A Study to Determine Whether a Relationship Exists between High Urea Nitrogen Retention and a High Arterial Diastolic Blood Pressure
Statement of the Problem:
The problem in this study was to determine if a relationship exists between high urea nitrogen retention and a high arterial diastolic blood pressure or diseases that are usually associated with a high arterial diastolic blood pressure.
Method of Study:
The descriptive survey method was used. Data for this study were obtained by reviewing charts of all patients whose NPN was 150 mg. percent or over or whose BUN was 100 mg. percent or over. During the specified two year period the White Memorial Clinical Laboratory records revealed thirty-five patients as falling into this category.
Summary of Findings:
Twenty-nine patients, or over 80 percent, had diseases that are usually associated with a high arterial diastolic blood pressure. Eighteen of these twenty-nine were found to have an elevated diastolic blood pressure. Three of the patients had diseases not usually associated with a high arterial diastolic blood pressure and three had an undiagnosed renal disease. None of these six patients showed an elevated diastolic blood pressure.
There were sixteen patients under the age of sixty years and nineteen over this age. Those in the younger age group (under sixty years) were found to have a 75 percent incidence of a high diastolic blood pressure. Those over sixty years of age had a 31.5 percent incidence.
Twenty-two patients had a primary renal disease, half of which showed an elevated diastolic blood pressure. The incidence of a high diastolic blood pressure was relatively low in patients with pyelonephritis and high in patients with glomerulonephritis.
There were nine obstructive lesions of the urinary tract seven of which were malignancies. Fifty-five percent showed an elevated diastolic blood pressure.
Eighty percent of the patients died sometime within the specified two year period. Twenty-two died within one year of onset of their symptoms.
The findings of this study support the hypothesis that there is a relationship between a high level of urea nitrogen retention and a high arterial diastolic blood pressure or diseases that are usually associated with a high arterial diastolic blood pressure.
