Filter by:The main study objective is to prospectively determine the influence of sex-related risk factors and psychosocial variables on neuronal stress responses and myocardial perfusion in a population of 64 female and male individuals 50-75 years of age and free of cardiovascular disease.
This is a randomized double-blind, placebo-controlled, investigator-initiated trial that compares Colchicine 0.5mg/day with placebo, among patients with stable CAD. Subjects will be educated to maintain medication compliance with other prescribed medications.
Endodontic treatment is done in Patients with chronic pulp exposure in patients with Coronary Artery Disease and systemic inflammatory markers recorded before and and after treatment and compared with patients with Coronary Artery Disease without chronic pulp exposure.
Coronary artery disease is a multifactorial disease. Traditional risk factors, such as obesity, diabetes, hypertension, stimulate the onset of an inflammatory process in the prone vessel and perivascular adipose tissue, which has not yet been clarified and is still being investigated. Coronary artery bypass grafting is an effective treatment of coronary artery disease, which has been shown to prolong survival. Perioperative analysis of the myocardial metabolic profile helps to identify appropriate markers and metabolites associated with early myocardial damage. This, in turn, helps to improve risk stratification by better understanding the mechanisms of the disease processes, in order to prevent postoperative myocardial infarction and its associated complications. Such indicators, which are related to the diagnosis and severity of coronary artery disease, as well as the prognosis of coronary artery bypass grafting, have been separately studied before, in the peripheral blood of patients with coronary artery disease, in healthy vascular tissues, such as mammary artery, compared to atherosclerotic tissue from the coronary artery, as well as in the epicardial adipose tissue, intraoperatively. The aim of the proposed study is to investigate and evaluate metabolic factors and biomarkers preoperatively, intraoperatively and postoperatively, in patients undergoing coronary artery bypass grafting and their prognostic value regarding a) the severity of coronary artery disease (Gensini score, ejection fraction, acute coronary syndrome) and b) the outcome of surgery (indications of myocardial damage and / or infarction, low cardiac output syndrome and use of intraortic balloon pump, atrial fibrillation, 30-day mortality).
The goal of this clinical trial is to compare del Nido and Bretschneider-HTK (HTK) cardioplegia solutions in patients undergoing elective aortic valve replacement. The main question it aims to answer is: • Does the del Nido cardioplegia provide better cardioprotection and clinical outcomes than HTK cardioplegia? Participants will receive one of the investigated cardioplegia solutions according to the randomization. Researchers will compare both groups in terms of cardioprotection (described as levels of CK-MB and hsTnI), in-hospital clinical outcomes, biochemical changes in coronary sinus blood and one-year follow-up.
In the framework of PhD research, the investigators will present a visualization of estimation of CVDs risk and the possibility of monitoring blood glucose levels in real-time. Based on the results, the investigators will assess the association of these with lifestyle change. The findings highlight the need for sufficiently reliable and high-quality evaluations of visualizations, technologies or applications used in the family medicine.
This retrospective study will evaluate the coronary angiograms of approximately 100 patients who have undergone invasive angiography and fractional flow reserve (FFR). DICOM files of the angiograms will be analyzed on a secure computer within the cardiac catheterization laboratory using the AutocathFFR software to assess if invasive FFR measurements and automated computer analysis of FFR measurements correlate. AutocathFFR measurement per lesion will be compared to the gold standard, invasive FFR value, where an FFR ≤ 0.80 will be considered "positive", while an FFR > 0.8 will be considered "negative". The AutocathFFR value will be compared to the invasive FFR measurements. The sensitivity and specificity of the AutocathFFR will be calculated, as well as the AutocathFFR accuracy, positive predictive value and negative predictive value per lesion. Device success will be calculated as the ratio of completed versus initiated AutocathFFR index calculations. Usability of the AutocathFFR software will be evaluated using dedicated questionnaires to be completed by the user (cardiologists).
The goal of this clinical trail is to evaluate the effectiveness and accuracy of the CCTA image assisted triage software(DeepVessel® Cardisight, Keya Medical.) for the triage of patients with suspected coronary artery disease.
The purpose of this study is to assess the engagement and usefulness of Care4Today® Connect CAD-PAD digital platform in participants with coronary artery disease or peripheral artery disease (CAD or PAD).
When performing coronary angiography in a stable situation, the identification of an intermediate coronary lesion (between 50 and 70%) is common, and requires additional functional evaluation. The gold standard for this evaluation is Fractional Flow Reserve (FFR). FFR is a flow ratio transformed into a pressure ratio by simplification, neglecting some parameters, especially microcirculatory resistance. The aim of this study is to investigate hemodynamic and structural assessment induced in specific conditions, and their repercussion on functional assessment by FFR to implement the diagnostic approach and personalize it for each patient.
