Objective: To determine and compare the incidence of in-hospital and 30-day hemorrhagic complication and major adverse cardiac events (MACEs) as evidence of safety and efficacy using three different anti- thrombotic strategies using Bivalirudin, Heparin plus Eptifibatide (GPI: GP IIb/IIIa inhibitor), and Unfractionated Heparin (UFH) monotherapy in acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI) in a tertiary care cardiac hospital. Background: UFH or Heparin plus Eptifibatide or Bivalirudin is the most commonly used antithrombotic regimen to improve peri and post-PCI clinical outcomes in a patient undergoing PCI for ACS. Among them, the most effective and optimal antithrombotic regimen for preventing ischemic complications while limiting bleeding risk in ACS patients undergoing PCI is still far from being clear. Methods: 324 ACS patients ( age >18 years and ≤75 years) who underwent PCI from May 2018 to May 2019 at UCC, BSMMU, Dhaka were consecutively enrolled in the study and were divided into three groups according to antithrombotic. The choice of Anti-thrombotic strategy was at the discretion of the operator(s) and the patient’s affordability. Group-A: 107 patients received Bivalirudin as intravenous (I/V) bolus of 0.75 mg/ kg, followed by an infusion of 1.75 mg/kg/hr up to 4 hours. Group-B: 111 patients received UFH as an I/ V bolus of 70-100 U/kg (targeted ACT: 250-300 s). Group-C: 106 patients were administered UFH plus Eptifibatide as per the standard hospital guidelines. Dual antiplatelet (DAPT) loading as Aspirin 300 mg plus P2Y12 inhibitors ( Clopidogrel 600 mg or Prasugrel 60 mg or Ticagrelor 180 mg) was given in all patients before the procedure. The maintenance dose of DAPT was continued for at least one month and patients were followed telephonically up to 30 days. The outcome measures were in-hospital and 30-day hemorrhagic complication and MACEs [death, MI, stroke, stent thrombosis and target-vessel revascularization (TVR)] Results: In-hospital outcome: Patients treated with Bivalirudin as compared with UFH had a significantly lower incidence of QMI lesions (0% vs.6%; p=0.038) and major bleeding (0% vs. 7%; p=0.021). The bleeding rate was also significantly lower in Bivalirudin arm as compared with Heparin plus GPI arm (0% vs. 6%; p=0.038). However, the incidence of cardiac death, stent thrombosis, TVR were no differences among the three groups. 30-day outcome: There was only one NQMI in the bivalirudin group as opposed to 8% in the heparin group (p=0.041). No other adverse effects were found significantly different among the study groups. Conclusion: In this perspective, observational study of ACS patients undergoing PCI in a single-center showed that Bivalirudin monotherapy is safer than other contemporary antithrombotic strategies. In terms of efficacy, Bivalirudin is non inferior to Heparin plus Eptifibatde but superior to UFH monotherapy. University Heart Journal Vol. 17, No. 2, Jul 2021; 91-98

Aims. The goal of this study was to evaluate the performance of the InspironTM coronary stent (Scitech Medical™, Goiás, Brazil). The InspironTM sirolimus-eluting stent uses an ultrathin L-605 cobalt-chromium alloy with a 75 μm strut thickness platform coated with an abluminal biodegradable polymer. The polymer is eliminated from the body through the tricarboxylic acid cycle in 6–9 months, releasing 80% of the drug within 30 days after its deployment. Methods. It was a prospective, single-center registry. To represent clinical practice, all patients undergoing percutaneous coronary intervention were included in this registry. There were no exclusion criteria. Clinical follow-ups were performed at twelve months. The endpoints were the occurrence of all-cause death, definite stent thrombosis, and new revascularization. Results. Between November 2017 and May 2019, 790 patients were included (1067 lesions). The mean age was 60.42 ± 14.94 years, and 74.7% presented with acute coronary syndrome. Diabetes mellitus was present in 43.9% of patients, and previous myocardial infarction and previous percutaneous coronary intervention were present in 17.9% and 11.3%, respectively. Angiographic success was achieved in 99.1%. The incidence of all-cause death was 11.5% (6.2% in-hospital and 5.3% in the follow-up) and definitive stent thrombosis was 0.2%. New revascularization was performed in only 5.8% (target lesion revascularization: 2.2%; progression of disease in another lesion: 3.6%). Based on the multivariate regression analysis, only chronic renal failure was an independent predictor of adverse events (OR: 3.3; 95% CI: 1.22–8.92). Conclusion. The result of this single-center registry demonstrates the safety and excellent performance of the InspironTM stent in daily clinical practice with a low rate of adverse cardiac events.

Purpose: to elucidate independent clinical and laboratory predictors of adverse cardiovascular events (ACVE) in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI) with stenting in early inhospital period.Materials and methods. We included in this prospective single center study 130 patients with ACS who underwent PCI with stenting. All patients prior to and after PCI received dual antiplatelet therapy with acetylsalicylic acid and clopidogrel. In 12–48 hours after PCI we measured residual platelet reactivity (RPR) using light aggregometry. In 57 patients simultaneously we performed genotyping of CYP2C19*2 polymorphisms. The following ACVE were used as end­points and were registered during inhospital observation (mean duration 9.7±3.2 days): sudden death, stent thrombosis, arterial thrombosis of other localization, recurrent angina, cardiac rhythm disturbances requiring special therapy.Results. Repetitive ACVE were observed in 32 patients. According to unifactorial regression analysis risk factors of their development were, ADP F­induced RPR (р<0.001), levels of creatinine (р<0.001), hemoglobin (р<0.001), and glucose (р=0.026), age (р=0.01), iron­deficiency anemia (р=0.01), left ventricular ejection fraction (р=0.004), number of stents (р=0.015). According to results of multifactorial regression analysis independent predictors of ACVE were: ADP­induced RPR >76 % (р=0.003), levels of creatinine >189 µmol / L (р=0.003), and hemoglobin <114 g / L (р=0.004). Significant effect of homozygous carriage of CYP2C19*2 (G681A) (А / А) on development of stent thrombosis was also detected (р=0.028).Conclusion. ADP­induced RPR, levels of creatinine and hemoglobin were found to be independent predictors of inhospital ACVE after myocardial revascularization with stenting in patients with ACS.

Objective. The effect of postdilation in patients with acute coronary syndrome is still controversial. This meta-analysis aims to analyze the clinical and angiographic outcomes of postdilation after percutaneous coronary intervention in patients with acute coronary syndrome. Methods. PubMed, Embase, the Cochrane Library, Web of Science, CNKI, and Wangfang databases were searched from inception to August 30, 2020. Eligible studies from acute coronary syndrome patients treated with postdilation were included. The primary clinical outcome was major adverse cardiovascular events (MACE), the secondary clinical outcomes comprised all-cause death, stent thrombosis, myocardial infarction, and target vessel revascularization, and the angiographic outcomes were no reflow and slow reflow. Results. 11 studies met inclusion criteria. In clinical outcomes, our pooled analysis demonstrated that the postdilation had a tendency of decreasing MACE (OR = 0.67, 95% CI 0.45–1.00; P  = 0.05) but significantly increased all-cause death (OR = 1.49, 95% CI 1.05–2.12; P  = 0.03). No significant difference existed in stent thrombosis (OR = 0.71, 95% CI 0.40–1.26; P  = 0.24), myocardial infarction (OR = 1.40, 95% CI 0.51–3.83; P  = 0.51), and target vessel revascularization (OR = 0.61, 95% CI 0.21–1.80; P  = 0.37) between postdilation and non-postdilation groups. In angiographic outcomes, there were no significant differences in no reflow (OR = 1.19, 95% CI 0.54–2.65; P  = 0.66) and slow reflow (OR = 1.12, 95% CI 0.93–1.35; P  = 0.24) between two groups. Conclusions. The postdilation tends to reduce the risk of MACE but significantly increases all-cause death, without significantly affecting stent thrombosis, myocardial infarction, target vessel revascularization, and coronary TIMI flow grade. However, more randomized controlled trials are required for investigating the effect of postdilation for patients with acute coronary syndrome (registered by PROSPERO, CRD42020160748).
