Heart Disease Is the #1 Killer, But Are We Making Progress?


Heart Disease Is the #1 Killer, But Are We Making Progress?

You have probably heard this before.

Heart disease is the number one cause of death for both men and women in the United States.

That has been true for more than a century, except for the influenza pandemic of 1918 and 1919.

So it raises a fair question, and one I get now and then.

If it’s been such an issue for so long, it can’t possibly be just our diet, right?

and

If we know so much more now than we did decades ago, are we actually making progress?

The short answer is yes. But the full answer is more complicated. It’s always more than just the short answer.

What Counts as “Heart Disease”?

When we talk about heart disease in this context, we are usually referring to a group of conditions known as cardiovascular disease.

This includes:

  • Coronary artery disease (CAD)

  • Heart attacks (MI or myocardial infarction)

  • Heart failure (sometimes referred to as congestive heart failure, CHF)

  • Stroke

  • Other conditions affecting the heart and blood vessels, like high blood pressure or hypertension

The most common contributor is atherosclerosis, which is the buildup of plaque in the arteries. Over time, this can restrict blood flow or lead to blockages. This is about the road closures on the highway, and then an accident happens. Restricted lanes and then an entire blockage. That’s problematic.

So when statistics say heart disease is the number one killer, they are referring to this broader category.

Has It Always Been the #1 Killer?

For the most part, yes.

Aside from the spike in deaths during the influenza pandemic, heart disease has consistently been the leading cause of death in the United States.

During the COVID pandemic in 2020-2021, COVID was the #3 cause of death, while heart disease and cancer remained at #1 and #2, respectively. https://www.cdc.gov/nchs/data/databriefs/db427-tables.pdf#4

That does not mean nothing has changed.

In fact, quite a bit has changed.

So Are We Making Progress?

Yes, we are.

Over the past several decades, death rates from heart disease have declined significantly, especially when adjusted for age.

More people survive heart attacks than ever before. Medical care has improved. Emergency response is faster. Treatments are more effective.

But at the same time, heart disease remains the leading cause of death.

Why?

Because progress in some areas is balanced by challenges in others.


Can You Have Heart Disease Without Symptoms?

Yes.

Heart disease can develop over many years without obvious symptoms. Conditions like atherosclerosis, which is the buildup of plaque in the arteries, often progress silently.

Some people do not experience warning signs until a significant event occurs, such as a heart attack or stroke.

This is one of the reasons screening is so important. Checking things like cholesterol, blood pressure, and blood glucose can help identify risk early, even when you feel fine.

It is also why lifestyle habits matter, regardless of how you feel day to day.

Feeling “healthy” does not always reflect what is happening internally.


What Has Improved

1. Screening and Early Detection

We have far more tools now to assess risk.

Routine cholesterol testing is widely available. Blood pressure monitoring is common. 

Additional markers, such as C-reactive protein and coronary artery calcium scoring, can provide more insight in certain cases.

These screenings help identify risk earlier, sometimes before symptoms appear.

The earlier something is identified, the more opportunity there is to address it.

2. Medical Interventions

Treatment options have improved dramatically.

Procedures like bypass surgery and stent placement can restore blood flow. 

Medications such as statins, blood pressure medications, and newer therapies help manage risk factors more effectively.

These advances have played a major role in improving survival rates.

3. Changes in Smoking Rates

Smoking is a major risk factor for heart disease.

Over time, smoking rates have declined in the United States, which has contributed to improvements in cardiovascular health.

That said, tobacco use has not disappeared, and newer products continue to raise questions about long-term impact. We don’t know for sure if products like vapes and e-cigarettes have an impact on heart disease risk.

4. Understanding of Diet and Lifestyle

We know more now about how diet, physical activity, sleep, and stress affect heart health.

There is stronger evidence supporting dietary patterns that include:

  • More fruits and vegetables

  • Whole grains

  • Lean protein sources

  • Healthy fats

There is also more awareness of the role of physical activity and overall lifestyle in reducing risk.

What Has Not Improved as Much

Despite these advances, several factors continue to contribute to heart disease risk.

  • Rates of obesity remain high

  • Physical inactivity is still common

  • Dietary patterns often fall short of recommendations

  • Chronic conditions like diabetes and high blood pressure are widespread

In other words, while treatment has improved, prevention remains a challenge.

Why This Still Matters

It is easy to assume that heart disease is only a concern for certain people.

Older adults. People with a family history. Individuals who are overweight.

But risk is not always obvious.

Someone can be active, have a body weight within a certain range, and still have elevated cholesterol or other risk factors.

That is why screening is so important. 

Practical Steps to Reduce Risk

There is no single action that eliminates risk, but several steps can make a meaningful difference over time.

Know Your Numbers

Get routine screenings for:

  • Cholesterol

  • Blood pressure

  • Blood glucose

Talk with your healthcare provider about whether additional tests are appropriate.

Focus on Eating Patterns

Rather than focusing on individual foods, look at overall patterns.

Aim for meals that include a mix of:

  • Vegetables and fruits

  • Whole grains

  • Protein sources

  • Healthy fats

Stay Physically Active

Regular movement supports cardiovascular health.

This does not have to be extreme or structured. Consistency matters more than intensity.

Limit Tobacco and Alcohol

Avoid smoking. If you do smoke, quitting can significantly reduce risk.

Alcohol intake is another factor to consider. Reducing intake can support overall health.

Manage Stress and Sleep

These factors are often overlooked but play a role in heart health.

Chronic stress and poor sleep can contribute to changes in blood pressure, 

inflammation, and overall well-being.

Key Takeaways

So are we making progress?

Yes.

People are living longer. Survival rates have improved. We have better tools and more knowledge than ever before.

But heart disease remains the leading cause of death.

That tells us that while treatment has advanced, there is still work to be done in prevention and daily habits.

The goal is not just to respond to heart disease after it develops, but to reduce the likelihood of it developing in the first place.

And that starts with awareness, consistent habits, and regular screening.
