Answers to the top questions about cannabis extract

Updated April 1, 2019

Sales of cannabidiol-infused products are expected to top $2 billion by 2021. But is CBD right for you?

Cannabidiol (CBD) is touted as a natural wonder that can help treat symptoms of everything from anxiety to arthritis pain. The plant extract comes from two varieties of cannabis — hemp and marijuana — and is available in creams, tinctures, oils, patches, gummy bears, capsules, and more. You can even add CBD to a latte if you walk into a coffee shop in some cities.

But is CBD safe for older adults? There haven't been a lot of large studies of CBD's safety, but more traditional medicines for pain and anxiety are not free of adverse effects, either. "I think CBD is likely safer than many other treatments people use for pain, insomnia, or anxiety," says Dr. Peter Grinspoon, a primary care physician with Harvard-affiliated Massachusetts General Hospital. Other physicians don't think we know enough about the safety profile of CBD to be sure.

Muscle aches from statins: Real, but sometimes imagined?

Updated April 1, 2019

The "nocebo effect" may explain why some people believe they can't tolerate statins.

For more than 20 years, cholesterol-lowering statin drugs have been a mainstay for preventing and treating heart disease. But up to half of people prescribed these drugs are no longer taking them within a year or two. The reasons vary, but some people experience what they believe to be statin-related side effects — most often muscle pain. Others avoid statins altogether because of worries over side effects.

"Far too any people think they cannot tolerate statins when they actually can," explains Dr. Jorge Plutzky, director of preventive cardiology at Harvard-affiliated Brigham and Women's Hospital. To be clear, muscle problems are a known side effect of statins. However, serious muscle-related complications are extremely rare (see "What is rhabdomyolysis?"). And when people experience the more common — but less worrisome — muscle-related symptoms, those issues usually resolve with a lower statin dose or a change to a different statin, Dr. Plutzky says.

What happens if my stent stops working?

Updated April 1, 2019

Ask the doctor

Q. I just got a stent placed in my heart artery and feel great again. If it develops problems, can it be treated?

A. Stents, the tiny wire-mesh tubes used to prop open blocked arteries, are useful for treating heart attacks and chest pain that occurs with physical activity. They're placed during a coronary angioplasty and stenting procedure, which usually involves snaking a thin tube (catheter) through a vessel in the upper thigh or the wrist up to the heart. After more than two decades of use, today's stents are safer and more effective that the original versions. Problems can still arise, but they are uncommon and treatable.

Heart rhythm monitoring with a smartwatch

Updated April 1, 2019

These wrist-worn devices are better than ever at gathering data. But it's still too early to use them to screen for atrial fibrillation.

The original wristband monitors were pretty basic: they tracked your movement and tallied your daily steps. But before long, these digital devices could also estimate your heart rate, thanks to a sensor that measures changes in blood flow through your skin. Now, there are smartwatches with special sensors that can record a tracing of your heart's electrical signature (electrocardiogram or ECG) and alert you if it detects an irregular rhythm.

Last fall, the FDA granted Apple approval for the ECG sensor and an app that includes an algorithm to detect atrial fibrillation, or afib, the most common heart rhythm disorder (see "What is atrial fibrillation?"). While the Apple Watch Series 4 is the first of its kind to offer this feature, other companies have similar technologies in the works.

Nothing to sneeze at

Updated April 1, 2019

Here's how to prepare for the coming allergy season.

Spring is in the air, and so are millions of pollen particles, the tiny grains that fertilize plants. Seasonal allergies — also known as hay fever — can affect almost anyone and at any time in life. Although most people begin to experience allergies in childhood or early adulthood, sometimes the symptoms become more problematic later in life, especially if their living environment changes.

"Even if you have never suffered from allergies — or used to when you were much younger but not anymore — there is a good chance you will become more sensitive to pollen as you reach your 60s and 70s, although it's not clear why," says Dr. Mariana Castells, of the Department of Allergy, Rheumatology, and Immunology at Harvard-affiliated Brigham and Women's Hospital.

The combo of Mediterranean diet and statins can protect against a fatal second heart attack

Updated April 1, 2019

In the journals

People who have had a heart attack or a stroke are routinely prescribed a statin to reduce the risk of a repeat event. But by also following a Mediterranean-style diet, they can improve their chance of living longer, suggests a study in the Feb. 1, 2019, issue of the International Journal of Cardiology.

The study looked at 1,180 people, average age 68, who had at least one previous heart attack or stroke, and recorded their statin use and diet intake at the study's beginning. The researchers identified the people who faithfully followed a Mediterranean-style diet. A Mediterranean-style diet involves consuming medium to high amounts of whole fruits and vegetables, whole grains, legumes and nuts, olive oil, and poultry and fish, with limited amounts of red meat, alcohol, and dairy.

Feeling the burn? Antacids can provide some relief

Updated April 1, 2019

But these remedies aren't the best choice if you have frequent heartburn.

You feel the familiar sensation in your chest: heartburn. Again, you find yourself reaching for the bottle of antacids in the medicine cabinet. It's something you've done a few times a week for the past six months. Is it okay to keep popping over-the-counter acid reducers, or is it time to see a doctor?

We asked two experts, Dr. Jennifer Nayor and Dr. Molly Linn Perencevich, both instructors in medicine at Harvard Medical School, for their thoughts on heartburn, including when it's okay to use over-the-counter antacids and when you should seek other treatments. Below are their responses.
