background: diagnosis of coronary artery disease (cad) in patients with left bundle branch block (lbbb) is considered as a challenge in cardiology due to the low accuracy of noninvasive methods such as basal and stress electrocardiography (ecg). this diagnostic challenge can be reduced but not eliminated using dipyridamole as a stress method instead of exercise. the aim of this study was to ass...

introduction: we aimed to investigate of effect of left bundle branch block (lbbb) on perfusion and functional parameters in dipyridamole tc99m-mibi gated myocardial perfusion spect which may be helpful in interpretation of myocardial perfusion imaging. methods: we studied 70 patients with low pre-test probability of coronary artery disease in two groups:  35 patients with lbbb and  35 subjects...

Reversible handedness inversion is achieved in self-organized helical superstructures using a visible-light-driven macrocyclic chiral switch, as reported by Quan Li and co-workers their Research Article (e202216600). Green blue light can drive the reversible switching between left- right-handedness via cis/trans photoisomerization of azobenzene within cyclic molecular switch.

Tako-tsubo cardiomyopathy is characterized by reversible left ventricular dysfunction following emotional or surgical stress. Unlike the well-known complications of catheter ablation (CA) of atrial fibrillation (AF), Tako-tsubo cardiomyopathy has been rarely reported so far. We report a case of acute reversible left heart failure following successful CA of paroxysmal AF in a patient with a hist...
