Key Takeaways

Even if your blood pressure is in a healthy range, that does not mean you are automatically protected from having a heart attack.

View all takeaways

You keep an eye on your blood pressure, and it’s always in the healthy range. That means you’re safe from a heart attack, right? Not necessarily.

While hypertension (high blood pressure) is a well-known risk factor, it’s not the only one. You can have a heart attack even when your blood pressure is within a healthy range.

Learn more about hypertension, the connection between blood pressure and heart attack, and steps you can take to help protect your heart.

Normal Blood Pressure vs. High Blood Pressure: What’s the Difference?

A heart attack is one of the serious health problems associated with cardiovascular disease, a group of conditions that affect the heart and blood vessels. Each day, nearly 2,500 people in the United States die from cardiovascular disease.

Before we explore the link between blood pressure and heart attacks, let’s go over what normal and high blood pressure look like.

Blood pressure is measured in millimeters of mercury (mm Hg) and recorded with two numbers:

Systolic pressure — The pressure against artery walls when your heart beats
Diastolic pressure — The pressure against artery walls between beats

Here’s a breakdown of blood pressure categories:

The American Heart Association and the Centers for Disease Control and Prevention (CDC) report that nearly half of U.S. adults have high blood pressure. An estimated 44 percent of adults ages 30 to 79 worldwide with hypertension don’t know they have it, which means many aren’t diagnosed or treated.

The higher your blood pressure, the higher your risk of heart attack and stroke, even if you’re young. In one study, young adults with elevated blood pressure, stage 1 hypertension, or stage 2 hypertension before age 40 had a higher risk of cardiovascular events later in life than those with normal blood pressure.

Risk Factors for a Heart Attack With Normal Blood Pressure

Although high blood pressure is a major risk factor for heart attacks, it’s not the only one. You can have normal blood pressure and still have other risk factors for a heart attack.

Clogged Arteries

You may wonder, “Can you have normal blood pressure and clogged arteries?” Yes. Atherosclerosis is plaque buildup in the arteries, and it can develop for years without causing symptoms.

If plaque in a heart artery breaks open, a blood clot can block blood flow to the heart muscle. This is why normal blood pressure doesn’t always mean your arteries are clear.

High Cholesterol

High cholesterol is a key heart attack risk factor. When cholesterol levels are high, cholesterol can combine with other substances to form plaque inside your arteries. Over time, plaque buildup can narrow the arteries, slow blood flow, and increase the risk of a heart attack.

Smoking

Smoking cigarettes is a major risk factor for heart disease, and quitting can help reduce your risk. Smoking can harm the heart and blood vessels in many ways, including by temporarily raising blood pressure and heart rate and damaging blood vessels.

Diabetes

Diabetes also raises heart disease risk, even when blood sugar is well controlled. Managing blood sugar is still important because the risk is greater when blood sugar isn’t well controlled.

Body Weight

Body weight can be linked to heart disease risk, especially when a higher weight occurs along with high blood pressure, high cholesterol, or high blood sugar. Having more body fat around the waist is linked to a higher risk of heart disease and stroke.

Lack of Physical Activity

An inactive lifestyle is associated with several heart disease risk factors, including high blood pressure, high cholesterol, and high blood sugar levels. Regular exercise can help manage these risk factors.

Age and Family History

The risk of heart attack increases as you get older, although heart attacks can also occur in younger people.

Family history also matters. You’re more likely to develop heart disease if your parents had heart disease.

Stress

Chronic stress may contribute to high blood pressure and other heart disease risk factors.

Diet

A diet high in saturated fat, trans fat, or salt may raise the risk of heart disease. These foods can contribute to risk factors such as high blood pressure and high cholesterol.

Steps To Reduce Your Risk of a Heart Attack

Whether you have normal or high blood pressure, you can take steps to help reduce your risk of a heart attack.

Know Your Numbers

Regular checkups can help you track your blood pressure, cholesterol, blood sugar, and other health markers. You can also ask your healthcare provider whether you should monitor any of these numbers at home.

Adopt a Heart-Healthy Diet

Research shows that following a Mediterranean diet is linked to better heart health, including a lower risk of coronary heart disease, ischemic stroke, and total cardiovascular disease.

This type of diet focuses on fruits, vegetables, whole grains, lean proteins, and healthy fats. Limit saturated fats, trans fats, and sodium (salt).

Stay Active

Adults should aim for at least 150 minutes a week of moderate-intensity activity, such as brisk walking, or 75 minutes of vigorous activity, such as jogging. Talk with your healthcare provider about which activities and intensity levels are safe for you.

Quit Smoking

If you smoke, quitting can greatly reduce your risk of heart disease. Ask your healthcare provider about tools and support that can help you quit.

Manage Stress

Find healthy ways to cope with stress, such as meditation, deep breathing, or yoga. Talking with a therapist or other mental health professional may also help.

Limit Alcohol

If you drink alcohol, the American Heart Association recommends no more than two drinks per day for men or one drink per day for women.

Take Medications as Prescribed

If you take medication for high blood pressure, high cholesterol, diabetes, or another heart risk factor, take it exactly as prescribed. If side effects or costs make this difficult, tell your healthcare provider.

Get Enough Sleep

Sleep is an important part of heart health. Most adults should aim for seven to nine hours each night. If you regularly have trouble getting enough sleep or getting good-quality sleep, talk with your healthcare provider.

How Blood Pressure Changes During a Heart Attack

Does blood pressure change during a heart attack? It can, but a blood pressure reading can’t confirm or rule out a heart attack. During a heart attack, reduced blood flow to part of the heart can damage the heart muscle and may affect how well the heart pumps blood.

In severe cases, cardiogenic shock can happen when the heart can’t send enough blood to the body.

Don’t use a blood pressure reading to decide whether symptoms are serious. Call 911 if you have heart attack warning signs, such as chest discomfort, shortness of breath, a cold sweat, nausea, rapid or irregular heartbeat, unusual tiredness, or lightheadedness.

Talk With Your Doctor

Normal blood pressure is a good sign, but your overall heart health depends on many factors, including cholesterol, blood sugar, daily habits, and family history.

If you’re concerned about your risk, talk with your healthcare provider. They can help you understand your risk factors and make a plan that fits your health needs.
