Heart attack symptoms: Three unexpected warning signs of silent heart attack when waking up

In the movies, heart attacks always happen in the most dramatic fashion, with the patient crushing under severe pain in their chest, at the site of their heart. But in reality, a heart attack could happen with not-so-evident signs. This makes it all the more risky, for people may not be able to identify the deadly condition, and dismiss it as something less urgent or serious.

There are certain tell-tale signs of this silent heart attack, which can especially happen in the morning. Knowing these and paying attention to them if they happen is essential for immediate treatment. Here are some of these signs in detail:

If your arteries are clogged, your heart will have to work harder with more pressure to push the blood throughout your body. When such extra exertion happens, your body may sweat more to keep your body temperature down. In case you experience cold sweats or clammy skin upon waking up in the morning or in the middle of the night, you should consult your doctor.

You may also experience mild indigestion and other gastrointestinal problems before having a heart attack. It is important to not take these for granted by popping antacids, and seek medical attention. Older people, who are typically more prone to digestive issues, are more likely to dismiss these signs of heart attack as heartburn or any other food-related problem.

Nausea may also be accompanied by stomach pain. Some people may even experience vomiting. When you vomit, the contents of your stomach are forced up through the food pipe and out of the mouth. Vomiting is not healthy and you should see your doctor.

People may often dismiss these signs as symptoms of flu. However, even if similar, pay attention to your body and you may feel that this does not feel flu-like as before.

Some of the most common signs of heart attack are chest pain or discomfort that suddenly occurs and doesn’t go away. This can feel like a pressure or tightness or heaviness in your chest. Some people also experience pain that can spread to their left arm, right arm, neck, jaw, back or stomach. Feeling light-headed or short of breath may also be signs of a heart attack.

When experiencing a heart attack, the first thing you must do is call immediately for an ambulance. This is an important step and should be followed even if you are not completely sure whether your symptoms imply a heart attack. Regardless, immediate medical attention is crucial.

“It's important that you rest while you wait for an ambulance, to avoid unnecessary strain on your heart," explains the NHS UK.

If aspirin is available (and you are not allergic to it), slowly chew and then swallow an adult-size tablet (300mg) while you wait for the ambulance, advises the health body. Aspirin helps to thin the blood and improve the blood flow to your heart.
