8 Subtle Warning Signs Of Silent Heart Attacks That Are Often Missedimage © BruceBlaus – Wikipedia – lic. under CC-BY-3.0

Coronary artery disease is the leading killer of men and women in Western civilization. In the US, more than half a million people die from heart disease each year and approximately three million have silent heart attacks, experiencing minimal symptoms and having no idea there is anything wrong until they are in mortal danger. [1]

The thing that makes the symptoms in this list subtle is you need to undergo laboratory “blood work” tests to identify them – which is why regular health checkups are needed in order to identify a possible development of heart disease at its early stage. It’s also vital to start eating healthy, be physically active and learn stress management techniques to keep your heart well.

The following are eight subtle signs of heart disease:

1. Insulin Levels: Several studies have shown that higher insulin levels are associated with an increased risk of cardiovascular disease. [2]

2. Triglyceride to HDL Ratio: This is the ratio between the levels of triglyceride to HDL (good cholesterol) in your blood. Triglyceride is a type of fat found in the blood and too much of this can lead to coronary artery disease. [3]

3. High-sensitivity C-reactive Protein: C-reactive proteins are produced in the liver in response to bodily inflammation. An unusual amount of this protein can indicate vascular infection. [4]

4. Red Blood Cell Magnesium Levels: Magnesium deficiency can cause seizures and spasms in the arteries which can result in heart attacks. [5]

5. Homocysteine Levels: Homocysteine is an amino acid found in the blood which is acquired mostly from eating meat. Elevated levels of this amino acid have shown to be strongly linked to cardiovascular disease. [6]

6. Ferritin Levels: Ferritin is a type of protein which contains iron. Iron is essential for many physiological processes but high levels of ferritin have been known as a risk factor in the progression of coronary artery disease. [7]

7. Signs of Chronic Infections: A large number of studies have reported on associations of coronary heart disease and certain persistent bacterial and viral infections. [8]

8. Testosterone Levels: A recent study has shown that male testosterone levels play a central role in worsening lipoprotein patterns and causing greater susceptibility to heart disease. [9]
