The sudden death of IU Police Chief Keith Cash was caused by a heart problem, aortic stenosis.

Aortic Stenosis occurs when a valve in the heart starts to narrow and becomes smaller.  This causes another part of the heart to work overtime.

“So the left ventricle has to work so much harder to pump the blood through that narrowed opening and the consequence of that is the left ventricle begins to enlarge is size and becomes quite thickened,” said Dr. Yousuf Mahomed with IU Health.

That eventually leads to heart failure.

Most people generally develop symptoms over time. Symptoms include shortness of breath, chest pains, and light headedness.

Sadly for some, the first symptom of the problem is a deadly heart attack.
