Abstract

The present invention discloses an application of neuraminidase and inhibitors thereof in myocardial ischemia and myocardial infarction, provides a correlation between neuraminidase and myocardial ischemic damage to prove the myocardial ischemic damage can be alleviated by inhibiting the activity of neuraminidase, and to prove the neuraminidase can be used as a target for screening drugs for preventing, alleviating and/or treating myocardial ischemic damage. The present invention also demonstrates the alleviating effect of neuraminidase inhibitors on myocardial ischemic damage. Neuraminidase inhibitors improves myocardial ischemic damage by reducing the level of neuraminidase. The present invention further provides a pharmaceutical preparation comprising neuraminidase inhibitor(s) and pharmaceutically acceptable carrier(s), the pharmaceutical preparation can be used for reducing the level of neuraminidase, thus improving myocardial ischemic damage.

Claims

1. A method of preventing, alleviating, or treating myocardial ischemic damage in a subject, comprising:

administering an effective amount of a pharmaceutical composition to the subject in need thereof;

wherein the pharmaceutical composition contains a compound that inhibits the activity of neuraminidase;

the myocardial ischemic damage is not influenza-associated; and

the compound is oseltamivir phosphate.
