A pilot randomized controlled trial that evaluated the effect of remote ischemic preconditioning (RIPC) on clinical outcomes following major vascular surgery was performed. Eligible patients were those scheduled to undergo open abdominal aortic aneurysm repair, endovascular aortic aneurysm repair, carotid endarterectomy, and lower limb revascularization procedures. Patients were randomized to RIPC or to control groups. The primary outcome was a composite clinical end point comprising any of cardiovascular death, myocardial infarction, new-onset arrhythmia, cardiac arrest, congestive cardiac failure, cerebrovascular accident, renal failure requiring renal replacement therapy, mesenteric ischemia, and urgent cardiac revascularization. Secondary outcomes were components of the primary outcome and myocardial injury as assessed by serum troponin values. The primary outcome occurred in 19 (19.2%) of 99 controls and 14 (14.1%) of 99 RIPC group patients (P = .446). There were no significant differences in secondary outcomes. Our trial generated data that will guide future trials. Further trials are urgently needed.

GL and ABT successfully aided stent delivery in unfavorable and heavily calcified lesions which otherwise may have been considered unsuitable for PCI.

SummaryWe report a case of a 56-year-old man referred by his family physician with an asymptomatic cardiac murmur.

Dual antiplatelet therapy is well recognized in the prevention of thrombotic complications of acute coronary syndrome and percutaneous coronary interventions. Despite clinical benefits of aspirin and clopidogrel therapy, a number of limitations curtail their efficacy: slow onset of action, variability in platelet inhibitory response and potential drug-drug interactions. Furthermore, the single platelet-activation pathway targeted by these agents allows continued platelet activation via other pathways, ensuring incomplete protection against ischemic events, thus, underscoring the need for alternate antiplatelet treatment strategies. A number of novel antiplatelet agents are currently in advance development and many have established superior effects on platelet inhibition, clinical outcomes and safety profile than clopidogrel in high-risk patients. The aim of this review is to provide an overview of the current status of P2Y12 receptor inhibition and PAR-1 antagonists in determining a future strategy for individualized antiplatelet therapy.
