Fit people are less likely to suffer a particular form of irregular heartbeat called atrial fibrillation, and a regular exercise program reduces a person's chances of developing atrial fibrillation Extreme endurance exercisers such as bicycle racers, cross country skiers and long-distance runners who compete into their 40s and beyond may be at increased risk for atrial fibrillation
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.
A new review of studies on sugar-added foods shows that people who take in 10-25 percent of their calories from sugared beverages and foods suffer a 30 percent higher risk for heart attacks, compared with people who take less than ten percent of calories from added sugars.
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
In the last ten years, seven million North Americans have spent more than $110 billion to have stents put into the arteries leading to their hearts and the vast majority probably should not have had this surgical procedure in the first place.
If your doctor has told you that you have high blood pressure or that your cholesterol or triglycerides are too high, ask him or her for your numbers. If would like to find out whether you are one of the 80 percent of people who can control high blood pressure, cholesterol and triglycerides with diet alone, follow my SHOW ME! Diet for just two weeks. Then have your doctor re-check your cholesterol, triglycerides and blood pressure. You'll probably also find that you have lost several pounds.
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.
Knowing when to take your blood pressure can help you predict your likelihood of suffering a heart attack. We know that having high blood pressure markedly increases your risk for heart attacks. Blood pressure is usually lowest just before you go to bed at night and when you first wake up in the morning.
Reports from Harvard School of Public Health shows that a diet rich in plants lowers high blood pressure (1,2). It's called the DASH diet (Dietary Approaches to Stop Hypertension.) Other studies show that similar eating patterns lower cholesterol, help to control diabetes and cause weight loss in people who are overweight.
A resting heart rate greater than 80 beats per minute is a strong predictor for future heart attacks, diabetes and even cancer. From 1974 to 2002, 53,322 healthy people were followed at the Cooper Clinic in Dallas, Texas. Those with a resting heart rate lower than 60 beats per minute were far less likely to suffer heart attacks or to die than those with a resting heart rate greater than 80 beats per minute
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
You have two blood pressures: the systolic that measures blood pressure when your heart contracts, and the much lower diastolic reading that measures the pressure when your heart relaxes. When your heart contracts, it pushes a huge amount of blood forward to your arteries. Your arteries are supposed to act like balloons and expand to accept the blood and prevent your blood pressure from rising too high.
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...
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...
Most of the chemicals in your body and in your food are safe, but when many chemicals in your body and foods are oxidized and converted to their oxidized forms they become harmful. Cholesterol is pure and safe for arteries. The cholesterol in fresh meat, fish, eggs and milk is safe. In fact, it functions as an antioxidant that protects your arteries.
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.
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.
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...
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.
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.
It takes only two weeks for a diet to lower cholesterol as much as it is going to do. You lower cholesterol by replacing saturated fats from animals with polyunsaturated or monounsaturated fats from plants, and by restricting refined carbohydrates found in bakery products, pastas and sugar-added foods and drinks. Many doctors think that it...
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...
Your leg muscles function like a second heart to pump fluid from your legs to your heart. When your leg muscles relax, the veins near them fill up with blood. When your leg muscles contract, they compress the veins and squeeze blood up toward your heart.
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...
