Cardiovascular Disease Overview (Holistic)

About This Condition

A heart-to-heart on cardiovascular disease: Make simple changes to help you beat the odds against heart disease, a leading cause of death.
  • Get smoke-free

    Quit smoking and stay clear of cigarette smoke to lower your risk of several types of cardiovascular disease

  • Watch what you eat

    Eat lots of fruits, vegetables, legumes, whole grains, fish, and avoid fats from meat, dairy, and processed foods high in hydrogenated oils

  • Stay active

    Couch potatoes have increased cardiovascular disease risk, so make sure you get regular exercise

  • Get tested

    See your doctor to find out if you have problems with high blood pressure or high blood levels of cholesterol, triglycerides, or glucose

About

About This Condition

Cardiovascular disease is a wide-encompassing category that includes all conditions that affect the heart and the blood vessels.

Cardiovascular disease is the number one cause of death in the United States. This introductory article briefly discusses several diseases that have a role in the development of cardiovascular disease. Many risk factors are associated with cardiovascular disease; most can be managed, but some cannot. The aging process and hereditary predisposition are risk factors that cannot be altered. Until age 50, men are at greater risk than women of developing heart disease, though once a woman enters menopause , her risk triples.1

Many people with cardiovascular disease have elevated or high cholesterol levels.2 Low HDL cholesterol (known as the “good” cholesterol) and high LDL cholesterol (known as the “bad” cholesterol) are more specifically linked to cardiovascular disease than is total cholesterol.3 A blood test, administered by most healthcare professionals, is used to determine cholesterol levels.

Atherosclerosis (hardening of the arteries) of the vessels that supply the heart with blood is the most common cause of heart attacks . Atherosclerosis and high cholesterol usually occur together, though cholesterol levels can change quickly and atherosclerosis generally takes decades to develop.

The link between high triglyceride levels and heart disease is not as well established as the link between high cholesterol and heart disease. According to some studies, a high triglyceride level is an independent risk factor for heart disease in some people.4

High homocysteine levels have been identified as an independent risk factor for heart disease.5 Homocysteine can be measured by a blood test that must be ordered by a healthcare professional.

Hypertension (high blood pressure) is a major risk factor for cardiovascular disease, and the risk increases as blood pressure rises.6 Glucose intolerance and diabetes constitute separate risk factors for heart disease. Smoking increases the risk of heart disease caused by hypertension.

Abdominal fat, or a “beer belly,” versus fat that accumulates on the hips, is associated with increased risk of cardiovascular disease and heart attack.7 Overweight individuals are more likely to have additional risk factors related to heart disease, specifically hypertension, high blood sugar levels, high cholesterol, high triglycerides, and diabetes.

Symptoms

People with cardiovascular disease may not have any symptoms, or they may experience difficulty in breathing during exertion or when lying down, fatigue, lightheadedness, dizziness, fainting, depression , memory problems, confusion, frequent waking during sleep, chest pain, an awareness of the heartbeat, sensations of fluttering or pounding in the chest, swelling around the ankles, or a large abdomen.

Healthy Lifestyle Tips

Both smoking8 and exposure to secondhand smoke9 increase cardiovascular disease risk.

Moderate exercise protects both lean and obese individuals from cardiovascular disease.10

Eating Right

The right diet is the key to managing many diseases and to improving general quality of life. For this condition, scientific research has found benefit in the following healthy eating tips.

Recommendation Why
Eat healthfully
Eat lots of fruits, vegetables, legumes, whole grains, fish, and avoid fats from meat, dairy, and processed foods high in hydrogenated oils

A high intake of carotenoids from dietary sources has been shown to be protective against heart disease in several population-based studies.11 , 12 A diet high in fruits and vegetables,13 fiber ,14 and possibly fish15 appears protective against heart disease, while a high intake of saturated fat (found in meat and dairy fat) and trans fatty acids (in margarine and processed foods containing hydrogenated vegetable oils)16 may contribute to heart disease. In a preliminary study, the total number of deaths from cardiovascular disease was significantly lower among men with high fruit consumption17 than among those with low fruit consumption. A large study of male healthcare professionals found that those men eating mostly a “prudent” diet (high in fruits, vegetables, legumes, whole grains, fish, and poultry) had a 30% lower risk of heart attacks compared with men who ate the fewest foods in the “prudent” category.18 By contrast, men who ate the highest percentage of their foods from the “typical American diet” category (high in red meat, processed meat, refined grains, sweets, and desserts) had a 64% increased risk of heart attack, compared with men who ate the fewest foods in that category. The various risks in this study were derived after controlling for all other beneficial or harmful influencing factors.

A parallel study of female healthcare professionals showed a 15% reduction in cardiovascular risk for those women eating a diet high in fruits and vegetables—compared with those eating a diet low in fruits and vegetables.19

Limit salt
High salt intake has been tied to increased cardiovascular disease incidence and death among overweight, but not normal weight, people. Further research is needed to confirm the link.

Preliminary evidence has linked high salt consumption with increased cardiovascular disease incidence and death among overweight, but not normal weight, people. Among overweight people, an increase in salt consumption of 2.3 grams per day was associated with a 32% increase in stroke incidence, an 89% increase in stroke mortality, a 44% increase in heart disease mortality, a 61% increase in cardiovascular disease mortality, and a 39% increase in death from all causes.20

Enjoy alcohol now and then
Drinking alcohol moderately appears to protect against heart disease.

Moderate alcohol consumption appears protective against heart disease.21 However, regular, light alcohol consumption in men with established coronary heart disease is not associated with either benefit or deleterious effect.22

Supplements

What Are Star Ratings?

Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.

2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.

1 Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Supplement Why
2 Stars
Sea Buckthorn
10 mg three times daily of a flavonoid extract of sea buckthorn for six weeks
Sea buckthorn berries, their oil, or flavonoid-rich extracts of the fruit have lowered biochemical indicators of increased cardiovascular risk in some, though not all, preliminary and double-blind human studies.
Sea buckthorn berries, their oil, or flavonoid-rich extracts of the fruit have lowered biochemical indicators of increased cardiovascular risk in some,23 , 24 , 25 though not all,26 , 27preliminary and double-blind human studies. In a preliminary trial, people with heart disease who took 10 mg three times daily of a flavonoid extract of sea buckthorn for six weeks had less chest pain, lower blood cholesterol, and improved heart function.28 Double-blind research is needed to confirm these findings.
