Abstract
Chaotic nature of myocardial ultrasonic radio-frequency (RF) signals have been shown to reflect myocardial tissue properties in humans (1). The decreased plasma adiponectin levels or increased plasma aldosterone levels play an important role in cardiac hypertrophy and fibrosis in patients with hypertension (2)(3). Quasistatic behavior was prevalent in the RF signals in the hypertensive patients. Regression of myocardial fibrosis changed RF signals from quasistatic to chaotic nature, and restraint of myocardial hypertrophy, vice versa. I. INTRODUCTION Chaotic nature of myocardial ultrasonic radio-frequency (RF) signals reflects myocardial tissue properties; however, it is unclear whether it changes after treatment in accord with changes in myocardial properties in hypertensive patients.
