Abstract

ABSTRACT:
BACKGROUND:
Ischemic heart disease induce changes in myocardial performance and there are different ways to study this performance as using echocardiography and cornary angiogram
OBJECTIVE:
Correlate the findings of regional wall motion abnormalities assessed by 2D echocardiography, to the coronary artery lesions detected by coronary angiogram.
METHODS:
This study included 101 patients who attended the Iraqi Center of Heart Disease between March 2010 and April 2011. In addition to routine investigations, echocardiography and coronary angiography were done to them.Patients were grouped according to segments of regional wall motion abnormalities into 3 groups :group A (segments 1,2,7,8,13,14), group B (segments 3,4,9,10,15), and group C (segments 5,6,11,12,13,16).These groups were correlated according to the score of regional wall motion abnormalities, with each coronary artery lesions detected by coronary angiogram.
RESULTS :
(47.5%) of patients in group(A) had hypokinesia, Akinesia in (14.9%), and dykinesia in (21.8%), majority of these abnormalities were correlated with LAD lesions (P-value 0.0001).(44.4%) of patients in group(B) had regional wall motion abnormality in form of hypokinesia(35.6%), akinesia(7.9%), and dyskinesia(1%) .There was a strong correlation between group(B) and LCX lesions (P-value=0.0001)
(27.8%) of patients in group(C) showed hypokinesia ,(5% ) Akinesia, and (8 % ) dyskinesia ,majority were associated with RCA lesions in form of critical and total occlusions.
CONCLUSION:
Regional wall motion abnormalities detected by 2D-echocardiography can be correlated with the lesions of the affected coronary vessel, in terms of the site and severity.
