Association Between Intraoperative Pulse Pressure Variation and Postoperative Lactate Clearance in Cardiac Surgery
This study aims to evaluate the relationship between intraoperative pulse pressure variation (PPV) and postoperative lactate clearance in adult patients undergoing elective cardiac surgery. Intraoperative PPV values will be recorded, and blood lactate levels will be measured at admission to the intensive care unit and at 6 and 12 hours …
Predicting Plaque Growth Using Blood Flow Stress Markers: A Proof-of-Concept Study
Coronary artery disease occurs when fatty deposits (plaques) build up inside the arteries that supply blood to the heart. Some plaques remain stable, while others continue to grow or become more likely to rupture, which can lead to a heart attack. Identifying plaques that are at higher risk of progression …
Comparison of the Amplatzer Amulet Versus LAmbre Device for Left Atrial Appendage Closure
Clinical investigation with CE-marked medical devices, multicenter, prospective, randomized and controlled. Patients with non-valvular atrial fibrillation at high embolic risk and with at least one high bleeding risk criterion according to the Munich consensus document will be randomized to left atrial appendage closure with either the Amplatzer Amulet™ or the …
Quantitative Myocardial Perfusion Imaging Assessment by SPECT/CT
Myocardial perfusion single-photon emission computed tomography (SPECT) is a well-established functional imaging technique for the assessment of coronary artery disease. Recent developments in cadmium-zinc-telluride (CZT) camera technology have enabled significant reductions in acquisition time while improving image quality. Positron emission tomography (PET) myocardial imaging remains the reference standard for the …
Dynamic Arterial Elastance for Prediction of Vasopressor Requirement After Anesthesia Induction in Elective On-Pump CABG
This study aims to determine whether dynamic arterial elastance (EaDyn), measured after anesthesia induction, can predict the need for vasopressor treatment in patients undergoing elective on-pump coronary artery bypass graft surgery. EaDyn will be calculated from pulse pressure variation and stroke volume variation. Hemodynamic measurements will be recorded before anesthesia …
Prospective Study Protocol for Multiparametric PCCT Assessment of Early Ventricular Outcomes After CABG
The goal of this observational study is to learn whether information about heart muscle tissue from preoperative photon-counting CT, a newer type of CT scan, can help predict heart recovery 3 months after coronary artery bypass surgery. The study will include adults aged 18 years or older with coronary artery …
Bright Light Exposure in Surgical Patients
Elucidate the influence of intense light therapy pretreatment in patients undergoing cardiac surgery. We hypothesize that intense light exposure is associated with the peripheral stabilization of Per2 in human buccal swabs and plasma samples before surgery and with a decrease of Troponin I levels after surgery. In addition, we hypothesize …
Heart Failure and Aortic Stenosis Transcriptome
This study is aimed to investigate the global transcriptome in order to determine the expression profile of messenger RNAs (mRNAs), as well as long noncoding- (lncRNAs) and micro noncoding-RNAs (miRNAs) in heart failure (HF) and in aortic stenosis (AS). The aim is to clarify their role in cardiac disease pathogenesis, …
The Role of Cardiac Mechanics, Biomarkers and Frailty in Aortic Stenosis
The role of cardiac mechanics, circulating biomarkers and frailty in predicting outcomes in patients with aortic stenosis after aortic valve replacement (SCRABLES -The 2-Parts Study) Part I: Observational study to characterize phenotypes, structural alterations and biomarkers profiles in a broad spectrum of patients with aortic stenosis and heart failure with …
Risk Evaluation by COronary Imaging and Artificial intelliGence Based fuNctIonal analyZing tEchniques - III
This is a single-center, prospective cohort study. This study is designed to accurately analyze coronary artery plaque characteristics and local hemodynamic parameters in patients diagnosed with chronic coronary syndrome (CCS) or non-ST-segment elevation acute coronary syndrome (NSTE-ACS), with marginal lesions or obstructive lesions in major coronary arteries by multimodality imaging …
