Impaired glucose metabolism is associated with an increased risk of cardiovascular complications, and coronary artery spasm is thought to underlie the development of coronary artery disease. Intraday glucose variability (GV) accelerates oxidative stress and inflammatory cytokine release, but its impact on coronary artery spasm remains unclear. This study investigated the relationship between intraday GV and coronary artery spasm. The study included 50 patients with dysglycemia and suspected coro...

In almost every type of artificial valve, structural failure has been described. We are reporting on a case of a sudden leaflet escape of an Edwards TEKNA mitral valve prosthesis 12 years after implantation. The patient had a sudden onset of dyspnea and severe pulmonary edema with subsequent cardiogenic shock. An emergency mitral replacement was successfully performed. A multi-detector computed tomography scanning and three-dimensional imaging showed two fragments that had embolized in the termi...

Vulnerable plaque disruption was suggested as a primary cause of acute coronary syndrome. This study investigated the impact of malondialdehyde-modified low-density lipoprotein (MDA-LDL) on whole coronary plaque vulnerability, based on multislice-computed tomography (MSCT). We included 197 patients that were not receiving lipid-lowering therapy. We retrospectively analyzed MSCT and MDA-LDL measurements. We defined a CT-derived vulnerable plaque as a plaque with a remodeling index > 1.10 and a me...

A 46-year-old woman was referred to our hospital due to chest pain. Twelve-lead electrocardiogram revealed ST-segment elevation suggesting acute myocardial infarction. Emergent coronary angiography showed diffuse narrowing and occlusion in the middle to distal left anterior descending artery (LAD). To investigate the cause of occlusion, an intravascular ultrasound (IVUS) examination was performed and we diagnosed spontaneous coronary artery dissection (SCAD) as the cause of occlusion. After a cu...

Abstract Objective Endothelial dysfunction of the coronary artery is thought to lead to the development of coronary spasms. Epicardial adipose tissue may be a marker of coronary atherosclerosis. This study investigated the diagnostic impact of epicardial fat volume (EFV), quantified with non-contrast electrocardiogram (ECG)-gated computed tomography (CT), on ergonovine-induced coronary spasms. Methods We included 97 patients with suspected coronary spastic angina who underwent ECG-gated CT and a...

A 58-year-old man was referred to our hospital because of chest pain. The 12-lead electrocardiogram (ECG) revealed ST-segment elevation in II, III, and a Vf with advanced heart block. Transthoracic echocardiography demonstrated aortic root dilatation at the sinus of Valsalva, moderate aortic regurgitation, and decreased wall motion in the inferior part of the left ventricle. Non-ECG-gated enhanced computed tomography (CT) did not reveal an aortic dissection. The patient underwent emergent corona...

An 81-year-old man was referred to our emergency department with severe persistent chest pain. One year before presentation at our department, his 12-lead electrocardiogram (ECG) revealed a normal QRS pattern during the period of normal conduction with intermittent left bundle branch block (LBBB). His ECG immediately after arrival showed deep T-wave inversion in the precordial leads during normal conduction. During LBBB, there was mild ST-segment elevation with poor R-wave progression across the...
