Cardiac death risk in diabetic haemodialysis patients increased
due to thyroid problems
A prospective study found that diabetic haemodialysis patients’
subclinical hyperthyroidism and euthyroid sick syndrome might
increase the risk of sudden cardiac-related deaths. Dr Christiane
Drechsler, of University Hospital Würzburg in Würzburg,
Germany, and colleagues conducted a study that included 1 000
patients undergoing haemodialysis for diabetes. Of those patients,
78.1% had euthyroidism, 13.7% had subclinical hyperthyroidism,
1.6% had subclinical hypothyroidism and 5.4% had euthyroid
sick syndrome.
Patients with euthyroidismwere compared with those who had
subclinical hyperthyroidism and euthyroid sick syndrome, with
regard to which group showed an increased short-term (within
a 12-month period) risk of sudden cardiac death. It showed
that patients who had euthyroidism had a 2.0-times increased
short-term risk of sudden cardiac death, and those who had
subclinical hyperthyroidism and euthyroid sick syndrome had a
2.7-fold increase.
The results showed that euthyroid sick syndrome was
associatedwith a three-fold increased risk of short-termmortality,
but in the long term (two to four years) it showed no increased
risk. The study revealed that subclinical hypothyroidism was
not associated with cardiovascular events or all-cause mortality,
which revealed thyroid disorders had no influence on the risks of
myocardial infarction and stroke.
This study led researchers to conclude, ‘Regularly assessing a patient’s thyroid
status may help estimate the cardiac risk of dialysis patients.’
