Filter by:ST-elevation myocardial infarction (STEMI) is mostly caused by the rupture or the erosion of a vulnerable atherosclerotic plaque, initiating with intraluminal thrombosis and resulting in total occlusion of the coronary artery. Thrombus formation is a complex and dynamic process involving flow, blood cells and several plasma proteins, and it has not been clearly elucidated. To define - through proteomic approach - the composition of occluding thrombus and its time changes in patients with STEMI, trying to identify novel biomarkers of coronary thrombosis.
Overall Aim Coronary artery disease significantly contributes to morbidity and mortality in the United States. Atherosclerotic disease can lead to stenosis of the coronary arteries and subsequent cardiac hypoperfusion. Patients with a critical stenosis of the LAD, potentially leading to acute anterior wall myocardial infarction, may be asymptomatic at presentation with subtle EKG changes as its only manifestation. It is imperative for physicians to recognize patients with new T wave inversions in leads V2-V3 as the standard course of management may lead to poor prognosis. The purpose of this study is to determine if collateral circulation to the left anterior descending (LAD) artery will mask the presence of a Wellens sign and therefore diminish its diagnostic utility. The conclusion of this study would raise awareness for physicians in light of an absent Wellens sign. Hypothesis The presence of coronary collateral circulation to the LAD masks the presence of a Wellens sign (both Type 1 and Type 2) in precordial leads V2-V4.
Background: The six-minute walk test (6MWT) is widely used as an instrument for assessing the functional capacity of cardiac patients. It's a simple, low cost test that better reflects day-to-day activities when compared to other tests. Its use to evaluate the functional capacity of cardiac patients in the in-hospital phase after acute myocardial infarction requires further studies. Objective: To evaluate the safety of the 6MWT performed on the third day after acute myocardial infarction (AMI). Methods: It's a cross-sectional study, to be accomplished in Hospital São Paulo - Federal University of Sao Paulo. Individuals, of both genders, aged 18 years and over, will be assessed on the third day after acute myocardial infarction. The 6MWT will be performed according to the norms of the American Thoracic Society. The distance covered during the 6MWT will be measured as weel as adverse events.
Multicenter randomized double blind trial comparing intravenous cangrelor and oral ticagrelor in patients with acute myocardial infarction complicated by initial cardiogenic shock and treated with primary angioplasty.
Cardiovascular diseases (CVD) are the leading cause of mortality and morbidity worldwide. The most important aspect of CVD secondary prevention is adherence to guideline-indicated pharmacological therapy which globally remains low. In previous studies, a Polypill containing fixed dose combination of essential drugs have improved patient adherence to these drugs. The effect of such a strategy on pharmacological therapy uptake, cost-effectiveness, and CVD recurrence in our setting will be assessed in this study. Participants hospitalized in three referral hospitals in Isfahan, Iran because of an acute myocardial infarction (MI) (ST elevation MI (STEMI) or non-ST elevation MI (NSTEMI)) will be randomized to either receiving Polypill or usual care after MI. Patient recruitment will be carried out at the time of patient discharge from the hospitals.
Psychological processes play a complex role in the pathophysiology of many diseases. However, the body and emotional perception of patients and the relationship between dreams and disease still need to be investigated. The investigators planned an observational and controlled research aimed at assessing some previously unaddressed baseline psychological characteristics and their changes at 1 and 5 years after a short-term psychotherapy in carefully characterised patients with heart or oncologic diseases . The patients that will be enrolled are: - 50 patients ≤ 75 year old with acute myocardial infarction; - 30 patients ≤ 75 year old with Tako-Tsubo syndrome; - 50 women ≤ 75 year old, recently operated on breast cancer: - 90 control subjects of the same age and gender of the enrolled patients, without relevant pathologies during the last 10 years. Relevant pathologies are defined as those that required a hospitalisation or a long-lasting medical therapy. At the enrolment all the subjects will undergo a complete medical evaluation, and the following psychometric tests: Self-evaluation test, Social Support Questionnaire, Beck Depression Inventory II (BDI II), MacNew Heart Disease Health-Related Quality of Life Questionnaire, State-Trait Anxiety Inventory (STAI), State-Trait Anger Expression Inventory (STAXI 2). In two distinct following meetings, an open questionnaire exploring the body and emotional perception, and another exploring past and recent dreams, will be administered. The same evaluation will be done for the healthy subjects. After the initial evaluation, all the patients will be given the choice to start a short-term psychotherapy lasting 6 months on top of medical therapy or to continue classic medical therapy only. Healthy subjects will be not offered the possibility to follow psychotherapy. At first year of follow-up, the battery of psychometric test, and the two questionnaires exploring the body and emotional perception, and changes and characteristics of dreams during the psychotherapy, will be re-administered. The following data will be evaluated: Psychological characteristics at follow-up. Incidence of new relevant medical events Quality of life Relationship between psychological characteristics and health status, and quality of life At 5 year follow-up psychometric tests and the clinical data will be evaluated in all the groups.
The purpose of this study is to evaluate the safety and clinical efficacy of VM202RY injected via transendocardial route using C-Cathez® catheter (Celyad, S.A., Belgium) in subjects with AMI. - Stage 1: Evaluation of safety and tolerability of VM202RY injection - Stage 2: Evaluation of safety and efficacy of VM202RY injection
This study will compare clinical outcomes of immediate stent implantation with deferred stent implantation(4-10days after primary angiography) for patients presented with acute myocardial infarction due to left main coronary artery occlusion.
This study will compare the microcirculatory resistance (IMR) of infarct-related artery (IRA) in patients who underwent immediate versus deferred stenting during percutaneous coronary intervention (PCI) for acute myocardial infarction.
This is an observational diagnostic study that aims to evaluate the diagnostic value of circRNA-Uck2 in Acute Myocardial Infarction (AMI) in adults as compared to healthy and unstable angina controls. Rapid and adequate diagnosis of AMI is of great importance to enable a rapid start of treatment, save large tracts of dying myocardium, reduce the infarct size,and thereby decrease the risk of subsequent heart failure.
