MONDAY, October 1, 2018 (HealthDay News) – If your weight, blood pressure, cholesterol, or blood sugar fluctuates, you're at a higher risk of heart attack, stroke, and premature death than people with the readings are more constant. New research suggests.
According to the study, for nearly six years of follow-up, men and women whose readings had changed the most were 127% more likely to die, 43% more likely to have a heart attack, and 41% more likely to die. likely to have a stroke, compared with those whose readings have remained stable.
"The variability of metabolic parameters may play a role in predicting mortality and cardiovascular outcomes," said Dr. Seung-Hwan Lee, lead author of the study, professor of endocrinology at the Faculty of Medicine at the University of Michigan. Catholic University of Korea in Seoul.
Since the study examined data from the past, it can only show a link between the variability of these readings and the risk. He can not prove that variability is the cause of the increased risk of heart attack, stroke or death, the study authors warned.
The researchers also did not examine the reasons why metabolic readings could fluctuate with time.
However, treatment strategies aimed at reducing fluctuations in these parameters should be an objective of prevention of health problems, Lee said.
These strategies may include maintaining blood pressure, cholesterol, and blood glucose levels within normal limits – neither too high nor too low – and maintaining a normal weight – neither too fat nor too thin.
Dr. Gregg Fonarow, professor of cardiology at the University of California at Los Angeles, found these results interesting.
"This opens a new path for taking into account the variation of risk factors over time in estimating the risk of cardiovascular disease," he said. "Better identification of people at high and low risk could translate into better use of prevention strategies and therapies."
But further studies are needed to determine whether treatment strategies that specifically reduce the fluctuations of these parameters will reduce the risk of cardiovascular events and improve health, Fonarow said.
For the study, Lee and his colleagues used Korea's national health insurance system to collect data on more than 6.7 million people who had no heart attack, diabetes, high blood pressure, or high cholesterol level.
