The Claim
In conscious baboons, four weeks of thyroid hormone administration significantly increases resting left ventricular contractility (dP/dtmax from 2318±829 to 3073±1034 mm Hg/s) and accelerates ventricular relaxation (tau from 28.2±5.4 to 24.0±5.5 ms), indicating enhanced cardiac performance at rest without changes in heart rate.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Giving thyroid hormone to baboons for four weeks makes their hearts pump more strongly and relax faster while at rest, without changing their heart rate — like giving the heart a boost in efficiency.

What the research says
1 studyStudy: Effects of thyroid hormone on cardiac beta-adrenergic responsiveness in conscious baboons.
The study gave baboons thyroid hormone for four weeks and found their hearts pumped stronger and relaxed faster at rest—just like the claim says. No magic, just science.
