The image is a familiar one — a man hunched over, clutching his chest in pain. It’s the universal symbol for a heart attack. This chest pain, along with shortness of breath and pain radiating down the arm, are often considered the standard symptoms of a major cardiac event.

But there are more subtle symptoms that could also signal heart disease — a condition that includes heart attack, stroke and congestive heart failure.

Learn more about these five lesser-known signs and symptoms.

1. Sleep apnea

Obstructive sleep apnea, which almost always causes loud snoring, isn’t just a noisy habit that can keep your partner up at night, according to cardiologist Suman Kuppahally, MD. Snoring, whether it’s moderate or severe, can damage your heart as you struggle to breathe while sleeping.

“Sleep apnea causes a drop in oxygen in the blood several times during the night and that causes stress to the body,” Dr. Kuppahally says. “If left untreated, it can lead to cardiovascular problems such as high blood pressure, arrhythmias, heart attack and heart failure.”

If you snore, Kuppahally suggests consulting a sleep specialist right away to begin treatment.

2. Dizziness

Dizziness or lightheadedness may indicate that your brain isn’t getting enough blood, says Kuppahally, and it can be a subtle sign of a heart attack, especially in women, who often have atypical symptoms. Dizziness could also indicate an arrhythmia (abnormal heartbeat) or heart damage.

If you’re experiencing dizziness along with other heart symptoms, get to the ER as quickly as possible.

3. Sweating

A good workout isn’t the only thing that can cause you to break a sweat. If you start sweating suddenly — what’s often described as a “cold sweat”— while experiencing other symptoms, it could mean you’re having a heart attack.

“Sweating more than usual, without exertion, is a sign of stress to the body,” says Kuppahally. “If sweating is associated with discomfort in the chest, arm, neck or jaw or with shortness of breath, it should be taken seriously as a sign of coronary artery disease,” and you should get to the hospital immediately.

4. Fatigue or exhaustion

Most of us can feel worn out after a long day of dealing with work, kids and a mile-long to-do list. However, extreme, unexplained fatigue — the kind that leaves you too beat to climb a short flight of stairs or carry your groceries — could also be a warning sign of something more serious, like a heart attack or heart disease, especially in women.

One study published in the journal Circulation found that more than 70 percent of women experience unusual fatigue in the month leading up to their heart attacks. Some women ignored it as a symptom of a serious heart problem. And women who tried repeatedly to seek medical care often had this symptom misdiagnosed or dismissed by their physicians.

5. Erectile dysfunction

Heart disease and erectile dysfunction (ED) may both be caused by poor circulation, but problems in the bedroom usually occur first. This means that ED could be alerting you to current or future heart disease.

“ED and heart attack are both caused by plaque build-up in the arteries,” says Kuppahally. “Also, there’s a high prevalence of cardiovascular disease in patients with ED. And patients with heart failure or coronary artery disease frequently have other medical problems, such as diabetes and hypertension, which can cause ED.”

Other unusual signs and symptoms

Kuppahally also advises her patients to be on the lookout for a few other unfamiliar symptoms of heart disease:

  • Heart failure: leg swelling when upright, mild cough and shortness of breath while lying down
  • High blood pressure: undiagnosed sleep apnea and early morning headaches
  • Heart disease: depression and anxiety

To keep your ticker in tip-top shape, stick with a heart-healthy diet, get daily exercise, keep stress levels low and get adequate sleep.

And if you do think you’re experiencing a cardiac event, don’t wait. Call 911 immediately.
