Abstract
The inflammatory process causes diffuse and distal coronary disease. There are the evidences in literature datas on possible link between persistent bacterial infection with Chlamydia pneumoniae (CP) and atherosclerotic process. Besides experimental animals (mouses, rabbits) where CP was found and showed the acceleration of atherosclerosis, the seroepidemiological studies confirm higher incidency of chronical infection with CP in patients with acute myocardial infarction and unstable angina pectoris than in control group.The bactery was found in the vascular tissue of patients who died of coronary heart disease.
The mechanism of artery wall damage by CP has not been explained yet. It is possible that CP is an incidental "passenger" in atheromatotic plaque. Maybe it accounts to local inflammation in the atheromatotic artery wall. Maybe it increases koagulability of blood leading to fatal incidents in atherosclerosis. It may influence the metabolism of holesterol and the formation of foam cells.
In the prospective clinical study we want to find out whether our population of patients with diffuse and distal coronary heart disease differ in incidency of CP infection according to healthy population. The higher prevalency of chlamydial infection (as well as chronic CP infection) is expected in patients with coronary heart disease than in healthy controls. The single and cummulative role of CP will be evaluated, including other risk factors for atherosclerosis (hyperlipidaemia, arterial hypertension, diabetes, obesity, smoking). The histological and immunohistological analyses of endarterectomised sequesters of coronary artery patiets after the operation will contribute to eventually clearify the reason for the artery wall damage.
The diagnostic screening of our patients and the subsequent antibiotic therapy of serological determined infection of CP will hopefully lead to better treatment of coronary heart disease.
