Scatter Radiation Exposure During Coronary Procedures - The Occupational SCAtter Radiation Registry
During diagnostic and interventional coronary procedures scatter radiation exposure is recorded with live-dosimeters at pre-specified anatomic regions of operators and sterile assistants. Scatter radiation data is correlated with detailed Xray exposure data and technical details of the procedure. The purpose of the registry is: to establish scatter radiation reference values …
COronary CoLLateralization in Type 2 diabEtic Patients With Chronic Total Occlusion
A severe coronary artery obstruction is a prerequisite for spontaneous collateral recruitment. The formation of coronary collateral circulation(CCC) is significantly impaired in type 2 diabetic patients with chronic total occlusion (CTO) compared with non-diabetic patients with CTO. This retrospective cohort enrolls consecutive T2DM patients who had at least one lesion …
Magnetic Resonance Imaging In Acute ST-Elevation Myocardial Infarction
Cardiovascular magnetic resonance imaging enables comprehensive assessment of cardiovascular function, morphology and pathology. The investigators aim to evaluate the nature and clinical significance of magnetic resonance imaging parameters in patients presenting with first acute ST-elevation myocardial infarction.
Clinical Study for the Investigation and Validation of a Therapy Procedure for the Adjustment of Risk Factors in Patients With Coronary Heart Disease by Means of Digital Therapy Control
This study will test a controlled investigation of the efficacy and effectiveness of iATROS digital therapy management for risk factor adjustment in patients with coronary heart disease (CHD).
Brain Imaging of Childhood Onset Psychiatric Disorders, Endocrine Disorders and Healthy Volunteers
Magnetic Resonance Imaging (MRI) unlike X-rays and CT-scans does not use radiation to create a picture. MRI use as the name implies, magnetism to create pictures with excellent anatomical resolution. Functional MRIs are diagnostic tests that allow doctors to not only view anatomy, but physiology and function. It is for …
Chronic Kidney Disease-related Sarcopenia With Poor Prognosis
Chronic kidney disease (CKD) has become a global public health priority over the past few decades, affecting 10-12% of the adult population and has received increasing attention. Sarcopenia describes a generalizes degenerative skeletal muscle disorder involving the loss of muscle mass, muscle function and/or physical performance. Indeed, Sarcopenia is a …
Early Perioperative Quality Of Recovery After Hip and Knee Arthroplasty: a Retrospective Comparative Cohort Study
Hip and knee replacements are indicated to improve long-term quality of life and pain. These long-term results may depend on the quality of the initial postoperative recovery. However, early postoperative health status after total hip arthroplasty (THA) and total knee arthroplasty (TKA) is not accurately described. Through this retrospective study, …
A Real World, Multi-centric, Observational Registry Study of Chronic Kidney Diseases
Chronic kidney disease (CKD) refers to a variety of different diseases characterized by impairment of kidney structure and/or renal function. The prevalence of CKD in China is as high as 10.8%. With a population of more than 150 million, China has the largest number of CKD patients all over the …
Clinical Results of Small Incision Lenticule Extraction (SMILE) for the Correction of High Myopia
Small Incision Lenticule Extraction (SMILE) was introduced in 2011 using the VISUMAX femtosecond laser (Carl Zeiss Meditec, Jena, Germany). It is designed for correction of myopia and myopic astigmatism. It involves the creation of a corneal tissue disk called lenticule and its extraction through a minimally invasive incision, utilizing only …
The Multicenter Cardiology Monitoring Platform Registry
The multicenter Cardiology Monitoring Platform registry (mCMP-registry) is a prospective observational registry including multi-omics (diagnostic) measurements performed as part of routine clinical care, bio-banking (optional), and yearly questionnaires (optional). It's objective is to optimize (early) diagnosis and risk-stratification of (early) cardiovascular diseases, specifically cardiomyopathy phenotypes, arrhythmias, and coronary artery disease, …
