Background There is great debate on the possible adverse interaction between proton pump inhibitors (PPIs) and clopidogrel. In ad- dition, whether the use of PPIs affects the clinical efficacy of ticagrelor remains less known. We aimed to determine the impact of concomi- tant administration of PPIs and clopidogrel or ticagrelor on clinical outcomes in patients with acute coronary syndrome (ACS) after percuta- neous coronary intervention (PCI). Methods We retrospectively analyzed data fi'om a "real world", international, multi-center registry between 2003 and 2014 (n = 15,401) and assessed the impact of concomitant administration of PPIs and clopidogrel or ticagrelor on 1-year composite primary endpoint (all-cause death, re-infarction, or severe bleeding) in patients with ACS after PCI. Results Of 9429 patients in the final cohort, 54.8% (n = 5165) was prescribed a PPI at discharge. Patients receiving a PPI were older, more often female, and were more likely to have comorbidities. No association was observed between PPI use and the primary endpoint for patients receiving clopidogrel (ad- justed HR: 1.036; 95% CI: 0.903-1.189) or ticagrelor (adjusted HR: 2.320; 95% CI: 0.875-45.151) (Pinteraction = 0.2004). Similarly, use of a PPI was not associated with increased risk of all-cause death, re-infarction, or a decreased risk of severe bleeding for patients treated with either clopidogrel or ticagrelor. Conclusions In patients with ACS following PCI, concomitant use of PPIs was not associated with in- creased risk of adverse outcomes in patients receiving either clopidogrel or ticagrelor. Our findings indicate it is reasonable to use a PPI in combination with clopidogrel or ticagrelor, especially in patients with a higher risk of gastrointestinal bleeding. 展开更多

We performed a meta-analysis of randomized controlled trials(RCTs) to investigate the efficacy and safety of ticagrelor(TIC) vs. clopidogrel(CLO) in patients undergoing percutaneous coronary intervention(PCI). In Jun 2016, a literature search was started and all the studies were conducted from 2010 to 2015. We systematically searched the literature through the MEDLINE database, Cochrane library, and EMBASE database. Quality assessments were evaluated with Jadad quality scale. Data were extracted considering the characteristics of efficacy and safety designs. Six RCTs enrolling 26 244 participants and satisfying the inclusion criteria were finally analyzed. There was a significant decrease of all-cause mortality(MD=0.83, 95%CI=0.74–0.93, P=0.001) and myocardial infarction(MI)(MD=0.78, 95%CI=0.70–0.88, P=0.000). There were no significant differences in stroke(MD=1.34, 95%CI=0.99–1.79, P=0.06), total bleeding(MD=0.97, 95%CI=0.84–1.12, P=0.66), minor or major bleeding(MD=1.06, 95%CI=0.94–1.19, P=0.35) in patients undergoing PCI after treatment with TIC vs. CLO. TIC could be more significant in decreasing all-cause mortality and MI than CLO, but there were no significant differences between TIC and CLO in inhibiting stroke, major bleeding, major or minor bleeding in patients undergoing PCI. 展开更多

Ticagrelor is a potent,direct P2Y12 antagonist with rapid onset of action and intense platelet inhibition,indicated in patients with acute coronary syndromes(ACS).This drug is usually well tolerated,but some patients experience serious adverse effects:Major bleeding;gastrointestinal disturbances;dyspnoea;ventricular pauses > 3 s.Given the unexpected high incidence of bradyarrhythmias,a PLATO substudy monitored this side effect,showing that ticagrelor was associated with an increase in the rate of sinus bradycardia and sinus arrest compared to clopidogrel.This side effect was usually transient,asymptomatic and not associated with higher incidence of severe atrioventricular(AV) block or pacemaker needs.A panel of experts from Food and Drug Administration did not consider bradyarrhythmias a serious problem in clinical practice and,accordingly,current labeling of the drug does not give any precaution or contraindication regarding this issue.However,recently some articles have described ACS patients with high-degree,life-threatening,AV block requiring drug discontinuation and,in some cases,pacemaker implantation.In this paper,we describe and discuss five published case reports of severe AV block following ticagrelor therapy and two other cases managed in our Hospital.The analysis of literature suggests that,although rarely,ticagrelor can be associated with lifethreatening AV block.Caution and careful monitoring are required especially in patients with already compromised conduction system and/or treated with AV blocking agents.Future studies,with long-term rhythm monitoring,would help to define the outcome of patients at higher risk of developing this complication. 展开更多

Background Ticagrelor provides enhanced antiplatelet efficacy but increased risk of bleeding and dyspnea. This study aimed to display the relationship between ADP-induced platelet-fibrin clot strength (MAADP) and clinical outcomes in acute coronary syndrome (ACS) patients treated by ticagrelor. Methods Consecutive Chinese-Han patients with ACS who received maintenance dose ofticagrelor on top of aspirin were recruited. After 5-day ticagrelor maintenance treatment, MAADP measured by thrombelastography (TEG) were recorded for the evaluation of ticagrelor anti-platelet reactivity. Pre-specified cutoffs of MAADP 〉 47 mm for high on-treatment platelet reactivity (HTPR) and MAADP 〈 31 mm for low on-treatment platelet reactivity (LTPR) were applied for evaluation. The occurrences of primary ischemic cardiovascular events (including a composite of cardiac death, non-fatal myocardial infarction and stroke), the Thrombolysis in Myocardial Infarction (TIMI) defined bleeding events, and ticagrelor related dyspnea were recorded after a follow-up of three months. Results Overall, 176 ACS patients (Male: 79.55%, Age: 59.91 ±10.54 years) under ticagrelor maintenance treatment were recruited. The value of MAADP ranged from 4.80% to 72.90% (21.27% ± 12.07% on average), with the distribution higher skewed towards the lower values. Using the pre-specific cutoffs for HTPR and LTPR, seven patients (3.98%) were identified as HTPR and 144 patients (81.82%) as LTPR. After a follow-up of three months in 172 patients, major cardiovascular events occurred in no patient, but TIMI bleeding events in 81 (47.09%) with major bleedings in three patients. All patients with major bleedings were classified as LTPR. Ticagrelor related dyspnea occurred in 31 (18.02%) patients, with 30 (21.28%) classified as LTPR and no one as HTPR (P = 0.02). Conclusions In ticagrelor treated ACS patients, MAADP measured by TEG might be valuable for the prediction of major bleeding and ticagrelor related dyspnea. Due to the small number of patients with HTPR after ticagrelor maintenance treatment, larger scale study should be warranted to verify the relationship between MAADP defined HTPR and ticagrelor related ischemic events. 展开更多

Clopidogrel is a mainstay in the treatment of patients with acute coronary syndromes or those receiving endovascular prostheses.However,its efficacy has been challenged in the recent past by studies suggesting variable individual responsiveness and by new,more potent competitors,such as prasugrel and ticagrelor. But what is the actual body of evidence in support of clopidogrel?Is there any dark side of the moon?What is the role of prasugrel,which has already been approved in Europe and in the United States?And what will be the future role of ticagrelor,when approved for routine clinical practice?We hereby concisely summarize the scope of this clinical choice,providing arguments in favor and against each of the three antiplatelet agents:clopidogrel,prasugrel,and ticagrelor. 展开更多

Objective:There exist conflicting data on the efficacy and safety of ticagrelor and clopidogrel in East Asian patients with acute coronary syndrome(ACS).We performed a meta-analysis to evaluate whether ticagrelor or clopidogrel produces better outcomes for East Asian patients with ACS.Methods:We searched for randomized controlled trials reporting associations between ticagrelor and clopidogrel in East Asian patients with acute coronary syndrome in PubMed,EMBASE,web of science and Cochrane central register of controlled trials.Results:Ten studies involving 3715 participants were qualified for our analysis.The major adverse cardiovascular events(MACE)were significantly decreased in patients with ticagrelor treatment compared to those with clopidogrel(risk ratio[RR]:0.61;95%confidence interval[CI]:0.38-0.98;P=0.042).There was no significant difference in all-cause death(RR:0.89;95%CI:0.61-1.29;P=0.540),cardiovascular death(RR:0.86;95%CI:0.58-1.27;P=0.451),myocardial infarction(RR:0.91;95%CI:0.65-1.27;P=0.575)and stroke(RR:0.77;95%CI:0.44-1.36;P=0.372)between ticagrelor and clopidogrel.Ticagrelor was associated with a significantly higher risk of bleeding compared to clopidogrel(RR:1.71;95%CI:1.37-2.13;P=0.000).Conclusion:The present meta-analysis demonstrates that ticagrelor reduced the incidence of MACE in ACS patients from East Asia compared with clopidogrel.However,it increased the risk of bleeding. 展开更多

Objective:To investigate the effects of different doses of ticagrelor on coronary blood flow, inflammatory response and myocardial enzyme spectrum in patients with acute myocardial infarction.Methods: A total of 180 patients with acute myocardial infarction who were treated in our hospital between December 2015 and March 2017 were reviewed and divided into the routine dose group (n=87) who accepted routine dose of ticagrelor therapy and loading dose group (n=93) who accepted loading dose of ticagrelor therapy. The differences in coronary blood flow, inflammatory response and myocardial enzyme spectrum were compared between the two groups before and after treatment.Results: Immediately after admission, there was no statistically significant difference in the coronary blood flow levels, inflammatory response and myocardial enzyme spectrum contents between the two groups. At 24 h after percutaneous coronary intervention (PCI), the coronary blood flow parameters SPV, DPV and CFVR levels in loading dose group were higher than those in routine dose group;serum inflammatory factors PCT, IL-6 and CRP contents were lower than those of routine dosage group;myocardial enzyme spectrum indexes cTnⅠ, LDH, HBDH and MB contents were lower than those of routine dose group.Conclusion: Loading dose of ticagrelor therapy before PCI can effectively optimize the coronary blood flow after PCI, reduce the systemic inflammatory response and protect the myocardial function in patients with acute myocardial infarction. 展开更多

Objective: To compare the effect of ticagrelor and clopidogrel on serum inflammatory factor level in antiplatelet therapy for acute myocardial infarction (AMI) patients after percutaneous coronary intervention (PCI). Methods: 113 cases of AMI underwent PCI in our hospital from March 2016 to February 2018 were selected and divided into two groups. The experimental group (n=58) received the ticagrelor, while the control group (n=55) received the clopidogrel. Then the platelet aggregation, serum inflammatory factors, liver and kidney function, and cardiovascular and cerebrovascular events at the post 6-mon follow-up were compared between groups. Results: The platelet aggregation rate had no difference between the two groups before PCI (P>0.05), which were higher in the control group than in the experimental group at the post-PCI 24 h and 7 d (P<0.05). The levels of C-reactive protein (CRP), interleukin-6 (IL-6), and interleukin-8 (IL-8) had no difference between the two groups before PCI (P>0.05), which were higher in the control group than in the experimental group at the post-PCI 24 h and 7 d (P<0.05). The preoperative glutamic pyruvic transaminase (ALT) had no difference with that at the post-PCI 24 h and 7 d in both groups (P>0.05). The serum creatinine (Scr) levels had no difference between the two groups before PCI (P>0.05), which were lower in the control group than in the experimental group at the post-PCI 24 h and 7 d (P<0.05). The incidence rate of the cardiovascular and cerebrovascular events at the post 6-months follow-up of the control group was higher than that of the experimental group (14.55% (8/55) vs 5.17% (3/58), P<0.05)Conclusion: Compared with the clopidogrel treatment, the application of ticagrelor has a better effect in antiplatelet therapy for AMI patients underwent PCI, which can effectively control serum inflammatory factor levels, stabilize liver function, reduce the occurrence of cardiovascular and cerebrovascular events, and improve the prognosis. 展开更多

Objective: To explore the effects of Ticagrelor on oxidative stress, coagulation function, platelet function and related factors in patients with coronary artery disease undergoing interventional therapy. Methods: A total of 140 patients with coronary artery disease who underwent percutaneous coronary intervention in our hospital from October 2016 to March 2018 were selected as the study subjects and were divided into control group (70 cases) and observation group (70 cases) by drawing lots. Both groups were treated with symptomatic routine therapy before operation. On this basis, the control group was treated with clopidogrel before operation, and the observation group was treated with Ticagrelor before operation on the basis of routine treatment. The changes of oxidative stress, coagulation index, platelet function and related factors were compared between the two groups before and after treatment. Results: Before treatment, there were no significant differences in oxidative stress factors, coagulation parameters, platelet parameters and related factors factors between the two groups. After treatment, the levels of MDA, MPAR, VEGF and MMP-9 in the two groups were lower than those before treatment, while the levels of SOD, APTT, TT and PT were higher than those before treatment;and the levels of MDA, MPAR, VEGF, MMP-9, APTT and PT in the observation group were significantly lower than those in the control group after treatment, while the levels fo SOD, TT and IPA in the observation group were significantly higher than those in the control group. Conclusions: Ticagrelor can better reduce oxidative stress injury, improve coagulation function and coronary stenosis, and inhibit platelet aggregation in patients with coronary heart disease undergoing PCI than clopidogrel. It has clinical popularization significance. 展开更多
