Traditional prognostic risk assessment in patients undergoing non-invasive imaging is based upon a limited selection of clinical and findings. Machine learning (ML) can consider greater number complexity variables. Therefore, we investigated the feasibility accuracy ML to predict 5-year all-cause mortality (ACM) coronary computed tomographic angiography (CCTA), compared performance existing or CCTA metrics. The analysis included 10 030 with suspected artery disease follow-up from COronary CT...
Symptom-based pretest probability scores that estimate the likelihood of obstructive coronary artery disease (CAD) in stable chest pain have moderate accuracy. We sought to develop a machine learning (ML) model, utilizing clinical factors and calcium score (CACS), predict presence CAD on computed tomography angiography (CCTA).
The density of atherosclerotic plaque forms the basis for categorizing calcified and noncalcified morphology plaques.To assess whether alterations in across a range measurements provide more detailed understanding disease progression.This cohort study enrolled 857 patients who underwent serial coronary computed tomography angiography 2 or years apart had quantitative plaques throughout entire artery tree. was conducted from 2013 to 2016 at 13 sites 7 countries.The main outcome progression...
Objective— We sought to examine the risk of mortality associated with nonobstructive coronary artery disease (CAD) and determine impact baseline statin aspirin use on mortality. Approach Results— Coronary computed tomographic angiography permits direct visualization CAD. To date, prognostic implications CAD potential benefit directing therapy based have not been carefully examined. A total 27 125 consecutive patients who underwent (12 enrolling centers 6 countries) were prospectively entered...
Background Patients with atrial fibrillation are known to have a high risk of mortality. There is paucity population-based studies about the impact on mortality stratified by age, sex, and detailed causes death. Methods A total 15,411 patients from Korean National Health Insurance Service-National Sample Cohort were enrolled, death identified according codes 10th revision International Classification Diseases. Results From 2002 2013, 4,479 (29%) deaths confirmed, crude rate for all-cause was...
We examined the prevalence, extent, severity, and prognosis of coronary artery disease (CAD) in individuals with without diabetes (DM) who are similar CAD risk factors.We identified 23,643 consecutive known undergoing computed tomography angiography. A total 3,370 DM were propensity matched a 1-to-2 fashion to 6,740 unique non-DM individuals. was defined as none, nonobstructive (1-49% stenosis), or obstructive (≥ 50% stenosis). All-cause mortality assessed by risk-adjusted Cox proportional...
AIM: Prior evidence observed no predictive utility of coronary CT angiography (CCTA) over the artery calcium score (CACS) and Framingham risk (FRS), among asymptomatic individuals.Whether prognostic value CCTA differs for patients, when stratified by CACS severity, remains unknown.METHODS AND RESULTS: From a 12-centre, 6-country observational registry, 3217 individuals without known disease (CAD) underwent CCTA.Individuals were categorized as: 0-10, 11-100, 101-400, 401-1000, >1000.For...
We demonstrate low-temperature growth and direct transfer of graphene–graphitic carbon films (G–GC) onto plastic substrates without the use supporting materials. In this approach, G–GC were synthesized on copper layers by using inductively coupled plasma enhanced chemical vapor deposition, enabling few-layer graphene (G) top Cu additional graphitic (GC) above layer at temperatures as low 300 °C. The patterned are not easily damaged or detached from polymer during wet etching process because...
The long-term prognostic benefit of coronary computed tomographic angiography (CCTA) findings artery disease (CAD) in asymptomatic populations is unknown. From the prospective multicentre international CONFIRM study, we evaluated subjects without known CAD who underwent both calcium scoring (CACS) and CCTA (n = 1226). Coronary included severity stenosis, plaque composition, segment location. Using C-statistic likelihood ratio tests, incremental utility over a base model that panel...
<h3>Importance</h3> Plaque morphologic measures on coronary computed tomography angiography (CCTA) have been associated with future acute syndrome (ACS). However, the evolution of calcified plaques by noninvasive imaging is not known. <h3>Objective</h3> To ascertain whether increasing density in plaque risk for ACS. <h3>Design, Setting, and Participants</h3> This multicenter case-control cohort study included individuals enrolled ICONIC (Incident Coronary Syndromes Identified Computed...
Background: Diagnosis of coronary artery disease and management strategies have relied solely on the presence diameter stenosis ≥50%. We assessed whether direct quantification plaque burden (PB) characteristics by computed tomography angiography could provide additional value in terms predicting rapid progression. Methods Results: From a 13-center, 7-country prospective observational registry, 1345 patients (60.4±9.4 years old; 57.1% male) who underwent repeated >2 apart were enrolled....
