Оценка кардиологической Морфологические и функциональные изменения в модели мышей поперечных сужением аорты по ЭхоКГ визуализации

Overview

This protocol outlines a noninvasive method to assess cardiac structural and functional changes in a mouse model of heart disease induced by transverse aortic constriction (TAC). Utilizing echocardiographic imaging techniques, this approach enables researchers to monitor the progression of heart disease over time.

Key Study Components
