摘要: Background. An early sign of ventricular remodeling is increased left mass (LVM) which over time may lead to hypertrophy, the strongest predictor cardiovascular morbidity and mortality, other than advancing age. Methods. 62 (30 TM; 32 CTL) African American adolescents (age 16.2 ± 1.3 years) with high normal systolic BP were randomly assigned either 4-month Transcendental Meditation (TM) or health education control groups. The echocardiographic-derived measure LVM index (LVMI = LVM/ht(2.7)) was measured before after TM study at followup. 2D-guided M-mode echocardiography using a Hewlett Packard 5500 echosonograph used determine LVMI. Results. group exhibited greater decrease in LVMI followup compared CTL (-2.6 versus +0.3 gm/ht(2.7), P < 0.04). lesser increase BMI follow-up (0.2 1.6 1.1 1.4, 0.03). Conclusion. These findings indicate that among prehypertensive adolescents, 4 months heath resulted significant LVMI, these changes maintained follow-up.
