Filter by:The purpose of this study was to evaluate the effect of this CR program on the improvement of myocardial function using the three-dimensional speckle tracking echocardiography (3D-STE) in AMI patients.
PCI is considered as the reperfusion strategy of choice for patients with acute STEMI. Data from RCTs and meta-analyses demonstrate a consistent and strong signal towards a significant reduction in MACE among patients with STEMI undergoing primary PCI with newer generation stents with enhanced biocompatibility. The present trial aims at filling the current gap of evidence by providing randomized data to establish the superior clinical outcome with an ultrathin strut third-generation DES with biodegradable polymer designed to improve vascular healing in patients with STEMI undergoing primary PCI, compared to the current state-of-the art second-generation DES with permanent polymer.
Recent studies suggest important gender differences in the pathophysiology and prognosis of ST-segment elevation myocardial infarction (STEMI). This is the first prospective controlled study to assess gender differences in the mechanism of plaque rupture/erosion and thrombus formation in patients presenting with STEMI treated with primary angioplasty. Gender-related mechanisms of plaque rupture or erosion will be investigated using a combination of Quantitative Coronary Angiography (QCA), high resolution Optical Coherence Tomography (OCT) of the culprit vessel and histopathology analyses of thrombus aspirates of the infarct related lesion, performed by independent core laboratories, blinded to group (male or female) and clinical variables. In OCTAVIA; enrollment in a 1:1 ratio according to gender group will be ensured by a computer-assisted matching algorithm for gender and age (< 50, 51-70, and > 70 years). Matching has the purpose to enable enrollment of an even number of male and female patients in balanced age groups. This type of dynamic algorithm is appropriate when the composition of the referral population is not known in advance. The sample size for the OCTAVIA study was calculated on the basis of per patient stent strut coverage (a continuous variable with right skewed distribution) with mean of 97.0% and standard deviation of 4.0% in men, versus mean of 95.0% and standard deviation of 4.0% in women, following XIENCE PRIME™ Everolimus Eluting Coronary Stent System implantation. Thus, aiming for a 5% 2-tailed superiority alpha, an 80% power, and assuming a 1:1 enrollment according to gender, a total of 64 patients per group should be enrolled. Anticipating a 10% dropout rate due to patients lost to follow-up and inadequate imaging (included major side branch sections), the total enrollment is set at 70 patients per group (total population of 140 subjects).
The purpose of this study is To assess percutaneous coronary intervention 's effect on short- and long- term outcomes, and complication incidence in resuscitated victims of cardiac arrest after acute myocardial infarction
During primary percutaneous coronary intervention, distal embolization of thrombus and impaired microvascular perfusion has been associated with an increased mortality. Thrombectomy devices during primary percutaneous coronary intervention may prevent distal embolization by reducing thrombus burden and thus improve microvascular perfusion and reduce mortality.
The study evaluates whether long-term treatment with colchicine reduces rates of cardiovascular events in patients after myocardial infarction. Patients who have suffered a documented acute myocardial infarction within the last 30 days, are treated according to the national guidelines and after having completed any planned percutaneous revascularization procedures associated with their initial infarction will receive either colchicine (0.5 mg per day) or matching placebo (1:1 allocation ratio) for an estimated 2 years period or until the target of 301 primary endpoints has been reached.
Dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 receptor inhibitor, more frequently clopidogrel, represents the standard of care for the long-term secondary prevention of atherothrombotic events in patients with myocardial infarction (MI) or peripheral arterial disease (PAD). However, rates of ischemic recurrences remain high. Vorapaxar is a protease-activated receptor (PAR)-1 inhibitor, which exerts potent inhibition of thrombin-mediated platelet aggregation. Patients with diabetes mellitus (DM) are known to be at increased risk of recurrent atherothrombotic events, which translates into worse outcomes, despite the use of standard of care therapy. This is in part due to the hyperreactive platelet phenotype, which characterizes DM patients, and to inadequate response to oral antiplatelet agents, including clopidogrel. Therefore, vorapaxar is an attractive treatment option for DM patients with a prior MI. The pharmacodynamic (PD) effects of vorapaxar in DM patients and how these may differentiate from non-DM patients has not been explored. Further, the role of vorapaxar as part of a dual antithrombotic treatment regimen combined with clopidogrel (and stopping aspirin) represents another important area of clinical interest. The proposed prospective, parallel-design study conducted in patients post-MI or with PAD with and without DM will aim the assess the pharmacodynamic effects of vorapaxar in addition to standard DAPT with aspirin and clopidogrel as well as in combination with clopidogrel only following aspirin withdrawal.
To study the effect of calcifediol on left ventricular remodeling, mineral metabolism, plasma levels of several prognostic biomarkers and on endothelial function after an anterior myocardial infarction.
Dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 receptor inhibitor represents the standard of care for the long-term secondary prevention of atherothrombotic events in patients with myocardial infarction (MI). However, rates of ischemic recurrences remain high, which may be in part due to the fact that other platelet signaling pathways, such as thrombin-induced platelet aggregation, continue to be activated. Vorapaxar is a protease-activated receptor (PAR)-1 inhibitor, which exerts potent inhibition of thrombin-mediated platelet aggregation. It is approved for clinical use by the Food and Drug Administration for the reduction of thrombotic cardiovascular events in patients with a history of MI or with peripheral arterial disease. However, to date clinical trial experience with vorapaxar has been almost exclusively with the P2Y12 receptor inhibitor clopidogrel and the effects of vorapaxar in combination with antiplatelet therapy including prasugrel or ticagrelor, is largely unexplored. Further, the role of vorapaxar as part of a dual antithrombotic treatment regimen, in addition to a novel P2Y12 receptor inhibitor, with withdrawal of aspirin, represents another important area of clinical interest as it has the potential to maximize ischemic protection while reducing the risk of bleeding. The proposed prospective, randomized, parallel-design, open label, study conducted in a real world clinical setting of post-MI patients will aim to assess the pharmacodynamic effects of vorapaxar in addition to antiplatelet therapy with a novel P2Y12 receptor inhibitor (prasugrel or ticagrelor) with and without aspirin.
This study compares standard treatment plus Extra-Corporal Life Support (ECLS) versus standard treatment alone in patients with cardiogenic shock due to myocardial infarction.
