Rapid progression of heart failure secondary to radioactive iodine treatment of hyperthyroidism: A case report.

Background: The deterioration of thyroid health is involved in the progression of heart failure (HF). This is usually a lengthy process, so there are almost no reports on its rapid development. Here we report a case of a young male who rapidly developed hypothyroid cardiomyopathy secondary to radioactive iodine treatment, suggesting that severe HF might occur even after a short period of hypothyroidism.

Death, discharge and arrhythmias among patients with COVID-19 and cardiac injury.

Background: Cardiac injury is common in severe coronavirus disease 2019 (COVID-19) and is associated with poor outcomes. We aimed to study predictors of in-hospital death, characteristics of arrhythmias and the effects of QT-prolonging therapy in patients with cardiac injury.

Methods: We conducted a retrospective cohort study involving patients with severe COVID-19 who were admitted to Tongji Hospital in Wuhan, China, between Jan.

A new method for the assessment of endothelial function with peripheral arterial volume.

Background: Currently, many methodological approaches have been developed to assess peripheral endothelial function. However, a development of the noninvasive and automated technique for routinely assessing endothelial function is still required. We evaluated the potential value of a new method to measure peripheral endothelial function with reactive hyperemia peripheral arterial volume (RH-PAV) in patients with chest pain.

Realization of fully automated quantification of left ventricular volumes and systolic function using transthoracic 3D echocardiography.

Background: Study on automated three-dimensional (3D) quantification of left heart parameters by using Heartmodel software is still in the early stage and fully automatic analysis was not clearly achieved. The aim of our study was to evaluate the performance of this new technology in measuring left ventricular (LV) volume and ejection fraction (EF) in patients with a variety of heart diseases on the basis of rationally determining the default endocardial border values.

Methods: Subjects with a variety of heart diseases were included prospectively.

The effects of amlodipine and S(-)-amlodipine on vascular endothelial function in patients with hypertension.

Background: Amlodipine has been shown to improve vascular endothelial function in hypertensive patients, but whether S(-)-amlodipine has a similar effect remains controversial. This study compared the effects of amlodipine and S(-)-amlodipine on vascular endothelial function in hypertensive patients and investigated relevant mechanisms of action in cell culture.

Methods: Twenty-four patients with essential hypertension received amlodipine and S(-)-amlodipine for 6 weeks in a randomized, crossover study.

Primary pulmonary artery rhabdomyosarcoma.

A 69-year-old woman presented with a 4-month history of dyspnoea and radiating upper-right quadrant pain and oedema in her lower extremities for more than 20 days. The ultrasonographic study of the heart revealed the adherence of a substantive hypoechoic mass (73 x 34 mm) to the antelateral wall of the pulmonary artery and resultant pulmonary stenosis. Computed tomographic imaging of the pulmonary artery revealed an irregularly shaped filling defect (approximately 41 x 39 x 59 mm) in the main pulmonary artery.
