Statin Guidelines Flawed

The American College of Cardiology (ACC), the American Heart Association (AHA) and the National Heart, Lung and Blood Institute (NHLBI) proposed guidelines for prescribing statin drugs to prevent heart attacks. The old rule was to prescribe statins whenever a person's bad LDL cholesterol is greater than 100 mg/dL

How Diet Can Lower High Blood Pressure

Changes in diet should be the first strategy for anyone with high blood pressure, but most people will need to make drastic changes in their eating habits to succeed. Scientists at the National Institutes of Health have shown why the DASH diet lowers high blood pressure to normal in more than 80 percent of...

Blood Pressure During and After Exercise

Your blood pressure usually rises as soon as you start to exercise and drops a little bit while you exercise at the same intensity. However, as you continue to increase the intensity of exercise, your blood pressure usually rises higher and higher.

Gluten Lowers Cholesterol

Before you jump on the bandwagon of avoiding gluten, consider its benefits as well as potential problems. People who are gluten-intolerant should avoid wheat, barley, rye and probably oats (because of potential cross-contamination). Your doctor can do tests to see whether you are one of the small minority who need to avoid gluten. Otherwise, consider a study from the University of Toronto which showed that a high-gluten diet helps to lower oxidized LDL cholesterol, triglycerides and uric acid.

Alcohol and Heart Attacks

Moderate drinking does not appear to prevent heart attacks. An analysis of 45 studies of relationships between heart attacks and alcohol consumption reports that the studies that associated moderate drinking with reduced heart attack rates are flawed.

High HDL Cholesterol May Not Protect You from a Heart Attack

Several recent studies show that high levels of HDL cholesterol are not always associated with preventing heart attacks. Today, doctors depend far more on the results of your LDL cholesterol test and how much plaque you have in your arteries.

Statin Side Effects

Statins are widely used to help prevent heart attacks, but a new study shows that the same process that causes this class of drugs to reduce heart attack risk can also increase memory loss, muscle problems, joint pains and diabetes (American Journal of Physiology - Cell Physiology, July 29, 2015). Progression to a Heart Attack Susceptibility...

Triglyceride/HDL Ratio Predicts Heart Attacks, Diabetes

Two blood tests that are done during routine physical exams can be used to predict whether you are at increased risk for a heart attack. It's called the triglyceride/HDL ratio, calculated by dividing your triglycerides number by your HDL number.

Cholesterol Absorbed from Food

Having high blood levels of cholesterol increaes your chances of getting a heart attack, but your blood cholesterol level is influenced far more by how many calories you eat than by how much cholesterol is in the food you eat.

How Soluble Fiber Helps to Prevent Heart Attacks

Forty percent of deaths in the United States are from heart disease, which kills more than 400,000 people each year. Soluble fiber (from beans, oats, peas, barley, nuts, fruits and vegetables) reduces high blood levels of Low-Density Cholesterol (LDL), one of the strongest predictors of heart attack risk

Cholesterol Guidelines

The current cholesterol guidelines recommend that everyone should have a blood level of the bad LDL cholesterol below 100. If you live in Canada, divide the American number by 40.

Questions About Stents

A recent study suggests that stents placed in arteries leading to the heart have not been shown to cure chest pain (Lancet, Nov 2, 2017). Placing stents in people who have heart pain from narrowed arteries and giving them medication is not more effective in relieving pain than just giving them medication and no stents. Stents do help to prevent the heart muscle from dying when put in place within the first few hours after the start of a heart attack.

Red Yeast Rice Pills

People who take red yeast rice pills to lower their cholesterol levels may not be getting their expected protection against suffering a heart attack. North Americans spend an estimated 40 million dollars a year on these pills.

Recovery Heart Rate

A study in the New England Journal of Medicine showed that one of the best tests to predict your risk for having a heart attack is your Recovery Heart Rate. Recovery heart rate is a measure of fitness and a slow recovery from exercise means that you are out of shape. The study really shows...

Arteriosclerosis is Reversible

More than forty years ago, Dr. Robert Wissler of the University of Chicago showed that arteriosclerosis is reversible in animals. Since then, hundreds of papers have shown that it is reversible in humans, even those who have already had heart attacks.

Slow Heart Rate

A slow pulse rate in athletes usually means a strong heart, but in non-athletes, it can mean heart damage. Athletes often have pulse rates below 60 because their hearts are strong enough to pump large amounts of blood with each beat and therefore don't have to beat as often.

Predict Your Heart Attack Risk

Heart attacks are usually caused by an unhealthful lifestyle and are prevented far more effectively by lifestyle changes than by drugs. A healthful lifestyle can prevent more than 80 percent of heart attacks

Insulin Resistance Predicts Heart Attacks and Diabetes

An article written by two highly-respected physicians and an investigative reporter concludes that, "Emerging evidence shows that insulin resistance is the most important predictor of cardiovascular disease and type 2 diabetes" .

Mitral Valve Prolapse

One in ten Americans suffers from mitral valve prolapse and the vast majority have no symptoms and will never know that they have it. Valves are located in your heart to keep blood from backing up. With aging, some of these valves can stretch and fail to close completely, so they allow a small...

NSAIDs May Increase Heart Attack Risk

Millions of people take over-the-counter NSAID pain medicines when they have a headache, fever, chills, joint pain or various other aches and pains. A new study shows that NSAIDs are associated with increased risk for heart attacks.

High-Plant Diet Lowers Blood Pressure

More than 90 percent of North Americans will develop high blood pressure. A new study shows that a diet high in potassium appears to protect teenagers from high blood pressure in adulthood, while a low-salt diet has no effect (JAMA Pediatr, June 2015;169(6):560-568). A high-potassium and low-salt diet is achieved by eating mostly plants,...

Can Your Cholesterol be Too Low?

Almost everyone agrees that having total blood cholesterol levels above 250 is likely to shorten your life and markedly increases your chances of suffering a heart attack, unless you have a very high HDL (which is good). Other studies also show that people with very low cholesterol are at increased risk for cancer of the stomach, esophagus, liver and colon, but it looks like the incubating cancers cause the low cholesterol, rather than a low cholesterol causing the cancers.

Exercise lowers homocysteine

A regular exercise program helps to lower high blood levels of homocysteine, according to a study from multiple medical centers (European Journal of Applied Physiology, November 2006). High blood levels of homocysteine increase your risk for heart attacks, but at this time, nobody knows why. More than 200 papers show high blood levels of...

Angioplasty’s Questionable Results

Angioplasty may not boost survival for heart disease patients. A 15-year follow-up shows that those who have had angioplasties do not live longer than those who received just medication. This supports other studies that have shown that some angioplasties should not have been done

The Hidden Cause of Many Heart Attacks

More than 40 percent of people who have had heart attacks are diabetic and these patients are the ones who are most likely to die from their heart attacks (Lancet, 2002; 359: 2140-44). Three tests are commonly used to diagnose diabetes: fasting blood sugar, blood sugar level two hours after eating, and HbA1c, a measurement of how much sugar is attached to cells.

Reducing Alcohol Intake May Help to Prevent Heart Attacks

Contrary to what you may have heard previously, it now appears that any amount of alcohol can be harmful. Researchers reviewed more than 50 studies involving more than 260,000 people and concluded that reducing alcohol consumption helps to prevent heart attacks, whether a person is a light, moderate or heavy drinker

Dangers of Shoveling Snow

What's the most common cause of winter-time heart attacks, shoveling snow or breathing cold air? A study in Toronto showed that most heart attacks occur on the day after a snowfall, not on the coldest days. Your heart has to work two and a half times harder to pump blood through your arms than...
