Filter by:This is a prospective cohort study to evaluate the long-term effect and safety of Genoss drug-eluting stents (DES) in patients with coronary artery disease with high ischemic features.
Postoperative atrial fibrillation (POAF) is associated with increased mortality and morbidity in patients undergoing isolated coronary artery bypass grafting (CABG). It has been estimated that 5-40% of CABG patients experience POAF. Advanced age, P wave abnormalities, left atrial dilation, emergency surgery, low left ventricle ejection fraction, low glomerular filtration rate and chronic obstructive pulmonary disease have been reported in the etiology. Predicting which patients would experience POAF following CABG is important since it would allow physicians to apply more focused prophylactic measures. Lactate is the final product of anaerobic glycolysis. Serum lactate level are increased in case of inadequate oxygen delivery to tissues. The investigators aim to assess whether serum lactate levels measured early in the postoperative period could be used as a predictive marker of POAF in adults undergoing isolated CABG.
This study aims to evaluate the efficacy and safety of abluminal biodegradable polymer ultrathin sirolimus-eluting stent (Genoss stent) as compared with a durable-polymer everolimus-eluting stent (Xience stent) in patients with coronary artery disease.
Diseased left Anterior descending coronary artery (LAD) is one of the most challenging conditions in Bypass surgery. we investigate whether on-pump coronary artery bypass grafting (CABG) is more beneficial in those critical patients or off-pump surgery.
The study is designed as a retrospective, international, multi-center cohort study to evaluate Steelex® Sternum Set for sternum closure. The data from 2 clinics located in Germany and Spain participating in the "OPTICABG" as well as in the "PREMIVALVE" study will be used for assessment. Only patients receiving a complete or a partial sternotomy closed with Steelex® Sternum Set will be included in the analysis. "OPTICABG" patients were followed up 3 months after surgery and "PREMIVALVE" patients until 6 months after surgery. Adverse Events (AE) / Serious Adverse Events (SAE)(e.g. surgical site infection, sternum stability, stroke, myocardial infraction, death etc.) reported in both studies will be used for the STERCCAS analysis.
This study aims to investigate whether DCB angioplasty, compared to statin-based medical treatment alone, will lead to more reduction in plaque lipid burden as assessed by near infrared spectroscopy (NIRS) at 6-9 months following the index procedure.
The design of this study is generally divided into two parts: First, establish an isolated coronary arteritis cohort. Then, through the case-control study, the clinical characteristics of patients with isolated coronary arteritis and patients with coronary artery disease are compared and the preliminary screening criteria for patients are constructed. Then, through mass spectrometry flow cytometry and cytokine detection, the biomarkers related to immune inflammation related to the occurrence of coronary artery disease are discussed to provide clues for further exploring the pathogenesis; Subsequently, a prospective cohort study was conducted to compare the clinical characteristics and biomarkers of patients with or without adverse cardiovascular events by following up patients with coronary inflammation, and to explore the prognostic factors of patients with coronary inflammation.
Recently, a new device for measuring physiological lesion severity, the pressure microcatheter, was introduced. The pressure microcatheter provides similar information to the conventional measurement technique but differs as it is easily advanced on a customary coronary wire and simplifies pullback maneuvers. The pressure microcatheter has been shown to provide comparable FFR results to pressure wires. Insightful-FFR is an investigator-driven, multicenter, randomized, open-label and prospective trial of patients with stable coronary artery disease or stabilised non-ST elevation acute coronary syndrome (ACS) with epicardial stenosis considered for PCI aiming at comparing clinical outcomes between pressure microcatheter and pressure wire-guided strategies. The study hypothesis states that the use of a Pressure Microcatheter for clinical decision making would be non-inferior to pressure wire-based strategy After determining the presence of a coronary artery disease/ stabilized acute coronary syndrome, patients will be randomized to use a pressure microcatheter (investigational device) or a pressure wire (comparator) to guide and optimize percutaneous coronary intervention (PCI). Patients will be followed up in hospital at 12 months and yearly until five years.
Data from human autopsy studies have showed that thrombosis of a ruptured plaque with a large necrotic core, inflammatory cells and a thin fibrous cap, the so-called thin cap fibroatheroma (TCFA), represents the main mechanism for acute coronary syndrome (ACS). Optical coherence tomography (OCT) is an imaging technique that provides high-resolution, cross-sectional images of tissue in situ. The resolution of OCT (10 um) is appropriate for measuring a cap thickness less than65 μm, and even the plaque macrophage density. 68Ga-DOTA-(Tyr3)-octreotate/NaI3-octreotide(68Ga-DOTA-TATE/NOC) Positron Emission Tomography (PET)/Computed Tomography coronary angiography (CTCA), targeting the somatostatin receptor subtype-2 selectively expressed by M1 macrophages may show coronary inflammation. The SHORE protocol aims at evaluating the synergy between OCT and 68Ga-DOTA-TATE/NOC in predicting coronary plaque progression as assessed by CTCA
Coronary revascularization, such as heart bypass surgery (CABG) and percutaneous coronary intervention (PCI [inserting a stent to open up blood vessels]) improve survival for people with coronary artery disease. Yet, many patients suffer from poor physical and mental health after coronary revascularization. Traditional cardiac rehabilitation involving moderate-to-vigorous intensity continuous training (MICT) improves physical and mental health. However, alternative exercise programs, such as high-intensity interval training (HIIT) and Nordic walking may provide superior benefits. Nordic walking is like Nordic skiing but uses specifically designed poles for walking. Nordic walking involved core, upper and lower body muscles, resulting in greater energy expenditure while reducing loading stress at the knee. To date, HIIT used in cardiac rehabilitation settings has focused on lower body (e.g., leg cycling). The investigators are not aware of HIIT protocols that target both upper and lower body at the same time. An exercise program that combines HIIT and Nordic walking (HIIT-NoW) may offer an alternative time-efficient whole-body exercise to improve physical and mental health. This study will test if HIIT-NoW can be an alternative exercise option to improve physical and mental health in patients with coronary artery disease.
