A staggering half of all heart attacks are silent. Did you know that in 2006 an amazing 89,400 New Zealanders suffered a heart attack and were hospitalised because of it? And over half of those who have previously suffered one or more heart attacks will have another one? What you almost certainly may not be aware of is that 25 percent of ALL heart attacks happen “silently,” without clear or obvious symptoms, regardless what Western developed country you live in. Even when symptoms do occur, they can be so mild or vague, most people don’t even realise it’s heart-related (unless they are made aware). Four things in particular are the most sinister signs of a silent heart attack.
Many who experience a silent heart attack do not even make it to the emergency room. Studies indicate around 1 out of every 2 women who suffer a heart attack feel no chest pain. They’re known as silent heart attacks. They’re often misdiagnosed or go untreated making them twice as deadly.
Incredible, but over half of women who experience a heart attack have “silent” heart attacks and may not even be aware they have had a heart attack. This is why regular blood pressure checks and blood tests are important, especially for women who are post-menopausal. do you know the impending signs and symptoms of a silent heart attack? Many think they could be having indigestion or an “upset stomach” with a heart attack, pain in the left shoulder, jaw or arm – and it can be very subtle (you may think you have muscle strain. What about profuse sweating? These are all potential tell tale signs and symptoms. Worth checking out, it’s your life.

- Cardiovascular disease (heart, stroke and blood vessel disease) is still the leading cause of death in NZ, accounting for 40% of deaths annually.

- It is estimated that 5,000 people in NZ die prematurely from smoking each year – this equates to around 12 people a day dying from smoking. 
Timing Is Important
Timing is the most critical factor for heart attack survival. There are plenty of statistics show a clear link between the delay in treatment and disability or death — the amount of time that elapses between the first sign of symptoms and receiving critical care.
4 Signs And Symptoms Of A Heart Attack
That’s why knowing what to look for in terms of symptoms is critical, especially when they’re the kind that most people don’t think to associate with a heart attack. Here are the 4 key things to be on the lookout for:
- Chest discomfort. Most heart attacks involve discomfort in the center of the chest that lasts for more than a few minutes, or goes away and comes back. The discomfort can feel like uncomfortable pressure, squeezing, fullness, or pain.
- Discomfort in other areas of the upper body. Can include pain or discomfort in one or both arms, the back, neck, jaw, or stomach.
- Shortness of breath. Often comes along with chest discomfort. But it also can occur before chest discomfort.
- Other symptoms. May include breaking out in a cold sweat, nausea, or light-headedness.
