Sep 9, 2021 · People with coronary artery disease – characterized by narrowed arteries leading to the heart – may experience shortness of breath, chest pain, dizziness and other symptoms caused by arteries being further constricted at high altitude and limiting blood flow to the heart.
Effect of Altitude on the Heart and the Lungs | Circulation
Nov 6, 2007 · Exposure to high altitude may unmask coronary artery disease, left ventricular dysfunction, or pulmonary hypertension that was asymptomatic at sea level. Nevertheless, at 2000 to 2500 m, mild hypoxemia is induced, alkalosis is minor, pH is back to normal within a day, and the reduction in exercise performance is small.
High Altitude Hazards: Stroke Risks And Prevention | MedShun
Nov 26, 2024 · High altitude exposure can cause a range of health issues, especially for those with pre-existing cardiovascular conditions. The reduced oxygen availability at high altitudes can put a lot of stress on the heart and lungs, and may even lead to sudden cardiac death.
Effect of High-Altitude Exposure in the Elderly | Circulation
Aug 19, 1997 · Exposure to high altitude results in significant arterial hypoxemia that may exacerbate preexisting cardiac or pulmonary disease.
High Altitude Exposure Among People With Cardiovascular Conditions
Jan 19, 2018 · High altitude is associated with increases in systemic blood pressure (BP), both rest and exercise heart rate (HR), and minute ventilation. Alveolar hypoxia and arterial hypoxemia induce pulmonary circulation vasoconstriction, resulting in increased pulmonary vascular resistance and pulmonary artery pressure (hypoxic pulmonary vasoconstriction).
