The US Preventive Services Task Force (USPSTF) has advised against people aged 60 and older taking aspirin for primary heart attack prevention because of their increased risk for bleeding into the brain or gastrointestinal tract.
Having blood triglyceride levels above 150 mg/dL (1.7 mmol/L) puts you at increased risk for a heart attack, stroke, or heart valve disease, even if your blood cholesterol levels are normal (Eur Heart J, Dec 2021;42(47):4791-4806). About 10 percent of North Americans suffer from high triglyceride levels. High triglycerides are often found in people who are diabetic, obese or alcoholic.
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.
Very aggressive control of high blood pressure helps to prevent heart attacks, strokes and premature death far more effectively than less stringent control. You cannot cure high blood pressure with drugs, you can only control it as long as you continue to take the drugs. Most of the time, your blood pressure cannot be controlled with just one drug and most people end up with three or more drugs to treat their high blood pressure.
A very important new study of 27,599 adults, average age 47-50, showed that almost 15 percent of North American adults and almost 19 percent of those with high blood pressure take medications that can raise blood pressure. The blood-pressure-raising medicines taken most frequently were antidepressants, NSAIDs, steroids, and estrogens.
A review of six major studies that measured salt intake by the amount of salt in the urine found that a high salt intake is associated with significantly increased risk for suffering heart attacks and strokes. This review is extremely dependable because it measured salt intake directly by how much salt and potassium was secreted in a person’s urine each day, and did not depend on a patient's memory.
If you have high blood pressure in the winter, you are at increased risk for a heart attack, even if your blood pressure is normal in the summertime. Blood pressure is often higher in winter and lower in summer, and heart attacks are significantly more common in the winter than in the summer
Daily aspirin can help to prevent heart attacks, but the United States Preventive Services Task Force now recommends that: adults 60 years and older should not take aspirin to help prevent a first heart attack, and those 40-59 years old who are at high risk for heart disease should take aspirin only on their doctor’s recommendation
Heart attacks are not caused by plaques making arteries too narrow. They are caused by plaques suddenly breaking off from the inner lining of a heart artery, followed by bleeding, and then a clot forms that completely blocks all blood flow to a part of the heart muscle.
Extensive recent research shows that high blood pressure is associated with having specific harmful bacteria in your colon, and that reducing harmful colon bacteria and increasing healthful ones can help to control high blood pressure. You can do this primarily by eating an anti-inflammatory diet, as well as by exercising regularly, losing excess weight, and avoiding smoke and alcohol.
High blood pressure affects 108 million adults, increasing risk for heart attacks, the leading cause of death in the United States. A Harvard study of 412 adults found that a low-salt version of the DASH diet dramatically lowered both high blood pressure and markers of heart muscle damage in just four weeks
More than one hundred million North Americans have taken statin drugs that help to save lives by lowering cholesterol and preventing heart attacks. Ten to 20 percent of people who take statins have been reported to have suffered muscle pain, but a recent study from the UK claims to show that statins are no more likely than a placebo to cause muscle pain.
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.
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
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.
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 one report shows that sometimes competing in endurance sports may cause atrial fibrillation.
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.
