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

Start date: October 30, 2020
Phase:
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: 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
Phase:
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).

NCT ID: NCT06008041 Active, not recruiting - Clinical trials for Coronary Artery Disease

Multimodal Epicardial and Endocardial COronary PHYsiological Evaluation in Pathological Situations (PHYCO)

PHYCO
Start date: July 13, 2023
Phase:
Study type: Observational

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.

NCT ID: NCT05937230 Active, not recruiting - Clinical trials for Coronary Heart Disease

Drug-coated Balloons and Drug-eluting Stents in Diabetic Patients

Start date: June 1, 2015
Phase:
Study type: Observational [Patient Registry]

Drug-eluting stents (DES) have long been recommended as the default device for patients undergoing percutaneous coronary intervention (PCI). Drug-Coated Balloon (DCB) angioplasty is similar to plain old balloon angioplasty procedurally, but there is an anti-proliferative medication paclitaxel-coated on the balloon. DCB angioplasty has the following advantages compared to DES implantation: Firstly, the drug in DCB is uniformly distributed and released, whereas the drug release of DES via the stent platform is uneven -85% of the vascular wall is not covered by the stent strut. Secondly, there is no alloy in the vessel after DCB angioplasty, while the coronary stent platform and polymer might cause temporal or persistent inflammatory response leading to intimal hyperplasia. Finally, there is no metal cage restraining vessel motion after DCB, and the physiological function of coronary arteries would be maintained. Currently, DCB constitutes an important treatment option in ISR, which is endorsed by the 2018 European Society of Cardiology Guidelines on myocardial revascularization. In addition, some interventional cardiologist has also applied DCB in de novo lesions in their clinical practice. Diabetes is associated with worse outcomes after coronary revascularization and has been identified as an independent predictor of adverse events in patients with cardiovascular disease. Although some small sample size RCTs and observational studies have suggested that the clinical prognosis of DCB is non-inferior to the drug-eluting stent (DES), there is still a lack of evidence comparing the DCB versus DES for de novo or ISR coronary lesions in diabetic patients. The current study aims to compare the long-term efficacy of DCB to DES in de novo or ISR coronary lesions in diabetic patients.
