Left ventricular ejection fraction (%) of 5 pigs per group before treatment and at 28-day follow-up after treatment of two coronary arteries with paclitaxel/resveratrol-coated balloons (3.5 × 20 mm)

Groups	Coated 3 µg/mm2	Coated 2 × 5 µg/mm2	Uncoated	p
EF before treatment (%)	42.0 ± 8.3	40.1 ± 4.4	45.4 ± 9.9	0.573
EF at 28 days (%)	39.5 ± 6.5	34.7 ± 4.3	39.0 ± 6.2	0.375
Delta EF (%)	− 2.5 ± 8.1	− 5.4 ± 7.0	− 6.4 ± 4.2	0.642

Balloons with premounted stents except 2 × 5 µg/mm² (= 2 balloons deployed in the same vessel segment, the first one with stent, the second one without stent). Delta EF is the difference from day 28 to before treatment
