Active clinical trials for "Infarction"

The purpose of the study is to investigate the clinical outcomes, safety and cost-effectiveness of intravascular OCT imaging in patients with acute myocardial infarction undergoing percutaneous coronary intervention (PCI). About 4500 patients with acute myocardial infarction (estimated 1500 with OCT guidance and 3000 without OCT guidance during PCI）will be prospectively enrolled in 20 sites in China. The total duration of the study is expected to be 5 years, 2 years for enrolment and 3 years for follow up.

The objectives of this study are To establish a prospective registry of the whole patients who received percutaneous coronary intervention with Resolute Onyx™ stent. To evaluate the long-term efficacy and safety of coronary stenting with the Resolute Onyx™ stent. To compare the long-term efficacy and safety of coronary stenting between the Resolute Onyx™ stent and other contemporary drug-eluting stents which had established their own registry.

Although clinical data demonstrate advantages of combining complete revascularization with optimal cardiac rehabilitation (CR) less than one-third of patients in European countries participate in cardiac rehabilitation programs. Therefore, in cooperation with Polish leaders in cardiovascular medicine, rehabilitation and medical software design we aim to introduce and evaluate the system of optimal cardiac telerehabilitation in addition to optimal treatment of coronary artery disease.

This study aims to determine whether combination with regulatory T cell (Treg) levels and cardiac magnetic resonance imaging (CMR) are predictive of the severity of reperfusion injury following myocardial infarction and the prognosis in STEMI patients receiving primary percutaneous coronary intervention (PPCI).

all patient presented with ST elevated myocardial infarction and underwent PPCI will be calculated with CHA2DS2-VASC score and contrast volume / creatinine clearance as apredictive value for Contrast induced nephropathy and the predictive value of these scores will be compared with the approved predictive value of MEHRAN score which is also will be calculated to every patient .

Acute non-traumatic chest pain is a common kind of symptom in extremely critical condition, with various pathogenesis and different level of risk . Chest pain in high risk takes 1/3 of that. It mainly includes acute coronary syndrome (including myocardial infarction and unstable angina pectoris, accounted for over 95% of chest pain in high risk), aortic dissection, pulmonary embolism etc, and is in high lethality and deformity. The investigators do the research : To study the diagnosis and management condition of acute chest pain in extremely critical condition for last ten or more years in Qilu Hospital,Shandong University. To discuss the significance of key accompanying symptoms(for example radiating pain, chest distress, sweating, nausea etc), physical signs and lab examination in early diagnosis and risk stratification of acute chest pain in extremely critical condition. To study the effect factors of thrombus burden in STEMI patients, at the same time, creat a a simple, practical and scientific method of blood clots classification.

To find new biomarkers through Metabonomics Study of different types of myocardial infarction in Different Time.

To assess the platelet indices in patients undergoing primary percutaneous coronary intervention and its relation to the severity of coronary artery disease and short term clinical outcomes

The purpose of this study is to develop and implement a critical pathway to identify patients with ischemic cardiomyopathy who are candidates for an implantable cardioverter-defibrillator (ICD). This study will also determine whether the use of the critical pathway for ICDs is associated with a change in the ICD referral and implantation rate.

The investigators prospectively determined the impact on median door-to-balloon time of a protocol mandating (1) emergency department physician activation of the catheterization lab and (2) immediate transfer of the patient to an immediately available catheterization lab by an in-house transfer team consisting of an emergency department nurse, a critical care unit nurse, and a chest pain unit nurse.
