Abstract
. This study shows that early noninvasive assessment of transmitral flow velocity by Doppler echocardiography allows identification of patients at high risk for progressive LV dilation within 6 months after anterior reperfused AMI.
A restrictive filling pattern, as expressed by a short (?130 mSec.) DT of early filling is the most powerful predictor of LV remodeling, and LV dilation is related to the severity of impairment of LV filling.
Patients with restrictive MV flow pattern (DT ? 130 mSec.) had a higher level of peak serum level of CK enzyme, suggesting a larger infarction area. There was a strong correlation between DT and measures of LV systolic functions, as LVEDV, LVESV and EF. Also, there was a strong correlation between DT and E/A ratio.There was no significant difference between LV performance measures between patients reperfused medically (by thrombolysis) or by primary coronary intervention.
However, larger studies are needed to determine the prognostic implications of LV filling patterns in AMI and the role of Doppler ultrasound in this setting.
