Myocardial infarction (MI) is the death of myocardial tissue usually caused by a blocked coronary artery. Acute MI (AMI) is classified to ICD-9-CM category 410, with a fourth and fifth digit needed to completely code the condition. The fourth digit specifies the site involved.
Symptoms. Up to 25% of patients have no symptoms of an MI. If symptoms do occur, they may include substernal chest pain; left arm, neck, or jaw pain; shortness of breath; indigestion; and nausea or vomiting. Atypical or less prominent symptoms are usually found in diabetic, female, or older adult patients.

An acute myocardial infarction (AMI), also known as a myocardial infarction (MI), is also referred to as a heart attack. An acute myocardial infarction occurs when the flow of oxygen-rich blood to an area of the heart muscle suddenly becomes blocked (occluded), preventing enough oxygen from getting to the heart.
Signs and Symptoms. Heart attacks do not always have symptoms, which is why it is referred to as a silent heart attack. When an AMI does present with symptoms, the symptoms can vary from person to another and from one heart attack to the other in the same person. Diabetics may have no symptoms or very mild ones.
Other names for myocardial infarction and heart attack are: The term myocardial relates to the heart’s muscular tissue. “Myo” means muscle, and “cardial” means heart. In farction means death of tissue (necrosis) caused by lack of blood supply. The Centers for Disease Control and Prevention (CDC) reports that heart disease is the leading cause ...
In order to make a diagnosis, the physician will perform the following: Electrocardiogram (ECG or EKG). This 12-lead ECG is often done by paramedics on site or enroute to the hospital.
A STEMI, the most serious type of MI, is also called a Q-wave or transmural myocardial infarction. A Non-ST elevation myocardial infarction (NSTEMI) is caused by a partial or temporary blockage. The extent of the damage to the heart muscle may be relatively small based on the blood supplied by the affected artery.
When an AMI does present with symptoms, the symptoms can vary from person to another and from one heart attack to the other in the same person. Diabetics may have no symptoms or very mild ones.
