When we hear the term heart attack, what comes to mind is usually an image of someone grabbing their chest and falling over. But what if your heart attack doesn’t include any of those symptoms? And what if you don’t even know it’s occurring? That’s a silent heart attack, and it’s more prevalent — and deadly — than most people realize.
At Pune Cardiology Clinic, we frequently encounter patients who did not even know they’d had a heart attack until the outcome of a routine test indicated heart muscle damage. In this blog, let’s learn what is a silent heart attack, how to recognize the signs, who is at risk, and when to visit a cardiologist.
What Is a Silent Heart Attack?
A silent heart attack, or a silent myocardial infarction (MI), is when one or more coronary arteries is blocked, limiting blood supply to the heart muscle. But unlike a common heart attack, the symptoms are extremely mild or even absent — and that makes it even more life-threatening.
Even though you may not feel severe symptoms, a silent heart attack can do substantial harm to your heart, making you more likely for heart failure and subsequent heart attacks.
Silent Heart Attack Signs
- Though the signs won’t be spectacular, there are a few warning signs you cannot ignore:
- Mild chest pain: You might experience pressure, tightness, or dullness, but not sharp pain.
- Unexplained tiredness: Getting extremely tired even after rest, particularly if it is a new activity or is getting progressively worse.
- Breathlessness: Finding it hard to breathe while engaging in daily activities or when lying flat.
- Sweats or dizziness: These may come on unexpectedly and without any obvious reason.
- Nausea, indigestion, or abdominal pain: Easily confused with acidity or gastric discomfort.
- Pain in the jaw, neck, back, or arms: These can be insidious but significant red flags in women.
These symptoms are not necessarily alarming individually, but in combination — or if they happen with great frequency they can indicate there is something more seriously wrong with your heart.
Who Is Most at Risk of Silent Heart Attacks?
Certain individuals are at a greater risk of silent heart attacks than others, including:
- Individuals with diabetes: High blood sugar levels can cause nerve damage, numbing the pain messages that would otherwise get your attention.
- Older people: With age, symptoms become more difficult to identify.
- Women: Women are more prone to atypical symptoms.
- Smokers and individuals with high blood pressure or cholesterol
- People with a family history of cardiac disease
- Individuals with an inactive lifestyle or unhealthy diet
If you belong to one or more than one of the above categories, you must be particularly careful and vigilant about heart health.
How Is a Silent Heart Attack Diagnosed?
Since symptoms are not evident or minimal, a silent heart attack usually is found accidentally, during a regular checkup or upon follow-up when a patient complains of fatigue or shortness of breath.
Some diagnostic tests that identify silent heart attacks are:
- Electrocardiogram (ECG or EKG) – Identifies electrical changes in the heart.
- Echocardiogram – Images heart function.
- Stress test (TMT) – Records how your heart behaves when subjected to physical stress.
- Blood tests – Can identify heart muscle damage.
- Coronary angiography – Can be prescribed if there is suspected blockage.
Why Silent Heart Attacks Are Dangerous
Since they may be missed, silent heart attacks are often not treated. This leaves the heart to keep working with weakened muscle, and this may lead to:
- Heart failure
- Abnormal heartbeat (arrhythmia)
- Greater risk of another, worse heart attack
- The sooner a silent heart attack is diagnosed, the greater your chances of avoiding further complications.
When to Visit a Cardiologist
