Cardiothoracic diseases result in substantial morbidity and mortality. Chest computed tomography (CT) has been an imaging modality of choice for assessing a host of chest diseases, and technologic advances have enabled the emergence of coronary CT angiography as a robust noninvasive test for cardiac imaging. Technologic developments in CT have also enabled the application of dual-energy CT scanning for assessing pulmonary vascular and neoplastic processes. Concerns over increasing radiation dose from CT scanning are being addressed with introduction of more dose-efficient wide-area detector arrays and iterative reconstruction techniques...

A 36-year-old woman was seen with complaints of exertional chest pain and shortness of breath. Her medical history included atrial fibrillation and diabetes. Physical examination was unremarkable except for an irregular cardiac rhythm. Myocardial perfusion imaging revealed the presence of a large area of infarction involving the entire anterior and apical walls and part of the anteroseptal wall with minimal periinfarct ischemia. Computed tomography coronary angiogram revealed an anomalous left main coronary artery arising from the main pulmonary artery...

Noninvasive assessment of coronary artery disease remains a challenging task, with a large armamentarium of diagnostic modalities. Myocardial perfusion imaging (MPI) is widely used for this purpose whereby cardiac positron emission tomography (PET) is considered the gold standard. Next to relative radiotracer distribution, PET allows for measurement of absolute myocardial blood flow. This quantification of perfusion improves diagnostic accuracy and prognostic value. Cardiac hybrid imaging relies on the fusion of anatomical and functional imaging using coronary computed tomography angiography and MPI, respectively, and provides incremental value as compared with either stand-alone modality...

BACKGROUND: Blunt cardiac trauma encompasses a wide range of clinical entities, including myocardial contusion, cardiac rupture, valve avulsion, pericardial injuries, arrhythmia, and even myocardial infarction. Acute myocardial infarction due to coronary artery dissection after blunt chest trauma is rare and may be life threatening. Differential diagnosis of acute myocardial infarction from cardiac contusion at this setting is not easy. CASE PRESENTATION: Here we demonstrated a case of blunt chest trauma, with computed tomography detected myocardium enhancement defect early at emergency department...

The location of the heart within the thorax varies significantly between individuals. The resultant diversity of the anatomical cardiac long axis, however, and its determinants, have yet to be systematically investigated. We enrolled 100 consecutive patients undergoing coronary arterial computed tomographic angiography, decomposing the vector of the anatomical cardiac long axis by projecting it to horizontal, frontal, and sagittal planes. The projected vectors on each plane were then converted into three rotation angles using coordinate transformation...

Liver transplantation is the best treatment option for early-stage hepatocellular carcinoma, liver cirrhosis, fulminant liver failure, and end-stage liver diseases. Even though advances in surgical techniques and perioperative care have improved postoperative outcomes, perioperative cardiovascular complications are a leading cause of postoperative morbidity and mortality following liver transplantation. Ischemic coronary artery disease (CAD) and cardiomyopathy are the most common cardiovascular diseases and could be negative predictors of postoperative outcomes in liver transplant recipients...

BACKGROUND: Obstructive sleep apnea syndrome (OSAS) is reported to be associated with hypertension, coronary artery disease, atrial fibrillation, and heart failure. Galectin-3 plays an important role in the regulation of inflammation, development of cardiac fibrosis and remodeling. A significant relationship between galectin-3 and the total number of coronary plaques and the macrocalcified plaque structures of patients with type 2 DM has been reported. AIM: The aim of this study was to investigate the association between galectin-3 level and coronary plaque burden as well as OSAS severity in patients with obstructive sleep apnea syndrome...

Myocardial infarction (MI), a subset of acute coronary syndrome, is damage to the cardiac muscle as evidenced by elevated cardiac troponin levels in the setting of acute ischemia. Coronary artery disease is the leading cause of mortality in the United States. Chest pain is a common presentation in patients with MI; however, there are multiple noncardiac causes of chest pain, and the diagnosis cannot always be made based on initial presentation. The assessment of a possible MI includes evaluation of risk factors and presenting signs and symptoms, rapid electrocardiography, and serum cardiac troponin measurements...

BACKGROUND: Psychological distress caused by cardiovascular pre-participation screening (PPS) may be a reason not to implement a PPS program. We assessed the psychological impact of PPS, including cardiac computed tomography (CT), in 318 asymptomatic sportsmen aged ≥45 years. METHODS: Coronary artery disease (CAD) was defined as a coronary artery calcium score ≥100 Agatson units and/or ≥50% luminal stenosis on contrast-enhanced cardiac CT. Psychological impact was measured with the Impact of Event Scale (IES) (seven items) on a six-point scale (grade 0-5)...

BACKGROUND: -Cardiomyocytes are resistant to radiation. However, cardiac radiation exposure causes coronary microvascular endothelial inflammation, a perturbation implicated in the pathogenesis of heart failure (HF) and particularly, HF with preserved ejection fraction (HFpEF). Radiotherapy for breast cancer results in variable cardiac radiation exposure and may increase the risk of HF. METHODS: -We conducted a population-based case-control study of incident HF in 170 female residents of Olmsted County, Minnesota (59 cases and 111 controls) who underwent contemporary (1998-2013) radiotherapy for breast cancer utilizing computed tomography-assisted radiotherapy planning...

BACKGROUND AND AIMS: Excess weight is a widespread condition related to increased risk of coronary heart disease (CHD). Sarcopenia is a catabolic pathway common of the aging process and also associated with CHD. In the elderly, both changes occur concurrently and it remains unclear the relative contribution on CHD risk. We aimed to investigate whether sarcopenia, excess weight, or both are associated with subclinical atherosclerosis and/or endothelial dysfunction in very elderly individuals...

OBJECTIVES: This study sought to evaluate the effects of inflammatory sarcoid disease on coronary circulatory function and the response to immune-suppressive treatment. BACKGROUND: Although positron emission tomography assessment of myocardial inflammation is increasingly applied to identify active cardiac sarcoidosis, its effect on coronary flow and immune-suppressive treatment remains to be characterized. METHODS: Thirty-two individuals, who were referred for positron emission tomography/computed tomography, were evaluated for known or suspected cardiac sarcoidosis applying (18)F-fluorodeoxyglucose to determine inflammation and (13)N-ammonia to assess for perfusion deficits following a high-fat/low-carbohydrate diet and fasting state >12 h to suppress myocardial glucose uptake...

Pheochromocytoma has been called 'the great mimic', capable of presenting itself as many other medical conditions. We present a 58-year-old woman admitted with recurrent episodes of nausea and vomiting and high blood pressure. Elevated cardiac biomarkers and diffuse ST-T abnormalities on electrocardiography suggested myocardial injury. However the biochemical and electrocardiography abnormalities normalized in a few hours. The next day the combination of fever, mental disorientation and confusion associated with elevated levels of C-reactive protein and leukocytosis suggested infection of central neural system...

Specific signatures of culprit lesions detected on multidetector computed tomography (MDCT) were identified as predictors of periprocedural myocardial injury (PMI) after percutaneous coronary intervention (PCI) in patients with stable angina; PMI has been shown to be associated with a worse prognosis. We investigated the association between preprocedural culprit lesion characteristics, assessed by MDCT, and PMI after PCI for chronic total occlusion (CTO). From three medical centers, 81 patients who underwent pre-PCI MDCT and CTO PCI, and systematic cardiac troponin (cTn) sampling before and after PCI, were included...
