Comprehensive safety profile evaluation of bivalirudin in Chinese ST-segment elevation myocardial infarction patients receiving percutaneous coronary intervention: a prospective, multicenter, intensive monitoring study. BMC Cardiovasc Disord 2022; 22:290. [PMID: 35752771 PMCID: PMC9233771 DOI: 10.1186/s12872-022-02716-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2021] [Accepted: 01/12/2022] [Indexed: 11/30/2022] Open
Abstract
Background This prospective, multi-center, intensive monitoring study aimed to systematically assess the occurrence of adverse events (AEs) and adverse drug reactions (ADRs), especially thrombocytopenia and bleeding, as well as their risk factors in Chinese ST-segment elevation myocardial infraction (STEMI) patients receiving bivalirudin as anticoagulant for percutaneous coronary intervention (PCI). Methods In total, 1244 STEMI patients undergoing PCI and receiving bivalirudin as anticoagulant were enrolled in the present study. Safety data were collected from hospital admission to 72 h after bivalirudin administration; in addition, patients were further followed up at the 30th day with safety data collected at that time. Results AEs, severe AEs, ADRs and severe ADRs were reported in 224 (18.0%), 15 (1.2%), 49 (3.9%) and 5 (0.4%) patients, respectively. Importantly, 4 (0.3%) patients were submitted to hospitalization and 6 (0.5%) patients died due to AEs, while 1 (0.1%) patient was submitted to hospitalization but no (0.0%) patient died due to ADRs. Meanwhile, thrombocytopenia and bleeding occurred in 24 (1.9%) and 21 (1.7%) patients, respectively. Further multivariate logistic analysis identified several important independent factors related to AEs, ADRs, thrombocytopenia or bleeding, which included history of cardiac surgery and renal function impairment, high CRUSADE risk stratification, elective operation and combination with glycoprotein IIb/IIIa inhibitors. Moreover, 4 multivariate models were constructed based on the above-mentioned factors, which all showed acceptable predictive value for AEs, ADRs, thrombocytopenia and bleeding, respectively. Conclusion Bivalirudin is a well-tolerant anticoagulant in Chinese STEMI patients undergoing PCI procedure.

Zhang J, Ding G. Improved Cardiac Function and Attenuated Inflammatory Response by Additional Administration of Tirofiban during PCI for ST-Segment Elevation Myocardial Infarction Patients. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2021; 2021:8371996. [PMID: 34221091 PMCID: PMC8221867 DOI: 10.1155/2021/8371996] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/28/2021] [Accepted: 06/10/2021] [Indexed: 12/22/2022]
Abstract
ST-segment elevation myocardial infarction (STEMI) is one of the acute coronary syndromes, and it is the main cause of cardiac death worldwide. The purpose of this study was to investigate whether tirofiban improves cardiac function and attenuates inflammatory response in STEMI patients undergoing percutaneous coronary intervention (PCI). From May 2016 to May 2019, a total of 124 patients who admitted into our hospital due to STEMI fulfilled inclusion and exclusion criteria and were randomly assigned to PCI + tirofiban and PCI groups, 62 cases per groups. Intravenous administration of 10 μg kg-1 min-1 tirofiban was performed 30 min prior to PCI. During PCI, tirofiban infusion through a micropump with 0.15 μg kg-1 min-1 lasted for 48 h. It was found that the PCI + tirofiban group was significantly different from the PCI group in total corrected TIMI frame count (CTFC) after PCI (15.88 ± 5.11 vs. 22.47 ± 6.26, P < 0.001). At day 7 and day 30 post-PCI, a significant time-dependent decrease in the levels of brain natriuretic peptide (BNP), cardiac troponin I (cTnI), and creatine kinase isoenzyme (CK-MB) in both groups was observed after PCI (P < 0.001). More importantly, the patients in the PCI + tirofiban group had much lower levels of BNP, cTnI, and CK-MB compared with those in the PCI group at days 7 and 30 post-PCI (P < 0.001). At day 7 following PCI, the left ventricular ejection fraction (LVEF) was statistically higher in the PCI + tirofiban group than in the PCI group (P < 0.05). At day 30 post-PCI, increased LVEF concomitant with reduced left ventricular end diastolic diameter (LVEDD) and left ventricular end systolic diameter (LVESD) was observed in the PCI + tirofiban group compared with the PCI group. At day 7 and day 30 post-PCI, both groups displayed a time-dependent decline in the levels of C reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and procalcitonin (PCT) after PCI (P < 0.05). Additionally, the patients in the PCI + tirofiban group had lower levels of CRP, TNF-α, IL-6, and PCT compared with those in the PCI group at days 7 and 30 post-PCI (P < 0.05). All patients in the PCI + tirofiban and PCI groups were followed up for 12 months by outpatient or telephone after discharge. There were fewer patients with LVEF < 50% in the PCI + tirofiban group than the PCI group (P=0.044). Furthermore, it was found that the incidence rate of major adverse cardiovascular events (MACEs) in the PCI + tirofiban group was evidently lower than that in the PCI group (12.90% vs. 29.03%, P=0.028). Taken together, our data suggest that additional administration of tirofiban could improve cardiac function and attenuate inflammatory response in STEMI patients undergoing PCI, which is worthy of promotion in clinic.

Abstract
Evans syndrome (ES) is a rare combination of autoimmune hemolytic anemia and thrombocytopenia. This case report details an old male ES patient with acute myocardial infarction. He was successfully treated by primary percutaneous coronary intervention in the case of low hemoglobin level (60 g/L). Considering ES recurrence after surgery, he was given human immunoglobulin, methyl prednisolone and TPO treatment. On the basis of his platelet count, the patient was required to take only one anti-platelet drug or stop all anti-platelet drugs. To the best of our knowledge, this is the first report of ES with AMI. This case suggests that primary PCI can be a useful therapeutic strategy even if patient has low hemoglobin level, but careful balance between anti-platelet therapy and efforts to raise platelet count are needed after surgery.

Abstract
Atrial fibrillation is the commonest arrhythmia worldwide and is a growing problem. AF is responsible for 25% of all strokes, and these patients suffer greater mortality and disability. Warfarin has traditionally been the only successful therapy for stroke prevention, but its limitations have resulted in underutilisation. Major progress has been made in AF research, leading to improved management strategies. Better risk stratification permits identification of truly low-risk patients who do not require anticoagulation and we are able to simplify ourevaluation of a patient's bleeding risk.The advent of novel anticoagulants means warfarin is no longer the only choice for stroke prophylaxis. These drugs circumvent many of warfarin's inconveniences, but onlylong-term study and use will conclusively demonstrate how they compare to warfarin. The landscape of stroke prevention in AF has changed with effective alternatives to warfarin available for the first time in 60 years-but each new option brings new considerations.

Abstract
Abstract Thrombosis is an underlying cause of many cardiovascular disorders, and generation of thrombi in the arterial circulation can lead to unstable angina, myocardial infarction, or ischemic stroke. Antithrombotic therapy is widely used, with proven benefit to prevent ischemic stroke and thromboembolic events in patients with atrial fibrillation (AF) or to prevent further ischemic complications in patients with acute coronary syndrome (ACS). Traditional anticoagulants (including unfractionated heparin, low-molecular-weight heparin, and warfarin) and antiplatelet agents (including aspirin, clopidogrel, and prasugrel) are typically used for these indications. Limitations to their use include variable pharmacokinetic and pharmacodynamic profiles, inability to inhibit fibrin-bound thrombin, risk of heparin-induced thrombocytopenia, delayed onset of action, numerous drug interactions, need for substantial laboratory monitoring and dosage titrations, hyporesponsiveness or resistance, hypersensitivity, adverse events, and bleeding. To overcome some of the limitations of traditional agents, new antithrombotic agents under development are highly selective for specific coagulation factors blocking the synthesis of thrombin. Clinicians must have an understanding of the new anticoagulants to aid in the selection of appropriate therapies for patients. We describe the most relevant phases II and III clinical trials that evaluated several recent emerging anticoagulant drugs for use in patients with AF or ACS. The advantages of many new agents include predictable pharmaco-dynamic response and pharmacokinetic parameters, allowing for fixed oral dosing with no need for laboratory monitoring. For patients with AF, dabigatran is already approved for the prevention of stroke and systemic embolism, rivaroxaban appears to be an effective alternative to warfarin in high-risk patients, and apixaban may also be an effective alternative to aspirin in patients unable to take warfarin. Otamixaban shows promise as an intravenous alternative for patients with ACS in the acute care setting. Likewise, rivaroxaban, dabigatran, and darexaban with or without dual antiplatelet therapy may be beneficial for secondary prevention of ischemic events in patients with ACS.

Abstract
The advent of potent antiplatelet and antithrombotic agents over the past decade has resulted in significant improvement in reducing ischemic events in acute coronary syndrome (ACS). However, the use of antiplatelet and antithrombotic combination therapy, often in the settings of percutaneous coronary intervention (PCI), has led to an increase in the risk of bleeding. In patients with non-ST elevation myocardial infarction treated with antithrombotic agents, bleeding has been reported to occur in 0.4%-10% of patients, whereas in patients undergoing PCI, periprocedural bleeding occurs in 2.2%-14% of cases. Until recently, bleeding was considered an intrinsic risk of antithrombotic therapy, and efforts to reduce bleeding have received little attention. There have been increasing data demonstrating that bleeding is associated with adverse outcomes, including myocardial infarction, stroke, and death. Therefore, it is imperative to optimize patient outcomes by adopting pharmacological and nonpharmacological strategies to minimize bleeding while maximizing treatment efficacy. In this paper, we present a review of the bleeding classifications used in large-scale clinical trials in patients with ACS and those undergoing PCI treated with antiplatelets and antithrombotic agents, adverse outcomes, particularly mortality associated with bleeding complications, and suggested predictive risk factors. Potential mechanisms of the association between bleeding and mortality and strategies to reduce bleeding complications are also discussed.
