Coronary artery calcification and family history of myocardial infarction in the Dallas heart study.
Published in JACC. Cardiovascular imaging
This study aimed to investigate the independent and joint associations between family history of myocardial infarction (FH) and coronary artery calcification (CAC) with incident coronary heart disease (CHD). FH and CAC are associated with each other and with incident CHD. It is not known whether FH retains its predictive value after CAC results are...
Geometric Characterization of Patient-Specific Total Cavopulmonary Connections and its Relationship to Hemodynamics
Published in JACC: Cardiovascular Imaging
Total cavopulmonary connection (TCPC) geometries have great variability. Geometric features, such as diameter, connection angle, and distance between vessels, are hypothesized to affect the energetics and flow dynamics within the connection. This study aimed to identify important geometric characteristics that can influence TCPC hemodynamics. Anato...
Predictors of inaccurate coronary arterial stenosis assessment by CT angiography.
...Published in JACC. Cardiovascular imaging
We identified clinical and readily discernible imaging characteristics on CTA predicting inaccurate CTA diagnosis of obstructive CAD defined by QCA. Knowledge and appropriate considerations of these features may improve the diagnostic accuracy in clinical CTA interpretation. (Diagnostic Accuracy of Multi-Detector Spiral Computed Tomography Angiogra...
Temporal trends in the utilization of echocardiography in Ontario, 2001 to 2009.
Published in JACC. Cardiovascular imaging
The purpose of this study was to examine utilization and growth in echocardiography among the general population of Ontario between 2001 and 2009. The age- and sex-adjusted rates of echocardiography grew from 39.1 per 1,000 persons in 2001 to 59.9 per 1,000 persons in 2009, for an annual rate of increase of 5.5%. Repeat echocardiograms increased at...
MR imaging of carotid plaque composition during lipid-lowering therapy a prospective assessment of effect and time cours...
...Published in JACC. Cardiovascular imaging
Intensive lipid therapy significantly depletes carotid plaque lipid. Statistically significant plaque lipid depletion is observed after 1 year of treatment and continues in the second year, and precedes plaque regression. (Using Magnetic Resonance Imaging to Evaluate Carotid Artery Plaque Composition in People Receiving Cholesterol-Lowering Medicat...
Association between IVUS findings and adverse outcomes in patients with coronary artery disease: the VIVA (VH-IVUS in Vu...
...Published in JACC. Cardiovascular imaging
The purpose of this study was to determine whether thin-capped fibroatheromata (TCFA) identified by virtual histology intravascular ultrasound (VH-IVUS) are associated with major adverse cardiac events (MACE) on individual plaque or whole patient analysis. Post-mortem studies have identified TCFA as the substrate for most myocardial infarctions. Ho...
The impact of obesity on the left ventricle: the Multi-Ethnic Study of Atherosclerosis (MESA).
Published in JACC. Cardiovascular imaging
The purpose of this study was to evaluate the relationship of left ventricular (LV) remodeling assessed by cardiac magnetic resonance to various measures of obesity in a large population-based study. Obesity is a well-known risk factor for cardiovascular disease, yet its relationship with LV size and function is poorly understood. A total of 5,098 ...
Interventional cardiovascular magnetic resonance imaging: a new opportunity for image-guided interventions.
Published in JACC. Cardiovascular imaging
Cardiovascular magnetic resonance (CMR) combines excellent soft-tissue contrast, multiplanar views, and dynamic imaging of cardiac function without ionizing radiation exposure. Interventional cardiovascular magnetic resonance (iCMR) leverages these features to enhance conventional interventional procedures or to enable novel ones. Although still aw...
Relationship between baseline coronary calcium score and demonstration of coronary artery stenoses during follow-up MESA...
Published in JACC. Cardiovascular imaging
The MESA (Multi-Ethnic Study of Atherosclerosis) is a population-based study of 6,814 men and women. We sought to analyze the relationship between the extent of coronary artery calcium (CAC) at baseline and the severity of coronary stenoses in clinically indicated coronary angiography studies during follow-up. CAC is an established predictor of maj...
