An open label, single-centre, randomized trial of spinal cord stimulation vs. percutaneous myocardial laser revascularization in patients with refractory angina pectoris: the SPiRiT trial

摘要

McNab et at.'are to be congratulated to have performed the first randomized controlled trial (RCT) to compare percutaneous myocardial laser revascularization (PMR) with spinal cord stimulation (SCS). The results are encouraging and confirm previous results on both- therapy modalities.In the introduction, they have mentioned the many techniques for patients with refractory angina. They have stated that there is little evidence directly comparing these multiple therapeutic modalities, not mentioning the RCT performed by Tio et at. to compare PMR with vascular endotheliaE growth factor.We would like to draw the attention to the introduction, where they have stated that SCS is supported by one RCT, however, at the end of the next paragraph they refer to another RCT of SCS, which is one of several RCT's to support SCS.
