[Show abstract][Hide abstract] ABSTRACT: There remains clinical equipoise in the appropriate selection of antiplatelet therapy for the patient on long-term anticoagulation requiring percutaneous coronary intervention. Since most of these patients represent an increasingly aging population, the significant risk of thromboembolism and stent thrombosis must be weighed against the risk of major bleeding. This article reviews the current state of evidence to provide a framework for the practicing clinician.
[Show abstract][Hide abstract] ABSTRACT: Controversy persists regarding the management of patients with cryptogenic stroke and patent foramen ovale (PFO). We performed a meta-analysis of randomized controlled trials comparing PFO closure with medical therapy.
A prospective protocol was developed and registered using the following data sources: PubMed, Cochrane Register of Controlled Trials, conference proceedings, and Internet-based resources of clinical trials. Primary analyses were performed using the intention-to-treat method. Three randomized trials comparing percutaneous PFO closure vs. medical therapy for secondary prevention of embolic neurological events formed the data set. Baseline characteristics were similar. During long-term follow-up, the pooled incidence of the primary endpoint (composite of stroke, death, or fatal stroke) was 3.4% in the PFO closure arm and 4.8% in the medical therapy group [risk-reduction (RR) 0.7 (0.48-1.06); p=0.09]. The incidence of recurrent neurological events (secondary endpoint) was 1.7% for PFO closure and 2.7% for medical therapy [RR 0.66 (0.35-1.24), p=0.19]. There was no difference in terms of death or adverse events between the two groups.
While this meta-analysis of randomized clinical trials demonstrated no statistical significance in comparison to medical therapy, there was a trend towards overall improvement in outcomes in the PFO closure group.

[Show abstract][Hide abstract] ABSTRACT: Controversy persists regarding the optimal revascularization strategy for diabetic patients with multivessel coronary artery disease (MVD). Coronary artery bypass grafting (CABG) has been compared with percutaneous coronary intervention (PCI) using drug-eluting stents (DES) in recent randomized controlled trials (RCTs).
RCTs comparing PCI with DES versus CABG in diabetic patients with MVD who met inclusion criteria were analyzed (protocol registration No. CRD42013003693). Primary end point (major adverse cardiac events) was a composite of death, myocardial infarction, and stroke at a mean follow-up of 4 years. Analyses were performed for each outcome by using risk ratio (RR) by fixed- and random-effects models. Four RCTS with 3052 patients met inclusion criteria (1539 PCI versus 1513 CABG). Incidence of major adverse cardiac events was 22.5% for PCI and 16.8% for CABG (RR 1.34, 95% CI 1.16 to 1.54, P<0.0001). Similar results were obtained for death (14% versus 9.7%, RR 1.51, 95% CI 1.09 to 2.10, P=0.01), and MI (10.3% versus 5.9%, RR 1.44, 95% CI 0.79 to 2.6, P=0.23). Stroke risk was significantly lower with DES (2.3% versus 3.8%, RR 0.59, 95% CI 0.39 to 0.90, P=0.01) and subsequent revascularization was several-fold higher (17.4% versus 8.0%, RR 1.85, 95% CI 1.0 to 3.40, P=0.05).
These data demonstrate that CABG in diabetic patients with MVD at low to intermediate surgical risk (defined as EUROSCORE <5) is superior to MVD PCI with DES. CABG decreased overall death, nonfatal myocardial infarction, and repeat revascularization at the expense of an increase in stroke risk.
