Have you ever wondered what actually happens during a heart attack? Dr. Pradip Jamnadas, MD, a renowned cardiologist from Cardiovascular Interventions in Orlando, Florida, breaks it down in a way that’s both simple and eye-opening. If you think you know everything about heart attacks, think again. The truth might surprise you—and it could save your life.

Let’s dive into the fascinating, and sometimes terrifying, world of heart health. This isn’t just another dry medical explainer. Dr. Jamnadas’s video is packed with insights that challenge conventional thinking. And here’s the kicker: even if you feel fine, you could be walking around with a ticking time bomb in your chest. Ready to learn more? Let’s get started.

The Anatomy of a Heart Attack

First, let’s talk about what a heart attack actually is. Spoiler alert: it’s not just a blocked artery. According to Dr. Jamnadas, heart attacks are caused by a complex interplay of factors, many of which you might not even be aware of. To understand this, we need to take a closer look at your arteries.

Imagine your artery as a three-layered tube. Over time, plaque—a sticky substance made of fat, cholesterol, and other materials—can build up inside these layers. But here’s the twist: most of this plaque doesn’t accumulate on the inside of the artery. Instead, it builds up on the outside, causing the artery to swell. It’s like if you stuffed a sock into a garden hose—the water might still flow, but not as well as it should.

Why Stress Tests Aren’t Always Enough

You’ve probably heard of stress tests, right? These are often used to check for heart disease. But here’s the shocker: even if you pass a stress test with flying colors, it doesn’t mean you’re in the clear. According to Dr. Jamnadas, a blockage has to be more than 70% before it restricts blood flow enough to show up on a stress test. That means you could have a 50% blockage and feel completely fine—until that plaque suddenly cracks.

When plaque cracks, it’s like old wallpaper bubbling up. A blood clot forms, and suddenly, the flow of blood through that artery is compromised. If the clot completely blocks the artery, you’re looking at a full-blown heart attack. It’s like a traffic jam in your bloodstream—and the results can be catastrophic.

Unstable Angina and Mini Heart Attacks

But what if the clot only partially blocks the artery? This can lead to something called unstable angina. You might experience new chest pain, but it’s not yet a heart attack. The danger here is that the blockage could worsen over time, leading to more severe symptoms—or even a major heart attack.

There’s also something called a mini heart attack, or a non-STEMI. This happens when tiny pieces of the clot break off and travel into the heart muscle. You might have severe chest pain and positive blood tests, but your EKG won’t show the classic signs of a heart attack. It’s like a sneak attack on your heart, and it’s every bit as dangerous as the real thing.

What Makes Plaque Rupture?

So, what causes plaque to crack in the first place? According to Dr. Jamnadas, it’s not just about high cholesterol or diabetes. Factors like hyperinsulinemia (too much insulin in your blood), high blood pressure, and inflammation can make your plaques unstable. Even conditions like inflammatory bowel disease or skin diseases can increase your risk. It’s like your body is a house of cards—one weak spot, and the whole thing can come crashing down.

Can You Live With Plaque?

Here’s the million-dollar question: can you live with plaque in your arteries? The answer is yes—but only if it’s stable. Dr. Jamnadas emphasizes that you can be 95 years old with extensive plaque and still be fine—as long as it’s not blocking more than 70% of your artery. The key is to keep your plaques from cracking, and that means managing your risk factors.

How to Protect Your Heart

So, what can you do to protect your heart? First, get regular check-ups. Tests like calcium scoring studies and CT angiograms can give you a clear picture of your heart health. Second, manage your risk factors. If you have diabetes, high blood pressure, or high cholesterol, work with your doctor to get these under control. And finally, adopt a heart-healthy lifestyle. Eat a balanced diet, exercise regularly, and avoid smoking.

The Bigger Picture

Heart disease is the leading cause of death worldwide, but it doesn’t have to be. By understanding the risks and taking proactive steps, you can significantly reduce your chances of having a heart attack. The key is to stay informed and take action before it’s too late.
