The optimal antithrombotic strategy for patients with a long-term indication for anticoagulation and acute coronary syndrome (ACS) or percutaneous coronary intervention (PCI) remains controversial. This meta-analysis aims to compare randomised trials' outcomes of these patients, focussing on dual versus triple antithrombotic and non vitamin K oral anticoagulants (NOACs) versus vitamin K oral anticoagulants regimens.. Medline, Embase and Cochrane databases were searched from January 1980 to March 2019 yielding 309 articles, and after careful screening, five randomized trials totalling 10 643 patients were included for analysis.. Dual antithrombotic regimens were associated with significantly less thrombolysis in myocardial infarction (TIMI) major and minor bleeding [odds ratio (OR) 0.53, 95% confidence interval (CI) 0.40-0.71], with no significant difference in major adverse cardiovascular events (OR 0.93, 95% CI 0.72-1.22) or all-cause mortality (OR 0.89, 95% CI 0.61-1.19). NOAC regimens had significantly lower TIMI major and minor bleeding (OR 0.58, 95% CI 0.43-0.78) and intracranial bleeding (OR 0.33, 95% CI 0.16-0.66), with similar rates of major adverse cardiovascular events (OR 1.00, 95% CI 0.86-1.16) and all-cause mortality (OR 1.01, 95% CI 0.81-1.26).. Dual antithrombotic and NOAC regimens have reduced bleeding without compromising the risk of cardiovascular events or mortality, and should be preferred for patients with ACS or PCI also needing long-term anticoagulation.

Antiplatelet and anticoagulant drugs are the mainstay of treatment of acute coronary syndrome (ACS). The last 30 years have seen the development of various agents, a deeper understanding of the pathobiology of this disease, and an evolution in its treatment. We review the role of contemporary agents in ACS and highlight key clinical trials of these agents.

Platelet inhibitors and anticoagulants are called antithrombotic drugs. New platelet inhibitors prasugrel and ticagrelor are more effective than the traditional clopidogrel, but their use is also accompanied by more frequent bleeding complications. Varfarin has gained true competitors; new oral anticoagulants include dabigatran, rivaroxaban and apixaban. New anticoagulants are easier to use but clearly more expensive. The use of new anticoagulants is also accompanied by several potential problems that the clinician should be aware of.

Dual antiplatelet therapy (DAPT) remains the cornerstone management for the prevention of acute stent thrombosis after percutaneous intervention (PCI). Situations mandating early interruption of DAPT carry a high risk of ischemic complications. Perioperative bridge therapy using Cangrelor, an intravenous P2Y2 inhibitor, may offer a potential solution. Unfortunately, evidence for its use in non-cardiac procedures is limited.. Our protocol demonstrates successful off-label use of IV Cangrelor bridge therapy in a non-cardiac surgery patient. We describe a case of a 77-year old male; triple therapy with Aspirin, Apixaban, and Ticagrelor for recent drug-eluting stent placement required immediate surgical resection of stage I colonic adenocarcinoma.. Cangrelor bridge therapy was utilized both preoperatively and postoperatively without ischemic or bleeding complications. The patient tolerated exploratory laparoscopic colectomy with minimal bleeding and good post-op recovery.. Minimizing the interruption of DAPT therapy in high-risk patients is achievable. However, careful planning with a team-based approach involving surgeons, cardiologists and pharmacists, along with close clinical follow-up and vigilant management of anti-platelet therapy is recommended.
