NCT ID: NCT06454045 Active, not recruiting - Clinical trials for Coronary Artery Disease

Evaluation of Platelet Aggregability in Patients With Previous Acute Myocardial Infarction or Concomitant Lower Extremity Peripheral Artery Disease

Start date: May 13, 2024
Study type: Observational [Patient Registry]

After an episode of acute ischemic syndrome, patients with concomitant peripheral arterial disease have a worse short- and long-term prognosis compared to patients with isolated coronary disease, but the mechanisms responsible are poorly understood. In this population, the presence of high platelet aggregability despite the use of antiplatelet drugs is related to a greater risk of future complications, including heart attack and death from all causes. Thus, the main objective of the present project is to evaluate the role of platelet aggregability, analyzed by optical aggregometry using the AggRAM® equipment, in patients with a history of previous acute myocardial infarction with and without the presence of peripheral arterial disease. Among the secondary objectives, it is worth analyzing platelet aggregability, in both groups, using the Plateletworks® method. This is a case-control study, with groups differentiated by the presence or absence of peripheral arterial disease, matched by sex and age. It is expected that, in the end, relevant aspects related to platelet aggregation will be better characterized in this high cardiovascular risk population, with a likely impact on new therapeutic strategies that can positively influence the morbidity and mortality of these patients.

NCT ID: NCT06342609 Active, not recruiting - Clinical trials for Coronary Artery Disease

Effect of Colchicine on Progression of Known Coronary Atherosclerosis in Patients With Stable Coronary Artery Disease

Start date: March 15, 2023
Phase: Phase 4
Study type: Interventional

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.

NCT ID: NCT06281041 Active, not recruiting - Clinical trials for Coronary Artery Disease

Nationwide Cohort Study of Antiplatelet Agents as Primary Prevention

Start date: January 1, 2013
Study type: Observational

There is no specific recommendation regarding pharmacologic treatment as primary prevention for patients with intermediate coronary artery stenosis whose revascularization was deferred based on negative fractional flow reserve (FFR). Current nationwide cohort study conducted using Korean National Health Insurance Service database evaluated the safety and efficacy of antiplatelet therapy in patients with intermediate coronary artery stenosis with deferred revascularization based on negative FFR (FFR>0.80).

NCT ID: NCT06270693 Active, not recruiting - Clinical trials for Coronary Artery Disease

hsCRP & CH Indices in Patients With Coronary Artery Disease With and Without Apical Periodontitis

Start date: November 1, 2022
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT06242171 Active, not recruiting - Clinical trials for Coronary Artery Disease

Prognostic Indices of Atheromatosis Severity and Coronary Artery Bypass Surgery Outcomes for Patients With Coronary Artery Disease

Start date: October 30, 2020
Study type: Observational

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).

NCT ID: NCT06235424 Active, not recruiting - Clinical trials for Aortic Valve Disease

Del Nido Versus HTK Cardioplegia in Adult Aortic Valve Replacement

Start date: October 1, 2018
Phase: Phase 4
Study type: Interventional

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.

NCT ID: NCT06226948 Active, not recruiting - Clinical trials for Coronary Artery Disease

Using the Visualization for Lifestyle Change in Patients at Risk of Cardiovascular Diseases

Start date: May 6, 2024
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT06183294 Active, not recruiting - Clinical trials for Stable Angina, Unstable Angina, NSTEMI

Evaluation of a Novel Non-Invasive Automated Fractional Flow Reserve Software System in Patients With Coronary Artery Disease

Start date: August 22, 2023
Study type: Observational

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).
