Does screening and treating high cholesterol save money? KevinMD.com

by Richard Young, MD
A commenter (I believe a physician) on one of my posts wrote the following: “I can prevent heart attacks and strokes (caused by atherosclerosis – “blockage”) in people (minimal cost) who have no symptoms. If I wait for their heart attack or stroke – it costs a whole lot more.”
The implication is that screening and treating high cholesterol saves money in the long run. Unfortunately, the truth is the opposite. This is an extremely common misconception among most people in healthcare, physicians included. Therefore the American people believe the same thing.
If I give a person a pneumonia shot and that person lives the rest of her life never catching pneumonia, then there is a fair chance I prevented a case of pneumonia. On the other hand, she may not have ever gotten pneumonia any way, therefore the shot was useless. There’s no way to sort that out, but classifying a vaccine as preventing a disease is certainly fair.

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

The five hospital factors that affect heart attack survival, Science Daily

Until now, little has been known about the factors that may influence this variation in death rates. The Yale team reviewed 11 hospitals through interviews and site visits. Those selected were among the best and worst performers, as rated by the federal agency that administers Medicare and Medicaid.

"Previous research looked at whether hospital characteristics like urban location, teaching status, geographical region, and socio-economic status of patients are related to acute myocardial infarction (AMI) mortality rates, but these factors don't explain much of the variation in mortality," said Leslie A. Curry, Ph.D., research scientist at the Yale Global Health Leadership Institute and lead author on the paper. "We were particularly interested in the roles of social interactions and organizational culture, which are difficult to measure using common research approaches like surveys."

Hospitals in the high- and low-performing groups differed substantially in five ways: organizational values and goals, senior management involvement, broad staff presence and expertise in AMI care, communication and coordination, and problem solving.

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.

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.

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.

What to Do During a Heart Attack | Heart Attack Information for Women

Heart Attack Action Plan

Call 9-1-1 for emergency medical care.

Did you know?

Women who call their own doctor before calling 9-1-1 take twice as long to get life-saving treatment.

Calling 9-1-1 is the best and fastest way to get to the hospital. When you notice heart attack symptoms, call 9-1-1 immediately (within five minutes at most). If you call 9-1-1, emergency medical personnel can begin life-saving treatment right away, even before you get to the hospital. Don't drive yourself or have someone drive you unless you have no other choice.
More about why 9-1-1 is the right call »

Heart attack patients who arrive by ambulance tend to be treated faster once they get to the hospital, and every minute counts.

If you try to drive yourself, you could get stuck in traffic or pass out and cause an accident.

Calling your own doctor before calling 9-1-1 only causes delays.

Common problems soon after a heart attack include arrhythmia (a problem with the heart's rhythm that can be caused by damage during a heart attack) and cardiac arrest (when the heart suddenly and unexpectedly stops beating). Emergency medical personnel have the equipment and training to deal with these problems and make sure you get to the hospital safely.

Talk to the 9-1-1 operator and follow their instructions.

Did you know?

The ambulance can find you whether you call 9-1-1 from a land line or your cell phone. If they're equally close, use the land line.

Try not to panic. Take long, deep breaths, stay calm, and speak slowly and clearly. The dispatcher will ask for your name, where you are, and what is wrong. Say: "I think I am having a heart attack." Stay on the line until you are sure the operator has all the information they need.

The 9-1-1 operator may tell you to chew and swallow an aspirin if you are not allergic and don't have any other medical reason not to take it. Never delay calling 9-1-1 to take an aspirin.

How Much Weight Can You Lose By Walking On The Treadmill 45 Minutes A Day? | LIVESTRONG.COM

Exercise is one of the two most commonly used methods for losing weight, with cardiovascular exercise being the most effective form for weight loss. Although such exercises as cycling, running and cross-country skiing are cardiovascular options, walking can be just as valid a choice. It's low-impact, often more enjoyable and accessible without specialized equipment. Walking on a treadmill even eliminates the need to wait for good weather.

Exercise and Weight Loss

If you eat fewer calories than you take in, your body burns fat to access the energy stored in fat cells. Lost fat equals lost weight. Exercise boosts your daily energy needs, meaning you increase the number of calories you burn during the day. You need to do 3,500 calories worth of exercises for each pound you want to lose -- assuming you don't increase how much you eat in response to the extra energy expenditure.

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.

Coffee, sex, smog can all trigger heart attack, study finds, USAToday

A major analysis of data on potential triggers for heart attacks finds that many of the substances and activities Americans indulge in every day — coffee, alcohol, sex, even breathing — can all help spur an attack.

Because so many people are exposed to dirty air, air pollution while stuck in traffic topped the list of potential heart attack triggers, with the researchers pegging 7.4% of heart attacks to roadway smog.
But coffee was also linked to 5% of attacks, booze to another 5%, and pot smoking to just under 1%, the European researchers found.
Among everyday activities, exerting yourself physically was linked to 6.2% of heart attacks, indulging in a heavy meal was estimated to trigger 2.7%, and sex was linked to 2.2%.
The researchers stressed that the risk for heart attack from any one of these factors to a particular person at any given time is extremely small. But spread out over the population, they can add up

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?

Most 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.

Heart Advice from a Cardiologist - Prevention.com

By Arthur Agatston , Arthur Agatston, MD, is a preventive cardiologist and Prevention's "From the Heart Doc." He is also a member of Prevention's medical advisory board.

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.

Carotid Artery Stenosis, American Heart Association

What is carotid artery stenosis or carotid artery disease?

Carotid artery stenosis is the narrowing of the carotid arteries. These are the main arteries in the neck that supply blood to the brain. Carotid artery stenosis, also called carotid artery disease, is a major risk factor for ischemic stroke. (This is the most common form of stroke and is usually caused by a blood clot plugging an artery.)

The narrowing is usually caused by plaque in a blood vessel. Plaque forms when cholesterol, fat and other substances build up in the inner lining of an artery. This process is called atherosclerosis.

How is carotid artery stenosis diagnosed?

Carotid artery stenosis may or may not cause symptoms. A doctor may hear an abnormal sound called a bruit (BROO'e) when listening to the artery with a stethoscope. The stenosis can be easily detected with an ultrasound probe placed on the side of the neck near the carotid arteries. This is called carotid ultrasonography.

How is carotid artery stenosis treated?

Depending on the degree of stenosis and the patient's overall condition, carotid artery stenosis can usually be treated with surgery. The procedure is called carotid endarterectomy. It removes the plaque that caused the carotid artery to narrow. Carotid endarterectomy has proven to benefit patients with arteries stenosed (narrowed) by 70 percent or more. For people with arteries narrowed less than 50 percent, anti-clotting medicine is usually prescribed to reduce the risk of ischemic stroke. Examples of these drugs are antiplatelet agents and anticoagulants.

Carotid angioplasty may be another treatment option. It uses balloons and/or stents to open a narrowed artery.
For stroke information, call the American Stroke Association at 1-888-4-STROKE.

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 Association.

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.

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.

Jacquelyn Martin/AP
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.

OrganizedWisdom Finds Free Experts Make for SEO Success - NYTimes.com

With Demand Media currently planning a high-profile IPO and issues being raised about the impact of “content farms” on search results, there is a lot of attention being paid to the question of content aggregation and its effect on the web. OrganizedWisdom Health, a health-resource service, now believes it’s better — and more profitable — to organize free content rather than pay for low-wage material.
The New York-based startup has spent most of the past four years building up an index of “wisdom cards:” topical health entries that were written by contributors for a small fee. At any given moment, OrganizedWisdom contracted with 100 writers, who covered a wide array of medical topics. But exactly one year ago, the company dropped the paid-content route and embraced a free expert model. So where does the content come from? The startup keeps track of some 5,000 doctors and health experts who use social media, and collects their contributions into wisdom cards.
