Abstract

Objective: Endothelial dysfunction is now recognized as an early, perhaps initiating event in the pathogenesis of cardiovascular diseases. The purpose of the present study was to examine the influence of cardiac risk factors on endothelial function in essential hypertension (EH). Material and methods: Young 129 (53 males, mean age 45.0±6.4) mild hypertensive patients and same number of healthy controls were selected. All patients were under antihypertensive treatment for a mean duration of 44±63 months, and were at the targeted blood pressure. Major risk factors for cardiovascular diseases according to the National Cholesterol Education Program criteria and some other risk factors were evaluated. Seventy-eight EH patients and 78 age and sex matched control subjects were assessed for endothelial function using brachial artery ultrasound. Endothelium dependent (EDD) and independent (EID) vasodilation were evaluated.Results: Patients with EH were older with female dominance, had higher frequency of diabetes, obesity, higher cholesterol, triglycerides, and fibrinogen levels. EH patients had significantly impaired EDD (17.4±7.2% vs 20.7±5.8%, p=0.002) and EID (20.9±8.2% vs 24.4±6.8%, p=0.004) compared with controls. In multiple regression test only uric acid levels, presence of EH, and body mass index (BMI) were retained as significant for EDD. Only uric acid, hemoglobin levels, presence of EH, and BMI were significantly associated with EID.Conclusion: It was concluded that endothelial dysfunction was present in EH group despite optimal medical therapy. The factors analyzed in the study explain only a fraction of the variability in EDD but were intimately related to metabolic syndrome which may be one of the reasons why endothelial dysfunction was present in EH despite medical therapy.

Özet

Amaç: Endotel disfonksiyonu, patogenezinde erken dönemde saptandığı kardiyovasküler hastalıkları belki de başlatan bir olaydır. Bu çalışmanın amacı, kardiyovasküler risk faktörlerinin esansiyel hipertansiyon (EH) hastalarında endotel fonksiyona etkisini değerlendirmekti. Gereç ve yöntem: Evre I 129 (53 erkek, ortalama yaş 45,0±6,4) hipertansif hasta ve aynı sayıda sağlıklı kontrol çalışmaya alındı. Hastalar ortalama 44±63 aydır tedavi altındaydı ve hedef kan basıncına ulaşılmıştı. Ulusal kolesterol eğitim programı kriterlerine göre major risk faktörleri ve bazı diğer risk faktörleri değerlendirildi. Brakiyel arter ultrasonografisi ile 78 yaş ve cinsiyeti eşleştirilmiş kontrol ve EH hastasının endotel fonksiyonu incelendi. Endotele bağımlı (EDD) ve endotelden bağımsız (EID) vazodilatasyon değerlendirildi.Bulgular: Hastalar daha yaşlı idi, kadın hastalar çoğunluktaydı, hasta grubunda diabetes, obezite, yüksek kolesterol, trigliserid ve fibrinojen düzeyleri daha sık idi. Hipertansiflerde EDD (%17,4±7,2 karşın %20,7±5,8, p=0,002) ve EID (%20,9 ± 8,2 karşın %24,4 ± 6,8, p=0,004) kontrol grubuna göre anlamlı olarak azalmıştı.. Multipl regresyon analizinde EDD için ürik asit, EH varlığı, vücut kitle indeksi (VKİ), EID için ise ürik asit, hemoglobin düzeyi, EH varlığı ve VKİ öngördürücü bulundu.Sonuç: Optimal tıbbi tedaviye rağmen EH grubunda endotel disfonksiyonu saptandı. Çalışmamızda değerlendirilen faktörler EDD'ki değişkenliğin ancak küçük bir bölümünü açıklayabildi, bu faktörlerin bazıları metabolik sendromun komponentleri idi. Bu durum EH'da optimal tıbbi tedaviye rağmen süregelen endotel disfonksiyonun nedenlerinden birisi olabilir.
