Study ties blood pressure, cholesterol fluctuations to heart attack risk
New research suggests that fluctuations in blood pressure, cholesterol, and blood sugar levels in healthy people is tied to an increased risk of heart attack or stroke. Researchers looked at data from nearly 7 million people in Korea with no history of heart attack, diabetes, high blood pressure, or high cholesterol. People with the most variability in their measurements from one doctor’s visit to the next were 43 and 41 percent more likely to have a heart attack or stroke, respectively, than people with stable measurements, the study’s authors report. The big caveat: The study doesn’t show cause and effect.
