Abstract

We suggest a new, easily applicable way of myocardial hypertrophy induction in rats. Forty randomized age-matched male Wistar rats were divided into 2 groups of 20 each: a control group and an orally administered fludrocortisone/salt group. Myocardial hypertrophy was estimated by measuring body weight, heart-weight-to-body-weight ratio and ventricular free wall thickness. Moderate myocardial hypertrophy without heart failure was established in fludrocortisone/salt group in 4 weeks. Our method is effective and low cost, and it provides a model of hypertrophic heart.
