Hypertrophic transformation is important in many forms of heart disease including ischemia, hypertension,
heart failure, and valvular disease. In each of these types of cardiac pathology, hypertrophy has a crucial compensatory
function normalizing wall stress and oxygen consumption. At the same time, hypertrophy may be an early phase in a pathogenic
process that culminates in heart failure. The molecular signaling pathways involved in the pathogenesis of hypertrophy
and transition to heart failure are the subject of intense investigation. To establish the cardiac hypertrophic animal
model, we performed the microsurgery of thoracic aortic banding (TAB) under stereomicroscope, the systolic blood pressure
of TAB-operated mice and their control sham-operated mice were measured using tail cuff plethysmography at 3
weeks after microsurgery. The systolic blood pressure was increased at 3 week after TAB microsurgery compared to sham
(145 vs. 105 mmHg). These results suggest that TAB-operated animal model might be available to investigate of cardiogenic
hypertension based on cardiac hypertrophy.
