Early diastolic mitral regurgitation in left ventricular aneurysm.

Diastolic mitral regurgitation is a type of functional mitral regurgitation that develops via a reversal of the left atrioventricular pressure gradient during diastole. This study aimed to explore the mechanism underlying early diastolic mitral regurgitation (EDMR) in patients with left ventricular (LV) aneurysms after anterior myocardial infarction (AMI) by assessing the intraventricular pressure difference using vector flow mapping. We enrolled 23 consecutive patients with LV aneurysms (with and without EDMR) and 15 healthy men as controls.

Effects of whole-body neuromuscular electrical stimulation device on hemodynamics, arrhythmia, and sublingual microcirculation.

Neuromuscular electrical stimulation has been used to treat cardiovascular diseases and other types of muscular dysfunction. A novel whole-body neuromuscular electrical stimulation (WB-NMES) wearable device may be beneficial when combined with voluntary exercises. This study aimed to investigate the safety and effects of the WB-NMES on hemodynamics, arrhythmia, and sublingual microcirculation.

Extended Sedentary Time Increases the Risk of All-Cause Death and New Cardiovascular Events in Patients With Diabetic Kidney Disease.

Background: Sedentary behavior may be an independent risk factor for cardiovascular events. This study aimed to clarify the effects of extended sedentary time in patients with diabetic kidney disease (DKD) on the risk of all-cause death and new events.

Methods and results: A prospective cohort study was performed over 39 months.

Right internal jugular vein thrombosis caused by aneurysm of right-sided aortic arch.

A right-sided aortic arch is normally asymptomatic. We report the case of an 84-year-old man with right internal jugular vein thrombosis caused by an aneurysm in a right-sided aortic arch. The patient had undergone open repair of an abdominal aortic aneurysm and had an uneventful postoperative course.

Out-of-hospital cardiac arrest related to coronary arterial spasm in three elderly patients with no obstructive coronary artery disease.

Coronary spastic angina (CSA) is relatively more common in young people than in elderly people. Here, we present three cases of elderly male patients who experienced out-of-hospital cardiac arrest (OHCA) likely due to coronary spasm-induced ventricular fibrillation (Vf) from 2013 to 2016. After defibrillation, emergency coronary arteriography demonstrated severe coronary vasospasm that resolved following intracoronary infusion of nitroglycerin in the right coronary arteries in all three patients, with no organic obstructive lesion in the coronary arteries after nitroglycerin infusion.

Successful coronary intervention for spontaneous coronary dissection in a patient with fibromuscular dysplasia.

Spontaneous coronary artery dissection (SCAD) is a reported rare cause of acute coronary syndrome (ACS) and sudden death among middle-aged women. Some institutes have recently reported fibromuscular dysplasia (FMD) concomitant with SCAD. Therefore, a survey of the presence of comorbid FMD in SCAD patients is important to obtain a definitive diagnosis and for the prediction of possible SCAD recurrence.
