Hypertensive individuals warned against lying flat on their back, says study



Recent findings presented at the Hypertension Scientific Sessions 2023 of the American Heart Association indicate that individuals who experience high blood pressure while lying flat on their backs face an increased likelihood of heart attack, stroke, heart failure, or early death.

According to a study led by Duc M. Giao from Harvard Medical School, assessing blood pressure while in a supine position (lying on one's back) may fail to identify the risk of cardiovascular disease. The research team examined health data from 11,369 participants in the Atherosclerosis Risk in Communities (ARIC) study.

The study revealed that 16 percent of participants without high blood pressure while seated had elevated blood pressure while lying supine, whereas 74 percent of those with high blood pressure while seated also exhibited high blood pressure in the supine position.

These findings emphasize the significance of considering both body position and blood pressure when evaluating the risk of cardiovascular disease. Individuals who had high blood pressure in both seated and supine positions were found to have a 1.6 times higher risk of developing coronary heart disease, a 1.83 times higher risk of heart failure, a 1.86 times higher risk of stroke, a 1.43 times higher risk of premature death overall, and a 2.18 times higher risk of dying from coronary heart disease.

The elevated risks observed in both groups were not influenced by differences in the use of blood pressure medication.
