Koroner arter ektazisi olan hastalarda plazma viskozitesi

Aim. Coronary artery ectasia (CAE) is defined as localized or generalized aneurysmal dilatation of the coronary arteries. Plasma viscosity is determined by various macromolecules, eg, fibrinogen, immunoglobulins, and lipoproteins. It may therefore reflect several aspects involved in cardiovascular diseases, including the effects of classic risk factors, hemostatic disturbances, and inflammation.In this study we aimed to observe plasma viscosity of the patients with coronary artery ectasy, which is a important risk factor in coronary artery disease (CAD). In our study, viscosity of the plasma has been calculated. Method. 24 coronary artery ectasy patients and 24 coronary artery disease patients have included the study. Age, sex, cardiovascular risk factors such as existence of hypertension, smoking history and previous medication have been investigated. Plasma viscosity of all patients have been measured. Results. Plasma viscosity of coronary artery disease patients group was measured as 1.19 ± 0.7 mPa·s, coronary artery ectasy patients group was measured as 1.18 ± 0.8 mPa·s. There was no statistically significant difference between two groups (p>0.05). Conclusion. However plasma viscosity is a good known cardiovascular risk factor, one can say it does not play causal role in coronary artery ectasy. As expected there is no diffrence on fibrinogen levels between the groups, this result supports our findings on the viscosity values.
