Hi, and welcome to Day 13.

Yesterday, I mentioned that cholesterol was my favorite topic and that I could talk about it for hours. Well, today we’re talking about blood pressure, and I have to confess—it’s probably equally my favorite.

I don’t want to sound boring or dull, but while many of my colleagues get excited about inserting new heart valves, placing stents, or implanting devices to help failing hearts, I get really excited when we can do the simple things really well. And one of the simplest yet most powerful things we can control is blood pressure.

Why is Blood Pressure So Important?
Let me paint a picture for you. Imagine my blood pressure is 100/120, which is absolutely fine. Over time, it creeps up to 130-135 systolic. Should I be worried? Should my doctor say, “Your blood pressure is a little high, let’s just keep an eye on it”?

Well, consider this: Going from 100 to 130-135 is about a 10% increase. And your heart beats 100,000 times a day. Do you really want your heart—the most important pump in your body—to work 10% harder than necessary? I certainly wouldn’t.

The Consequences of High Blood Pressure
Raised blood pressure has serious effects on your body:

It damages arteries, increasing the risk of stroke and heart attack.

It puts stress on the heart, which can lead to atrial fibrillation (AFib) and heart failure.

It harms the kidneys, damaging the delicate glomerular filtering system, which can lead to renal failure.

It’s linked to dementia, and studies suggest that lowering blood pressure can help reduce dementia risk.

So, in short, high blood pressure increases your risk of stroke, heart attack, heart failure, kidney failure, and dementia. That’s why controlling it is so critical.

What Should You Do?
If you haven’t had your blood pressure checked recently, go and get it done. If it’s even slightly high, don’t let your doctor say, “Let’s just keep an eye on it and check again in a few months.” It’s not their heart, it’s yours.

One tool I frequently use is a 24-hour blood pressure monitor. This is a cuff you wear for an entire day, taking multiple readings to give a detailed picture of your blood pressure patterns. It can help detect white coat syndrome (when blood pressure spikes at the doctor’s office) and identify high nighttime blood pressure, which is particularly concerning.

Final Thoughts
Be sure to check out today’s resources—there’s a lot of great information to dive deeper into this topic. But above all, get your blood pressure checked and make sure it’s properly controlled.

At 100,000 beats per day, your heart deserves to work as efficiently as possible. Take care of it.

I look forward to seeing you tomorrow. Live as well as possible for as long as possible. Take care and bye for now.

Are You at Risk of a Sudden Heart Attack? How Healthy is Your Heart? Really?

Heart disease is the #1 killer in the Western World. In Australia, someone dies every 28 minutes from heart disease. That’s 51 people a day. In the US, someone has a heart attack every 40 SECONDS! Fortunately, many heart attacks are preventable. However, regular exercise and eating healthy are no guarantee you won’t succumb to this silent killer.

94% of Australians have at least One Risk Factor for heart disease.
59% of Australians have been Touched by heart disease.
Yet only 3% of Australians have had a Full Heart-Health Assessment in the past 12 months.

**Episode Title: "Day 13: Blood Pressure and Heart Disease"** **Speaker:** Hi and welcome to day 13. Well, yesterday I think I said that cholesterol was my favourite topic and I'd talk about it for hours. Well, today we're talking about blood pressure, and my confession is this is probably equally my favourite. And I don't want to be thought of as boring or dull because most of my colleagues who are excited about putting in new valves, putting in stents when people are having heart attacks, or putting in devices to help people's hearts function, get all excited about the, well, I guess the expensive shiny toys that we can do when it comes to cardiology. And me? I seem to get really excited when we can do the really simple things well. And one of those really, really simple things is blood pressure. And before I go too far, I really want you to understand why I get so focused on it. Well, let me paint this picture. Imagine I've got a blood pressure of, well, say, 120. And that's my blood pressure. It's absolutely fine. But it creeps up over time to say... about 130, 135 systolic. Should I be worried about that? Should my GP say things like, "Oh, your blood pressure's up a little bit. Maybe we should keep an eye on it. Let's check again in six months' time." And so on. Well, let me frame that up for you. Going from 100 to 130 to 135 is a 10% increase. And when you think about it, your heart is beating 100,000 times a day. 100,000 times a day. When you think of it like that, would you really want your heart, the most important pump in your body, in your life, to be working 10% harder than it needs to? I don't think so. Blood pressure is so important because it's so easy to get under control. We've got really good medications for it. And raised blood pressure has such deleterious effects. Increasing the blood pressure puts wear and tear on the arteries. Once you start to damage the arteries, you can have problems with the arteries going to the brain, causing stroke, and the arteries going to your heart, causing heart attack. You can also put stress on the heart itself. You can stretch it a bit out of shape. And if you stretch the top chambers of the heart, the atria, you can drive atrial fibrillation. If you put load on the bottom chambers of the heart, the ventricles, you can end up getting cardiac failure. That raised blood pressure also goes through the glomerular, the small structures, the blood vessels of the kidneys. And you guessed it, if you're driving too much pressure through your filtering system, you can damage your filtering system as well—renal failure. And we're getting more and more evidence that raised blood pressure is linked to dementia, and lowering blood pressure can push dementia away. So think about it. Increasing your blood pressure increases your risks of stroke, heart attack, atrial fibrillation, cardiac failure, renal failure, and even dementia. So if you've not had your blood pressure checked lately, go and get it done. If there's any question about it, don't let your doctor say, "Look, we'll keep an eye on it and we'll check it in a few weeks or a few months or next year." It's not his heart. It's not his body. It's yours. One of the things I use a lot is a 24-hour blood pressure monitor. That's a cuff you wear for a whole 24-hour period. It takes multiple measurements, so it gives us a really, really good idea of exactly what we're dealing with. It tells us if someone's got white coat syndrome or not. It tells us if your blood pressure's up overnight while you're sleeping. Look, do check out the resources today because there's some good stuff in there to get more information. But whatever happens, please get your blood pressure checked, and please get it properly controlled. It pays huge dividends at 100,000 beats a day. Look after your heart by reducing the load that it's working against. I look forward to seeing you tomorrow. I do wish you the very best. I hope you live as well as possible for as long as possible. Take care and bye for now.

Please Note: Before embarking on the Younger Longer 28-Day Heart Health Challenge, it's essential to consult with your General Practitioner (GP) to ensure it's safe for you to participate, especially if you have existing health conditions or risk factors. Pre-exercise screening is recommended to identify any medical conditions that may increase the risk of adverse events during physical activity.
