Active clinical trials for "Myocardial Ischemia"

This multicenter study involved 5 hospitals (Changhai Hospital; Yueyang Hospital of Shanghai University of Traditional Chinese Medicine; Gongli Hospital; Putuo Hospital of Shanghai University of Traditional Chinese Medicine; No. 904 Hospital of the PLA Joint Logistics Support Force Wuxi). The study enrolled 5000 consecutive patients without known CAD who underwent first coronary angiography for stable chest pain and carotid ultrasound was performed during hospitalization from January 2017 through December 2018.

The objective of this study is a comparative evaluation of Orsiro stent and of Resolute Integrity stent in terms of the extent of neointima formation at 4 months after implantation using optical coherence tomography (OCT).

The objective of this study is to evaluate angiographic confirmation of placement of any guidewire beyond the CTO, in the true vessel lumen, in patients undergoing CTO percutaneous coronary intervention (PCI) in which at least one Teleflex guidewire and at least one Turnpike catheter are used.

There is a clear need to develop improved tools to stratify risk in patients who seek emergency care for chest pain, one of the most common and potentially deadliest conditions encountered in acute care settings. The ECG has been the mainstay of initial evaluation of chest pain patients, yet is currently only diagnostic for a small subset of patients with ST-elevation myocardial infarction. Prior studies have identified candidate markers of ECG characteristics and preliminary algorithms that can identify patients with non-ST elevation myocardial infarction as well as those with very low risk of coronary artery disease. This study will enroll a cohort of consecutive chest pain patients needed to confirm the accuracy of these ECG markers and determine their maximal clinical utility as part of a risk stratification tool. With these improved tools, emergency providers (physicians, nurses, and paramedics) will be able to streamline the care provided to these patients beyond the costly and time-consuming overnight observation for serial cardiac enzymes and provocative testing.

This study aims to validate the sensor data of gyroscope and accelerometer in detection of hemodynamically significant CAD.

This study is a prospective, multicenter, randomized, blind, parallel and superiority test study. It is planned to select 206 cases of subjects with small coronary artery vessel disease who meet the inclusion/exclusion criteria. They are randomly divide them into Biolimus release coronary balloon catheter treatment group and plain old balloon angioplasty catheter (Powerline) treatment group according to the ratio of 1:1. All subjects accept clinical follow-up after operation, at 30 days, 6 months, 9 months and 12 months after operation. Follow-up with angiography is conducted at 9 months. The late lumen loss in diseased segment at 9 months after operation is the primary endpoint.

The purpose of this study is to evaluate respiratory parameters and functional capacity in coronary artery patients.

This multicenter study involved 5 hospitals (Changhai Hospital; Yueyang Hospital of Shanghai University of Traditional Chinese Medicine; Gongli Hospital; Putuo Hospital of Shanghai University of Traditional Chinese Medicine; No. 904 Hospital of the PLA Joint Logistics Support Force Wuxi). The study enrolled 5000 patients for suspected CAD who referred to coronary angiography from January 2017 through December 2018.

Noninvasive pressure-strain loop (PSL) derived myocardial work (MW) are more sensitive than conventional echocardiographic parameters in quantitative assessment of early myocardial dysfunction. The aim of this study was to assess left ventricular (LV) myocardial function in symptomatic patients with coronary artery disease using the promising method. Methods: Transthoracic echocardiography was performed on patients with angina or equivalent symptoms before coronary angiography. Images were stored and imported into the software for further offline analysis of PSL-based MW. MW analysis were carried out on each patient for global and regional myocardial function assessment.

At least 25 volunteers with a diagnosis of coronary artery disease in the Department of Cardiology of Dokuz Eylul University and who meet the criteria for follow-up and inclusion will participate in the study. Demographic and clinical information of the participants will be questioned. Active video games and exercise sessions will be randomized to last 25 minutes. Before and after the sessions, heart rate, blood pressure, shortness of breath, oxygen saturation and arterial stiffness will be measured. In addition, energy expenditure, heart rate, perceived exertion, shortness of breath and oxygen saturation will be recorded during the sessions. At the end of the sessions, the person will be asked if they enjoy active video games.
