Motivation: The impact of high-altitude hypobaric hypoxia on myocardial infarction cardioprotection is a subject of ongoing research in cardiovascular studies.
Goal(s): We aimed to assess the potential protective effects of high-altitude hypobaric hypoxia in a rat model of MI using 7.0T CMR strain analysis.
Approach: We used rats model and transporting some rats to an elevation of 4,250 meters, while control rats remained at 500 meters. Then surgically induced myocardial infarctions in the rats at each elevation.
Results: The finding was that rats with MI living at high altitude had significantly better preservation of heart function compared to control rats living at 500 meters.
Impact: The outcomes of this study hold significance for the management of patients at risk of MI, particularly those residing in high-altitude environments or experiencing hypobaric hypoxia. Identifying the cardioprotective effects may result in the development of new therapeutic strategies.
