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
Medical researchers agree that exercising into old age helps to prevent heart attacks, strokes and cancers and prolongs lives, but a recent report shows that sometimes competing in endurance sports may cause atrial fibrillation that can be fatal.
Athletes in sports requiring great strength who eat a very-high protein diet increase their risk for dying at a young age of heart attacks, even though protein loading does not grow larger muscles.
People who have had heart attacks are also at high risk for certain cancers because the same lifestyle factors increase risk for both and appear to be far more important than genetics in determining your likelihood to suffer both conditions.
Up to 20 percent of people who take statin drugs to lower cholesterol suffer from muscle aches, particularly when they try to exercise. A systematic review found eight studies that showed that Co-enzyme Q10 (CoQ10) does not reduce statin-induced muscle pain, compared to placebo.
Having high blood levels of the bad LDL cholesterol (>100 mg/dL) is associated with increased risk for heart attacks and premature death, and is the single most important predictor of forming plaques in your arteries. Many experts recommend lowering elevated LDL levels to 70 mg/dL in people who are at increased risk for heart attacks.
Many studies show that eating meat every day is associated with increased risk for heart disease, but until now we have had little data about the effects of eating meat less often than that. A new study followed 29,682 participants, average age 53.7, for 30 years and found that eating two servings per week of mammal meat or processed meat was associated with a seven percent increased risk of heart disease.
A recent Danish study followed 54,903 healthy men and women, 50-64 years old, for 16 years. Those who ate primarily fermented dairy products such as cheese and yogurt were significantly less likely to suffer heart attacks than those who drank milk.
As you age, you can expect to suffer from sarcopenia (loss of muscle size and strength). The smaller the muscles in the arms, legs and trunk, the smaller and weaker the upper and lower chambers of their heart. Having a smaller and weaker heart muscle puts a person closer to heart failure.
A huge study from Korea confirms that people with Metabolic Syndrome are at increased risk for heart attacks, and that when they correct some or all of the components of Metabolic Syndrome, their risk for a heart attack goes down dramatically.
Since heart attacks are usually caused by plaques breaking off from the inner linings of arteries leading to the heart, doctors use a test called Coronary Artery Calcium Score (CAC) to predict which people have the largest plaques and therefore are at high risk for suffering heart attacks that cause one out of four deaths in North America.
Stents and Bypass Surgery Not More Effective than Lifestyle Changes and Medication for Stable Heart Disease
The $100 million ISCHEMIA Trial showed that after four years, surgical treatments (stents or coronary artery bypass surgery) were not more effective than lifestyle changes and medication in preventing heart attacks deaths in patients with stable heart disease.
An analysis of 7,743 people suffering from osteoarthritis found that those who took NSAIDs (non-steroidal anti inflammatory drugs) were at 41 percent increased risk for suffering heart attacks, heart failure and strokes, compared to arthritis patients who did not take NSAIDs.
Heart attacks and strokes cause 50 percent of the deaths in North America today, yet many people are not adopting the lifestyle changes needed to prevent the factors that cause them: inflammation and clotting. A new study from the University of Michigan shows how important inflammation is as a cause of heart attacks and strokes.
The CARDIA Study shows that having certain types of bacteria in your colon is associated with having high blood pressure, and that you can lower blood pressure by improving the proportion of healthful to unhealthful bacteria in your colon. Lifestyle changes may be more important than drugs in treating high blood pressure.
A strong new study shows that with aging, there is an increase in the types of harmful colon bacteria that produce amines, specifically TMAO (trimethylamine oxide), that damage arteries to increase risk for heart attacks, strokes and cell damage throughout your body.
A study of 21,758 men, average age 51.7 years, followed for an average 10.4 years, showed that men who exercised the most have more plaques in their arteries, but do not suffer more heart attacks or deaths than those with less heart artery calcification.
Aspirin has been shown to help prevent a second heart attack in people who have already had a heart attack. However, aspirin also causes bleeding that can kill a person, so researchers wanted to find out if the heart-attack-preventing effects of aspirin would be offset by the complications of bleeding that aspirin can cause.
Some recent research articles seem to warn people not to exercise too long or too hard, but the overwhelming scientific and epidemiological evidence is that vigorous exercise strengthens a healthy heart and helps to prevent heart disease. Elite endurance athletes who exercise long hours each day outlive their less-active peers, as do Tour de France cyclists. However, three studies raise the possibility that extreme exercise such as running a marathon could possibly increase risk for heart problems, particularly in people who are not adequately trained for their events.
High blood pressure (greater than 130/90 before you go to bed at night) markedly increases risk for heart attacks, strokes, heart failure, and premature death. Almost 50 percent of North American adults have high blood pressure, and it causes more than 80,000 U.S. deaths each year. A plant-based diet can help to prevent and treat high blood pressure because it contains lots of soluble fiber.
Being overweight is associated with having larger plaques in the arteries leading to the heart and a marked increase and progression of these arterial plaques that cause heart attacks, even if a person does not have the risk factors that predict increased risk for diabetes and heart attacks.
On November 10, 2018, heart specialists presented the latest recommendations for preventing heart attacks from the American College of Cardiology and the American Heart Association: Treat all of their patients with recommendations for heart-attack-preventing lifestyle changes, and Treat all patients with significant heart attack risk factors with medications that lower blood levels of the bad LDL cholesterol.
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.
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.
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.
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.
The evidence is overwhelming that statin drugs do help to lower cholesterol and to reduce risk for heart attacks. However, a new study confirms that statins interfere with the ability to exercise and to compete in sports, even in patients who report no symptoms.
Studies this month show that neither taking omega-3 polyunsaturated fatty acids (PUFAs) in fish oil pills nor eating fish reduce the risk for heart attacks, September 16, 2016). A review of studies in the world's scientific literature agrees that taking fish oil pills does not prevent heart attacks.
