If your doctor offers a way to monitor your chronic health condition via computer, consider giving it a try. A Harvard study that was published online April 23, 2018, by the Journal of General Internal Medicine found that people who had "virtual" office visits over the Internet were able to control their blood pressure just as well as people who had in-person follow-up office visits — and they used fewer health care services over all. Researchers compared the health outcomes of two groups. One group included about 900 people with high blood pressure who had in-office follow-up visits. The other group included about 900 people who had "virtual" follow-up visits, which meant they used a website to enter blood pressure readings, track their medications and side effects, and ask questions; their doctors determined whether to follow up by computer or phone or to schedule in an in-office visit. Over the course of six months, blood pressures improved for people in both groups. But people in the virtual care group averaged about one fewer office visit than people in the other group, and they had fewer emergency room visits and hospitalizations over all. The authors say the results support using virtual follow-up visits for other chronic diseases. Indeed, many health care providers already are doing so, including one group in the study — Massachusetts General Hospital, which uses virtual care to follow 65 different kinds of chronic disease.

About one in 10 people has eczema, a chronic inflammatory condition that leaves skin dry and itchy. People with more severe forms may experience a scaly rash or skin that cracks and oozes. These people may also be at greater risk for heart attack and stroke, according to a study in the May 23 issue of The BMJ.

For the study, researchers analyzed data from more than 385,000 adults with eczema, which was classified as mild, moderate, or severe. Each was matched with up to five people of similar age and sex who didn't have eczema.

Sharing readings from a home monitor with your physician may help you reach your blood pressure goal more quickly.

For treating certain health problems, finding the best drug or combination of drugs at the correct dose often requires some trial and error. High blood pressure is a good example. Because this common problem raises heart attack and stroke risk, the sooner you can get your blood pressure down to a healthy range (130/80 millimeters of mercury [mm Hg] or lower), the better. New research suggests that people could speed things up a bit by taking a more active role in the process (see "Tracking your blood pressure at home: Does it help?").

"The study showed that a period of home blood pressure monitoring — one week per month — was sufficient to guide people to better blood pressure control," says Dr. Paul Conlin, professor of medicine at Harvard Medical School and chief, Medical Service, at the VA Boston Healthcare System.

Peppers, which belong to the genus Capsicum, come in a variety of colors, shapes, sizes, and flavors. Bell peppers (available in green, yellow, orange, red, and even purple) make a nice addition to a salad or plate of crudités. Supermarkets carry bags of assorted mini bell peppers that are convenient both for snacking and using in recipes.

While sweet bell peppers are crunchy and mild, hot peppers — such as jalapeños, serranos, and habaneros — provide a tongue-tingling punch of heat. They contain varying amounts of the phytochemicals responsible for the spiciness in hot peppers.

Surprising new normal, healthy blood pressure for men by age 

What's good blood pressure for men by ages? As many as three-quarters of men over 65 have high blood pressure. Many end up taking medication to prevent heart attacks, heart failure, stroke, kidney failure, and erectile dysfunction.

For most people with blood pressure clearly in the red zone, getting their numbers below 140/90 millimeters of mercury (mm Hg) is a reasonable goal. However, in December 2013, a panel of experts convened by the National Institutes of Health (NIH) released a recommendation that people over age 60 with high blood pressure could settle for a goal of 150/90—not the more stringent standard of 140/90—and still get health benefits. The American Heart Association rejected the idea, and five of the 17 members on the NIH panel later publicly dissented with the majority opinion. The debate continues.

Although conventional wisdom suggests blood pressure rises gradually as people age, that isn't true for everyone, according to new research. However, a systolic blood pressure (the top number in a reading) that regularly goes above 120 to 125 mm Hg may signal impending high blood pressure, regardless of a person's age.

The study included data from 1,252 of the original participants of the Framingham Heart Study, who had their blood pressure measured roughly every two years between 1948 and 2005. Researchers then categorized the participants based on the age at which they received a diagnosis of high blood pressure (in their 40s, 50s, 60s, 70s, or never). They defined high blood pressure by the standard at the time: equal to or over 140/90 mm Hg.

Many people switch from stove to grill in the warmer months. But a new study links regular consumption of grilled meat to an elevated risk of high blood pressure. A study presented at the American Heart Association's 2018 Epidemiology and Prevention — Lifestyle and Cardiometabolic Health Scientific Sessions looked at more than 100,000 people in three different studies who ate at least two servings of beef, poultry, or fish each week.

They found that those who grilled their meat or broiled or roasted it at high temperatures more than 15 times each month had a 17% higher risk of high blood pressure than people who grilled, roasted, or broiled less than four times a month.

Is your workplace noisy? You may want to keep close tabs on your blood pressure and cholesterol. A CDC study published in the American Journal of Industrial Medicine found that high cholesterol and high blood pressure were more common among workers who toiled in noisy environments.

The study found that 25% of U.S. workers surveyed reported experiencing noise exposure at work. The noisiest industries included mining, construction, and manufacturing.

Roaring jets, rumbling trains, and revving automobiles may have a detrimental effect on your cardiovascular health.

According to a review article in the Feb. 13, 2018, Journal of the American College of Cardiology, many studies have observed a connection between transportation-related noise and a slightly higher risk of high blood pressure, coronary artery disease, stroke, and heart failure. The association persists even after adjustment for possible confounding factors, such as air pollution and socioeconomic status.
