Silent Heart Attack Symptoms

Diabetes is particularly important because nerve damage associated with diabetes may reduce a person's ability to perceive certain symptoms. People with diabetes should therefore discuss their cardiovascular risk and preventive care with their healthcare provider.

Why Is a Silent Heart Attack Dangerous?

The main concern is that a person may not realize that heart damage is occurring and therefore may not seek treatment promptly.

A heart attack can damage heart muscle and increase the risk of future cardiovascular problems. Having a silent heart attack can also increase the risk of another heart attack and other complications, including heart failure.

Early treatment matters because restoring blood flow and managing the underlying cause can help limit heart damage.

How Is a Silent Heart Attack Diagnosed?

A silent heart attack may only be identified after the event, particularly when a person undergoes testing for another reason.

A doctor may consider:

Electrocardiogram (ECG)

An ECG records the electrical activity of the heart. Certain changes can provide evidence of a previous or current heart attack.

Echocardiogram

An echocardiogram uses ultrasound to assess the structure and function of the heart. It can identify areas of abnormal heart movement that may be related to previous heart damage.
