The American Heart Association (AHA) reports that a high waist circumference among individuals with normal weight appears to be a more reliable predictor of risk for heart attacks than just being overweight. The AHA recommends using the ratio of waist circumference to body height or the waist-to-hip ratio to warn about increased heart attack risk.
People who had higher blood levels of omega-3 fatty acids at the time of a heart attack were far less likely to die or to have repeat heart attacks within three years, compared to those who had lower levels. The sources of omega-3s in the 944 heart attack patients in this study included both fish and plants.
A study of 7063 people, average age 58.9 years, found that those who had high blood pressure had significantly lower memory and recognition test scores than the people with normal blood pressure. In four years of follow-up, they found that better control of high blood pressure during the study period helped to reduce the loss of mental function.
You can’t depend completely on blood pressure measurements done only in a doctor’s office because being active, having “white coat syndrome,” (feeling nervous or stressed), or an improper hurried measurement can raise blood pressure considerably. In one study, systolic blood pressure was 7.3 mm Hg higher in a doctor’s office than when measured more precisely in a research setting.
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.
A final report on the official outcomes of the ISCHEMIA Studies was recently published. It suggests that most people with clogged arteries do as well with medication and lifestyle changes as they do after undergoing invasive procedures to reopen their blood vessels such as stents, balloon angioplasty or bypass surgery
People who are at high risk for suffering a heart attack because they have a genetic factor that causes high LDL (bad) cholesterol should be treated with severe restriction of added sugars and all refined carbohydrates. The same advice should be given to people who are at increased risk for heart attacks for any reason.
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.
Two to three million years ago, our pre-human ancestors had a single genetic mutation in their CMAH gene that protected them from a deadly form of malaria but set them up for risk for heart attacks that increases when they eat a lot of meat from any kind of mammal (PNAS, July 22, 2019)....
A study of more than 100,000 healthy Chinese citizens followed for nine years showed that having very low levels of LDL cholesterol (<70 mg/dl) is associated with increased risk for bleeding into the brain, and the lower the LDL, the greater the risk (Neurology, July 2, 2019). Normal blood levels of LDL cholesterol are...
Atrial fibrillation is the most common irregular heartbeat. It occurs in 1.5 to 2 percent of the general population and risk increases with age. It affects 10 percent of 75-year-olds and 20 percent of those over 85, because aging increases the risk factors for atrial fibrillation such as blocked arteries, high blood pressure or...
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.
