Active clinical trials for "Myocardial Infarction"

To investigate drug-gene interactions on the incidence of non-fatal myocardial infarction and stroke for hypertensive patients.

To determine if selected circulating blood factors that reflect enhanced thrombogenesis are associated with an increased incidence of recurrent coronary events, including cardiac death or non-fatal myocardial infarction.

To investigate the composition and nature of weight loss and weight maintenance during the Look AHEAD trial. Also, to model changes in resting energy expenditure and changes in cardiac structure and function associated with weight loss.

To evaluate a series of thrombotic, inflammatory, and genetic markers for myocardial infarction among participants in the Women's Health Initiative Observational Study (WHI-OS).

To provide new scientific information regarding the role of physical activity in primary and secondary disease prevention, particularly coronary heart disease (CHD).

Obstructive sleep apnea (OSA) has been known as a risk factor for coronary artery disease, heart failure, cerebrovascular accident and atrial fibrillation. One study reported that patients with OSA have more atherosclerotic plaque burden in intravascular ultrasonography examination. Among patients who admitted with acute myocardial infarction (AMI), 65.7% (69 of 105) patients were diagnosed with OSA. Other long-term follow-up study revealed that 45.4% of patients (594 of 1311) who performed percutaneous coronary intervention (PCI) were diagnosed with OSA. Moreover, the OSA group was a significant independent predictor of major adverse cardiac and cerebrovascular events (MACCEs). Polysomnography (PSG) is the gold standard for the diagnosis of OSA. But, PSG is expensive, time-consuming and difficult to perform immediately. Recently, a portable device named WATCH-PAT (Itamar Ltd, Israel) was developed for the diagnosis of OSA. Validation study demonstrated a high correlation between WATCH-PAT and PSG in apnea-hypopnea index, lowest oxygen saturation and sleep time. This result suggested WATCH-PAT can be performed as an alternative or supportive device of PSG. WATCH-PAT. The portable device also can be useful to detect OSA in bus drivers who can be the reason for public traffic accidents. Moreover, WATCH-PAT can be applied to assess postoperative improvement of OSA. Although OSA is known as one of the risk factors for cardiovascular disease, there is a lack of evidence to recommend of the evaluation of sleep disorder in patient with coronary artery disease. Awareness and compliance for OSA are very low in both patients and cardiologists. Active diagnosis and treatment are definitely needed. Therefore, the primary endpoint of this study is to evaluate the prevalence of OSA in AMI patients who treated PCI. The secondary endpoint is to evaluate the 1-year incidence rate of MACCEs according to the presence or absence of OSA.

PEACE study retrospectively evaluate patients who suffered an out-hospital cardiac arrest (OHCA) and who underwent a coronary angiography, enrolled in the registry of the Province of Pavia (Italy), Ticino Region (Switzerland), Wien region (Austria) and Nicosia area (Cyprus) to comprehend the best timing for post-ROSC ECG acquisition in order to reduce the number of false positive and to select the best candidates for emergency coronary angiography.

The objective of this multicenter, retrospective, cross-sectional, chart review study is to compare outcomes (disability, complications and mortality) of patients with large vessel occlusion stroke presenting at late time window selected by either Non-Contrast CT (NCCT) only, advanced imaging with CTP (Computed Tomography Perfusion), MRI (Magnetic Resonance Imaging), or medical management. Boston Medical Center (BMC) will serve as the main data coordinating site. Fifteen additional sites will seek local IRB approval or ethics approval. The aggregated de-identified data will be analyzed comparing types of interventions and outcomes by type of imaging or medical management.

This study is a prospective, observational, cohort study aiming to compare point-of-care high-sensitive troponin I testing from different sample types with central laboratory (CL) HS cTnI plasma samples. A registry of all included patients and their troponin results (POC, CL and HS cTnT) will be made to compare these testing methods.

Left ventricular thrombus is a common complication subsequent to ST-segment elevation myocardial infarction (STEMI) that related to increased embolic events. This study aims to assess the efficacy and safety outcomes of Rivaroxaban on the prevention of post-STEMI left ventricular thrombus.
