Effect of Subclinical Hyperthyroidsm on the Outcome of Coronary Artery Graft Bypass Surgery

Year 2018, Volume: 5 Issue: 3, 80 - 83, 28.09.2018

Abstract


Introduction:
Subclinical hyperthyroidsm is associated with negative effects on
cardiovascular system. We aimed to evaluate the association between
pre-operative thyroid hormones and post-operative outcome in patients
undergoing coronary artery by-pass graft (CABG) surgery.


Methods:
A hundred and eighty nine patients with isolated CABG surgery were
included into the study. Patient’s clinical characteristics,
surgical details and post-operative mortality and morbidities were
recorded.Patients were divided into two groups according to their TSH
level with cut-off point of 0,35 was assumed.


Results:
The first group consists of 16 patients (9%) with subclinical
hyperthyroid (SH) and the second group includes 173 euthyroid
patients. In post-operative period; the incidence of arrhythmia,
renal failure and inotropy requirement were significantly higher in
SH group (p<.0001, p: 0.0002 and p<.0001 respectively)


The incidence of
peri-operative mortality was similar between groups. (p: 0.0860).


Lenght of stay in
intesive care unit and overall were significantly higher in patients
with SH (p:

0.0102
and p: 0.0004 respectively).







Discussion and
Conclusion:

Pre-operative subclinical hyperthyroidsm didn’t effect
peri-operative mortality but may lead to higher postoperative
complications such as arrhythmia, renal failure and low cardiacoutput
syndrome in patients undergoing CABG surgery.
