Taking a Look at Some Early Signs of a Heart Attack

When a heart attack strikes, every minute matters. The sooner a heart attack patient seeks emergency care at a heart hospital , the better the outcome is likely to be. This is because when blood flow to the heart is obstructed, the heart muscle begins to die. The body replaces damaged tissue with scar tissue, which cannot function properly like normal tissue. Irreversible heart damage causes long-term health problems, but patients can minimize heart damage by calling 911 right away. The emergency care team of Sunrise Hospital and Medical Center encourages our neighbors to become familiar with the early warning signs of myocardial infarction.

Rapid Heartbeat

Some symptoms of a heart attack may develop weeks or even months before the heart attack itself occurs. These can include a rapid or irregular heartbeat. Sometimes, a rapid heartbeat may indicate ventricular tachycardia, which is defined as at least three irregular heartbeats in a row and a pulse rate of more than 100 beats per minute. It may occur before or after a heart attack and it can cause sudden death. Cardiologists advise that patients call 911 immediately for emergency care if they suspect they may have ventricular tachycardia.

Gastrointestinal Distress

It’s easy to mistake some signs of a heart attack as being benign symptoms, especially when they are gastrointestinal symptoms. These can include indigestion, nausea, and stomach pain with no apparent cause.


Exhaustion or fatigue is another sign of an impending heart attack that may occur long before the cardiac event. Fatigue goes well beyond ordinary tiredness. The fatigue associated with a heart attack may be described as being similar to fatigue caused by mononucleosis. In other words, it can feel “crushing” or disabling.

Even if you aren’t sure whether your symptoms are caused by a heart attack, cardiologists generally agree that it’s best to seek emergency care just in case you do have a life-threatening condition. Please call 911 immediately if you think you could be suffering a heart attack. Otherwise, you can get in touch with a registered nurse at Sunrise Hospital and Medical Center—a heart hospital in Las Vegas—by calling (702) 233-5300.
