Abstract
Aim of the study was to determine the potential of Duke Treadmill Score (DTS) in prioritizing patients for coronary
angiography in a transitional country clinical setting.We analyzed 114 patients with suspected stable coronary artery disease
who underwent exercise treadmill testing, and coronary angiography in Slavonski Brod General Hospital. DTS
was calculated from treadmill test as: exercise time – (5 ST deviation in mm) – (4 exercise angina). Regarding the
score, patients were grouped into three groups of risk for coronary artery disease: low risk, medium risk, and high risk
patients. All patients underwent coronary angiography, and were grouped in accordance to the severity of the coronary
artery disease into three groups: insignificant, significant, or severe coronary artery disease. All patients scored as high
risk DTS had significant or severe coronary artery disease. Medium and low risk DTS patients had insignificant coronary
artery disease in 50%, and 90% of cases, respectively. Medium risk patients with significant or severe coronary artery
disease were significantly older, and had more frequent history of typical chest pain with higher number of episodes
per week (P<0.05), whereas there were no differences regarding gender or presence of risk factors. There were no significant
differences among medium risk patients regarding the severity of coronary artery disease in exercise time or ST deviation.
However, the presence of limiting exercise angina in medium risk patients was significantly more related with
significant and severe coronary artery disease (P<0.05). High risk DTS result showed great potential in stratifying patients
for immediate coronary angiography. This scoring system may be used in prioritizing patients for coronary
angiography in a transitional clinical setting.
