MedicalXpress | 三月 31, 2026

In what is believed to be the first randomized placebo-controlled trial of its kind, patients with a chronic total blockage of a coronary artery who received a nonsurgical procedure to reopen the artery showed statistically significant reductions in chest pain and improvements in quality of life compared with patients who received a placebo procedure. The research was presented at the American College of Cardiology's Annual Scientific Session (ACC.26). The study was simultaneously published online in the JACC.
