Long-term and short-term duration of thienopyridine therapy after coronary stenting in patients with chronic kidney disease a meta-analysis of literature studies.
The study aimed to compare the efficacy and safety outcome associated with a short and a prolonged duration of thienopyridine therapy in patients with chronic kidney disease (CKD) after coronary stenting. We systematically searched PubMed, EMBASE and the Cochrane Library from their inception to 1 January 2019 for studies comparing short and prolonged thienopyridine therapy in patients with CKD. Ischemic and bleeding events were considered as the clinical endpoints in this analysis. Odds Ratios (OR) with 95% confidence intervals (CIs) were used as estimates of effect size in random-effect models. Seven studies comprising a total of 17,628 CKD patients were included in the evaluation. Prolonged duration of thienopyridine use, when compared to short-term thienopyridine, was associated with reduced risk of all-cause mortality (odds ratio 0.75, 95% confidence interval: 0.70-0.81, Topics: Aged; Coronary Artery Disease; Female; Hemorrhage; Humans; Male; Middle Aged; Myocardial Infarction; Odds Ratio; Percutaneous Coronary Intervention; Pyridines; Renal Insufficiency, Chronic; Risk Assessment; Stents; Stroke; Time Factors | 2020 |
Preoperative thienopyridine use and outcomes after surgery: a systematic review.
Although studies have demonstrated excess risk of ischemic events if aspirin is withheld preoperatively, it is unclear whether preoperative thienopyridine use influences postoperative outcomes.. We conducted a systematic review of 37 studies (31 cardiac and 6 noncardiac surgery, 3 randomized, 34 observational) comparing postoperative outcomes in patients who were versus were not exposed to thienopyridine in the 5 days before surgery.. Exposure to thienopyridine in the 5 days preceding surgery (compared with no exposure) was not associated with any reduction in postoperative myocardial infarction (23 studies, 12,872 patients, 3.4% vs 3.0%, odds ratio [OR] 0.98; 95% confidence interval [CI], 0.72-1.34), but was associated with increased risks of stroke (16 studies, 10,265 patients, 1.9% vs 1.4%, OR 1.54; 95% CI, 1.08-2.20), reoperation for bleeding (32 studies, 19,423 patients, 4.3% vs 1.8%, OR 2.62; 95% CI, 1.96-3.49), and all-cause mortality (28 studies, 22,990 patients, 3.7% vs 2.6%, OR 1.38; 95% CI, 1.13-1.69). Results were identical when analyses were restricted to long-term users of thienopyridines who continued versus held the medication in the 5 days before surgery. Although all associations were similar in direction for the subset of patients undergoing noncardiac surgery, 97% of the outcome data in this meta-analysis came from cardiac surgery trials.. These data support withholding thienopyridines 5 days before cardiac surgery; there was insufficient evidence to make definitive recommendations for elective noncardiac surgery although the direction and magnitude of associations were similar.

[Thienopyridines in the treatment and prevention of cardiovascular diseases. Part V. Combination of clopidogrel and acetylsalicylic acid in the treatment of stable patients with atherothrombotic cardiovascular diseases].
In a series of articles the authors consider clinical pharmacology and experience of clinical application of blockers of platelet P2Y12 receptors, most well known representatives of which ticlopidine and clopidogrel according to chemical structure belong to thienopyridine derivatives. In the fifth communication we consider data of two randomized studies in which efficacy and safety of clopidogrel in combination with acetylsalicylic acid (ASA) has been assessed in comparison with ASA in stable patients with atherothrombotic cardiovascular disease. It has been shown in both studies that in stable patients with atherothrombotic cardiovascular disease long-term therapy with combination of clopidogrel and ASA was no more effective than monotherapy with ASA or clopidogrel but was associated with high risk of hemorrhagic complications. Thus contrary to acute coronary syndromes and percutaneous interventions with stenting combinations of clopidogrel and ASA is not indicated to patients with stable course cardiovascular diseases.

Role of antiplatelet drugs in the prevention of cardiovascular events.
Antiplatelet drugs have an established place in the prevention of vascular events in a variety of clinical conditions, such as myocardial infarction, stroke and cardiovascular death. Both European and American guidelines recommend the use of antiplatelet drugs in patients with established coronary heart disease and other atherosclerotic disease. In high-risk patients, such as those with post-acute myocardial infarction (AMI), ischaemic stroke or transient ischaemic attack, and in patients with stable or unstable angina, peripheral arterial occlusive disease or atrial fibrillation, antiplatelet treatment may reduce the risk of a serious cardiovascular event by approximately 25%, including reduction of non-fatal myocardial infarction by 1/6, non-fatal stroke by 1/4 and cardiovascular death by 1/6. Some data indicate that antiplatelet drugs may also have a role in primary prevention. In people who are aged over 65 years, or have hypertension, hypercholesterolaemia, diabetes, obesity or familial history of myocardial infarction at young age, aspirin may reduce both cardiovascular deaths and total cardiovascular events. Aspirin has been studied and used most extensively. It may exert its beneficial effect not only by acting on platelets, but also by other mechanisms, such as preventing thromboxane A2 (TXA2)-induced vasoconstriction or reducing inflammation. Indeed, experimental data show that low-dose aspirin may suppress vascular inflammation and thereby increase the stability of atherosclerotic plaque. Moreover, in human studies, aspirin seems to be most effective in those with elevated C-reactive protein levels. Vascular events, however, do occur despite aspirin administration. This may be due to platelet activation by pathways not blocked by aspirin, intake of drugs that interfere with aspirin effect or aspirin resistance. In the CAPRIE (Clopidogrel vs. Aspirin in Patients at Risk of Ischaemic Events) study, long-term clopidogrel administered to patients with atherosclerotic vascular disease was more effective than aspirin in reducing the combined risk of ischaemic stroke, myocardial infarction or vascular death. In the setting of coronary stenting, a double regimen including aspirin and ticlopidine or clopidogrel has proved more effective in the prevention of in-stent thrombosis than aspirin alone. Chronic oral administration of the inhibitors of platelet membrane receptor GP IIb/IIIa has been largely disappointing.

Efficacy and Safety of Vorapaxar With and Without a Thienopyridine for Secondary Prevention in Patients With Previous Myocardial Infarction and No History of Stroke or Transient Ischemic Attack: Results from TRA 2°P-TIMI 50.
Vorapaxar antagonizes protease-activated receptor 1, the primary receptor for thrombin on human platelets, and reduces recurrent thrombotic events in stable patients with a previous myocardial infarction (MI). We wished to determine whether the efficacy and safety of antiplatelet therapy with vorapaxar was modified by concurrent thienopyridine use.. The Thrombin Receptor Antagonist in Secondary Prevention of Atherothrombotic Ischemic Events-Thrombolysis in Myocardial Infarction 50 (TRA 2°P-TIMI 50) was a randomized, double-blind, placebo-controlled trial of vorapaxar in 26,449 patients with previous atherothrombosis. This prespecified analysis included 16,897 patients who qualified with a MI in the preceding 2 weeks to 12 months and was restricted to patients without a history of stroke or transient ischemic attack given its contraindication in that population. Randomization was stratified on the basis of planned thienopyridine use. Thienopyridine was planned at randomization in 12,410 (73%). Vorapaxar significantly reduced the composite of cardiovascular death, MI, and stroke in comparison with placebo regardless of planned thienopyridine therapy (planned thienopyridine, hazard ratio, 0.80, 0.70-0.91, P<0.001; no planned thienopyridine, hazard ratio, 0.75; 0.60-0.94, P=0.011; P-interaction=0.67). Findings were similar when patients were stratified by actual thienopyridine use at baseline (P-interaction=0.82) and through 18 months (P-interaction=0.44). Global Use of Strategies to Open Occluded Coronary Arteries (GUSTO) moderate or severe bleeding risk was increased with vorapaxar and was not significantly altered by planned thienopyridine (planned, hazard ratio, 1.50; 1.18-1.89, P<0.001; no planned, hazard ratio, 1.90, 1.17-3.07, P=0.009; P-interaction=0.37) or actual thienopyridine use (P-interaction=0.24).. Vorapaxar reduced cardiovascular death, MI, or stroke in stable patients with a history of previous MI, whether treated concomitantly with a thienopyridine or not. The relative risk of moderate or severe bleeding was similarly increased irrespective of thienopyridine use.. URL: http://www.clinicaltrials.gov. Unique identifier: NCT00526474.

Ischaemic cardiac outcomes in patients with atrial fibrillation treated with vitamin K antagonism or factor Xa inhibition: results from the ROCKET AF trial.
We investigated the prevalence of prior myocardial infarction (MI) and incidence of ischaemic cardiovascular (CV) events among atrial fibrillation (AF) patients.. In ROCKET AF, 14 264 patients with nonvalvular AF were randomized to rivaroxaban or warfarin. The key efficacy outcome for these analyses was CV death, MI, and unstable angina (UA). This pre-specified analysis was performed on patients while on treatment. Rates are per 100 patient-years. Overall, 2468 (17%) patients had prior MI at enrollment. Compared with patients without prior MI, these patients were more likely to be male (75 vs. 57%), on aspirin at baseline (47 vs. 34%), have prior congestive heart failure (78 vs. 59%), diabetes (47 vs. 39%), hypertension (94 vs. 90%), higher mean CHADS2 score (3.64 vs. 3.43), and fewer prior strokes or transient ischaemic attacks (46 vs. 54%). CV death, MI, or UA rates tended to be lower in patients assigned rivaroxaban compared with warfarin [2.70 vs. 3.15; hazard ratio (HR) 0.86, 95% confidence interval (CI) 0.73-1.00; P = 0.0509]. CV death, MI, or UA rates were higher in those with prior MI compared with no prior MI (6.68 vs. 2.19; HR 3.04, 95% CI 2.59-3.56) with consistent results for CV death, MI, or UA for rivaroxaban compared with warfarin in prior MI compared with no prior MI (P interaction = 0.10).. Prior MI was common and associated with substantial risk for subsequent cardiac events. Patients with prior MI assigned rivaroxaban compared with warfarin had a non-significant 14% reduction of ischaemic cardiac events.

Patterns of long-term thienopyridine therapy and outcomes in patients with acute coronary syndrome treated with coronary stenting: Observations from the TIMI-38 Coronary Stent Registry.
The optimal duration of dual antiplatelet therapy (DAPT) after acute coronary syndrome (ACS) is not known. Factors influencing DAPT duration are not well described.. We hypothesized that continued DAPT 12 months beyond ACS would be associated with patient factors such as stent type and that it may be associated with lower rates of ischemic events.. The TIMI 38 Coronary Stent Registry (CSR) followed patients who completed the TRITON-TIMI 38 trial, received a stent, and were alive and event free. Continuation of DAPT was determined by the treating physician.. The CSR enrolled 2110 patients (1679>12 months from index ACS) and followed for a median of 2.1 additional years. DAPT was continued in 554 (26%) and was more likely to be continued in patients with drug-eluting stents (DES; 54%) and in North America. The rate of cardiovascular death, MI, or stroke was 2.35% per year, and 13 patients (0.6%) experienced Academic Research Consortium definite or probable ST. Recurrent ischemic events were similar between patients who continued thienopyridine therapy and those who stopped at registry entry (P = 0.74 for cardiovascular death/MI/stroke; P = 0.72 for definite or probable ST). After propensity score adjustment, there was no significant difference in cardiovascular death/MI/stroke (P = 0.55) or bleeding (P = 0.51) with prolonged DAPT.. Patients stabilized for a year after ACS and stenting have low rates of ST relative to overall cardiovascular events. The decision to continue DAPT maybe associated with stent type (DES vs bare-metal stent) and region.

Rivaroxaban versus placebo in patients with acute coronary syndromes (ATLAS ACS-TIMI 46): a randomised, double-blind, phase II trial.
Rivaroxaban is an oral direct factor Xa inhibitor that has been effective in prevention of venous thromboembolism in patients undergoing elective orthopaedic surgery. However, its use after acute coronary syndromes has not been investigated. In this setting, we assessed the safety and efficacy of rivaroxaban and aimed to select the most favourable dose and dosing regimen.. In this double-blind, dose-escalation, phase II study, undertaken at 297 sites in 27 countries, 3491 patients stabilised after an acute coronary syndrome were stratified on the basis of investigator decision to use aspirin only (stratum 1, n=761) or aspirin plus a thienopyridine (stratum 2, n=2730). Participants were randomised within each strata and dose tier with a block randomisation method at 1:1:1 to receive either placebo or rivaroxaban (at doses 5-20 mg) given once daily or the same total daily dose given twice daily. The primary safety endpoint was clinically significant bleeding (TIMI major, TIMI minor, or requiring medical attention); the primary efficacy endpoint was death, myocardial infarction, stroke, or severe recurrent ischaemia requiring revascularisation during 6 months. Safety analyses included all participants who received at least one dose of study drug; efficacy analyses were by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00402597.. Three patients in stratum 1 and 26 in stratum 2 never received the study drug. The risk of clinically significant bleeding with rivaroxaban versus placebo increased in a dose-dependent manner (hazard ratios [HRs] 2.21 [95% CI 1.25-3.91] for 5 mg, 3.35 [2.31-4.87] for 10 mg, 3.60 [2.32-5.58] for 15 mg, and 5.06 [3.45-7.42] for 20 mg doses; p<0.0001). Rates of the primary efficacy endpoint were 5.6% (126/2331) for rivaroxaban versus 7.0% (79/1160) for placebo (HR 0.79 [0.60-1.05], p=0.10). Rivaroxaban reduced the main secondary efficacy endpoint of death, myocardial infarction, or stroke compared with placebo (87/2331 [3.9%] vs 62/1160 [5.5%]; HR 0.69, [95% CI 0.50-0.96], p=0.0270). The most common adverse event in both groups was chest pain (248/2309 [10.7%] vs 118/1153 [10.2%]).. The use of an oral factor Xa inhibitor in patients stabilised after an acute coronary syndrome increases bleeding in a dose-dependent manner and might reduce major ischaemic outcomes. On the basis of these observations, a phase III study of low-dose rivaroxaban as adjunctive therapy in these patients is underway..

Outcome in elderly patients undergoing primary coronary intervention for acute myocardial infarction: results from the Controlled Abciximab and Device Investigation to Lower Late Angioplasty Complications (CADILLAC) trial.
Biological age is a strong determinant of prognosis in patients with acute myocardial infarction (AMI). We sought to examine the impact of age after primary percutaneous coronary intervention in AMI and to determine whether routine coronary stent implantation and/or platelet glycoprotein IIb/IIIa inhibitors improve clinical outcomes in elderly patients after primary angioplasty.. In the CADILLAC trial, 2082 patients with AMI were randomized to balloon angioplasty, angioplasty plus abciximab, stenting alone, or stenting plus abciximab. No patient was excluded on the basis of advanced age; patients ranging from 21 to 95 years of age were enrolled. One-year mortality increased for each decile of age, exponentially after 65 years of age (1.6% for patients <55 years, 2.1% for 55 to 65 years, 7.1% for 65 to 75 years, 11.1% for patients >75 years; P<0.0001). Elderly patients also had increased rates of stroke and major bleeding compared with their younger counterparts. Among elderly patients (> or =65 years), 1-year rates of ischemic target revascularization (7.0% versus 17.6%; P<0.0001) and subacute or late thrombosis (0% versus 2.2%; P=0.005) were reduced with stenting compared with balloon angioplasty. Routine abciximab administration, although safe, was not of definite benefit in elderly patients. Rates of mortality, reinfarction, disabling stroke, and major bleeding in the elderly were independent of reperfusion modality.. Despite contemporary mechanical reperfusion strategies, mortality, major bleeding, and stroke rates remain high in elderly patients undergoing primary percutaneous coronary intervention, outcomes that are not affected by stents or glycoprotein IIb/IIIa inhibitors. By reducing restenosis, however, stent implantation improves clinical outcomes in elderly patients with AMI.

Mortality Following Cardiovascular and Bleeding Events Occurring Beyond 1 Year After Coronary Stenting: A Secondary Analysis of the Dual Antiplatelet Therapy (DAPT) Study.
Early cardiovascular and bleeding events after coronary stenting are associated with high risk of morbidity and mortality.. To assess the prognosis of cardiovascular and bleeding events occurring beyond 1 year after coronary stenting.. This secondary analysis is derived from data from the Dual Antiplatelet Therapy (DAPT) Study, a multicenter trial involving 220 US and international clinical sites from 11 countries. The study dates were August 2009 to May 2014. Individuals who underwent coronary stenting and completed 12 months of thienopyridine plus aspirin therapy without ischemic or bleeding events remained on an aspirin regimen and were randomized to continued thienopyridine therapy vs placebo for 18 additional months. Individuals were then followed up for 3 additional months while receiving aspirin therapy alone. The analysis began in August 2015.. Ischemic events (myocardial infarction not related to stent thrombosis, stent thrombosis, and ischemic stroke) and bleeding events (Global Utilization of Streptokinase and Tissue Plasminogen Activator for Occluded Arteries [GUSTO] classification moderate or severe bleeding).. Ischemic events (myocardial infarction not related to stent thrombosis, stent thrombosis, and ischemic stroke) and bleeding events (GUSTO classification moderate or severe bleeding). Death at 21 months after randomization (33 months after coronary stenting).. In total, 25 682 individuals older than 18 years with an indication for coronary stenting were enrolled, and 11 648 (mean age, 61.3 years; 25.1% female) were randomized. After randomization, 478 individuals (4.1%) had 502 ischemic events (306 with myocardial infarction, 113 with stent thrombosis, and 83 with ischemic stroke), and 232 individuals (2.0%) had 235 bleeding events (155 with moderate and 80 with severe bleeding). Among individuals with ischemic events, 52 (10.9%) died. The annualized mortality rate after an ischemic event was 27.2 (95% CI, 20.3-35.7) per 100 person-years. The cumulative incidence of death after an ischemic event among the total randomized study population was 0.5% (0.3% with myocardial infarction, 0.1% with stent thrombosis, and 0.1% with ischemic stroke). Among individuals with bleeding events, 41 (17.7%) died. The annualized mortality rate after a bleeding event was 21.5 (95% CI, 15.4-29.1) per 100 person-years. The cumulative incidence of death after a bleeding event among the total randomized study population was 0.3% (0.1% with moderate and 0.2% with severe bleeding).. In patients treated with dual antiplatelet therapy for at least 1 year after coronary stenting, ischemic events were more frequent than bleeding events, and both events were associated with high risk of mortality.. clinicaltrials.gov Identifier: NCT00977938.

Triple vs Dual Antithrombotic Therapy in Patients with Atrial Fibrillation and Coronary Artery Disease.
The role of triple antithrombotic therapy vs dual antithrombotic therapy in patients with both atrial fibrillation and coronary artery disease remains unclear. This study explores the differences in treatment practices and outcomes between triple antithrombotic therapy and dual antithrombotic therapy in patients with atrial fibrillation and coronary artery disease.. Using the Outcomes Registry for Better Informed Treatment of Atrial Fibrillation (n = 10,135), we analyzed outcomes in patients with coronary artery disease (n = 1827) according to treatment with triple antithrombotic therapy (defined as concurrent therapy with an oral anticoagulant, a thienopyridine, and aspirin) or dual antithrombotic therapy (comprising either an oral anticoagulant and one antiplatelet agent [OAC plus AA] or 2 antiplatelet drugs and no anticoagulant [DAP]).. The use of triple antithrombotic therapy, OAC plus AA, and DAP at baseline was 8.5% (n = 155), 80.4% (n = 1468), and 11.2% (n = 204), respectively. Among patients treated with OAC plus AA, aspirin was the most common antiplatelet agent used (90%), followed by clopidogrel (10%) and prasugrel (0.1%). The use of triple antithrombotic therapy was not affected by patient risk of either stroke or bleeding. Patients treated with triple antithrombotic therapy at baseline were hospitalized for all causes (including cardiovascular) more often than patients on OAC plus AA (adjusted hazard ratio 1.75; 95% confidence interval, 1.35-2.26; P <.0001) or DAP (hazard ratio 1.82; 95% confidence interval, 1.25-2.65; P = .0018). Rates of major bleeding or a combined cardiovascular outcome were not significantly different by treatment group.. Choice of antithrombotic therapy in patients with atrial fibrillation and coronary artery disease was not affected by patient stroke or bleeding risks. Triple antithrombotic therapy-treated patients were more likely to be hospitalized for all causes than those on OAC plus AA or on DAP.

Duration of dual antiplatelet therapy and long-term clinical outcome after coronary drug-eluting stent implantation: landmark analyses from the CREDO-Kyoto PCI/CABG Registry Cohort-2.
Optimal duration of dual antiplatelet therapy (DAPT) after drug-eluting stent (DES) implantation has not been yet fully elucidated.. We assessed the influence of prolonged thienopyridine therapy on clinical outcomes with landmark analysis at 4 and 13 months after DES implantation. Among 6802 patients with at least 1 DES implantation in the CREDO-Kyoto Registry Cohort-2, 6309 patients (on thienopyridine, 5438 patients; off thienopyridine, 871 patients) and 5901 patients (on thienopyridine, 4098 patients; off thienopyridine, 1803 patients) were eligible for the 4- and 13-month landmark analyses, respectively. The majority of patients had stable coronary artery disease (73%) and received sirolimus-eluting stents (93%), and approximately 90% of thienopyridine was ticlopidine. Patients taking thienopyridine had more complex comorbidities and more complex lesion and procedural characteristics as compared with patients not taking thienopyridine. After adjusting for confounders, thienopyridine use was not associated with decreased risk for death/myocardial infarction/stroke (hazard ratio [HR], 1.13; 95% confidence interval [CI], 0.89-1.43, P=0.32 in the 4-month landmark analysis; HR, 1.14; 95% CI, 0.90-1.45, P=0.29 in the 13-month landmark analysis, respectively), whereas the risk for GUSTO moderate/severe bleeding tended to be higher in patients taking thienopyridine (HR, 1.51; 95% CI, 1.00-2.23, P=0.049 in the 4-month landmark analysis; HR, 1.44; 95% CI, 0.99-2.09, P=0.057 in the 13-month landmark analysis, respectively).. Prolonged thienopyridine therapy beyond 4 and 13 months appeared not to be associated with reduction in ischemic events but to be associated with a trend toward increased bleeding. Optimal duration of DAPT after DES implantation might be shorter than the currently recommended 1-year interval.
