Introduction:
Cardiovascular disease, induced mainly by atherosclerosis, is the leading global cause of morbidity and mortality. Atherosclerosis develops in early childhood and coronary artery atherosclerosis can be found in about 50% of young people. As a result a great deal of effort is made to detect and identify people at increased risk of cardiovascular complications. Implementing preventive principles can prevent disease progression and the development of complications. Subclinical atherosclerosis is an early stage of the disease with only minor lesions in coronary arteries. Strong evidence supports the association between subclinical atherosclerosis and increased risk of coronary artery disease, fatal and non-fatal myocardial infarction as well as symptomatic angina. The aim of the study was to investigate the medium-term outcomes of patients with early-stage coronary atherosclerosis.

Material and methods:
From the initial group of patients with early-stage coronary artery disease (n = 45; 100%), in which coronary angiography showed no or only minor atherosclerotic lesions and in which the coronary artery calcium score assessed with 64-raw multislice computed tomography was positive (CACS > 0), 29 persons (64.5%) were enrolled in the study.

Results:
In the analyzed group of patients, satisfactory general prognosis was found. There were no cardiovascular deaths or serious non-fatal cardiovascular events. In addition, a high level of compliance, regular use of recommended treatment and satisfactory control of comorbidities and risk factors during the 48-month follow-up were observed in the studied patients. Improvement in the advancement of angina symptoms was also seen.

Conclusions:
The subpopulation of patients with early-stage coronary artery disease is burdened with moderate cardio-vascular risk in an intermediate term observation.
