The purpose of this study was to evaluate the amputation-free survival rate and predictors of major adverse cardiovascular events (extracardiac and cardiac mortality, non-fatal myocardial infarction, non-fatal stroke) in patients with atherosclerotic occlusive-stenotic lesions of the femoropopliteal-tibial segment and critical ischaemia.

We analysed the results of treating a total of 122 patients with atherosclerotic lesions of the superficial femoral artery and lower limb critical ischaemia. Of these, 35 patients had no lesions of other arterial basins, 24 patients presented with a concomitant lesion of the carotid basin, 41 subjects had lesions of the coronary basin, and 22 had lesions of the coronary and carotid basins. The patients were subjected to either bypass graft operation (n=75) or endovascular intervention (n=47). The evaluated outcome measures were amputation-free survival and the frequency of major adverse cardiovascular events. The average duration of follow up amounted to 38.2±4.3 months.

The carried out multivariate logistic regression analysis demonstrated that the factors associated with lower limb amputation and the development of major adverse cardiovascular events were as follows: a concomitant lesion of the coronary (p=0.044) and coronary-carotid (p<0.05) basins, a history of endured myocardial infarction (p=0.003), a C-reactive protein level not less than 17.0 mg/l (p<0.05) and the value of the apolipoprotein B/A1 ratio above 1.0 (p=0.004).

KEY WORDS: multifocal atherosclerosis, lower limb critical ischaemia, amputation-free survival, MACE predictors, revascularization, arterial reconstruction.
