Active clinical trials for "Myocardial Infarction"

This study requires the consecutive enrollment of 60 patients following the first event of acute myocardial infarction, evaluating B-Cell Activating Factor (BAFF) and methylglyoxal (MGO) levels in the acute setting (pre-reperfusion) and 3 months after reperfusion.

In this study we pretend to determine the molecular (miRNAs expression, angiogenic and inflammatory biomarkers) and microcirculatory (assessed by the innovative continuous intracoronary thermodilution technique) effects of PiCSO compared to a standard PCI control group in patients with high-risk anterior STEMI. Then, we aim to assess the efficacy of these molecular biomarkers as prognostic tools. Also, we will evaluate the impact of PiCSO on the coronary microcirculation beyond the acute phase in the follow-up six months after STEMI. Finally, we will assess PiCSO influence on Heart Failure (HF) clinical variables and patients' quality of life including a cost-effectiveness assessment in the mid-term follow-up one year after the STEMI event.

The benefits of cardiac rehabilitation include improving exercise tolerance and quality of life. However the attending rate of the patients with acute myocardial infarction was low according to the previous studies. This is a retrospective chart review study collecting the basic characteristics of the patients diagnosed with acute myocardial infarction of Wang-Fang Hospital (from Jan 1, 2012 to June 30, 2021). The aims of the studies are to investigate the related issues of cardiac rehabilitation including (1) attending rate (2) the efficacy of exercise training (3) the factors that limit the participation of the training programs.

The hypothesis of this study is that consciously sedated patients suffering from ST-elevation myocardial infarction can be rapidly and safely cooled to a state of therapeutic hypothermia (32 to 34 degrees C) using the LRS ThermoSuit System prior to percutaneous coronary intervention.

Early treatment of Myocardial Infarction patients with mineralocorticoid receptor antagonist with help reduces the incidence of cardiac remodeling and development into heart failure. Also studying aldosterone synthase (CYP11B2) and mineralocorticoid receptor (NR3C2) gene polymorphisms in Egyptian Myocardial Infarction patients will help tailor medication therapy and optimize therapeutic effects with the least adverse effects.

The goal of this clinical trial is to compare two types of exercise prescriptions in cardiac rehabilitation eligible older adults (60 years or older) with heart disease. The investigators found in a single site pilot trial (insert NCTxxx) that one exercise prescription was better and are now repeating this study in a larger population at two sites (Baystate Medical Center, Springfield MA and Henry Ford Health System, Detroit MI). The main questions the investigators aim to answer are: Compare two different exercise prescriptions in cardiac rehabilitation on exercise outcomes Graded exercise test +Target heart rate range prescription [GXT-THRR] Rating of perceived exertion (RPE) What is the role of psychological feedback on fitness outcomes during cardiac rehabilitation and physical activity outside of cardiac rehabilitation. What are the long-term clinical outcomes between the two exercise prescriptions Participants will be asked to: Complete surveys about physical activity, exercise anxiety, exercise efficacy, and fears about exercising Perform fitness measures (6-minute walk test, balance tests, stand to sit tests, a 400 meter walk, and handgrip strength) Attend at least 18 sessions of cardiac rehabilitation after they are randomized to their exercise prescription group Wear a heart rate monitor and a physical activity monitor per study protocol Participants will be randomized (flip of a coin) to either receive a graded exercise test and psychoeducational feedback or lifestyle education (nutrition for cardiac). The graded exercise test will be used to create a personalized exercise prescription with the target heart rate range calculated from the test and the lifestyle education group will use their ratings of perceived exertion for their exercise prescription.

The purpose of this observational study is to assess why thrombolytic treatment with tissue-plasminogen activator (t-PA) fails in patients with acute ST-segment elevation myocardial infarction (STEMI). The study will include 200 STEMI patients at the time of arrival at Oslo University Hospital Ullevål after receiving prehospital thrombolysis. A blood sample will be taken immediately for the study of factors related to coagulation, fibrinolysis and inflammation. Levels of the biomarkers will be compared between patients with successful and failed thrombolysis.

The study is completely digital. Men and women who recently had an MI will be invited through a written brochure that will be present in all Norwegian departments of cardiology. Post-MI patients can check the investigators web site (www.sefh.no) to determine whether they are eligible for the study. After consent and answering the baseline questionnaire, each participant will be randomized to either the intervention or control group. Control group: Standard surveillance after MI (no specific focus on sexual activity and functioning) Intervention group: Online sexual counselling including a short information film. In order to assess the generalizability of the results, we will compare the age, sex and MI treatment of the respondents with data on Norwegian MI-patients in general.

This is a single-center, prospective, observational controlled cohort study designed to describe the role of WNT/B-catenin signaling and adenosine system after an acute myocardial infarction, correlating it with clinical markers of fibrosis/remodeling (primary objective). The modulation of the aforementioned molecular patterns will also be evaluated in light of the type of P2Y12 inhibitor implemented (ticagrelor or prasugrel) to identify variations in response (secondary objective).
