Key result
Fractional flow reserve correlated moderately well with dobutamine stress echocardiography (kappa = 0.51), demonstrating 100% sensitivity and 100% negative predictive value for detecting ischemia.

Does fractional flow reserve correlate with dobutamine stress echocardiography in detecting ischemia in patients with moderately severe coronary stenosis?
Effect estimate: kappa 0.51
FFR has a high negative predictive value compared to dobutamine stress echocardiography, making it a useful tool to reliably rule out ischemia in moderately severe coronary lesions.
Jiménez‐Navarro et al. (2001) conducted an observational in Moderately severe coronary stenosis (n=21). Fractional flow reserve (FFR) vs. Dobutamine stress echocardiography was evaluated on Detection of ischemia (kappa 0.51). Fractional flow reserve correlated moderately well with dobutamine stress echocardiography (kappa = 0.51), demonstrating 100% sensitivity and 100% negative predictive value for detecting ischemia.
