Impact of Thyroid Disorders on Clinical Parameters of Subjects Undergoing Coronary Artery Bypass Grafting

Abstract

The heart and the thyroid gland are two of the most vital organs of the human body. Optimum functioning of these two organs is essential for the wellbeing of the body. These two organs share a twin-way relationship. Mild deviation from the normal range of thyroid hormone levels affects the heart. Hence, thyroid disorders (TD) are suspected to be strongly associated with the cardiovascular diseases (CVD), especially in cases undergoing a coronary artery bypass grafting (CABG). Usually thyroid disorders pose very subtle symptoms which go un-noticed and remain undiagnosed for a long period of time. In this study we analyse the effect of thyroid disorder (hypothyroid and hyperthyroid) on the clinical vitals, pre-operative, intraoperative and post-operative parameters of the subjects who had undergone CABG. Our analysis establishes that thyroid disorders, if not controlled, can be indicators of poor outcomes in subjects undergoing CABG. Regular monitoring and maintenance of thyroid hormones is imperative in subjects undergoing CABG.
