Key result
DSCT without beta-blockers shows similar coronary stenosis diagnostic accuracy regardless of heart rate.
Why the study?
Does a higher heart rate (≥65 beats/min) reduce the diagnostic accuracy of dual-source computed tomography coronary angiography compared to lower heart rates (<65 beats/min) in patients without beta-blocker pre-medication?

Dual-source CT coronary angiography maintains high diagnostic accuracy for detecting coronary stenoses even at higher heart rates (≥65 bpm) without the need for beta-blocker premedication.

Dual-source CT coronary angiography maintains high diagnostic accuracy for detecting coronary stenoses even at higher heart rates (≥65 bpm) without the need for beta-blocker premedication.
Ropers et al. (2007) conducted an observational in Coronary artery stenoses (n=100). Heart rate ≥65 beats/min vs. Heart rate <65 beats/min was evaluated on Overall diagnostic accuracy on a per-patient basis (p=NS). Dual-source computed tomography without beta-blockers yielded similar overall diagnostic accuracy for coronary stenoses in patients with heart rates ≥65 vs <65 beats/min (91% vs 86%).
