Active clinical trials for "Infarction"

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).

To evaluate the prognostic value of surem TRAF3IP2 levels in patients with acute myocardial infarction

The WHISH trial applies state-of-the science behavioral principles and currently available technologies to deliver a physical activity intervention without face-to-face contact to ~25,000 older U.S. women expected to consent. It includes the National Institute of Aging (NIA) Go4Life® Exercise & Physical Activity materials 3 and WHISH developed targeted materials based on Go4Life® to provide inspirational tips and recommendations about how to achieve nationally recommended levels of PA and overcome barriers to exercise, with a means for self-monitoring and setting personal goals. The intervention builds upon evidence-based behavioral science principles and intervention components that have proven to be effective in increasing PA in older women, with innovative adaptive approaches to tailoring the delivery to meet individual (personal) needs.

After a myocardial infarction (MI), patients discharged home in sinus rhythm may develop AF that is asymptomatic, undetected, and undertreated. Previous studies (CARISMA and ARREST) have demonstrate high rates of new-onset AF recorded on implantable loop recorder (ILR), although the routine implantation of ILRs post-MI remains costly and invasive. The external loop recorder may effectively identify patients with new-onset AF through a validated diagnostic algorithm and targeted monitoring during a high-risk period (immediately after hospital discharge). We will prospectively randomize patients to receive an external loop recorder or standard care, evaluating rates of new-onset AF developing within 30 days after MI.

This prospective observational cohort study, will investigate the platelet phenotype, platelet genetic composition, and role of platelets as effector cells in women and men with myocardial infarction (MINOCA or MI-CAD) and controls. This study, which will take place at NYU and Bellevue Medical Center, and participating external sites. May have concurrent enrollment with the HARP Main Imaging (NCT02914483). Additionally, a sex, group of age and race matched disease controls 'CATH-NOCA' composed of women and men with stable angina referred for cardiac catheterization, will be enrolled. Blood obtained during the initial catheterization and 2 months post-MI will be utilized for platelet testing.

ISACS ARCHIVES network is part of ISACS TC (NCT01218776) health care program. It is a collaborative network of research centers that support the rapid development of new scientific information and analytic tools. The ISACS ARCHIVES network assists health care providers, scientists, and policymakers seeking unbiased information about the outcomes, clinical effectiveness, safety, and appropriateness of health care items and services, particularly prescription medications and medical devices in acute coronary syndromes (ACS).

The project is focussed on evaluating the impact of using a female-specific threshold in the diagnosis of myocardial infarction. This female threshold is lower than the overall hs-cTn threshold currently in use. The investigators hypothesize that this change in process, applied at the hospital level, will lead to better assessment, treatment and outcomes of women presenting to the emergency department with chest pain that is cardiac in nature.
