Low Dose Ticagrelor Versus Low Dose Prasugrel in Patients With Prior Myocardial Infarction
Myocardial InfarctionDiabetes Mellitus2 moreTaken together the results from DAPT and PEGASUS-TIMI54, it appears that physicians may consider extending beyond 1 year or reinitiating treatment with a thienopyridine or ticagrelor 60mg bid in patients with a prior MI and features of high ischemic and low bleeding risk. Comparative clinical or pharmacodynamic studies, however, between prasugrel 5 mg od and ticagrelor 60 mg bid in the chronic phase of stable post MI patients have not been performed. In light of this, we believe that a dedicated pharmacodynamic study of ticagrelor 60 bid mg vs prasugrel 5 mg od in a PEGASUS-like population would be informative for the practicing clinician, thus setting the rationale for conducting this specifically designed investigation.

Stem Cell in Acute Myocardial Infarction
Acute Myocardial InfarctionThe study will perform UC-MSCs transplantation in 2 groups and 1 control group with standard treatment. Each group consists of 5 subjects. In the first group UC-MSCs will be transplanted via intravenous (IV) route and the second group via intracoronary (IC) route. The IV group will receive 2 million cells/kg for each subject and the dosage of IC group is 50 million cells for each subject. All groups will be observed until 1 year.

Posterior Circulation ASTRAL Prognostic Score
Stroke IschemicStroke Acute1 moreThe goal of this study is to develop a prognostic score for ischemic posterior circulation strokes, based on our previous work on with the ASTRAL scores (Acute STroke Registry and Analysis of Lausanne) on overall stroke prognosis, intracranial occlusion, recanalization and stroke recurrences. The main question it aims to answer is the modified Rankin score in 3 months after the event. Participants will be patients with acute ischemic stroke of the posterior circulation with mRS priot to event <3. All the data will be collected retrospectively from patients included in the ASTRAL registry between January 2003 and December 2021. The ASTRAL registry will be used as the derivation cohort of the score. Demographics, acute glucose, NIHSS score and acute imaging of each participant will be used from the derivation cohort in order to create an integer-based prognostic score. After internal validation, we plan to validate the score in external stroke registries to show its validity.

Culprit-first in Primary Percutaneous Coronary Intervention
Coronary Artery DiseaseIschemic Heart Disease3 moreThe aim of this study is to assess the impact of culprit-first versus culprit-last percutaneous coronary intervention on the door to balloon time and clinical outcomes in patients with ST-elevation myocardial infarction.

Platelet Inhibition After Pre-hospital Ticagrelor Using Fentanyl Compared to Morphine in Patients...
Acute Myocardial InfarctionProspective, randomized, open-label, single-center, investigator-initiated trial, including patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI) within 12 hours of the symptom's onset. The study aims to compare platelet inhibition (pharmacodynamics and pharmacokinetics) of pre-hospital Ticagrelor in patients with STEMI according to two different analgesia protocols using Fentanyl or Morphine.

Acute Kidney Injury Genomics and Biomarkers in TAVR Study
Acute Kidney InjuryRenal Insufficiency6 moreIn the last decade, transcatheter aortic valve replacement (TAVR) has become an increasingly utilized alternative procedure for replacing a stenotic aortic valve. This study collects clinical information, DNA, blood and urine samples (throughout procedural hospitalization) in order to investigate the incidence of acute kidney injury (AKI) in patients undergoing TAVR and to identify key clinical and procedural predictors of AKI. This study seeks to identify blood and urine biomarkers that can be used for early detection of AKI around the time of the procedure. The study seeks to assess for novel genetic variants associated with development of AKI after TAVR. Finally the study seeks to assess for novel genetic variants and biomarkers that are associated with adverse cardiovascular events after TAVR and to further explore how these events may inter-relate with acute kidney injury.

Strengthening Transplantation Effects of Bone Marrow Mononuclear Cells With Atorvastatin in Myocardial...
Myocardial InfarctionStem Cell Transplantation3 moreThe benefit of current stem cell transplantation therapy for myocardial infarction is limited by low survival rate for stem cell. The purpose of this study is to test whether intensive Atorvastatin therapy can improve the outcome of patients with impaired left ventricle function after myocardial infarction who underwent intracoronary transfer of autologous bone marrow cells.

A Comparison of Prasugrel at PCI or Time of Diagnosis of Non-ST Elevation Myocardial Infarction...
Acute Coronary SyndromesThe purpose of this trial is to investigate the potential benefits/risks regarding pretreatment with prasugrel in non-ST-elevation myocardial infarction (NSTEMI) participants with elevated troponin scheduled for coronary angiography/percutaneous coronary intervention (PCI).

ST Segment Elevation Myocardial InfarctionThis is a single-centre, open-label prospective randomized pharmacodynamic investigation of 2 antiplatelet regimens in patients undergoing coronary intervention for ST segment elevation myocardial infarction(STEMI): Tirofiban bolus only or bolus followed by 2 hour infusion on top of 600 mg clopidogrel or 60 mg prasugrel. Prasugrel given at 60 mg.

Action of Amantadine on Post-Stroke Aphasic Patients
Cerebral InfarctionThe objective of the study is to test the action of the amantadine, as DOPA-agonist, in a double blind cross-over trial, amantadine / placebo, on the verbal fluency of chronic post stroke aphasic patients.
