Pathophysiology, Diagnosis, and Management of Coronary Artery Disease in the Setting of Atrial Fibrillation.

Atrial fibrillation (AF) and coronary artery disease are frequently associated and, when so, lead to a grim prognosis. Recent studies suggest the presence of interconnected pathophysiological pathways between the 2 conditions that can promote and aggravate each other, igniting a vicious cycle. Notwithstanding, in contrast with the attention dedicated to the management of antithrombotic treatment, research on other aspects of coronary artery disease in AF is only recently gaining traction.

Ablation of Atrioventricular Nodal Reentrant Tachycardia with Focal Cryoablation, Compared with Radiofrequency Ablation: Single-Center Experience.

Background: The ablation of atrioventricular nodal reentrant tachycardia (AVNRT) with cryoablation is an alternative to radiofrequency (RF) ablation in patients due to the low risk of total atrioventricular block. An increase in early-late recurrences after cryoablation is reported as an important disadvantage.

Objectives: In this study, we aimed to compare the acute procedural success and the long-term recurrence rates of patients, with AVNRT who underwent methods.

Occupational Exposure to Charcoal Smoke and Dust, a Major Risk Factor for COPD: A Multiregional Cross-Sectional Study in the Democratic Republic of Congo.

Background: Occupational exposure to charcoal smoke and dust is a threat to workers' respiratory systems.

Research Question: What is the prevalence of COPD in charcoal workers compared with that of farmers in rural areas of Democratic Republic of Congo (DRC)?

Study Design And Methods: This cross-sectional, comparative, and multisite study was performed in the charcoal-producing provinces of southwestern DRC. We randomly included charcoal workers and compared them with farmers (age range, 18-70 years).

Effect of a new resistance training method on the metaboreflex in cardiac rehabilitation patients: a randomized controlled trial.

Patients with cardiac disease exhibit exaggerated sympathoexcitation, pressor, and ventilatory responses to muscle metaboreflex activation (MMA). However, the effects of cardiac rehabilitation (CR) and especially resistance training (RT) modalities on MMA are not well known. This study investigated how CR impacts MMA in such patients, specifically examining the effects of two different resistance training (RT) protocols following 12 weeks of CR.
