Echo- and radionucleid-ventriculographical study on the change of dimention and the regional dysfunction of left ventricle in patients with old myocardial infarction

ABSTRACT

35 cases of OMI (with an average of 12 months after acute MI) and 44 control subjects were studied by echo- and radionucleidoventriculography. Results shown a larger dilatation of the left ventricle of OMI patients in comparing with the controls. 81.1% of OMI patients had heart wall movement disorders and their location identified by echo was consistent with the MI location diagnosed by ECG. There is a positive proportional relation between WMSI and the severity of heart failure.
