Abstract: Objective: This article investigated the changes of some biochemical markers and cardiac function in chronic heart failure (CHF), and provided the basis for the diagnosis of CHF.Methods: New Zealand rabbit CHF model was established using adriamycin (ADR). Twenty New Zealand rabbits were randomly divided into model group (n=15) and control group (n=5), injected with ADR and saline solution via the ear vein respectively, 2 times a week, lasting for 8 weeks. After that, myocardial enzymes, carotid artery pressure, echocardiogram (ECG) and phonocardiogram (PCG) of all New Zealand rabbits were detected and recorded.Results: Compared with control group, all parameters of the model group were changed significantly (P<0.05).Conclusion: CHF leads to myocardial damage in New Zealand rabbits, decreased systolic and diastolic function, cardiac reserve index can be used to assess cardiac function.

Key words: chronic heart failure, New Zealand rabbits, cardiac function, cardiac reserve index
