Why Is Heart Disease Still a Leading Cause of Death?
Understanding the Risks—and What You Can Do About Them After 50
By Coach Marcus Jones
We hear a lot about new health trends.
New supplements.
New diets.
New medications.
New technology.
New ways to supposedly live longer.
But despite all of those advances, cardiovascular disease remains one of the biggest health challenges in the world.
In the United States, heart disease continues to be a leading cause of death.
That raises an important question:
WHY?
We know more about heart health than ever before.
We have medications that lower cholesterol.
Medications that control blood pressure.
Better emergency treatment for heart attacks.
More advanced cardiac procedures.
Better diagnostic testing.
And decades of research showing us many of the behaviors associated with cardiovascular risk.
Yet heart disease remains a major problem.
I believe part of the answer is something we have talked about throughout this Healthy Aging After 50 series:
Knowing what to do and consistently doing it are two very different things.
Heart disease usually doesn't develop because of one meal, one stressful day, or one missed workout.
Risk often builds over years.
Sometimes decades.
That's exactly why heart health deserves our attention after 50.
Not because we should live afraid of having a heart attack.
But because there are risk factors we can identify, discuss with our healthcare providers, and often work to improve.
Today, let's talk about them.

QUICK ANSWER: WHY IS HEART DISEASE STILL A LEADING CAUSE OF DEATH?
Heart disease remains a leading cause of death because cardiovascular risk develops from a combination of factors including aging, high blood pressure, abnormal cholesterol, diabetes, smoking, physical inactivity, obesity, diet, genetics, and other medical and lifestyle factors.
Some risk factors cannot be changed, including age and family history.
Others can often be improved.
Regular physical activity, not smoking, managing blood pressure and cholesterol, controlling diabetes, eating a heart-supportive diet, maintaining an appropriate body weight, getting adequate sleep, and receiving regular medical care can all play important roles in reducing cardiovascular risk.
No lifestyle can guarantee that heart disease will never occur.
But reducing known risk factors matters.
FIRST, WHAT DO WE MEAN BY "HEART DISEASE"?
People sometimes use "heart disease" as though it describes one condition.
It doesn't.
Heart disease is a broad term that can include several cardiovascular conditions.
These can involve:
Coronary arteries.
Heart rhythm.
Heart valves.
Heart muscle.
Heart structure.
For today's discussion, we're going to focus primarily on coronary artery disease, because it is a major form of heart disease and a common underlying cause of heart attacks.
WHAT IS CORONARY ARTERY DISEASE?
Your heart is a muscle.
And like every other muscle, it needs oxygen-rich blood.
The coronary arteries supply that blood.
Over time, cholesterol-containing deposits called plaque can accumulate within artery walls.
This process is called:
ATHEROSCLEROSIS.
Atherosclerosis doesn't usually develop overnight.
It can begin years or even decades before someone experiences symptoms.
As plaque builds, arteries may narrow.
In some circumstances, a plaque can rupture.
The body responds by forming a blood clot.
If that clot suddenly blocks blood flow through a coronary artery, part of the heart muscle may lose its oxygen supply.
That's a heart attack.
And here's the important part:
A person may feel perfectly normal while cardiovascular disease is developing.
WHY AGE MATTERS
Age itself is an important cardiovascular risk factor.
That doesn't mean:
"You're over 50, so heart disease is inevitable."
It isn't.
But our cardiovascular system changes as we age.
Arteries can become stiffer.
Blood pressure may increase.
Years of exposure to other risk factors begin adding up.
Think about it.
Someone who has smoked for 30 years hasn't had one year of exposure.
They've had decades.
Someone with uncontrolled high blood pressure may have been placing additional stress on blood vessels for years.
Someone with elevated LDL cholesterol may have experienced long-term exposure to that risk factor.
That's why I view turning 50 as a wake-up call.
Not a death sentence.
It's a great time to ask:
What are my numbers?
What are my risks?
And what can I improve?
RISK FACTOR #1: HIGH BLOOD PRESSURE
High blood pressure is one of the most important cardiovascular risk factors.
And it has a dangerous characteristic:
YOU MAY NOT FEEL IT.
Someone can have high blood pressure and feel completely normal.
Meanwhile, chronically elevated pressure can contribute to damage involving:
Blood vessels.
Heart.
Brain.
Kidneys.
And other organs.
That's why checking your blood pressure matters.
Don't rely on symptoms.
Know your numbers.
Later this week, we're going to talk specifically about the best times and methods for checking blood pressure.
RISK FACTOR #2: CHOLESTEROL
Cholesterol conversations can become confusing.
Let's simplify them.
Your body needs cholesterol.
It helps produce:
Cell membranes.
Hormones.
Vitamin D.
And other important substances.
The problem isn't simply:
"Cholesterol is bad."
One important concern involves elevated levels of LDL cholesterol and other atherogenic lipoproteins, which can contribute to plaque formation within arteries.
HDL cholesterol participates in cholesterol transport and is associated with cardiovascular risk in a different way, but simply trying to "raise HDL" isn't the main goal of modern prevention.
Your overall cardiovascular risk matters more than one isolated number.
That's why cholesterol results should be interpreted in context with your healthcare provider.
RISK FACTOR #3: DIABETES
Diabetes significantly increases cardiovascular risk.
Over time, elevated blood glucose can damage blood vessels and contribute to processes involved in atherosclerosis.
People with diabetes also commonly have additional cardiovascular risk factors, including:
High blood pressure.
Abnormal cholesterol.
Excess body weight.
Insulin resistance.
This is one reason metabolic health deserves attention long before someone develops serious complications.
Later this week we'll talk specifically about:
INSULIN RESISTANCE.
Understanding it can help you understand why metabolic health and cardiovascular health are so closely connected.
RISK FACTOR #4: SMOKING
If someone asks me for one lifestyle change with major cardiovascular implications, quitting smoking belongs near the top of the list.
Smoking damages blood vessels.
It promotes inflammation and clot formation.
It reduces oxygen delivery.
It accelerates atherosclerosis.
And it substantially increases cardiovascular risk.
The good news?
Cardiovascular risk begins improving after someone quits.
It doesn't matter whether you've smoked for five years or 35 years.
Quitting still matters.
RISK FACTOR #5: PHYSICAL INACTIVITY
Our bodies were built to move.
But modern life makes sitting incredibly easy.
We sit:
At work.
In the car.
Watching television.
Using computers.
Scrolling phones.
Eating.
Traveling.
Then sometimes we wonder why our bodies aren't functioning the way we want them to.
Regular physical activity is associated with lower cardiovascular risk and can help improve:
Blood pressure.
Blood sugar.
Fitness.
Body composition.
Sleep.
Stress management.
And overall cardiovascular health.
You don't have to become a marathon runner.
Walking matters.
Strength training matters.
Movement throughout the day matters.
Consistency matters.
RISK FACTOR #6: EXCESS BODY WEIGHT AND METABOLIC HEALTH
Body weight is another topic that deserves nuance.
Weight alone doesn't tell us everything about someone's health.
But excess body fat—particularly visceral fat around the abdominal organs—is associated with metabolic abnormalities that can increase cardiovascular risk.
These may include:
Insulin resistance.
High blood pressure.
Elevated triglycerides.
Abnormal glucose.
Chronic low-grade inflammation.
The goal shouldn't simply be:
"Get skinny."
The better goal is:
IMPROVE METABOLIC HEALTH.
Build muscle.
Reduce excess body fat when appropriate.
Improve cardiovascular fitness.
Control blood pressure.
Improve blood sugar.
Eat nutritious food.
Those outcomes matter.
RISK FACTOR #7: DIET
There is no single magical "heart disease prevention food."
Your overall dietary pattern matters much more.
Dietary patterns associated with cardiovascular health generally emphasize foods such as:
Vegetables.
Fruits.
Whole grains.
Beans.
Legumes.
Nuts.
Seeds.
Fish.
Unsaturated fats.
And minimally processed foods.
At the same time, limiting excessive amounts of:
Sodium.
Added sugar.
Highly processed foods.
Certain saturated-fat-rich foods.
And trans fats...
can be helpful depending on the individual.
You don't need a perfect diet.
You need a consistently better one.
WHAT ABOUT SUPPLEMENTS?
Because we've spent much of Nutrition & Wellness Week discussing supplements, this is worth addressing.
There is no dietary supplement that makes heart disease impossible.
Not Black Seed Oil.
Not MCT Oil.
Not fulvic minerals.
Not a multivitamin.
Not an herb.
Not a powder.
Supplements may have specific roles for specific people.
But they don't erase:
Smoking.
Uncontrolled blood pressure.
Untreated diabetes.
Physical inactivity.
Poor nutrition.
Or serious cardiovascular disease.
That's why I always come back to the foundation.
Supplements can be tools.
They are not substitutes for the fundamentals.
RISK FACTOR #8: FAMILY HISTORY AND GENETICS
This is one risk factor you can't change.
If cardiovascular disease runs in your family, pay attention.
Family history can provide clues about inherited risk involving:
Cholesterol.
Blood pressure.
Diabetes.
Clotting.
Cardiomyopathies.
And other cardiovascular conditions.
Some people inherit genetic conditions such as familial hypercholesterolemia that can cause very high LDL cholesterol from an early age.
You cannot change your genes.
But knowing your family history may help you and your healthcare provider make better decisions about screening and treatment.
Genetics isn't destiny.
But it is information.
CAN SOMEONE LOOK HEALTHY AND STILL HAVE HEART DISEASE?
Yes.
This is important.
Someone can:
Exercise.
Look lean.
Feel energetic.
And still have cardiovascular risk factors.
That's why appearance isn't a medical screening test.
You can't see:
Blood pressure.
LDL cholesterol.
Blood glucose.
Coronary plaque.
Certain heart rhythm abnormalities.
Or genetic risk...
by looking in the mirror.
That's another reason regular medical care matters after 50.
HEART DISEASE CAN BE SILENT
One reason cardiovascular disease remains dangerous is that it may develop without obvious symptoms.
Some people discover cardiovascular disease only after experiencing:
Chest discomfort.
Shortness of breath.
A heart attack.
Or another cardiovascular event.
That doesn't mean everyone needs every available cardiac test.
Screening should be individualized.
But adults should know basic cardiovascular risk factors such as:
Blood pressure.
Cholesterol.
Blood sugar.
Smoking status.
Family history.
Physical activity.
And other relevant health information.
KNOW YOUR NUMBERS
One of the most practical things you can do after 50 is understand your health data.
Talk with your healthcare provider about numbers such as:
BLOOD PRESSURE
Know whether your readings are within the range recommended for you.
CHOLESTEROL
Understand LDL, HDL, triglycerides, and your overall cardiovascular risk.
BLOOD GLUCOSE
Know whether your blood sugar is within a healthy range.
A1C
For appropriate individuals, HbA1c can provide information about average blood glucose over approximately the previous two to three months.
BODY COMPOSITION AND WAIST SIZE
These aren't perfect measures, but they can provide useful information about metabolic risk.
Don't become obsessed with numbers.
Use them as information.
WHAT CAN YOU DO TO REDUCE YOUR RISK?
Here's where I want this article to become practical.
We can't control everything.
But we can control a lot.
1. DON'T SMOKE
If you smoke, getting help to quit may be one of the most important things you can do for your cardiovascular health.
2. KNOW YOUR BLOOD PRESSURE
High blood pressure often produces no obvious symptoms.
Measure it appropriately and discuss consistently elevated readings with your healthcare provider.
3. KNOW YOUR CHOLESTEROL
Don't guess.
Get tested.
4. PAY ATTENTION TO BLOOD SUGAR
Especially if you have risk factors for prediabetes or diabetes.
5. MOVE YOUR BODY
Aim to build a lifestyle that includes both aerobic activity and strength training when medically appropriate.
6. EAT MOSTLY NUTRIENT-DENSE FOODS
Make vegetables, fruits, whole grains, beans, nuts, seeds, lean proteins, and healthy fats regular parts of your diet.
7. PROTECT YOUR SLEEP
Poor sleep and sleep disorders can affect cardiovascular health.
If you snore heavily, stop breathing during sleep, or experience significant daytime sleepiness, talk with a healthcare professional about possible sleep apnea.
8. MANAGE STRESS
You can't remove every stressful situation from life.
But you can develop healthier ways to respond to stress.
9. MAINTAIN REGULAR MEDICAL CARE
Don't wait until something hurts.
Prevention-oriented care includes identifying risks before they become emergencies.
WHAT ABOUT EXERCISE AFTER 50?
Exercise is one of the most powerful lifestyle tools available to us.
Adults generally benefit from a combination of:
Aerobic activity.
Strength training.
Balance work.
Mobility.
And regular movement throughout the day.
If you've been inactive for years or have known cardiovascular disease or significant symptoms, talk with your healthcare professional before beginning a vigorous exercise program.
The goal isn't proving how tough you are.
The goal is being able to keep moving for decades.
KNOW THE WARNING SIGNS OF A HEART ATTACK
This part could save a life.
Heart attack symptoms can vary.
Possible warning signs include:
Chest pressure, squeezing, fullness, discomfort, or pain
Discomfort spreading to one or both arms, the back, neck, jaw, or stomach
Shortness of breath
Cold sweat
Nausea
Lightheadedness
Unusual weakness or fatigue
Not everyone experiences dramatic crushing chest pain.
Symptoms can be different in women, older adults, and people with diabetes.
If you think you or someone else may be experiencing a heart attack:
CALL 911 OR YOUR LOCAL EMERGENCY NUMBER IMMEDIATELY.
Don't attempt to diagnose a possible heart attack through an internet search.
Don't drive yourself if emergency medical services are available.
Time matters.
MYTHS VS. FACTS
Myth: Heart disease only affects older people.
Fact: Cardiovascular disease can develop over decades, and risk factors may be present long before symptoms appear.
Myth: If I exercise, I don't need to worry about cholesterol or blood pressure.
Fact: Exercise is extremely valuable, but physically active people can still have hypertension, abnormal cholesterol, diabetes, or genetic cardiovascular risk.
Myth: If I feel good, my heart must be healthy.
Fact: Many cardiovascular risk factors cause no obvious symptoms.
Myth: Heart disease is completely preventable.
Fact: Many risk factors can be modified, but no lifestyle can guarantee that cardiovascular disease will never occur.
Myth: Supplements can protect me from a poor lifestyle.
Fact: No supplement replaces smoking cessation, physical activity, nutritious food, appropriate weight management, sleep, risk-factor control, and medical care.
COACH MARCUS TAKEAWAYS
Here's what I want you to remember.
1. Heart disease often develops over many years.
2. You can have cardiovascular risk factors without feeling sick.
3. Age increases risk, but heart disease isn't an inevitable consequence of getting older.
4. High blood pressure, abnormal cholesterol, diabetes, smoking, and inactivity are major modifiable risk factors.
5. Family history and genetics matter even though we cannot change them.
6. Regular exercise and strength training can be important parts of cardiovascular health.
7. Nutrition matters more than any single "heart healthy" food or supplement.
8. Know your blood pressure, cholesterol, blood sugar, and personal risk factors.
9. Regular medical care can identify problems before symptoms appear.
10. Heart attack symptoms require immediate action.
MY FINAL THOUGHT
When I think about healthy aging after 50, heart health sits near the top of the list.
Why?
Because everything we want to do depends on being alive and healthy enough to do it.
Travel.
Exercise.
Work.
Build businesses.
Spend time with family.
Serve others.
Enjoy retirement.
Live our purpose.
None of those things matter much if we continually ignore our health.
I don't believe we should live scared of heart disease.
I believe we should live informed.
Know your numbers.
Know your family history.
Move your body.
Build muscle.
Eat better.
Don't smoke.
Protect your sleep.
Manage your stress.
Go to the doctor.
Take prescribed medications appropriately when you need them.
And don't assume feeling good means everything is good.
After 50, prevention-oriented living isn't about becoming obsessed with disease.
It's about protecting your ability to live.
You can't control every outcome.
None of us can.
But you can improve the way you take care of yourself today.
And those decisions add up.
Because getting older is automatic.
Getting better requires intention.
And remember:
DON'T JUST GET OLDER. GET BETTER AT IT.
Faith. Health. Wealth. Build All Three.
