Monitoring your heart rhythm with a smartphone: A good call?

An app that detects an irregular heart rhythm could be reassuring for people worried about afib.

Just over two years ago, the FDA approved the AliveCor Heart Monitor, which consists of a smartphone app plus a phone case with special sensors on the back. Touching the sensors with your fingers allows you to see a simple version of your heart's electrical activity on the phone screen. In the latest version, called Kardia, the sensors just need to be near (not necessarily on) your phone. The readout reveals if your heart rhythm looks normal or if you appear to have atrial fibrillation (afib)—a rapid, irregular heart rhythm that raises the risk of stroke.

Currently, several new smartphone apps to alert you about possible afib using just the phone itself—no special case required—are under development. Recent research suggests they're about as accurate as the Kardia system, although they haven't yet been cleared by the FDA and aren't on the market. If and when they are, could these apps help improve afib screening?

Fatty liver disease and your heart

About one in three adults has nonalcoholic fatty liver disease, an often-silent condition closely linked to heart disease.

The largest organ inside your body, your liver performs hundreds of vital functions. It converts food into fuel, processes cholesterol, clears harmful toxins from the blood, and makes proteins that help your blood clot, to name a few. But an alarming number of Americans have a potentially dangerous accumulation of fat inside their livers. Known as nonalcoholic fatty liver disease (NAFLD), this condition is a leading cause of chronic liver disease in the United States—and an increasingly recognized contributor to heart disease.

"NAFLD increases the risk of heart disease independent of other traditional risk factors such as high blood pressure and cholesterol," says Dr. Kathleen Corey, director of the Fatty Liver Disease Clinic at Massachusetts General Hospital. Among people with NAFLD, heart disease is the top killer, accounting for more than 25% of deaths.

What can be done about droopy eyelids?

Droopy eyelids, known as ptosis, are often a normal occurrence of aging although some neurologic conditions also can cause the condition. Ptosis is not a serious problem unless it interferes with your vision. If this happens, or if your droopy eyelids are bothersome, you can opt for cosmetic surgery to repair your eyelids.

Is a heartburn drug hurting your health?

Long-term risks are associated with proton-pump inhibitors, but there are other options for treating acid reflux.

Proton-pump inhibitors (PPIs), which reduce the amount of acid produced in the stomach, are so effective at treating heartburn and ulcers that they've been among the world's top-selling drugs for 25 years. Initially available only by prescription, PPIs, which include omeprazole (Prilosec), lansoprazole (Prevacid), and esomeprazole (Nexium), have been sold over the counter for several years. However, now that millions of people are taking PPIs, the drugs have been linked to an increasing number of health risks, such as fractures, kidney problems, vitamin B12 deficiency, low magnesium, and—most recently—dementia and heart attack.

"These studies—especially those suggesting a relationship to dementia and heart attack—are concerning," says Dr. Jacqueline Wolf, a gastroenterologist and associate professor of medicine at Harvard Medical School and author of A Woman's Guide to a Healthy Stomach: Taking Control of Your Digestive Health.

A warning about heartburn medications that contain aspirin

The FDA is warning that over-the-counter antacids with aspirin in them can cause stomach bleeding in rare cases. 

Gum disease may signal warning for pancreatic cancer

Research has found that people with high levels of the oral bacteria Porphyromonas gingivalis had a 59% greater risk of developing pancreatic cancer. It is too early to say whether this specific bacterium directly contributes to the disease. However, one theory is that since inflammation is related to cancer, the bacteria could cause inflammation in the pancreas. Another possibility is the bacteria are simply a marker for cancer-causing inflammation. 

Unveiling post-traumatic stress disorder

Often considered an ailment of only military veterans, this condition also can affect many older men.

Mention post-traumatic stress disorder (PTSD), and most people immediately think of military veterans. While this group is highly susceptible to PTSD, research has shown that older adults, specifically men, are also vulnerable.

PTSD is a potentially debilitating condition that can occur in people who have experienced a natural disaster, war, terrorism, serious accident, violent personal assault, or similar traumatic event.

Why you should always have aspirin on hand

This old standby may not be your first choice for pain relief, but it still has an important role in disease prevention and first aid.

We have a lot to thank aspirin for. It's cheap and plentiful. It does a good job of relieving pain and bringing down fevers. It has also been shown to reduce the risk of heart attack, stroke, and colon cancer. It can even stop heart attacks and strokes in their tracks. In fact, if you're in your 50s or 60s, you may want to think about taking a low-dose aspirin every day.

After evaluating the results of scores of studies, in April 2016 the U.S. Preventive Services Task Force (USPSTF) recommended that women and men ages 50 through 69 who have a 10% risk of a heart attack or stroke in the next 10 years take 81 milligrams (mg) of aspirin daily. Under the previous recommendations—which, were different for men and women—daily low-dose aspirin was advised for women ages 60 through 79 who were at increased risk for cardiovascular events. The recommendation was revised to reflect a new method of calculating the risk of heart attack and stroke and of increased risk of bleeding in older people.

Attack of the gallstones

They affect more women, but men still are at risk.

Most people never think about gallstones—that is until they experience the severe, gut-piercing pain of a gallstone attack. "These often strike after eating, especially a high-fat or high-cholesterol meal, and can last about 30 minutes to two or more hours," says Dr. William Brugge, past director of gastrointestinal endoscopy at Harvard-affiliated Massachusetts General Hospital.

The attacks often begin in the upper-right side of the abdomen and may spread to the back, between the shoulder blades, and under the right shoulder. Nausea or vomiting may also occur.
