Known IHD, CABG 2003. Recent symptoms
The resting ECG showed sinus rhythm,
LAD. During exercise there was down sloping ST segment depression
in V6 at peak stress. These changes became more positive in the
recovery period though slowly responded to O2, GTN and Aminophylline
Moderately large defect in the distal anterior wall and apex.
Rest perfusion scan (following sublingual GTN): Normal.
Gated Images: Post CABG wall motion changes in the septum with
mildly reduced septal thickening (normal>50%). Estimated LVEF
Positive ECG changes in the absence of chest pain on dipyridamole
infusion (with exercise).
The myocardial perfusion scan demonstrates
a moderately large area of inducible ischaemia in the anterior
wall and apex (LAD territory).
The resting left ventricular ejection
fraction is at lower limits of normal.
