| Summary: | Introduction: Pre-hypertension and stage one hypertension
remains major public health problem in both developed and
developing countries. It primarily affects elastic arteries,
hence common carotid artery Intima-Media Thickness (IMT)
and Resistive Index (RI) considered an early predictor of
cerebrovascular and cardiovascular complications.
Aim: This study was aimed to assess common carotid artery IMT
and Resistive Index in pre-hypertensives and stage one hypertensive
patients and to compare the findings between both groups.
Materials and Methods: The study design was hospital based
cross sectional study and was conducted in Sri Manakula
Vinayagar Medical College and Hospital, Pondicherry. Forty
non diabetic patients in the age group of 25-65 years were
examined for carotid artery Doppler. The patients were divided
into prehypertensives and stage I hypertensives. Bilateral
common carotid artery IMT and RI were evaluated.
Results: Among the 40 patients studied, 24 patients were
prehypertensives and 16 were stage I hypertensives, 70% were
females and 30% were males. Palpitation was the commonest
presenting symptom. Mean Systolic blood pressure was
128.25±4.66 in prehypertensives and 141.25±6.44 in stage
I hypertensives. The mean IMT in both prehypertensives and
stage I hypertensives was 0.06±0.01 on either side. Mean
Resistive Index in prehypertensives was 0.73±0.08 on either
side; while that in stage I hypertensives was 0.72±0.13 on right
and 0.71±0.11 on left. However, no rise in IMT was observed
with increasing age in both the groups. On comparison both the
groups showed no significant difference in IMT and RI.
Conclusion: To conclude, both the prehypertensives and
stage I hypertensives show similar pattern of IMT and RI of the
common carotid artery. |
