Angina Pectoris

What Is Angina Pectoris?

[dropcap]A[/dropcap]ngina pectoris, or simply angina, is a coronary syndrome characterized by an oppressive substernal pain (pain under breastbone) or pressure brought on by exertion and relieved by rest that results from failure of coronary arteries to deliver adequate oxygen to heart tissue due to ischemic heart disease.

Q: Why do coronary arteries fail to deliver adequate oxygen to heart tissue?

A: Coronary arteries are the blood vessels that serve the heart. In angina, these vessels fail to deliver adequate oxygen to heart tissue because they are narrowed or blocked by fatty buildups, called atherosclerotic plaques or by a blood clot which impair their ability to carry adequate blood that carries the oxygen. Diseased coronary arteries cannot deliver adequate oxygenated blood pumped by the heart to its own muscle cells.

The heart is a muscular organ that is working all the time without rest, so it needs a constant supply of oxygen. When heart muscle has to work harder, it needs more oxygen. Lack of oxygen causes pain which makes the affected person stop activity and rest.

Angina can be stable or unstable. Unstable angina is much more serious and can be life-threatening.

• Stable angina produces predictable pain and responds to rest and/or medication. It is less serious than unstable angina but can be very painful or uncomfortable. Anything that makes the heart muscle need more oxygen can cause an angina attack in someone with heart disease, including: smoking, cold weather, exercise, emotional stress, obesity, and large meals. Other causes of angina include: abnormal heart rhythms (usually ones that cause the heart to beat quickly), anemia, coronary artery spasm, heart failure, heart valve disease, and hyperthyroidism (overactive thyroid).¹
• Unstable angina produces unpredictable pain that may occur at rest, lasting more than 20 minutes. It is more severe than stable angina and less responsive to medication. Atherosclerosis is by far the most common cause of unstable angina. Oxidized low-density lipoprotein, so-called bad cholesterol, and oxysterols play an important role in atherogenesis, the development of atherosclerosis. Coronary arteries that are narrowed by atherosclerotic plaques can rupture causing injury to the coronary blood vessel resulting in blood clotting which blocks the flow of blood to the heart muscle. Blood clots may form, partially dissolve, and later form again and angina can occur each time a clot blocks blood flow in an artery. People with unstable angina are at increased risk of having a heart attack.²

What Is Angina In Celiac Disease and/or Gluten Sensitivity?

• Relationship between angina pectoris and celiac disease. Angina pectoris is a serious cardiovascular disorder associated with celiac disease.
• Relationship between angina pectoris and death in celiac disease. Cardiovascular disease is the most common cause of death in patients with celiac disease. Chronic inflammation in the general population is a major risk factor for ischemic heart disease. Many patients with celiac disease have been exposed to long-term inflammation in the bowel both before and after diagnosis of celiac disease.
• Relationship between angina pectoris and diet. Roughly 17% of the patients with celiac disease have low dietary adherence. Low dietary adherence is associated with persistent inflammation and therefore might explain the increased risk of ischemic heart disease observed in patients with celiac disease.³

How Prevalent Is Angina In Celiac Disease and/or Gluten Sensitivity?

The largest study to date on ischemic heart disease (IHD) risk in celiac disease, with almost 1000 deaths from IHD during follow-up, examined the risk of IHD incidence in individuals with celiac disease based on small intestinal histopathology (biopsy). Reseachers found that individuals with celiac disease or small intestinal inflammation have a 19% increased risk of IHD. A positive association between latent celiac disease (non-inflammatory) and IHD was not found.³

What Are The Symptoms Of Angina?

Angina pectoris is marked by these symptoms:

• Pain or pressure in the chest which may radiate down the arm or into the jaw, shoulders or neck, lasting more than 20 minutes. Unstable angina frequently develops in the morning.
• May be accompanied by shortness of breath, nausea or vomiting, sweating, anxiety or fear.
• Pulmonary edema develops in unstable angina without treatment.

How Does Angina In Celiac Disease and/or Gluten Sensitivity Develop?

• Unstable angina pectoris results from inadequate blood flow and oxygenation to heart tissue due to atherosclerosis. However, atherosclerosis develops in arteries that are hardened by sustained high homocysteine levels in the bloodstream.  Elevated homocysteine, a transient amino acid, directly results from nutritional deficiencies of vitamin B12, folate, pyridoxine (vitamin B6), and EPA omega-3 fatty acid.

• Chronic selenium and vitamin E deficiencies are associated with inflammation and increased risk for cardiovascular disease. All these deficiencies are common in celiac disease.

• Stable angina results from inadequate oxygenation to the heart in these conditions:

• Anemia which limits the ability of blood to carry oxygen.
• Anxiety which constricts vessels thereby limiting their ability to transport oxygenated blood.
• Stress which increases the demand for oxygen.

Does Angina Respond To Gluten-Free Diet?

Overall diet content is very important. Large meals and rich foods should be avoided.

A meta-analysis (examination) of 9 cohort studies observed a protective effect of fruits and vegetables by means of their protective constituents such as potassium, folate, vitamins, fiber, and other phenolic compounds in the risk of developing coronary heart disease and stroke. The study consisted of 91,379 men, 129,701 women, and 5,007 coronary heart disease (CHD) events. The risk of CHD was decreased by 4% for each additional portion per day of fruit and vegetable intake and by 7%  for fruit intake.⁴

6 Steps To Improve Angina  Related to Celiac Disease and/or Gluten Sensitivity:

• [dropcap]1[/dropcap]Remove the Trigger. Maintain a Strict, Nutritious Gluten Free Diet:

[box type=”shadow” ]Treatment. This condition responds to the complete elimination of gluten, which is the required treatment that improves both angina and gut health.

• Gut health is the foundation to restore ALL health. Restored health will enable you to maintain a strict gluten free diet, just as other life tasks will be easier.
• A strict gluten free diet means removing 100% of wheat, barley, rye and oats from the diet.
• Cutting out bread and other obvious sources of gluten is not good enough for recovery. Even 1/8th teaspoon of flour or bread crumb is enough to sustain the inflammation that is damaging your small intestine, causing increased permeability (leaky gut) and allowing undigested gluten to enter your body where it can damage structures and function, and instigate immune inflammatory responses.

Correct Your Individual Nutritional Needs.

• Eat foods that can replenish missing nutrients. Find them under NUTRIENT DEFICIENCIES.
• Take nutritional supplements as needed. Find them under NUTRIENT DEFICIENCIES.

Recovery. You should begin to feel better within a week and notice more energy as inflammation subsides and the  absorbing cells that make up the surface lining of your small intestine are better able to function.

• Intestinal lining cells are replaced every 5 days. The healing process is like sunburn where the damaged surface layer of skin sloughs off and is replaced with new normal cells.
• Leaky gut normally resolves in two month after starting a gluten free diet and brings about a big improvement in health. Improvement in intestinal permeability precedes morphometric recovery (cell appearance and structure) of the small intestine in celiac disease.⁵
• The intestinal lining may take up to a year to heal.[/box]

• [dropcap]2[/dropcap] Reduce Inflammation. Foods to Eat and Foods Not to Eat:

Because gluten is inflammatory, eliminate OTHER inflammatory foods from your diet to reduce an additive effect to gluten. At the same time, try to eat foods that reduce inflammation (anti-inflammatory).

[box type=”shadow” ]Here Are Major Inflammatory Food Types That Reduce Healing:

• Damaging Foods. In susceptible persons, includes corn, dairy (cow), and soy. Lactose, the sugar in any animal milk disrupts intestinal permeability causing leaky gut.⁶
• Allergenic Foods. Includes foods that trigger the immune sytem to produce IgE antibodies. Allergy testing is the usual way to discover these offending foods.
• Shelf Stable Processed Foods. Includes any that contain additives and preservatives. Look for them on the nutrition label of the box or package. Additives and preservatives also disrupt intestinal permeability causing leaky gut.⁶
• Fats. Limit deep fried foods, trans-fats, saturated fats (animal fat/butter), and EXCESSIVE omega-6 fatty acid oils like corn oil. Rancid fats, sodium caprate (a medium chain fat), and sucrose monester fatty acid (a food grade surfactant) induce significant disruption of the intestinal barrier that causes leaky gut.⁶.
• Excessive Refined White Flours (bran layer removed). Includes products made from them such as cookies, bread, cakes, pies. Bran contains the vitamins and minerals that metabolize grains and slows the otherwise rapid entry of sugar from their digestion into the bloodstream. Also disrupt intestinal permeability causing leaky gut.⁶
• Refined Sugars.  Includes white sugar, corn fructose and high fructose corn syrup.
• Certain Spices. Includes paprika and cayenne pepper which disrupt intestinal permeability causing leaky gut.⁶
• Alcohol and Caffeine. Disrupt intestinal permeability causing leaky gut.⁶[/box]

[box type=”shadow” ]Here Are Important Anti-Inflammatory Food Types to Promote Health:

• Fruits. Contain ample amounts of vitamins, minerals and phytochemicals which are naturally occuring components in plants that detoxify toxins, carcinogens (reducing the risk by 50%) and mutagens.
• Non-Starchy Vegetables. Support intestinal integrity and provide ample amounts of vitamins, minerals and phytochemicals. Includes lettuce, kale, onion, broccoli, garlic, and others.
• High Quality Complex Carbohydrates. Provide vitamins, minerals, and fiber while boosting serotonin levels to help you relax and feel calm. Includes whole grains, legumes, and root vegetables such as carrots, parsnips, sweet potatoes, turnips, red beets, and others.
• Antioxidants. Protect the body from inflammatory oxidant molecules that continually occur and help us handle stress and reduce irritability. Includes vitamin C-containing foods such as lemon, grapefruit, apricot, Brussels sprouts and strawberries, and others. Also, includes vitamin E-containing foods such as nuts, seeds, avocado, olive oil, and others. Cocoa is good, too.
• Omega-3 Fatty Acids. Balance opposing omega-6 fatty acids and bad fats. Fish sources includes tuna, salmon, cod, and others. Plants sources include flax, chia seeds, canola oil, and others.
• Probiotics. Supply normal microbes needed for colon health and health of the body such as these fermented foods: yogurt, kefir, and unpasteurized apple cider vinegar.
• Prebiotics/ High Fiber Foods.  Food with fiber keeps our population of colonic microbes healthy.
• Protective Herbs and Spices.  See below #6 below for examples.[/box]

• [dropcap]5[/dropcap]Nutritional Supplements To Help Correct Deficiencies:

[box type=”shadow” ]

• Multivitamin/mineral combination once a day is useful to improve overall nutrient levels. This is a safe dose, but always check with your doctor to avoid interactions with medications.
• 100% of the B vitamins, or as prescribed by a doctor. About B Vitamin Complex supplements:  some labeling can be confusing, for example, “B 100” does not mean 100%. If the ingredient list shows  an excessive amount like 3000% or more, look for another brand because this excessive amount will cause the loss of mineral in the urine.
• Selenium as prescribed  to restore normal blood level.
• EPA in fish oil preparations.

Storage Note: Store container tightly sealed, away from heat, moisture and direct light to avoid loss of potency. That is, in a safe kitchen cabinet – not in the bathroom or on the kitchen table. Fish oil goes in the refrigerator[/box]

• [dropcap]6[/dropcap]Manage Natural Remedies: 

[box type=”shadow” ]Hydration:

• Eight glasses of water are recommended per day unless there is a contraindication such as kidney or heart disease. The Institute of Medicine recommends approximately 2.7 liters (91 ounces) of total water, from all beverages and foods, each day for women and 3.7 liters (125 ounces) daily of total water for men.
• If you are thirsty, drink water. Add fresh, squeezed lemon to water. Lemon is anti-inflammatory, alkalizing and provides vitamin C.
• Hydration Test: Urine should be pale yellow. Fingertips should be plump, without pruning but this may not be reliable when fingers are swollen with edema. Lips should be plump, without puckering. The feeling of thirst can be unreliable.
• What is wrong with soda, coffee, tea, and alcohol? These drinks are dehydrating, increase acid, and deplete nutrients.[/box]

[box type=”shadow” ]Carminatives. The following  anti-inflammatory plant sources called carminitives help heal the digestive tract. They also tone the digestive muscles which improves peristalsis, thus aiding in the expulsion of gas from the stomach and intestine to relieve digestive colic and gastric discomfort.

Carminative Food Remedies:

• Raspberry.
• Carrot is also a cleansing digestive tonic.
• Grape is also bile stimulating and a cleansing remedy for sluggish digestion and laxative.
• Redbeets also stimulate and improve digestion and are easily digested.
• Cabbage also stimulates and improves digestion and is also a liver decongestant.
• Lettuce also stimulates and improves digestion and is also an alterative, meaning it improves the function of organs involved with the digestion and excretion of waste products to bring about a gradual change.
• Potatoes are antispasmodic (due to atropine like properties) and a liver remedy.

Carminative Herb Remedies:

• Sage is also a digestive, astringent, bile stimulant and energy tonic that heals the mucosa.  Drink as tea or use in cooking.
• Chamomile, lemon balm, and fennel, (as a tea) also help relieve nervous tension.
• Parsley also relieves indigestion.
• Rosemary as a tea and in cooking also is a nervous system tonic for stress and fatigue, bile stimulant, and can relieve headaches and indigestion.
• Thyme is also soothing remedy useful for stimulating digestion of rich, fatty foods.

Carminative Spice Remedies:

• Cloves are also antispasmodic.
• Nutmeg is also useful for indigestion.
• Ginger.[/box]

[box type=”shadow” ]Exercise Helps:

Gentle exercise improves circulation and rids the body of toxins. Exercise only up to the point of pain to prevent tissue damage from lack of oxygen.

• Walking is aerobic exercise that reconditions the whole body to improve stamina. Read more about Exercise and Fitness.
• Weight training builds muscle. Read more about Exercise and Fitness.
• Stretching improves flexibilty. Read more about Exercise and Fitness.

Note: Exercise is important, but the amount and type of exercise undertaken depends on your health. Your first priority is to heal. [/box]

What Do Medical Research Studies Tell About Angina In Celiac Disease and/or Gluten Sensitivity?

RESEARCH STUDY SUMMARIES

“Nationwide cohort study of risk of ischemic heart disease in patients with celiac disease.” In this Swedish population-based cohort study, researchers examining the risk of ischemic heart disease incidence in individuals with celiac disease based on small intestinal histopathology found that individuals with celiac disease or small intestinal inflammation are at increased risk of incident ischemic heart disease. A positive association between latent celiac disease and incident ischemic heart disease was not shown.

Ischemic heart disease (IHD) was defined as death or incident disease in myocardial infarction or angina pectoris in Swedish national registers. In 2006 to 2008, duodenal/jejunal biopsy data was collected on celiac disease (equal to villous atrophy; Marsh 3 in 28,190 unique individuals) and inflammation without villous atrophy (Marsh 1 to 2 in12, 598 individuals) from all 28 pathology departments in Sweden. A third cohort consisted of 3658 individuals with normal mucosa but positive celiac disease serology (Marsh 0, latent celiac disease). An increased risk of incident IHD was found in patients undergoing small intestinal biopsy that was independent of small intestinal histopathology (CD:  991 events; inflammation: 809 events; and latent CD: 62 events). Celiac disease and inflammation were both associated with death resulting from IHD, whereas latent CD was not.⁷

“Coronary atherosclerosis and oxidative stress as reflected by autoantibodies against oxidized low-density lipoprotein and oxysterosis.” This study investigating the relevance of oxysterols and autoantibodies against oxLDL (low density lipoprotein or so-called bad cholesterol) to coronary artery disease in 183 patients undergoing coronary angiography demonstrated oxLDL is immunogenic, and autoantibodies against oxLDL are detectable in serum. Antibodies, but not oxysterol concentrations, were significantly greater in subjects with unstable angina that with stable angina. Researchers concluded that anti-oxLDL antibody and oxysterol concentrations are associated with coronary artery stenosis, and oxidative stress may be greatly increased in unstable angina.⁸
