High Blood Pressure can Lead to Stroke, Heart Problems & Kidney Disease +
The new study shows public health efforts to improve blood pressure control are working, but “there are still disparities that still affect minorities,” said senior author Dr. Edgar Argulian, of Mt. Sinai St. Luke’s Hospital in New York City.
Treatment of high blood pressure is improving in the United States, but a new study suggests White people are seeing more improvements than Black or Hispanic people.
Blacks and Hispanics were less likely to have their blood pressure under control, compared to Whites, researchers found. Hispanics were also less likely than Whites to be treated for the condition.
“It probably means we need to tweak those efforts,” he said.
The American Heart Association (AHA) recommends keeping systolic blood pressure (the top number of a reading) below 120 millimeters of mercury (mmHg). Diastolic blood pressure (the bottom number) should be below 80 mmHg.
High blood pressure, aka hypertension, can lead to stroke, heart problems, kidney disease and other health issues, according to the AHA.
For the new study, the researchers analyzed data collected from 8,796 US adults with high blood pressure between Y’s 2003 and 2012 as part of the National Health and Nutrition Examination Survey.
Blood pressure treatment and control increased during that time period, the researchers write in Circulation: Cardiovascular Quality and Outcomes.
Treatment rates increased from about 66% in Y’s 2003-2004 to about 77% in Y’s 2010-2012. The proportion of people who got their blood pressure under control increased from 33 to 45% over the same frame.
White people tended to do better on a variety of measures, however.
About 74% of Whites, 71% of Blacks and 61% of Hispanics were being treated for their high blood pressure over the course of the study, the researchers found.
All 3 groups experienced substantial improvement in hypertension control over the course of the study.
But while roughly 43% of Whites had their hypertension under control during the study period, only about 37% of Blacks and about 31% of Hispanics could say the same.
Doctors are treating Blacks nearly as often as Whites for high blood pressure, the researchers note, but Blacks are still less likely to have the condition under control.
Black people are particularly predisposed to high blood pressure and more aggressive forms of the condition.
Unlike Blacks, Hispanics were not treated as aggressively as Whites for high blood pressure. They were also less likely to have their condition under control.
“There is no biological evidence to suggest that Hispanics are more vulnerable to loss of blood pressure control,” lead author Dr. Anna Gu, of St. John’s University in New York said.
For Hispanics, factors like access to health insurance and language barriers may be obstacles to getting appropriate care, Dr. Gu said.
“One of the things we should get out of this study is what a bad job we’re doing controlling blood pressure across the board,” said Dr. Leslie Cho, who directs the Cleveland Clinic’s Women’s Cardiovascular Center in Ohio.
Doctors can be better at providing the best proven treatments for individual patients, said Dr.Cho, who was not involved with the new study.
For example, high blood pressure among Black people responds well to drugs known as calcium channel blockers and diuretics.
People should be encouraged to monitor their blood pressure at home, she added.
Dr. Argulian said treating hypertension is a complex issue that goes beyond merely giving patients pills to take. Blood pressure control needs to take into account many lifestyle factors like weight and diet, but also social factors like insurance access and ability to get and take medications, he said.
