Research highlights:
- An analysis of data from a longitudinal study of more than 11,000 adults from four diverse communities in the United States found that people with high blood pressure were more likely to suffer from high blood pressure while sitting upright and while sleeping on their backs. found that adults with high blood pressure were at increased risk of high blood pressure. Upright and supine positions reduce heart disease, stroke, heart failure, or early death compared to adults without high blood pressure.
- Adults who have high blood pressure when lying on their backs but not when sitting upright are as likely to have heart attacks, strokes, and heart failure as adults who have high blood pressure in both supine and upright positions. , or increased risk of premature death.
- The increased risk of heart disease, stroke, heart failure, or early death did not differ by the type of blood pressure medication used among participants.

BOSTON, September 7, 2023 — People with high blood pressure are at increased risk of heart attack, stroke, heart failure, or premature death when sleeping on their backs, according to a new study to be presented at the American Heart Association’s Hypertension Science Conference. I understand. Session 2023 will be held in Boston from September 7th to 10th, 2023. This conference is a premier scientific exchange focused on recent advances in basic and clinical research on the relationship between hypertension and heart disease, kidney disease, stroke, obesity, and genetics.
The autonomic nervous system regulates blood pressure at various locations in the body. But when you’re sitting or standing upright, gravity can cause blood to pool, and your body can’t regulate blood pressure properly when you’re lying down, sitting, or standing. The authors point out that there is.
“If blood pressure is only measured when people are sitting upright, and not when they are lying on their backs, cardiovascular disease risk may be missed,” said the lead author of the study. said author and researcher Duc M. Giao, a fourth MD.thM.D. student at Harvard Medical School in Boston.
To examine body position, blood pressure, and heart health risks, researchers looked at health data for 11,369 adults from the Atherosclerosis Risk in Communities (ARIC) Longitudinal Study. Data on supine and sitting blood pressure were collected during his ARIC Visit 1, an enrollment period that took place between 1987 and 1989. Participants had their blood pressure measured in a slightly reclined position at the clinic. The average age of participants at that time was 54 years. 56% of the group identified as women. And 25% of participants identified themselves as black. Participants in this analysis were followed for an average of 25 to 28 years through their fifth ARIC visit, which includes health data collected from her 2011 to her 2013.
The researchers’ findings included:
- Among participants who did not have high blood pressure while sitting (defined in this study as having upper and lower blood pressure readings of 130/80 mm Hg or higher), 16% of participants did not have high blood pressure while sitting (defined in this study as having upper and lower blood pressure readings of 130/80 mm Hg or higher). I had high blood pressure. ), compared with 74% of those with sitting hypertension and some with supine hypertension.
- Compared with participants who did not exhibit hypertension while sitting and supine, participants who exhibited hypertension while sitting and supine had a 1.6 times higher risk of developing coronary heart disease. 1.83 times higher risk of developing heart failure. 1.86 times higher risk of stroke. Her overall risk of early death is 1.43 times higher.2.18 times more likely to die from coronary heart disease
- Participants with high blood pressure while supine but not hypertensive while sitting had an increased risk, as did participants with high blood pressure in both sitting and supine positions.
- Differences in blood pressure medication use did not influence these increased risks in either group.
“Our findings suggest that people with known risk factors for heart disease or stroke may benefit from measuring their blood pressure while lying on their back,” Zhao said. he said.
“Efforts to manage blood pressure in daily life may help lower blood pressure during sleep. Future studies should compare supine blood pressure measurements in the clinic with nighttime blood pressure measurements.” there is.”
The study had the limitation of focusing on adults who were middle-aged at the time of enrollment, and the results may not be as generalizable to older adults, Zhao said.

background:
- The Atherosclerosis Risk in Communities (ARIC) study enrolled 15,792 U.S. adults from 1987 to 1989 to investigate the causes of atherosclerosis (plaque or fat buildup within the arteries). This is an ongoing community-based cohort. Participants in the ARIC study were 45 to 65 years old at study entry and were from rural (Forsyth County, North Carolina, and Washington County, Maryland) and urban (Minneapolis and Jackson, Mississippi) areas of the United States. Research and data from ARIC clinical visits, including hospital record excerpts, electrocardiogram tracking, physician and coroner questionnaires, and death certificate data, are used to diagnose atherosclerosis, heart disease, kidney disease, diabetes, stroke, and stroke. This led to findings and guidelines regarding. Decline in cognitive function.
- The 2017 ACC/AHA Guidelines for the Prevention, Detection, Evaluation, and Control of Hypertension in Adults classifies hypertension as having upper and lower limits of 130/80 mm Hg or higher, which is the standard used in this guideline. This is the definition of high blood pressure. study.
