Controlling Your Blood Pressure Archive

About 66% of adults over age 70 still take antihypertensive medication even though they now have low pressures, says a study from the University of Kent in the United Kingdom. Researchers say this exposes adults to medication side effects like dizziness and falls. 

Home sleep tests to diagnose obstructive sleep apnea (OSA) may reliably detect the disorder even if a sleep specialist is not involved. Marked by loud snoring and breathing lapses during sleep, OSA can increase the risk of cardiovascular disease.

An electronic home blood pressure monitor is a better option than a store-based machine for measuring blood pressure between doctor office visits. Arm cuff machines are more accurate than wrist cuff models. 

Your resting heart rate can be an instant measure of your present and future health.

One of the easiest ways to gauge your health can be done in 30 seconds with two fingers. Measuring your resting heart rate (RHR), the number of heartbeats per minute while at rest, provides a real-time snapshot of your heart muscle function.

It is easy to do. Place your index and middle finger on your wrist just below the thumb, or on your neck to one side of your throat, so you can feel your pulse. Use a watch to count the number of beats for 30 seconds and double it to get your beats per minute. Repeat a few times to get an accurate reading. A normal RHR for most adults ranges from 60 to 100 beats per minute.

When older people start taking a new blood pressure drug or change the dose of their current drug, they may be more prone to a serious fall during the following two weeks. But this increased fall risk doesn’t seem to persist over the long term. 

A high blood pressure diagnosis can come as a shock due to a lack of symptoms, but the condition is manageable. Dr. Naomi Fisher explains what to do after you are diagnosed.

Take an active role by checking your blood pressure with a home monitor.

Most appointments with a health care provider begin with a gentle squeeze—the sensation of a blood pressure cuff inflating around your upper arm. But that single blood pressure reading offers only a glimpse of the health of your cardiovascular system.

"When you have your blood pressure checked in the doctor's office, you're in an artificial environment that is not reflective of the vast majority of the time when your blood pressure is going through its daily excursions," says cardiologist Dr. Elliott Antman, professor of medicine at Harvard Medical School. Throughout the course of a day, the average person's systolic b-lood pressure (the first number in the reading) may fluctuate considerably.

Your primary care provider should help you control risks for heart disease and refer you to a cardiologist if needed.

Any primary care provider you see—a doctor, nurse practitioner, or physician's assistant—should offer detailed advice on how to lessen your odds of cardiovascular disease, which is responsible for one in three deaths in the United States. However, some people need more specialized care for their hearts.

"I see or hear from a lot of people who have very common problems, like high cholesterol and high blood pressure, who think they need to see a cardiologist," says Dr. Patrick O'Gara, a cardiologist at Harvard-affiliated Brigham and Women's Hospital. For many people, a primary care physician can effectively manage those problems. But if you have specific concerns, talk to your doctor about whether more specialized care might be beneficial, says Dr. O'Gara.

The longstanding "More Matters" campaign urges Americans to eat more fruits and vegetables (see www.fruitsandveggiesmorematters.org). Evidence to support this healthy habit keeps piling up, with the latest from a study that pooled dietary data from three large, long-term studies that followed more than 187,000 people for an average of over 20 years.

The researchers found that people who ate more whole fruits—especially apples, pears, grapes, and raisins—were less likely to develop high blood pressure than those who rarely ate those foods. As for vegetables, broccoli and carrots appeared to be the best choices for staving off high blood pressure. Fruits and vegetables provide minerals such as potassium and substances called flavonoids, both of which are linked to lower blood pressure. The study was published online in the Dec. 7, 2015, issue of Hypertension.

The strength of your hands may hold clues to the health of your heart. A study in the December 2015 American Journal of Preventive Medicine found that people with stronger handgrips had more favorable findings on measures of their cardiovascular health than those with weaker grips.

The study included more than 4,200 adults ages 20 and older who were part of a nationwide health study. Researchers used a device called a dynamometer to measure each participant's hand strength, adjusting the readings based on body mass index. They found that higher handgrip strength was associated with lower blood pressure, lower triglycerides (a type of fat in the blood), lower blood sugar, and higher HDL (good) cholesterol.
