This study is intended to provide contemporary data on the residual cardiovascular risk in all consecutive patients with acute myocardial infarction, especially in patients who survived stably within one-year after percutaneous coronary intervention. In addition, this study will identify which baseline clinical, angiographic, or treatment factors are associated with residual cardiovascular risk and bleeding events
The purpose of this trial is to evaluate the efficacy of a pericardial adipose graft transposition (Adipose Graft Trasposition Procedure, AGTP) for the improvement of cardiac function in patients with a chronic myocardial infarction. Preclinical studies in the porcine model of myocardial infarction have shown that the AGTP reduces infarct area and improves cardiac function. A first-in-man clinical (NCT01473433) trial showed that the AGTP is safe in patients.
To compare early and late clinical outcomes with everolimus-eluting cobalt-chromium stent in patients with ST-elevation acute myocardial infarction, as well as identify the characteristics and efficacy of CoCr-EES. Also, OCT sub-analysis will be conducted
Along with symptoms of chest pain, the presence of ST segment elevations on ECG is the criterion usually used in practice to identify patients with acute coronary artery occlusion and is essential for the direct and acute referral of patients for primary PCI. However, ECG does not always reflect changes in the posterior wall of the heart, often equivalent to the left circumflex coronary artery's (LCX) supply area, resulting in an underrepresentation of LCX as culprit artery in STEMI populations. There is a general concern that some patients with genuine acute occlusion of LCX may present without ST segment elevation and be denied reperfusion therapy, resulting in larger infarction and worse outcome. The aim of this trial is to implement record of posterior ECG leads (V7, V8 and V9) in addition to the standard 12-lead ECG in the pre-hospital setting and to evaluate the clinical impact of this implementation: In comparison to a control cohort of STEMI patients diagnosed with a pre-hospital standard 12-lead ECG prior study start, the investigators hypothesize that introducing V7-V9 leads as a clinical routine in the pre-hospital setting will identify patients with STEMI involving LCX and with a non-diagnostic standard 12-lead ECG.
The number of patients with cardiovascular implantable electronic devices (CIED), including ventricular pacemakers, continues to increase. However, there are no accurate electrocardiographic (ECG) criteria to diagnose acute myocardial infarction (AMI), even if due to acute coronary occlusion (ACO), with a ventricular pacemaker in situ. In this retrospective, multicenter, case-control study the investigators will examine ECG criteria to diagnose ACO in patients with ventricular paced rhythms. During this process, the investigators will also create a database from which investigators will be able to answer multiple additional questions on this population of patients.
ONASSIST is a registry of coronary ill patients who have had a functional test measuring anti-platelet effect and/or a genetic profile of response to anti-platelet drugs.
Coronary arterial bypass graft surgery (CABG) is proven safe with improved survival and greater quality of life in patients with coronary arterial disease. Evidences on the cardiovascular and gas-exchanges responses during and right after early exercise-based rehabilitation of this patients are limited. Objective: The investigators aim to analyse breath-by-breath cardiopulmonary and metabolic responses during six-minute walk test (6MWT) and shuttle walk test (SWT) in patients with or without left ventricular dysfunction (LVD) after CABG. In addition, the investigators will investigate oxygen consumption and cardiopulmonary responses during the early exercise-based rehabilitation in the first days after surgery. Methods: According to the left ventricular ejection fraction (LVEF), subjects will be allocated into two groups: with LVD (LVEF < 45%) and without LVD (LVEF > 45%). Patients will be submitted to the 6MWT and SWT linked to portable spirometric-telemetric device before and 6 days after CABG. During the first days after surgery, patients will be evaluated about pulmonary function and respiratory strenght at rest and oxygen consumption during the portable cycle ergometer protocol. Clinical outcomes as time to hospital discharge, pulmonary complications and occurence of arrythmias will be assessed during inpatient time until hospital discharge. Incidence of mortality, hospital readmission and angina recurrence will be evaluated in a one-year follow up.
The purpose of this study is to explore the pathogenesis of cognitive impairment after acute cerebral infarction by applying the multimodal function MRI to dynamically observe the changes of the value of NAA,Cho,Cr,FA in a certain region in the brain and the function of the brain ,and to provide a visual instrument for evaluating the therapeutical effects of Chinese medicine through the application of multimodal function MRI to observe the changes of the neurotransmitter in certain area in the brain before and after the treatment.
Aim of the study is to examine the effects of glycoprotein IIb/IIIa inhibitors on reperfusion success assessed by cardiac magnetic resonance imaging in patients with myocardial infarction and angiographic evidence of no-reflow.
