Presence and extent of coronary calcified plaque evaluated by coronary computed tomographic angiography are independent predictors of ischemic stroke in patients with suspected coronary artery disease
Abstract Although ischemic stroke and coronary artery disease (CAD) share common risk factors and pathophysiology, the risk of stroke in patients with CAD remains unclear. We sought to evaluate the risk of ischemic stroke in patients with suspected CAD according to coronary computed tomographic angiography (CCTA) and single-photon emission computed tomography (SPECT) findings. Presence, severity, and extent of CAD were evaluated in 1137 patients with suspected CAD who underwent CCTA and SPECT. Primary outcome was the occurrence of ischemic stroke. During follow-up (median 26 months), ischemic stroke was obse...

Thrombus composition in acute ischemic stroke: A histopathological study of thrombus extracted by endovascular retrieval
Conclusion HAS was significantly associated with early phase thrombus composition. This may enable the prediction of thrombus composition and allow for targeted selection of therapeutic modality.

Transoesophageal echocardiography prior to catheter ablation could be avoided in atrial fibrillation patients with a low risk of stroke and without filling defects in the late-phase MDCT scan: A retrospective analysis of 783 patients
ConclusionsFor AF patients with low risk of stroke, when MDCT images showed no filling defect in the late phase, TEE prior to catheter ablation can be avoided.Key Points•MDCT can help detect the presence of LAA thrombus.•TEE can be avoided when late-phase MDCT shows no filling defect.•TEE is required in patients whose MDCT images indicate thrombus.

Quantitative computed tomography of pulmonary emphysema and ventricular function in chronic obstructive pulmonary disease patients with pulmonary hypertension.
CONCLUSION: The study revealed that percent emphysema is correlated with RV dysfunction among COPD patients with PH. Based on our findings, percent emphysema can be considered for use as an indicator to predict the severity of right ventricular dysfunction among COPD patients. PMID: 25469102 [PubMed - in process]

Coronary artery calcium scores and cardiovascular risk factors in 31,545 asymptomatic Korean adults
Abstract The aims of this study were to identify the distribution of coronary artery calcium score (CACS) by age group and cardiovascular (CV) risk factors and to evaluate the association between CV risk factors and CACS classification in asymptomatic adults. The study included 31,545 asymptomatic Koreans, over 20 years of age with no previous history of malignancy, proven coronary artery disease, or stroke, who underwent CACS computed tomography at the Health Promotion Center, Samsung Medical Center, between January 2005 and June 2013. Mean (±SD) age was 53.8 (±8.5) years overall, 56.1 (±8.3) in men, and 53.3 ...

Pericardial, But Not Hepatic, Fat by CT Is Associated With CV Outcomes and Structure: The Multi-Ethnic Study of Atherosclerosis
Conclusions Pericardial fat is associated with poorer CVD prognosis and LV remodeling, independent of insulin resistance, inflammation, and CT measures of hepatic fat.
