Filter by:The goal of this study is to assess a new non-invasive computerized, multiphase, resting electrocardiogram analysis device in early identification of patients at risk for acute coronary syndrome. The overall objective is to assess the association between the results from a resting MCG and 30-day cardiovascular outcome in patients presenting to the emergency department with suspected coronary disease.
This is a randomized controlled, multi-center, non-blinded non-inferiority study examining the utility of telemetry monitoring in patients admitted who are low risk for acute coronary syndrome. Each of the six sites will prospectively enroll 250 patients in each arm of the study randomized to either a med-surg bed (no telemetry) or a telemetry bed during their admission. Research study coordinators will enroll patients and then follow them throughout their hospital course and record primary and secondary end point events.
This study involves doing platelet function testing in patients who have undergone fibrinolysis. Fibrinolysis (Use of clot busting medicine in heart attack) is the standard of care to restore blood flow in blocked arteries as soon as possible after the "Heart attack" in rural health center where access to cardiac catheterization is one hour away. Fibrinolysis is done by the emergency room physician in a timely fashion to minimize the damage of the myocardium. Additionally anti-platelet regimen as adjuvant for patient undergoing fibrinolysis has been well studied in many trials. In this study investigators will use clopidogrel or ticagrelor in randomized fashion to evaluate anti- platelet effect by measuring efficacy in vivo (pharmacodynamics) and blood levels of both drugs (Pharmacokinetics).
Subjects presenting with probable acute coronary syndromes scheduled for cardiac catheterization will be enrolled in this study. Consented subjects will be randomized to receive ticagrelor started with a loading dose immediately after enrollment versus receiving a loading dose of ticagrelor during cardiac catheterization after diagnostic angiography but prior to stenting. Optical coherence tomography (OCT) will be performed after stenting and the volume of thrombus within the new stent will be measured and compared between the groups.
Subjects with acute coronary syndromes scheduled for cardiac catheterization will be enrolled in this study. Subjects that are to be treated clinically with coronary artery stenting will be randomized to receive a loading dose of clopidogrel versus ticagrelor after diagnostic angiography but prior to stenting. Optical coherence tomography (OCT) will be performed after stenting and the presence of blood clots inside the new stent will be measured and compared between the groups.
Thi is an observational, non interventional, cohort analysis by using administrative databases (drugs treatment, laboratory and diagnostic tests, specialist visits and hospitalizations) of Sicilia region to evaluate treatment patterns of patients after Acute Coronary Syndrome (ACS) event.
Symptoms (chest pain, shortness of breath, dizziness, etc.) and treatment usage (doctor or emergency room visits, testing, hospital days, etc.) in patients with Acute Coronary Syndromes are known to be related to emotional distress (Anxiety, Depression and Anger). In addition, behavioral treatment of emotional distress is known to decrease symptoms, and treatment usage. The present protocol tests whether the addition of a medication known to reduce emotional distress can also reduce symptoms and treatment usage. This will done by recruiting patients with ACS during their hospital stay, randomizing them to receive citalopram or placebo, and then examining their symptoms and treatment usage at 6 months.
The purpose of this study is to evaluate whether patients post PCI receiving clopidogrel who are carriers of at least one CYP 2C19 loss-of-function allele may achieve improved pharmacodynamic efficacy of clopidogrel when treated with the CYP 2C19 enzyme inducing agent, St. John's wort, as compared with placebo. Hypothesis 1. Reduced platelet reactivity is present in patients receiving St. John's wort as compared to placebo when utilized in combination with clopidogrel 2. The combination or St. John's wort and clopidogrel results in enhanced platelet inhibition
The purpose of this study is to determine whether the efficacy of tirofiban (a 25mcg/kg i.v. bolus followed by a 0.15mcg/kg/min i.v. infusion during a percutaneous coronary intervention (PCI) plus two hours after the procedure) is more effective than placebo in the setting of standard therapies (e.g. aspirin, a thienopyridine, and unfractionated heparin or bivalirudin) among patients undergoing PCI, as assessed by the incidence of adverse cardiac ischemic events defined as death, myocardial infarction (MI), and urgent target vessel revascularization (uTVR) within 48 hours following study drug initiation. A secondary objective of this study is to assess whether tirofiban (a 25mcg/kg i.v. bolus followed by a 0.15mcg/kg/min i.v. infusion during a PCI plus two hours after the procedure) is safe compared to placebo in the setting of standard therapies (e.g. aspirin, a thienopyridine, and unfractionated heparin or bivalirudin) among patients undergoing PCI, as assessed by the incidence of non-CABG-related TIMI major bleeding within 48 hours following study drug initiation. Patient enrollment is pending.
The study will see if mechanical impulses delivered by an echocardiographic probe during a continuous infusion of MRX 801 are capable of improving blood flow in smaller heart vessels in patients with acute coronary syndromes.
