How to Pronounce ST-Elevation Myocardial Infarction

Say it like this: ES-TEE eh-leh-VAY-shun my-oh-KAR-dee-al in-FARK-shun. The stress falls on the second syllable of "elevation" (VAY), the second syllable of "myocardial" (KAR), and the second syllable of "infarction" (FARK). Take your time with each part, and you'll have it down.

STEMI is short for ST-Elevation Myocardial Infarction. You say it like "STEM-ee" (rhymes with "ready"). Doctors and nurses use this shorter term all the time in hospitals because it's much faster to say than the full name.

Myocardial comes from two Greek roots: "myo" means muscle, and "cardial" relates to the heart. So "myocardial" literally means "of the heart muscle." Understanding these roots helps you remember that this term is specifically about the heart itself.

Infarction comes from a Latin word meaning "to stuff in" or "to block." In medical language, it describes an area of tissue that has been damaged or died because its blood supply was blocked off. Think of it as tissue that lost its oxygen supply.

Break it like this: ST / eh-leh-VAY-shun / my-oh-KAR-dee-al / in-FARK-shun. The tricky parts are "myocardial" (four syllables) and "infarction" (three syllables), so practice those separately if needed.

Many people stress the wrong syllables—they might say "my-oh-CAR-dee-al" instead of "my-oh-KAR-dee-al," or "in-far-SHUN" instead of "in-FARK-shun." Remember: the stress in myocardial falls on KAR, and in infarction it falls on FARK (with a hard K sound).

Here's an example: "The emergency room doctor explained that the patient had an ST-Elevation Myocardial Infarction." Or more simply: "The patient was diagnosed with STEMI."

You might hear "myocarditis" (my-oh-kar-DY-tis)—inflammation of the heart muscle—or "myocardial ischemia" (my-oh-KAR-dee-al is-KEY-mee-uh)—reduced blood flow to heart muscle. Both share the "myo" and "cardial" roots related to the heart muscle.
