Clinical characteristics and predictors for cardiovascular system involvement in patients with Behçet's disease.

Objectives: The purpose of this study is to analyse the clinical characteristics of Behçet's disease (BD) patients in China with or without cardiovascular system involvement, and to develop a risk model to identify factors related to cardiovascular involvement in BD.

Methods: This retrospective cohort study, using the information on BD in Shenzhen People's Hospital from January 2000 to December 2021, included 95 patients: BD patients without cardiovascular system involvement (n=63) and with cardiovascular system involvement (n=32).

Results: Patients with BD who were males and had a combination of hypertension and a longer duration of disease were more likely to have cardiovascular involvement (p < 0.

Sono-assisted-thrombolysis by three-dimensional diagnostic ultrasound improves epicardial recanalization and microvascular perfusion in acute myocardial infarction.

Background: This study aimed to evaluate the multiple interactions between therapeutic ultrasound (TUS), microbubbles (MB), and recombinant tissue plasminogen activator (r-tPA) by using three-dimensional (3D) ultrasound to examine the impact of thrombolysis with r-tPA on epicardial recanalization and microcirculation in patients with acute ST-segment-elevation myocardial infarction (STEMI).

Methods: Acute thrombotic occlusion of the left anterior descending (LAD) artery was induced in 32 Bama pigs, who were fed a high-cholesterol diet and randomized into four groups: (I) a 3D-sono-assisted-thrombolysis (3D/TUS + MB + r-tPA) group; (II) a 3D/TUS + MB group; (III) a full-dose r-tPA group; and (IV) a 3D/TUS alone group. Epicardial angiographic recanalization rate, microcirculation in the at-risk myocardium, ST-segment elevation on electrocardiogram, and changes in the at-risk myocardium and the myocardial infarct area were compared between the groups.

Ultrasound-Mediated Microbubble Cavitation Transiently Reverses Acute Hindlimb Tissue Ischemia through Augmentation of Microcirculation Perfusion via the eNOS/NO Pathway.

Ultrasound-mediated microbubble cavitation improves perfusion in chronic limb and myocardial ischemia. The purpose of this study was to determine the effects of ultrasound-mediated microbubble cavitation in acute limb ischemia and investigate the mechanism of action. The animal with acute hindlimb ischemia was established using male Sprague-Dawley rats.
