Improved quality of life after 1 year with an invasive versus a noninvasive treatment strategy in claudicants: one-year results of the Invasive Revascularization Or Not in Intermittent Claudication (IRONIC) Trial. Circulation 2014; 130: 939-947.

Published: 20th May 2015

Authors: Nordanstig J, Taft C, Hensäter M, Perlander A, Osterberg K, Jivegård L et al.

Conclusion

A total of 158 patients were included in the trial. Claudication distance improved in the invasive treatment group (+124m versus +50m in the noninvasive group; P=0.003), as did quality of life using a number of scoring methods (all P<0.01).
