If you have pain in your chest, jaw, arm, or neck when you exercise, you could have angina, which is pain caused by reduced blood flow through narrowed arteries leading to your heart. You should check with a doctor as soon as possible. Symptoms of angina can also include feeling lightheaded, over-tired, short of breath or nauseated
If your routine blood tests show that you have high triglycerides (greater than 150 mg/dl), this usually means that you are at high risk for diabetes and all of its side effects, including heart attacks. Your doctor measures blood levels of the bad LDL cholesterol to predict your susceptibility to suffering a heart attack, but triglycerides are just as important in predicting your risk for a heart attack, diabetes and premature death.
Virtually all doctors agree that stents can save lives if used within three hours of the start of a heart attack. However, there is no good evidence that stents prevent heart attacks in people who have chest pain during exercise. The ORBITA study showed that in patients with medically-treated heart pain and severe heart artery blockage, stents did not increase exercise time more than a placebo procedure.
Paul D. Thompson, M.D., an accomplished competitive international marathon runner as well as a respected cardiologist, has written an editorial on two studies that show how important regular vigorous exercise is to prolong lives and prevent heart attacks and strokes. The results of these studies should stimulate every able-bodied person to try to exercise for at least 30 minutes every day for as long as they can.
Today's aspirin is a manufactured copy of the salicylic acid from willow bark plus acytl chloride (acetylsalicylic acid). The bark of willow trees has been used medicinally for more than 5000 years. Doctors have known for more than 200 years that salicylates in plants can prevent clotting
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
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
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.
Thirty percent of all deaths in the world are due to heart disease. The authors of a new study, covering 3.8 billion people in 186 countries, believe that there would be a great reduction in heart attack deaths if people increased their intake of the healthful vegetable unsaturated fats,
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.
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.
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...
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.
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.
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
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...
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.
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...
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.
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.
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,...
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.
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...
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" .
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.
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
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...
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.
