Hematocrit level effect on diastolic blood pressure more than systolic blood pressure

Abstract

The objective of the study: is to study the effect of hematocrit (PCV) on diastolic and systolic blood pressure and assert the effect of PCV on blood pressure especially on isolated diastolic blood pressure.

Design: cross-sectional study of two groups of patients with isolated diastolic and isolated systolic hypertension and normal healthy controls.
Setting: Al- Karama teaching Hospital Department of medicine in Al- Kut city, Iraq. Patients and Method:-This cross-sectional study included inpatients and outpatients with hypertension from (February 2013 to December 2013) in Al- karama Teaching Hospital Department of medicine. The samples were divided into three groups, group 1 (normal healthy controls), group 2(patients with isolated diastolic hypertension) and group 3(patients with isolated systolic hypertension). The level of PCV was measured in each group.
Results: Patients with isolated diastolic hypertension have positive relation with increased level of PCV, frequency of patients with PCV>51% is 28% (mean 48.04), more than that in individuals with isolated systolic hypertension, frequency of PCV>51% is 16% (mean 45.70), and normal healthy controls frequency of PCV>51%
is 6% (mean PCV 41.34).
Hematocrit level remained as statistical significance for patients with isolated diastolic hypertension (P<0.0005), and also in patients with isolated systolic hypertension (Mean PCV 45.70) in compare to normal individuals (P<0.0005)
Conclusions: increased level of PCV is a risk factor or marker that affect blood pressure specially patients with isolated diastolic hypertension more than patients with isolated systolic hypertension
