Purpose:
To determine the incidence of atherosclerotic coronary artery disease (CAD) and or myocardial ischemia in patients (pt) with abnormal ST segments restrict to recovery phase (RRAST) of exercise testing (ET).
Material And Method:
Retrospective study in 19 non consecutive pt with RRAST, related to coronary arteriography or exercise planar scyntillography (18 men, 58 +/- 9 years, 18 asymptomatic).
Results:
RRAST corresponded to ST segment depression from 1 to 4 mm, with T inversion during early recovery (2 pt); late (14 pt) or both (4 pt). It was documented CAD (14 pt and 9) with artery-by-pass surgery); hypertensive myocardiopathy with normal coronary (3 pt), and mitral prolapse valve (1 pt). In 13 pt with coronary arteriography or exercise scyntillography, within the first 6 months from exercise testing, myocardial ischemia was confirmed in 8 pt in 3 pt, successive exercise testing showed RRAST reproductive in 2 cases.
Conclusion:
The authors report the high incidence of CAD and or transitory hypoperfusion during myocardial scyntillography in symptomatic men with middle age with RRAST during exercise testing.
