Hypertension: high diastolic pressure is also a sign of cardiovascular risk



Two blood pressure, systolic (high) and diastolic (low) readings independently predict the risk of heart attack or stroke in a large study coordinated by Kaiser Permanente, which encompassed more than 36 million blood pressure readings by more than 1 million people during ambulatory visits between 2007 and 2016.

study. published in the New England Journal of Medicine & # 39;. goes against decades of research Previous studies have shown that high systolic blood pressure, which measures the strength with which the heart pump blood into the artery, more determinant as a risk factor than diastolic pressure, indicating pressure on the artery when the heart lies between heartbeat,

Both affect

But it is true that after adjusting the data for possible confusing factors,Researchers have concluded that although systolic pressure has a greater impact, both clearly affect the risk of heart or stroke.regardless of the definition used for high, even high blood pressure at the lower threshold of 130/80 mm Hg.

"Controversy over whether systolic blood pressure, diastolic blood pressure, or both contribute to cardiovascular risk, lasts for a long time." This analysis uses a large amount of longitudinal data. convincingly shows that both are important, and shows that in people who are generally healthy, lower blood pressure is better, "concludes Deepak L. Bhatt, Chief Research Officer, Chief Executive of Emergency Cardiovascular Services at Brigham and Women's Hospital and Professor of Medicine at Harvard Medical School.
