- Acute Coronary Syndromes are the most frequent manifestations of coronary heart disease (CHD). Gender differences in treatment intensity, including differences in level of care, have been reported. Also differences in benefit from certain treatments, especially invasive treatment, have been discussed. Finally, differences in outcome between men and women have been proposed. Results have been inconsistent, partly depending on if and how adjustment for differences in background characteristics has been made.

Red alert for womens heart: the urgent need for more research and knowledge on cardiovascular disease in women

- A recent report of the EuroHeart project has shown that women are still underrepresented in many cardiovascular clinical trials, while important gender differences are present within most areas of heart disease. As the burden of cardiovascular disease is increasing in middle-aged women relative to men, a more profound understanding is needed of the fundamental biological differences that exist between men and women. In the current review, we aim to address the need for more explanatory sex-specific cardiovascular research to be able to adapt existing guidelines for a better heart health in women.

- CONTEXT: Although an invasive strategy is frequently used in patients with non-ST-segment elevation acute coronary syndromes (NSTE ACS), data from some trials suggest that this strategy may not benefit women. OBJECTIVE: To conduct a meta-analysis of randomized trials to compare the effects of an invasive vs conservative strategy in women and men with NSTE ACS. DATA SOURCES: Trials were identified through a computerized literature search of the MEDLINE and Cochrane databases (1970-April 2008) using the search terms invasive strategy, conservative strategy, selective invasive strategy, acute coronary syndromes, non-ST-elevation myocardial infarction, and unstable angina. STUDY SELECTION: Randomized clinical trials comparing an invasive vs conservative treatment strategy in patients with NSTE ACS. DATA EXTRACTION: The principal investigators for each trial provided the sex-specific incidences of death, myocardial infarction (MI), and rehospitalization with ACS through 12 months of follow-up. DATA SYNTHESIS: Data were combined across 8 trials (3075 women and 7075 men). The odds ratio (OR) for the composite of death, MI, or ACS for invasive vs conservative strategy in women was 0.81 (95% confidence interval [CI], 0.65-1.01; 21.1% vs 25.0%) and in men was 0.73 (95% CI, 0.55-0.98; 21.2% vs 26.3%) without significant heterogeneity between sexes (P for interaction = .26). Among biomarker-positive women, an invasive strategy was associated with a 33% lower odds of death, MI, or ACS (OR, 0.67; 95% CI, 0.50-0.88) and a nonsignificant 23% lower odds of death or MI (OR, 0.77; 95% CI, 0.47-1.25). In contrast, an invasive strategy was not associated with a significant reduction in the triple composite end point in biomarker-negative women (OR, 0.94; 95% CI, 0.61-1.44; P for interaction = .36) and was associated with a nonsignificant 35% higher odds of death or MI (OR, 1.35; 95% CI, 0.78-2.35; P for interaction = .08). Among men, the OR for death, MI, or ACS was 0.56 (95% CI, 0.46-0.67) if biomarker-positive and 0.72 (95% CI, 0.51-1.01) if biomarker-negative (P for interaction = .09). CONCLUSIONS: In NSTE ACS, an invasive strategy has a comparable benefit in men and high-risk women for reducing the composite end point of death, MI, or rehospitalization with ACS. In contrast, our data provide evidence supporting the new guideline recommendation for a conservative strategy in low-risk women.

- Background: Intravenous unfractionated heparin (UFH) is recommended in ST-elevation acute myocardial infarction (STEMI), following thrombolysis with fibrin-specific agents. Subcutaneous low-molecular-weight heparins (LMWH), previously proven effective in non-ST-elevation acute coronary syndromes, have been recently investigated in the setting of STEMI. We aimed at evaluating the current level of evidence supporting the use of LMWH in STEMI. Methods: A Medline search of the English language literature between January 1995 and December 2005 was performed and randomized clinical trials comparing LMWH to either placebo or UFH in conjunction with thrombolysis were selected. Results: About 26,800 patients treated with various thrombolytic regimens were included in 12 randomized clinical trials. Dalteparin was superior to placebo on left ventricular thrombosis/arterial thromboembolism, with no significant effect on the early patency rate of the infarct-related artery (IRA). Compared to UFH, dalteparin had no significant effect on clinical events and on the IRA late patency, although less thrombus was present. Enoxaparin was superior to placebo on the medium-term death/reinfarction/angina rate and late IRA patency, and superior also to UFH on in-hospital and medium-term occurrence of death/reinfarction/angina. The effect of enoxaparin on IRA patency rate was not univocal. Compared to placebo, reviparin significantly reduced early and medium-term mortality and reinfarction rates, without a substantial increase in overall stroke rate. As regards safety, bleedings were more frequent than placebo and comparable to UFH in LMWH groups, with the exception of the pre-hospital ASSENT-3 PLUS trial, where in elderly patients, enoxaparin had an incidence of intracranial hemorrhage twice higher than UFH. Conclusions: In-hospital subcutaneous administration of dalteparin, enoxaparin or reviparin, as an adjunct to various thrombolytics in STEMI, appears feasible and at least as effective and safe as intravenous UFH. Before LMWH might be recommended, however, some yet unresolved issues (i.e. use in elderly patients, in severe renal insufficiency, in association with glycoprotein IIb/IIIa inhibitors and during interventional procedures), need to be addressed.
