Pilot study of bisoprolol 8mg transdermal patch at bedtime before coronary computed tomography angiography.

Coronary computed tomography angiography (CCTA) is recommended for first-line evaluation of stable coronary artery disease, and there is a standard protocol to control heart rate (HR) in guidelines. However, time is required to decrease HR to the recommended ≤60 beats per minute (bpm). We investigated whether the bisoprolol 8mg transdermal patch at bedtime on the day before CCTA can achieve a target HR and simplify the CCTA process. We randomly assigned 63 patients with an HR of ≥70 bpm and systolic blood pressure ≥120mmHg to a standard protocol group (n=33) or a group (n=30) that applied a bisoprolol 8mg transdermal patch (Bis) at bedtime on the day before CCTA evaluation. The primary endpoint was a change in HR between enrollment in the study and the time of CCTA evaluation. The secondary endpoints were elapsed time from arrival at the CCTA suite to starting CCTA image acquisition, and the rates of oral metoprolol and intravenous landiolol administration (UMIN00035246). Baseline characteristics did not significantly differ between two groups. HR was significantly lower upon arrival at the CCTA suite in Bis, than standard protocol group (67.5±7.8 bpm vs. 75.0±10.6 bpm; p=0.00002), and the amount of elapsed time from arrival to the start of CCTA evaluation was also significantly decreased in Bis group (76.9±34.9min vs. 94.8±29.2min; p=0.0356). Rates of oral metoprolol and intravenous landiolol administration did not significantly differ between two groups (63.3% vs. 83.3%, p=0.143 and 36.7% vs. 60.0%, p=0.12, respectively). The bisoprolol 8mg transdermal patch lowered HR and decreased the amount of time needed for CCTA, thus streamlining the evaluation process. Copyright © 2019 Japanese College of Cardiology.
