Paget-Schroetter syndrome accompanied by pulmonary thromboembolism: A case report.

A 17-year-old male, who was involved in a baseball club, presented to our emergency department with the complaint of gradual onset of swelling of his right arm. Contrast-enhanced computed tomography showed obstruction of the proximal portion of the right subclavian vein and pulmonary thromboembolism. Venography confirmed an occluded right subclavian vein.

Relation of estimated glomerular filtration rate to the presence of coronary plaque and obstructive coronary artery disease in a zero or low coronary artery calcium score.

Objectives: Although renal dysfunction is associated with the presence of atherosclerosis, little is known about the relationship between reduced estimated glomerular filtration rate (eGFR) and the presence of atherosclerosis detected by coronary computed tomographic angiography (CCTA). This study evaluated the relation of eGFR to the presence of coronary plaque and obstructive coronary artery disease (CAD) in patients with a zero or low coronary artery calcium score (CACS).

Methods: Coronary artery calcium scoring and CCTA were performed with CT scanners.

Relation of cardiovascular risk factors and angina status to obstructive coronary artery disease according to categorical coronary artery calcium score.

Coronary artery calcium (CAC) is associated with the presence of coronary artery disease (CAD) and cardiovascular risk factors. However, the relation between cardiovascular risk factors and CAD has not yet been fully elucidated in patients with a zero or low coronary artery calcium score (CACS). The purpose of this study was to evaluate the relation of cardiovascular risk factors and angina status to obstructive CAD according to categorical CACS.

Glycosylated hemoglobin is a predictor of major adverse cardiac events after drug-eluting stent implantation in patients with diabetes mellitus.

Objectives: Diabetes mellitus is associated with the risk of restenosis and mortality after coronary stenting, but the relation between glycosylated hemoglobin (hemoglobin A1c) and prognosis has not yet been fully elucidated in patients with diabetes mellitus. The purpose of this study was to evaluate whether hemoglobin A1c is associated with a risk of major adverse cardiac events (MACE) after successful drug-eluting stent (DES) implantation in patients with diabetes mellitus.

Methods: In a retrospective study with a prospective follow-up, 206 patients with diabetes mellitus undergoing successful DES implantation were enrolled in this study.

An autopsy case of left ventricular apical ballooning probably caused by pheochromocytoma with persistent ST-segment elevation.

We describe the autopsy case of an 86-year-old man who experienced left ventricular (LV) apical ballooning with pheochromocytoma. During the follow-up period, his electrocardiogram (ECG) showed persistent ST-segment elevation in leads V3 to V6, and an echocardiogram revealed persistent LV dysfunction in the apical region. He died 64 days after admission.

Ultrasound attenuated coronary plaque as a risk factor for slow flow or no-reflow during percutaneous coronary intervention: a case report.

Slow flow or no-reflow is a serious complication during percutaneous coronary intervention (PCI), but little is known about the risk factors. A 64-year-old man underwent coronary angiography and PCI for stable angina. Pre-interventional intravascular ultrasound demonstrated an ultrasound attenuated coronary plaque, as a long eccentric bulky plaque with a marked decrease of the back echo without calcification.

Gadopentetate dimeglumine as a potential alternative contrast medium during percutaneous coronary intervention: a case report.

Background: There have not been previous reports of patients undergoing percutaneous coronary intervention (PCI) using a gadolinium chelate.

Methods And Results: A 74-year-old woman, who had a history of anaphylactic shock 4 times in response to iodinated contrast media despite preprocedural intravenous administration of hydrocortisone, was hospitalized because of unstable angina refractory to intensive medical treatment. Fully considering the risks of iodinated agents, digital subtraction coronary angiography and PCI were performed using gadopentetate dimeglumine without any side effects or complications.
