What Do Blood Cholesterol Levels Mean?

Having a high (>100 mg/dL) bad LDL cholesterol or a low (<40) good HDL cholesterol has long been associated with increased risk for heart attacks. However, new studies show that you can form plaques and be at risk for a heart attack even if your bad LDL cholesterol is as low as 50.

Insulin Resistance Predicts Heart Attacks and Diabetes

An article written by two highly-respected physicians and an investigative reporter concludes that, "Emerging evidence shows that insulin resistance is the most important predictor of cardiovascular disease and type 2 diabetes" .

Both Low and High HDL Can Predict Harm

Having high blood levels of the bad LDL cholesterol predicts increased risk for heart attacks, but contrary to what we thought in the past, having high levels of "good" HDL cholesterol does not necessarily predict protection from heart disease. A recent report from the Copenhagen General Population Study shows that having either low or high levels of HDL cholesterol also predicts increased risk for infections such as gastroenteritis and bacterial pneumonia.

Blood Pressure Guidelines

The American Heart Association, the American College of Cardiology and nine other heart health groups now agree that you have high blood pressure if your blood pressure is above 130/80, not 140/90 as the previous guidelines recommended.

HDL Cholesterol: a New Understanding

For many years HDL cholesterol has been called "good" because it carries plaque-forming particles from your arteries and bloodstream back to your liver where they can be removed from your body. An exciting new study shows that regular HDL cholesterol may not be very effective in doing this, but another form called Nascent HDL carries these protein-fats much more quickly to your liver to be removed from your circulation.

Questions About Stents

A recent study suggests that stents placed in arteries leading to the heart have not been shown to cure chest pain (Lancet, Nov 2, 2017). Placing stents in people who have heart pain from narrowed arteries and giving them medication is not more effective in relieving pain than just giving them medication and no stents. Stents do help to prevent the heart muscle from dying when put in place within the first few hours after the start of a heart attack.

Exercise Helps People with Heart Disease

A recent study shows that stable angina patients who exercise are less likely to die from heart attacks. Stable angina means that you may or may not have chest discomfort or pain at rest, but pain occurs or worsens when you exert yourself.

Deceptive Headlines about Exercise and Heart Attacks

"You Can Exercise Yourself to Death, Says New Study" was the headline in The New York Post on October 17, 2017. Headlines like that are likely to discourage people from exercising and thus to shorten their lives.

Breakfast Skippers Have More Plaques

A new study surveyed more than 4,000 adults ages 40 to 54 about their breakfast habits and then checked them for heart attack risk factors. The researchers found that people who eat a large percentage of their total daily calories for breakfast have the fewest heart attack risk factors, while those who skip breakfast are more likely to have plaques in their arteries and other heart attack risk factors.

Plaques are Reversible

Most heart attacks are caused by lifestyle factors, not by genes, and the prevention of heart attacks depends far more on what you do now than what you did earlier in your life. It is an incredible tragedy that many physicians prescribe statin drugs to prevent heart attacks without also explaining the importance of lifestyle changes.

Blocking Inflammation to Prevent Heart Attacks

In the biggest advance in knowledge about the prevention of heart attacks since the discovery of statins, researchers at Harvard Medical School have shown that blocking inflammation helps to prevent heart attacks and cancers.

Heart Attack Prevention

The majority of heart attacks are caused by unhealthful lifestyles, not by genetic defects. Statins remain the major choice of preventative drug, but everyone should realize that many studies show that lifestyle changes are probably more effective than statins in preventing heart attacks.

Exercisers Have More Stable Plaques

Two recent breakthrough studies give the best explanation yet of how exercise helps to prevent heart attacks. Competitive older endurance athletes may have more plaques in their arteries than non-exercisers, but they have the type of plaques that are far less likely to break off and cause heart attacks.

Blood Pressure During and After Exercise

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.

Red Yeast Rice Pills

People who take red yeast rice pills to lower their cholesterol levels may not be getting their expected protection against suffering a heart attack. North Americans spend an estimated 40 million dollars a year on these pills.

Alcohol and Heart Attacks

Moderate drinking does not appear to prevent heart attacks. An analysis of 45 studies of relationships between heart attacks and alcohol consumption reports that the studies that associated moderate drinking with reduced heart attack rates are flawed.

NSAIDs May Increase Heart Attack Risk

Millions of people take over-the-counter NSAID pain medicines when they have a headache, fever, chills, joint pain or various other aches and pains. A new study shows that NSAIDs are associated with increased risk for heart attacks.

Heart-Healthy Diet

Several recent articles provide new data on which foods are associated with both your health and your longevity., including a major statistical analysis of the association between diet quality and rates of death from the cardiometabolic diseases (heart disease, strokes and type II diabetes).

Irregular Heartbeats in Older Athletes and Exercisers

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.

Aspirin’s Benefits from Plants

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

Statins, Low Vitamin D and Muscle Pain

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...

How Soluble Fiber Helps to Prevent Heart Attacks

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

Muscle Pain from Statins

Up to 75 percent of people who are prescribed statins stop taking them within two years, and 65 percent of those patients reported that they stopped because of side effects, primarily muscle pain.

Irregular Heartbeats in Lifelong Exercisers

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

Belly Fat Predicts a Heart Attack

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.

Plaques in Arteries are Reversible

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.

Angina: Chest Pain During Exercise

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

Reduce Heart Attack Risk with Vegetable Oils

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,

Triglyceride/HDL Ratio Predicts Heart Attacks, Diabetes

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’s Questionable Results

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
