A Silent Heart Attack: What You Need to Know
When people think of a heart attack, they tend to picture sudden, severe chest pain, shortness of breath, or someone clutching their chest in distress. But not all heart attacks look like this.
In fact, some happen quietly, without the dramatic symptoms we associate with cardiac emergencies. These are known as silent heart attacks and can be just as dangerous to your health.
Our team at Premier Cardiology Consultants delivers top-quality care from three convenient locations in New York. Our goal is to partner with you in living the healthiest life possible by diagnosing, treating, and preventing issues that affect your heart.
Here’s what our team wants you to know about silent heart attacks and why we take them so seriously.
What is a silent heart attack?
Like any heart attack, a “silent” version occurs when blood flow to part of the heart muscle is blocked. However, because the symptoms are milder than expected, temporary, or mistaken for something else, like heartburn, the person is not likely to seek medical help.
Even though they go unnoticed, silent heart attacks cause real damage to the heart muscle. Over time, this damage can increase your risk of heart failure, arrhythmias, and future heart attacks.
Common signs you might miss
The symptoms of a silent heart attack are often subtle and may include:
- Mild discomfort or pressure in the chest (not always severe pain)
- Shortness of breath during routine activities
- Fatigue or feeling unusually tired
- Heartburn or nausea
- Pain in your jaw, arms, or upper back between the shoulder blades
- Lightheadedness or mild dizziness
Because these symptoms can be mistaken for indigestion, a muscle strain, or the flu, many people ignore them. Often, silent heart attacks are discovered later during tests for another condition or on an electrocardiogram (EKG).
Who is most at risk for a silent heart attack?
Anyone can have a silent heart attack, but women, older adults, and people with diabetes are especially likely to experience silent heart attacks.
Other risk factors include:
- High blood pressure
- High cholesterol
- Smoking
- Obesity
- Family history of heart disease
- Sedentary lifestyle
People with diabetes are particularly vulnerable because nerve damage (neuropathy) can dull pain sensations, making symptoms easier to miss.
Diagnosing silent heart attacks
Since the signs are easy to overlook, silent heart attacks are often discovered incidentally. Your cardiologist might find evidence of one through:
- An EKG (electrocardiogram) showing changes in heart rhythm that suggest past damage
- An echocardiogram that reveals areas of the heart with reduced movement
- Blood tests that detect cardiac enzymes that indicate heart muscle injury
- Stress tests or cardiac imaging that assess how well your heart is functioning
If your doctor suspects a silent heart attack, early detection is key to preventing further complications.
Treatment and prevention
If you’ve had a silent heart attack, treatment focuses on protecting your heart and preventing another one. Your cardiologist may recommend:
- Medications to manage blood pressure, cholesterol, or blood clots
- Lifestyle changes, such as a heart-healthy diet, regular exercise, and quitting smoking
- Regular checkups to monitor heart function and adjust treatment
- Cardiac procedures such as stenting
Prevention is equally important. We recommend scheduling routine heart screenings, especially if you have risk factors. Pay attention to your body — even mild symptoms can be a warning sign.
If you’ve been feeling unusually fatigued, short of breath, or have unexplained discomfort in your chest, don’t ignore it. A cardiologist can perform simple, noninvasive tests to evaluate your heart health and ensure nothing serious is being overlooked.
