Abstract:
Hypertension is the force of blood pushing up against the walls of blood vessels and it is defined
as a systolic blood pressure ≥ 140 mm Hg and diastolic blood pressure ≥ 90 mm Hg, it is the
leading risk factor for global disease burden. The objective of this study was to identify risk
factors of mortality among hypertension patients in UOGCSH, Gondar in Amhara Regional
State, northwest Ethiopia. The purpose of this study was to identify factors that affect the
survival time of hypertension. Among 1921 hypertensive patients who were followed in
UOGCSH during January 2014 to January 2019 were selected 308 hypertensive patients. The
sampling methods used were systematic random sampling method. To determine factors that
affect the survival time of hypertension, compare the survival time as well as examine the
association between the survival time with different demographic and clinical categorical
variables, the Kaplan Meier estimation method and the Cox proportional regression model were
applied. The descriptive analysis showed that out of 308 patients, 65 (21%) patients died during
the follow up period. From the total sample 177(57.47%) were females and 131(42.53%) were
males and among their age groups 96(31.17%) were age18-40, 134(43.51%) were age 41-59 and
78(25.32%) were age ≥60 years. The Log rank result also indicates that the survival time of
hypertensive patients are not statistically different in experiencing the death event among group
classified by sex. The results of the multivariable PH Cox regression analysis showed that age of
patient, cholesterol level, smoking status, world health organization (WHO), hypertension stage
and diabetic mellitus status were statistically significant to the death of hypertension. The
findings of this study show that age, cholesterol level, smoking status, stage of hypertension and
diabetic mellitus status were the factors that affect the survival time of hypertensive patients.
