Systemic @entity101 is a common cause of @entity712 . However, left ventricular (LV) systolic function remains normal for many years in @entity1 with mild or moderate @entity101 . In this study, high-quality M-mode echocardiograms were recorded in 7 @entity1 with borderline @entity101 , 14 @entity1 with mild @entity101 and 15 normal @entity1 . Measures of systolic and diastolic LV function and the degree of @entity4346 were studied with the assistance of a tablet digitizer and dedicated microcomputer. Average blood pressure was 125 +/- 10/77 +/- 7 mm Hg in normal subjects, 146 +/- 18/92 +/- 2 mm Hg in @entity1 with borderline @entity101 and 150 +/- 11/102 +/- 4 in @entity1 with mild @entity101 . Indexes of systolic LV function were similar in all 3 groups. The peak rate of early relaxation of the LV posterior wall was significantly decreased in the group of @entity1 with mild @entity101 (4.7 vs 6.6 @entity8639 , p less than 0.01). The mitral valve closure rate was 150 +/- 32 mm/s in normal subjects, 119 +/- 35 mm/s in @entity1 with borderline @entity101 and 106 +/- 26 mm/s (p less than 0.001) in @entity1 with mild @entity101 . Mild @entity4346 was present in 6 of 7 @entity1 with borderline and 13 of 14 @entity1 with mild @entity101 . The degree of @entity1184 and the level of blood pressure correlated poorly.(ABSTRACT TRUNCATED AT 250 WORDS)
