Common heart attack signs and symptoms include:

  • Pressure, tightness, pain, or a squeezing or aching sensation in your chest or arms that may spread to your neck, jaw or back
  • Nausea, indigestion, heartburn or abdominal pain
  • Shortness of breath
  • Cold sweat
  • Fatigue
  • Lightheadedness or sudden dizziness

Not all people who have heart attacks have the same symptoms or have the same severity of symptoms. Some people have mild pain; others have more severe pain. Some people have no symptoms; for others, the first sign may be sudden cardiac arrest. However, the more signs and symptoms you have, the greater the likelihood you're having a heart attack.

Some heart attacks strike suddenly, but many people have warning signs and symptoms hours, days or weeks in advance. The earliest warning might be recurrent chest pain or pressure (angina) that's triggered by exertion and relieved by rest. Angina is caused by a temporary decrease in blood flow to the heart.

Funny thing about a heart attack is that I had no symptoms the only symptom I had was I thought it was heatstroke and I was severely thirsty tired couldn't stop the thirst but I was use to feeling tired I did concrete work so feeling tired thirsty and breathing hard was all part of the job there for I thought heat stroke it wasn't til I got home and hit the air conditioning that I realized something was very wrong went to the ER and found out I had a heart attack therefore I got two stents in my heart end of story
That's exactly the same that has ever happened to my husband! 6 years ago, my husband was diagnosed with heart attack. It was in the midsummer. My husband was a engineer and at that time he was in charge of the construction of the stadium. However, after two-month intense outdoor work, he fell ill. For a whole week, he had been feeling extremely tired, thirsty and a strong heartbeat even if it was a slight gesture. No more obvious signs implying the possibility of catching a heart attack. My husband and I just took it as the symptom of heatstroke. However, things got worse several days later. It was then that I realized it was something big and we had to go to the hospital for further examination. Thanks to the doctor, my husband felt much better after one-year consistant treatment. I hope you'll be better off someday in the future.
Waking up in the middle.of the nite with severe heart burn & going away just fast as it appeared.  Shortness of breath * chest discomfort.
Did it just happen once?  It could be unstable angina. See a cardiologist and get an EKG and CT coronary angiogram.
Does your heart pound every night or not? You may need to see a doctor for proper diagnosis and treatment. But if it happens occasionally, it may be due to:

1. Nightmares or Night Terrors
2. Emotional Triggers
3. Hormonal Changes in Period, Pregnancy and Menopause
4. Certain Medications or Substance
5. Low Blood Pressure
6. Low Blood Sugar Level
7. Heart Disease
8. Other Health Conditions

If you experience heart racing at night that lasts only a few seconds, you may not need medical evaluation. However, if you have frequent palpitations or a medical problem that may cause your palpitations to worsen, call your doctor. You may need further tests like heart-monitoring tests to see what is causing your problem.

Seek emergency care if you also experience:
Chest pain or discomfort
Severe dizziness
Sudden shortness of breath
