Objective To explore the clinical value of echocardiographic evaluation of myocardial injury caused by pulmonary hypertension (PAH) and the correlation of oxidative stress injury. Methods Forty-eight 12-week-old SD rats were collected. They were randomly divided into 4 groups: blank control group, NaCl control group, PAH 2-week group and PAH 4-week group. After modeling, ultrasound was used to detect relevant parameters. HE and Masson staining were used to observe the distribution of myocardial cells and collagen fibers in the right ventricle. Superoxide dismutase (SOD) activity, reduced glutathione (GSH) and malondialdehyde (MDA) levels were measured, and their correlations with ultrasound parameters were evaluated. Results The ultrasound-related parameters of rats in the PAH group changed significantly and gradually increased.HE and Masson staining showed that cardiac myocytes were enlarged and collagen fibers in myocardial interstices were increased, and it was more obvious in the 4-week group.In the PAH group, the SOD activity and GSH levels were lower, while the MDA levels were higher, and there was a trend of change, and there was a significant correlation with ultrasound parameters. The difference was statistically significant (P<0.05). Conclusion PAH causes changes in the myocardial tissue structure of the rat right ventricle, as well as changes in oxidative stress-related indicators.
