Finger Systolic Blood Pressure Index Measurement: A Useful Tool for the Evaluation of Arterial Disease in Patients With Systemic Sclerosis

Objective To evaluate the prevalence and clinical correlates of peripheral arterial disease of the upper limbs in patients with systemic sclerosis (SSc), as detected with finger brachial pressure index (FBPI) measurements. Methods This work is based on the baseline data of the SCLEROCAP multicenter cohort of SSc patients. Finger systolic blood pressure was measured with laser Doppler flowmetry, and the FBPI was obtained as its ratio over the ipsilateral brachial systolic blood pressure. An FBPI of
