Cardiovascular risk and lifetime benefit from preventive treatment in type 2 diabetes: A post hoc analysis of the CAPTURE study

Aim: To assess the potential gain in the number of life-years free of a (recurrent) cardiovascular disease (CVD) event with optimal cardiovascular risk management (CVRM) and initiation of glucose-lowering agents with proven cardiovascular benefit in people with type 2 diabetes (T2D). Materials and Methods: 9,416 individuals with T2D from the CAPTURE study, a non-interventional, cross-sectional, multinational study, were included. The diabetes lifetime-perspective prediction model was used for calculating individual 10-year and lifetime CVD risk. The distribution of preventive medication use was assessed according to predicted CVD risk and stratified for history of CVD. For the estimation of absolute individual benefit from lifelong preventive treatment, including optimal CVRM and the addition of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and sodium-glucose co-transporter-2 inhibitors (SGLT-2is), the model was combined with treatment effects from current evidence. Results: GLP-1 RA or SGLT-2i use did not greatly differ between patients with and without CVD history, while use of blood pressure-lowering medication, statins and aspirin was more frequent in patients with CVD. Mean (standard deviation [SD]) lifetime benefit from optimal CVRM was 3.9 (3.0) and 1.3 (1.9) years in patients with and without established CVD, respectively. Further addition of a GLP-1 RA and an SGLT-2i in patients with CVD gave an added mean (SD) lifetime benefit of 1.2 (0.6) years. Conclusions: Life-years gained free of (recurrent) CVD by optimal CVRM and the addition of a GLP-1 RA or aSGLT-2i is dependent on baseline CVD status. These results aid individualizing prevention and promote shared decision-making in patients with T2D

Antiplatelet Strategies: Evaluating Their Current Role in the Setting of Acute Coronary Syndromes

Numerous clinical trials have established the value of antiplatelet therapies for acute coronary syndromes (ACS). Aspirin (ASA), thienopyridines (i.e., clopidogrel and ticlopidine) and GP IIb/IIIa antagonists comprise the major classes of antiplatelet therapies demonstrated to be of benefit in the treatment of ACS and for the prevention of thrombotic complications of percutaneous coronary intervention (PCI). Clopidogrel is beneficial when administered before and after PCI, and is more effective when combined with either ASA or GP IIb/IIIa inhibitors in preventing post-PCI complications, coronary subacute stent thrombosis, and thrombotic events in general. It is currently unclear whether a higher loading dose of clopidogrel (600 mg) is better than the standard loading dose (300 mg), how long therapy should continue, and which maintenance dose is optimal. The role of the GP IIb/IIIa antagonists in ACS is less clear due to conflicting data from several studies with different patient populations. Currently, it appears that the use of GP IIb/IIIa antagonists might be most beneficial in high-risk ACS patients scheduled to undergo PCI, who demonstrate non-ST-segment elevation myocardial infarction and elevated troponin levels.

A Systematic Review of Gender Differences in Mortality after Coronary Artery Bypass Graft Surgery and Percutaneous Coronary Interventions

Gender differences exist in outcomes, particularly early mortality, for percutaneous interventions (PCI) and coronary artery bypass graft surgery (CABG). Better understanding of this issue may target areas for improvement for all patients undergoing revascularization. Therefore, we summarized the evidence on gender differences in PCI and CABG outcomes, particularly early mortality, and mediators of this difference. Using the key terms “women” or “gender,” “revascularization,” “coronary artery bypass,” “angioplasty,” “stent,” and “coronary intervention,” we searched MEDLINE from 1985 to 2005 for all randomized controlled trials (RCTs) and registries reporting outcomes by gender. Bibliographies and the Web sites of cardiology conferences were also reviewed. The literature was examined to identify gender differences in outcomes and mediators of these differences. We identified 23 studies reporting outcomes by gender for CABG and 48 studies reporting outcomes by gender for PCI. The majority of studies noted greater in-hospital mortality in women than in men, with mortality differences resolving with longer follow-up. Early mortality differences were reduced but not consistently eliminated after adjustment for comorbidities, procedural characteristics, and body habitus. Power to detect gender differences after multivariate adjustment was limited by declining mortality rates and small sample size. Gender was an independent risk factor for complications after both CABG and PCI. Women experience greater complications and early mortality after revascularization. Future exploration is needed of gender differences in quality of care and benefit from combinations of stenting and antiplatelet, and anticoagulant medications in order to optimize treatment.
