Key result
In patients with low TIMI-risk chest pain, CT coronary angiography demonstrated 100% sensitivity (95% CI 72-100%) and 80% specificity (95% CI 28-100%) for identifying significant coronary disease.

Absolute Event Rate: 100% vs 80%
16-slice CT coronary angiography is a practical, safe, and highly sensitive modality for evaluating acute chest pain in patients with low TIMI risk scores.
Soon et al. (2007) conducted an observational in acute chest pain with low TIMI risk scores (n=34). CT coronary angiography (CT-CA) vs. selective coronary angiography was evaluated on sensitivity and specificity of CT-CA in identifying patients with significant coronary artery disease. In patients with low TIMI-risk chest pain, CT coronary angiography demonstrated 100% sensitivity (95% CI 72-100%) and 80% specificity (95% CI 28-100%) for identifying significant coronary disease.
