PUMCH Study Into Individualized Scanning for Coronary Artery Disease

COE
Start date: January 1, 2023
Phase:
Study type: Observational

Cardiac computed tomographic angiography (CCTA) is a non-invasive diagnostic imaging technique for visualization of the coronary arteries and thus, frequently used in the evaluation of coronary artery disease (CAD). CT technology is improving continuously, and various technological advances not only increase diagnostic accuracy, but also provide a substantial reduction in radiation dose and scan acquisition time. These modifications challenge optimal synchronization and timing of scan protocols in CM administration due to a shorter data acquisition window, hereby creating opportunities for injection strategies with a decrease in total amount of contrast media (CM). [4-6] Reducing the radiation dose of CT angiography and injected CM dose have become a routine need and trend in clinical practice. In addition to this, physical factors such as cardiac output and body weight are considered important factors with regard to variability in vascular enhancement. A standard 'one size fits all' protocol with a standard injected CM volume, independent of weight and length of the patient has proven to be outdated and precision medicine in the future should be based on individually tailored scan and CM injection protocols that are more scientific and involve various parameters such as individual tube voltage, patients weight and heart rate to benefit patients by reducing radiation exposure and CM dose while fulfilling the diagnostic purpose. Prospective studies focused on modifying both scan and injection parameters were completed in the Dutch (representing European) patient population with body weight varying between 40 and 130kg by Maastricht University Medical Center (MUMC) and have shown very promising results in Dutch population. In theory, these scan and injection protocols should be applicable to both average Dutch population (e.g. European population) and other heterogeneous patient populations, i.e. world-wide patient populations with any BMI category. However, so far, the effectiveness of this approach has not been deliberately discussed in the (on average) heavier North American population or the lighter Asian population. So, prior to promotion of the individually tailored CT scan protocols for global use, we need to obtain enough evidence in terms of the diagnostic confidence from those protocols in Chinese patients who could represent Asian population.

Angiography-derived FFR GPS in Predicting Post-PCI Physiological and Clinical Outcomes

Angio-GPS
Start date: January 1, 2017
Phase:
Study type: Observational

To investigate the feasibility of physiological map generated from angiography-derived fractional flow reserve (FFR) (angio-FFR) pullback and its value in predicting physiological and clinical outcomes after stenting.

NCT ID: NCT05492084 Completed - Clinical trials for Atherosclerosis, Coronary

Personalized Risk of Rapidly Progressive Atherosclerosis

RPA
Start date: January 1, 2019
Phase:
Study type: Observational

Š’ackground. Progressive atherosclerosis is accompanied by unfavorable clinical outcomes, study and understanding of this process, creation of risk assessment method is necessary for individualization of approaches to treatment and prevention of this condition. Purpose of the study. Creation of a mathematical model to assess the risk of accelerated atherosclerosis development, using methods of factor and correlation analysis. Patient Characteristics and Study Methods. A retrospective cohort study included 202 patients with coronary heart disease. Group 1 included patients who had had myocardial infarction or unstable angina, emergency arterial stenting, stroke, peripheral artery thrombosis, critical ischemia, and lower extremity amputation within 2 years before study inclusion. Patients in the comparison group did not have these events. The influence of each of the studied parameters on the probability of fast progressing atherosclerosis was determined by factor and correlation analysis. The prospective part of the study will include follow-up of patients from both groups for 12 months. Annual "endpoints": fatal outcome, unscheduled coronary revascularization, nonfatal myocardial infarction and stroke, hospitalization due to unstable angina pectoris, stent thrombosis, stenting/plasty of lower limb arteries.

NCT ID: NCT05489016 Recruiting - Clinical trials for Coronary Heart Disease

HuoXin Pills Intervention on Patients With Coronary Heart Disease After Drug-Coated Balloon Implantation

Start date: August 5, 2022
Phase: Phase 4
Study type: Interventional

This trial is a multi-center, randomized, double-blind, placebo, parallel controlled study. Objectively evaluates the curative effect of Huoxin Pills (concentrated pills) intervention on improving the prognosis of patients with coronary heart disease after drug-coated balloon implantation from a functional point of view. Huoxin Pill(concentrated pills), a traditional Chinese medicine, has been prescribed widely in the treatment of coronary heart disease, angina pectoris, and other diseases.440 patients were selected and followed up for one year. The quantitative blood flow score of the target vessel, late lumen loss, MACE incidence, and safety index were observed at 12 months.

NCT ID: NCT05472805 Completed - Clinical trials for Chronic Kidney Diseases

Neutrophil-Lymphocyte Ratio and Platelet-Lymphocyte Ratio to Predict Carotid Intima-Media Thickness in Chronic Kidney Disease Patients

Start date: January 1, 2022
Phase:
Study type: Observational

This study aims to determine whether the neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) can be used as predictors of coronary heart disease (CHD) in CKD patients undergoing dialysis at Moewardi General Hospital Surakarta. It was hypothesized that NLR and PLR, which have been identified as inflammatory biomarkers, would be significantly related to increased arotid intima-media thickness (CIMT) in CKD patients undergoing dialysis. This study is an observational analytic study using a cross-sectional approach conducted at department of renal-hypertension and hemodialysis unit in Moewardi General Hospital in Surakarta, Indonesia from January to July 2022.

NCT ID: NCT05471739 Recruiting - Clinical trials for Ischemic Heart Disease

Simultaneous Assessment of Coronary Microvascular Dysfunction and Ischemia With Non-obstructed Coronary Arteries With Intracoronary Electrocardiogram and Intracoronary Doppler

Start date: July 21, 2022
Phase:
Study type: Observational

Coronary Microvascular Dysfunction has been consistently shown to play a considerable role in pathophysiology of Ischaemia with non-obstructed coronary arteries (INOCA). While the both diagnoses are individually related to remarkably worse outcome, there is no available method to simultaneously determine INOCA-CMD endotypes in vessel level, during the invasive diagnosis. The investigators hereby hypothesize that, combined intracoronary electrocardiogram (IC-ECG) (considering the high sensitivity and specificity of IC-ECG for studied vessel-territory) and intracoronary doppler can simultaneously and successfully identify vessel specific coronary microvascular dysfunction and resulting ischemia, which may potentially enable immediate diagnosis and endotyping of CMD-INOCA subgroups during the invasive assessment of first ANOCA episode, obviating the need for further ischemia-studies such es SPECT, which have considerably higher costs and lower sensitivity. Major coronary arteries of patients aged between 18 - 75 without obstructing coronary artery disease who have previously documented ischemia with non-obstructed coronary arteries (INOCA) via coronary angiogram and myocardial perfusion scan will be evaluated simultaneously with IC-ECG and intracoronary Doppler during rest and under adenosine induced hyperaemia. Performance of the combined system to identify Coronary Microvascular Dysfunction with structural and functional subgroups as defined by abnormal Coronary Flow Reserve (CFR) and Hyperemic Microvascular Resistance (HMR) and Ischemia in downstream territories of same vessel area (as defined by perfusion scan) is intended to be determined. The investigators also intend to interrogate the possible relationship between dynamic changes in IC-ECG parameters and invasively obtained intracoronary hemodynamic data.
