Don’t Lose Heart

Updated: Apr 21, 2023

Your circulatory system is responsible for transporting blood throughout your body. It is made up of your heart and blood vessels.

Your heart pumps blood through the lungs to pick up oxygen and drop off carbon dioxide, and then pumps it through the rest of your body to tiny capillaries that deliver oxygen and nutrients to cells and remove carbon dioxide and cellular waste.

Isn't the human body of brilliant design?

When you experience symptoms in the Circulatory System

Your life is dependent on a healthy functioning heart. It can be scary when things go awry, or you experience chest pains, palpitations or arrhythmia.

Blood clotting and low blood oxygen are other issues that are concerning. These are the topics we’ll be covering this month, to help put your mind (and heart) at ease.

The Mast Cell Connection

If you have been following us for a while, it should come as no surprise that mast cells are involved in heart disease (1). Ischemic heart disease is correlated to high serum histamine (2).

Histamine impacts arteries by stimulating smooth muscle contractions and excitation of nerves (3).

A study looking at how stress triggers mast cell activation in cardiac events reveals how mast cell mediators negatively influence heart and cardiovascular tissue by leading to inflammation (4).

What does all that research tell us? Histamine is a topic worth exploring if you have heart troubles!

The Histamine Connection

Did you know that itching (another histamine-mediated symptoms) is correlated to chronic heart failure (5)? If you are struggling with chronic itch (pruritis) or other histamine mediated symptoms along with your heart concerns, then it is worth considering that they may have the same underlying trigger. Many symptoms, one trigger.

For more on the topic of itch, check out our blog post titled "Itchiness Sure Can Get Under Your Skin".

Sometimes chest pain can result from heartburn or GERD – another possible sign of histamine trouble. If this sounds like you, you may want to check out our blog post on this topic.

Get things checked

Have you ever had unexplained chest pain? Chest pain is not something you should ever ignore. Pain, pressure or tightness in the chest can mean you’re having a myocardial infarction (heart attack) or lung problems, so always have this checked out by a doctor first and foremost.
