Are Heart Meds Forever?

/in /by

The prevailing thought on pharmacological treatment of cardiovascular disease (CVD) is that once you’re on a class of medications, you’re on them for life—new meds may be developed to replace some, but treatment continues forever. That contributes to the conspiracies about big pharma and the greed of the medical community. I’m not going to say that never happens, but maybe a recent study can reveal a ray of hope.

Beta-Blocker Study

Researchers selected a very specific group of potential subjects from three countries. The subjects must have had a myocardial infarction (MI), also known as a heart attack; they must have had both angiography and an echocardiogram; they must have an ejection fraction equal to 50% or more; and they were tracked for 3.5 years.

This is the important part: On a randomized basis, half were given the typical treatment of beta-blockers while the other half were not. There were two intermediate analyses of the data to make sure the non-beta blocker group were not at greater risk for problems such as another MI, or worse yet, death.

The analyses demonstrated that there were no differences in outcomes related to any CVD condition between the groups. In other words, the beta-blocker did not provide any additional benefit. There are more trials underway to confirm these results, but we now have a first step on the path to determining whether medications are necessary for life or not.

The Bottom Line

Let me be clear: Do not stop any medication without discussing it with your physician! All physicians were aware that their patients were in the trial and who was and was not on beta-blockers. Also, the standard for ejection fractions (amount of blood pumped per beat) was relatively high. But it illustrates this point: Every visit to your physician or specialist should include a thorough discussion of your medications and whether you need to remain on each one.

There’s also another part to all this: What are you willing to do to help eliminate the need for the medication? Diet, exercise, reducing body weight? What will you do if it will help? In other words:

Is It Worth It?

/in /by

At an obesity conference, the report on the clinical trials for a pre-diabetes and diabetes medication left the crowd on their feet and cheering. There are reports of well-known personalities who’ve used the drug with great results. But the ultimate question about a pharmaceutical approach to obesity has to be this: is it worth the money? Let’s start by looking at the pharmaceutical and then the return on investment.

How It Works

The body makes proteins called incretins which can stimulate the release of insulin. One incretin hormone, GLP-1 (glucagon-like peptide-1), is manufactured in the upper digestive system in response to carbohydrate intake. In subjects with type 2 diabetes, this hormone effect is diminished or no longer present.

The ability to stimulate the production of insulin and prevent the release of glucose by glucagon can be stimulated pharmacologically by semaglutide, a receptor agonist—that means it turns on the glucagon. In subjects with type 2 diabetes, semaglutide stimulates GLP-1 receptors significantly, thereby reducing blood glucose and improving glycemic control. In addition, it has multiple effects on various organ systems; most relevant are a reduction in appetite and food intake, leading to weight loss in the long term. Since GLP-1 secretion from the gut seems to be impaired in obese subjects, it was logical to test it in obese populations. Those were the study results I reported on Tuesday.

All in all, this sounds like it might be a potential solution to our obesity crisis, but there are some unanswered questions. What is the long-term safety of regular use of the drug? How does the microbiome impact the effectiveness of the drug? But more than that, everything comes with a price, which begs the question: is it worth it?

The Price

The price of using semaglutide for obesity is really two-fold. First is the actual cost of the weekly injections which is about $1,400 per month at retail. If your insurance will cover it, I’ve seen prices as low as $25 per month. We know that people lost an average of 18% of their starting weight at 68 weeks—the length of the longest study to date—but the rate of weight loss declined near the end of the study. How long will insurance cover it beyond that, and will a person continue to lose weight? We don’t know.

After using the drug for 20 weeks, the placebo group was switched to a placebo and immediately began to gain weight. By the end of 68 weeks, they had regained all but 5% and were still gaining. Would an investment of close to $17,000 to lose about 20% of your weight be worth it if you began to gain it back? There are many questions around whether people can take this drug for the rest of their lives; every pharmaceutical intervention must have an end strategy. The researchers did not address the issue.

The Bottom Line

The research into this pharmaceutical intervention was well done. However, unless the intervention includes an exit strategy, it could be a waste of money. Perhaps a lower carbohydrate diet may be a partial solution because this drug impacts carbohydrate metabolism. But we don’t know whether the weight loss would be enough to have the body take over and do the same thing on GP-1 by itself.

I think this shows a hopeful approach and it may turn out to be a boost to someone who is absolutely willing to change their lifestyle or someone who needs to lose weight for a specific purpose, such as joint replacement surgery or preparing for IVF. But for most of us, maybe it’s better to save the time and money and do what we know works: Eat less. Eat better. Move more.

Happy New Year!

/in /by

It’s good to be back talking to all of you again. The New Year is a time of optimism, everything seems possible, and there’s an enthusiasm for achieving health goals. One thing many people want to do is to lose some weight. It seems appropriate to cover a couple of drugs that were recently approved by the FDA to treat obesity. They’re a pharmaceutical approach to weight loss, and they’ve gotten so much press I have to cover them.

You’ve probably seen the commercials for a pre-diabetes and diabetes medication called Ozempic. It also has a sister drug called Wegovy that was approved for use in teens. In at least two clinical trials, subjects who had weekly injections of the drug lost at least 15% or more of their body weight in 68 weeks. Those who were switched to placebo injections started to gain back the weight they lost. All subjects were supported with monthly consultations with dieticians to induce a 500-calorie reduction in food intake and to increase exercise levels. Markers for type 2 diabetes improved such as HbA1c and blood glucose.

Is this the be-all and end-all to the obesity epidemic? And exactly how does this drug work? I’ll cover that on Saturday.

The Secret to Prevention

/in /by

Consistency.

I thought I’d lead with the secret to disease prevention instead of making you wait. Whatever you want to accomplish in taking charge of your health, you have to be consistent. The polypill study proved it although the scientists, being conservative in their conclusions, don’t come out and say it—but I will. Here’s why.

Why the Polypill Was the Difference

The subjects taking the polypill were more consistent in taking their medications than the subjects who took the exact same medications as individual pills. They didn’t ask the subjects whether it was easier to remember to take one versus three pills; that could be a factor as the mean age of the subjects was over 75. It’s also easier to keep one medication refilled rather than three. Whatever the reason, the subjects just took their medication on a more regular basis and thus saw a decrease in recurrence of cardiovascular disease events.

While this was a study about medication, it applies to reducing or changing your foods to eat healthier, reducing the risk of cardiovascular disease and diabetes, or any other health goal: we have to be consistent. Even getting a health benefit from taking a supplement requires you to take it regularly for weeks or months to see a benefit.

Weight Loss: A Special Case

Losing weight and maintaining the weight loss is the single most difficult thing humans can do. I know. I’ve been trying for decades. I don’t weigh what I used to weigh, but I’m not where I want to be. I know many of you are in that spot as well.

It’s not the losing that’s the problem—it’s the maintaining. When you consider the simplicity of it, why is it so difficult to sustain a way of eating that keeps you at a healthy weight? Scientists and physicians have examined genetics, proteomics, hormones, and more. They have looked at every psychological issue they can think of to try to help people lose the weight and keep it off. No luck so far.

I’ll go out on a limb and predict there won’t be any one answer. It’s really up to each individual to find a way to eat that can sustain a normal body weight. It will probably be slightly different for each of us as to the types of foods and exercise we use, but our solution exists. We just have to find a way to be consistent and in the case of weight loss, it has to be for life.

The Bottom Line

We face plenty of obstacles in our path to health. We may not have the best genes. We may have had a poor lifestyle for many years that we have to compensate for. We may not have all the resources we need. But if we can pick a couple of things at a time and make them our habits for life, we can begin the process. We just have to be consistent, day in, day out. Where we end up may not be perfect, but it can be better than you are right now. That’s what aging with a vengeance is all about.

Will the Polypill Reduce Second Heart Attacks?

/in /by

One of the issues with prevention is having people stick to a plan, even after an event as serious as a heart attack. Lifestyle changes are challenging to stick with, but so is something as simple as taking medications. Remember, this isn’t to prevent a heart attack; it’s to prevent a second one. That’s serious.

The concept of a polypill has been around for close to 15 years. The idea was to put medications together in one pill as a preventive that would reduce the risk of getting cardiovascular disease. For a long time, that idea never went anywhere, but recently researchers decided to resurrect the concept. This time, the objective was to monitor subjects with recent heart attacks. Would there be a difference in the rate of secondary events between subjects who took the polypill and those who took the same medications as individual pills? The medications used were aspirin, ace-inhibitor, and a statin. After three years of follow-up, the subjects in the polypill experienced significantly fewer secondary events, 9.5% versus 12.7%.

Can you figure out why the subjects who took the polypill did better than the subjects who took the same medications individually? I’ll tell you the secret to disease prevention on Saturday.

Want Fewer Medications? Change Your Lifestyle

/in /by

The study that we examined on Tuesday showed that a regular exercise program can help reduce the number of medications related to cardiovascular disease and type 2 diabetes. We’re not talking about youngsters; 51 subjects completed the study with an initial mean age of 54. There were some outcomes that were likely unexpected; for example, waist circumference did not change between the experimental group and control group over the five years. There was a significant decrease in body fat in the exercise group that explained the difference in body weight. Still, the control group lost about two pounds in five years while the exercise group lost about six pounds. That actually turns out to be a good thing, as I’ll explain a little later.

The Exercise Program

The high-intensity interval training was just as advertised: intense. It included a 10-minute warm up, followed by four 4-minute intervals at 90% of maximum heart rate (HRMax) interspersed with 3 minutes of active recovery. They finished with a 5-minute cooldown. They used percentage of HRMax as assessed in the exercise test, because that’s an intense level. The focus is on the 4 minutes but those 4 are brutal. You do get to rest, but then you have to do it over again, and that’s a significant challenge to the cardiovascular system. As people got fitter, the intensity would be changed to sustain the 90% level.

What surprised me was that there was no organized exercise activity in the other eight months of the year; they just kept track of activity levels using the activity monitors. There were no differences between the control group and the exercise group in the eight months with no organized activity. That’s interesting.

Most Variables Didn’t Change

This probably surprised the researchers, but it was a desirable outcome. There were no significant differences in body fat, waist circumference, BMI, or overall percentage of body fat. While the subjects probably would have liked to have lost more weight, the fact that they didn’t shows that the changes that occurred in the risk factors for cardiovascular disease, such as high blood pressure and low HDL cholesterol as well as a lower insulin levels, showed that the difference was the actual exercise program itself. The differences in distribution of nutrients in the diet and in the total caloric intake were insignificant. As I mentioned earlier, the number of steps per day and other activities were still even. That means, again, the changes could be attributed to the exercise program alone.

The Bottom Line

What is abundantly clear is that if you really want to reduce medications, you have to pay the price by changing your lifestyle. In this study they focused on one variable: exercise. If you add a change in dietary intake, and or a change in the distribution nutrients, you may get even more benefits. But for me, it answers the question that I started with. You want to reduce medications? Change your lifestyle.

Is it worth it? That’s your call. But that’s what Aging with a Vengeance is all about.

Can You Reduce Your Medications?

/in /by

One of the questions that I get asked frequently goes something like this: “Dr. Chet, how can I reduce the medications I’m taking?” Along with that question is, “I don’t want to have to take medications for blood pressure or cholesterol or diabetes. What can I do?” As we proceed with a focus on Aging with a Vengeance, a recently published study illustrated at least a partial answer to these questions.

Researchers in Spain recruited 64 subjects for an exercise program. The exercise program was a high-intensity interval training (HIIT) program, three days a week, that ran for four months under staff supervision. The rest of the year these subjects were given activity monitors that automatically uploaded data on activity, sleep, etc. The researchers also took a variety of blood samples for testing metabolic variables, tested the subjects’ fitness levels, assessed anthropomorphic measures such as body weight and waist circumference, and recorded medications related to blood pressure, cholesterol, triglycerides, and blood sugars. The subjects were retested after two years and again after five years.

Over the period of five years, an amazing 51 subjects completed the exercise sessions and all the testing required. That, in and of itself, is remarkable—I’ve done this type of study, and holding on to the subjects is one of the main challenges.

The primary question was answered: those who exercised as the study required took fewer medications for blood pressure, cholesterol, and blood sugar control. As you might expect, that isn’t the entire story, so we’ll wrap this up on Saturday.

Online Prescriptions? Good Grief!

/in /by

If you listen to the radio, surf the Internet, or watch television, you might have heard a pitch for a discreet way to treat sexual problems, hair loss, even depression and anxiety: just visit their website. These are not pitches for supplements or other non-traditional treatments; they’re for medications that can fix your problem.

Don’t you need a prescription for those? Yes, and you can have a confidential chat online with a physician to get one for the solution to your problem. The “examination” may just be the answers to a few questions about your health or more detailed if the issue is more complex. But when it’s done, you get the prescription and can order it for discrete delivery, right to your door.

Online medical examinations? No. They’re simply a review of symptoms in order sell you a medication. What could go wrong? We don’t know yet because there’s no research that’s examined the issue. If a man wants a drug for erectile dysfunction and isn’t truthful about medications or cardiac issues, that could prove to be fatal. There are also problems with non-traditional uses for medications such as using a beta-blocker, typically prescribed for high blood pressure, for performance anxiety. Again, what could go wrong? So, so much.

The Bottom Line on the 2018 Cholesterol Guidelines

/in /by

In Thursday’s Memo, I talked about the 2018 Cholesterol Guidelines and evidence-based medicine, focusing on the physician side of the treatment discussion. But I believe that’s not the most important part of the discussion; I think the critical part is the patient side. Here’s why.

The Cholesterol Guidelines focus on lifestyle changes first: a healthier diet, exercise, quitting smoking, and weight loss. That’s supposed to be the initial part of the potential treatment plan—lifestyle first. In other words, what will the patients do for themselves before the discussion leads to medications, especially statins?

The guidelines aggressively focus on the use of statins and other medications to get the LDL-cholesterol to desirable levels, so we have a dilemma during the discussion of a treatment plan. Do the physicians assume, based on experience, that the patients won’t do what they’re supposed to do to lower their risk of CVD and immediately prescribe medications? Or do the patients take the lifestyle route seriously and do what’s necessary to change their health?

To be blunt, we patients haven’t done our part. We lose weight and gain it back. We start to eat healthier and don’t sustain it. We start to exercise, but we let life get in the way and stop, or we push too hard and get injured and stop, or the weather turns colder or hotter and we stop. When we agree to change our health habits and then don’t follow through, we make our health issues worse—they’re still in there eating away at our lifespan and not being treated.

Don’t make promises you know you won’t keep; notice I didn’t say can’t keep, I said won’t keep. If you know in your heart you’ll never change your diet or keep up with exercise, the best thing you can do for your health is don’t delay: start taking the meds and start taking care of the problem.

Although I disagree with it, I get why physicians jump to meds. There’s only one way to change that: we have to prove them wrong when they assume we won’t stick to a healthier lifestyle.

The Bottom Line

The 2018 Cholesterol Guidelines put the responsibility for lowering the risk of CVD without medications in our hands—the patients. Work out a timeline with some concrete goals for each lifestyle area with your physician. It won’t be easy: regular exercise for life, eating better from now on, quitting smoking, plus getting to a normal weight and staying there will all take time and consistent effort. That’s okay because even if your risk of CVD is high, it doesn’t mean you drop dead tomorrow. Even if you fall into an at-risk scenario, I know you can do it. There are many tools to help you keep at it: an app, a workout buddy, a Facebook group, and more.

Instead of looking at your health challenge as an obstacle, look at it as an opportunity for better health. If you say you don’t want to take medications, this is your chance to prove whether you really mean it. I can’t guarantee you’ll never need the meds, but you can work your way down to a smaller dosage with fewer side effects.

It all depends on your answer to one question: what are you prepared to do today?

Aspirin and Unintended Consequences

/in /by

We began the week considering a type of shortcut to health called biohacking. The polypill was a biohack to reduce the risk of CVD events, but there’s no research showing whether the polypill will ever prove to be effective. However, the results of the ASPREE trial may give us an idea whether the long-term trials should ever be attempted (1-3). Let’s take a look at the results of the ASPREE trial and the effects of an aspirin a day on healthy older adults.

In the first paper, the researchers evaluated the data to see if those who took the aspirin had less disability (1). In other words, did taking the aspirin convey benefits that reduced the risk of death, disability, or dementia? The data showed no differences between the aspirin and placebo group as it related to those outcomes.

In the second paper, the researchers examined the differences in all-cause mortality (2). What surprised the researchers was a slight increase in death from cancers in the group that took the aspirin; no specific type of cancer seemed to be impacted. Because aspirin has been shown to be beneficial in almost all other studies of cancer and mortality, the researchers said the results should be taken with a degree of caution.

In the final paper, researchers examined whether aspirin reduced the rate of CVD events and stroke (3) and found no difference, but the risk of hemorrhagic stroke was significantly higher in the aspirin group versus the placebo. This was the primary reason the study was terminated after five years.
 

The Problem

There were several problems with the study including the low adherence in both the aspirin and placebo group: if people didn’t take the pills, obviously that impacts the results. But the biggest question I have is a very simple one: who thought it was a good idea to give healthy people a medication every single day? Taking an aspirin for a headache or muscle ache is one thing. Taking it when you don’t need it is another.

The study demonstrated the logical fallacy of the polypill. “People won’t take care of themselves, so let’s put everyone on the medications that can reduce the risk of CVD.” No, let’s not. The results were unintended consequences that put the entire idea of biohacking into question.
 

The Bottom Line

When it comes to health, there are no real shortcuts. Biohacking, while a cute contemporary term, is fool’s gold. Yes, you can use your time and resources more efficiently to improve your health, but there are no shortcuts.

There is also one other obvious conclusion. Healthy people shouldn’t take medication. I take an 81 mg aspirin every day because I have had a stent and my doctor told me to. But I don’t take a statin any more because I changed my diet and lifestyle to keep my cholesterol normal. I control my blood pressure with diet and exercise. I don’t take medications I don’t need.

If you’re willing to do all you can to avoid medications and you still need medication to help you out, do it. But don’t take them to avoid doing the work. There are unintended consequences of taking the easy way out.

What are you prepared to do today?
