Heart Attacks and Inflammation: Before and After

Our heart is “simply” a large muscle that continuously pumps oxygen-rich blood throughout the body supplying cells, tissues and organs with life-giving oxygen and nutrients. The cells of the body release carbon dioxide and other gases as a by-product of producing energy. These gases are removed from the blood as it circulates through the lungs.

A heart attack results when blood is blocked from getting into the arteries that feed the heart. If not treated rapidly, parts of the heart muscle may die from lack of oxygen. After a heart attack, danger signals released by dying cells trigger inflammation which in turn attracts immune cells into the area to clear dead cells and tissue debris.

The high numbers of inflammatory immune cells stick to the plaque, increasing the risk for another heart attack. The body tries to heal itself by transforming the damaged heart muscle cells into scar tissue. Because scar tissue is hard and not flexible, a badly scarred heart cannot pump blood efficiently.

For any sort of healing, the body has to produce the right amount of inflammation. There has to be sufficient inflammation for the healing process, but not so much that excessive scarring occurs. Depending on how much scar tissue forms, congestive heart failure may result due to the inability of the heart to pump normally.

Our cells produce cholesterol which is essential for a wide range of biological functions. The body has to manufacture the right amount of cholesterol and which has to go to specific parts of the body. If too much cholesterol is produced over many years, cholesterol plaque builds up in the arteries resulting in atherosclerosis. Atherosclerosis is triggered by lifestyle issues that cause uncontrolled inflammation such as high blood pressure, smoking, poor dietary choices and excessive weight.

Plaque deposits narrow the passageways of arteries and block the flow of blood in vessels that feed the heart itself. The plaque may eventually harden, burst and release blood platelets that form clots in an attempt to stop the bleeding. The blood clots may cause even more blockages in the arteries, obstructing blood and oxygen flow and causing more heart damage. An artery to the heart which is blocked may result in a heart attack; a blocked artery in or leading to the brain results in a stroke.

What is a Heart Attack?

In Summary:

1) Acting fast at the first sign of heart attack symptoms can save lives and limit damage to the heart. Heart attack treatment works best when it’s given right after symptoms occur. If you think you, or someone else is having a heart attack, even if you’re not sure, call emergency services immediately.

2) Current therapies for atherosclerosis and cardiovascular disease do not target inflammatory cells. Maintaining the body in immune homeostasis, immune balance, may help the body support healthy heart and cardiovascular function.

Inflammation and Coffee: Its Ability to Down Regulate Inflammatory Responses

When I ask people for their typical dietary intake, many people “shamefully” tell me that they drink coffee. It surprises them when I ask “what is wrong with that”? Coffee is a healthy addition to one’s diet because it can help the body regulate its immune inflammatory responses.

Studies have shown that coffee consumption reduces the risk of conditions such as diabetes, neurological diseases, cardiovascular disease, certain cancers, depression,and back and neck pain to mention a few.

Diabetes
Phytonutrients, plant compounds, other than caffeine, found in coffee, are reported to reduce blood sugar levels, and decrease the way the body stores carbohydrates and fats. Data from over 450,000 people found that every additional cup per day of caffeinated or decaffeinated coffee lowers the risk of diabetes by 5 to 10%. Heavy consumers of coffee, 12 cups/day, have a 67% lower risk of getting diabetes. The effect is not due to the caffeine found in coffee, but to other compounds in coffee.

Parkinson’s Disease
In Parkinson’s disease, caffeinated coffee may protect nerve cells from destruction, decrease the incidence of Parkinson’s, and the improve mobility of individuals with Parkinson’s disease. In the case of Parkinson’s, the caffeine in coffee is the “magic ingredient”, since decaffeinated coffee does not have the same affect. Women with Parkinson’s Disease, that were on hormonal replacement therapy, showed less benefit from coffee.

Alzheimer’s and Dementia
As mentioned above, caffeine may help the body protect nerve cells. Consuming caffeinated coffee over a long period appears to decrease the risk of dementia or Alzheimer’s.

Heart Disease
In other studies, although coffee may raise blood pressure for a brief time, after two months of daily coffee consumption, blood pressure is reduced. It also lowers the risk of heart disease and reduces stroke incidents.

Cancer
Drinking one cup of coffee a day has been associated with a 42% lower risk of liver cancer. Women that drank two or more cups of coffee per day had a delayed onset of a hard-to-treat cancer. Individuals drinking three cups of coffee a day had a 40% lower risk of developing pharyngeal, esophageal, and oral cancers. Men who drank over six cups of caffeinated or non-caffeinated coffee a da,y had an 18% lower risk of prostate cancer, and a 40% lower risk of aggressive prostate cancer. Individuals that were heavy coffee drinkers had a 30% lower risk of colorectal cancer.

Depression
A study of over 50,000 women, found that 4 cups of coffee daily lowered their risk of depression by 20%.

Coffee and Pain Responses
Subjects who consume coffee while working at the computer, report less pain in their back and necks than those that abstain from drinking coffee

Inflammatory Responses and Coffee:
Regular coffee consumption affects the production of cytokines, such as IL-1 and IL-10 that regulate immune inflammatory responses. The data suggests that the benefits of coffee consumption are due to the phytonutrients, plant nutrients, and caffeine found in coffee. The adage that “coffee is not good for you”, should be re-examined.
