Objectives: We investigated the relationship between target organ damage (TOD) and haemostatic parameters in hypertensive patients.
Methods and Materials: Fifty-five hypertensive patients and 25 healthy subjects. Were enrolled in this study after 8-10 hours of fasting haemostatic parameters; fibrinogen, fibrin D-dimer, protrombin time (PT), partial thromboplastin time (PIT), platelets, and lipid parameters (total cholesterol, HDL-cholesterol, LDL- cholesterol, triglycerides) have been studied in blood sample. To determine target organ damage, hypertensive nephropathy, hypertensive retinopathy and left ventricle hypertrophy were evaluated.
Results: In hypertensive group HDL-cholesterol levels were lower (p<0.001) and LDL-cholesterol (p<0.001) and triglyceride levels (p<0.001) were higher than healty subjects. In hypertensive group, the levels of serum fibrinogen and D-dimer were higher (p <0.001) than that of healty subjects. No signi¬ficant differences have been found in terms of platelets and PT when hypertensive patients and control groups were compared. It has been found that there is significant relationship between ha¬emostatic parameters and TOD in hypertensive patients (p<0.05). Serum fibrinogen and D-dimer levels were higher (p<0.()01) in hypertensive patients with TOD.
Conclusions: As fibrinogen and D-dimer levels were found hig¬her in hypertensive patients than healty subjects, it is considered that hypertension is related with haemostatic disorders. High le¬vels of fibrinogen and D-dimer are related with TOD.
Amaç: Hipertansif olgularda Hedef Organ Hasarı (HOH) ile hemostatik parametreler arasındaki ilişkiyi araştırdık.
Gereç ve Yöntem: Çalışmaya 55 hipertansif olgu ile 25 sağlıklı normotansif olgu alındı. Olgularda 8-10 saatlik açlık sonrası karıda hemostatik parametreler; fibrinojen, D-dimer, protrombin zamanı (PTZ), aktive edilmiş parsiyel tromhin zamanı (aPTT), tromhosit sayısı ve tipid parametreleri (total kolesterol, HDL-kolesterol, LDL-kolesterol ve trigUserid) bakıldı. HOH olarak hipertansif nefropati, hipertansif retinopati ve sol ventrikül hipertrofisi (SVH) değerlendirildi.
Bulgular: Hipertansif olgularda kontrol grubuna göre HDL-kolesterol seviyeleri diişiik (p<0.001), LDL-kolesterol (p<0.001) ve Irigliserid (TG) seviyeleri (p<().()()l) yüksek saptandı. Hipertansif olgularda serum a PTT, fibrinojen ve D-dimer düzeyleri kontrol gruplara göre anlamlı olarak yüksek (p<0.001) saptanırken, tromhosit sayısı ve PTZ açısından anlamlı farklılık saptanmadı. Hipertansif olgularda fibrinojen ve D-dimer seviyeleri retinopati, nefropati ve SVH olan olgularda olmayanlara göre istatistiksel olarak anlamlı düzeyde yüksek bulunmuştur (p<0,05).
Sonuçlar: Hipertansif olgularda a PTT, fibrinojen ve D-dimer se¬viyelerinin yüksek bulunması hipertansiyonun hemostaz bozukluğuna sebep olduğunu göstermektedir. Yüksek fibrinojen ve D-dimer seviyeleri HTda HOH ile ilişkilidir.
