Eating less food—and less often—is better for our metabolism. By Holly Strawbridge Many of us were raised to believe that three square meals a day are necessary to be healthy. But recent discoveries about how our body produces and uses insulin suggest this might not be the best eating plan. The new thinking is that […]
New app helps individuals with diabetes understand how weight-loss surgery could improve their health. By Holly Strawbridge There is solid evidence showing that weight-loss surgery also known as metabolic or bariatric surgery can improve cardiovascular risk in patients with type 2 diabetes and obesity. However, few eligible patients only 1% ever have the surgery. Failure […]
If you have heart or kidney disease, you may need to take extra measures to maintain normal levels of this important mineral. By Holly Strawbridge Do you remember what you learned about potassium in science class? You were taught it’s a soft metal, a mineral and one of the most abundant elements on earth. But […]
Recent research contradicts standard advice that eating meat contributes to heart disease. Esteemed cardiologists would like to set the record straight. By Holly Strawbridge In October 2019, the medical world was shocked by five articles in the Annals of Internal Medicine that contradicted advice physicians have been giving for years: Cut back on eating meat, […]
If you are at low risk for cardiovascular disease (CVD), but take a daily low-dose aspirin anyway in hopes of preventing a heart attack, you should know that the practice is not likely to be helpful and may be harmful.
Avoiding sweets during the year is no easy task, but in December its almost impossible. So many holiday memories are inextricably linked to sweet treats: baking Christmas cookies or spinning the dreidel for chocolate gelt, for example. And how festive would a holiday party be without a table full of desserts?
Research Reveals Which Diet Is Best for the HeartWhat type of diet should you follow to lower your risk of heart disease? Results of the OmniHeart trial, published Aug. 2 in the International Journal of Cardiology, added to a growing body of evidence from other studies that eating a variety of healthy foods is more important than the specific diet you follow. Researchers randomized 164 adults with elevated blood pressure to three diets: the DASH diet, which contains 51% healthy carbohydrates (carbs), a high-protein diet that limits carbs and a diet that replaced a proportion of carbs with healthy unsaturated fats.
Although the effects of ASA are not fully understood, they may be a possible risk factor for an unexplained ("cryptogenic") stroke, since the occurrence is higher in patients undergoing echo in this setting. In these cases, the ASA is usually large and/or hyper mobile and is associated with a large amount of blood being shunted between the atria due to a PFO or septal defect. Identifying these abnormalities in a stroke patient does not necessarily prove a causal relationship, since other stroke causes may be present.
A key differentiator is the intensity of pain.In the movies, heart-attack victims often clutch their chest and grimace in pain before collapsing. But it is unusual for a heart attack to produce intense pain. Heart-attack pain is generally described as an unrelenting sensation of pressure, like an elephant sitting on your chest.
Yet about 30 percent of cardiac catheterizations performed in patients with stable coronary artery disease show evidence of a chronic total occlusion (CTO). In this situation, blood flow through a coronary artery has been totally blocked for more than three months. Studies have shown that when more than 10 percent of the heart muscle is affected by a CTO, the patient has a significantly higher risk of death or major adverse cardiac event. These patients often suffer from angina that is severe enough to impact their quality of life.
Many times, bradycardia is caused by a problem with the heart's sinoatrial (SA) node. This so-called "natural pacemaker" is a cluster of cells in the right atrium that sends electrical signals to help control the heartbeat. An SA that does not work properly can cause the heart rate to slow down, speed up or become inconsistent. Sometimes, a pacemaker is required. A pacemaker that detects bradycardia sends a signal to the heart that restores a healthy rate.
A rare, but serious, problem can occur when a DVT blood clot breaks off and is carried into a heart that has a hole between its upper chambers (patent foramen ovale, or PFO). If the clot passes from the right side of the heart into the left and is pumped into the arteries supplying the brain, it can cause a stroke.
