AbstractBackground:Subclinical hypothyroidism (SH) is defined as elevated serum levels ofTSH
with normal levels of free T4 (fT4) and free T3 (fT3). The prevalence of SH has been
reported to be 4–10% in general population. Since it is generally asymptomatic, these
patients are mostly identified through routine screening or evaluation of non specific
symptoms. About 2–5% of patients progress to overt hypothyroidism annually.
Objectives: To study the mean platelet volume in patients with subclinical
hypothyroidism and to study the association between MPV and CAD in patients with
Material &Methods:We studied 89 subclinical hypothyroid subjects and estimated
theirMean platelet volume and their cardiovascular function by ECG and 2D ECHO
and then analyzed the data.
Results:MPVwas high (>11fl) in 75.3% of subclinical hypothyroid and MPV has
significant positive correlation with TSH Values. 70.8% subclinical hypothyroid
subjects had LVDD. ECG changes suggestive of IHD and RWMA in 2D ECHO was
present in 48.3% and 37.1% of the subjects respectively.
Conclusion:In our study we found that subclinical hypothyroidsubjects have significant
elevation in MPV. It is also associated with left ventricular diastolic dysfunction. Hence
it is necessary to screen and treat high risk group for subclinical hypothyroidism and its
adverseoutcomes to minimize serious complications.
