Morphological Changes of Interventricular Septum
in Longterm Follow-Up Cases
Yutaka KIMURA*1 and Isamu SUGANO, MD*2
In patients who could be followed by echocardiography for a long period,
the clinical significance of sigmoid septum and basal septal hypertrophy
including long-term changes was investigated in patients with hypertension.
The subjects were 66 patients(24 males and 42 females, mean age: 53±12
years old) who underwent repeated echocardiography, and the initial examination
and observation after long-term follow-up(mean duration of follow-up: 10.8±1.4
years) were compared. Sigmoid septum was more advanced at the time of initial
examination in the hypertensive group than in the normotensive group, but
it was similarly advanced after the long-term follow-up in both groups.
There was no significant difference in basal septal hypertrophy between
the hypertensive and normotensive groups at the time of initial examination,
but significant increases in thickening were observed in the hypertensive
group after the long-term follow-up. The above findings suggested that
morphological changes in the interventricular septum reflect the severity
of arteriosclerosis that is expected to be more advanced in hypertensive
patients than in normotensive patients.
