These models will be suitable for evaluating the antithrombotic effects of every stent, but might be not appropriate for comparing the antithrombotic effects of each oral antithrombotic regimen, since the optimal dosage of antiplatelets and anticoagulants in swine has not been investigated. Inside the present study, the optimal dosage of antiplatelets and anticoagulants was investigated and compared with the control group. While the outcomes differ inside the present study, mostly due to the modest quantity of animals evaluated, there was a tendency for the thrombus volume and bleeding time for you to be inversely proportional, and this result is consistent with every day clinical practice. For that reason, we think the existing preclinical study is among the best methods to compare the antithrombotic effects of every single regimen. Certainly one of the targets for antiplatelets and anticoagulants after stent implantation in individuals with AF is usually to protect against both ST and embolization of an intracardiac thrombus.eight,19 Preceding RCTs have clearly shown that the prevalence of ST is substantially higher inside 30 days following stent implantation. In addition, three aspects have been responsible for greater than 95 of cases of acute (24 h) and subacute (from 24 h to 30 days) ST: the persistence of uncovered struts, malapposition of struts, and underexpansion.20 All three findings highlight that the stent struts have been bare inside the lumen, plus the possibility of thrombus attachment remains till all of the struts are covered by neointimal tissue. Mainly because histological and preclinical studies suggest that most of the struts would remain bare especially inside 30 days of DES implantation,15,21,22 antithrombotic effects in that period play a important roll in preventing ST. The latest substudy with the AUGUSTUS trial demonstrated detailed traits of patients with ST.23 Primary findings of that trial have been that combination therapy with apixaban, a non-vitamin K antagonist OAC (NOACs), along with a P2Y12 inhibitor resulted in considerably fewer bleeding MMP-10 Inhibitor site events with out important affecting the incidence of ischemic events compared with triple therapy after stent implantation in patients with AF.3 These results are constant with these of other RCTs evaluating other NOACs using a comparable regimen.four Within the AUGUSTUS substudy, the incidence of ST was low, but there have been a trend for a relatively higher danger of ST inside the dual therapy group (vitamin K antagonist [VKA] / apixaban + P2Y12 inhibitor) compared with triple therapy group (VKA / apixaban + P2Y12 inhibitor + aspirin).23 Within the AUGUSTUS trial, 92.6 of sufferers received clopidogrel because the P2Y12 inhibitor, and prasugrel was utilized in only 1.two of sufferers.23 The results from the AUGUSTUS trial recommend that the antithrombotic effect of clopidogrel just isn’t adequate, possibly due to CYP2C19 polymorphisms. Conversely, as demonstrated in the present study, the antithrombotic impact was similar among the Prasugrel+OAC and Triple groups, with significantly a considerably shorter bleeding time inside the former; therefore, prasugrel+OAC therapy may very well be a feasible regimen in AF patients who undergo PCI. Study Limitations The present study has some limitations. Initially, the number of the antithrombotic regimens evaluated.
