Heart checks at home pushed

Everyone with high blood pressure - some 72 million Americans - should own a home monitor and do regular pressure checks, the American Heart Association and other groups urged yesterday in an unprecedented endorsement of a medical device for consumers.

High blood pressure is a leading cause of heart attacks, strokes and death. Having it checked a few times a year in a doctor’s office or at the drugstore is not enough to keep tabs on it, and regular home monitoring is more accurate, the new advice says.

Closer checks would let doctors fine-tune the many medicines used to control high blood pressure, just as diabetics adjust their insulin levels by regularly monitoring blood sugar. Only a third of people with high blood pressure have it under control.

“We need new approaches. Our current approach is simply not working,” said Dr. David Goff, a preventive medicine specialist at Wake Forest University and a member of the panel that wrote the advice.

Outside experts strongly agree. But some say the case would be more compelling if those pushing the monitors had no industry ties. For example, a leading device maker pays more than $300,000 a year to co-sponsor the heart association’s blood pressure Web site, www.americanheart.org. The company played no role in the new advice, the association said.

“This is not as clean a recommendation as it could be” because of the industry ties, said Dr. Sidney Wolfe of the consumer group Public Citizen.

They cost $50 to $100 on the Internet and at pharmacies. Insurance usually doesn’t pay, though the heart groups say it should.

The heart association, the American Society of Hypertension and the Preventive Cardiovascular Nurses Association all urged home monitoring in a statement published online yesterday in the journal Hypertension, hyper.ahajournals.org. Hypertension is the medical word for high blood pressure.

The condition occurs when blood pulses too forcefully through vessels, which can damage the heart, kidneys and other organs. It’s more common as people age, and leads to about 7 million deaths in the U.S. each year.

Readings of 140 over 90 are considered high at the doctor’s office; 135 over 85 if taken at home. Pressure often goes up with the “white coat” effect, nervousness when seeing a doctor. Readings also vary throughout the day.

“So often we rely on a single measurement in the office and it’s so arbitrary,” said Dr. Allen Taylor of Walter Reed Army Medical Center, a prominent researcher not involved in the new advice.

Many types of medicines can help control high blood pressure, and often more than one is needed. Finding the right dose or combo is tricky.

Home monitors can help, by giving a better picture of pressure variations and the response to a drug. Sometimes less medication is needed, because doctors discover that pressure was artificially high when someone was in the office, Dr. Goff said. That spares people the cost and side effects of unnecessary treatment.

Often, though, the opposite is true - people need more or different drugs.
