Few effective porcine models of myocardial infarction (MI) related to platelet thrombus formation are available. In this study, we established a novel porcine MI model and examined the effect of dual antiplatelet therapy (DAPT) with aspirin and prasugrel, a P2Y12 antagonist, using this MI model. Thrombotic MI was photochemically induced using rose bengal. Male miniature pigs were divided into 3 treatment groups: Sham, MI, and DAPT. In the DAPT group, aspirin (10mg/kg, p.o.) and prasugrel (1mg/kg, p.o.) were administered 4h before photo-irradiation...

Cardiovascular disease (CVD) is the leading cause of death in the world and our approach to the control and management of CVD mortality is limited. Nattokinase (NK), the most active ingredient of natto, possesses a variety of favourable cardiovascular effects and the consumption of Natto has been linked to a reduction in CVD mortality. Recent research has demonstrated that NK has potent fibrinolytic activity, antihypertensive, anti-atherosclerotic, and lipid-lowering, antiplatelet, and neuroprotective effects...

PURPOSE: Often, we experience cases of aneurysm shrinkage and no aneurysm shrinkage after successful endovascular aortic aneurysm repair (EVAR), without postoperative endoleaks. We studied these cases to ascertain the predictive factors for aneurysm shrinkage. METHODS: From 2007 to 2014, we selected 255 cases that comprised aneurysm shrinkage (> 4 mm) and no-shrinkage cases (shrinkage from 0 to 4 mm). Excluding 36 cases of endoleaks, 43 cases without one-year follow-up CT scan, and 3 cases of aortic dissection, we assessed 93 cases of aneurysm shrinkage (S group) and 80 cases of no aneurysm shrinkage (N group) at one-year follow-up...

INTRODUCTION: Every fifth ischemic stroke is caused by thromboembolism originating from an atherosclerotic carotid artery plaque. While prevention is the most cost-effective stroke therapy, antiplatelet and cholesterol-lowering drugs have a ceiling effect in their efficacy. Therefore, discovery of novel pathophysiologic targets are needed to improve the primary and secondary prevention of stroke. This article provides a detailed study design and protocol of HeCES2, an observational prospective cohort study with the objective to investigate the pathophysiology of carotid atherosclerosis...

BACKGROUND: Whether prolonged dual antiplatelet therapy (DAPT) improves clinical outcomes after percutaneous coronary intervention for coronary bifurcation lesion is uncertain. METHODS AND RESULTS: We evaluated 2082 patients who were treated with drug-eluting stent for bifurcation lesions and were event free (no death, myocardial infarction [MI], cerebrovascular accident, stent thrombosis, or any revascularization) at 12 months after the index procedure. Patients were divided into 2 groups: DAPT ≥12-month group (n=1776) and DAPT <12-month group (n=306)...

BACKGROUND: Antiphospholipid syndrome (APS) is an autoimmune disease characterised by the presence of antiphospholipid (aPL) antibodies that have prothrombotic activity. Antiphospholipid antibodies are associated with an increased risk of pregnancy complications (recurrent miscarriage, premature birth, intrauterine growth retardation) and thrombotic events (both arterial and venous). The most common thrombotic events include brain ischaemia (stroke or transient ischaemic attack) and deep vein thrombosis...

The introduction of ticagrelor, one of the first directly-acting oral antiplatelet drugs, provided new possibilities in the prevention of thrombotic events in patients with acute coronary syndromes (ACS). Current guidelines recommend ticagrelor in dual antiplatelet therapy with aspirin over clopidogrel for prevention of stent thrombosis in patients with ACS. Moreover, in the management of ACS, lipid-lowering treatment with high-intensity statin therapy is advised for secondary prevention of cardiovascular events over the long term...

Introduction: Cardiovascular (CV) diseases remain a leading global cause of death. It has been proven that the use of acetylsalicylic acid (ASA) in secondary prevention reduces the CV risk, while the benefits of ASA in primary prevention have recently been debated. The aim of the study was to compare the antiplatelet effect of standardised tomato extract (STE) and ASA in hypertensive patients with high CV risk. Material and methods: The study involved high-risk patients with arterial hypertension (AH) randomly assigned to one of two groups: group 1 included 33 patients receiving ASA and group 2 included 32 patients receiving STE...

Platelets play an essential role in haemostasis. Assessment of their function is vital for anaesthesiologists evaluating haemostatic potential, especially during emergency operations. The monitoring of platelets function had been implemented into the European recommendations for management of perioperative and posttraumatic bleeding. One of the diagnostic methods described in the recommendations is multiple electrode aggregometry. As antiplatelet therapy becomes more widely used in modern medicine, this method, in contrast to standard laboratory tests, can significantly help to identify patients with drug-induced thrombocytopaty...
