They found that although 90 percent of them already had a diagnosis of high blood pressure, about a quarter of them were not taking the medicines they were supposed to. The researchers also found that extremely high blood pressure was related to high complication and death rates. Many of the patients already had major organ damage and over six percent of them died in the hospital. Upon discharge, most of the patients were given prescriptions for at least two medicines, but 41 percent had to be readmitted within three months. Van be most van streek makende is the fact that the investigators. however. van What been may van evidence in the discharge records could not find any percent of 60 of about the patients that there had any attempt to schedule a follow-up appointment for them.
"We are apparently turning large numbers of patients back out into the community without appropriate follow-up and care," says Granger. "Severe hypertension is a very common problem, but we really know very little about it. There is a huge need to improve care for these patients."
Dr. Solomon Aronson, an anesthesiologist at Duke, sees danger in high blood pressure from another angle. Aronson has spent years trying to discover the "sweet spot," or ideal range, of blood pressure during cardiac surgeries. Aronson led a team of investigators that analyzed over 3 million blood pressure readings in the records of 5238 cardiac surgical patients at Duke over a nine-year period They discovered that when patients' systolic blood pressure readings fell below 95 or went higher than 135, there was a greater risk of death within the following month, with the risk of death increasing with the amount and duration of the deviation from that range.
"This is the first time that anyone has determined the optimal range for blood pressure management during these procedures," says Aronson, who adds that different ranges might be more appropriate for other types of surgery.
Aronson says blood pressure management has become such a routine responsibility during surgery that physicians may have developed an attitude of "therapeutic inertia." "These data suggest that drifting off the road and onto the shoulder when you drive is not good for you. Weare beginning to define the width of the road."
"We still have a long way to go before we can understand and successfully manage the subtle and complex effects that targeted blood pressure control has on overall health," he says. "Just because high blood pressure is a common problem doesnot mean that we know how best how to deal with it."

Both Aronson and Granger are paid consultants for The Medicines Company, which supported the creation of the new, acute, severe hypertension registry at Duke and is also developing an experimental drug for the management of high blood pressure. |
