Active clinical trials for "Acute Coronary Syndrome"

The primary goal of the PRAISE study is to develop a diagnostic algorithm that allows the prediction of acute coronary syndrome in stroke patients with elevated levels of cardiac troponin.

Blood tests may be able to quickly identify and exclude patients that are having a heart attack. Using these tests in the Emergency Department (ED) may lead to faster treatment, a reduced wait time, and quicker discharge for patients presenting with symptoms suggestive of a heart attack.

It is hypothesized that patients with low pre-PCI serum levels of sRAGE should receive DES implantation and/ or procedures taken to increase serum levels of sRAGE and/ or decrease the serum levels of AGE. The purpose of this pilot study is to afford invasive cardiologists with additional evidenced based information to guide their decision as to which patients should receive a BMS or DES for coronary implantation. The objectives of the study are to determine whether or not: Patients with low pre-PCI serum levels of sRAGE who receive bare metal stents develop restenosis Patients with high pre-PCI serum levels of sRAGE who receive bare metal stents will have reduced risk of the development of restenosis Patients with low pre-PCI serum levels of sRAGE who receive drug eluting stents will have an increased risk of the development of restenosis

In order to further clarify the interaction of PPIs with clopidogrel anti - platelet effect , the investigators designed a clinical randomized controlled trials of omeprazole and pantoprazole antiplatelet effect of clopidogrel .In this experiment , the investigators have taken a randomized NSTE-ACS hospitalized patients met the inclusion criteria were randomly divided into omeprazole and pantoprazole groups . On the day of admission , all patients taking clopidogrel loading dose 300mg + aspirin 300mg and the subsequent maintenance dose of clopidogrel 75mg + aspirin 300mg and omeprazole group taking omeprazole 20mg / d , pantoprazole group taking pantoprazole 20mg / d. Respectively, on the day of admission ( before medication ) , medication for 12-24 hours , medication after 72 hours , 30 days , each taken early morning fasting venous blood again , measuring AA 、ADP - induced platelet aggregation . And selected 30 days , 6 months and 12 months to record the patient's clinical adverse events ( including death , myocardial infarction , and any revascularization , stent thrombosis , recurrent angina , rehospitalization due to cardiovascular disease , bleeding events) . To assess the impact of PPIs on clopidogrel antiplatelet effect by observing 1 year follow-up results , and further explore the optimal combination of dual anti-platelet and joint PPIs course of treatment , appropriate dosage and the best time to provide reasonable for clinical programs to create a personalized treatment system , improve the patient's quality of life .

The current study is a randomized controlled trial, being conducted at two hospitals in Toronto, Ontario, Canada, involving the randomization of cardiac inpatients into an intervention group, in which they will receive mentorship from a volunteer cardiac rehabilitation peer mentor, and a control group, in which they will receive usual care. Patients in both groups will be tracked to determine if they are referred to cardiac rehabilitation and if they enroll in cardiac rehabilitation. We hypothesize that compared to cardiac inpatients who receive usual care, those cardiac inpatients who receive cardiac rehabilitation peer mentorship will be more likely to be referred to and enroll in cardiac rehabilitation.

This prospective study aimed to validate a new prognostic approach of endothelial progenitor cells associated biomarkers in patients with acute coronary syndromes . Recruitment is made prospectively by two centers of Inter -region South Mediterranean,

This is a randomized, open trial comparing post discharge interventions by community health workers (CHW) to standard care in acute coronary syndrome (ACS) patients. This trial will be conducted in 10 hospitals in India/different parts(both secondary and tertiary care). A total of 800 patients will be recruited, with equal allocation to SPREAD interventions and control groups (usual care)

This study is being done to assess the effects of the CTP inhibitor on the function of your platelets (cells within your blood that are involved in the formation of blood clots) and to assess whether you have responded to the ticagrelor well enough to prevent the formation of blood clots within the stent or site in which angioplasty was performed. Recent studies have looked at how racial differences can affect platelet reactivity, the way blood clots. But these studies have not looked at the way different racial backgrounds can affect the way the blood forms clots. Minorities, such as African-Americans are underrepresented. Therefore, we are conducting this platelet reactivity study to better understand if there are differences in how this drug affects African-Americans from how they affect Caucasian patients undergoing percutaneous coronary intervention and receiving ticagrelor. These data will be compared to a historical control of Caucasian patients who underwent similar platelet function testing.

This prospective cohort study will provide information about: characteristics of Rivaroxaban use in patients who are prescribed Rivaroxaban for the first time compared to patients who are prescribed Warfarin for the first time, the occurrence of intracranial haemorrhage, gastrointestinal and urogenital bleeding, and the occurrence of non-infective liver disease.

This prospective cohort study will provide information about: characteristics of Rivaroxaban use in patients who are prescribed Rivaroxaban for the first time compared to patients who are prescribed Phenprocoumon for the first time, the occurrence of intracranial haemorrhage, gastrointestinal and urogenital bleeding, and the occurrence of non-infective liver disease.
