Active clinical trials for "Infarction"

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).

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.

Introduction: Smoking is a major avoidable cause of ill-health and premature death. Treatments that help patients successfully quit smoking have an important effect on health and life expectancy. Varenicline is a medication that can help smokers successfully quit smoking. However, there are concerns that it may cause adverse effects, such as increase in the occurrence of depression, self-harm and suicide and cardiovascular disease. In this study the investigators aim to examine the effects of varenicline versus other smoking cessation pharmacotherapies on smoking cessation, health service use, all-cause and cause-specific mortality and physical and mental health conditions. Methods: In this project the investigators will investigate the effects of varenicline compared to nicotine replacement therapies on: (1) long-term smoking cessation and whether these effects differ by area level deprivation; and (2) the following clinically-important outcomes: rate of general practice and hospital attendance; all-cause mortality and death due to diseases of the respiratory system and cardiovascular disease; and a primary care diagnosis of respiratory illness, myocardial infarction or depression and anxiety. The study is based on a cohort of patients prescribed these smoking cessation medications from the Clinical Practice Research Datalink (CPRD). The investigators will use three methods to overcome confounding: multivariable adjusted Cox regression, propensity score matched Cox regression, and instrumental variable regression. The total expected sample size for analysis will be at least 180 000. Follow-up will end with the earliest of either an 'event' or censoring due to the end of registration or death. Ethics and dissemination: Ethics approval was not required for this study. This project has been approved by the CPRD's Independent Scientific Advisory Committee (ISAC). The investigators will disseminate the findings via publications in international peer-reviewed journals and presentations at international conferences.

This study investigates whether an individualized exercise program, including a personal trainer, can improve cardiovascular status quantified with ultrasound to assess coronary flow reserve and other non-invasive techniques. The subjects in the study will be divided into two groups; one group will have a personalized exercise- and nutrition program and the other group will have acess to a gym membership, but no personal trainer.

Acute Myocardial Infarction (MI) is still the leading cause of death in the western world. Early warning (chest pain) signs of an acute MI are often misinterpreted and disregarded. In average it takes between 2-3 hours from the beginning of the chest pain. The damage to the heart in these 2 hours is critical and often irreversible. Thus an early warning test or device is highly warranted. Corsens has developed a noninvasive device using several sensors applied to the chest and a detection system able to recognize the ischemic origin of chest pain. This clinical study is intended for evaluating the safety and efficacy of the Corsens technology while use for myocardial infarction detection

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

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

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 purpose of this study is to analyze the association between aspirin efficacy and general platelet reactivity in relation to microembolic signals (MES) during carotid endarterectomy (CEA).

The outcome of brain injury (physical or stroke) may be related to a brain electrical phenomenon known as Cortical Spreading Depression (CSD). This is a brief cessation of function in a local region of brain tissue. It has been hypothesized that CSD may occur after brain injury and may expand the damage to adjacent brain areas. Our aim is to detect CSD by means of intracranial electrodes in patients with brain injuries and asses how these events alter the outcome of the patients.
