Association between Hyperhomocysteinaemia and Hypertension in Sri Lankans

This study examined the relationship between homocysteine and its metabolites, and hypertension in a cohort of Sri Lankan patients with essential hypertension. Serum homocysteine, cysteine, cysteinylglycine and glutathione were measured in 86 patients with a diagnosis of essential hypertension and compared with those of an age- and sex-matched control group. Patients with hypertension had significantly higher mean serum concentrations of homocysteine, cysteine and cysteinylglycine. The odds ratio for hypertension for those with a mean serum homocysteine concentration above 18 mumol/l was 2.8. Hyperhomocysteinaemia is a risk factor for hypertension in Sri Lankans and can lead to a threefold increase in risk.
