[Multivascular atherosclerosis, the Sarajevo Vascular Study].
BACKGROUND
We started with Sarajevo Vascular Study (SVS) in 1994 with basic aim to evaluate arterial occlusive disease (AOD) of lower extremities and investigate possible effect of amelioration of risk factors to atherosclerosis regression. In 1996 we expanded SVS to polyvascular atherosclerotic disease, asymptomatic or symptomatic atherosclerotic disease on various vascular beds i.e. lower extremity arterial occlusive disease (AOD), cerebrovascular disease (CVD), coronary artery disease (CAD). We enrolled a total of 1680 pts. in the study but this number has changed depending on war migrations, comorbidity, or paramedical reasons. Follow-up of 10 yrs. had 645 pts, and follow-up of 8 yrs. had 1035 pts.


METHODS
We enrolled a total of 1680 pts, 954 pts with symptomatic disease, and 246 pts without atherosclerotic disease but with at least 3/8 multiple risk factors (MRF), and as controls 400 pts without vascular disease and less than 3 MRF.


METHODS
one center, prospective, consecutive, with evaluation of epidemiological data--gender, age, comorbidity, antropometrical data, hemodynamic data--systolic and dystolic velocities, pulsatility and resistive indices, and morphologic data. Clinical variables--gender, age, hypertension, smoking, hyperlipoproteinemia, diabetes mellitus, obesity and fibrinogen. Score of MRF was calculated as x/8.


RESULTS
Out of total of 645 pts (10 yrs. follow-up) 399 pts (62%) had AOD, out of them single AOD had 295 pts (74%), and polyvascular disease 104 pts (26%). 63 (61%) pts of symptomatic group had combination of AOD + CAD, and 41 pts (39%) had AOD + CVD + CAD. In the pts with 8 yrs. follow-up (n-1035) AOD had 548 pts. (53%), single AOD had 334 pts (57%) and polyvascular had 122 pts (39%). Out of symptomatic pts. 71 (58.2%) had AOD + CAD, and 51 (41.8%) had AOD + CAD + CVD. Asymptomatic disease on the very entry period of the study was significant for both groups, p < 0.01.


CONCLUSIONS
(i) we found a significant number of asymptomatic atherosclerotic changes on other vascular beds, (ii) score of MRF has correlated with polyvascular disease and with overall outcome (iii) antropomethric, haemodynamic, and morphological parameters of human blood vessels have been measured and systematically documented in Bosnia and Herzegovina.
