Is It a Heart Attack or Angina?


WebMD Feature

It’s dramatic when someone has a heart attack on television or in the movies. But in real life, symptoms can be more subtle and difficult to identify. And because heart attack and angina symptoms are so similar, it may be hard to tell what's going on.

But knowing the differences -- and the reasons behind them -- can result in seeking treatment sooner, and living longer.

6 Symptoms of Women's Heart Attacks

When a heart attack strikes, it doesn’t always feel the same in women as it does in men. Women don't always get the same classic heart attack symptoms as men, such as crushing chest pain that radiates down one arm. Those heart attack symptoms can certainly happen to women, but  many experience vague or even “silent” symptoms that they may miss. These six heart attack symptoms are common in women: Chest pain or discomfort. Chest pain is the most common heart attack symptom, but some women...

Heart Attack Symptoms

About 715,000 Americans have a heart attack every year, according to the CDC. This happens when blood flow to the heart muscle is blocked or restricted, often by a clot in an artery. Deprived of oxygen, at worst the heart muscle dies; at best it’s damaged.

A 2008 study in the American Journal of Critical Care found chest pain was the most frequently reported heart attack symptom, and 61 percent of 256 participants said their symptoms were constant.

Chest pain is reported in various ways, including:

  • Discomfort
  • Pressure
  • Tightness
  • Burning
  • Fullness
  • Squeezing

“If you’ve not experienced it before, patients often aren’t sure what it is when it first comes on,” says Kristin Newby, MD, a cardiologist at the Duke Heart Center in Durham, NC.

Not All Symptoms the Same

The same study found women were about 8 years older than men when they developed heart trouble and were more likely to report a higher intensity of 5 other symptoms:

  • Indigestion
  • Palpitations
  • Nausea
  • Numbness in the hands
  • Unusual and overwhelming fatigue

The study found 21 percent of women and 10 percent of men experienced no symptoms at all. Less typical symptoms for both genders can include discomfort in the neck, arms, jaw, back, or stomach; shortness of breath; dizziness; or a cold sweat.

“Men and women may respond differently to the symptoms of a heart attack, particularly if the symptoms are vague. But if you have symptoms consistent with a heart attack, don’t wait at home. Go to the hospital,” says Alfred Sacchetti, MD, an emergency room physician and an American College of Emergency Physicians spokesman.

Recognizing Angina

Angina is your body's warning sign that something isn't right with your heart. Angina is temporary chest pain or pressure that happens when arteries that supply blood and oxygen to your heart become narrowed or blocked. That means your heart is getting less blood than your body needs to function properly. Angina is often triggered by strong emotion, physical exertion, hot and cold temperature extremes, or a heavy meal.

Symptoms can include:

  • Chest pressure or pain
  • Squeezing in the chest
  • A sense of fullness in the center of the chest
  • Pain or discomfort in the shoulder, arm, back, neck, or jaw

 

Two Types

There are two types of angina:

Stable angina: Your narrowed arteries cause pain, pressure, and other symptoms when you exert yourself. This may occur at regular times, and symptoms usually go away after you rest. If you're under a doctor's care, you may take nitroglycerin to ease the symptoms.
