Background: Catheter ablation (CA) can improve exercise tolerance and quality of life (QOL) in patients with atrial fibrillation (AF). However, its differential effects on muscle strength between paroxysmal AF (PAF) and nonparoxysmal AF (Non-PAF) remain unclear.
Methods: We evaluated 94 patients (67.

Challenges in drug development for rare diseases such as pulmonary arterial hypertension can be addressed through the use of mathematical modeling. In this study, a quantitative systems pharmacology model of pulmonary arterial hypertension pathophysiology and pharmacology was used to predict changes in pulmonary vascular resistance and six-minute walk distance in the context of oral treprostinil clinical studies. We generated a virtual population that spanned the range of clinical observations and then calibrated virtual patient-specific weights to match clinical trials.

Objective: A significant number of patients with chronic thromboembolic pulmonary hypertension (CTEPH) are not eligible for pulmonary endarterectomy and may be treated with balloon pulmonary angioplasty (BPA). Although BPA programs have recently been developed in Brazil, no results have yet been published. The objective of this study was to assess the clinical and hemodynamic progression of the first patients treated with BPA at our center.

Primary Ciliary Dyskinesia (PCD) is a rare genetic disorder requiring airway clearance techniques for mucus removal. We aimed to evaluate the feasibility and the effect of the active cycle of breathing technique (ACBT) versus oscillating positive expiratory pressure therapy (OPEP) in improving lung function and functional exercise capacity among children with PCD in Palestine. 32 PCD children (6-18 years) were included in a 12-week home-based feasibility study.

Objectives: To observe the prevalence of impaired pulmonary function during various phases of the disease course in children aged 5-18 y with dystrophinopathy. The correlation between different parameters of pulmonary dysfunction and motor function was also studied.
Methods: One hundred and thirty-three confirmed cases of Duchenne muscular dystrophy (DMD), fulfilling predefined inclusion and exclusion criteria were evaluated.
