Abstract

Introduction:
The
aim of this study was to determine the relationship between isolated systolic
hypertension and red blood cell distribution width (RDW).

Patients
and Methods: Eighty-one patients were included in the study. Blood
pressure was measured by a cardiologist using a manual sphygmomanometer, and
the patients were divided into 2 groups as isolated systolic hypertensive and
normotensive based on the European Society of Hypertension classification.
Complete blood counts (CBC) and biochemical values of each patient were
measured using standard methods.

Results: There was significant difference
between the mean RDW values of the isolated systolic hypertensive and the
normotensive groups. While there was a strong association between high RDW
values and isolated systolic hypertension, there were no significant differences
between the 2 groups for any of the other measured laboratory values.

Conclusion: High RDW value appears to
be a strong and independent predictor of isolated systolic hypertension.

Abstract

Giriş: Bu çalışmanın amacı, izole sistolik
hipertansiyon ve kırmızı kan hücresi dağılım genişliği (RDW) arasındaki
ilişkiyi belirlemektir.

Hastalar ve Yöntem: Toplam 81 hasta
çalışmaya dahil edildi. Kan basıncı manuel sfingomanometre kullanarak bir
kardiyolog tarafından ölçüldü ve hastalar Avrupa Hipertansiyon Topluluğu
sınıflandırmasına dayalı olarak normotansif ve izole sistolik hipertansif
olarak iki gruba ayrıldı. Tam kan sayımı ve her hastanın biyokimyasal değerleri
standart yöntemler kullanılarak ölçüldü.

Bulgular: İzole sistolik hipertansif ve
normotansif grupların ortalama RDW değerleri arasında anlamlı bir fark tespit
edildi. Yüksek RDW değerleri ve izole sistolik hipertansiyon arasında güçlü bir
ilişki varken, diğer ölçülen laboratuvar değerleri bakımından iki grup arasında
anlamlı farklılık yoktu.

Sonuç: Yüksek RDW değeri izole
sistolik hipertansiyon için güçlü ve bağımsız bir belirleyici olarak tespit
edildi.
