non-ST Elevation Myocardial Infarction (NSTEMI): unstable angina
A non-ST elevation myocardial infarction (NSTEMI) is a type of heart attack where the blood flow to the heart is partially blocked. It is considered a medical emergency and requires prompt treatment to prevent further heart damage. Treatment may include medications, such as antiplatelet drugs and anticoagulants, or procedures like angioplasty to restore blood flow to the heart.
