Active clinical trials for "Myocardial Ischemia"

The purpose of this study is to test whether cardiac autonomic dysfunction predicts is a prognostic marker in type-2 diabetics with ischemic heart disease

Atherosclerotic coronary heart disease is a condition thought to involve low-grade inflammation. Several reports, clinical and epidemiological, have demonstrated that intake of fish oil may be beneficial in attenuating the inflammatory process. Still, however, there are lacking data in respect to whether differences in composition of various marine oils may influence the inflammatory status differently. The hypothesis of the current study is that extract from the antarctic krill (Euphausia superba) is better than traditional fish oils when compared head-to-head with balanced composition of omega 3 content on inflammatory status.

Construction of coronary heart disease cohort of more than 10000 patients in China. Investigation on current situation of secondary prevention of CHD will be carried out and the effect of physician training and patient education will be evaluated.

The purpose of the study is to determine whether the excretion of renal water- and salt-channels in the urine reflects the handling of water and salt in the kidneys, and whether the excretion can be used to monitor and/or predict the effects of treatment of certain heart or lung diseases.

The progressive aging of the general population cause increase in number of extensive and long surgeries in older patients. Age is a risk factor for perioperative myocardial ischemia and Postoperative Cognitive Dysfunction (POCD) The suggested study will deal with the above-mentioned complication in patients older then 65 years undergoing major non-cardiac surgeries. It has been shown that Isoflurane and sevoflurane may have a cardio-protective effect after cardiac surgery involving cardio-pulmonary bypass, and it was recommended that isoflurane should be used in these cases. A question was raised but haven't been answered yet, whether this cardio-protective effect exists also in non-cardiac major surgery. The aim of this study is to evaluate whether there is a difference in the occurrence of postoperative cognitive dysfunction and perioperative myocardial ischemia between total intravenous anesthesia using propofol and isoflurane based anesthesia.

Coronary artery disease (CAD) is a silent killer that may go undetected for years. It is the leading cause of death with no limitation to geographic boundaries accounting to about 16.7 million deaths world wide. Different studies have shown that South Asians populations are more prone to CAD where it is emerging as an epidemic. According to a study conducted in Karachi it is estimated that the overall prevalence of cardiovascular diseases in Pakistan is 26.9% with 23.7% in men and 30.0% in women. However tools for measuring CAD have not being adequately validated. This study is designed to develop screening tools and to determine test characteristics of Rose Questionnaire and Minnesota Coded ECG alone and in combination for diagnosis of CAD, using MPI as gold standard in Pakistan.

We sight to evaluate whether patients with coronary artery disease (CAD) have more epicardial fat than patients without CAD, which would suggest that epicardial fat may be more than an "innocent bystander" and be actively involved in the disease process. Its role as a modulator of vascular response and myocardial function could potentially lead to new areas of cardiac research. We also sight to evaluate whether epicardial fat from patients with CAD releases more adipokines than subcutaneous fat from these patients which could prompt studies into the differential regulation of adipokine secretion in this tissue. Thus for e.g., the use of thiazolidinediones (glitazones), statins, ARBs or other compounds that can specifically modulate adipokine secretion could be explored to determine their benefit in ameliorating the effects attributable to increased epicardial fat.

Percutaneous coronary intervention is currently one of the effective methods for the treatment of ACS. Unfortunately, the incidence of ISR is as high as 10%-20% at 3-6 months after PCI. So it is necessary to identify the potential risk factors to provide evidence for the prevention of ISR. Current research shows that anxiety and depression are related to the increased risk of major adverse cardiac events and mortality in patients with acute myocardial infarction. But there remains a relative paucity of evidence for the association between anxiety and depression and in-stent restenosis (ISR) .So a retrospective cohort study was conducted in the first hospital of Qinhuangdao in 2015-2020. The patients who underwent coronary angiography 1 year after PCI in our hospital from January 2015 to September 2020 were selected. Patients were divided into ISR and non-ISR groups depending on the follow-up coronary angiography results. Logistic regression model was utilized for analyzing the association of depression and anxiety with the in-stent restenosis (ISR) after PCI.

The investigators hypothesized that the CRP/troponin ratio measured in patients presenting to the ED with elevated troponin levels could differentiate between patients with cardiac ischemia and those who present due to a systemic inflammatory or infectious disease. The aim of the study was to determine the necessary CRP/troponin ratio required to rule out cardiac ischemia in a large ED population and determine its impact on long-term prognosis.

The purpose of this study is to investigate the efficacy and mechanism of Adipokines Cardiac Protection in Obese Patients With coronary artery disease (CAD).
