A heart attack, also known as a myocardial infarction, happens when blood flow to part of the heart is blocked. While it may seem like a sudden and unexpected event, many heart attacks are preceded by early warning signs. Recognizing these symptoms and seeking help right away can save your life and prevent long-term damage to the heart.
At Epic Cardiology, we want you to feel confident recognizing when something may be wrong and knowing when to act. We provide care at our clinics in Chino, Pomona, San Dimas, Sherman Oaks, Lynwood, and Inglewood, helping people across Los Angeles protect their heart health.
What Is A Heart Attack?
A heart attack occurs when a blockage in one or more coronary arteries prevents oxygen-rich blood from reaching the heart muscle. Without prompt treatment, the heart tissue begins to die. While the image of a sudden collapse is common in movies and TV, real-life symptoms are often more subtle and can build over time.
Not everyone experiences the same warning signs, and some people, especially women, older adults, and people with diabetes, may have symptoms that are less obvious. That’s why it’s important to understand the early clues your body may give you.
Common Early Warning Signs
These symptoms may begin hours, days, or even weeks before a heart attack occurs. They might come and go or seem mild at first, but they should not be ignored.
Chest Discomfort
- Pressure, squeezing, fullness, or pain in the center or left side of the chest
- May last more than a few minutes or go away and return
Shortness of Breath
- Difficulty breathing with or without chest pain
- May occur during activity or at rest
Unexplained Fatigue
- Feeling unusually tired even after light activity
- A common early symptom in women
Pain in the Upper Body
- Discomfort in the neck, jaw, shoulder, back, or arms
- May be steady or come and go
Nausea or Lightheadedness
- Feeling dizzy or faint
- Sometimes accompanied by a cold sweat
Indigestion or Heartburn-like Sensations
- Some people experience heart attack symptoms that feel like stomach discomfort
It’s important to remember that not all heart attacks begin with dramatic chest pain. Any of these symptoms, especially when they are new or unexplained, should prompt you to seek medical attention.
Why Should You Pay Attention to These Symptoms?
These early signs are your body’s way of warning you that your heart may not be getting enough oxygen. Acting early can make a life-saving difference. The longer the heart goes without proper blood flow, the more damage occurs. Prompt treatment can open the blocked artery, restore circulation, and help preserve heart function.
Benefits of Early Detection
- Increased Survival Rate – Prompt treatment reduces the risk of serious complications and death
- Less Heart Damage – Early care minimizes the extent of injury to the heart muscle
- Fewer Long-Term Complications – Quick response may reduce the chance of heart failure or other chronic heart issues
- Faster Recovery – Patients treated early often return to normal activity sooner
- Peace of Mind – Knowing what to look for can help you respond confidently and quickly
What Should You Do If You Notice Symptoms?
- Call 911 immediately – Do not try to drive yourself or wait to see if it improves
- Chew an aspirin if advised by a provider – This may help slow clot formation
- Stay calm and still – Physical strain can make the situation worse
Even if you’re not sure it’s a heart attack, it’s better to be cautious. Providers would rather evaluate a false alarm than miss a life-threatening condition.
How Can You Lower Your Risk?
While not all heart attacks are preventable, you can significantly lower your risk by:
- Managing high blood pressure, cholesterol, and diabetes
- Quitting smoking and avoiding tobacco
- Eating a heart-healthy diet
- Staying physically active
- Seeing your cardiologist for routine checkups and screenings
