Blood pressure is healthier when it's low rather than high, right? Well, a new study in JAMA, the Journal of the American Medical Association, shows there is one exception, when doctors want to see high blood pressure.
Researchers at Northwestern University School of Medicine found that if a patient with heart failure has high blood pressure while being admitted into the hospital he or she has less risk of dying, compared to the heart patient who is admitted with low blood pressure.
"During stress, or at the time of admission, it appears that when you have high blood pressure for a limited amount of time, let's say hours, that may indicate that your heart is stronger. So it's not that the blood, that the high blood pressure is good, but it's a measure of the strength of the heart," said Dr. Mihai Gheorghiade, of Northwestern University School of Medicine.
The Northwestern study followed nearly 50,000 in this country who were hospitalized with heart failure.
