Most researchers believe that exercise helps to strengthen the heart and protect it from disease, but about twenty years ago, doctors noted that some men over 80 who competed in cross country ski races longer than 100 kilometers (60 miles) were at increased risk for an irregular heartbeat called atrial fibrillation.
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
Many people who take statin drugs complain of muscle pain and muscle damage. A new study associates this statin-induced muscle pain with low blood levels of vitamin D (Atherosclerosis, 11/22/2016). An eight–week randomized, double–blind crossover trial of a statin drug (simvastatin, 20 mg/day) on 120 patients who had previously complained of muscle pain from...
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
Many studies show that a lifetime of vigorous exercise makes the heart stronger and healthier and does not harm it. However, a few studies that got a lot of media attention suggested that chronic intense exercise can damage the heart to cause irregular heartbeats. Now a new study of elite lifetime endurance athletes has found no evidence of irregular heartbeats from damage to the right ventricular heart chamber
You are at high risk for a premature death if you can pinch more than three inches in your belly. Even people who are not overweight are at high risk for a heart attack and diabetes if they store most of their fat in the belly instead of in the buttocks, hips and thighs.
Almost anyone can get rid of plaques in their arteries, even if they have already had a heart attack or already have severe narrowing in the arteries leading to your heart. However, you have to do far more than just take drugs. The formation of plaques in arteries that eventually leads to heart attacks and strokes comes from chemical processes that start in the liver. Plaques can be reversed by changes in diet, exercise, weight, environmental exposures and medications.
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
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,
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.
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
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...
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,...
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.
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...
