What a local expert says can raise the risk of having a heart attack or stroke.

Milwaukee

New research discussed by Dr. Jeff Ponthoff of UW Health indicates that walking for 15 minutes at a time is more beneficial for reducing heart attack risk than spreading steps over several short periods throughout the day. A study involving about 33,000 participants found that those who took dedicated 15-minute walks had a greater reduction in heart risk compared to those who accumulated steps in brief intervals.

Additionally, a meta-analysis of 180 studies confirms that common viral infections, such as influenza, COVID, shingles, and hepatitis, are associated with an increased risk of heart attack and stroke within 30 days of infection. The report also notes that Canada, with over 5,000 measles cases, is at risk of losing its measles elimination status, a situation mirrored in the United States, partly due to rising anti-vaccination sentiment.

What can raise risk of heart attack, stroke?

And we're following several related health stories for you. And to help us break it all down is Dr. Jeff Ponthoff from UW Health. Great to see you, Dr. Ponthoff. Let's start with this. According to research, extending the length of your daily walks, something a lot of us do, can benefit your heart. Tell us exactly why that might be. Yeah, I think there's been a lot of research recently that says, hey, you don't need to be a gym rat. You don't have to exercise for hours on end every week. But this puts a little bit different spin on it. This looked at about 33,000 individuals who did not 10,000 steps per day, but about five to 8,000 steps per day, and split them up into people who did that kind of just doing their normal tasks, going to the mailbox and back, like less than five minutes, versus folks that actually spent 15 minutes getting those steps in. So going for a walk or something like that. And they found that the reduction in heart risk or heart attacks is much greater in those that did the dedicated 15 minutes of walking rather than those who, you know, walked for two to three minutes, you know, four or five times per day. So I think the take home is, is if you can find the time to go for a walk, you know, do a formal walk, walk for 15 minutes, going to the mailbox and back a couple of times a day, better than nothing, but 15 minutes at a time seems to have more benefit. Yeah, free to do as well, something we can probably all fit into our day somewhere. Let's keep talking heart health. Common viral infections can up your risk of heart attack and stroke. So what is new research revealing when it comes to this? Yeah, so, you know, not so much new research. So there's been a lot of studies that have been published around this association of people who come down with a viral infection and then go on in the next 30 days to have a heart attack. This study actually looked at about 180 studies like that. We call this a meta-analysis and found out that this association is true. So individuals who come down with say influenza, COVID, shingles, some hepatitis viruses, within the next 30 days, they have an increased risk of having a heart attack. Why do we think this happens? When you have these infections, your immune system gets ramped up, it causes inflammation, and that can cause blood clots to form in your blood vessels, which if it goes and plugs your heart up as a heart attack, if it plugs your brain up is a stroke. So this association was kind of known. This study really puts a good summary to it. Very interesting. Okay, let's shift here a little bit and talk about our neighbors to the North. Canada could lose measles elimination status due to a year-long outbreak there. What's going on in Canada? Yeah, so we've talked a lot about measles here in the United States and we're also at risk of losing our measles elimination status, but Canada is also having their own measles outbreak, a little over 5,000 cases up there. Basically to lose your elimination status means that you have a strain of measles that you've been unable to contain for 12 continuous months. It looks like we may lose that elimination status both in Canada and in the United States. Some of it is kind of like the anti-vaccination kind of sentiment that's been present since after the pandemic, but we are seeing a lot of measles cases in North America as well as around the world right now. Yeah, some changes certainly on the horizon, both in Canada and as you mentioned, here we're in the U.S. when it comes to measles. Dr. Ponoff, great to see you. Thanks for your time and your insight this afternoon.
