Abstract

High pulse pressure is an important cardiovascular risk factor and it results in adaptation failure in great arteries. Pulse wave velocity (PWV) is low in the vessels which have a good compliance. in this study; the importance of carotis-femoral PWV is stressed in the patients with essential hypertension. Two groups; 50 essential hypertensive patients mean age 52.3 ±9.7 years and 20 normotensive control patients mean age 52.1 ±10.8 years were enroled to this study. The Complior system is used for determining PWV. This system is composed of a Complior PC card inserted into the IBM APTIVA. it consists of two acoustic sensors perceiving pulse wave signals and a pedal which collects data. The sensitivity of acoustic sensors placed on the carotis and the femoral is 25 mV/ mmHg, their band penetration is 0.03-300 Hz and inner impedance 100 Kohm. in the Complior system the measurement results are listed on the screen. From these results the suitable measurement is picked up according to the time interval and mean velocity. in our study there wasn 't any statistically meaningful difference between the groups with regard to their age, body-mass index and waist-limp ratio (p=0.9, p=0.5, p=0,8). Systolic and diastolic blood pressures and PWV were significantly higher in essentially hypertensive patients (p<0.0001, p<0.0001, p<0.0001). There was positive correlation between PWV and age (p=0.002), waist-limp ratio (p=0.04) and systolic blood pressures (p=0.0002). in conclusion, in patients with essential hypertension who are under risk of cardiovascular disease, the PWV could be determined by non-invasive methods easily.

Özet

Yüksek nabız basıncı önemli bir kardiyovasküler risk f aktörüdür ve esas olarak büyük arterlerde uyum azalmasıyla sonuçlanır. Kompliyansı iyi olan damarlarda nabız dalga hızı (NDH) düşüktür. Bu çalışmada esansiyel hipertansiyonlu hastalarda karotis-femoral NDH'nın önemi vurgulanmak istenmiştir. Çalışmaya yaş ortalamaları 52.3 ±9.7 yıl olan 50 esansiyel hipertansiyon hastası ve yaş ortalamaları 52.1 + 10.8 yıl olan 20 normotansif kontrol grubu alınmış olup NDH ölçümleri karotis-femoral arterler kullanılarak Complior cihazı ile yapılmıştır. Complior sistemi IBM APTIVA içerisine konulmuş bir Complior PC kartından oluşmuştur. Kapsamındaki iki akustik sensör nabız dalga sinyallerini algılarken bir pedal da veri alımını sağlar. Karotis ve femoral arterler üzerine yerleştirilen akustik sensörlerin duyarlılığı 25 m V/ mmHg, bant geçirgenliği 0,03-300 Hz, iç empedansı 100 Kohm 'dur. Complior sisteminde ölçüm sonuçları, ölçüm sonuçları ekranında liste halinde sunulur. Bu sonuçlardan zaman aralığı ve ortalama hızı hesaplamak için kullanılacak ölçüm seçilir. Çalışmamızda gruplar arasında yaş, vücut-kitle indeksi ve bel-kalça oranı açısından istatistiksel olarak anlamlı bir fark yoktu (sırası ile p=0.9, p=0.5, p=0.8). Sistolik ve diyastolik kan basınçları ile NDH esansiyel hipertansiyonlu hastalarda anlamlı olarak yüksekti (sırası ile p<0.0001, p<0.0001, p<0.0001). NDH ile yaş (p=0.002), bel-kalça oranı (p=0.04) ve sistolik kan basıncı (p=0.0002) arasında pozitif ilişki tesbit edildi. Sonuç olarak non- invaziv metodlarla rahatlıkla ölçülebilen NDH esansiyel hipertansiyonlu hastaların kardiyovasküler riskler açısından takibinde kolay ve uygulanabilir bir yöntem olabilir
