Abstract (2. Language): 
Disorders of the vessels, that cause organ demage in Essential Hypertension (HT), may returned at early stage. In this study, vascular disorders were evaluated in 225HT patients with a mean age of 48.1±8.6(%77.3 of them mild and moderate hypertensive) and in 114 healthy subjects with a mean age of 46.5±8.2 years. Their systolic and diastolic blood pressure (SBP and DBP) were found J60±14, 100±8 and 119±8, 78±5 mmHg. In HT group, body mass index (BMI), fasting blood sugar (FBS), fibrinogen, von Willebrand Factor, activated platelet aggregation with adenosine diphosphate and epinephrine, lipoprotein (a)-(Lp(a)), triglyceride (TG), Uric acid (UA) values were found to be higher than those in control group. Hypertensive retinopathy was observed in the 58 % of the patients. In healthy controls SBP, DBP, and in both groups Hb, serum creatinin, TG, UA values of the males were found to be higher than those in female groups. Age and BMI were not significant different between the groups. Hb, UA, TG, Lp(a) were found higher in smokers than those in nonsmokers, in the patients group. Pozitive correlation between vascular markers and blood pressure, age of patient, duration, smoking and between FBS and obesity were observed. Serum Na* value was decreased with diatery Na+ restriction. Our findings suggest that vascular changes occur at early stage ofHT, especially male gender, smokers have high risk and obesity has additional effect for its.

Abstract (Original Language): 
Esansiyel Hipertansiyon (HT) sonucu organ hastalıklarına yol açan vasküler bozulma, erken evrede belirlenebilmektedir. Çalışmamızda, yaş ortalaması 48.1±8.6yıl, sistolikve diyastolikkan basıncı (SKBve DKB) değerleri 160±14 ve 100±8 mmHg olan 225 HTlu olgu (%77.3'ü hafif, orta dereceli) ile yaş ortalaması 46.5±8.2yıl, SKB ve DKB değerleri 119±8 ve 78±5 mmHg olan 114 sağlıklı bireyde, vasküler fonksiyon göstergeleri incelendi. Kontrol grubuna göre yaş ve cinsi farksız olan HT grubunda, vücut kitle indeksi (VKİ) ve von Willebrand Faktör, fıbrinojen, adenozin difosfat ve epinefrin ile uyarılmış trombosit agregasyonları, lipoprotein (a)-(Lp(a)), trigliserid (TG), ürik asit (ÜA), açlık kan şekerinde (AKŞ) anlamlı artış ve %58 oranında hipertansif retinopati ile vasküler etkilenme oluştuğu gözlendi. Kadınlara göre, hasta ve kontrol grup hemoglobin (Hb), serum kreatinin, TG, ÜA ve sağlıklı grup SKB, DKB değerleri Erkekler de yüksek bulundu. Sigara içen hastalarda, içmeyenlere göre yaş ve VKİ farksız, Hb, ÜA, Lp(a) da anlamlı, TG düzeyinde anlamlı olmayan artış gözlendi. Vasküler göstergeler ile kan basınçları, hasta yaşı, HT süresi, sigara ve AKŞ ile obezite arasında pozitif ilişki bulundu. Diyetle tuz kısıtlanan hastalarda serum sodyumunda anlamlı düşme gözlendi. Çalışmamızda, HT'un erken evresinde vasküler bozulmanın oluştuğunu, erkek cins ile sigara içenlerin etkilenmeye daha yatkın ve obezitenin bozulmayla ilişkili olduğunu gözledik.
