- Left ventricular morphological parameters Echocardiographic measurements at 30 weeks of modeling (10 weeks of dosing) showed that the valsartan group (10 mg/kg) was administered 10 weeks after gavage compared with the diabetic model control rats treated with NaCl drinking water. In the compound A group (18 mg/kg), the PWd of the rats was slightly thickened, and the LVDd and LVDs were slightly decreased.
- Echocardiographic measurements at 36 weeks (16 weeks of administration) showed that the morphological changes of the left ventricle in each drug-administered group were compared with those in the diabetic model-controlled rats treated with NaCl drinking water. The results were similar at 30 weeks (10 weeks of administration).
- echocardiography showed that the valsartan group was administered 16 weeks after gavage compared with the saline-controlled diabetic control rats.
- A can improve the diastolic function of the ventricles of diabetic rats treated with NaCl.
- LVSP left ventricular systolic pressure
- LVEDP left ventricular end diastolic pressure
- BNP B-type natriuretic peptide
- NC normal control
- MC model control
