Filter by: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.
In anesthesia, monitoring of core body temperature is one of important factors. Measurement of temperature using a pulmonary artery catheter is representative one of core temperature measurements. The core temperature by a pulmonary artery catheter is compared with the tracheal temperature by an endotracheal tube with thermometer. This study was designed to confirm the accuracy of the endotracheal tube thermometer.
To determine the effect of exercise training on cardiac outcomes in coronary artery disease patients after Stenting. There is a need to develop strategies, not only to prevent restenosis but also to improve patients' functional status and perception of well-being. In particular, it is not well defined whether exercise training can reduce the restenosis rate and improve the outcome after PCI.
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.
Today, continuous monitoring of vital signs remains a challenge since it generally requires the patient to be connected to multiple wired sensors, which restricts patient mobility in the intra-mural setting and complicates home monitoring in the extra-mural setting. Wearable devices on the wrist, although emerging, are often not clinically validated or limited to the monitoring of one or two vital signs. This study aims to validate the Corsano CardioWatch 287-2 for the continuous monitoring of heart rate at ≤ 4 bpm root mean squared error (RMSE); interbeat intervals at ≤ 50 ms RMSE; breathing rate at ≤ 2 brpm RMSE; and peripheral oxygen saturation at ≤ 3 percentage point RMSE. Also, this study aims to validate the Corsano CardioWatch 287-2 for the measurement of non-invasive blood pressure according to ISO 81060-2:2018.
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).
In coronary artery bypass grafting (CABG), the use of radial artery (RA) is recommended by the guidelines only to significantly stenosed vessel, due to its high vulnerability to competitive flow. Fractional flow reserve (FFR) is the gold standard to measure physiological significance of coronary lesions and the potential for competitive flow. This study aims to investigate whether the preoperative quantitative flow ratio (QFR) measurement, a novel coronary angiography-based FFR, is associated with RA graft failure post-CABG, and to explore the best cut-off value of QFR for RA grafts using. Patients from ASRAB-pilot trial (NCT04310995) undergoing primary isolated CABG using RA grafts, and with preoperative coronary angiography (CAG) images available for QFR analysis will be enrolled in this prospective double-blind observational study. QFR analysis will be conducted for all RA-grafted vessels based on preoperative CAG. The primary outcome will RA graft failure (FitzGibbon Grade B,O or S) evaluated by coronary computer tomography angiography or CAG at 7 days and 6 months post-CABG.
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.
This Post-market clinical follow-up (PMCF) study is designed as retrospective, multi-center study to collect real-life data. A multi-center design is used to ensure a representative sample of the physicians who have performed the procedure and to provide a reasonable enrolment period for the required data to be collected. The rationale of this study is to confirm and support the clinical safety and performance of any of these products in a real-word population of 200 patients who underwent an endovascular intervention within standard-of-care (SOC) where at least 1 of the products (named above) from Cordis US Corp were used.
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.
