The Connection between Syncope and Heart Health


Serious ManSyncope, or unexplained fainting, is a condition that may seem frightening but is relatively harmless by itself. However, the deeper causes of syncope can include serious cardiovascular complications that should be addressed by a qualified health professional.

Causes of Syncope

One of the primary causes of syncope is insufficient blood flow to the brain. This can be caused by hypotension, or low blood pressure. Since every function of our bodies relies on a constant supply of blood that is pumped via the heart, low blood pressure can limit the flow of blood to critical areas of our body, including the head.

Even if blood pressure is normal, if blood flow is blocked within the arteries, the brain may not receive the oxygen it needs. This is a condition called atherosclerosis, or hardening of the arterial walls from plaque buildup. This can lead to many different cardiovascular problems, including experiencing syncope.

The Brain/Body Connection

Syncope and heart disease may seem unrelated at first glance, but when you consider that the heart is responsible for blood delivery throughout the entire body, the connection becomes clearer. Cardiovascular conditions such as hypertension, cardiac arrhythmia and congestive heart failure can all be culprits behind bouts of syncope.

This is actually a positive aspect of syncope, as far as cardiovascular diseases go. While infrequent fainting spells may not be harmful themselves, they are often an indicator of underlying problems that may be more serious.

Syncope can be used to alert you to possible serious cardiac issues that may be preventing proper blood flow to your brain. If you experience syncope, you should consult with your doctor as soon as possible for further testing to understand what might be causing the condition.
