Hmm. After another stuck-in-bed weekend, I will try to summarize the Cheney lecture. Okay, bear with me.
Dr Cheney believes that part of ME / CFIDS is actually a heart disorder. His data shows that our hearts are anatomically intact but the left chamber is slow to fill and we are pumping as little as 60% of what we should be. The blood pressure and volume is not up to the job. Not even close. This has a huge negative cascading effect on the body - cells get hypoxic (starved of oxygen) and we feel as weak as someone with heart failure. When we try to over-ride our severe limitations, the body floods us with adrenalin to try and compensate. The effect is like trying to live on speed and the inevitable and frequent crashes are...well, inevitable. It's no wonder we have to stop - the system requires more fuel than we have to give it. The fall-into-bed factor is not 'fatigue'. It's the body's way of protecting itself for what is essentially an acute crisis of physiology.
The knock on effects of 'running on empty' are too many to mention. The blood chemistry is a mess with chemical alarm signals fighting it out with the body's attempts at compensation -which are counterproductive- eg inflammation, vasoconstriction, down regulation of hormones, etc...
And if we go to a cardiologist? Cheney says we'll most likely meet with ignorance and be sent home because our hearts are anatomically (although not functionally) normal. What caused this dysfunction in the first place? Place your money on a virus.
Treatments? None that work. That old chestnut. Cheney recommends always getting your feet up when possible (to increase blood flow to the upper body) and isotonic drinks (ie water with salt in). In the long term, he'd love to see if injecting stem cells into heart muscle could help. Jeeze. Who's going to be a guinea pig for that one? Another approach is a tablet with pig heart extracts in it. Ditto.
So there you have it. I've taken my blood pressure every morning this week and it's usually 94 over 50. Normal is 120 over 80. I feel like a semi-deflated balloon at a kids' party. Hell's bells. Hold on while I treat myself to another glass of salty water...

PS. Sometimmes I wish I didn't know things so I could just kid myself that I was a bit tired. Ah well, we need people like Cheney. All power to him.
