducing diets, pharmacologic substances, and invasive interventions for weight reduction on patient-relevant end points and blood pressure (BP) in patients with essential hypertension. No information on the effects on patient-relevant end points was available. ⋯ Systolic BP increased with sibutramine treatment (WMD, 3.2 mm Hg). In patients with essential hypertension, therapy with a weight loss diet or orlistat resulted in reductions in body weight and BP. Although sibutramine treatment reduced body weight, it did not lower BP.

Despite its limitations, unfractionated heparin (UFH) is the recommended anticoagulant during percutaneous coronary intervention (PCI). Few randomized trials have compared low-molecular-weight heparin (LMWH) and UFH, and most lacked the power to detect a difference between the 2 anticoagulants in terms of safety or efficacy. Our objective was to perform a meta-analysis of randomized trials comparing the efficacy and safety of LMWH vs UFH as anticoagulants in the setting of PCI. ⋯ The use of intravenous LMWH during PCI is associated with a significant reduction in major bleeding events compared with UFH, without compromising outcomes on hard ischemic end points.

Optimal diagnosis and timely treatment of patients with an acute coronary syndrome (ACS) depends on distinguishing differences between popular "myths" about ischemic symptoms in women and men. Chest pain or discomfort is regarded as the hallmark symptom of ACS, and its absence is regarded as "atypical" presentation. This review describes the presenting symptoms of ACS in women compared with men and ascertains whether women should have a symptom message that is separate or different from that for men. ⋯ Women are significantly less likely to report chest pain or discomfort compared with men. These differences, however, are not likely large enough to warrant sex-specific public health messages regarding the symptoms of ACS at the present time. Further research must systematically investigate sex differences in the clinical presentation of ACS symptoms and must include standardized data collection efforts.
