‘Silent heart attack’ warning for women as four signs reveal you could be having one without realising

Around 100,000 hospital admissions each year in the UK are due to heart attacks, according to the British Heart Foundation - a figure which works out to be a shocking 290 admissions each day or one every five minutes.

And, as we know, one thing that can help lower such a figure is raising awareness on heart attacks, namely the symptoms of the medical emergency and how different people can experience them differently.

While many would assume that they'd feel symptoms such as chest pain, shortness of breath and pain in the arms when having a heart attack, it turns out that this isn't always the case as women have now been issued a warning over having heart attack without realising it - something which is referred to as a 'silent heart attack'.

What is a silent heart attack?

It is still a heart attack which, as the NHS states, is a medical emergency where the blood supply to the heart suddenly becomes blocked.

But a silent one comes with either mild symptoms, ones that people don’t usually connect to a heart attack, or - even more frighteningly so - none at all.

Yep, this means that some people can have a heart attack without even knowing.

Causes of a silent heart attack

The Cleveland Clinic explains that they are commonly caused by coronary artery disease, which is when plaque that contains cholesterol collects in your coronary arteries, limiting how much blood can get to your heart.

"When a blood clot forms on the plaque, it can keep oxygen-rich blood from getting through at all," the site states. "Without quick treatment to restore blood flow, heart muscle can die."

While studies have differed, silent heart attacks are suggested to be more common in women than in men, and it is believed that some women may be more likely to dismiss the symptoms as stress or anxiety.

Risk factors for women are the same as a regular heart attack, and include:

• Diabetes

• Smoking
• Family history of heart disease

How can you avoid a silent heart attack?

The American Heart Association's Go Red for Women has suggested some lifestyle tips that can be preventive in having a heart attack or a silent one:

• Be aware of your blood pressure and cholesterol numbers
• Exercise regularly
• Quit or avoid smoking
• Keep blood sugar under control if you're diabetic
• Always seek healthcare advice if you feel something isn't right

If you experience any of these symptoms and feel you're having a heart attack, call 999 immediately. And if you feel you're having a silent heart attack, as Go Red for Women urge, be sure to make it clear that you think you may be having a heart attack and not an anxiety attack - advocate for yourself or, if you can, bring someone who will advocate for you.
