Uncontrolled blood pressure is sending more people to the hospital

but women have similar hospital mortality rates

Summary:
The number of people hospitalized for a hypertensive crisis --
when blood pressure increases so much it can cause a heart attack,
stroke or other sudden cardiovascular event -- more than doubled
from 2002 to 2014, according to investigators.



FULL STORY ========================================================================== Thenumber of people hospitalized for a hypertensive crisis -- when blood pressure increases so much it can cause a heart attack, stroke or other
sudden cardiovascular event -- more than doubled from 2002 to 2014,
according to Cedars-Sinai investigators.


==========================================================================
The increase occurred during a period when some studies reported overall progress in blood pressure control and a decline in related cardiovascular events in the U.S. The findings are published in the Journal of the
American Heart Association.

"Although more people have been able to manage their blood pressure over
the last few years, we're not seeing this improvement translate into
fewer hospitalizations for hypertensive crisis," said Joseph E. Ebinger,
MD, a clinical cardiologist and director of clinical analytics at the
Smidt Heart Institute and first author of the study.

Ebinger said there could be various explanations for why a growing number
of people are being hospitalized for dangerously high blood pressure. It
could be that an increasing number may be unable to afford medications to control hypertension or are seeing their blood pressure rise after taking inadequate doses of these drugs. Socioeconomic factors may also make
it difficult for people to avoid a high-salt diet, inactivity, smoking
or other unhealthy behaviors that can contribute to hypertension. These
factors may include limited access to health care, financial insecurity,
or work and family demands.

"We need more research to understand why this is happening and how
clinicians can help patients stay out of the hospital," Ebinger said.

To conduct their study, the investigators analyzed data from the National Inpatient Sample, a publicly available database. The data include a
subset of all hospitalizations across the U.S., providing a picture of nationwide trends.

They found that annual hospitalizations for hypertensive crises more than doubled over a 13-year period. Hospitalizations related to hypertensive
crises represented 0.17% of all admissions for men in 2002 but 0.39%
in 2014.

Hospitalizations related to hypertensive crisis represented 0.16% of
all admissions for women in 2002 but 0.34% in 2014.

The investigators estimated that from 2002 to 2014, there were 918,392 hospitalizations and 4,377 in-hospital deaths related to hypertensive
crisis across the U.S.

The risk of dying from a hypertensive crisis, however, did decrease
slightly overall during the studied time period. Women died at the same
rate as men, even though they had fewer health issues than men who also
were hospitalized for a hypertensive crisis.

"These findings raise the question: Are there sex-specific biologic
mechanisms that place women at greater risk for dying during a
hypertensive crisis?" said Susan Cheng, MD, MPH, director of the Institute
for Research on Healthy Aging in the Department of Cardiology at the Smidt Heart Institute and senior author of the study. "By understanding these processes, we could prevent more deaths among women," added Dr. Cheng,
who is also the Erika J. Glazer Chair in Women's Cardiovascular Health
and Population Science and professor of cardiology.
