Should clinic BP be routinely measured lying down?
new preliminary research suggests.
An analysis of data from a long-running Atherosclerosis Risk in Communities (ARIC) study of more than 11,000 adults showed that those who had hypertension while supine were at elevated risk for cardiovascular disease (CVD) independently of their having hypertension while seated.
“If blood pressure is only measured while people are seated upright, cardiovascular disease risk may be missed if not measured also while they are lying supine on their backs,” lead investigator Duc M. Giao, a researcher and a fourth-year medical student at Harvard Medical School, Boston, said in a news release.
Mr. Giao presented the findings at the Hypertension Scientific Sessions.
Take seated and supine BP in clinic?
Hypertension while asleep is strongly associated with CVD and death, but whether hypertension detected in clinic while the patient is lying flat is a risk factor for CVD independently of the patient’s BP while seated remains unclear.
To investigate, Mr. Giao and colleagues reviewed health data for 11,369 adults (mean age, 54 years; 56% women; 25% Black persons) from the longitudinal ARIC study. None had a history of coronary heart disease (CHD), heart failure (HF), or stroke at baseline.
As part of the study, data on supine and seated BP were obtained during the enrollment period at ARIC visit 1, which took place between 1987 and 1989. Both seated and supine hypertension were defined as systolic BP ≥ 130 mm Hg or diastolic BP ≥ 80 mm Hg.
The data revealed that 16% of those without seated hypertension had supine hypertension, while 74% of those with seated hypertension had supine hypertension.
Despite adjusting for seated hypertension, during a median follow-up of 25-28 years, supine hypertension was associated with an increased risk for incident CHD (adjusted hazard ratio, 1.60; 95% confidence interval, 1.45-1.76), HF (aHR, 1.83; 95% CI, 1.68-2.01), stroke (aHR, 1.86; 95% CI, 1.63-2.13), fatal CHD (aHR, 2.18; 95% CI, 1.84-2.59), and all-cause mortality (aHR, 1.43; 95% CI, 1.35-1.52).
The results did not differ by antihypertensive medication use (P > .05).
For patients who had hypertension while supine but not while seated, elevations in risk were similar to those of peers who had hypertension while both seated and supine.
“Our findings suggest people with known risk factors for heart disease and stroke may benefit from having their blood pressure checked while lying flat on their backs,” Mr. Giao said in the conference news release.
“Efforts to manage blood pressure during daily life may help lower blood pressure while sleeping. Future research should compare supine blood pressure measurements in the clinic with overnight measurements,” Mr. Giao added.
Busy clinical practice
In a comment, Wanpen Vongpatanasin, MD, clinical chair for the conference, sponsored by the American Heart Association, said, “This finding highlights the importance of sustained control of BP in all body positions.”
She noted that many population-based studies have shown that nighttime BP independently predicts CV outcomes. “It’s unclear whether the timing of BP measurement (night vs. day) or the position (as most people sleep in supine position at night) explains this phenomenon.”
The study by Mr. Giao and colleagues suggests that “supine BP may be one explanation, as it has as much impact on long-term CV outcome as seated BP,” said Dr. Vongpatanasin, professor of internal medicine and director of the hypertension section, cardiology division, UT Southwestern Medical Center in Dallas.
However, “in busy clinical practice, it is impossible to do both seated and supine, as well as standing BP,” said Dr. Vongpatanasin.
“Additional studies are needed to determine what is considered to be the cutoff for normal supine BP and how to incorporate it in management of hypertension,” she added.
The study had no commercial funding. Mr. Giao and Dr. Vongpatanasin have disclosed no relevant financial relationships.

‘New dawn’ for aldosterone as drug target in hypertension?
Once-daily treatment with the selective aldosterone synthase inhibitor lorundrostat (Mineralys Therapeutics) safely and significantly reduced blood pressure in adults with uncontrolled hypertension in a phase 2, randomized, controlled trial.
Eight weeks after adding lorundrostat (50 mg or 100 mg once daily) or placebo to background therapy, the medication lowered seated automated office systolic BP significantly more than placebo (−9.6 mm Hg with 50 mg; −7.8 mm Hg with 100 mg), with the greatest effects seen in adults with obesity.
“We need new drugs for treatment-resistant hypertension,” study investigator Steven Nissen, MD, chief academic officer at the Heart Vascular & Thoracic Institute at the Cleveland Clinic, said in an interview. Lorundrostat represents a “new class” of antihypertensive that “looks to be safe and we’re seeing very large reductions in blood pressure.”
Results of the Target-HTN trial were published online in JAMA to coincide with presentation at the Hypertension Scientific Sessions, sponsored by the American Heart Association.
Aldosterone’s contribution ‘vastly underappreciated’
Excess aldosterone production contributes to uncontrolled BP in patients with obesity and other associated diseases, such as obstructive sleep apnea and metabolic syndrome.
“Aldosterone’s contribution to uncontrolled hypertension is vastly underappreciated,” first author and study presenter Luke Laffin, MD, also with the Cleveland Clinic, said in an interview.
Aldosterone synthase inhibitors are a novel class of BP-lowering medications that decrease aldosterone production. Lorundrostat is one of two such agents in advanced clinical development. The other is baxdrostat (CinCor Pharma/AstraZeneca).
The Target-HTN randomized, placebo-controlled, dose-ranging trial enrolled 200 adults (mean age, 66 years; 60% women) with uncontrolled hypertension while taking two or more antihypertensive medications; 42% of participants were taking three or more antihypertensive medications, 48% were obese and 40% had diabetes.
The study population was divided into two cohorts: an initial cohort of 163 adults with suppressed plasma renin activity at baseline (PRA ≤ 1.0 ng/mL per hour) and elevated plasma aldosterone (≥ 1.0 ng/dL) and a second cohort of 37 adults with PRA greater than 1.0 ng/mL per hour.
Participants were randomly assigned to placebo or one of five doses of lorundrostat in the initial cohort (12.5 mg, 50 mg, or 100 mg once daily or 12.5 mg or 25 mg twice daily).
In the second cohort, participants were randomly assigned (1:6) to placebo or lorundrostat 100 mg once daily. The primary endpoint was change in automated office systolic BP from baseline to week 8.
Among participants with suppressed PRA, following 8 weeks of treatment, changes in office systolic BP of −14.1, −13.2, and −6.9 mm Hg were observed with 100 mg, 50 mg, and 12.5 mg once-daily lorundrostat, respectively, compared with a change of −4.1 mm Hg with placebo.
Reductions in systolic BP in individuals receiving twice-daily doses of 25 mg and 12.5 mg of lorundrostat were −10.1 and −13.8 mm Hg, respectively.
Among participants without suppressed PRA, lorundrostat 100 mg once daily decreased systolic BP by 11.4 mm Hg, similar to BP reduction in those with suppressed PRA receiving the same dose.
A prespecified subgroup analysis showed that participants with obesity demonstrated greater BP lowering in response to lorundrostat.
No instances of cortisol insufficiency occurred. Six participants had increases in serum potassium above 6.0 mEq/L (6.0 mmol/L) that corrected with dose reduction or drug discontinuation.
The increase in serum potassium is “expected and manageable,” Dr. Laffin said in an interview. “Anytime you disrupt aldosterone production, you’re going to have to have an increase in serum potassium, but it’s very manageable and not something that is worrisome.”
A phase 2 trial in 300 adults with uncontrolled hypertension is currently underway. The trial will evaluate the BP-lowering effects of lorundrostat, administered on a background of a standardized antihypertensive medication regimen. A larger phase 3 study will start before the end of the year.
‘New dawn’ for therapies targeting aldosterone
The author of an editorial in JAMA noted that more 70 years after the first isolation of aldosterone, then called electrocortin, “there is a new dawn for therapies targeting aldosterone.”
“There is now real potential to provide better-targeted treatment for patients in whom aldosterone excess is known to contribute to their clinical condition and influence their clinical outcome, notably those with difficult-to-control hypertension, obesity, heart failure, chronic kidney disease, and the many with yet-to-be-diagnosed primary aldosteronism,” said Bryan Williams, MD, University College London.
The trial was funded by Mineralys Therapeutics, which is developing lorundrostat. Dr. Laffin reported that the Cleveland Clinic, his employer, was a study site for the Target-HTN trial and that C5Research, the academic research organization of the Cleveland Clinic, receives payment for services related to other Mineralys clinical trials. Dr. Laffin also reported receipt of personal fees from Medtronic, Lilly, and Crispr Therapeutics, grants from AstraZeneca, and stock options for LucidAct Health and Gordy Health. Dr. Nissen reported receipt of grants from Mineralys during the conduct of the study and grants from AbbVie, AstraZeneca, Amgen, Bristol-Myers Squibb, Lilly, Esperion Therapeutics, Medtronic, grants from MyoKardia, New Amsterdam Pharmaceuticals, Novartis, and Silence Therapeutics. Dr. Williams reported being the unremunerated chair of the steering committee designing a phase 3 trial of the aldosterone synthase inhibitor baxdrostat for AstraZeneca.
