Can a smart watch diagnose a heart attack?

ECG readings taken with a smart watch may be just as accurate as a traditional ECG done in a medical setting. But the notion of using a smart watch to diagnose a heart attack is still years away. One main reason: obtaining an ECG with a smart watch requires carefully holding the back of the watch on the wrist and at eight specific locations on the chest and abdomen. Quality control and regulatory issues are other important hurdles that need to be addressed. But experts believe improved smart watches with enhanced diagnostic ability may be on the market within a decade.

Taking fewer daily steps still offers protection from heart problems

People who take an average of 4,500 steps each day may have a lower risk of heart disease, stroke, and heart failure than those who take less than 2,000 steps per day.

How to recognize and respond to a "warning" stroke

A transient ischemic attack (TIA) can cause a range of unsettling symptoms, including slurred speech or arm weakness. The symptoms appear suddenly but usually last less than five minutes, which is why TIAs are often ignored or missed. However, two of every five people with a suspected TIA who get an appropriate brain imaging test find out that they actually had a stroke. Recognizing the symptoms and seeing emergency care right away is vital. The mnemonic BE-FAST (which stands for balance, eyes, face, arms, speech, and time) was designed to help people identify the symptoms of a TIA or stroke and to act quickly.

Sweet surrender: Added sugar linked to higher heart risk

Diets high in free sugar—which includes sugar added to processed foods and drinks as well as the sugar in syrups, fruit juice, and honey—are linked to an increased risk of cardiovascular disease.

Erectile dysfunction drugs linked to lower risk of heart problems

Otherwise healthy men treated with prescription drugs used to treat erectile dysfunction had a lower risk of heart attacks, strokes, or death from heart-related causes.

Short-term stroke symptoms still need emergency care

People who experience stroke symptoms that disappear in less than an hour, a phenomenon known as a transient ischemic attack, should seek immediate care to prevent a full-blown stroke.

The questions about fish oil supplements

Some research says taking a daily fish oil supplement can reduce the risk of heart attacks and strokes, while other studies say the evidence remains thin. While fish oil is the best source of omega-3 fatty acids (essential nutrients that the body cannot make on its own),  taking an over-the-counter fish oil supplement probably provides no extra heart benefit beyond a well-balanced diet that includes plenty of omega-3-rich fatty fish, nuts, and seeds.

The high cost of a poor diet

What people choose to eat has a big impact on their cardiovascular health. The dietary habits of the nation as a whole also have a major effect on the country's economic health. About 45% of the costs associated with heart disease, stroke, and diabetes is related to unhealthy diets. The dietary habits that appear to have the biggest effect are not eating enough nuts, seeds, and seafood omega-3 fatty acids. Among foods to avoid, sugary beverages and processed meats seem to contribute the most to higher costs. Each year, unhealthy diets cost the United States an average of about $300 per person in medical costs, which translates to $50 billion nationwide.

5 things to know about your morning cup of joe

A recent review found not only that coffee won't harm cardiovascular health or raise the risk of cancer, but it may actually have some health benefits. These include a lower risk of diabetes, and certain cancers, such as liver, and endometrial cancer. Many of these benefits may come from plant chemicals found in coffee.

Conquer your fear of dietary fat

For decades, high intake of fat was thought to cause weight gain, heart disease, and maybe even cancer. The solution? Go low-fat, which often meant consuming more carbs and more sugar. But nutritionists now suggest people actually need adequate amounts of "good" unsaturated fat, and less "bad" saturated fat, for optimal health. Following popular heart-healthy diets, like the Mediterranean and MIND diets, and making simple dietary changes can help people get adequate amounts of good fats.
