a
The ABI was not measured in three patients on both legs and was not measurable in one patient on the non-intervened side due to a leg amputation.
b
Complex intervention was defined as the use of several methods for revascularization.
c
Currently smoking or smoking in the past.
d
For Lp(a), n = 45, reference range for Lp(a) < 75 nmol/l
Abbreviations: ABI, ankle brachial index; CAD, coronary artery disease; DEB, drug eluting balloon; GFR, glomerular filtration rate; Lp(a), Lipoprotein (a); PTA, percutaneous transluminal angioplasty.
