This was tested in people. That is the most reliable kind of research we share.
This watched people already in care. It is not a treatment being tested.
The short version
People with pituitary tumors had more early heart stiffness than healthy people did.
What was studied. Doctors studied 214 people seen between 2016 and 2018. The group had 91 with prolactinoma, 26 with acromegaly, 45 with a pituitary tumor that makes no hormones, and 52 healthy people.
What they found. The team used heart scans to look for a problem where the heart does not relax well. It showed up in 21.5% of everyone studied. By group, it was found in 5.8% of healthy people, 19.8% of the prolactinoma group, 46.2% of the acromegaly group, and 28.9% of the no-hormone tumor group. Most cases, 84.8%, were the mildest grade.
What this means, and what it doesn't
What it could mean: If you have a pituitary tumor, your heart may be worth checking. This looks most true for people with acromegaly. Blood sugar and heart scans may be part of that check. Ask your doctor what makes sense for you.
What it doesn't mean: This does not mean a pituitary tumor will cause heart failure. The study looked at people at one point in time. So it cannot prove the tumor caused the heart changes. It was done at one center, and the authors say bigger studies are needed. It is not a new treatment and not a cure.
