Abstract
PURPOSE The purpose of this study is to assess the efficacy and safety of cilostazol prescription in patients with femoropopliteal peripheral artery disease (PAD) after endovascular therapy (EVT). MATERIALS AND METHODS We conducted a systematic review and meta-analysis of all studies reporting the outcomes of cilostazol after femoropopliteal EVT of PAD up to September 2022. Clinical outcomes of interest included primary patency, in-stent restenosis (ISR), vessel re-occlusion, freedom from target lesion revascularization (TLR), repeat revascularization, all-cause mortality, amputation, major adverse cardiovascular events (MACEs) and major adverse limb events (MALEs), and bleeding complication. RESULTS A total of 4 randomized controlled trials (RCTs) and 8 observational studies containing a total of 4898 patients met the inclusion criteria and were included in this systematic review and meta-analysis. We found that the use of cilostazol was associated with higher primary patency after femoropopliteal artery EVT (odds ratio [OR]=1.67, 95% confidence interval [CI]=1.50-1.87, p<0.001, I2=33.2%), a lower risk of ISR (OR=0.43, 95% CI=0.29-0.63, p<0.001, I2=37.6%), repeat revascularization (OR=0.43, 95% CI=0.24-0.76, p<0.005, I2=27.4%), and vessel re-occlusion (OR=0.59, 95% CI=0.38-0.93, p<0.05, I2=0%). There was an increase in freedom from TLR rate (OR=2.19, 95% CI=1.58-3.05, p<0.001, I2=0%), as well as a reduction in the occurrence of MALEs (OR=0.50, 95% CI=0.29-0.85, p<0.05, I2=0%). However, there was no significant difference in amputation, MACEs, all-cause mortality, and major bleeding complications. Subgroup analysis showed that cilostazol treatment in patients with femoropopliteal drug-eluting stents (DES) implantation remained associated with higher primary patency and a lower risk of ISR. CONCLUSIONS After EVT of femoropopliteal artery lesions, additional oral cilostazol enhances primary patency, reduces the occurrences of ISR and vessel re-occlusion, diminishes the risks associated with MALEs, lowers the need for repeat revascularization, and increases freedom from TLR rates. However, it does not impact amputation, MACEs, all-cause mortality, or major bleeding complications. These findings suggest cilostazol as a potentially safe and effective adjunct therapy in patients with femoropopliteal PAD after EVT. CLINICAL IMPACT After undergoing endovascular therapy (EVT) for femoropopliteal artery lesions, the addition of cilostazol to antiplatelet therapy can significantly improve primary patency, reducing the incidence of in-stent restenosis, repeat revascularization, vessel re-occlusion, and major adverse limb events while increasing freedom from target lesion revascularization rate. The simultaneous use of drug-eluting stents in the femoropopliteal artery lesions, combined with cilostazol, potentially results in a synergistic anti-stenotic effect. This therapeutic approach does not appear to be associated with an increased risk of major bleeding events or all-cause mortality. These findings provide additional evidence supporting the treatment of anti-stenosis in patients with femoropopliteal artery lesions after EVT.

Abstract
Coronary artery calcification is prevalent in coronary heart disease with its progression being predictive of future adverse cardiac events. Its presence is considered to be a marker of interventional procedural complexity. Several adjunctive percutaneous coronary intervention tools, such as modifying balloons, atherectomy devices and intravascular lithotripsy, now exist to successfully treat calcified lesions. In this state-of-the-art review, a step-wise progression of strategies is described to modify coronary plaque, from well-recognised techniques to techniques that should only be considered when standard manoeuvres have proven unsuccessful. Technology has advanced greatly over the past few decades and we discuss how future technologies might shape percutaneous intervention.

Abstract
Cilostazol, a phosphodiesterase III inhibitor, has vasodilating and antiplatelet properties with a low rate of bleeding complications. It has been used over the past 25 years for improving intermittent claudication in patients with peripheral artery disease (PAD). Cilostazol also has demonstrated efficacy in patients undergoing percutaneous revascularization procedures for both PAD and coronary artery disease. In addition to its antithrombotic and vasodilating actions, cilostazol also inhibits vascular smooth muscle cell proliferation via phosphodiesterase III inhibition, thus mitigating restenosis. Accumulated evidence has shown that cilostazol, due to its "pleiotropic" effects, is a useful, albeit underutilized, agent for both coronary artery disease and PAD. It is also potentially useful after ischemic stroke and is an alternative in those who are allergic or intolerant to classical antithrombotic agents (eg, aspirin or clopidogrel). These issues are herein reviewed together with the pharmacology and pharmacodynamics of cilostazol. Large studies and meta-analyses are presented and evaluated. Current guidelines are also discussed, and the spectrum of cilostazol's actions and therapeutic applications are illustrated.

Abstract
Background Type 2 diabetes mellitus is a risk factor for lower extremity arterial disease. Cilostazol expresses antiplatelet, anti-inflammatory, and vasodilator actions and improves the claudication intermittent symptoms. We investigated the efficacy and safety of adjunctive cilostazol to clopidogrel-treated patients with type 2 diabetes mellitus exhibiting symptomatic lower extremity arterial disease, in the prevention of ischemic vascular events and improvement of the claudication intermittent symptoms. Methods and Results In a prospective 2-arm, multicenter, open-label, phase 4 trial, patients with type 2 diabetes mellitus with intermittent claudication receiving clopidogrel (75 mg/d) for at least 6 months, were randomly assigned in a 1:1 ratio, either to continue to clopidogrel monotherapy, without receiving placebo cilostazol (391 patients), or to additionally receive cilostazol, 100 mg twice/day (403 patients). The median duration of follow-up was 27 months. The primary efficacy end point, the composite of acute ischemic stroke/transient ischemic attack, acute myocardial infarction, and death from vascular causes, was significantly reduced in patients receiving adjunctive cilostazol compared with the clopidogrel monotherapy group (sex-adjusted hazard ratio [HR], 0.468; 95% CI, 0.252-0.870; P=0.016). Adjunctive cilostazol also significantly reduced the stroke/transient ischemic attack events (sex-adjusted HR, 0.38; 95% CI, 0.15-0.98; P=0.046) and improved the ankle-brachial index and pain-free walking distance values (P=0.001 for both comparisons). No significant difference in the bleeding events, as defined by Bleeding Academic Research Consortium criteria, was found between the 2 groups (sex-adjusted HR, 1.080; 95% CI, 0.579-2.015; P=0.809). Conclusions Adjunctive cilostazol to clopidogrel-treated patients with type 2 diabetes mellitus with symptomatic lower extremity arterial disease may lower the risk of ischemic events and improve intermittent claudication symptoms, without increasing the bleeding risk, compared with clopidogrel monotherapy.

Abstract
Acute coronary syndromes (ACS) are a global cause of mortality and morbidity that affect millions of lives worldwide. Following atherosclerotic plaque rupture, platelet activation and aggregation are the two major elements that initiate thrombus formation inside a coronary artery, which can obstruct blood flow and cause myocardial ischemia; ergo, antiplatelet therapy forms a major part of the treatment strategy for ACS. Patients with ACS routinely receive dual antiplatelet therapy (DAPT), which consists of aspirin and a platelet P2Y12 inhibitor to both treat and prevent atherothrombosis. Use of platelet glycoprotein (GP) IIb/IIIa inhibitors is now limited due to the risk of severe bleeding and thrombocytopenia. Thus, administration of GPIIb/IIIa inhibitors is generally restricted to bail out thrombotic events associated with PCI. Furthermore, current antiplatelet medications mainly rely on thromboxane A2 and P2Y12 inhibition, which have broad-acting effects on platelets and are known to cause bleeding, which especially limits the long-term use of these agents. In addition, not all ACS patients treated with current antiplatelet treatments are protected from recurrence of arterial thrombosis, since many platelet mechanisms and activation pathways remain uninhibited by current antiplatelet therapy. Pharmacological antagonism of novel targets involved in platelet function could shape future antiplatelet therapies that could ultimately lead to more effective or safer therapeutic approaches. In this article, we focus on inhibitors of promising targets that have not yet been introduced into clinical practice, including inhibitors of GPVI, protease-activated receptor (PAR)-4, GPIb, 5-hydroxytryptamine receptor subtype 2A (5-HT2A), protein disulfide isomerase, P-selectin and phosphoinositide 3-kinase β.

Abstract
BACKGROUND AND OBJECTIVE The results of studies on cilostazol-based triple antiplatelet therapy (TAT) after drug-eluting stent (DES) implantation were inconsistent. To assess the effects of TAT compared with dual antiplatelet therapy (DAT) after DES/second-generation DES implantation, we performed a meta-analysis of randomized controlled trials (RCTs). METHODS All relevant studies evaluated were identified by searching the PubMed, EMBASE, Cochrane Library, and ISI Web of Science databases without time and language limitation. Subgroup analyses were performed to evaluate the efficacy and safety of TAT after second-generation DES implantation. RESULTS Eleven RCTs involving a total of 4684 patients were included. The meta-analysis showed TAT was associated with significant beneficial effects on angiographic findings of in-stent restenosis [risk ratio (RR) 0.645, 95% confidence interval (CI) 0.470-0.885; P = 0.007], in-segment restenosis (RR 0.606, 95% CI 0.450-0.817; P = 0.001), in-stent late loss (RR - 0.095, 95% CI - 0.136 to - 0.054; P < 0.0001), in-segment late loss (RR - 0.100, 95% CI - 0.139 to - 0.061; P < 0.0001), target lesion revascularization (TLR) (RR 0.570, 95% CI 0.430-0.755; P < 0.0001), and target vessel revascularization (TVR) (RR 0.523, 95% CI 0.380-0.719; P < 0.0001). No significant difference was found in outcomes of all-cause death, cardiac death, definite/probable stent thrombosis (ST), non-fatal myocardial infarction (MI), overall bleeding, and major bleeding between the two groups, as well as some minor adverse effects including palpitations, thrombocytopenia, neutropenia, and hepatic dysfunction. However, the incidence rate of rash, gastrointestinal disorders, and headache was significantly higher in TAT. The second-generation DES subgroup showed similar results, except for the indicators of all-cause death (RR 2.161, 95% CI 1.007-4.635; P = 0.048) and hepatic dysfunction (RR 0.176, 95% CI 0.031-0.995; P = 0.049). CONCLUSIONS Compared with DAT, cilostazol-based TAT can significantly improve the angiographic findings of in-stent and in-segment late loss, in-stent and in-segment restenosis, TLR, and TVR after DES/second-generation DES implantation. However, no benefits were observed in outcomes of all-cause death, cardiac death, ST, and MI.

The Dipyridamole Added to Dual Antiplatelet Therapy in Cerebral Infarction After First Acute Myocardial Infarction: A Nationwide, Case-Control Study. Front Neurol 2018; 9:1003. [PMID: 30538667 PMCID: PMC6277508 DOI: 10.3389/fneur.2018.01003] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2018] [Accepted: 11/06/2018] [Indexed: 12/12/2022] Open
Abstract
Background and Purpose: No previous study has compared the impact of dipyridamole-based triple antiplatelet therapy on secondary stroke prevention and long-term outcomes to that of dual antiplatelet therapy (DAPT) in patients with acute myocardial infarction (AMI) and previous stroke. This study aimed to evaluate the impact of dipyridamole added to DAPT on stroke prevention and long-term outcomes in patients with cerebral infarction after first AMI. Methods: This nationwide, case-control study included 75,789 patients with cerebral infarction after first AMI. A 1:4 propensity score matching ratio was adopted based on multiple variables. Finally, the data of 4,468 patients included in the DAPT group and 1,117 patients included in the Dipyridamole-DAPT group were analyzed. Primary outcome was overall survival. Secondary outcomes were cumulative event rate of recurrent MI or stroke, and cumulative intracerebral hemorrhage (ICH) and gastrointestinal bleeding rate. Results: Long-term survival rate was comparable between the two groups (log-rank P = 0.1117), regardless of sex analyses. However, after first year, DAPT subgroup revealed better survival over DAPT-dipyridamole subgroup (log-rank P = 0.0188). In age subgroup analysis, a lower survival rate was detected in younger patients from the Dipyridamole-DAPT group after first year (log-rank P = 0.0151), but no survival difference for older patients. No benefit of Dipyridamole-DAPT was detected for patients after AMI, regardless of the myocardial infarction type. DAPT was superior to Dipyridamole-DAPT in patients who underwent percutaneous coronary intervention (PCI) (log-rank P = 0.0153) and ST elevation myocardial infarction after first year (log-rank P = 0.0019). Dipyridamole-DAPT did not reduce cumulative event rate of recurrent MI or stroke in patients after AMI. Moreover, Dipyridamole-DAPT increased the cumulative ICH rate (log-rank P = 0.0026), but did not affect the cumulative event rate of gastrointestinal bleeding. In Cox analysis, dipyridamole did not improve long-term survival. Conclusions: This nationwide study showed that Dipyridamole-DAPT, compared with DAPT, did not improve long-term survival in patients with stroke after AMI, and was related to poor outcomes after 1 year. Dipyridamole-DAPT did not reduce recurrent rate of MI or stroke, but increased the ICH rate without impacting the incidence of gastrointestinal bleeding.

Abstract
Background In this analysis, we aimed to systematically compare stent thrombosis (ST) and its different subtypes following treatment with DAPT (aspirin + clopidogrel) versus TAPT (aspirin + clopidogrel + cilostazol). Methods Studies were included if: they were randomized controlled trials (RCTs) comparing TAPT (cilostazol + aspirin + clopidogrel) with DAPT (aspirin + clopidogrel); they reported ST or its subtype including definite, probable, acute, sub-acute and late ST as their clinical outcomes. RevMan software (version 5.3) was used to carry out this analysis whereby odds ratios (OR) and 95% confidence intervals (CI) were generated. Results Statistical analysis of the data showed no significant difference in total ST with the addition of cilostazol to the standard DAPT with OR: 0.65, 95% CI: 0.38–1.10; P = 0.11, I2 = 6%. Moreover, when ST was further subdivided and analyzed, still, no significant difference was observed in acute, sub-acute, late, definite and probable ST with OR: 0.48, 95% CI: 0.13–1.74; P = 0.27, I2 = 0%, OR: 0.56, 95% CI: 0.22–1.40; P = 0.21, I2 = 0%, OR: 0.72, 95% CI: 0.23–2.28; P = 0.58, I2 = 0%, OR: 1.18, 95% CI: 0.38–3.69; P = 0.77, I2 = 3% and OR: 0.75, 95% CI: 0.17–3.55; P = 0.70, I2 = 0% respectively. No change was observed during a short term (≤ 6 months) and a longer (≥ 1 year) follow-up time period. Conclusions This current analysis showed no significant difference in stent thrombosis with the addition of cilostazol to the standard dual antiplatelet therapy during any follow-up time period after PCI.

Abstract
OBJECTIVES Compared with dual antiplatelet therapy including aspirin and clopidogrel, triple antiplatelet therapy including cilostazol has a mortality benefit in patients with ST-segment elevation myocardial infarction. However, whether the mortality benefit persists in elderly patients is not clear. METHODS From 2007 to 2014, 1278 patients with ST-segment elevation myocardial infarction who underwent primary percutaneous coronary intervention were retrospectively analyzed. The patients were divided into four groups by age (<75 or ≥75 years; young and elderly, respectively) and antiplatelet strategy (triple or dual antiplatelet therapy). We compared the mortality rates between the triple and dual antiplatelet therapy groups. RESULTS There were 1052 (male, 85%; mean age, 56.3 ± 10.4 years) patients in the young group and 241 (male, 52.7%; mean age, 80.3 ± 4.5 years) patients in the elderly group. In the young and elderly groups, 220 (20.9%) and 28 (12.3%) patients were treated with triple antiplatelet therapy. During a 1-year follow-up period, 80 patients died (4.2% in the young group vs. 15.5% in the elderly group). Kaplan-Meier survival analysis revealed that triple antiplatelet therapy was associated with a lower mortality rate in the young group (log-rank, p = 0.005). Although there were more angiographic high-risk patients in the elderly group, similar mortality rates were reported (log-rank, p = 0.803) without increased bleeding rates (1 vs. 3.6% in the elderly group, p = 0.217). CONCLUSIONS Triple antiplatelet therapy might be a better antiplatelet regimen than dual antiplatelet therapy for patients with ST-segment elevation myocardial infarction. Although this benefit was strong in patients aged <75 years, no definite increase in major bleeding was seen for elderly patients (aged ≥75 years).

Abstract
Background The optimal antiplatelet regimen after in-coronary intervention among patients presenting with complex coronary artery lesions or acute coronary syndrome (ACS) has remained unclear. This study sought to evaluate the clinical outcomes of triple antiplatelet treatment (TAPT) (cilostazol added to aspirin plus clopidogrel) in these patients. Methods The PubMed, EMBASE, MEDLINE, and other Internet sources were searched for relevant articles. The primary end point was major adverse cardiac events (MACE), including all-cause mortality, myocardial infarction, and target vessel revascularization. The incidence of definite/probable stent thrombosis and bleeding were analyzed as the safety end points. Results Eleven clinical trials involving 9,553 patients were analyzed. The risk of MACE was significantly decreased following TAPT after stent implantation in the ACS subgroup (odds ratio [OR]: 0.72; 95% confidence interval [CI]: 0.61–0.85; P<0.001), which might mainly result from the lower risk of all-cause mortality in this subset (OR: 0.62; 95% CI: 0.48–0.80; P<0.001). The risk of bleeding was not increased with respect to TAPT. Conclusion TAPT after stent implantation was associated with feasible benefits on reducing the risk of MACE, especially on reducing the incidence of all-cause mortality among patients suffering from ACS, without higher incidence of bleeding. Larger and more powerful randomized trials are still warranted to prove the superiority of TAPT for such patients.

Role of Cilostazol Therapy in Hemodialysis Patients with Asymptomatic Peripheral Arterial Disease: A Retrospective Cohort Study. BIOMED RESEARCH INTERNATIONAL 2016; 2016:8236903. [PMID: 27747241 PMCID: PMC5055930 DOI: 10.1155/2016/8236903] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/27/2016] [Accepted: 08/11/2016] [Indexed: 12/29/2022]
Abstract
Background. Peripheral arterial disease (PAD) and its relevant complications are more common in hemodialysis (HD) patients, while the evidence regarding antiplatelet therapy in CKD patients is scarce. We retrospectively analyzed the efficacy of cilostazol on outcomes in HD patients with asymptomatic PAD (aPAD). Methods. This cohort study enrolled 217 HD patients (median follow-up time: 5.75 years). Associations between cilostazol use and the outcomes were evaluated by time-dependent Cox regression analysis. Results. During follow-up, 39.5% (47/119) patients used cilostazol for aPAD and 31.8% (69/217) patients died. Cilostazol users had significantly lower CVD and all-cause mortalities (adjusted HR [95% CI]: 0.11 [0.03, 0.51] and 0.2 [0.08, 0.52]) than nonusers. Both death risks were nonsignificantly higher in cilostazol users than in HD patients without aPAD. The unadjusted and adjusted HR [95% CI] of CVD death risk were 0.4 [0.07, 2.12] and 0.14 [0.02, 0.8] for patients with aPAD during follow-up and were 0.74 [0.16, 3.36] and 0.19 [0.04, 0.93] for those with aPAD at initial. Conclusions. In HD patients with aPAD, lower CVD and all-cause mortality rates were observed in low-dose cilostazol user. Further evidences from large-scale prospective study and randomization trial are desired to confirm the effect of cilostazol.

Abstract
OBJECTIVE Coronary stenting is one of the most commonly used approaches to open coronary arteries blocked due to atherosclerosis. However, stent struts can induce stent thrombosis due to altered hemodynamics and endothelial dysfunction, and the microscopic process is poorly understood. The objective of this study was to determine the microscale processes during the initiation of stent thrombosis. METHODS We utilized a discrete element computational model to simulate the transport, collision, adhesion, and activation of thousands of individual platelets and red blood cells in thrombus formation around struts and dysfunctional endothelium. RESULTS As strut height increased, the area of endothelium activated by low shear stress increased, which increased the number of platelets in mural thrombi. These thrombi were generally outside regions of recirculation for shorter struts. For the tallest strut, wall shear stress was sufficiently low to activate the entire endothelium. With the entire endothelium activated by injury or denudation, the number of platelets in mural thrombi was largest for the shortest strut. The type of platelet activation (by high shear stress or contact with activated endothelium) did not greatly affect results. CONCLUSIONS During the initiation of stent thrombosis, platelets do not necessarily enter recirculation regions or deposit on endothelium near struts, as suggested by previous computational fluid dynamics simulations. Rather, platelets are more likely to deposit on activated endothelium outside recirculation regions and deposit directly on struts. Our study elucidated the effects of different mechanical factors on the roles of platelets and endothelium in stent thrombosis.

Abstract
The proper use of antiplatelet agents in the cardiac catheterization laboratory is important for ensuring optimal results in patients undergoing percutaneous revascularization. Understanding the mechanisms by which these drugs exerts their effects is important for both interventional and non-interventional cardiologists. The effects of these agents on platelet function can be assessed and monitored using a variety of commercially available laboratory assays but so far these tests have not been adopted in routine clinical practice. Currently, aspirin, thienopyridines and glycoprotein IIb/IIIa inhibitors are the primary types of antiplatelet drugs being utilized. The use of these drugs and of several newer antiplatelet drugs in the treatment of patients undergoing percutaneous revascularization in the cardiac catheterization laboratory will be discussed, especially in the light of the recently published guidelines.
