How low should you go?
Cardiovascular risk continues to reduce as systolic blood pressure decreases right down to levels as low as 90 mm Hg, according to a new study.
Researchers analyzed data from a cohort of 1,457 participants (mean age, 58 years) who did not have any traditional cardiovascular risk factors and had a systolic blood pressure level between 90 and 129 mm Hg at baseline. Results showed that, during a mean follow-up of 14.5 years, there was an increase in traditional cardiovascular risk factors, coronary artery calcium, and incident cardiovascular events with increasing systolic blood pressure levels.
“We modeled systolic blood pressure on a continuous scale and saw the risk increasing in a linear fashion as blood pressure increased and this occurred right down to 90 mm Hg. We didn’t see any nadir or J-point where there may be an increased risk at lower pressures,” said lead author Seamus Whelton, MD, assistant professor of medicine at the division of cardiology at Johns Hopkins Medicine, Baltimore.
“From an individual level we can now say that in healthy individuals, a systolic pressure in the 90s is not too low. It is a positive thing. And it is recommended to try and keep systolic pressure at these levels if possible by maintaining a healthy lifestyle,” Dr. Whelton said in an interview. Read more.
Asthma tops spending on avoidable pediatric inpatient stays
Asthma costs nearly equaled potentially avoidable hospital bills for diabetes, gastroenteritis, and UTIs combined in a study of in-patient stays among children aged 3 months to 17 years.
Indeed, hospital charges for the treatment of children with asthma made up nearly half of all potentially avoidable pediatric inpatient costs in 2017, according to the Agency for Healthcare Research and Quality.
The cost of potentially avoidable visits for asthma that year was $278 million, versus $284 million combined for the other three conditions, Kimberly W. McDermott, PhD, and H. Joanna Jiang, PhD, reported in an AHRQ statistical brief.
The state inpatient databases of the AHRQ’s Healthcare Cost and Utilization Project included 1.4 million inpatient stays among children aged 3 months to 17 years in 2017, of which 8% (108,300) were deemed potentially preventable.
Rates of potentially avoidable stays for asthma (159 per 100,000 population), gastroenteritis (90 per 100,000), and UTIs (41 per 100,000) were highest for children aged 0-4 years and generally decreased with age, but diabetes stays increased with age, rising from 12 per 100,000 in children aged 5-9 years to 38 per 100,000 for those 15-17 years old, the researchers said.

Adding monoclonal antibodies to Botox for migraine prevention
Adjunctive preventive therapy with a calcitonin gene–related peptide monoclonal antibody (CGRP-mAb) medication is safe and effective in patients with chronic migraine who have only achieved a partial response to onabotulinumtoxinA (Botox) treatment.
Investigators found the CGRP-mAbs significantly reduced the number of headache days and pain severity with adverse event rates similar to those reported in previous trials of these medications.
Although Botox is associated with significant clinical improvement in chronic migraine, it often fails to adequately control headache frequency and additional medications are needed. Three CGRP-mAbs have recently been approved for migraine prevention, with results from clinical trials demonstrating they are effective for both chronic and episodic migraine. Patients treated with Botox had been excluded from these earlier trials, however. Read more.
