A good way to lower blood pressure may only be a breath away
Simply spending a few minutes a day taking slow, deep breaths may help to bring high blood pressure down. A scientist at the National Institutes of Health thinks how we breathe may hold a key to how the body regulates blood pressure -- and that it has less to do with relaxation than with breaking down salt.

Not enough sleep may lead to high blood pressure
In a special online report on May 3, 2006, Hypertension, the journal of the American Heart Association, researchers monitored the health of nearly 5,000 adults over 8 to 10 years. None had high blood pressure at the start of the study. People who reported that they slept fewer than five hours each night doubled their risk for developing hypertension, compared with people who reported sleeping seven or eight hours a night.

Plavix doesn't help, may harm - Aspirin alone is best
Adding the blood-thinning drug Plavix, the world's fourth-biggest-selling drug, to a daily dose of aspirin does not lower the risk of death, heart attack or stroke in high-risk patients and may even increase the risk of severe bleeding and death in patients with risk factors for heart disease, researchers told the American College of Cardiology meeting in March 2006.

New 'low fat' study is flawed
Headlines and news articles are giving people the false impression that they can eat their favorite fat foods and still prevent heart disease and cancer. It just isn't so.

Don't overlook Sweat as a good heart attack indicator
Sweating under exertion or in hot weather is normal. However, sweating along with symptoms such as discomfort in the chest, arm, neck or jaw may indicate a heart attack.   Researchers from the University of Chicago, who presented this at the American Heart Association's annual meeting in December 2005, have determined that sweating is a frequently overlooked early sign of a heart attack. Those who realize they are having a heart attack early are much more likely to seek prompt treatment and survive.
"We can stop a heart attack during the process, but you have to get to the hospital first," explained Catherine Ryan, research assistant professor of medical surgical nursing. "The real push for improved survival is to get them there early."

HDL and Statins, a new study
The November 4 issue of Circulation includes a a report of a study of nearly 6,000 men from 70 to 82 discussing the renewed importance of HDL levels, more than LDL concerns - and the use of statins to lower inflammation, an established precursor of heart desease.

What does 'low carb' really mean and is it heart healthy?
The marketing phenomenon (that's mostly what it is) of so-called low-carb foods seems to reach everywhere. But there's no standard for this claim and in many cases these foods may be more harmful than beneficial. The Mayo Clinic offers a clear and easy to understand explanation, including the difference between glycemic index and glycemic load. To read it, click here.

Aspirin prevents cardiovascular disease
The beneficial effects of aspirin in secondary prevention of cardiovascular (CV) and cerebrovascular disease have been well established since the 1970s. The U.S. Preventive Services Task Force (USPSTF) recommends that even patients without known cardiovascular disease but with risk for a CV event be treated with 81mg of aspirin daily. The task force gave this intervention its strongest recommendation. The data suggest that aspirin reduces the risk of CV events by 28 percent. For a full summary of the evidence, click here.

Do antioxidant vitamins help or harm those with coronary artery disease?
We really can't say. But more controversy about vitamins and heart disease is sure to come from a small study of 299 postmenopausal women published in the April 2004 edition of the journal Diabetes Care.
The women were given 800 IU of vitamin E and 1000 mg vitamin C daily for 2.8 years. Angiograms of the coronary arteries done at the beginning and end of the study measured changes in the diameter of their arteries. Those with one type of the haptoglobin gene showed a significant benefit, those with another type showed no change, and a third type had worsening of their arteries.
Haptoglobin is a protein in the blood that binds to free hemoglobin and returns it to the liver for metabolism. Most people do not have the form of haptoglobin that was in the women who benefited from antioxidants. Only 14 percent of Caucasians and 26 percent of African-Americans are that type.

Study Clarifies Heart Effects of Aspirin Alternatives
Non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen may reduce the risk of heart attacks, but they may not help people who are already taking aspirin, according to a new study in the March 17, 2004 issue of the Journal of the American College of Cardiology. For a summary, click here.


Atkins-type diet causes ketosis - raises bad cholesterol,lowers good
Very low carbohydrate diets, such as the Atkins Diet, give rise to ketosis, a condition where when the body burns fat, the byproducts of that metabolism go into the bloodstream and the urine. A study in the August 20, 2003 edition of JAMA, the Journal of the American Medical Association showed children fed a ketogenic diet for 24 months significantly increased total and LDL cholesterol as well as triglycerides; however HDL cholesterol dropped significantly - the opposite of what is needed to prevent or reverse heart disease.

Statins and low cholesterol - do they cause problems?
Tales that low cholesterol and statins cause depression, anxiety, suicide don't hold up. A study published in the August 20, 2003 issue of the Journal of the American College of Cardiology indicates that continual use statins (which usually results in lower cholesterol) actually lowers depression, hostitility and anxiety. For an abstract of the article, click here.


Risk factors you can control, not heredity, cause most heart disease.
In direct contrast with popular belief, 80% to 90% of patients with coronary heart disease have conventional risk factors (smoking, high cholesterol, high blood pressure and diabetes). A report in the August 20, 2003 issue of JAMA, the Journal of the American Medical Association reviewed more than 100,000 people in 14 studies over ten+ years. To read the abstract, click here.


Antioxidants and heart disease- children's study
In a study reported in the August 12, 2003 issue of Circulation, the journal of the American Heart Association, researchers show that moderate doses of antioxidant vitamins can reverse endothelial dysfunction, a condition in which the blood vessels aren't flexible enough to expand and contract in response to changes in blood flow, also an early sign of atherosclerosis. The subjects were children with familial high cholesterol, but it is promising information for anyone with a similar situation.

Grazing can keep you slimmer and lower heart risk
A study in the July 2003 issue of the American Journal of Epidemiology indicates that those who skip meals or eat out regularly are more than 4½ times more likely to be obese, which places them at proportionately higher risk for heart disease. Those who eat more frequently (grazing), reduce their risk in half. For a summary of the article and a link to the journal abstract click here.


Does Homocystiene make a difference?
The relationship between homocystiene and heart disease is far from clear for persons taking statins. In a study published in the June 18, 2003 edition of the Journal of the American College of Cardiology the authors conclude that folates can lower homocysteine levels, but doing that doesn't decrease mortality and cardiovascular disease events.

Caution on Reports about Low-carb vs Low-fat for Weight Loss
Recent media headlines have claimed that a a new study "proves" that low carb diet is "better" than a low fat one. The study had an extremely small sample, did not show long term gains and the media misquoted or omitted much of the authors' conclusions. Less than 80% of the women completed the study.

In the April 2003 issue of the Journal of Clinical Endocrinology and Metabolism, 53 obese women (BMI average=33.6) were divided into to two groups, one fed a low carbohydrate diet, the other a low fat diet.

Women eating a low-carbohydrate diet temporarily (6 months) lost more weight than those on a calorie-restricted low-fat diet even though the calorie load was similar.

The authors warn, however, that "these results should not be extrapolated to subjects with cardiovascular risk factors at baseline, and that longer studies are needed. This study suggested some recidivism during the last three months, and low calcium and fiber intake could prove to be problematic over longer periods". For an abstract of the article, click here.


Fiber Intake Can Reduce Heart Disease Risk in Seniors

Homocysteine, Folates and Heart Disease
In an effort to determine if there is a cause and effect relationship between homocystyeine and heart disease, and if folates (folic acid) have a significant effect on this, the British Medical Journal, recently published a meta-analysis of 92 studies involving 20,000 people.

According to this analysis, taking 800 mcg of folic acid daily (twice the amount commonly recommended) could reduce heart disease by 16 percent and stroke and blood clots by 25 percent.

This provides strong evidence of a relationship between serum homocysteine and heart disease, but it does not offer proof that one is caused by the other. Nevertheless, some some experts and much of the popular press erroneously cite this report as proof of a causal relationship. Much more research is needed to establish this.

Australian Blood Pressure Medication Study
New research published on February 13, 2003 in the New England Journal of Medicine appears to contradict a widely publicized study that concluded that cheap, old-fashioned diuretics should be the first drug given to people with high blood pressure.

Sleep Duration and Heart Disease
A 10-year study of nearly a thousand women published in the January 27, 2003, issue of the journal Archives of Internal Medicine reported that too little or too much sleep slightly raises the incidence of heart disease-related events (heart attack, death, etc). Popular media have drawn some alarming and misleading conclusions, not in the journal research report. To read the journal's actual abstract, click here
