Filter by:The clinical trial is intended to evaluate the efficacy, safety and economic benefit of coronary lithotripsy compared to other additional procedures (cutting or super high pressure balloon angioplasty, ablative procedures) in lesion preparation and interventional treatment of severely calcified coronary stenoses.
Ischaemic heart disease (IHD) and degenerative brain disease are two major sources of death and disability affecting all countries. While the consequences of obstructive disease in major vessels supplying blood to both organs have been widely documented, less attention has been paid to disease processes affecting the microcirculation that may affect cardiac and cerebral function. Yet, over the last decade significant progress has been made in understanding the substrate of microvascular disease in both organs. In the heart, arteriolar thickening and capillary rarefaction that reduce the conductance of the microvasculature and its ability to vasodilate in response to increased myocardial oxygen demands constitute the leading cause of coronary microvascular dysfunction (CMD). In the brain, concentric hyaline thickening of deep penetrating small arteries (arteriolosclerosis) with associated fibrosis of the vessel wall constitutes the most frequent substrate for cerebral small vessel disease (CSVD). Of note, both CMD and CSVD share common risk factors, such as age, hypertension, and diabetes.3 These factors might have a common effect on the microvascular domain of cardiac and cerebral vascular beds. Although a potential link between both conditions has been hypothesized based on the similarities between pathological changes and risk factors, advance in knowledge exploring this has been hampered by lacking objective evidence of CMD and pathological brain changes indicative of CSVD in prior research studies. Thus, the relationship between CMD and CSVD is unknown. The main objective of this study was to analyse the relationship between cerebrovascular disease and CMD in patients with atherosclerotic coronary artery disease (CAD).
This study aims to determine the factors affecting exercise adherence in patients with coronary artery disease (CAD). For this purpose, the following measurement tools will be used respectively: (1) "Patient Information Form" including sociodemographic characteristics of the patients and medical information related to the disease, (2) the Exercise Adherence Rating Scale (EARS), (3) Exercise Self-Efficacy Scale (ESE) and, (4) Turkish-Health Literacy Survey Europe-Q12 (HLS-EU-19-12Q-TR). Statistical analyses will be carried out by descriptive statistics (number, percentage, mean, standard deviation, etc.), correlation analysis and regression analysis.
The goal of this multi-center observational clinical trial is to investigate the genetic risk factors of patients with premature CAD and none traditional CAD risk factors through a multi-omics approach. The main questions it aims to answer are: - Genetic risk factors & metabolic fingerprints of patients with premature CAD and none traditional CAD risk factors remain unknown. - How to optimize current primary prevention strategy for this rare CAD subgroup？
A prospective, open label, multi-center, single arm, observational study designed to evaluate the acute safety and device performance of the Sapphire 3 0.85, 1.0 and 1.25mm diameter coronary dilatation catheter in predilatation of Chronic Total Occlusion (CTO) lesions during percutaneous coronary intervention. One hundred seventy (170) subjects will be enrolled with a target of one hundred fifty-three (153) evaluable subjects by the angiographic core laboratory at up to 15 clinical sites with the Sapphire 3 0.85, 1.0 and 1.25mm diameter PTCA dilatation catheter to pre-dilate CTO lesions in coronary arteries during their index procedure. All subjects will be screened according to the protocol inclusion and exclusion criteria and will be followed through study completion, which is defined as 24-hours post-procedure or hospital discharge, whichever comes first.
The goal of this clinical trial is to learn if simulator-based training will improve interventional cardiology fellows' skills and will improve patient outcomes. The main questions it aims to answer are: - Does this training improve specific operative parameters recorded during initial coronary interventions performed as first operators under senior supervision? - Will major and minor procedural complications be reduced after simulator-based training? Interventional cardiology fellows in their first year of training will be randomized between standard master-apprentice training or simulator-based training before starting their cath lab period. They will be supervised during their cath lab period as first operators by senior interventional cardiologists. During their first 50 procedures performed as supervised first operator, specific procedural data will be collected.
To assess the efficacy and side-effects of re-infusion of unwashed shed blood during off-pump coronary artery surgery using a novel cardiotomy circuit.
The primary purpose of this clinical trial is to evaluate the safety and efficacy of the percutaneous left ventricular assist system versus intra-aortic balloon pump (IABP) for Circulatory Support during High-risk PCI.
To evaluate the association between time from PCI to cancer surgery and cardiovascular and oncologic outcomes in early-stage cancer patients, A retrospective, population-based cohort study was conducted using data from the Korean National Health Insurance Service (K-NHIS) database.
To investigate clinical characteristics and survival outcomes of patients with obstructive hypertrophic cardiomyopathy who underwent concomitant coronary artery bypass grafting during septal myectomy.
