Mid-term outcomes of patients with subclinical hypothyroidism after coronary bypass surgery.

ABSTRACT:

Objectives

Subclinical hypothyroidism (SCH) is characterized by an elevated thyroid-stimulating hormone and normal free thyroxine. This study aimed to evaluate the influence of SCH on mid-term outcomes of patients after coronary artery bypass grafting (CABG).

Methods

From January 2015 to December 2018, 548 SCH patients and 6718 euthyroid patients who underwent CABG were identified. Propensity score matching was used to create 2 cohorts with similar baseline characteristics (n = 544 in each group). The mid-term follow-up outcomes were compared. Adjusted hazard ratios (HRs) were calculated using Cox proportional hazards models.

Results

The mean follow-up for all patients was 39.7 ± 17.3 months. The unadjusted Kaplan-Meier estimate for mortality at 5-year follow-up was h
