Abstract
BACKGROUND: Cardiac hypertrophy induced by pressure overload is one of the important causes of heart failure and sudden cardiac death. At present, there are few studies on the outcome of left ventricular hypertrophy and left ventricular function after complete pressure load removal. OBJECTIVE: This study aims to better simulate the changes of left ventricular structure and function during the process of left ventricular pressure overload and deloading, and to explore the application of echocardiography in it. METHODS: In this study, healthy male (BALB/C) mice were used as research objects to establish an ascending aorta constriction model, to carry out echocardiographic and hemodynamic examinations, to establish an ascending aorta deconstriction model in mice, and to carry out echocardiographic and hemodynamic examinations. RESULTS: Compared with the sham operation group, the left ventricular end-systolic diameter (LVESD), left ventricular end-diastolic diameter (LVEDD), interventricular septal (IVS), and left ventricular posterior wall (LVPW) in the constriction operation group were significantly increased (P=.02, P=.02, P=.02, and P=.02, respectively). LVESD, LVEDD, IVS, and LVPW in the early and late constriction groups were significantly decreased, and the degree of decrease in the early group was greater than that in the late group; compared with the sham operation group, left ventricular diastolic pressure in the constriction operation group increased significantly at 9 and 15 weeks after operation (P=.03). Left ventricular systolic pressure at 15 weeks after operation decreased to a certain extent but was higher than that of the sham operation group (P=.02). The maximal rate of the increase of left ventricular pressure at 3 weeks, 9 weeks, and 15 weeks after operation decreased significantly (P=.03, P=.02, and P=.02, respectively). CONCLUSIONS: In this study, the ascending aorta coarctation model and descending aorta coarctation model were successfully established, which verifies the value of echocardiography information data monitoring in the treatment of left ventricular circulation disorders and the evaluation of surgical treatment.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
