Key result
Systolic time interval measurements (Δ PEP and PEP/LVET ratio) showed a strong correlation (r=0.75) with the serum free T4 index across the entire range of thyroid function.
Why the study?
Do systolic time intervals correlate with thyroid function in patients with varying thyroid states?
Observational (n=49)
Do systolic time intervals correlate with thyroid function in patients with varying thyroid states?
Effect estimate: r = 0.75
Systolic time intervals correlate significantly with serum free T4 index, providing a valuable non-invasive tool to assess cardiac response to thyroid hormone levels.
No takes yet. Share an insight, caveat, or question.
Systolic time intervals may track cardiac thyroid effects non-invasively; leaves open clinical utility pending prospective validation.
Paulus et al. (1980) conducted an observational in Hyperthyroidism, euthyroidism, or hypothyroidism (n=49). Thyroid function (serum free T4 index) was evaluated on Correlation between systolic time intervals (Δ PEP, PEP/LVET ratio) and serum free T4 index (r = 0.75). Systolic time interval measurements (Δ PEP and PEP/LVET ratio) showed a strong correlation (r=0.75) with the serum free T4 index across the entire range of thyroid function.
