Latest / Cardio Pod: Heart of the Matter / The Role of AI in the Future of Clinical Trials and Therapeutic Development
Transcript
- 0:00Good morning, good afternoon, good evening.
- 0:09I'm Chris O'Connor from the Heart Failure Laboratory and we're here with the Heart of
- 0:14the Matter podcast to discuss our latest think tank meeting in which we took a deep dive
- 0:20into the role of artificial intelligence in augmenting and enhancing clinical trial conduct.
- 0:28And I'm here with our distinguished panel.
- 0:30I'll let them introduce themselves.
- 0:32We'll begin with Dr. Martin Cowley.
- 0:34Hi, Chris.
- 0:35I'm Martin Cowley.
- 0:36I'm a cardiologist and Senior Vice President AstraZeneca in charge of all the late stage
- 0:41trials and cardiovascular.
- 0:43Great pleasure to be here.
- 0:45Thank you, Martin.
- 0:46Dr. Joanne Lindenfeldt.
- 0:47Hi, everyone.
- 0:48I'm Joanne Lindenfeldt, a cardiologist and heart failure physician at Vanderbilt University.
- 0:54Dr. Scott Solomon.
- 0:56Hey, Chris and everyone.
- 0:58I'm Scott Solomon.
- 0:59I'm a cardiologist and clinical trialist at Harvard Medical School in Brigham and Women's
- 1:03Hospital.
- 1:04I guess we're now called Mass General Brigham.
- 1:06Okay.
- 1:07We've got the merger.
- 1:09The Dr. Jonathan Cunningham.
- 1:12Hi, everyone.
- 1:14John Cunningham also from Brigham and Women's Hospital, Harvard Medical School.
- 1:17I'm a heart failure cardiologist.
- 1:19Dr. Mona Fuzon.
- 1:21Hi, everyone.
- 1:22I'm Mona Fuzon.
- 1:23I'm a co-chair of the Heart Failure Collaboratory and a heart failure investigator, a pharmacist
- 1:29by training, and my appointment is at Duke University.
- 1:33And Dr. Mitch Satka.
- 1:34Hi, I'm Mitch Satka.
- 1:36I'm section chief for heart failure and transplant at Innova Heart and Vascular, and then the
- 1:43digital health working group chair for the Heart Failure Collaboratory.
- 1:46Terrific.
- 1:47Well, let's dive right into this.
- 1:49The discussion was fascinating during our think tank, and it really spanned the whole
- 1:54broad spread of clinical trial conduct, patient identification to trial conduct to end points,
- 2:03and then to the dissemination of information.
- 2:07And I'll start with you, Mitch, talk about patient identification.
- 2:13You've been involved in some of the projects using artificial intelligence, which frankly
- 2:19is machine learning, to help with patient identification in a broad health system using
- 2:25the EHR.
- 2:26Could you describe how you think AI might help patient identification in clinical trial
- 2:32conduct?
- 2:33Absolutely.
- 2:34So, we know that a large burden of clinical trial enrollment comes in the form of patient
- 2:42screening, which has been traditionally performed by manual review of patient records, often
- 2:49those coming through a clinic or being seen in an outpatient or inpatient setting, and
- 2:56then performed going through the sometimes very lengthy list of inclusion and exclusion
- 3:01criteria that clinical trials have constructed to enroll the correct patients for their study
- 3:07design.
- 3:08And one of the ways that machine learning or algorithmic input into the electronic health
- 3:15record can assist with this process is by really identifying patients who meet the majority
- 3:21of these inclusion and exclusion criteria prior to manual review, thereby reducing the
- 3:27administrative burden for clinical trial enrollment.
- 3:31And perhaps really adding to patients who would not have been otherwise recognized because
- 3:37they are not being seen in a heart failure clinic or in a cardiology clinic or out in
- 3:42the world in the auspices of the electronic health record, but can be identified and then
- 3:48brought in.
- 3:49And so, there is both this opportunity to find patients who meet the criteria to be
- 3:54included more easily, but also to find patients who will not be otherwise found using the
- 3:59electronic health record and this kind of algorithmic identification of patients.
- 4:05That would be such an advance if we can improve this sort of identification of one patient
- 4:11per site per month that we're left in dealing with now.
- 4:15Martin, give us your broad thinking on as someone who's looking over a number of clinical
- 4:22trials from a sponsor standpoint, how you think AI might improve the ecosystem here?
- 4:29Well, I think there's enormous hope that it will do because it can take out a lot of the
- 4:34very slow tedious work and do it super fast.
- 4:37It never, you know, and it doesn't need a coffee break.
- 4:39It doesn't need a weekend off.
- 4:40It just keeps doing it, which is a huge advantage.
- 4:43So I think from site selection to patient identification and you know, things like protein
- 4:48urine, lots of cardiologists, I'm afraid, don't actually deal with urine.
- 4:53How can you predict from other markers in the medical record that the patient might
- 4:57have protein urine, therefore should be considered for screening at least, for example, and then
- 5:01all the way through to endpoint adjudication, which I know Scott has an interest in also
- 5:08where we've used our huge data sets to show that it's actually very good and easy to train
- 5:13AI to identify cardiovascular mortality from our data sets.
- 5:17And we can now adjudicate events within three minutes of finding them rather than three
- 5:21months from the conventional endpoint process.
- 5:24A little bit more tricky for heart failure, hospitalizations, as we all know, but that
- 5:30we'll learn as well.
- 5:32And I think also final point is that let's make sure that we understand that AI not necessarily
- 5:37just on its own, that it can be a degree of human supervision and AI may do your first
- 5:43best stab at it and then humans can add to that.
- 5:46So it's human plus artificial intelligence needs a faster, more efficient process.
- 5:50So we're very enthusiastic about it.
- 5:52Hopefully not just hype, but actually now translating into meaningful difference.
- 5:56Well, Martin, that's a really good point that there's a lot of fear out there that AI is
- 6:01going to replace everything and there won't be a need for humans.
- 6:05And your point that this is an enhancement, that they're working together, humans and
- 6:11AI machine learning, I think is a really important concept.
- 6:15Well, one of the really strong presentations at the think tank was around the endpoints.
- 6:23And if we quote Norman Stockbridge correctly, he said this may be one of the top priorities
- 6:29to tackle first would be the work that John and Scott have done in this space.
- 6:36Scott, why did you take on the endpoint question of using machine learning and AI?
- 6:44What did you find, Scott and John?
- 6:47I think the short answer is because we were working too many weekends.
- 6:54Though Martin doesn't think we do this on weekends.
- 6:57No, I mean, I think that first of all, as you said, Chris, the use of AI in medicine
- 7:04in general has exploded obviously in the last several years.
- 7:08And we're just starting to think about how we can use them to enhance our clinical trials.
- 7:13And I'm very excited about this as we try to make our trials more efficient.
- 7:19We've been adjudicating endpoints, as you know, for many, many years in clinical trials.
- 7:24I think you and I started on the Valiant trial together about 25 years ago.
- 7:31And we realized that it is enormously time consuming.
- 7:35It also can be even potentially inaccurate in some cases.
- 7:42We've spent a lot of time in the laboratory talking about endpoint definitions and the
- 7:48process of adjudicating endpoints.
- 7:51But we realized that if we can do this faster, we can do this more efficiently, if we can
- 7:56do it with more reproducibility, we can actually make a big difference.
- 8:02And so John had been very interested in this topic and was working to utilize natural language
- 8:11processing to essentially determine endpoints for heart failure in an EMR system.
- 8:21And the main reason for doing that, we don't do that as much in the EMR in individual healthcare
- 8:27systems as we do in trials.
- 8:30In trials, we spend a tremendous amount of time and effort adjudicating.
- 8:35In these large data sets, we mostly use ICD codes and things like that, and we realize
- 8:41there's a lot of information that's available in the medical records, even in the things
- 8:47that we type or dictate that can help determine if a patient has a particular disease.
- 8:53In this case, it's heart failure.
- 8:55So John started there and then moved on to clinical trials.
- 8:59And I'm going to turn to John and let him actually tell us a little bit about what we
- 9:05did.
- 9:06Thanks, Scott.
- 9:07So as Scott mentioned, we started off looking in our own electronic health record.
- 9:12I labeled a bunch of cases myself and we taught the computer to learn whether it was one that
- 9:18I was going to call a heart failure or not based on the 2017 SCTI criteria, the standard
- 9:25clinical trial criteria for heart failure hospitalizations.
- 9:29And then we took that model out of the box into the invested clinical trial and showed
- 9:33that across 157 sites in the US and Canada, the same model also worked well for picking
- 9:41out which hospitalizations would be called heart failure by a clinical events committee
- 9:47in the trial.
- 9:49And I think the excitement here is that we all know that high quality endpoint data is
- 9:55important for getting the right answer in any cardiovascular outcome analysis.
- 10:01And if we can improve the quality of data in our large scale data sets and improve the
- 10:06efficiency of getting high quality data in our adjudicated clinical trials, that's going
- 10:13to allow us to get better information faster for our patients.
- 10:18That's terrific and we know that these CECs are very cumbersome, very expensive.
- 10:25So you're tackling a big part of the core of what many of us are interested in.
- 10:30As I wear my health system hat, I also see an amazing opportunity here, Scott and John,
- 10:37I want you to think innovative of your ideas that as you know, penalties for readmission
- 10:43heart failure, readmissions, the accurate diagnosis of those readmissions is very complex
- 10:49and not well done.
- 10:50We've done adjudication of these readmissions that have gone towards the penalty fees and
- 10:55found that there's a lot of errors there and misclassifications.
- 11:01But then there's also the whole process of the morbidity and mortality committees that
- 11:05go on at every hospital.
- 11:07And in my view, it's asymmetric and there are biases in there and what cases are brought
- 11:14forth and how they're adjudicated.
- 11:17So having these standardized processes that may reduce bias could be very valuable to
- 11:24the health systems also.
- 11:26Well, Joanne, go ahead.
- 11:28I was going to say, I'm not very good at actually assigning ICD codes to my patients when I
- 11:36see them in clinic.
- 11:37I know that I'm just doing whatever I can as quickly as I can to get through to the
- 11:42next patient.
- 11:44This is a way potentially that healthcare systems could use what we write in our notes
- 11:49to do that kind of assignment.
- 11:53And I'm sure some of them are doing this already.
- 11:55And I'll just start with Chris.
- 11:57We got 60% in our analysis.
- 11:59So of the hospitalizations that have a primary code for heart failure, which would be the
- 12:06ones that the penalties would apply to, only 60% of those for us would be SCTI criteria,
- 12:15heart failure hospitalization.
- 12:16So I think there's a lot of cleaning to be done.
- 12:20Very nice.
- 12:21Great point.
- 12:22Joanne, you've served on a lot of data safety monitoring boards and what Martin said was
- 12:28fascinating and that is they can now get the desks identified, classified within minutes
- 12:35as opposed to this long lag time of monitoring the charts and getting them to the DSMC.
- 12:42How do you see AI helping trial conduct from a data safety monitoring committee?
- 12:49Well I think as you've said, we'll get the data much earlier and we'll be able to make
- 12:53decisions.
- 12:54You know, very often endpoints are outstanding.
- 12:55The adjudication has not been done when you meet.
- 12:57I think more than that, I think everything that's been said is exciting.
- 13:01I was excited by this paper and doing adjudicating the endpoints for several reasons.
- 13:05We all know on those committees that we keep a log.
- 13:08Okay, how are we going to decide this when we do it again?
- 13:10How are we going to decide this when we do it again?
- 13:13And it'll be much, much better to have consistency and after the first few trials do it this
- 13:18way then we'll learn if that's exactly the right way or not.
- 13:20So that will be enormously helpful.
- 13:23I mean I see as John said applying this back to our patients and saying, okay that last
- 13:28admission wasn't really our fair admission, you guys goofed.
- 13:32Think about it this way.
- 13:33But more than that there's just when we think about screening for patients there's a huge
- 13:38amount more that could go into this.
- 13:40So the whole thing is somebody has to screen, somebody has to look at value, get the criteria,
- 13:44can automatically correct for weight if you decide to do that.
- 13:47It can notify you who the primary physician is.
- 13:50Potentially if you check on yes screened for the study you could send a note to the primary
- 13:54physician say are you on board with having your patient be this study with a one paragraph
- 13:58or two sentence synopsis of the study and would you be agreeable to having your patient
- 14:02be called and do all of those things that take several phone calls and even to the point
- 14:07of saying your doctor has agreed to let us send you this through your My Health at Vanderbilt
- 14:11or whatever.
- 14:12You know this research study here's something about it click on this if you'd like more
- 14:15information we'd like to speak to you about the study.
- 14:18All of those things could be done in a very rapid period of time and that could really
- 14:23be exciting.
- 14:24I mean we could see how this could save weeks and months of time.
- 14:27So very exciting.
- 14:30Not to mention it could search the chart right when you say why aren't they on guideline
- 14:35directed medical therapy.
- 14:37It could search the chart for why aren't they on spironal lactone.
- 14:40There's probably reasons but sometimes they're buried way back in there and it takes the
- 14:43coordinators hours to find those things.
- 14:46But there's often reasons sometimes there's not but there often are and then you can get
- 14:49that and document it from the source code.
- 14:52So that will even go through the care everywhere the remote things that we get that just are
- 14:57enormously time consuming.
- 14:59So that's really exciting.
- 15:03The same technology that is used for the end point adjudication could be used at the front
- 15:09end for inclusion criteria could be used for adverse event reporting.
- 15:17It's really all different sides of the coin and could make every part of the process more
- 15:23efficient.
- 15:24And do you see a point John and Scott where you could say your patient has a 93% chance
- 15:30of not tolerating Entresto?
- 15:32No seriously.
- 15:35So we don't think you have to go there necessarily.
- 15:38Yeah you just need a label data set of people who had the same input, who had an outcome,
- 15:45who either did or did not tolerate it.
- 15:49Well and even to the point where I think this would help primary caregivers and general
- 15:53cardiologists who don't do it every single day to say all right you can start spiral
- 15:58lactone but you need to check potassium in four days or you need to check potassium in
- 16:02two weeks or just give you those from the criteria we see this is what you need to do
- 16:07and that will be enormously helpful to people like that.
- 16:10That's terrific.
- 16:11You're exactly right.
- 16:12I mean I think that's kind of the 2.0 of AI in our medicine practice right is guiding
- 16:19but-
- 16:20Yeah you have to be slightly careful because you know the concept of a digital twin where
- 16:25you can do trials in silico so let's just say we simulate humans and we do a trial in
- 16:3010 seconds and say well actually this drug would have this effect so let's not bother.
- 16:35I think that looks great on paper and on PowerPoint but actually there's nothing like empiric
- 16:39evidence to show that you don't actually understand this as much as you thought and that the patterns
- 16:45may be spurious.
- 16:46So I think and maybe as a trialist I would argue this that actually doing a trial is
- 16:51an important part of this process but AI can speed up that and get rid of a lot of the
- 16:57slow clunky processes and within my company for example we hope to submit instead of an
- 17:02average of 20 weeks after the database is locked down to three weeks ultimately so that
- 17:09gets science into medicine so much more quickly and actually the data is being used almost
- 17:14immediately to make a difference so for me I think that's more realistic and I feel it's
- 17:19a bit sci-fi all of this let's just simulate humans and see how they get on.
- 17:24Yeah I totally-
- 17:25But maybe I'm a bit on the end of the spectrum.
- 17:27I completely agree with that I don't think we want to skip the trials but I do think
- 17:31as we gain actual trial data with real people with the studies that some of these things
- 17:35will be predictable you know you're not likely to tolerate this and that will be I think
- 17:40valuable for people who do it less for my experience is that for instance general internist
- 17:47to do heart failure if you start spironolactone and you get really hyperkalemic one time that
- 17:51people tend to not do it again so but there are no there's just very rough guidelines
- 17:56in the guidelines for how to do it and what to expect and I think through these trials
- 17:59we're going to be able to get much more precise data for practitioners to be able to do those
- 18:04things and do them safely.
- 18:05Yeah experienced clinicians pattern recognition isn't it and AI is all about pattern recognition
- 18:11so can you make a new medical student actually behave like a 20-year experienced cardiologist
- 18:17probably with an AI tool maybe?
- 18:21I think Martin and Joanne make such important points that you know first of all we have
- 18:28to separate the hype of AI from the reality and the fact is it's just going to get better
- 18:36over the next several years but we have to be very cognizant of what it can do at the
- 18:42moment what we trust it with you know we've all played around with chat GPT we know that
- 18:49it hallucinates on the other hand it's gotten better in the last year I try to stump it
- 18:56all the time I edit a textbook of cardiology and we are incorporating AI chat GPT like
- 19:06interface to be able to query the textbook and get information from the book that hopefully
- 19:14is usable by clinicians so there's that aspect within the clinical trials realm I mean I'm
- 19:22really glad to hear a drug developer saying that they're not going to abandon clinical
- 19:27trials and just do things in silico because I you know we've all heard companies saying
- 19:33they can do this and we have to be very clear and I'm sure Mitch with your FDA hat on you
- 19:40feel this way that's very unlikely it's probably reasonable at the very early stages when you're
- 19:45trying to pick molecules but we don't have enough information to understand for the computers
- 19:51to actually get the biology right and pick out all the things that happen to people when
- 19:57you give them drugs and I just want to follow on what you just said Scott when I tried to
- 20:02write my chapter for your book using chat GPT it hallucinated all of the references
- 20:08that I wanted to use not one of them was a real reference and so just to be clear that
- 20:14really is at the nascent stage of using this technology particularly the productive aspect
- 20:20of this technology when it's being asked to produce something right it sounds very realistic
- 20:26but it typically that is where the technology is not really up to par and but I think the
- 20:32other way to think about it is we've been using predictive models in a lot of ways we've
- 20:36there I think Dr. Connors created a number of predictive models in the history of his
- 20:43manuscript writing and they are used to assign likelihoods of events happening or of things
- 20:51happening I think that those sort of predictive models we are starting to really incorporate
- 20:55more and more into clinical practice and as more data is collected as we've been discussed
- 20:59those predictive models can be more elaborate and perhaps more accurate in helping clinicians
- 21:06to make decisions but really again like Martin was saying not replacing the clinician in
- 21:12the activity but really just assisting them to make the right call at the right time.
- 21:19And if I could jump in you know one of the discussions that we had was around you know
- 21:25the role of the editors as a regulatory body because so much implementation is dependent
- 21:31on what's in the literature and how to you know ensure that the literature is valid you
- 21:39know right now they're at a stage of you know declaring if you use chat GPT but I don't
- 21:45think that's nearly enough and it's very dependent on the authors honesty somebody who's not
- 21:51willing to be honest I think could very easily be putting garbage into the literature and
- 21:57I think that's one of the downsides I don't know how an editor having been on that side
- 22:03of publishing would ever know how to distinguish a real paper from a false one.
- 22:14Well Mona thanks for jumping in on the editorial side the other aspect of this very cumbersome
- 22:21process of getting information out is peer review and could we imagine a world where
- 22:30peer review was doing what John showed us and Scott and that is right now we have we
- 22:37don't have enough adequately trained peer reviewers and we're burning the ones we have
- 22:42out but could we say okay every paper now being reviewed could be reviewed by the AI
- 22:50reviewer and one human reviewer in a hybrid models.
- 22:56What do you think?
- 23:00Well I don't know how to take that I mean I'm not sure we're quite there yet but to
- 23:08bring up this idea of a hybrid model and that's something that John mentioned the other day
- 23:14in his discussion in that you know you rather than just say is going to be all AI it's more
- 23:22like what I would call driver assist I have one of these cars that you can press a button
- 23:27and it'll pretty much steer for you but you've got to keep your hands on the wheel and you've
- 23:32got to be ready to take over and that's the kind of thing that we're thinking about in
- 23:39adjudication processes where you might use AI to help decide for example the cases that
- 23:47are definitely heart failure hospitalization for example or definitely not a heart failure
- 23:54hospitalization but the ones that for which the AI can't make that determination so easily
- 24:00there in the intermediate zone you would have human beings involved but it could still dramatically
- 24:09improve the work.
- 24:13One other question Chris if I may and Martin you may have some thoughts about this about
- 24:19the use potentially of AI in monitoring of clinical trials that's a place where you guys
- 24:25are spending so much money and I imagine this is a way that you could potentially identify
- 24:35fraud for example or identify certainly sloppy investigation I can think of a lot of ways
- 24:42in which AI might be helpful in that respect.
- 24:46I agree Scott and I think you know we're trying to do proportionate monitoring because you
- 24:50can't be a hundred percent intense on everything and I think AI will help us without looking
- 24:54for patterns of bad behavior and poor quality etc and picking that up earlier rather than
- 25:01later but also going back to your point about AI being you know let's say very likely or
- 25:06very unlikely to be something that's fine you can trust it in the middle that's where
- 25:10humans need to add their value to it the FDA seems very open to that and our discussions
- 25:15with them have been very positive very supportive very willing to explore it and say let's go
- 25:22on this journey together see where it takes us.
- 25:25I think other regulators are way behind that and still very fixed on humans being the ultimate
- 25:32judge of everything and that's the gold standard but I think all of us have been on endpoints
- 25:37committees and we know sometimes how much discussion there is about individual cases
- 25:42and I'm not even sure there's a ground truth for some cases it's very difficult in multimorbid
- 25:47elderly patients to know exactly what is going on so it is a balance of probabilities but
- 25:53that kind of mature nuanced attitude I think is quite difficult to communicate with regulators
- 25:58who like certainty so it's an interesting time but I think there's lots of people on
- 26:02this journey not just the trialists and clinicians.
- 26:05Yeah Chris one thing that I'd like to be disabused of this concern about AI that sometimes I
- 26:12don't hear is that as AI takes over the simple things we all do those things now you know
- 26:16we adjust the potassium we look at the but we do all those things so if we get a program
- 26:20that doesn't quite right humans feel comfortable saying wait a minute this doesn't seem quite
- 26:24right to me that is all of us start to have the simple things taken over and we never
- 26:28do them how do we become if you don't know how to do all the little parts of it how do
- 26:34you become the final adjudicator of what you get how do you do the driving when you don't
- 26:39understand you haven't been doing any of the turns or you know putting on your turn signalers
- 26:44I mean that just is the one thing I don't see a solution for I mean when you stop having
- 26:50all that baseline experiences have made you able to say I don't think this probably I'm
- 26:53going to step away from this program I'm not sure we'll be able to do it once there aren't
- 26:57a group of people that have the experience to say this isn't right.
- 27:02Well we've had that experience and that's called a plane crash we know that the pilots
- 27:07who haven't had the training on the manual adjustments of the instrument board they're
- 27:13relying on the completely on the electronics have stuttered or failed in their ability
- 27:18to compensate so you bring up a really good point I was going to go around the table and
- 27:22just in our conclusion and I'll count that as your concern but give us your top concern
- 27:32about AI in medicine and Joanne you so nicely articulated one but I'll go around the table
- 27:40here Mona.
- 27:41Misinformation one word misinformation.
- 27:46Okay one word Mitch.
- 27:50Well I'm going to follow in Mona's footsteps because I do think and going with Dr. Kalit
- 27:55that misinformation is one of the greatest challenges to the data that we create and
- 28:02utilizing it appropriately and knowing what is real and what is fake for not only the
- 28:07clinical trials but all the population.
- 28:10John I think portability I think we always have to worry that we trained in one area
- 28:16and then we're evaluating in a different time in a different place and that you know if
- 28:21it was a human doing the review then they would say wow this these documents really
- 28:26look different or something's wrong but the other computer just sort of flows forward
- 28:30and gives an answer anyway so we want to keep checking that keep our eyes on the data and
- 28:37keep making sure that you know the computer saying the right thing.
- 28:42Martin I think let's just make sure we're not just copying human biases you know you
- 28:50can use AI to train an interview panel to come up with exactly the same biases as the
- 28:54humans very predictably that's not what it's about it's supposed to be adding value not
- 28:59just simulating it so yeah let's just think about the use cases and what we're trying
- 29:04to achieve and as I said earlier AI plus human intelligence is what we're looking for.
- 29:10I love it I love it Scott and I worry about overhype and I think we have to figure out
- 29:18what AI can do for us at the moment we have to recognize that it's going to change dramatically
- 29:25very fast very different from drugs which take maybe 10 years to really change but the
- 29:33AI will change in months and we're going to update the algorithms very quickly so we have
- 29:40to be cognizant of that and adapt how we work based on how the AI changes.
- 29:48Ultimately I think it will be a good thing if we keep our hands on the wheel.
- 29:54Really well said and I agree with Martin that the biases could actually enhance disparities
- 30:02and care not reduce them so that's really my fear that the data sets that we have may
- 30:08not be robust enough to help us reduce disparities so a terrific conversation today gosh you're
- 30:15so shy and had no energy at you know four o'clock in the afternoon but wow AI is going
- 30:24to be with us it's going to be with us in medicine it's going to be with us in clinical
- 30:27trial development and I really appreciate your comments today and we're going to have
- 30:32more of this I guarantee you that Heart Failure Collaboratory will be taking this on strongly
- 30:36so thank you for being here with Heart of the Matter podcast have a great day.
