The invention relates to the technical field of
biomedicine and cardiovascular
disease treatment, and discloses application of an Aralar myocardial overexpression
virus in preparation of a
medicine for treating
heart failure. The related product is a
gene therapy preparation containing an effective amount of AAV9-cTnT-Aralar, and can be matched with pharmaceutically acceptable carriers, diluents and other auxiliary materials, and the preparation is an injection type. The preparation method comprises the following steps: firstly, constructing a
cardiac troponin T-carrying
promoter and an AAV9 carrier of an Aralar coding
nucleic acid to form a recombinant adeno-associated
virus, and then matching the
virus with proper auxiliary materials to prepare the preparation. The product can be used for treating
heart failure accompanied with mitochondrial dysfunction, can realize heart targeted delivery and
myocardial cell specific overexpression of Aralr, relieves the
heart failure course by improving the
myocardial cell mitochondrial function and
dynamic balance, and is good in preparation stability, convenient in administration and adaptive to clinical application requirements.
