Common dietary fat and intestinal microbes linked to heart disease

A new pathway has been discovered that links a common dietary lipid and intestinal microflora with an increased risk of heart disease, according to a Cleveland Clinic study published in the latest issue of Nature.

The study shows that people who eat a diet containing a common nutrient found in animal products (such as eggs, liver and other meats, cheese and other dairy products, fish, shellfish) are not predisposed to cardiovascular disease solely on their genetic make-up, but rather, how the micro-organisms that live in our digestive tracts metabolize a specific lipid -- phosphatidyl choline (also called lecithin). Lecithin and its metabolite, choline, are also found in many commercial baked goods, dietary supplements, and even children's vitamins.

The study examined clinical data from 1,875 patients who were referred for cardiac evaluation, as well as plasma samples from mice. When fed to mice, lecithin and choline were converted to a heart disease-forming product by the intestinal microbes, which promoted fatty plaque deposits to form within arteries (atherosclerosis); in humans, higher blood levels of choline and the heart disease forming microorganism products are strongly associated with increased cardiovascular disease risk.

"When two people both eat a similar diet but one gets he

Yoga May Also Calm a Dangerous Irregular Heartbeat - US News and World Report

In a small preliminary study, the ancient art of yoga appeared to halve the number of episodes of a potentially dangerous irregular heartbeat known as atrial fibrillation.

Click here to find out more!

Three sessions of yoga a week also improved quality of life, lowering levels of the anxiety and depression which often plagues patients with this condition, according to research to be presented Saturday at the annual meeting of the American College of Cardiology in New Orleans.

"These are exciting results," said Dr. Raul Mitrani, director of the cardiac rhythm device clinic at the University of Miami Miller School of Medicine. Although it didn't cure atrial fibrillation, he added, it did seem to cut the number of "a-fib" episodes.

Study Finds Conflicts of Interest Among Medical Panelists - NYTimes.com

Doctors with private financial conflicts of interest dominated some of the panels that wrote guidelines on cardiovascular health in recent years, according to a medical journal study released on Monday.

Penn Medicine

Dr. James N. Kirkpatrick, the study's senior author.

University of Miami Health System

Dr. Ralph L. Sacco, president of the American Heart Association.

The guideline panels are the select groups of experts who are assigned to evaluate science independently and issue their advice to other doctors on what to do in clinical practice. The guidelines influence medical care, product choice, insurance coverage, government policy and malpractice cases.

The study, published in the Archives of Internal Medicine, found that conflicts of interest were reported by 56 percent of 498 people who helped write 17 guidelines for the American Heart Association and American College of Cardiology, from 2003 through 2008.

Physical activity improves quality of life. American Heart Association, Inc.

Do you want to add years to your life? Or life to your years?

Feeling your best boosts your zeal for life!

The American Heart Association recommends 30-minutes of moderate activity, but three 10-minute periods of activity are almost as beneficial to your overall fitness as one 30-minute session. This is achievable! Physical activity may also help encourage you to spend some time outdoors. Sunlight on your skin helps your body produce vitamin D, which brings many added health benefits.

Here are some reasons why physical activity is proven to improve both mental and physical health.

Physical activity boosts mental wellness.

Regular physical activity can relieve tension, anxiety, depression and anger. You may not only notice a "feel good sensation" immediately following your physical activity, but most people also note an improvement in general well-being over time during the weeks and months as physical activity becomes a part of your routine.

Exercise increases the flow of oxygen which directly effects the brain. Your mental acuity and memory can be improved with physical activity.

Physical activity improves physical wellness.

Sleep deprivation 'can cause strokes' | News | Nursing Times

Stroke or heart disease susceptibility is dependant on how much you sleep you get, a new study has suggested.

A Warwick Medical School study has discovered that prolonged sleep deprivation can have a seriously adverse effect on cardiac health.

The research team linked a lack of sleep to strokes, heart attacks and cardiovascular disorders which can often cause early death.

Professor Cappuccio and co-author Dr Michelle Miller examined evidence from more than 470,000 participants across eight countries, including Japan, the US, Sweden and the UK.

Professor Francesco Cappuccio said: “If you sleep less than six hours per night and have disturbed sleep you stand a 48% greater chance of developing or dying from heart disease and a 15% greater chance of developing or dying from a stroke.

“The trend for late nights and early mornings is actually a ticking time bomb for our health so you need to act now to reduce your risk of developing these life-threatening conditions.”

Dr Miller added chronic short sleep produces hormones and chemicals in the body, which increases the risk of developing heart disease and strokes, plus other conditions such as high blood pressure and cholesterol, diabetes and obesity.

Prevention.com - 28 Days to a Healthier Heart - Prevention

    Did you know that more than 41 million women in America have heart disease? And that more women than men will die from it? In fact, it’s the leading health problem that kills women (not cancer—a common myth).

    But the good news is that just five lifestyle guidelines—moderate alcohol, a healthy diet, daily exercise, normal body weight, and not smoking—can cut your heart attack risk by a whopping 92%, according to a Swedish study of more than 24,000 women. Incorporating just the first two into your routine cuts your risk by more than half.

    The 28 tips that follow are designed to help you get started. Try one a day for a month, and then stick with as many as you can for the long haul.

Myths About Heart Disease - Nursing Link

Anita Manning | USA TODAY

February 01, 2011

Imagine hearing news of a catastrophe causing the deaths of 2,200 Americans every day — an average of one every 39 seconds.

A plague? Nuclear fallout?

It’s heart disease, which includes diseases of the heart and circulatory system. The No. 1 killer stalking the world, cardiovascular diseases cause more deaths than all forms of cancer combined.

It’s an equal-opportunity destroyer, although it does have a preference for people of color and those over 65. But no age, race or economic class is immune.

“There’s a lack of awareness of what ideal cardiovascular health really is,” says Ralph Sacco, president of the American Heart Association. While 35% of people surveyed say they’re in good health, when quizzed about seven major health factors — diet, activity level, blood pressure, cholesterol, weight, blood sugar and smoking status — only about half of 1% hit all the targets for good health, he says. “People think they’re healthier than they are,” he says, making it less likely that they’ll take steps to reduce their heart risks.

Do Registered Nurses Need a BSN?

RegisteredNurseMost potential Registered Nurses always ponder the same age old question, "Do I need BSN or should I just get a ADN?"

Learn about degree programs here.

Sacco and other heart experts highlight 10 myths of heart disease:

Practice Guidelines: Managing Chronic Heart Failure - Mosby' s Nursing Suite

With the U.S. population aging, chronic heart failure is on the rise. Now healthcare professionals must diagnose and manage this complex, life-threatening syndrome more effectively than ever. To help, the American College of Cardiology and American Heart Association provide complete practice guidelines for the four stages of heart failure.

The American Heart Association has identified these four stages of heart failure (HF), which complement the NYHA classifications:
  • Stage A: At high risk for HF but no structural heart disease or HF symptoms
  • Stage B: Structural heart disease but no HF signs or symptoms
  • Stage C: Structural heart disease and prior or current HF symptoms
  • Stage D: Refractory HF that requires specialized interventions

According to the guidelines, possibly the most effective and least followed general measures are close attention and follow-up. These require regular assessment, patient teaching, monitoring of adherence to the plan of care, and evaluation of the patient’s response. To help you and your colleagues align your practice with current guidelines, the following list summarizes teaching for patients with Stage C heart failure.

Men's Health: MedlinePlus

While the life-expectancy gap between men and women has decreased, it's no secret that men still need to pay more attention to their bodies. Several things work against men. They tend to smoke and drink more than women. They don't seek medical help as often as women. Some men define themselves by their work, which can add to stress.

There are also health conditions that only affect men, such as prostate cancer and low testosterone. Many of the major health risks that men face – like colon cancer or heart disease - can be prevented and treated with early diagnosis. Screening tests can find diseases early, when they are easier to treat. It's important to have regular checkups and screenings.

Heart Advice from a Cardiologist - Prevention.com

I'm 62 and, thankfully, have never been hospitalized, nor can I remember calling in sick. I still work 12-hour days, walk the golf course, hit the heavy bag, and, not too long ago, even played ice hockey. Other than some minor colds, flus, and heartburn, I have been very healthy, and I take no regular medications. How I've managed this isn't a secret. My philosophy is in my books. But for this special issue of Prevention, I want to summarize it for you--what I eat, how I exercise and beat stress, even my own advice that I struggle with. Here's my personal Rx--feel free to make it your own:


Eat three squares and a snack: I start most days with a three-egg omelet (one yolk and whites) and some green tea with a scoop of Benefiber (a natural fiber supplement). For lunch, I usually order baked salmon and grilled veggies from a nearby restaurant. I never eat fast food. And for dinner, my wife, Sari, typically makes fish or chicken with veggies. We eat little starch at home. If I get hungry during the day or when I'm traveling, I'll have a mozzarella stick, fruit, wasabi-coated soy nuts, other nuts, or a high-fiber bar.

Obesity Alone Raises Risk of Fatal Heart Attack, Study Finds

Obese men face a dramatically higher risk of dying from a heart attack, regardless of whether or not they have other known risk factors for cardiovascular disease, a new study reveals.

The finding stems from an analysis involving roughly 6,000 middle-aged men, and it suggests that there is something about carrying around excess weight that contributes to heart disease independent of risk factors such as high blood pressure, diabetes, high cholesterol and arterial disease.

What exactly that something is, however, remains unclear, although the researchers suggest that the chronic inflammation that typically accompanies significant weight gain might be the driving force behind the increased risk.

"Obese, middle-aged men have a 60 percent increased risk of dying from a heart attack than non-obese middle-aged men, even after we cancel out any of the effects of cholesterol, blood pressure and other cardiovascular risk factors," noted study author Jennifer Logue, a clinical lecturer of metabolic medicine with the British Heart Foundation's Cardiovascular Research Centre at the University of Glasgow, in Scotland. "This means [that] obesity itself may be causing fatal heart attacks through a factor that we have not yet identified."

Logue and her colleagues report their observations in the Feb. 15 online issue of Heart.

To explore the subject, the authors spent nearly 15 years tracking 6,082 male patients who were diagnosed with high cholesterol but had no history of either heart disease or diabetes.

Over the study period, the research team noted 214 heart disease fatalities, along with another 1,027 heart attacks and/or strokes that did not result in death.

Patients With Blocked Carotid Arteries May Not Need Stroke Screening | National Nursing News

Patients with blocked neck arteries need screening for stroke risk only if they have other risk factors, according to new guidelines from the American Heart Association/American Stroke Association, American College of Cardiology and other groups.

A committee of stroke prevention specialists issued the guidelines after agreeing there is not sufficient evidence of benefit from widespread screening. The members hope the guidelines provide new information to help clinicians determine treatment approaches for their patients.

Screening is useful “if your doctor hears abnormal blood flow when listening to your [carotid] arteries, or if you have two or more risk factors for stroke (such as high cholesterol or a family history),” said Jonathan L. Halperin, MD, co-chairman of the writing committee and professor of medicine at the Mount Sinai School of Medicine in New York, in a news release.

Risk factors for stroke include age, family history of stroke, high blood pressure, high blood cholesterol, diabetes, obesity, atrial fibrillation, physical inactivity, sickle cell disease and other heart or blood vessel diseases.

The committee also issued recommendations regarding carotid endarterectomy and carotid stenting, two procedures for treating arteries. Both procedures are reasonable and safe, according to the committee, when arteries are more than 50% blocked.

“The guidelines support carotid surgery as a tried-and-true treatment for most patients,” said Thomas G. Brott, MD, committee co-chairman and professor of neurology and director of research at the Mayo Clinic campus in Jacksonville, Fla.

“However, for patients who have a strong preference for less invasive treatments, carotid stenting offers a safe alternative. Because of the anatomy of their arteries or other individual considerations, some patients may be more appropriate for surgery and others for stenting.”

This will be good news for people for who Carotid Endarterectomy has been suggested.

CDC Features - February is American Heart Month

About every 25 seconds, an American will have a coronary event.

Heart disease is the leading cause of death in the United States and is a major cause of disability. The most common heart disease in the United States is coronary heart disease, which often appears as a heart attack. In 2010, an estimated 785,000 Americans had a new coronary attack, and about 470,000 had a recurrent attack. About every 25 seconds, an American will have a coronary event, and about one every minute will die from one.1

The chance of developing coronary heart disease can be reduced by taking steps to prevent and control factors that put people at greater risk. Additionally, knowing the signs and symptoms of heart attack are crucial to the most positive outcomes after having a heart attack. People who have survived a heart attack can also work to reduce their risk of another heart attack or a stroke in the future. For more information on heart disease and stroke, visit CDC's Division for Heart Disease and Stroke Prevention.

Diseases and Conditions That Put Your Heart at Risk

Other conditions that affect your heart or increase your risk of death or disability include arrhythmia, heart failure, and peripheral artery disease (PAD). High cholesterol, high blood pressure, obesity, diabetes, tobacco use, unhealthy diet, physical inactivity, and secondhand smoke are also risk factors associated with heart disease. For a full list of diseases and conditions along with risk factors and other health information associated with heart disease, visit the American Heart AssociationExternal Web Site Icon.

Know Your Signs and Symptoms

Some heart attacks are sudden and intense; however, most heart attacks start slowly, with mild pain or discomfort. Often people affected aren't sure what's wrong and wait too long before getting help. Here are signs

CDC: U.S. Healthcare System Can Do Better in Treating CVD | All Sites Nursing News

The Centers for Disease Control and Prevention cites issues with the U.S. healthcare system as part of the reason for the extent of cardiovascular disease in the country.

In a report released Tuesday, the CDC said two-thirds of adults with high cholesterol and half with hypertension do not receive effective treatment.

"Although we're making some progress, the United States is failing to prevent the leading cause of death — cardiovascular disease — despite the existence of low-cost, highly effective treatments," said CDC Director Thomas Frieden, MD, MPH.

"We need to do a better job improving care and supporting patients to prevent avoidable illness, disability and death."

For many people, according to the CDC, merely having healthcare coverage is not sufficient.

Medical News: Cut Daily Salt Intake to 1,500 Mg, AHA Says - in Cardiovascular, Hypertension from MedPage Today

Daily intake of salt should be limited to 1,500 mg for all Americans, according to an advisory statement from the American Heart Association (AHA).

"The 2020 goal of the American Heart Association is to improve the cardiovascular health of all Americans by 20% while continuing to reduce deaths from [cardiovascular disease] and stroke by 20%," Lawrence J. Appel, MD, of Johns Hopkins, and colleagues wrote online in Circulation.

Two key components of improving cardiovascular health are population-wide lowering of blood pressure below 120/80 and reducing sodium chloride intake below 1,500 mg per day, observed AHA president Appel.

Action Points  --->
  • Note that the American Heart Association states that two of the key metrics for ideal cardiovascular health are a blood pressure of 120/80 mm Hg and sodium consumption of 1500 mg/day.

  • Note further that in this advisory, the AHA reviews the evidence for the benefits of reduced sodium intake and issues a call to action.
  • The evidence linking salt intake with blood pressure -- and the major adverse outcomes of heart disease, stroke, and kidney disease -- is "impressive," wrote the authors of the advisory.

    That evidence includes more than 50 trials assessing the blood pressure effects of salt, as well as a meta-analysis showing that cutting salt intake by about 1,800 mg per day lowered blood pressure by 5 mm Hg systolic and 2.7 mm Hg diastolic.

    Various studies also have compared the benefits and outcomes of a number of different sodium reduction goals. Notably, reducing salt consumption also can help prevent the blood pressure increases that come with age, ultimately affecting 90% of adults.

    For Teens, Too Much Sugar Can Be A Heartbreaker : Shots - Health News Blog : NPR

    Teenagers who guzzle a daily bottle of soda are probably not thinking much about their hearts as the sweet stuff runs down their throats.

    Antonio Garcia re-stocks the beverages at The Corner Market in Washington, D.C., in 2010. Study author Jean Welsh says that sweetened beverages tend to be the biggest source of added sugar.

    But a new study suggests they should be. Teens who consume lots of added sugar — usually found in sugar-sweetened beverages — risk heart problems later in life, researchers found.

    This main problem is the sheer volume of sugar American teens consume: 28.3 teaspoons of added sugar a day on average. That makes up a whopping one-fifth of their daily calories, according to Jean Welsh, study author and post-doctoral fellow in pediatric nutrition at Emory University School of Medicine. It works out to an average of 476 calories a day.

     

    Teens who consumed the highest percentage of their calories from added sugar had less of the "good" cholesterol compared with consumers who ate the least sugar. Another finding was that teens who consumed more added sugars also had higher levels of the "bad" cholesterol  and fats called triglycerides.
