Abstract: | The time course of regression of left ventricular hypertrophy and changes in left ventricular function were followed in 52 middle-aged hypertensive patients divided into two groups: 30 treated with betablockers and 22 with methyldopa. In case of inadequate blood pressure control, diuretics and/or vasodilators were added in both groups. Blood pressure decreased significantly over a three-year follow-up period. The decrease was most pronounced during the first three months. The biggest decrease in posterior wall and interventricular septum thickness was detected by echocardiography also within the first three months. While complete regression of posterior wall hypertrophy was noted within the next three months, interventricular septum thickness decreased steadily over a period of two years. No significant change was seen in the septum in the third year of follow-up. Complete regression of hypertrophy was found in 30 (57.7%) of probands, with no change altogether observed in as few as two patients. Regression was incomplete in 20 (38.4%) obese patients with manifest hypertrophy at the start of the study. Regression of hypertrophy was not associated with left ventricular function deterioration and was observed even after vasodilator administration. There were no differences between the two groups of patients. |
