Active clinical trials for "Myocardial 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).

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.

The objective of this study is to evaluate the safety of antiplatelet (APA)therapy continuation in patients undergoing lumbar spine surgery (laminectomy, discectomy and foraminotomy), and to gather evidence-based data regarding postoperative outcomes potentially related to APA management.

Two large homocysteine-lowering B-vitamin intervention trials have been performed in Norway during the period 1998 to 2005, NORVIT and WENBIT. The main objective in these trials was to study the clinical effects of homocysteine-lowering therapy with folic acid and vitamin B12 in patients with established coronary artery disease. Follow-up was terminated for NORVIT on Marc 31st 2004 and for WENBIT October 5th 2005, and none of the two trials proved any protective effect of the B-vitamin intervention on cardiovascular outcomes. There is so far no data on possible long-term effects following years of such B-vitamin treatment. Thus, the main objective of the combinded NORVIT-WENBIT study will will be to evaluate the long-term effect of the B-vitamin intervention on incident life-style diseases including cardiovascular disease, diabetes, osteoporotic fractures and cancer. A secondary object will be the identification of risk phenotypes or genotypes, and if such risk associations are midified by the B-vitamin intervention

Heart attack remains a major cause of death in adult population worldwide and especially within Scotland. A large portion of the general population has an increased risk of suffering from a heart attack because of their genetic make-up, disease profile and lifestyle choices. Literature suggests that apart from these known risk factors, long-standing inflammation (reaction of tissues to infection or injury) elsewhere in the body may be responsible for heart attacks. It has been suggested that gum disease may be one such condition. If left untreated, gum disease may expose the entire body to a long-term inflammatory burden where inflammatory molecules can disseminate from the gums into the bloodstream and affect various body structures. This study explores the influence of gum disease on the risk of heart attack by comparing the gum health of participants who recently had a heart attack to the gum health of participants with no history of heart problems after accounting for other risk factors. Findings will provide critical information for the design of our forthcoming study to establish the effect of treatment of gum disease on the risk of heart attack, and its cost-effectiveness. Ultimately this research will tackle another risk factor for heart attacks and thus inform enhancement of public health prevention strategies.
