Your hsCRP comes back in the “normal” range. Does that mean inflammation isn't contributing to your cardiovascular risk?
For people with type 2 diabetes, the answer may be more complicated. In this episode of The Health Pulse, we explore emerging evidence connecting interleukin-6 (IL-6), insulin resistance, and heart failure—and why one of the most commonly measured inflammation markers, hsCRP, may not always capture the full story.
We begin with the cardiorenal-metabolic connection. Type 2 diabetes doesn't affect glucose in isolation. Insulin resistance, vascular dysfunction, kidney disease, sodium retention, visceral adiposity, and chronic inflammation can interact to increase pressure and volume stress on the heart. Over time, these disturbances can contribute to cardiac remodeling and conditions such as heart failure with preserved ejection fraction (HFpEF).
Then we compare two biomarkers that are often discussed as though they measure the same thing: IL-6 and high-sensitivity C-reactive protein (hsCRP).
IL-6 is an upstream signaling cytokine produced by multiple tissues and immune cells, including dysfunctional adipose tissue in chronic metabolic disease. CRP sits farther downstream: inflammatory signaling, including IL-6, stimulates the liver to produce it. That distinction may matter when trying to understand the biological processes driving risk rather than simply detecting a generalized inflammatory response.
We examine findings from an analysis connected with the long-running Look AHEAD trial, where IL-6 showed a stronger relationship with incident heart failure than hsCRP in adults with type 2 diabetes. The findings raise an important question: could upstream inflammatory signaling reveal cardiometabolic risk that a conventional downstream marker sometimes misses?
There is also a more hopeful side to the story. Lifestyle intervention can influence inflammatory biology. Improvements in physical activity, body composition, metabolic health, and visceral adiposity can reduce chronic inflammatory signaling, including IL-6.
But IL-6 comes with an important paradox. During exercise, contracting skeletal muscle can temporarily release large amounts of IL-6 as a myokine involved in fuel mobilization and adaptation. That short-lived physiological pulse is very different from persistently elevated IL-6 associated with dysfunctional adipose tissue and chronic immune activation. Context matters.
We also explain why IL-6 isn't ready to become a simple standalone screening test. Levels can vary with infection, exercise, timing, inflammatory disease, and other factors, and routine clinical interpretation remains less standardized than established cardiovascular biomarkers.
Instead, we zoom out to the broader cardiometabolic picture. Depending on the individual, markers such as HbA1c, fasting insulin, ApoB, eGFR, urine albumin-to-creatinine ratio, and BNP or NT-proBNP can help evaluate different components of metabolic, kidney, vascular, and cardiac risk.
The lesson isn't to replace hsCRP with IL-6. It's to recognize that inflammation is a network, not a single number—and a reassuring laboratory result should always be interpreted within the larger metabolic picture.

Welcome And The Big Question
NicoletteWelcome to the Health Pulse, your go-to source for quick, actionable insights on health, wellness, and diagnostics. Whether you're looking to optimize your well-being or stay informed about the latest in-medical testing, we've got you covered. Join us as we break down key health topics in just minutes. Let's dive in.
RachelYou know, usually when you go to the doctor for uh just a standard checkup, there's this comforting expectation of certainty.
MarkRight. You want that clear answer.
RachelYeah, exactly. You sit on that crinkly paper, they draw your blood, and a few days later you get a report. And the numbers are, you know, either in the green zone or the red zone.
MarkIt feels very binary.
RachelIt really does. Like if your inflammation marker, specifically that standard one your doctor always orders, HSCRP, if that's in the green, you naturally breathe a sigh of relief. You think, great, my heart is safe, everything is fine.
MarkLike a definitive green light to just keep doing whatever you're doing.
RachelBut then you step into the complex world of metabolic health and cardiology, and suddenly you realize that green light might actually be masking a really hidden hazard. So welcome to today's deep dive.
MarkGlad to be here.
RachelWe are so thrilled to have you, the listener, here with us as we explore this truly fascinating article from Quick Lab Mobile, which was just published in September 2026.
MarkYeah, and it's a big one.
RachelIt is. They analyzed a major new study out of the journal JCC Heart Failure, which looked at data from a massive long-term clinical trial called Look Ahead.
MarkAnd this specific study, I mean, it really forces us to completely reevaluate what those standard trusted lab tests are actually telling us about our bodies.
RachelExactly. So the core question driving our entire deep dive today is this could the standard inflammation test your doctor relies on, that HSCRP test, be totally missing a hidden heart failure risk, especially if you happen to have type 2 diabetes. Okay, let's unpack this.
MarkAaron Powell And as we do, it's really crucial to understand that this isn't just about, you know, swapping out one blood test for another in your annual physical.
RachelRight, it's bigger than that.
MarkWay bigger. We're talking about fundamentally changing how we visualize the heart's health. We are moving away from looking at the heart as just mechanical pump and starting to look at the illuminated biological pathways. Trevor Burrus, Jr.
RachelLike a complex chemistry lab.
MarkExactly. A chemistry lab that is just constantly running inside your cardiovascular system.
RachelI love that visualization. But before we start, you know, throwing around acronyms and talking about biomarkers, we really need to understand the battlefield itself. Aaron Powell Right.
MarkThe root cause.
RachelYeah. We need to know why the heart is at risk in the first place when someone has type 2 diabetes. Because when most of us hear heart failure, we immediately picture a massive heart attack.
MarkThe classic Hollywood chest clutching scene.
RachelExactly. We picture severely blocked arteries like plumbing that just gets clogged up with grease until it bursts.
How Diabetes Breaks The Heart
RachelBut how does diabetes essentially break the heart without ever actually clogging a major pipe?
MarkAaron Powell Well, rethinking that plumbing analogy is step one. Because type 2 diabetes drives heart failure entirely independently of heart attacks.
RachelSo it's a completely different mechanism.
MarkIt is. It's a slow systemic erosion caused by a combination of things. You've got insulin resistance, elevated blood pressure, abdominal obesity, and kidney dysfunction.
RachelWow. So a lot of moving parts.
MarkYeah. And all of these combine into something we call the cardiorenal cycle.
RachelOkay, let's pause right there because that term, the cardiorenal cycle, that sounds like a loop you really do not want to be caught in.
MarkYou definitely don't.
RachelHow does that actually work mechanically?
MarkIt's essentially the heart and the kidneys trapping each other in a downward spiral.
RachelOh wow.
MarkYeah. So when the heart starts pumping a little less efficiently, just due to metabolic stress, the kidneys receive less blood flow.
RachelOkay. Makes sense.
MarkAnd the kidneys, they interpret this low flow as dehydration or a drop in overall blood volume. So they panic.
RachelThey think you're bleeding out or something.
MarkRight. They release hormones that tell the body to retain salt and water to boost the pressure back up.
RachelAaron Ross Powell, which means the actual blood volume increases, right. Making the whole cardiovascular system run at a much higher pressure.
MarkExactly. And now that already struggling heart has to push against even more pressure and it has to pump a heavier, larger volume of fluid.
RachelAaron Powell So it's working overtime.
MarkYes. And that extra strain damages the heart muscle further, which reduces blood flow to the kidneys even more.
RachelAaron Ross Powell, which makes the kidneys retain even more water.
MarkTrevor Burrus Bingo. They are locked in this feedback loop of just increasing stress.
RachelAaron Powell So it's not a localized plumbing problem at all. It's a systemic pressure and volume crisis.
MarkAaron Powell That is half the battle, yeah.
RachelYeah.
MarkBut to understand the rest of the mechanism, you have to look at the heart's internal metabolic engine.
RachelAaron Powell Okay, the chemistry lab you mentioned earlier.
MarkAaron Powell Right. A healthy, normal heart is incredibly flexible, depending on what you are doing, whether you're sleeping, sprinting, fasting, it can seamlessly switch its fuel source.
RachelAaron Powell Like it just adapts on the fly.
MarkAaron Powell Yeah. It burns fatty acids, it burns glucose, it can use lactate, and it uses ketones. It adapts to whatever energy is most efficiently available at that exact moment.
RachelAaron Powell So it's sort of like a perfectly tuned hybrid car switching between gas and electric depending on the terrain.
MarkAaron Powell That is a very apt way to look at it, actually. But when you introduce insulin resistance into the system, that flexibility is just completely destroyed.
RachelBecause insulin is the key that lets glucose into the cells, right?
MarkAaron Ross Powell Exactly. Insulin resistance essentially blocks a heart's ability to take up and use glucose efficiently. And because the heart is a muscle that never ever stops beating, it desperately needs fuel to survive.
RachelIt can't just take a break.
MarkRight. So it ends up abandoning glucose and essentially drowning in circulating fatty acids.
RachelAaron Powell And I'm guessing forcing the engine to run on just one type of fuel in massive quantities probably isn't a good thing.
MarkNo, it's terrible. It creates a highly toxic environment. When the supply of fatty acids exceeds the heart's capacity to safely burn or store them, it generates a massive amount of oxidative stress.
RachelWhich is essentially rusting from the inside out.
MarkYeah, and the mitochondria, those microscopic powerhouses inside the heart cells, they start to sputter and dysfunction.
RachelUh-oh.
MarkAnd this toxic environment signals the body to start laying down fibrous tissue. The heart muscle physically changes its composition.
RachelAaron Powell So it's structural damage now.
MarkYes. It develops what is known clinically as HFPEF. That's heart failure with preserved ejection fraction.
RachelOkay, let me make sure I have this right. The heart is still technically pumping blood out, which is why the ejection fraction is, quote, preserved, but the muscle itself has become too stiff to relax and fill properly between beats.
MarkAaron Powell That is the exact mechanism, yes. It becomes a stiff, rigid engine rather than a supple, flexible pump. Wow. And the primary driver behind this structural stiffening, this fibrous buildup is chronic inflammation.
RachelAaron Powell Which brings us perfectly to how we actually measure that inflammation in a clinical setting. Because if the heart is getting stiff and fibrous because of an inflammatory fire, we need a reliable smoke detector.
MarkWe really do.
RachelAnd the Quick Lab Mobile article
The Cardiorenal Spiral Explained
Racheldetails two main actors in this drama, IL-6 and HSCRP.
MarkYes. IL6 stands for innerleukin 6 and HSCRP stands for high sensitivity C reactive protein. Okay. They're both related to inflammation, but they sit at completely different points in the biological cascade. They tell you fundamentally different things.
RachelSo let's break down those positions. Because the JCC study describes IL-6 as an upstream cytokine. And for anyone listening who isn't steeped in immunology, a cytokine is basically just a signaling protein, right?
MarkYeah, it's a messenger.
RachelOkay. So it gets released directly by dysfunctional fat tissue, activated immune cells, and vascular tissue. Meanwhile, HS-DAS CRP is an acute phase protein. It is produced downstream by the liver, but only after the liver receives the signal from markers like IL-6.
MarkExactly. It's a reaction to the initial signal.
RachelOkay, so if I'm visualizing this, IL-6 is like the specific neighborhood fire alarm going off right where the actual smoke is. While HSCRP is the citywide siren that the mayor, which is the liver here, turns on downstream. Like that. The siren tells you there's an emergency somewhere in the city, but the local alarm tells you exactly where the fire started.
MarkAaron Powell That analogy tracks perfectly, actually. What's fascinating here is how this plays out in the specific context of obesity and insulin resistance.
RachelHow so?
MarkWell, historically, the medical community thought of adipose tissue body fat as just a passive storage unit for extra calories, like a biological closet.
RachelSitting there doing nothing.
MarkRight. But we now know that dysfunctional visceral fat is actually a highly active endocrine organ.
RachelWait, how does fat become dysfunctional? What is actually happening inside that tissue?
MarkSo when a person has excess visceral fat, and that's the fat wrapped around the incernal organs, those fat cells become engorged with triglycerides. They physically swell up.
RachelOkay.
MarkAnd eventually they actually outgrow their own blood supply.
RachelWow, they get that big.
MarkYeah, and the tissue becomes hypoxic, which means it is literally suffocating from a lack of oxygen.
RachelThat sounds awful.
MarkIt is. The fat cells start to die, which causes the immune system to send in macrophages, these are cleanup cells, to deal with the mess. And both the suffocating fat cells and those immune cells start actively secreting IL-6 into the bloodstream.
RachelSo the fat itself is actively pulling the neighborhood fire alarm because it's suffocating.
MarkContinuously. It secretes IL-6, which drives this systemic cascade of inflammation. That IL-6 travels through the bloodstream to the liver. And the liver responds to that alarm by turning out CRP.
RachelI see the chain reaction now.
MarkRight. And because of this sequence, neither marker is a complete measure of inflammation on its own. They are just telling you about different stages of the exact same disastrous event.
RachelOkay, so if IL-6 is this hyperspecific alarm going off right in the fat cells, the immediate question is, well, what happens when you actually test these two markers against each other in the real world?
MarkAaron Powell That is the million-dollar question.
RachelAaron Powell And this is where the JCC heart failure analysis of the look-ahead trial comes into play, right? Because this was a massive randomized study of adults with type 2 diabetes who are also overweight and obese.
MarkAaron Powell It was. And the scale and the duration of the data are what make these findings so incredibly robust.
RachelYeah, give us the numbers on that.
MarkSo the researchers had baseline HSCRP measurements for 1,902 participants, and they had baseline IL6 measurements for 1,507 participants.
RachelThat's a lot of people.
MarkIt is. And the median HSCRP was 4.04 milligrams per liter, while the median IL6 was 2.07 picograms per milliliter. They then followed these individuals for roughly 12 years. 12 years, wow. Yeah, they wanted to see who developed heart failure or suffered from atherosclerotic cardiovascular disease over that long time frame.
RachelAaron Powell Okay, wait, let me push back on this premise for a second. If HSCRP
IL-6 Versus HSCRP Biology
Rachelis the citywide siren, shouldn't it be just this loud if a major heart failure event is coming down the pipeline? I mean, the siren is supposed to warn us. Why did the study find it totally missed the signal?
MarkWell, the researchers adjusted for all the traditional cardiovascular risk factors you would expect, right? Age, demographics, blood pressure, even statin use.
RachelSure, standard procedure.
MarkAnd after running those adjustments, they found that HSCRP was not independently associated with incident heart failure in this population. It missed the signal entirely.
RachelThat is crazy. But IL-6 caught it?
MarkIL-6 caught it beautifully. Across the overall cohort, every time the log transformed IL-6 increased by one standard deviation, the risk of developing heart failure jumped by 43%.
RachelWow, that is a massive jump for a single standard deviation.
MarkThe data actually gets even more pronounced. For the participants who had no prior history of cardiovascular disease at the start of the study, that same one standard deviation increase in IL-6 meant a staggering 92% higher risk of incident heart failure.
RachelAlmost double the risk.
MarkYes.
RachelBut let's go back to the mechanics of this. Why did the citywide siren fail so badly while the neighborhood alarm worked perfectly?
MarkIt really comes down to a concept called metabolic noise. Okay, metabolic noise. Being back to that median HSCRP of 4.04 we mentioned, clinically speaking, that is already quite elevated.
RachelAaron Powell Because anything over three is usually considered high risk, right?
MarkExactly. And because this entire study population consisted of people with type 2 diabetes and excess weight, virtually everyone had a high baseline of general inflammation. So the HSCRP was elevated across the board, just reflecting a broad, generalized metabolic distress.
RachelAaron Powell Okay, so if every single neighborhood in the city has a minor fire burning, the citywide siren is just blaring constantly. It completely loses its ability to tell you which specific neighborhood is about to burn to the ground.
MarkThat is the exact problem with downstream markers in a highly inflamed population. It just becomes background noise.
RachelBut IL-6 didn't get drowned out.
MarkNo, because IL-6 was able to isolate the specific signaling pathways. It caught the direct communication from that suffocating visceral fat and those activated immune cells, which were actively driving the fibrous damage and stiffening of the heart muscle.
RachelSo it cut right through the noise.
MarkExactly. Because it is the actual molecule causing the damage at the cellular level.
RachelIncredible. Okay, so if IL6 is this hyperspecific alarm going off in the fat cells, predicting a daunting 92% higher risk, the immediate question for anyone listening is well, can we actually turn that alarm off or are we just stuck with it?
MarkRight, or are we doomed?
RachelYeah. Which leads us directly to the intervention arm of the look-ahead trial.
MarkYes, because this wasn't just an observational study where researchers just sat back and watched people get sick. It was originally designed to test an intensive lifestyle intervention against standard care.
RachelAnd the word intensive is doing a lot of heavy lifting here. This wasn't a doctor just handing over a generic pamphlet that says, eat less, move more on your way out the door. No, not at all. This was a highly structured one-year program. It involved serious calorie reduction, aiming for 175 minutes of moderate physical activity per week, frequent behavioral support sessions, and even utilizing meal replacements to ensure those targets were actually hit.
MarkIt was very rigorous, and the physical results were dramatic. After one year, the intensive intervention group achieved an 8.6% body weight loss.
RachelCompared to what in the standard group?
MarkCompared to less than 1% in the standard diabetes education control group.
RachelWow. But the real mic drop moment in the data is what happened to the actual inflammation markers. That intensive lifestyle group saw a massive 28.7% drop in IL-6.
MarkWhich is huge. The standard education group only saw an 11.8% decline.
RachelThat's a massive difference.
MarkA highly statistically significant difference, yeah. It proves that a high IL-6 level isn't some fixed genetic destiny. It is highly modifiable based on how we live, how we eat, and how we move. By shrinking that fact. Exactly. By shrinking that dysfunctional visceral adipose tissue, you relieve the hypoxia. The fat cells stop suffocating, the immune cells retreat, and you physically remove the source of the chronic IL-6 signaling.
RachelHere's where it gets really interesting, though, because reading through the analysis of
Look AHEAD Results And Metabolic Noise
Rachelthe study, there is a glaring biological paradox that we need to address.
MarkOh, the exercise paradox.
RachelYeah. Because we've established that IL-6 is this dangerous upstream signal causing fibrous heart failure. But the clinical literature explicitly says that our skeletal muscles actually release IL-6 when we exercise. They do. So if IL-6 is the bad guy, aren't we just flooding our bodies with the exact molecule causing heart failure every time we hit the treadmill for those 175 minutes?
MarkIt is one of the most fascinating paradoxes in human biology, honestly. How can the exact same molecule be both a poison and a cure?
RachelRight. How does that work?
MarkIt all comes down to duration and source. When you exercise, your contracting skeletal muscles release IL-6. But in this context, it acts as a myokine, which is a specialized messenger derived from muscle tissue. Okay, a myocine. And this exercise-induced spike is very, very short-lived. It helps coordinate energy during the workout, basically signaling the body to pull in more glucose.
RachelSo it's an acute signal.
MarkYes.
RachelYeah.
MarkAnd crucially, once the workout is over, that sharp spike of IL-6 triggers a massive cascade of anti-inflammatory effects to help the muscle repair.
RachelOh wow. So a quick, intense burst from the muscles is actually initiating a healing process.
MarkAaron Ross Powell Biologically, it is an entirely different event than the chronic, relentless trickle of IL-6 leaking out of suffocating visceral fat, you know, 24 hours a day, seven days a week.
RachelThat makes so much sense.
MarkThe muscle spike is a targeted signal for acute adaptation and repair. The fat trickle is just a chaotic signal of constant low-grade tissue distress.
RachelAaron Powell So the dose and the duration make the poison.
MarkThat makes total sense. So having established that IL-6 is a vastly superior predictor for heart failure in this demographic and that it responds beautifully to targeted lifestyle changes.
RachelWhich is great news. It is. But if I'm listening to this deep dive, I'm probably thinking, forget HSCRP, it's just metabolic noise. I need to call my doctor and demand an IL-6 test tomorrow morning.
MarkRight. That's the natural conclusion.
RachelAaron Powell But why might that actually be a bad idea for the average patient right now?
MarkAaron Ross Powell Well, if we connect this to the bigger picture, we really have to acknowledge a frustrating reality of modern medicine, which is that a research breakthrough doesn't instantly translate into a routine clinical screening tool.
RachelIt takes time.
MarkIt takes a lot of time. IL6 testing has significant limitations in the standard doctor's office today. First off, it lacks a universally accepted clinical threshold.
RachelSo there's no clear red zone.
MarkExactly. We know higher is generally worse, but we don't have a standardized cutoff number across all labs where a doctor can point and say, aha, you have crossed into the danger zone.
RachelAnd it also fluctuates wildly day-to-day, right?
MarkYeah, incredibly wildly. You could have a single, terrifyingly high IL-6 score on a Tuesday simply because you are fighting off a mild viral infection, or as we just discussed, because you just finished a really hard resistance training workout.
RachelSo it could just be a false alarm.
MarkAbsolutely. And furthermore, there is no targeted FDA-approved treatment protocol that says if IL6 is X, prescribe drug Y to prevent heart failure.
RachelAaron Powell Which explains why the medical establishment is still relying on other more established markers. I mean the guidelines definitely reflect this.
MarkThey do.
RachelThe 2025 American College of Cardiology scientific statement still explicitly prefers HSCRP for assessing atherosclerotic risk, you know, the risk of plaque buildup and traditional heart attacks.
MarkAaron Powell Because HSCRP is highly standardized across all commercial labs, it is very inexpensive to run. And most importantly, we have decades of clinical data on exactly how to treat it. If your HSCRP is high, doctors know how to adjust statins or other therapies.
Lifestyle Change And The Exercise Paradox
MarkAnd if a doctor is specifically worried about heart failure, the 2026 American Diabetes Associates Standards of Care recommend testing for BMP or NT Pro BMP.
RachelOkay, let's break those down because they sound like just more alphabet soup. What are BNP and NT pro BNP?
MarkSo those are naturatic peptides. And unlike IL6 or HSCRP, which measure inflammation, BNP is released when the physical walls of the heart experience increased mechanical stress or stretch. Okay. So going back to our earlier engine analogy, it is a direct indicator that the heart pump is physically struggling with fluid volume and pressure right now. It basically tells you the engine block is actively cracking under the strain.
RachelSo ordering more biomarkers just for the sake of having more data isn't automatically better medicine. I mean, a random IL6 test right now might just confuse you and your doctor if it's taken totally out of context.
MarkIt absolutely does not replace established holistic testing. If you want a clear picture of your cardiometabolic risk today, you really need to look at the whole system.
RachelSince we have the time, let's actually tie those standard tests back to our analogies. When doctors check your HPA1C and fasting insulin, they are basically checking the fuel lines, right? Seeing how much sugar is gunking up the system and how hard the body is working to push it into the cells.
MarkCorrect. That measures the baseline insulin resistance that kicks off the whole problem. Then you look at APOB, which is counting the actual cholesterol particles in the blood.
RachelWhich are the garbage trucks that can crash and clog the plumbing.
MarkYes, exactly. And you must look at kidney markers like EGFR and urine albumin. EDFR essentially measures the flow rate and the filtration efficiency of your body's water treatment plant.
RachelBecause, as we discussed with that cardiorenal cycle, if the water treatment plant slows down, the pressure backs up and damages the heart pump.
MarkRight. It's all connected.
RachelSo it's about painting a complete picture of the metabolic environment rather than obsessing over a single inflammatory pixel.
MarkYes. IL6 is an incredibly promising research tool. It definitively proves that heart failure and diabetes has a distinct, measurable inflammatory fingerprint. Yeah. But clinically, you still manage that risk by addressing the foundation.
RachelBy repairing the fuel lines, clearing the plumbing, supporting the kidneys, and reducing the physical wall stress on the heart itself.
MarkExactly.
RachelOkay, let's unpack this. So, what does this all mean? We've covered a lot of complex cellular biology today, but the core journey for you listening is actually quite clear. We learned that heart failure in type 2 diabetes isn't just about blocked pipes causing a sudden heart attack. It's about a slow burning inflammatory fire that creates a stiff, rigid engine. Right.
Why IL-6 Testing Is Not Routine
RachelAnd we learned that while your standard HS CRP test is a great downstream indicator for general cardiovascular risk, the upstream IL-6 marker shows us that the type and the source of the inflammation matter immensely.
MarkAnd I think the most empowering takeaway for you should be that your risk is not defined by a single lab number. The goal of reading a study like Look Ahead isn't to start chasing a low IL-6 score on a lab requisition form. The goal is to understand that the root causes of that chronic inflammation, the suffocating visceral fat, the insulin resistance, forcing the heart to burn toxic fuel and physical inactivity, they are entirely within your power to modify.
RachelI mean, the 28.7% drop in IL-6 from the lifestyle intervention arm proves that your daily choices are speaking directly to your cells. You are constantly altering that inflammatory signaling based on how you move and what you eat.
MarkIt is such a great reminder that the human body is deeply dynamic. By changing the environment through nutrition, through that 175 minutes of exercise, you fundamentally change the signals being sent to the heart muscle.
RachelBeautifully said. And as we wrap up this deep dive, I really want to leave you with one final thought to ponder. We talked early on about how insulin resistance forces the heart to abandon its preferred flexible fuel sources like glucose and instead frantically burn fatty acids until its mitochondria literally fail.
MarkRight. The metabolic engine gets flooded with the wrong fuel entirely.
RachelExactly. So if our hearts can literally change their entire internal chemistry and structural composition based on the specific fuel we force them to burn, maybe the ultimate heart disease test of the future won't just measure the downstream smoke.
MarkOr even the upstream alarm of our inflammation.
RachelRight. Maybe the true diagnostic holy grail will be a real-time measurement of the exact fuel mixture our heart is being forced to consume at any given moment. Just something to think about the next time you are looking down at your lab results, wondering what is really happening under the hood.
MarkThat is a fascinating perspective on where the science needs to go next.
