Filter by:This is a Prospective, Observational Multicenter Non-Interventional Cohort Study. The primary objective is to determine whether platelet expression of FcγRIIa is associated with risk of myocardial infarction (MI), stroke and death. Secondary objectives include: 1) Develop a score that combines clinical characteristics plus platelet expression of FcγRIIa to determine the risk of MI, stroke, and death; and 2) Determine whether platelet expression of FcγRIIa is associated with risk of major bleeding. The primary endpoint is the composite of death, MI and stroke. A secondary endpoint is the incidence of clinically significant bleeding according to the Bleeding Academic Research Consortium (BARC) scale type 2-5. Approximately 800 male and female subjects with confirmed MI [ST-segment elevation MI (STEMI) or non-ST-segment elevation MI (NSTEMI)] will be enrolled before hospital discharge for the index event. Approximately 10 sites in the United States will participate in this study. It is anticipated that it will take approximately 12 months to enroll approximately 800 subjects. The study and subject follow-up will continue until 1) at least 80 ischemic events (MI, stroke, and death) have occurred, and 2) the last subject enrolled has completed 18 months of follow-up.
It is planned to include 200 patients hospitalized with primary myocardial infarction with and without ST segment elevation (STEMI or NSTEMI) in combination with COVID-19 within the first 15 days from the disease onset. The total follow-up period is 96 weeks. Hypotheses: 1. An integrated approach in assessing myocardial contractility, regulation of the heart and the structural and functional state of arteries will make it possible to more accurately assess the heart pumping function; explain the mechanisms of the relationship between left ventricular (LV) contractile function and its volumetric indices; to study the mechanisms of ventriculo-arterial coupling and the influence of autonomic regulation, the role of markers of the sudden cardiac death (late ventricular potentials, pathological turbulence of the heart rate, dispersion of the QT interval). 2. In patients who have had myocardial infarction in combination with the new coronavirus infection SARS-CoV-2 (COVID-19), long-term highly effective lipid-lowering therapy, regardless of the drugs prescribed, has an antiarrhythmic effect and has a beneficial effect on the autonomic regulation of the heart rate. Highly effective lipid-lowering therapy leads to an improvement in LV contractility and structural and functional properties of the large arteries. Methods and variables 1.

This protocol describes a study to compare intended trans-radial versus trans-femoral intervention and bivalirudin monotherapy versus current European standard of care consisting of unfractionated heparin (UFH) plus provisional use of glycoprotein IIb/IIIa inhibition via the use of one of the three available agents on the market (e.g. abciximab, tirofiban or eptifibatide) in patients (≥18 years) with ACS, that are intended for an invasive management strategy. This study will be conducted in compliance with Good Clinical Practices (GCP) including the Declaration of Helsinki and all applicable regulatory requirements.
