Key result
High altitude exposure is linked to considerably greater LV effort during exercise for comparable work.
Why the study?
The cardiac work response to treadmill exercise at high altitude in natives of high versus low altitude regions was not well characterized.
Does high altitude alter the left ventricular work response to treadmill exercise in native populations?
Observational
Yes
Does high altitude alter the left ventricular work response to treadmill exercise in native populations?
High altitude natives performing exercise at high altitude require considerably greater left ventricular effort for comparable external work compared to low altitude natives at sea level.
No takes yet. Share an insight, caveat, or question.
Exercise-induced LV responses appear comparable across altitudes; leaves open relevance to modern clinical populations or interventions.
Theilen et al. (1955) reported an observational. High altitude exposure vs. Low altitude exposure was evaluated on Left ventricular response to treadmill exercise. High altitude exposure resulted in considerably greater left ventricular effort during treadmill exercise for comparable amounts of external work compared to low altitude exposure.
