Slow-flow phenomenon after drug-coated balloon angioplasty for lower-extremity arteries is associated with lack of prescribing of calcium channel blockers. Indian Heart Journal. 2023 Feb; 75(1): 82-850019-48322213-3763http://imsear.searo.who.int/handle/123456789/220964This study aimed to investigate the relationship between prescription drugs and the slow-flow phenomenon after drug-coated balloon angioplasty. Of 30 patients, five (17%) presented with the slow-flow phenomenon. Patients with the slow-flow phenomenon were significantly less commonly prescribed calcium channel blockers than those without the slow-flow phenomenon (P ¼ 0.03). There was no intergroup difference in the prescription of angiotensin II receptor blockers and b-blockers. The clinical outcomes, including restenosis, thrombosis, target lesion revascularization, and death, did not differ between groups during the 10-month observation period.Slow-flow phenomenonCalcium channel blockersEndovascular treatmentVasospasmSlow-flow phenomenon after drug-coated balloon angioplasty for lower-extremity arteries is associated with lack of prescribing of calcium channel blockersJournal ArticleIndiaDepartment of Cardiology, Japan Community Healthcare Organization (JCHO) Osaka Hospital, 4-2-78, Fukushima, Fukushima-ku, Osaka, 553-0003, Japan
