We evaluated the left ventricular mass index (LVMI) and the functional response to cold pressor and handgrip tests in 74 untreated essential hypertensive patients and 26 age and sex-matched normals. The same measurements were repeated in 22 essential hypertensives after 6 and 12 months of treatment (captopril or nitrendipine, plus diuretic or (3-blocker in a few cases) and in 21 essential hypertensives after withdrawal of treatment, a reduction in the LVMI and a further increase in blood pressure. Left ventricular systolic function was evaluated by the relationship between left ventricular end-systolic stress and fractional shortening. Highly significant negative correlations, with similar slopes and intercepts, were found between end-systolic stress and fractional shortening under basal conditions, after regression of left ventricular hypertrophy and after withdrawal of treatment, both at rest and at the peak of stress tests. An examination of each point of the relation between end-systolic.stress and fractional shortening showed that very few points were beyond the 95% prediction limits of the correlation obtained in normal volunteers. These results indicate that left ventricular systolic function is normal in most untreated essential hypertensives, and is usually well maintained after regression of left ventricular hypertrophy during longterm treatment as well as after withdrawal of treatment, both at rest and during an acutely induced afterload increase.
