Active clinical trials for "Myocardial Infarction"

This is an open-label PET/CT (positron emission tomography/computed tomography) study to investigate the diagnostic performance of 68Ga-BNOTA-PRGD2 in evaluation of myocardial infarction. A single dose of nearly 111 MBq 68Ga-BNOTA-PRGD2 ( ≤ 40 µg BNOTA-PRGD2) will be intravenously injected into myocardial infarction patients. Visual and semiquantitative method will be used to assess the 68Ga-BNOTA-PRGD2 PET/CT cardiac images and compared to the 99mTc-MIBI SPECT myocardial perfusion images and the 18F-FDG metabolism images.

Overall, the investigators aim to recruit 150 subjects during their hospitalization for an acute coronary syndrome (ACS). At two weeks post-ACS, the investigators will assess levels of gratitude and optimism, draw blood for baseline levels of biomarkers, gather baseline information about health behaviors critical to cardiac health, and obtain baseline measures of symptoms and function. Finally, the investigators will repeat assessments of biomarkers, behavior, and function at 6 months to allow us to assess the impact of gratitude and optimism on these outcomes; the investigators will also have an objective measure of physical activity via accelerometer (step counter) at 6 months. Specific Aim #1: To prospectively assess the association between gratitude/optimism 2 weeks after ACS and improvement in biological markers of cardiac health at 6 months post-ACS. Hypothesis: Higher levels of gratitude/optimism at 2 weeks will be associated with greater reductions in levels of biomarkers associated with negative heart health between 2 weeks and 6 months. Specific Aim #2 (*primary aim*): To assess the association between gratitude/optimism 2 weeks after ACS and subsequent adherence to health behaviors known to improve post-ACS prognosis at 6 months. Hypothesis: Higher levels of gratitude/optimism at 2 weeks will be associated with greater amounts of physical activity (measured by accelerometer) at 6 months (primary study outcome measure), and greater improvements in self-reported adherence to health behaviors (activity, diet, and medication) between 2 weeks and 6 months. Specific Aim #3: To assess the association between gratitude/optimism at 2 weeks and non-elective cardiac rehospitalizations (and other clinical outcomes) at 6 months. Hypothesis: Higher levels of gratitude/optimism at 2 weeks will be associated with greater improvements in depression, health-related quality of life, function, cardiac symptoms, and possibly readmissions, between 2 weeks and 6 months.

The association between obesity and cardiovascular disease (CVD) has mostly been studied using broad endpoints or have focused on cause-specific mortality. The investigators aim to compare the effect of body mass index (BMI) on different types of initial presentation of CVD.

We designed this study to evaluate the effect of N-acetylcystein on biomarkers of platelet activation , cardiac necrosis and coronary reperfusion in patients undergoing percutaneous coronary intervention.

Large randomised trials have shown that cardiovascular medications prescribed to patients at high cardiovascular risk are effective in reducing the incidence of cardiovascular events. Their use is recommended in the United Kingdom and international guidelines (e.g. the National Institute of Clinical Excellence). However, these medications do not prevent cardiovascular events in all patients and there is now a body of research investigating the effects of cardiovascular medications on outcomes in myocardial infarction (MI), including clinical presentation, infarct size and post-MI mortality. However, the independent effects of cardiovascular drugs on post-MI all cause mortality are unclear, and there are limitations to many of the published studies in terms of their cardiovascular drug exposure data. This project utilizes prospectively collected data on cardiovascular drug use, and links to MI data from hospital and mortality records.

On a population of patients followed by an office-based cardiologist and treated with eplerenone, the objectives of the survey are: To describe the characteristics of the population treated. To describe the methods of use of eplerenone (posology, duration of treatment, medicinal combinations). To describe the follow-up methods of the treatment. To describe the possible interruptions of the treatment

The purpose of this study is to determine the feasibility of pharmacogenomics testing in a community pharmacy using clopidogrel as an example. The investigators hypothesize that this testing is feasible in this setting.

Cardiac rehabilitation is an individual adapted multidisciplinary intervention for people suffering from Heart Disease. It involves; Dietary counseling, Exercise training, Psychosocial support, Physician smoking cessation Patient education The purpose is quick and complete recovery and to reduce the chance of recurrence. In Denmark people admitted with Acute Cardiac Disease is referred to a course of hospital based cardiac rehabilitation at discharge. The Danish Municipal Reform of 2007 changed the responsibility of rehabilitation from the Regions, who runs the hospitals, to the municipalities. Shared care is in this setting that elements of treatment are completed different places in Health Care. The aim of this study is: to establish a shared care model for Cardiac rehabilitation following admission with Acute Coronary Syndrome and to compare this model to the existing hospital based cardiac rehabilitation after admission with Acute Coronary Syndrome. Primary outcome is participation in cardiac rehabilitation.

Evidence supporting use of bioabsorbable polymer drug eluting stents (BP-DES) is uncertain. Thus the investigators planned a meta-analysis to compare outcomes of BP-DES versus PP-DES in obstructive coronary artery disease.

Patients who developed an acute coronary syndrome despite dual antiplatelet therapy with aspirin and clopidogrel may benefit from a further dose of clopidogrel before a percutaneous coronary intervention. The aim of this study is to evaluate safety and effectiveness of clopidogrel reloading in patients on chronic clopidogrel therapy with acute coronary syndrome undergoing percutaneous coronary intervention.
