Abstract |
Myocardial scintigraphy is a widely used noninvasive
procedure with high sensitivity for the detection of
patients with suspected coronary artery disease. The
purpose of this study was to determine the prognostic
value of a normal myocardial scintigraphy in 292
patients (150 males, 142 females, mean age 53¡¾12
years) with chest pain who were followed from 7 to 58
(mean 25) months. Myocardial SPECT was performed with
Tc-99m MIBI in 173 patients, with Tc-99m tetrofosmin in
74 patients and with T1-201 in 45 patients. During the
follow-up period, there were 2 cardiac deaths and 2
nonfatal myocardial infarctions resulting in cardiac
event rate of 1.37% (0.66% per year). The cardiac event
rate was not different in patients with
angiographically normal coronary arteries (1/30, 3.3%)
and in those who had significant coronary a disease
(2/27, 7.4%) (p=0.60). In conclusion, patients with
chest pain and normal myocardial scintigraphy have a
low cardiac event rate, and there was no significant
difference of cardiac event rates between patients with
normal and abnormal coronary angiograms. |
