Research Article: 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

Date Published: 2025-02-06

Abstract:
Introduction: In 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.
