Active clinical trials for "Myocardial Ischemia"

Study in Vietnamese Patients with Coronary Heart Disease to investigate safety and P2Y12 Receptor Inhibition Effects of Ticagrelor and Clopidogrel

Conventionally, long-axis in-plane (LA-IP), short-axis out-of-plane (SA-OOP) and dynamic needle tip positioning based on SA-OOP views are commonly used method to image the target vessel during cannulation under US guidance. A modified SA-OOP that add developing line on the ultrasonic probe improve the success rate of cannula insertion into the radial artery on the first attempt.

Вackground. Progressive atherosclerosis is accompanied by unfavorable clinical outcomes, study and understanding of this process, creation of risk assessment method is necessary for individualization of approaches to treatment and prevention of this condition. Purpose of the study. Creation of a mathematical model to assess the risk of accelerated atherosclerosis development, using methods of factor and correlation analysis. Patient Characteristics and Study Methods. A retrospective cohort study included 202 patients with coronary heart disease. Group 1 included patients who had had myocardial infarction or unstable angina, emergency arterial stenting, stroke, peripheral artery thrombosis, critical ischemia, and lower extremity amputation within 2 years before study inclusion. Patients in the comparison group did not have these events. The influence of each of the studied parameters on the probability of fast progressing atherosclerosis was determined by factor and correlation analysis. The prospective part of the study will include follow-up of patients from both groups for 12 months. Annual "endpoints": fatal outcome, unscheduled coronary revascularization, nonfatal myocardial infarction and stroke, hospitalization due to unstable angina pectoris, stent thrombosis, stenting/plasty of lower limb arteries.

Introduction. Ischemic cardiomyopathy is one of the death leading causes in industrialized countries. Up-to-date ESC guidelines recommend a surgical approach (coronary by pass graft) in patients with multivessel coronaropathy, with involvement of left main (LM) or proximal left anterior descending (LAD) artery. In any case, is recommended the use of the internal thoracic artery (ITA) as conduct of choice. In consideration of the very strong evidence supporting the use of ITA, the study objective is to analyze and compare some blood markers collected from ITA blood vs. LAD blood, with the purpose of better understanding the technique benefits from a biological point of view, being the hemodynamic one already evident. Methods. Forty patients scheduled for coronary bypass graft (CABG) surgery at the Cardiac Surgery Unit of European Hospital of Rome will be enrolled. Patients which intervention includes off-pump ITA-LAD anastomosis will be included. For each patient blood sample from ITA and LAD will be collected. On those samples, polymorphonuclear leukocytes and platelets activity, endothelial dysfunction, oxidative stress and inflammatory burden will be analysed. In patients in which a pre-operative coronary CT scan is available, findings will be correlated with atherosclerotic plaque morphology. Expected results. Diseased LAD's blood will have a deranged markers profile compared with ITA's, with augmented inflammatory burden, reduce NO availability and increased platelet activation. In the patients subgroup with available coronary CT scan will be possible to esteem the effective blood mixing and speculate on a possible pharmacological effect of CABG, in terms of dilution of inflammatory burden in the target vessel.

The aim of the retrospective study is to characterize the molecular mechanisms responsible for the effect of statins and evolocumab in patients with stable coronary artery disease. The research team will retrieve and review intravascular imaging and gene expression data previously collected in the catheterization laboratory during the following time-period: 8/1/2013-4/14/2015 and 5/4/2021 - 10/28/2022.

ORIGINS-RCE is an observational, cross-sectional, two-arm study aimed at determining if an individual's ethnic origin influences the number of blood vessel-forming stem cells in the bloodstream. Circulating progenitor cells will be enumerated and the distribution patterns of these cell types will be assessed to determine if these parameters differ between individuals of South Asian origin and European origin. Specifically, this study will evaluate if differential regenerative cell exhaustion (RCE) may account, at least in part, for the differences in cardiovascular risk reported between individuals of South Asian vs European origin.

This study aims to investigate the effect of the pneumatic tourniquet technique on the patients' hemodynamics; heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP).

The purpose of this study is to determine whether a Mediterranean Diet, personalized in terms of total calories, total lipids and balanced in terms of saturated, mono- and poly-unsaturated lipids, corrects the adverse fatty acid profile of patients with CHD and reduces markers of oxidative stress and inflammation more effectively than a low-fat dietary advice.

Coronary revascularization improves survival for patients with coronary artery disease. However,many patients are left with poor physical and mental health. Traditional cardiac rehabilitation involves moderate intensity continuous exercise (MICE). Alternatives to traditional cardiac rehabilitation programming may however provide superior understudied benefits to patients with poor physical and mental health. Nordic walking (NW) and high-intensity interval training (HIIT) are two examples of alternative programs for cardiac rehabilitation, which may provide superior physical and mental health benefits when compared to traditional MICE. The main purpose of this project is, therefore, to determine the short and long term physical and mental health benefits of alternative cardiac rehabilitation modalities, including NW and HIIT on exercise capacity, quality of life and depression after a 12-week program.

To evaluate whether nicorandil as an adjunctive therapy for acute myocardial infarction (AMI) reduces reperfusion injury.
