Heart Health – Do you need to supplement L-Carnitine?
This is probably a supplement you’ve never heard of, but when supplemented along with coenzyme Q10 substantial benefits have been seen in individuals with heart disease.
L-carnitine is a compound produced by the liver and kidneys from the biosynthesis of the amino acids lysine and methionine. To form L-carnitine you also need adequate levels of vitamin C, B6, niacin, and iron.
Let me explain how L-carnitine works. The powerhouse of your cells is the mitochondria and produces the energy your heart needs to function. L-carnitine is responsible for transporting fatty acids to the mitochondria for energy production. The heart typically gets 60% of its energy from fat sources. If this process is slowed due to a lack of L-carnitine heart function is affected, especially compounding problems for individuals with heart disease. Those with moderate to severe atherosclerosis (hardening of the arteries due to inflammation and cholesterol deposits) and congestive heart failure are most affected by a deficiency of L-carnitine. Too make matters worse, damaged heart tissue has a hard time “holding on” to L-carnitine resulting in a deficiency.
If you remember back to the information I shared on Coenzyme Q10, Coenzyme Q10 directly affects energy production in the mitochondria. When Coenzyme Q10 levels are low, cells are unable to produce energy, meaning the heart lacks the fuel it needs to pump blood.
About 85% of individuals with heart disease respond positively to coenzyme Q10 supplementation and significant improvements to their heart health. However, ~10-15% do not see any improvements from the addition of coenzyme Q10. Researchers have learned the “missing link” for these individuals is L-carnitine. The combination of L-carnitine with Coenzyme Q10 is needed for some individuals to experience the additional energy boost and improved heart function.
Signs of improvements many individuals see from a combination of L-carnitine and Coenzyme Q10 include better color, easier breathing, and less difficulty with exertion activities.

Heart Healthy Tips
Heart Disease – Use Vitamin C to Decrease Heart Disease Risk
A new Norwegian study – Diet and Omega 3 Fatty Acid Intervention – found individuals who increased their intake of fruits and berries decreased carotid artery thickening (atherosclerosis – hardening of the arteries), which leads to increased risk of heart disease.
The study followed over 560 men with an average age of 70 years-old for three years. Throughout the three years carotid artery thickness was measured and food intake was assessed via food-frequency questionnaires. Participants who increased vitamin C rich foods, such as fruit and berries, along with a Mediterranean diet plan had reduced arterial thickening. The more vitamin C the less the thickening.
The study concluded that even the elderly can make diet changes and see positive health benefits. We’ve known that fruits are an essential part of a heart healthy diet plan and this diet re-emphasizes that point.

Heart Attack Signs for Women – Prevent Cardiovascular Disease
Here’s another question and answer from my February interview with Dr. Cynthia Shelby-Lane regarding heart attack signs for women. Read Dr. Shelby-Lane’s answer to learn about women cardiovascular disease.
Lisa Nelson RD: For women the signs of a heart attack are more subtle. What should women watch for? If everyone responded to every arm/jaw/chest/indigestion/feeling “not quite right” symptom, they’d never leave the ER!
Dr. Shelby-Lane: The female heart often is misdiagnosed.
True or false: Every year, more women die of heart disease than men.
The answer is true, but if you didn’t know it, you’re not the only one. In a survey of 500 physicians led by preventative cardiologist Lori Mosca, M.D, Ph.D., less than 20 percent knew the answer.
When it comes to women and heart disease, ignorance can be deadly. The misconception that heart disease is a “man’s disease” is the main reason women are misdiagnosed, or receive delayed treatment, when experiencing symptoms of heart disease and even a heart attack.
Consider these findings:
In a recent study at Weill Medical College of Cornell University/New York-Presbyterian Hospital, 230 physicians were given hypothetical cases of men and women with identical symptoms of heart disease. Half of the case studies included reports that the patient recently had a stressful experience or felt anxious. When this detail was included, doctors diagnosed heart disease in 56 percent of men compared with just 18 percent of women.
They referred men to cardiologists twice as often as women, and prescribed cardiac medications to almost half of the men, versus a paltry 13 percent of the women. Researchers concluded that in the presence of stress or anxiety, symptoms such as chest pain and shortness of breath were more likely to be attributed to anxiety in women but seen as potential signs of heart disease in men.
Another study at Tufts Medical Center in Boston found that among people who called 911 complaining of cardiac symptoms, women were 52 percent more likely than men to experience delays during emergency medical service care, a potentially critical difference because treatments for a heart attack are typically most effective when given within 1 to 2 hours of the start of the attack.
“We often hear women patients say that their complaints were dismissed or that they were ‘blown off’ by their doctors when they presented with heart disease symptoms,” says Lori Mosca, M.D., Ph.D., director of preventive cardiology at New York-Presbyterian Hospital and professor of medicine at Columbia University Medical Center. “Studies show that there is a gender bias out there that women need to be aware of. Our own research has shown that physicians are likely to label a woman at lower risk for heart disease than a man who has the exact same calculated level of heart disease risk.”
So how can you protect yourself? Dr. Mosca offers these suggestions:
Know your risks for heart disease, such as your waist size, smoking and exercise habits, blood pressure, and cholesterol levels. If you smoke, quit. Talk to your doctor about diet and exercise changes you can make to lower your risks, and, if appropriate, medications that might help you. Try this quick test at home: Wrap a tape measure around your waist right at the level of your belly button (don’t suck in your stomach). If your waistline measures 35 inches or more, you are more likely to have high cholesterol, high blood pressure, pre-diabetes and an increased risk of dying of heart disease than a woman with a normal waist size.
Knowing your family’s history of heart disease is important because if you have a close relative with heart disease or diabetes, you are at higher risk for these conditions, too.
Even if you don’t have symptoms of heart disease, having a strong family history – particularly if a parent died at a young age of a heart attack – may be enough reason to be checked early to catch problems that may not yet be causing symptoms. In 40 percent of people that develop heart disease, sudden death is the first symptom.
Learn the unique symptoms of women cardiovascular disease.
Chest pain is the most common symptom of heart problems in both men and women, but women are much more likely to also experience subtle symptoms such as headaches, nausea and upset stomach, jaw or neck pain, shortness of breath and generalized fatigue.
Get help immediately. “Research shows that women tend to call for help later than men do, possibly because they don’t recognize these atypical symptoms as signaling heart troubles, or possibly because their tolerance for pain is greater,” says Dr. Mosca. If you have symptoms and think you might be having a heart attack or stroke, don’t delay; call 911.
Have a checkup annually. Report any suspicious symptoms and don’t let your doctor dismiss your concerns. If you have two or more risk factors and you are over the age of 50, a stress test can give more clues to your heart health. If the stress test shows signs of potential heart problems, further tests can be ordered.
Get a second opinion. If you feel your doctor is not taking your concerns seriously don’t hesitate to find a new doctor.
Lisa Nelson RD: Okay, this was a fantastic answer and I appreciate the detail, but I want to clarify. Are you saying if a woman experiences chest pain and an additional symptom, such as headache, nausea, or shortness of breath they should contact their MD immediately; but if it’s just shortness of breath by itself or just neck pain, not such a concern, monitor and watch for any changes. Is that correct?
Dr. Shelby-Lane: If a woman experiences chest pain along with symptoms such as on-going headaches, nausea, fatigue, and shortness of breath, they should contact their doctor immediately and/or go to the emergency room, especially if these symptoms are of sudden onset. Symptoms such as shortness of breath, fatigue and neck pain may also be subtle indicators of heart disease and most women may dismiss these symptoms and never mention them to their doctor, thereby, missing the opportunity to diagnose an underlying heart problem.

Heart Health – Are Omega 6's Good or Bad?
I and other experts so frequently discuss omega 3 fatty acids and the health benefits that you may think all other types of fat are “bad”. That’s not the case. There are many types of heart healthy fats, including omega 6 fatty acids. At least 5-10% of your daily calories should come from omega 6 fatty acids. Some sources of omega 6’s are safflower, sunflower, and soybean oils. Replacing unhealthy fats in your diet with heart healthy unsaturated fats (such as omega 6’s) can decreased coronary heart disease by 24%.
The problem comes from our diets containing too much omega 6. The typical American diet is very high in omega 6 fatty acids. This leads to problems with inflammation when the ratio of omega 3 to omega 6 intake is drastically distorted and is why you don’t hear experts recommending you increase omega 6’s in your diet. You probably have more than enough already and need to work on balancing your omega 6’s with omega 3’s to promote optimal heart health.

Reduce Heart Failure with Weight Loss and Activity
The Physician’s Heart Study followed over 21,000 between the ages of 40 and 84 for over 20 years. They found a significant link between weight, activity, and heart failure I want to share with you.
Both weight and physical activity were independently linked to risk of heart failure.
Weight
Having a high BMI increased heart failure risk in both active and sedentary men. For every additional 7 pounds on a man 5 foot 10 inches tall, risk for heart failure increased 11%.
Physical Activity
Vigorous physical activity reduced heart failure risk in lean, overweight, and obese men. Men that exercised vigorously only 1-3 times a month reduced their heart failure risk 18%. The more frequent and vigorous the exercise the greater the benefit. Very active men, exercising vigorously 5-7 days per week reduced heart failure risk 36%.
The combined risk of obesity and physical activity is substantial. When compared to lean men who were vigorously active 1-3 each month risk of heart failure increased 19% for men that were lean (BMI less than 25), but inactive, 49% in overweight active men, 78% in overweight inactive men, 168% in obese active men, and 293% in obese inactive men.
Key point I want you to take from this post:
This study shows a little activity has substantial benefits. By being vigorously active just 1-3 days each month you can cut your risk 18%.
Get moving!

Heart Disease – Link between Temperament, Personality, and Heart Disease Risk
Lisa Nelson RD: What role does temperament/personality play in a person’s heart disease risk?
Dr. Shelby-Lane: Temperament and personality have a definite effect on blood pressure and on heart disease. This is a great question and it has been studied by the experts, as you will note in the following excerpts. Heart disease consists of congenital abnormalities, arrhythmias, lipid abnormalities acquired and congenital, functional and physiologic problems, risk factors such as diabetes and metabolic syndrome, structural disease and valvular problems, heart failure, acquired disease such as coronary artery disuse, and infectious diseases along with diseases related to blood vessel structure. Again, anxiety, stress, and stress related disorders can have an effect on major hormones, heart rate and heart health and heart disease. Nutritional abnormalities can also affect heart performance.
New research suggests that people who suffer from panic attacks are at increased risk of developing heart disease.
Why people who suffer from panic attacks should be at increased risk of developing heart disease is unclear. According to the study, authors put forward several theories, one being that panic disorders might trigger nervous system changes which could promote the clogging of arteries. Another theory is that people may have been misdiagnosed as having panic attacks when they actually have coronary heart disease. “Clinicians should be vigilant for this possibility when diagnosing and treating people presenting with symptoms of panic,” said Dr Walters.
Study results have shown that people with depression are at increased risk of heart attack and heart failure because they are less likely to be active.
Scientists have known for some years that people who are depressed are at increased risk of heart attack and other cardiac events, however the reason why this should be has remained unclear. However, according to results of a study by Mary A Wooley and colleagues, the increased risk is due to behavioral factors.
The researchers analyzed data obtained from 1,017 people with heart disease, 199 of which had symptoms of depression. Results showed that 10% of depressed participants had a cardiac event (e.g. heart attack, heart failure, stroke, transient ischemic attack) during the study period, compared to just 6.7% of non-depressed participants, meaning that depressed participants were 50% more likely to have a cardiac event. However, results also showed that depressed participants were more likely to smoke, were less likely to take their medications as prescribed, and were less physically active. After the researchers factored these behaviors into their calculations the risk of a cardiac event in depressed participants was similar to that in non-depressed participants.
