Correlation between simplified treadmill score, significantly stenosed blood vessels and SYNTAX score in CAD

The purpose of this study was to determine the correlation between the simplified treadmill score (STS) and both the number of blood vessels with significant stenosis and the severity of the SYNTAX score in patients with coronary artery disease (CAD). This was an observational, cross-sectional study conducted at Dr. Soetomo General Hospital and Premier Surabaya Hospital in Indonesia from January 2011 to February 2012. The results of the analysis using the Spearman correlation showed that there was a strong positive relationship between STS and the number of blood vessels with significant stenosis (r_s=0.616 and p<0.001). Similarly, the relationship between STS and SYNTAX score obtained (r_s=0.500 and p<0.001) indicates a fairly strong positive relationship. In conclusion, there is a significant correlation between the STS as a clinical reference for estimating the probability of CAD through a weight-training test with the number of blood vessels experiencing significant stenosis.
