Heart Attack Symptoms Aren’t Always Loud, They Can Be Silent Too

What is a Silent Heart Attack?

Did you know you may be suffering from a heart attack and not even know it? This is known as a silent heart attack. Like any other heart attack, a silent heart attack blocks the blood flow to your heart, resulting in possible muscle damage. The reason this type of heart attack is considered “silent” is because of its non-diagnosable symptoms.

The symptoms of a silent heart attack are not that intense as compared to a normal heart attack. You likely will not be able to recognize them as a symptom of a heart attack, even if you feel any.

These types of heart attacks affect everyone differently. It represents 45% of all heart attacks and is considered a "silent killer."

What Are the Causes of a Silent Heart Attack?

The causes are very similar to a normal heart attack. The heart muscles are damaged because of the absence of oxygen due to a blocked artery in the heart. Risk factors are similar to a normal heart attack as well, such as:

  • High cholesterol
  • Smoking
  • Diabetes
  • High blood pressure
  • Family history of heart attack
  • Age risk in men and women
  • Stress
  • Lack of physical activity
  • Obesity

What Are the Signs and Symptoms?

Although the symptoms are not as severe as a typical heart attack, they are often misunderstood or misdiagnosed for other conditions. These are:

  • Slight pain. Slight pain or discomfort is felt but not in the chest like a regular heart attack. You may feel an insignificant pain in the upper abdomen or your jaw. Sometimes, it even appears as a strained muscle.
  • Burning sensation. You may feel heartburn or indigestion, but as a mild pain in the throat.
  • Breathing issues. If you are experiencing issues with your breathing, it could be a sign of a silent heart attack.

They are usually diagnosed during routine checkups. It is generally diagnosed by having a CT scan or MRI of your heart. If the test results show damaged muscles, then it indicates a silent heart attack. Another important diagnostic test is blood tests carried out in emergency departments of patients with a high risk of a heart attack.
