STEMI stands for "ST segment Elevation Myocardial Infarction," more commonly known as a heart attack which is caused by a completely blocked blood vessel. The American Heart Association has established a set of protocols to fast-track emergency cardiac care at STEMI-receiving hospitals such as West Houston Medical Center.

West Houston Medical Center also provides a hypothermia protocol for patients who have suffered cardiac arrest. By cooling body temperature to 91 degrees, brain metabolism decreases, allowing for increased oxygen to the heart. Houston is the first major metropolitan city to be involved in this type of protocol.
