Key result
Thyroid dysfunction altered systolic time intervals, with PEPc and PEP/LVET ratios significantly decreased in thyrotoxicosis (p<0.01) and increased in hypothyroidism (p<0.001) versus euthyroid states.
Why the study?
Do systolic time intervals reflect changes in myocardial contractility in patients with thyroid dysfunction before and after achieving a euthyroid state?
Observational (n=20)
Do systolic time intervals reflect changes in myocardial contractility in patients with thyroid dysfunction before and after achieving a euthyroid state?
p-value: p=<0.01
Systolic time intervals demonstrate increased myocardial contractility in thyrotoxicosis and reduced contractility in hypothyroidism, which normalize upon achieving a euthyroid state.
No takes yet. Share an insight, caveat, or question.
Systolic time intervals may track reversible contractility shifts in thyroid dysfunction; leaves open their added clinical value beyond thyroid function tests.
Lien et al. (1982) conducted an observational in Thyroid dysfunction (n=20). Thyroid dysfunction (thyrotoxicosis and hypothyroidism) vs. Euthyroid state (post-therapy) was evaluated on PEPc intervals and PEP/LVET ratios (p=<0.01). Thyroid dysfunction altered systolic time intervals, with PEPc and PEP/LVET ratios significantly decreased in thyrotoxicosis (p<0.01) and increased in hypothyroidism (p<0.001) versus euthyroid states.
