There are many PH patients who have developed PH because of undiscovered blood clots in their lungs and for them the importance of an INR test is paramount. Many of these PH patients are suitable for a Pulmonary Endarterectomy operation, which is a major high risk operation to clear the blood clots, but if the operation is successful it can lead to improved quality of life and increased life expectancy. Papworth Hospital in Cambridgeshire is currently the only centre in the UK that can offer this surgery. Recently this operation was featured on the 'One Show'. You can find this on YouTube, just google Pulmonary Endarterectomy and the link will come up - the link would not work in my blog unfortunately. It does not always return life to normal though for some patients and they still have PH through residual and distant clots and have to have the general and specialist PH drugs and warfarin to help them. There is more about Pulmonary Hypertension caused by blood clots and the treatment available on the PHA UK website below:
Some of my friends have gone to the expense of buying their own INR machines to save them the grind and inconvenience of extra hospital visits, but these are expensive and still need to be used in conjunction with your local warfarin clinic and GP.
I would be interested to know what others have to endure with their regular INR checks and whether your stories are good ones like mine or bad like my dad's!
