Electrocardiographic signs of cardiac ischemia at rest and during exercise in patients with COPD traveling to 3,100 m: data from a randomized trial of acetazolamide by Marla Christen, Marla Christen, Aline Buergin, Aline Buergin, Maamed Mademilov, Maamed Mademilov, Laura Mayer, Laura Mayer, Simon R. Schneider, Simon R. Schneider, Mona Lichtblau, Mona Lichtblau, Talant M. Sooronbaev, Talant M. Sooronbaev, Silvia Ulrich, Silvia Ulrich, Konrad E. Bloch, Konrad E. Bloch, Michael Furian, Michael Furian

“…IntroductionIn patients with chronic obstructive pulmonary disease (COPD), oxygen delivery to the heart may be impaired during travel at altitude. We assessed electrocardiogram (ECG)-derived signs of cardiac ischemia and the effects of preventive acetazolamide therapy in COPD patients traveling to high altitudes.MethodsPatients with COPD [Global Initiative for Chronic Obstructive Pulmonary Disease (GOLD) grades 2–3] and a predicted forced expiratory volume in 1 s (FEV1) of 66 ± 11% (mean ± SD), aged 57 ± 8 years, and living <1,000 m were included in this analysis of secondary outcomes from a randomized placebo-controlled double-blind trial (www.clinicaltrials.gov, NCT03156231). …”

A Deep-Learning Approach to a Volumetric Radio Environment Map Construction for UAV-Assisted Networks by Bethelhem S. Shawel, Dereje H. Woldegebreal, Sofie Pollin

“…The proposed approach addresses the limitations of existing approaches by learning the spatial correlation of wireless propagation channel characteristics and visualizing REM in areal and height/altitude dimensions using deep learning models. Specifically, the approach uses two deep learning-based models: volume-to-volume (Vol2Vol) VREM with 3D-generative adversarial networks and sliced VREM with altitude-aware spider-UNets. …”
