Bivalirudin versus heparin in patients planned for coronary stenting

(Brigham and Women's Hospital) Researchers from Brigham and Women's Hospital conducted an analysis of all of the previous trials to date to better define both the benefits and risks of the competing anticoagulants. They found that, compared with heparin-based regimens, bivalirudin-based regimens increased the risk of heart attack and stent thrombosis. Bivalirudin-based regimens decreased the risk of bleeding, but by how much depended on whether other blood thinners were used more with heparin than with bivalirudin.

AbstractAlthough potent P2Y12 inhibitor-based dual antiplatelet therapy (DAPT) has replaced clopidogrel-based therapy as the standard treatment in patients with acute myocardial infarction (AMI), there is a concern about the risk of bleeding in East Asian patients. We compared the efficacy and safety of cilostazol-based triple antiplatelet therapy (TAT) with potent P2Y12 inhibitor-based DAPT in Korean patients. A total of 4152 AMI patients who underwent percutaneous coronary intervention (PCI) in the Korea Acute Myocardial Infarction Registry were analyzed retrospectively. Patients were divided into two groups: the TAT gro...

RARITAN, NJ, March 28, 2020 – The Janssen Pharmaceutical Companies of Johnson &Johnson today announced the VOYAGER PAD study met its primary efficacy and principal safety endpoints, demonstrating the XARELTO® (rivaroxaban) vascular dose (2.5 mg twice daily) plus aspirin (100 mg once daily) was superior to aspirin alone in reducing the risk of major adverse limb and cardiovascular (CV) events by 15 percent in patients with symptomatic peripheral artery disease (PAD) after lower-extremity revascularization, with similar rates of TIMI[1] major bleeding. VOYAGER PAD is the only study to show a significant benefit...

nd Investigators Abstract Background: Patients with established coronary artery disease (CAD) or peripheral artery disease (PAD) often have diabetes mellitus. These patients are at high risk of future vascular events. Methods: In a prespecified analysis of the COMPASS trial, we compared the effects of rivaroxaban (2.5 mg twice daily) plus aspirin (100 mg daily) versus placebo plus aspirin in patients with diabetes versus without diabetes in preventing major vascular events. The primary efficacy endpoint was the composite of cardiovascular death, myocardial infarction (MI), or stroke. Secondary endpoints included a...

This study, performed from January 1, 2004, to November 31, 2014, at 55 centers in Korea, was based on the Grand Drug-Eluting Stent registry, which is a Korean, nationwide, multicenter, pooled registry of drug-eluting stents. The registry enrolled all-comers without any exclusion criteria except patient withdrawal of consent. A total of 1329 patients with AMI who had an overt intracoronary thrombus at the initial coronary angiography were analyzed. The efficacy end point was a 1-year major adverse cardiovascular event, defined as a composite of all death, myocardial infarction, target lesion revascularization, and stent th...

The objective of this post hoc analysis was to analyze real-world dual antiplatelet therapy (DAPT) regimens following polymer-free sirolimus-eluting stent (PF-SES) implantations in an unselected patient population.MethodsPatient-level data from two all-comers observational studies (ClinicalTrials.gov Identifiers: NCT02629575 and NCT02905214) were pooled and analyzed in terms of their primary endpoint. During the data verification process, we observed substantial deviations from DAPT guideline recommendations. To illuminate this gap between clinical practice and guideline recommendations, we conducted a post hoc analysis of...

Conclusion: In adults with AF after PCI, dual therapy reduces risk for bleeding compared with triple therapy, whereas its effects on risks for death and ischemic end points are still unclear. Primary Funding Source: None. PMID: 32176890 [PubMed - as supplied by publisher]

AbstractPatients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) have traditionally received triple antithrombotic therapy (TAT) consisting of aspirin and a P2Y12 inhibitor plus an oral anticoagulant (OAC) to reduce atherothrombotic events, even though this strategy is associated with a high risk of severe bleeding. Recent trials have indicated that dual antithrombotic therapy (DAT), consisting of a P2Y12 inhibitor plus an OAC, may be superior to TAT in terms of bleeding risk; however, the  trade-off regarding ischemic complications may be questionable. Patients who have had a myocard...

AbstractGuidelines advice against dual antiplatelet therapy (DAPT) discontinuation less than 12  months after percutaneous coronary intervention with drug-eluting stents (DES-PCI). However, any delay of necessary surgery in patients with descending thoracic (DTA) or abdominal aortic aneurysm (AAA), treated by DES-PCI, increases the risk of aneurysm rupture/dissection. We evaluated the safety of 8-week waiting time between DES-PCI and endovascular aortic repair (EVAR). 1152 consecutive patients with coronary artery disease (CAD) needing elective DTA or AAA repair were enrolled and divided into two groups. Group A inclu...

CONCLUSIONS: CM in vitro is procoagulant and prothrombotic. CM in vivo can augment myocardial damage and can be prohemostatic in the presence of bleeding. CM's procoagulant and antifibrinolytic activities likely involve, at least in part, its ability to bind factor Xa and enhance thrombin generation. Future work is needed to clarify CM's pathophysiology and its mechanistic influences on hemostasis or thrombosis. PMID: 32102568 [PubMed - as supplied by publisher]
