How to Tell if Someone Is Having a Heart Attack

Five heart attack symptoms to watch for and how to respond
emergency

Quick summary

Although you're probably familiar with the classic heart attack scenario from movies and TV, most people don't just clutch their chests and fall to the ground. Heart attacks usually start slowly, with mild pain or discomfort, or even more subtle flu-like symptoms. Heart attack symptoms can be subtle, and it's not always easy to tell what's happening. But if someone is having a heart attack, every second counts: There's a limited window of time before heart muscle is permanently damaged. Delaying treatment also increases the risk of sudden death from an irregular heart rhythm.

To give someone the best possible chance of recovery, it's wise to familiarize yourself with the warning signs of a heart attack. Remember that all heart attacks are not equal: Even if you've seen someone have a heart attack before, a second heart attack or a heart attack in someone else might not have the same symptoms.

Pay special attention to heart attack symptoms in women

Although many people mistakenly believe that cardiovascular disease isn't a problem for women, it's still a leading cause of death. Unfortunately, women tend to have different heart attack symptoms than men, so heart disease may go unrecognized until it's too late. In a study of 515 women who'd had heart attacks, the most frequently reported symptoms were unusual fatigue, sleep disturbances, shortness of breath, indigestion, and anxiety. Less than one-third reported any chest discomfort.

How to respond if you see signs of a heart attack

In general, it's best to call 911 if you have any reason to suspect that someone is having a heart attack. Waiting even an hour or two may limit treatment options and reduce the chance of a full recovery. It's common for someone having a heart attack to downplay the situation because he or she is embarrassed and doesn't want to cause a scene. Take charge and call for help even if the person tries to talk you out of it. Don't wait to see if heart attack symptoms go away -- and call even if the symptoms do disappear or come and go. If it turns out to be something less serious than a heart attack, at least you'll have some peace of mind.

Bear in mind that not all of the following warning signs occur in every heart attack.

The five signs of heart attack

Heart attack sign #1: Chest discomfort or pain

The most commonly reported heart attack symptom among men is chest discomfort, often described as a heaviness, tightness, or even a burning sensation. The feeling usually starts in the center of the chest and may or may not radiate to other areas of the body. It may go away and then come back, or it may be continuous.

If you're aware of someone experiencing any persistent chest discomfort, call 911 right away. Even if it's angina rather than a full-blown heart attack, he needs to see a doctor.

Heart attack sign #2: Discomfort in other parts of the body

Sometimes the pain of a heart attack doesn't occur in the chest. Instead, he or she might complain of discomfort or pain in one or both arms or back, neck, jaw, or even stomach. Women are more likely than men to experience pain in the jaw or back during an attack. It can be hard to tell if the discomfort is related to a heart attack or something else entirely, but if the pain came on suddenly or the person is experiencing another symptom as well, call 911.

Heart attack sign #3: Shortness of breath

It's common to be a little short of breath after exertion. But if someone is having difficulty breathing when at rest, it's cause for concern. Have him stop whatever he's doing and sit or lie down. If the shortness of breath persists for more than two minutes, call 911.

Heart attack sign #4: Nausea, sweating, pallor, or clamminess

These more subtle signs of heart attack can sometimes be mistaken for the flu. Women are more likely than men to report flu-like symptoms. If these symptoms come on suddenly or are accompanied by other signs of a heart attack, call 911.

Heart attack sign #5: A general feeling of extreme weakness or fatigue

As with nausea and sweating, weakness or fatigue can be symptoms of other conditions. But if the weakness or tiredness comes on suddenly -- espe cially if it's a woman experiencing it -- call 911.

When I had my heart attack... the only thing that I had was a sense of doom... I knew that if I let my husband leave for work I would be dead when he came home. There was no pain. I had not lay down to sleep all night. I now know I should have called for an ambulance..... rather then being taken to the hospital by car. I might have died becauses I did not want to bother anybody. After the surgery I remember waking up and being so happy to be alive.

Interesting article. I wish I'd seen it before I went down in the road with a heart attack while walking my dog. I had been experiencing extreme fatigue for several days prior to the event, and one night about four days prior to this, severe jaw pain woke me up. I ended up in the ER, got stitches for cuts on my head, and spent several days in icu.

Am now wearing a Zoll Life Vest in case of sudden cardiac arrest; have several more weeks to go wearing this, and am climbing the walls because I'm not to drive nor workout in the gym. The ironic thing about this is that I had my annual checkup two weeks previously. Great health - I worked out three mornings a week, walked the dog twice a day, ate a heart-healthy diet, took no medications. Hide

My husband passed away on April 27; he died while we were shopping at Walmart. The only words he said: I don't feel good and he started collapsing in my arms. What I would like to know why his eyes were so wide open and he couldn't move his eyes while I could see his stomach moving a little bit. The doctors said that he died of a massive heart attach. It seems he tried to say something but he could talk no more at that point. My husband passed away on April 27; he died while we were shopping at Walmart.

Two years ago, at 63, I had heart failure due to unknown CAD. Although I was somewhat overweight, I had exercised every morning before work and had always been in good health. Or so I thought! Then, one cold January morning, I experienced EIGHT heart failures in less than TWO DAYS while commuting back and forth to work. Each time it happened, my chest felt like an elephant was stomping on it, I had severe pain in my left clavicle, I felt nauseous and disoriented, and my legs felt extremely weak, giving out from under me as I slid to the ground against any support I could find. After each episode, which would last about 4-5 minutes, I'd get up, gather my belongings and walk about another 25 feet when it would happen again. (By the way, nobody stopped to ask if I needed help!) It happened twice before I got to the train station and again after I reached my destination. I still continued my commute -- both days -- without asking or calling for help, as I didn't relate the symptoms to heart trouble; rather, I thought my shortness of breath was due to my lack of exercising for the past couple of months! When I finally went to my doctor on the second day, he ran an EKG and sent me by ambulance directly to the emergency room. Upon performing an angiogram, it showed that my LAD was 97% blocked on top and 85% below, so two stents were placed. Then 6 weeks later, the doctor had to stent both the left and right arteries as well. Needless to say, the doctor was shocked that I survived to tell my story. Hide

Actually, I have had a heart attack in 2006, another 3months later due to the stents collapsing. I had pericadial/lung cancer, adenocarcinoma. 38 weeks of radiation therapy. The quantity of radiation therapy is what shrunk the anterior arteries causing the heart attacks. Having one lung, the left lung, is hard enough, but when every breath gets too difficult, that is when I start worrying. Always take good care of yourself and your heart. DON'T SMOKE!!! Smoking can cause heart attacks too. Actually, I have had a heart attack in 2006, another 3months later due to the stents collapsing.
