Abstract Aims To evaluate the effectiveness and safety of cryoballoon ablation (CBA) compared with radiofrequency (RFA) for symptomatic paroxysmal or drug-refractory persistent atrial fibrillation (AF). Methods results Prospective cluster cohort study in experienced CBA RFA centres. Primary endpoint was ‘atrial arrhythmia recurrence’, secondary endpoints were as follows: procedural results, safety, clinical course. A total 4189 patients included: 2329 (55.6%) 1860 (44.4%).

We demonstrated the hypothesis that combined exercise improves body composition, cardiometabolic risk factors, blood pressure (BP), arterial stiffness, and physical functions, in obese older men. Older men (n = 20) were randomly assigned to training (EXP; n 10) or control groups (CON; 10). The was comprised of elastic-band resistance walking/running on a treadmill bicycle at 60-70% maximal heart rate for 3 days/weeks. EXP showed significant decreases weight, mass index, %body fat (p < 0.05)....

With the emergence of coronavirus disease 2019, individuals have been participating in online exercises to maintain their health while avoiding infection. Among these exercises, Pilates intervention is a popular modality. This study aimed examine differences between and face-to-face interventions terms various physiological parameters included 30 middle-aged (age 43.3 ± 5.5 years) with obesity. These were randomly divided into group (FPG), an (OPG), control (CG). The FPG OPG performed 60-min...

All dependent variables (body ANS...
Hypoxic training is believed to be generally useful for improving exercise performance in various athletes. Nowadays, intervention hypoxia recognized as a new therapeutic modality health promotion and disease prevention or treatment based on the lower mortality prevalence of people living high-altitude environments than those low-altitude environments.

Pulsatile tinnitus may result from turbulent flow within the internal carotid artery (ICA). Atherosclerotic stenosis is a rare but well-known cause of pulsatile tinnitus. The classical treatment was endarterectomy or ligation for proximal ICA disease stenting distal lesions. Endovascular techniques offer new ways to treat atherosclerotic vascular We describe two cases caused by petrous segment and treated stent-assisted angioplasty.
