LIHFA: Liothyronine and Heart Failure. The Long Term Effect of Liothyronine on Left Ventricular Ejection Fraction (LVEF)
Study Details
Study Description
Brief Summary
Purpose: The purpose of the study is to examine if treatment with liothyronine increases left ventricular ejection fraction (LVEF) in patients with stable, chronic heart failure.

Detailed Description
The patients are examined 3 times. At baseline, after 3 months and after 6 months.After the examination is performed, they begin the study medication while admitted at Dept. of Cardiology, Herlev Hospital, for cardiac monitoring.

Outcome Measures
Primary Outcome Measures
- left ventricle ejection fraction [3 months]

The effect of 3 months low dose liothyronine treatment on body composition in patients with heart failure.
- Quality of Life, questionaire [3 months]
The effect of 3 months low dose liothyronine treatment on quality of life, assessed by SF-36 and Minnesota Living with Heart Failure questionnaires in patients with heart failure.
- YKL-40, YNF-alpha, hsCRP and IL-6 [3 months]
The effect of 3 months low dose liothyronine treatment on low grade inflammation assessed by measurement of pro-inflammatory markers in patients with heart failure.
