Blood pressure measurements of 130/80 mm mercury (mm Hg) or higher at home can be used to diagnose hypertonia of white, black and latin american adults, according to new research in the American Heart Association Journal Hypertension .
“Until now, recommendations for high blood pressure diagnosis with home measurements have mainly come from Japanese and European studies,” said Wanpen Vongpatanasin, MD, study writer, professor of medicine and high blood pressure director at UT Southwestern Medical Center in Dallas. “We did not know if these recommendations were actually applicable to American adults.”
Researchers analyzed large multiethnic studies that compared home blood pressure to clinical measurements of primarily young and middle-aged adults in Dallas, Texas and Durham, North Carolina. At 420 participants in the North Carolina clinic, high blood pressure measurements (1
30/80) were confirmed with similar readings at home. In 3 132 participants in the Dallas study, researchers determined the risk of stroke, heart attack and death in connection with a clinical systolic blood pressure reading of 130 mm Hg. During the 11-year follow-up, researchers also determined that people at high blood pressure levels measured at home had the same risk of heart disease as people with similar levels as measured by medical staff.
Vongpatanasin added that the results were found in conjunction with the American Heart Association / American College of Cardiology 2017 Blood Pressure Guideline.
“It is important to measure blood pressure at home because clinical readings may not reflect a person’s true blood pressure. Some people have higher readings in the clinic due to the” white fur “phenomenon, while studies have shown that others – especially black – have lower blood pressure measurements in the clinic than at home, “she said.
This study included adults aged 30-65 from two American cities, so the results may not apply to younger or older or adults in different geographic areas, she said.
With the definition of high blood pressure set to 130/80 mm Hg, nearly h alf (46 percent) of American adults have high blood pressure. Researchers have found that at least 30 percent to 45 percent of American high blood pressure monitor monitor their blood pressure at home.
The American Heart Association recommends that consumers follow the correct technique for measuring blood pressure: keep calm and rest for at least 5 minutes before measurements; Avoid caffeine or cigarettes for half an hour before reading. Keep both feet flat on the floor; and avoid talking during the test. At least two readings should be taken one minute apart in the morning before taking medications and in the evening before eating. Preferably, blood pressure readings should be taken for a week beginning a few weeks after a change of treatment regimen and during the week prior to a doctor’s visit.
