Hemorrhagic Complications

Abstract Background Prevention of hemorrhagic complications has emerged as a priority in patients undergoing Percutaneous Coronary Intervention (PCI) in addition to suppressing thrombotic complications. This goal is challenging to achieve in diabetic Acute Coronary Syndrome (ACS) patients as Diabetes Mellitus (DM) itself is a prothrombotic state with more pronounced vascular injury response and have a worse outcome after PCI compared with non-diabetic patients. In patients with ACS, Bivalirudin has been shown to result in similar rates of composite ischemia as Heparin plus GPI (GP IIb /IIIa inhibitor), while significantly reducing major bleeding and has received class I recommendation for PCI by American College of Cardiology (ACC 2013). Whether Bivalirudin is safe and effective specially in diabetic ACS patients undergoing PCI, as compared with Heparin (UFH) monotherapy, is unknown. Purpose To determine and compare the incidence of in-hospital and 30-day hemorrhagic complications and major adverse cardiac events (MACEs) as evidence of safety and efficacy using Bivalirudin versus Heparin in diabetic ACS patients undergoing PCI. Methods 218 diabetic ACS patients (age>18 years and ≤75 years) who underwent PCI from May 2018 to April 2019 at University Cardiac Centre, BSM Medical University, Dhaka, Bangladesh were randomly assigned to have UFH or Bivalirudin. Before the guide wire crossed the lesion, 111 patients in the UFH group received a bolus of 70–100 U/kg (targeted activated clotting time, ACT: 200–250 s). 107 patients in the Bivalirudin group received a loading dose of 0.75 mg/kg, followed by an infusion of 1.75 mg/kg/h for up to 4 hours. 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 complications and MACEs [death, MI, target vessel revascularization (TVR) and stroke]. Results Patients treated with Bivalirudin compared with Heparin had a significantly lower in-hospital incidence of QMI (0% vs. 6%; p=0.03) and major bleeding (0% vs. 7%; p=0.02). However, the incidence of cardiac death, stent thrombosis, TVR were no differences between two groups (p>0.05). There was only one NQMI in the Bivalirudin group as opposed to 8% in the Heparin group in 30 days following stenting (p=0.04). Conclusion In diabetic ACS patients undergoing PCI, Bivalirudin is safe and effective as it reduces immediate and short-term hemorrhagic complications as well as MACEs as compared with Heparin.

Clopidogrel is an analogue of ticlopidine, used for reduction of atherosclerotic events in patients with acute coronary syndrome (ACS), stroke, peripheral arterial disease and for elective percutaneous coronary intervention (PCI). It selectively and irreversibly blocks ADP binding to platelets. Its primary side effect is bleeding. However potentially fatal types of haematological dyscrasia such as aplastic anaemia, neutropenia, thrombocytopenia, pancytopenia may be associated with clopidogrel therapy. A 50 years old diabetic, hypertensive lady with angina was started to treat with clopidogrel along with other anti-ischaemic and anti-hypertensive drugs. Subsequently the patient developed leucopenia and thrombocytopenia after starting of clopidogrel. Five days later her complete blood count returned to normal after withdrawal of both anti platelets. Aspirin was re-introduced with great precaution. Later repeat leucocyte and platelet count were found to be normal. At follow- up 1 month after discharge patient found asymptomatic with normal blood count. To the best of our knowledge, clopidogrel induced haematological dyscrasia was not reported earlier in our country. Key words: Acute coronary syndrome; percutaneous coronary intervention.

Objective: To determine and compare the incidence of in-hospital and 30-day hemorrhagic complications and major adverse cardiac events (MACEs) as evidence of safety and efficacy using Bivalirudin versus Heparin in diabetic acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI) in a tertiary care cardiac hospital. Background: Prevention of hemorrhagic complications has emerged as a priority in patients undergoing PCI in addition to suppressing thrombotic complications. This goal is challenging to achieve in diabetic ACS patients as DM itself is a prothrombotic state with more pronounced vascular injury response and have a worse outcome after PCI compared with non-diabetic patients. In patients with ACS, Bivalirudin has been shown to result in similar rates of composite ischemia as Heparin plus GPI (GP IIb /IIIa inhibitor), while significantly reducing major bleeding and has received class I recommendation for PCI. Whether Bivalirudin is safe and effective in diabetic ACS patients undergoing PCI, as compared with Heparin (UFH) monotherapy, is unknown. Methods: 218 diabetic ACS patients (age>18 years and ≤ 75 years) who underwent PCI from May 2018 to April 2019 at UCC, BSMMU, Dhaka, Bangladesh were randomly assigned to have UFH or Bivalirudin. Before the guide wire crossed the lesion, 111 patients in the UFH group received a bolus of 70-100 U/kg (targeted activated clotting time, ACT: 200-250 s). 107 patients in the Bivalirudin group received a loading dose of 0.75 mg/kg, followed by an infusion of 1.75 mg/kg/h for up to 4 hours. 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 complications and MACEs [death, MI, target vessel revascularization (TVR) and stroke]. Results: Patients treated with Bivalirudin compared with Heparin had a significantly lower in-hospital incidence of QMI (0% vs. 6%; p=0.03) and major bleeding (0% vs. 7%; p=0.02). However, the incidence of cardiac death, stent thrombosis, TVR were no differences between the groups (p>0.05). There was only one NQMI in the Bivalirudin group as opposed to 8% in the Heparin group in 30 days following stenting (p=0.04). No other adverse effects were found significantly different between groups in 30 days of PCI. Conclusion: In this small scale, prospective, randomized controlled study of diabetic ACS patients undergoing PCI in a single center showed that Bivalirudin is safe and effective as it reduces immediate and short-term hemorrhagic complications as well as MACEs as compared with Heparin.

Periprocedural Myocardial Infarction

Background: Periprocedural myocardial infarction is a common complication following percutaneous coronary intervention. The present study was conducted with an aim to compare the safety and efficacy of loading doses of ticagrelor versus clopidogrel in preventing periprocedural myocardial infarction in Asian patients with acute coronary syndrome undergoing elective percutaneous coronary intervention. Methods: A total of 114 patients with acute coronary syndrome undergoing elective percutaneous coronary intervention were assigned to clopidogrel group (n = 57, the loading and maintenance doses were 300 and 75 mg qd for clopidogrel, and 300 and 100 mg qd for aspirin), or ticagrelor group (n = 57, the loading and maintenance doses were 180 and 90 mg bid for ticagrelor, and 300 and 100 mg qd for aspirin). Cardiac biomarkers were measured before, 8 hours, and 24 hours after percutaneous coronary intervention. The percutaneous coronary intervention–related periprocedural myocardial infarction was defined according to the fourth universal definition of myocardial infarction (2018). Results: The overall incidence of percutaneous coronary intervention–related periprocedural myocardial infarction was 21.1%. The ticagrelor group showed a significantly lower incidence of periprocedural myocardial infarction (12.3% vs 29.8%, p = 0.022) and numerically lower bleeding events (3.5% vs 8.8%, p = 0.242) as compared with clopidogrel group. No patient had major adverse cardiovascular events during the 1-month follow-up. The levels of high-sensitivity C-reactive protein did not differ significantly between the two groups (p > 0.05), indicating that the benefits of ticagrelor were not from its anti-inflammatory effects. Multivariable analysis showed that the use of ticagrelor (odds ratio: 0.50; 95% confidence interval: 0.29-0.87; p = 0.014) and number of stents (odds ratio: 2.75; 95% confidence interval: 1.25-6.06; p = 0.012) were independent predictors of periprocedural myocardial infarction. Conclusion: Pretreatment with a loading dose of ticagrelor seems to be superior in reducing the incidence of percutaneous coronary intervention–related periprocedural myocardial infarction in Asian patients with acute coronary syndrome as compared with clopidogrel.
