One-year follow-up evaluation of radiological and respiratory findings and functional capacity in COVID-19 survivors without comorbidities.

The aim of this study was to assess clinical findings, radiological data, pulmonary functions and physical capacity change over time and to investigate factors associated with radiological abnormalities after coronavirus disease 2019 (COVID-19) in non-comorbid patients. This prospective cohort study was conducted between April 2020 and June 2020. A total of 62 symptomatic in non-comorbid patients with COVID-19 pneumonia were included in the study.

Improvement of Pulmonary Function in Heart Failure Patients with Restrictive Patterns Undergoing Transcatheter Aortic Valve Replacement.

Background: This study aimed to investigate the improvement of pulmonary function in heart failure patients with restrictive patterns undergoing transcatheter aortic valve replacement (TAVR).

Methods: A total of 80 patients with heart failure and restrictive patterns undergoing TAVR due to severe aortic stenosis were included in this study. Spirometry and gas diffusion were assessed before and 4-6 months after TAVR.

Correlation between apnea-hypopnea index and Tp-Te interval, Tp-Te/QT, and Tp-Te/QTc ratios in obstructive sleep apnea.

Background: Obstructive sleep apnea (OSA) is a highly prevalent sleep disorder associated with important cardiovascular complications including ventricular arrhythmias. Tp-Te interval, Tp-Te/QT, and Tp-Te/QTc ratios are repolarization indices representing ventricular arrhythmogenic potential. These parameters are associated with ventricular arrhythmias and sudden cardiac death.
