Anticoagulation in PCI

INTRODUCTION: The preference for using transradial access (TRA) over transfemoral access (TFA) in patients requiring percutaneous coronary intervention (PCI) is based on evidence suggesting that TRA is associated with less bleeding and fewer vascular complications, shorter hospital stays, improved quality of life, and a potential beneficial effect on mortality. We have limited study data comparing the two access routes in a patient population with atrial fibrillation (AF) undergoing PCI, who have a particular increased risk of bleeding, while AF itself is associated with an increased risk of thromboembolism...

BACKGROUND: Although VLST remains an important concern, the underlying etiology and clinical characteristics are not fully elucidated in Japanese patients who undergo intravascular imaging-guided percutaneous coronary intervention (PCI) regularly. METHODS: We identified 50 VLST lesions (BMS [n=16], 1ST generation DES [n=14] and newer generation DES [n=20]) in patients managed in our institutes. The underlying mechanism of VLST was assessed by optical coherence tomography (OCT), and the major etiology of each lesion was determined...

AIM: The "2023 ACC/AHA/ACCP/HRS Guideline for the Diagnosis and Management of Patients With Atrial Fibrillation" provides recommendations to guide clinicians in the treatment of patients with atrial fibrillation. METHODS: A comprehensive literature search was conducted from May 12, 2022, to November 3, 2022, encompassing studies, reviews, and other evidence conducted on human subjects that were published in English from PubMed, EMBASE, the Cochrane Library, the Agency for Healthcare Research and Quality, and other selected databases relevant to this guideline...

The investigation for the optimal anticoagulation strategy for patients with stable coronary artery disease, acute coronary syndromes, and undergoing percutaneous coronary intervention constitutes a great challenge for physicians and is a field of extensive research. Although aspirin is commonly recommended as a protective measure for all patients with coronary artery disease and dual antiplatelet therapy for those undergoing procedures, such as percutaneous coronary intervention or coronary artery bypass graft surgery, the risk of recurrent cardiovascular events remains significant...

INTRODUCTION: Data regarding changes in the arterial vascular wall after the deployment of suture-mediated vascular closure devices (VCD) at the femoral site in patients undergoing percutaneous coronary angiography (CAG) or percutaneous coronary intervention (PCI) are sparse. This study investigated the occurrence of structural vascular changes or adverse vascular complications at the access site in the short term after the deployment of a suture-mediated intravascular VCD. METHODS: Ninety-three patients (72% males) with a mean age of 62 ± 11 years were enrolled...

Cardiovascular disease remains the leading cause of death and morbidity worldwide. Inflammatory responses after percutaneous coronary intervention led to neoathrosclerosis and in-stent restenosis and thus increase the risk of adverse clinical outcomes. In this work, a metabolism reshaped surface is engineered, which combines the decreased glycolysis promoting, M2-like macrophage polarization, and rapid endothelialization property. Anionic heparin plays as a linker and mediates cationic SEMA4D and VEGF to graft electronically onto PLL surfaces...

BACKGROUND: Up to 30% of patients with atrial fibrillation (AF) have coronary artery disease, and many undergo percutaneous coronary intervention (PCI). In the setting of acute coronary syndrome with PCI, or high-risk elective PCI, Canadian AF guidelines recommend 1-30 days of acetylsalicylic acid, 1-12 months of clopidogrel, and oral anticoagulation (OAC) with doses that may change throughout the 12 months post-PCI. The complexity of these regimens may contribute to unplanned modifications (UPMs), increasing the risk of thrombosis and/or bleeding...

PURPOSE OF REVIEW: Advances in pharmacogenomics have paved the way for personalized medicine. Cardiovascular diseases still represent the leading cause of mortality in the world. The aim of this review is to summarize the background, rationale, and evidence of pharmacogenomics in cardiovascular medicine, in particular, the use of antiplatelet drugs, anticoagulants, and drugs used for the treatment of dyslipidemia. RECENT FINDINGS: Randomized clinical trials have supported the role of a genotype-guided approach for antiplatelet therapy in patients with coronary heart disease undergoing percutaneous coronary interventions...

BACKGROUND: Bleeding rates on dual antiplatelet therapy (DAPT) within 1 month after percutaneous coronary intervention (PCI) remain high in clinical practice, particularly in patients with acute coronary syndrome or high bleeding risk. Aspirin-free strategy might result in lower bleeding early after PCI without increasing cardiovascular events, but its efficacy and safety have not yet been proven in randomized trials. METHODS: We randomly assigned 6002 patients with acute coronary syndrome or high bleeding risk just before PCI either to prasugrel (3...

BACKGROUND: Unfractionated heparin (UFH) is the preferred anticoagulant agent in percutaneous coronary intervention (PCI) procedures for minimising the risk of thrombotic complications. Because of the narrow therapeutic range of UFH, some society guidelines have advocated the use of the activated clotting time (ACT) test to monitor anticoagulation intensity during PCI to reduce thrombotic and bleeding complications. We aimed to assess the current practice of UFH prescription and its monitoring in Australia and New Zealand (ANZ)...

Although bivalirudin has been recently made available for purchase in China, large-scale analyses on the safety profile of bivalirudin among Chinese patients is lacking. Thus, this study aimed to compare the safety profile of bivalirudin and heparin as anticoagulants in Chinese ST-segment elevation myocardial infarction (STEMI) patients undergoing percutaneous coronary intervention (PCI). A total of 1063 STEMI patients undergoing PCI and receiving bivalirudin (n=424, bivalirudin group) or heparin (n=639, heparin group) as anticoagulants were retrospectively enrolled...

BACKGROUND: Protein C deficiency is typically associated with venous thromboembolism; however, arterial thrombosis has been reported in several cases. We report the case of a patient with pulmonary thromboembolism and deep vein thrombosis following acute myocardial infarction with high thrombus burden. CASE SUMMARY: A 40-year-old man was diagnosed with pulmonary thromboembolism and deep vein thrombosis without any provoking factors. The patient was treated with anticoagulants for six months, which were then discontinued...

BACKGROUND: Bivalirudin is associated with fewer major bleeding events than heparin in patients undergoing percutaneous coronary intervention (PCI), but confounding effects of concomitant glycoprotein IIb/IIIa inhibitors, routine femoral artery access, and less potent effects of clopidogrel limits meaningful comparisons. The present study is a systematic review and meta-analysis to compare bivalirudin to heparin in contemporary practice. METHODS: The Cochrane Library, PubMed, EMBASE, and Ovid MEDLINE databases were searched for relevant studies, including comparisons between bivalirudin and heparin in the current medical era from inception to December 23, 2021...

INTRODUCTION: Acute myocardial infarction is an important arterial thrombotic event in patients with antiphospholipid syndrome (APS). Anticoagulation regimen might greatly affect the prognosis. Due to the lack of sufficient data and large prospective randomized controlled trials, there is no definite consensus among researchers on the optimal antithrombotic therapy for patients with APS after arterial events. PATIENT CONCERNS: A 35-year-old male presented with sustained chest tightness and chest pain for 6 hours, accompanied with palpitation, sweating and headache...

Ellis type 4 coronary artery perforation (CAP4), also referred to as Ellis type 3 cavity-spilling perforation, is a rare but life-threatening complication of percutaneous coronary intervention characterized by extravasation of blood into a cardiac chamber, anatomic cavity, or coronary sinus or vessel. CAP4 is uncommon, accounting for 1.9% to 3.0% of all CAP. Only 11 cases of CAP4 have been reported in detail; we report an additional two cases and review prior reports of this rare complication. Our first case highlights a patient with chronic anginal symptoms due to a 75% concentric stenotic lesion in the mid-LAD...

INTRODUCTION: Bivalirudin, a bivalent direct thrombin inhibitor, has been developed to reduce bleeding without any trade-off in thrombotic events in acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI). AREAS COVERED: Despite showing a superior safety profile compared with unfractionated heparin (UFH), bivalirudin is not considered the anticoagulant of choice in ACS patients undergoing PCI, mainly because of an increased rate of acute stent thrombosis (ST) showed by several randomized controlled trials (RCTs), in addition to limited availability in certain countries and increased costs...

Concomitant presence of atrial fibrillation and coronary artery disease requiring percutaneous coronary intervention is a frequent occurrence. The choice of optimal antithrombotic therapy, in this context, is still challenging. To offer the best protection both in terms of stroke and stent thrombosis, triple therapy with oral anticoagulation and dual antiplatelet therapy would be required. Several drug combinations have been tested in recent years, including direct oral anticoagulants, with the aim of balancing ischemic and bleeding risk...
