Latest / Pediatrics Now: Cases Updates and Discussions for the Busy Pediatric Practitioner / Energy Drinks Can Damage a Healthy Heart; Plus When Anxiety Symptoms Are Really Cardiac
Transcript
- 0:00Part is that there's a local high school that has a vending machine for the
- 0:06high school students to purchase these in school, on campus. What?
- 0:11And a lot of the high schools have coffee bars now. Anyway. I know. I know.
- 0:16I'm Holly Wehment, and this is Pediatrics Now, brought to you by UT Health's
- 0:22Department of Pediatrics.
- 0:24A recent case involving the death of a teenage cheerleader has raised new questions
- 0:28about energy drinks and cardiovascular health in young people.
- 0:32Although a direct link has not been established, it's an opportunity to review
- 0:37what we know and what we don't know about these increasingly popular beverages.
- 0:42And we know pediatricians are being asked about this.
- 0:46I'm thrilled today because Dr. Elaine Maldonado is joining me here in our podcast
- 0:51studio, and she has been a pediatric cardiologist since 2005 on faculty.
- 0:58Dr. Maldonado, thank you so much for being here today in the podcast studio.
- 1:02Thanks, Holly. It's good to see you. My son was saying to me,
- 1:06Mom, most of my friends, what is the most common is to drink energy drinks.
- 1:12He's 18 years old, and it's uncommon if one of his friends doesn't ever drink
- 1:18the energy drinks. I just, I couldn't believe that. It's, I mean,
- 1:22it sounds like they're wildly popular.
- 1:24Yeah, I think that's true, Holly. My experience has been, you know,
- 1:29parents bringing their children into the clinic and having concerns about energy
- 1:34drinks, caffeine intake, all of the above.
- 1:38And it's a very common thing nowadays for kids.
- 1:41And a lot of the energy drinks, they come in these cans. It's a slender can,
- 1:46and it's kind of the in thing to drink them, but it can have so much caffeine in just one can.
- 1:52That's true. Yeah. And I think recently, one of the concerns that folks have
- 1:56had is marketing and how the energy drinks are marketed towards kids.
- 2:02You know, the cans have all this colorful marketing on them and.
- 2:08It's been a concern. Do you have any advice when parents are asking pediatricians
- 2:12about the cheerleader who passed away and they're asking about that case?
- 2:19What do you say? Yeah, it's such a sad situation when you think about that young
- 2:24lady. So tragic. So tragic.
- 2:26We obviously don't know exactly what led to her death.
- 2:31But when parents come in with specific questions about energy drinks,
- 2:35I think the easy answer is to let parents know that there really is no benefit
- 2:40for children to drink those energy drinks.
- 2:43There is no nutritional benefit.
- 2:45And caffeine intake for kids, if you look at our American Academy of Pediatrics
- 2:50website and recommendations on caffeine intake, especially for younger children,
- 2:55there really is no nutritional benefit for them.
- 2:58And it can potentially have an impact on their growth and their development
- 3:01because they're still growing so much. Their brains are changing.
- 3:05So the easy answer is they just shouldn't have it.
- 3:09And I think that could be something that could really resonate with kids.
- 3:13This could affect your growth.
- 3:15Yes, and your brain development, your performance.
- 3:19A lot of the kids that I know drink caffeine just on a daily basis just to function,
- 3:26just to get through the day, get through school. And unfortunately,
- 3:29most of us as adults drink caffeine on a regular basis, too.
- 3:32Yes, they're seeing us do that.
- 3:34Right. So that makes it hard. It does. And most of these energy drinks in particular,
- 3:40it's okay for kids to purchase them. It's legal.
- 3:44Do you think that it should be illegal? Personally, I think it probably should
- 3:50be. I don't think kids have any reason to be drinking energy drinks or that much caffeine.
- 3:56A lot of those cans or bottles can have over 200 milligrams of caffeine each
- 4:01or per serving. And some of the cans are two to three servings per can.
- 4:05So the amount of caffeine in those is pretty significant at times.
- 4:09It depends on the brand and, you know, how big the can is.
- 4:13And there's a high school here in town that has it in their vending machines.
- 4:18A lot of people may not realize the dangers, right? Right. There are some high
- 4:22schools that have those in vending machines here in San Antonio.
- 4:26It has become more and more popular across the country for high schools to have
- 4:31coffee bars for kids available to them.
- 4:35The whole time they're at school, they can just go and get free coffee.
- 4:39Yes, and then at the fundraiser for my daughter's school, they had a coffee
- 4:43bar was part of the main fundraiser throughout the day at school.
- 4:46I was so surprised. Yeah.
- 4:50So we're seeing more children and teens consuming these energy drinks.
- 4:54What happens physiologically when a child consumes a high amount of caffeine
- 4:58or stimulant-containing beverages?
- 5:01Yeah, that's a great question. You know, a lot of times when patients come into
- 5:04my clinic, the complaints are things like palpitations or feeling an irregular
- 5:09heartbeat or a fast heartbeat.
- 5:12Other times they come in with concerns about chest pain. So there are many cardiac
- 5:16symptoms like those that I just mentioned that caffeine can cause or exacerbate.
- 5:21And so when they come in with those symptoms, that's one of the first things
- 5:25we talk about is, you know, I phrase it as, are you a big caffeine drinker?
- 5:30Do you enjoy Starbucks? Do you like your Cokes? And all of those questions,
- 5:35when we talk to kids about that, I try to correlate their caffeine intake as
- 5:40a potential cause for the symptoms that they're coming in with.
- 5:44Because it's so common, so that's kind of what you're, you know,
- 5:47this could be causing it.
- 5:49Is it difficult with adolescents because they may not necessarily be telling
- 5:54you, or with patients in general, you don't know if they're telling you exactly
- 5:58what they're drinking, what the intake is, how much it is. Their parents right there, they may.
- 6:03That's right. That's right. Yeah. And especially with older teenagers,
- 6:07you know, you want to give them some degree of autonomy.
- 6:10They're growing up. They're going to be young adults soon.
- 6:13But I try to stress to them how that can affect them.
- 6:17And maybe they could feel better if they at least cut back on their intake.
- 6:22Because even if they're sleeping, the sleep might not be as deep of a sleep,
- 6:27if you have caffeine in your system.
- 6:28Yeah, potentially. And depends on what time you're drinking caffeine.
- 6:31I remember one particular patient who was telling me she was having coffee late
- 6:37into the night to study and then was wondering why she couldn't go to sleep.
- 6:41Right. And you're like, well, this is why. That's right.
- 6:45Can energy drinks affect heart rhythm, blood pressure, or the cardiovascular
- 6:49system in otherwise healthy children?
- 6:51So we know the answer is yes. Absolutely.
- 6:53Yeah, because of the caffeine and the caffeine content.
- 6:58Are there certain children who may be at greater risk, such as those with an
- 7:03undiagnosed heart condition?
- 7:05Yes. You know, if you have an undiagnosed congenital heart disease that can
- 7:09potentially impact your cardiac output, which would affect your blood pressure, absolutely.
- 7:15If you have an excessive amount of caffeine in your system and it affects your
- 7:19heart rate, it could definitely affect your cardiac output and your ability,
- 7:24to have enough cardiac output for your body to function.
- 7:28When you hear about that tragic case, like the Texas teen, what is the most
- 7:33important message for physicians regarding association versus causation?
- 7:40When patients come into our clinics, we obviously need to make sure that there
- 7:43isn't an underlying cardiac etiology as the primary reason for them to be having their symptoms.
- 7:49But part of our job is to include a very detailed history and to educate patients.
- 7:56You know, just because you have a normal heart and it's functioning normally
- 8:00and you're doing well, that doesn't mean that,
- 8:04if you intake a certain amount of caffeine or lots of energy drinks or do things
- 8:09that maybe you shouldn't be doing, that it won't affect your heart and how it
- 8:12functions in the future.
- 8:14And so it's important for them to understand that. Mm-hmm.
- 8:19So it could be dangerous for anyone. For anyone. For anyone. Yeah.
- 8:24And it's also tough, too, because especially teenagers, if they're not supposed
- 8:30to be doing something then and the parent is telling them not to do it,
- 8:34then they might want to do it more.
- 8:37But maybe they'll listen to the pediatrician. I feel like my kids listen to
- 8:39their pediatrician. They'll follow what their pediatrician says to do.
- 8:43And I had been saying it for weeks.
- 8:47That's interesting you mentioned that because that's a very common occurrence, I think, in my clinic.
- 8:51You know, we'll go through the entire process of, you know, a history and a
- 8:54physical and all the diagnostic testing. And then we come to the end where we're counseling.
- 8:59And parents will often say, you know, it's interesting because everything you
- 9:03just told them, I have been telling them for months, sometimes even years.
- 9:08And it does, sometimes it just hits different when it's coming from someone
- 9:12who's not your mom or your dad, especially for teenagers.
- 9:16That's not true for all teenagers, but yes, that's a very common thing that parents tell me.
- 9:21And pediatricians have the power.
- 9:24It's amazing the difference that you all are making in kids' lives and our listeners.
- 9:30So can you tell me again, what does the American Academy of Pediatrics recommend
- 9:34regarding energy drink consumption in children and adolescents? Bottom line.
- 9:39Specifically related to caffeine, which we know is part of energy drinks.
- 9:44The American Academy of Pediatrics statement tells parents, families,
- 9:49patients, there's really no role for a caffeine intake in children.
- 9:54It just, there's no benefit, and they recommend that kids just don't intake caffeine.
- 9:59You're the mom of two adult sons. What would you say to your sons about this, or what do you say?
- 10:07Energy drinks just really are something you shouldn't have.
- 10:11I am fortunate that my adult children just don't really enjoy drinking coffee.
- 10:16They've never had energy drinks that I know of.
- 10:21But they are not coffee drinkers. I myself do drink coffee about a cup a day.
- 10:26But yeah, my stance is there's no need to have energy drinks.
- 10:31What about for our pediatrician listeners who work long hours,
- 10:34any guidance there for the pediatrician? I love coffee, too,
- 10:37but what guidance can you give us?
- 10:41I mean, as adults, obviously, we have to be smart. We have to keep our heart
- 10:45health in mind, probably more so than younger kids.
- 10:48I think some caffeine intake is okay. We just have to be mindful about the amounts.
- 10:53How many milligrams is okay?
- 10:55You know, in general, for a normal, healthy adult, under 400 milligrams a day is what's recommended.
- 11:03I think probably people should stick to well below that amount, if possible.
- 11:07I noticed an energy drink can a few weeks ago. It was in our recycle bin.
- 11:12So I'm assuming it was my 18-year-old son who drank it. And he didn't mention it.
- 11:16I had no idea. I didn't see it before then. And it was just,
- 11:20you know, and I brought it up and he said that it was before a test or something.
- 11:25And I remember him asking me if I, before the SAT, if I drink a Red Bull,
- 11:30will it help my performance? And I said, no, I don't see how it would.
- 11:35But do you have any advice there?
- 11:38Yeah, it's so hard because it has become so commonplace. But,
- 11:42you know, there are alternatives that are probably a little bit healthier and
- 11:45have much less caffeine.
- 11:47Things like green tea, where there probably are some health benefits to the
- 11:52tea, maybe not the caffeine.
- 11:54There are choices that they can make. It is tough. You know,
- 11:57there are so many other factors that affect kids' cardiac symptoms.
- 12:01You know, and nowadays kids are under so much stress.
- 12:05Right. It's tough, but sticking to habits, having a routine,
- 12:09getting a good amount of sleep, drinking plenty of water, all of it sounds like
- 12:13common sense stuff, but it helps kids to do better in school and to just feel better.
- 12:20Elaine, many energy drinks, as you know, contain not only caffeine,
- 12:24but other ingredients like taurine and alcohol.
- 12:29Garana? Am I saying that right? I don't know. Anyway, do these combinations
- 12:34raise additional concerns?
- 12:36So there's these ingredients we can't even pronounce that are in there.
- 12:40And who knows how much caffeine, but it's more caffeine than even is in coffee.
- 12:45Yeah, and that's a good point that you bring up, Polly, because depending on
- 12:48the energy drink and how it's being marketed, that will determine if there's
- 12:53any oversight from the FDA or from another agency or any oversight at all into the ingredients.
- 13:00And so that does complicate things when it comes to energy drinks because you
- 13:04sometimes just don't know what's in there and how much.
- 13:08And I guess some of them, I don't know if all of them would have in tiny writing,
- 13:12should not be consumed by someone under 18. Exactly. Yeah.
- 13:17Actually, most of the ones that I've seen, and in particular the ones that I
- 13:21know are being sold in some of the high schools here in town,
- 13:24It says that on the can, not intended for kids under 18 years of age. Wow.
- 13:29And it's in the vending machine. Correct.
- 13:32What are the key take-home points every pediatrician should communicate to families?
- 13:38You know, I think the common sense points that we talked about,
- 13:40you know, try to help your children to have a routine.
- 13:44It's tougher as they get older, but it is important for them to try to go to
- 13:49bed at the same time and wake up at the same time.
- 13:52You know, get a set amount of sleep every night.
- 13:55Try to have regular meals. Drink water regularly. Exercise on a daily basis if you can.
- 14:02All of those things are important to keep kids engaged and help with their school performance.
- 14:08And all of those things actually help them as opposed to energy drinks and caffeine,
- 14:13which really have no benefit to them.
- 14:16And it's not going to make them do better on the test. No. No,
- 14:19unfortunately. Okay, I was right.
- 14:22So also I've noticed adolescents, if you're not in a sport, you might be going
- 14:26throughout the whole day without any exercise because a lot of schools don't have P.E.
- 14:32For adolescents or maybe they'll have it half the year. But by a certain age,
- 14:37you're just going from sitting to sitting to sitting.
- 14:41That's right. Yeah. And that's another thing that we talk to families about,
- 14:44you know, having a scheduled time where even as a family, you guys do some sort
- 14:49of physical activity together.
- 14:51That's huge because the link between physical activity and good mental health is clear.
- 14:59And so that really helps kids in terms of not only their school performance,
- 15:03but just their general happiness.
- 15:05Yes. And energy level. Right.
- 15:08What about red flags to look forward to? Yeah, that's, you know,
- 15:13it's tough, you know, because you can't be with your children 24-7.
- 15:16But I think having a good relationship where you have open communication with
- 15:20your kids, especially teenagers, that's important because then they understand
- 15:25that you're on their side in terms of communicating the lack of any benefit
- 15:29in drinking these energy drinks.
- 15:31So in the case of in general, when a child should go to the ER immediately.
- 15:38So some red flag symptoms are, you know, feeling a fast heart rate that just
- 15:43won't go away, even if you're resting.
- 15:45And it's just if kids will tell you, especially older children and adolescents
- 15:49will know if that's an issue.
- 15:51You've tried resting and it just, the heart rate won't budge.
- 15:55That's a sign that you probably need to get to see someone in an urgent care or an emergency room.
- 16:01Because that could be a sustained arrhythmia that's not going away.
- 16:04Significant chest pain that just won't go away even when you're at rest.
- 16:08That's another reason to probably head to the emergency room.
- 16:12That's pretty rare in adolescents or kids.
- 16:15Those are probably the two big red flags. What's the youngest age of child that
- 16:20you've seen who is consuming energy drinks?
- 16:24Sadly, I've had some 11, 10-year-olds who were drinking energy drinks.
- 16:29Wow. In part because they had older siblings.
- 16:32You know, so then it just makes it a little bit easier for them to have access
- 16:35to that. And sometimes the parents weren't aware that that was happening.
- 16:40And what do you say? You know, I try to build a rapport with my patients so
- 16:45that they understand that I'm trying to educate them to be their best self.
- 16:50And usually once they hear that and they understand the correlation with their
- 16:53symptoms, I think they tend to do much better.
- 16:57Moving on to our next topic, anxiety symptoms, but really it's cardiac symptoms.
- 17:03Many parents assume symptoms like a racing heart or feeling suddenly overwhelmed.
- 17:08Those are simple anxiety symptoms, especially in teens.
- 17:12But in some cases, similar symptoms can be a sign of an underlying heart issue.
- 17:18It's difficult sometimes for parents to be able to tell the difference because
- 17:21those symptoms do overlap.
- 17:24If parents and our patient have tried all those other things that we talked
- 17:30about, you know, kids are trying to do the right thing, have a routine,
- 17:33they're sleeping well, they're drinking plenty of water.
- 17:36If those symptoms persist, those are reasons to probably get further evaluation,
- 17:41so that we can try to help them differentiate what's going on.
- 17:45And we can do that with our evaluation and diagnostic testing.
- 17:49And we see many, many patients for those reasons. And thankfully,
- 17:53most of the patients we see in clinic don't have any significant structural
- 17:57or congenital heart disease.
- 17:59Most of the time, it's lifestyle and modifications that they can make to feel better.
- 18:07Lifestyle modifications do you recommend? Is it what you've been saying about
- 18:11getting enough sleep, drinking enough water,
- 18:14eat regular meals, all the things that our mothers and grandparents used to
- 18:18tell us that were important, it still stands true today.
- 18:22You know, you have to, the way you treat your body is the way your body's going to treat you.
- 18:27And so just practical, common sense things.
- 18:32And a lot of times I think it's easy for, especially for teenagers, to forget that.
- 18:36Because the teenage brain thinks that it's invincible.
- 18:40And so we have to help them to remember those things.
- 18:45And pediatricians see so many kids who have anxiety and depression.
- 18:53We're in that epidemic, as we all know.
- 18:58So bottom line, how would you know? What would be a case where you would say,
- 19:02well, this looks more to me like cardiac symptoms that need to be checked out?
- 19:07Yeah, that's a great question.
- 19:09It's difficult to differentiate, but persistence of symptoms,
- 19:13you know, despite trying everything else, and perhaps you've tried therapy or
- 19:18medical management for anxiety, and things just aren't getting better.
- 19:23I think those are reasons to come
- 19:25see us. And many times what we do is put patients and families at ease.
- 19:33We have looked at everything. Your heart looks good. It's functioning fine.
- 19:39And interestingly, a lot of times that's all it takes for patients to feel a
- 19:43little bit better and to kind of get to moving on with the process of healing,
- 19:47when they know that they're actually okay. Mm-hmm.
- 19:53Is it common for a teenager to have a racing heart sometimes?
- 19:57It's not common for teenagers to have racing hearts at rest.
- 20:01With activity, your heart rate obviously increases. It needs to.
- 20:06But it's not a common thing for someone to just be sitting there and to suddenly
- 20:10have a racing heart rate.
- 20:12That's not common. And so if that persists and it's an ongoing issue,
- 20:16then yes, you should get evaluated.
- 20:19And if a child passes out while exerting his or herself, that's a red flag.
- 20:26That's a huge red flag, yes.
- 20:29We call that syncope. When patients pass out, and especially if it happens during
- 20:33activity, that's definitely a reason to go see your pediatrician and potentially your cardiologist.
- 20:40And for pediatricians that's happened to their patient that get in to see the
- 20:45cardiologist as soon as possible or even go to the ER?
- 20:48Absolutely. And our pediatricians in town are great. You know,
- 20:51they understand that that's a huge red flag. Mm-hmm.
- 20:55But passing out where there's a prodrum beforehand, where you're feeling slightly
- 21:02dizzy and then you are weak and then you slowly pass out and you're not exerting
- 21:08yourself, that's not a red flag.
- 21:10Yeah, I mean, it could be, but usually those symptoms are more tied to something
- 21:15that we call vasovagal syncope, where a lot of times patients potentially have
- 21:19not been hydrating enough or eating well before physical activity.
- 21:24And sometimes it's just an autonomic issue with your nervous system.
- 21:28And kids are going through so many changes during puberty, and all of those
- 21:32changes can impact their cardiovascular system, and that can impact their blood
- 21:36pressure, which can then lead to these symptoms that we're talking about.
- 21:40So lots of factors come into play for adolescents.
- 21:45It's so true. And pediatricians have so much, as we know, on their plates,
- 21:49and they may have, this is the 37th patient they're seeing that day.
- 21:55Is there anything that you see that was missed that you want to mention?
- 22:00Most of the time, you can figure out what's going on with a patient with a history
- 22:05and physical and asking the right questions.
- 22:08A lot of that comes with having a good rapport with your patients.
- 22:11But your point is well taken. A lot of times the pediatricians are so busy seeing
- 22:16patients that it's tough to, you know, get that stuff answered in great detail.
- 22:23I have not seen anything in particular that was missed exactly.
- 22:27If anything, I think that, you know, our pediatricians are so aware of these
- 22:31things now that we see so many patients in our cardiology clinic for these issues now.
- 22:36And rightfully so. You know, we've had unique cases, you know,
- 22:40not unlike this cheerleader that you mentioned.
- 22:43And so it's super scary for people.
- 22:45There are several patients who come to my clinic whose parents eventually let
- 22:50me know how many energy drinks they're having. And then we kind of talk about
- 22:53that and realize, oh, maybe this is what was causing my symptoms to begin with.
- 22:58That's not uncommon to see that in clinic. So are you seeing more and more adolescents
- 23:05who are drinking energy drinks?
- 23:07Coffee, energy drinks, all of the above. Yeah, it's much more common now.
- 23:11And it's much more common that
- 23:13they come in with cardiovascular symptoms because of the caffeine intake.
- 23:18It used to be fairly uncommon for us to see that. And it's becoming more and more common now.
- 23:25And kids like to hang out at coffee shops. Yeah.
- 23:30Yes. For hours. This has all been so insightful. I really appreciate you being here.
- 23:36Yeah, I appreciate your time, Holly. Here on Pediatrics Now,
- 23:40I like to promote having a life outside of medicine.
- 23:43What do you like to do, Elaine, to unplug?
- 23:46I'm pretty boring outside of work. You like to walk? I definitely walk a lot. I do too.
- 23:52I live in a neighborhood that's pretty hilly, so it's a great workout.
- 23:55Nice. I love to watch movies and read.
- 23:59Is there a favorite movie you'd like to recommend? I don't generally like to
- 24:03reveal my favorite movie of all time, but I'm going to do it.
- 24:06It's The Goonies. Ooh, it's an old movie. Is that scary?
- 24:09No, I don't think it's scary. Why does it sound scary to me?
- 24:13What is that about? It's about a bunch of kids who go on this adventure and
- 24:17eventually save their family home.
- 24:19Nice. Okay, so it's called The Goonies. And then are you going on any fun trips
