METHODSNO was analyzed colorimetrically in 30 newly diag-nosed hypothyroid postmenopausal females and 30 postmenopausal females with normal thyroid profle. Results were compared and subjected to appropriate statistical analysis. RESULTSThe levels of serum NO were found to be significantlydecreased in postmenopausal females with hypothyroidismas compared to the levels in those with normal thyroidprofile （P value 〈 0.05）. A negative correlation of NOwas observed with thyroid stimulating hormone whereasa positive correlation of NO was observed with free T3 （FT3）, free T4 （FT4）, T3 and T4 though it was statistically signifcant only for FT4 among postmenopausal females with hypothyroidism.CONCLUSIONPostmenopausal hypothyroid females may be at a risk of compromised cardiovascular health as indicated by low NO levels. Regular monitoring and risk assessment is essential for timely intervention.展开更多
