"However, there has been recent evidence to show that it may be safe for patients taking long-term thyroxine replacement therapy to have a low but not suppressed TSH level. The patients who took part in the study who had very high (more than 4.0mU/l) or suppressed (less than 0.03mU/l) TSH levels more frequently suffered from heart disease, abnormal heartbeat patterns and bone fractures compared to patients with TSH levels in the normal range (0.4-4.0). Patients who had a slightly low TSH level (0.04 – 0.4mU/l) did not have an increased risk of contracting any of these conditions."
Is this saying that TSH of 0.03 or lower is bD for the heart and that TSH 0.4 do not have heart problems???
