Filter by:Patients undergoing coronary angioplasty are frequently treated with new drugs that stop blood platelets working and so improve the success of the procedure. Individual patients may vary in the dose of the drug required. New platelet tests have been developed which can be performed near the patient and possibly immediately tell the doctor the degree of platelet inhibition achieved so that the dose can be adjusted accordingly. This study aims to investigate if these platelet tests indicate if new anticoagulants are more effective at inhibiting platelet function than the traditional anticoagulants. The study will demonstrate if these newer drugs improve blood flow through the heart muscle and thereby provide better long term outcomes for patients undergoing percutaneous intervention.
OBJECTIVE: to evaluate the safety and efficacy of a brief intracoronary infusion of ADO applied at the time of reperfusion to limit infarct size and LV remodelling in patients with ACSST submitted to primary ACTP. DESIGN: Multicentric, prospective, randomised, parallel, placebo-controlled double-blind study. PATIENTS: 200 patients older than 18 with ACSST and without prior myocardial infarction receiving primary PTCA within 6 hours after symptom onset.
A prospective, randomized multicenter study of subjects with a high-risk of having a myocardial infarction (MI) due to acute coronary syndrome or bypass surgery. There is no differential intervention administered to the two arms of the ALERTS Study. The study evaluates whether or not a patient alarm from the Guardian System will provide benefit (e.g. shorten pre-hospital delay) compared to symptoms-only ER presentation in the event of a heart attack. An amendment to the data analysis protocol was collaboratively created by AngelMed and FDA, and was adopted by AngelMed on 4/22/2017.
To assess diagnostic and prognostic value of new biomarkers in patients admitted for suspicion of non ST elevation acute coronary syndrome (NSTE ACS).
The purpose of this study is to investigate an oral formulation of RVX000222 for safety, pharmacokinetic and efficacy in healthy subjects.
The purpose of this study is to demonstrate that patients receiving cangrelor infusion before coronary artery bypass grafting have an acceptable safety profile and can undergo surgery without excessive bleeding peri-operatively.
STUDY QUESTIONS - What is the real prevalence of platelet "resistance" to aspirin during the acute phase of stroke and after 3 months, and 1 year, as measured using different platelet function tests? - Do all methods measure similar levels of resistance, or are some methods more sensitive than others? - Does this resistance result in a worse clinical prognosis? Is this result independent of other variables? OBJECTIVES 1. Hospital Phase (Acute Stroke) - Determination, using various methods, of the prevalence of platelet hyperreactivity in patients treated with aspirin to treat ischemic stroke (acute phase) - Comparison of different assessment methods and identification of the most accurate of these - Identification of variables that correlate with platelet hyperreactivity 2. Follow-up Phase - Correlation between platelet hyperreactivity and important clinical outcomes at 12, 24, and 36 months - Correlation between platelet hyperreactivity and death or dependency at hospital discharge, at 3, 12, 24, and 36 months (Modified Rankin Scale) - Correlation between platelet hyperreactivity and recurrent stroke of any type - Correlation between different methods for evaluating platelet functions and identification of the most accurate method - Analysis of hyperreactivity over time THE STUDY - The study will include 200 consecutive patients seen in the emergency department of a large, urban hospital (1500 inpatient beds) and diagnosed with stroke in the acute phase; these patients will be treated with aspirin for an undetermined period - The investigators will not include patients who require full anticoagulation treatment, regardless of the cause - Importantly, the analysis of primary and secondary outcomes will be carried out after blinding the examiner to the results of the platelet aggregation tests PLATELET TESTS - Whole Blood Aggregometer, ChronoLog - VerifyNow, Accumetrics - PFA-100, Siemens - Plateletworks, Helena - Impact-R, Diamed - Serum thromboxane B2
This study randomizes patients seen by Redmond Medic One into a control arm and a study arm when they present with acute coronary syndrome and have non-contributory ECG's (i.e.non-STEMI). The control group is treated normally and delivered to the receiving hospital. The study group is treated normally as well, however troponin measurements are made using an i-STAT blood analyzer prior to hospital arrival. The results are presented to the receiving physician. Door-to-reperfusion time is monitored for both groups.
The Aachener Digitale Myokardinfarkt Register (ADMIRE) is a prospektive registry study which was designed in order to obtain data of patients with acute coronary syndrome and herewith control and optimize guideline conform therapy of these patients.
The purpose of this study is to determine whether intensive lipid lowering and Omega-3 fatty acid are effective in the treatment of coronary atherosclerotic plaque.
