The MARC-2 study followed 291 older men for 6.3 years with a test called Coronary Artery Calcification (CAC), and found that the amount of calcium in the arteries leading to the heart increased most in men who exercised at the highest intensity, even more than those who exercised the most. The authors said this showed that intense exercise increases the amount of plaques in arteries, which may be true. However, they would then have to explain why intense exercisers are far less likely to suffer heart attacks than non-exercisers
Researchers analyzed data from 3865 adults and found that more than 50 percent said that they did not know that alcohol increases cancer risk. The people who incorrectly thought that alcohol doesn’t cause cancer were the ones most likely also to think incorrectly that alcohol can help to prevent heart attacks.
Two blood tests that are done during routine physical exams can be used to predict whether you are at increased risk for diabetes and heart attacks. It’s called the triglyceride/HDL ratio, calculated by dividing your triglycerides number by your HDL number.
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.
A study of supplements that claim to lower cholesterol followed 199 patients at the Cleveland Clinic for 28 days. Participants were given either a supplement (fish oil pills, red yeast rice, cinnamon, garlic, turmeric or plant sterols), a statin drug (rosuvastatin, brand name Crestor, 5 mg/day) or a placebo.
To find out if they could predict how long an older person will continue to live, Duke University researchers used 1507 blood samples and lifestyle data from participants in the D-EPESE study that was conducted in New Haven, CT, in 1992. Participants were at least 71 years old when the study started, and the Duke researchers counted their years to death over the following 27 years
A respected group of researchers found that after a patient had a heart attack, taking one pill containing three heart drugs was more effective than taking similar prescribed drugs in separate pills during three years of follow-up (New Engl J of Med, August 26, 2022). The combined pill was more effective in preventing death from heart disease, another heart attack, strokes, or urgent surgery to replace heart blood vessels.
A study of 14,392 individuals with high blood pressure, followed for 5-10 years, found that those who adopted a healthful lifestyle along with taking medication had a much lower risk for suffering heart attacks and lived significantly longer than those who treated their high blood pressure just with drugs.
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.
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.
