A study of hyperinsulinaemia in Indian hypertensive subjects.

Fasting and 2 hours post-prandial serum insulin levels were estimated in 100 hypertensive subjects and 25 matched, healthy controls, by radio-immuno assay (RIA). Seventy four of the 100 hypertensives exhibited fasting hyperinsulinaemia. Post-prandial hyperinsulinaemia was present in 85 hypertensives. None of the healthy individuals demonstrated hyperinsulinaemia. Although, most hyperinsulinaemic patients exhibited an abnormal lipo-protein profile, there was no statistical correlation between absolute values of lipo-protein and insulin.
