NCT ID: NCT05693428 Completed - Clinical trials for CHD - Coronary Heart Disease

Influence of Anesthetics on Clinical Outcome During Cardiac Surgery in Adults

Start date: January 22, 2022
Phase: N/A
Study type: Interventional

Abstract Cardiac surgery in adults is associated with the occurrence of post-operative complications. Even minor complications can increase the cost of their treatment. Given the potentially preventable nature of a number of these postoperative complications, preventive methods should be used to improve outcomes after cardiac surgery. One of them, is the choice of anaesthetic technique. Objectives: To evaluate the effects of sevoflurane, isoflurane and propofol on blood oxygen transport function and body energy expenditure during cardiac surgery in adults. Materials and methods. A total of 90 patients were included in the study. All patients were divided into 3 groups: 1- (n=30) included patients who were anesthetized with propofol. The second group (n=30) consisted of patients who underwent sevoflurane inhalation anaesthesia. Group 3 (n=30) was treated with isoflurane. All patients underwent coronary artery bypass grafting under cardiopulmonary bypass.

NCT ID: NCT05661994 Completed - Clinical trials for Coronary Artery Disease

Omega-3 Supplementation on Serum Fetuin-A Levels

Start date: December 18, 2020
Phase: N/A
Study type: Interventional

Background and aims: One of the investigated possible modulators of serum fetuin-A, associated with the risk of developing coronary artery disease (CAD), is omega-3 fatty acids (FAs). This study aims to evaluate the effects of omega-3 FA supplementation on serum fetuin-A concentration in patients with CAD. Methods: The study was carried out on 34 male volunteer patients aged 35-75 years, newly diagnosed with CAD by conventional coronary angiography. Patients with CAD were divided into the "Omega-3 Group (n:16)" and "Control Group (n:18)". Low-fat diet principles were explained to both groups at baseline. While 1.560 mg/day omega-3 FA supplementation was given to the patients in the omega-3 group for eight weeks, but not in the control group. Food intake was recorded using six-day food records.

NCT ID: NCT05643586 Completed - Clinical trials for Coronary Artery Disease

Effects of Ticagrelor Versus Prasugrel on Coronary Microcirculation in Patients Undergoing Elective Percutaneous Coronary Intervention: Results of the PROtecting MICROcirculation During Coronary Angioplasty (PROMICRO)-3 Randomised Study

PROMICRO-3
Start date: December 1, 2017
Phase: Phase 4
Study type: Interventional

Besides being at least as effective as prasugrel in inhibiting platelet aggregation, ticagrelor has been shown to have additional properties potentially affecting coronary microcirculation. We sought to compare the effects of ticagrelor and prasugrel on absolute coronary blood flow (Q) and microvascular resistance (R) in patients with stable coronary artery disease (CAD) undergoing elective percutaneous coronary intervention (PCI). The PROMICRO-3 study shows that in patients with stable CAD undergoing PCI pre-treatment with a loading dose of ticagrelor compared with prasugrel improves post-procedural coronary flow and microvascular function and seems to reduce the related myocardial injury.

Start date: July 1, 2019
Phase:
Study type: Observational

A single center, prospective, observational study to investigate the impact of intravascular ultrasound (IVUS) on the functional percutaneous coronary intervention (PCI) result (assessed with fractional flow reserve (FFR)) and one-year target vessel failure (TVF) rate after percutaneous treatment of long coronary artery lesions

NCT ID: NCT05596279 Completed - Clinical trials for Coronary Artery Disease

PANOVISION: Feasibility and Safety of Hybrid IVUS-OCT System

Start date: November 20, 2019
Phase: N/A
Study type: Interventional

Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) were all recommended for percutaneous coronary intervention (PCI) optimization in the latest guidelines, however, which imaging modality was more suitable as either a diagnostic or guidance tool was still unknown. Recently, a novel, well-designed hybrid imaging system was approved for clinical use, allowing the accurate co-registration of two imaging modalities and immediate, simultaneous image review. For testing each modality in the hybrid imaging system, the investigators conducted this prospective, multicentre, non-inferiority trial. In this study, all participants achieved hybrid IVUS-OCT imaging after stenting, at meanwhile, patients randomly assigned to the IVUS arm were performed control IVUS (OptiCross, Boston Scientific, Natick, MA), and patients randomly assigned to the OCT arm were performed control OCT (C7 Dragonfly Duo, St. Jude Medical, St. Paul, MN). In this study, the investigators evaluated the non-inferiority of standalone IVUS versus control IVUS or standalone OCT versus control OCT in clinical feasibility using clear stent capture rate (CSCR) and safety using perioperative device-related adverse cardiovascular events.

NCT ID: NCT05562687 Completed - Hypertension Clinical Trials

Association Between Some Polymorphisms in Apelin/ Apelin Receptor Genes and Coronary Artery Disease in Syrian Patients

Start date: December 15, 2019
Phase:
Study type: Observational

The apelin-APJ signaling pathway has emerged as an important novel mediator of cardiovascular control and blood pressure homeostasis. Genetic variation in apelin and its receptors likely contributes to essential hypertension, in addition to a range of traditional risk factors. Thus, a study will be conducted on Syrian patients with hypertension and coronary artery disease to investigate some of the single polymorphisms in the apelin gene and its receptor that may be responsible for the development of these diseases, and to link the levels of this peptide and its receptor in the blood with these polymorphisms and the percentage of these diseases (as shown by many Modern Global Reference Studies).

NCT ID: NCT05550805 Completed - Clinical trials for Major Adverse Cardiovascular Events in Patients With Coronary Artery Disease

Prognostic Study of Major Adverse Cardiovascular Events in Patients With Coronary Artery Disease Based on Metabolomics, and Lipidomics

Start date: November 1, 2017
Phase:
Study type: Observational

To investigate whether there were differences in metabolomics and lipidomics in patients with coronary artery disease who had major adverse cardiovascular events during follow-up compared with those who did not.

NCT ID: NCT05541757 Completed - Clinical trials for Coronary Artery Disease

Rivaroxaban - Percutaneous Coronary Intervention

Start date: January 1, 2021
Phase:
Study type: Observational

We investigated in-vitro the management of intraprocedural anticoagulation in patients requiring immediate percutaneous coronary intervention(PCI) while using regular direct oral anticoagulants(DOACs). Twenty-five patients taking 20mg of rivaroxaban once daily comprised the study group, while five healthy volunteers included the control group. In study group, a beginning(24-hours after the last rivaroxaban dose) examination was performed. Then, the effects of basal and four different anticoagulant doses(50IU/kg unfractionated heparin(UFH), 100IU/kg UFH, 0.5mg/kg enoxaparin, and 1mg/kg enoxaparin) on coagulation parameters were investigated at the 4th and 12th hours following rivaroxaban intake. Anticoagulant activity was assessed mainly by anti-factor Xa(anti-Xa) levels.

Impact of CYP2C19 Genotype-guided Clopidogrel and Ticagrelor Treatment on Platelet Function Test and Metabolomics Profile

Start date: September 1, 2019
Phase: Phase 4
Study type: Interventional

Several studies have shown that pharmacodynamic (PD) response varies between patients treated with clopidogrel and that individuals with reduced response have an increased risk of recurrent ischemic events, particularly in patients undergoing percutaneous coronary intervention. This is due to several factors influencing the response to clopidogrel, including genetic variations of the cytochrome P450 (CYP) 2C19 enzyme. Loss of function (LOF) carriers of the CYP2C19 gene are associated with the decreased generation of the active metabolite clopidogrel and decreased platelet inhibition, which translates to an increased rate of adverse cardiovascular events, particularly in the setting of percutaneous coronary intervention (PCI). Thus, drug regulatory authorities have cautioned about the decreased efficacy of clopidogrel among individuals with CYP2C19 LOF carriers and suggested using alternative therapies to inhibit p2Y12. Ticagrelor is a new generation P2Y12 receptor inhibitor with greater efficacy for PD and reduced rates of ischemic events compared with clopidogrel and are not affected by the CYP2C19 LOF polymorphism. However, in clinical practice, the genotype-guided selection strategy for the oral P2Y12 inhibitor has been limited despite intensive research efforts. This is due to the interaction of cardiovascular risk factors and molecular and biochemical complications that lead to poor response to platelet inhibitor therapy, which impedes physicians' ability to prescribe a more effective and personalized antiplatelet therapy. Therefore, we must move away from traditional approaches and use integrated systems biology study designs and disciplines to bridge the gap between genotype, phenotype, disease manifestation and/or recurrence. Pharmacometabolomics is a rapidly developing field that takes advantage of a systems pharmacology approach to probe the molecular pathways involved in drug response variability to understand metabolic changes and identify novel biomarkers that can be used to predict response more comprehensively. Using profiles of changes in metabolites can help establish drug exposure fingerprints and clarify the determinants of drug response. This study aims to investigate the Impact of pharmacogenetics-guided clopidogrel and ticagrelor treatment on platelet function test and its association with metabolomics in Coronary Artery Disease (CAD) patients undergoing PCI in Malaysia
