BLOOD PRESSURE CHANGES
ANCHOR LEAD: BLOOD PRESSURE VARIES WITH THE SEASON, ELIZABETH TRACEY REPORTS
Keeping blood pressure under control is known to help reduce heart disease risk, but now a new study reveals that blood pressure varies with the season and may therefore spike out of a desirable range without anyone knowing. That’s according to a study described at the recent American Heart Association meeting. Rick Lange, a cardiologist at Johns Hopkins, explains.
LANGE: This was a study conducted in over 400,000 patients, and they followed their blood pressure throughout the year, in fact over five years, and what they determined is that a significant number of people who have a well controlled blood pressure in the summer don’t have a well controlled blood pressure in the winter, and that is, it goes up. And in about fifty to sixty percent of individuals, their blood pressure goes up in the winter compared to the summer. :27
Lange recommends that everyone monitor their own blood pressure at home, at various times of the day as well as seasonally, so medications can be adjusted accordingly. I’m Elizabeth Tracey reporting.
