Rat sepsis model was established to detect left ventricular systolicpressure (LVSP), left ventricular end-diastolic pressure (LVEDP), and maximalrate of increase/decrease of left ventricular pressure (±dp/dtmax).Myocardial injury markers serum cardiac troponin I (cTnI), myocardial kinaseisoenzyme (CK-MB), and inflammatory factors were detected by enzyme-linkedimmunosorbent assay (ELISA). This evidence concerns the gene TNNI3 and Sepsis.
