Introduction: The etiological and pathogenic factors responsible for coronary artery ectasia (CAE) are unclear. Therefore, we aimed to compare subjects with and without CAE with respect to resistin levels and determine whether resistin plays a role in the aetiology or pathogenesis of CAE.
Patients and Methods:This study enrolled a total of 81 subjects, of whom 42 had CAE [15 female (F), mean age 60.4 ± 9.0 years] and 39 had a normal coronary anatomy (22 F, mean age 56.2 ± 10.7 years). Using coronary artery diameters of the control group as reference, subjects having coronary artery dilatation that was at least 1.5 times larger than the normal adjacent segments were considered to have CAE. Resistin levels were measured from blood samples obtained on the day of the coronary angiography. Sonuç: KAE ve aterosklerozis ortak histopatolojik ve klinik özellikler arz etmektedir. Resistin, aterosklerozun gelişiminde ve klinik tablonun oluşumundaki yeri iyi bilinen bir polipeptid olup, aynı zamanda KAE oluşu-munda da rol alıyor olabilir. Resistinin KAE'nin oluşumunda ki yerinin daha iyi anlaşılabilmesi için büyük ölçekli çalışmalara ihtiyaç duyulmaktadır.
