In last week’s blog, we took a look at the top 20 causes of chest pain and you can read the blog here:
The blog raised a couple of questions about one particular condition, Pulmonary Embolism (PE) as some of our followers had heard about it, but don’t really understand what it is and what it means. So, here’s our quick guide to all things PE - what it is, how it presents, what to look for, and most important of all, what to do if you suspect someone has a PE.
A pulmonary embolism is what happens when a blood clot blocks a blood vessel in your lungs. It can be life threatening if it’s not identified and treated quickly.
So that sounds pretty scary right?
But, our bodies have a pretty cool kind of early warning system. PEs are often (but not always) associated with another kind of blood clot, a Deep Vein Thrombosis or DVT.
A DVT is what happens when a blood clot forms in your leg, normally in the calf, then part of it detaches or dislodges and travels up to your lungs where it can cause a blockage, a PE.
The normal symptoms of a PE are:
- Difficulty breathing that starts very suddenly.
- Chest pain that’s worse when you breathe in - sometimes described as ‘pinpoint’ chest pain.
- Coughing up blood.
The normal symptoms of a DVT are:
- Symptoms are normally just in one leg.
- Pain in your leg - normally the calf area. Often described as ‘throbbing’.
- Heat around the painful area.
- Red or dark skin.
- Swelling and the leg feeling firm to touch.
For either a PE or DVT, you would need to go to hospital where you would most likely be given an injection of anticoagulant medication. Anticoagulants work in a variety of ways but simply stop any clots getting bigger and prevent new clots forming. Further tests such as scans and blood tests will be carried out.
If the tests carried out do confirm a PE, the anticoagulant injections will continue for at least 5 days, though the good news is that you may not need to stay in hospital for these. This stage of treatment is followed by a course of anticoagulant tablets for at least 3 months.
The other good news is that most people make a full recovery from a PE if it’s identified and treated early.
So what actually causes a PE or DVT?
There are lots of reasons that we might develop a DVT or PE, such as certain medical conditions that affect how the blood clots, dehydration, lack of movement and sitting for long periods, being confined to bed due to illness or injury, or due to pregnancy, trauma and surgery.
If you’re in hospital for any time following an injury, surgery or illness, the hospital will take steps to prevent a DVT or PE forming.
But I’m sure we’re all aware, if not fully up to speed, of the risks of developing a DVT through inactivity and not moving for a long period of time. If you’ve ever had surgery, you’ll remember the incredibly attractive socks that you’re made to wear afterwards!
This is really relevant in our industry because we all travel a lot and whether we use a car, bus or air travel, the risk of developing a DVT increases if we’re not moving much for long periods of time. The risk is particularly high for flights lasting 4 hours or more because blood flows more slowly and collects in the lower legs due to their position.
Other risk factors for a DVT are being over 60, being overweight, smoking, if you’ve had a DVT before, if you take the contraceptive pill or HRT, if you have cancer or heart failure. Varicose veins are also a warning sign.
Occasionally, a DVT forms spontaneously, for no apparent reason. Though be warned that there is strong evidence to support the theory that taller people are more at risk, particularly tall, young men!
