Effects of purified eicosapentaenoic acid versus mixed eicosapentaenoic/docosahexaenoic acid pharmacotherapies on coronary plaque volume: network meta-analysis of prospective coronary imaging trials.

Background: Reduced cardiovascular event risk is observed with eicosapentaenoic acid (EPA), but EPA mixed with docosahexaenoic acid (EPA/DHA) does not show consistent benefit. Comparative effects of EPA versus EPA/DHA on coronary plaque remain unclear.

Methods: We systematically reviewed trials measuring coronary plaque volume in patients randomised to statin + EPA or statin + EPA/DHA therapy compared to statin monotherapy, and used network meta-analysis to compare percent change in total and lipid coronary plaque volumes on these treatments.

Ethnic differences in coronary plaque burden and characteristics: A matched CCTA cohort study of South Asians and non-Hispanic Whites.

Background/aims: South Asians (SA) experience a significantly higher incidence of atherosclerotic cardiovascular disease (CVD) events compared to non-Hispanic whites (NHW). However, detailed plaque characteristics in SA, particularly assessed through quantitative coronary plaque analysis using coronary computed tomography angiography (CCTA), remain under-investigated. This study aimed to compare the characteristics of coronary plaque burden between SA and NHW using CCTA.

The impact of semaglutide on liver fat assessed by serial cardiac CT scans in patients with type 2 diabetes: Results from STOP trial.

Background And Aim: The prevalence of hepatic steatosis continues to increase worldwide. Hepatic steatosis is increasingly recognized as an independent risk factor for cardiovascular mortality. However, there are limited options for the treatment of fatty liver.

AI-enabled opportunistic measurement of liver steatosis in coronary artery calcium scans predicts cardiovascular events and all-cause mortality: an AI-CVD study within the Multi-Ethnic Study of Atherosclerosis (MESA).

Introduction: About one-third of adults in the USA have some grade of hepatic steatosis. Coronary artery calcium (CAC) scans contain more information than currently reported. We previously reported new artificial intelligence (AI) algorithms applied to CAC scans for opportunistic measurement of bone mineral density, cardiac chamber volumes, left ventricular mass, and other imaging biomarkers collectively referred to as AI-cardiovascular disease (CVD).

Risk factors that predict for presence of clinically significant, noncalcified plaque in younger adults.

Objective: Coronary artery calcium (CAC) scoring may be a useful tool for assessing cardiovascular disease in young adults, particularly in those with risk factors such as hypertension, dyslipidemia, or smoking. In this study, we aimed to address the risk factors for developing noncalcified plaque in young adults by assessing total plaque burden.

Methods: A single-center retrospective cohort study was conducted among 1026 consecutive patients aged 18-45 years who underwent CAC scoring and coronary computed tomography (CT) angiograms for clinical indications.

"Anti-inflammatory Therapies in Atherosclerosis - Where are we going?".

Purpose Of Review: Inflammation has been commonly known for the past decade as a part of the pathophysiology of atherosclerosis, along with lipid accumulation. However, some patients with optimized lipid-lowering therapy still have elevated inflammatory biomarkers. Anti-inflammation therapies were developed to eradicate this residual risk.

Artificial intelligence applied to coronary artery calcium scans (AI-CAC) significantly improves cardiovascular events prediction.

Coronary artery calcium (CAC) scans contain valuable information beyond the Agatston Score which is currently reported for predicting coronary heart disease (CHD) only. We examined whether new artificial intelligence (AI) applied to CAC scans can predict non-CHD events, including heart failure, atrial fibrillation, and stroke. We applied AI-enabled automated cardiac chambers volumetry and calcified plaque characterization to CAC scans (AI-CAC) of 5830 asymptomatic individuals (52.

Exploring the relationship between epicardial fat and coronary plaque burden and characteristics: insights from cardiac ct imaging.

Epicardial adipose tissue (EAT) may enhance the risk of coronary artery disease (CAD). We investigated the relationship between EAT density (a maker of local inflammation) and coronary plaque characteristics in stable CAD patients. This study included 123 individuals who underwent coronary artery calcium scan and coronary CT angiography to evaluate CAD.

A Leaky False Pouch: Left Ventricle Pseudoaneurysm with Active Hemopericardium Detected on Cardiac Computed Tomography Angiography.

Pseudoaneurysm is a rare but fatal complication of myocardial infarction (MI). With the advances in cardiovascular disease detection and treatments, fatal structural complications post-MI are now rare. When they occur, advanced diagnostic modalities can be used for early diagnosis, aiding surgical planning, and improving prognosis.

AI-enabled cardiac chambers volumetry in coronary artery calcium scans (AI-CAC) predicts heart failure and outperforms NT-proBNP: The multi-ethnic study of Atherosclerosis.

Introduction: Coronary artery calcium (CAC) scans contain useful information beyond the Agatston CAC score that is not currently reported. We recently reported that artificial intelligence (AI)-enabled cardiac chambers volumetry in CAC scans (AI-CAC™) predicted incident atrial fibrillation in the Multi-Ethnic Study of Atherosclerosis (MESA). In this study, we investigated the performance of AI-CAC cardiac chambers for prediction of incident heart failure (HF).

AI-enabled left atrial volumetry in coronary artery calcium scans (AI-CAC) predicts atrial fibrillation as early as one year, improves CHARGE-AF, and outperforms NT-proBNP: The multi-ethnic study of atherosclerosis.

Background: Coronary artery calcium (CAC) scans contain actionable information beyond CAC scores that is not currently reported.

Methods: We have applied artificial intelligence-enabled automated cardiac chambers volumetry to CAC scans (AI-CAC) to 5535 asymptomatic individuals (52.2% women, ages 45-84) that were previously obtained for CAC scoring in the baseline examination (2000-2002) of the Multi-Ethnic Study of Atherosclerosis (MESA).

Efficacy and Safety of Iodixanol in Computed Coronary Tomographic Angiography and Cardiac Catheterization.

Iodixanol is an iso-osmolar non-ionic dimeric hydrophilic contrast agent with a higher viscosity than the monomeric agents. It is the only Food and Drug Administration (FDA)-approved iso-osmolar agent in the United States, and it is the only contrast agent with an FDA-approved indication for use in cardiac computed tomographic angiography (CCTA), to assist in the diagnostic evaluation of patients with suspected coronary artery disease. In clinical studies, it has been noted to have fewer side effects and similar image quality when compared to low-osmolar contrast media.

Evaluation of Image Quality for High Heart Rates for Coronary Computed Tomographic Angiography with Advancement in CT Technology: The CONVERGE Registry.

Objective: This study aims to evaluate image quality in patients with heart rates above or equal to 70 beats per minute (bpm), performed on a 16 cm scanner (256-slice General Electric Revolution) in comparison to a CT scanner with only 4 cm of coverage (64 slice Volume CT).

Background: Recent advancements in image acquisition, such as whole-heart coverage in a single rotation and post-processing methods in coronary computed tomographic angiography (CCTA), include motion-correction algorithms, such as SnapShot Freeze (SSF), which improve temporal resolution and allow for the assessment of coronary artery disease (CAD) with lower motion scores and better image qualities. Studies from the comprehensive evaluation of high temporal- and spatial-resolution cardiac CT using a wide coverage system (CONVERGE) registry (a multicenter registry at four centers) have shown the 16 cm CT scanner having a better image quality in comparison to the 4 cm scanner.

Methods and Reproducibility of Liver Fat Measurement Using 3-Dimensional Liver Segmentation From Noncontrast Computed Tomography in EVAPORATE Cohort.

Objective: Nonalcoholic fatty liver disease not only shares multiple risk factors with cardiovascular disease but also independently predicts its increased risk and related outcomes. Here, we evaluate reproducibility of 3-dimensional (3D) liver volume segmentation method to identify fatty liver on noncontrast cardiac computed tomography (CT) and compare measures with previously validated 2-dimensional (2D) segmentation CT criteria for the measurement of liver fat.

Methods: The study included 68 participants enrolled in the EVAPORATE trial and underwent serial noncontrast cardiac CT.

Ruptured Sinus of Valsalva Aneurysm Diagnosed on Coronary Computed Tomography Angiography in a Patient With Trisomy 13 Syndrome.

Trisomy 13 is a rare chromosomal disorder in which all or a percentage (mosaicism) of cells contain an extra 13th chromosome. Sinus of Valsalva aneurysms are rare, with an incidence of 0.1% to 3.

Coronary artery calcium progression and all-cause mortality.

Background: Coronary artery calcium (CAC) has been demonstrated as a noninvasive, low-cost means of assessing atherosclerotic burden and risk of major cardiovascular events. While it has been previously shown that CAC progression predicts all-cause mortality, we sought to quantify this association by examining a large cohort over a follow-up period of 1-22 years.

Methods: We studied 3260 persons aged 30-89 years referred by their primary physician for CAC measurement, with a follow-up scan at least 12 months from the initial scan.

Case Report: Culture-negative Prosthetic Valve Endocarditis.

Background: Prosthetic valve endocarditis can be difficult to diagnose and cause significant morbidity and mortality, especially when no culture data are available to guide therapy. Transthoracic and transesophageal echocardiograms, the studies of choice for initial endocarditis evaluation, can be less reliable due to artifact and post-surgical changes. Some less common forms of endocarditis may be difficult to culture and, due to their fastidious nature, may delay the identification of causative organisms.

Age and the power of zero CAC in cardiac risk assessment: overview of the literature and a cautionary case.

The coronary artery calcium (CAC) score is a marker of advanced coronary atherosclerosis. Numerous prospective cohorts have validated CAC as an independent marker that improves prognostication in atherosclerotic cardiovascular disease (ASCVD) beyond traditional risk factors. Accordingly, CAC is now incorporated into international cardiovascular guidelines as a tool to inform medical decision-making.

Association between coronary artery calcium and thoracic spine bone mineral density: Multiethnic Study of Atherosclerosis (MESA).

Background And Aims: Previously, osteoporosis and coronary artery disease were considered unrelated. However, beyond age, these two conditions appear to share common etiologies that are not yet fully understood. We examined the relationship between thoracic spine bone mineral density (BMD) and severity of coronary artery calcium (CAC) score.
