Is anybody noticing how sadly quiet it is without Wynne's contribution to this thread?

What??? Do you think she mightn't be a fan of flat racing, let alone over the sticks....

My retort always is: Have you ever tried to get a horse through an open gate when it doesn't want to go or onto a float?

Have you ever seen a horse at the track not take off like a rocket at the first chance they get?.....

Yes I have, in answer to your question.

Most horses love galloping and racing for sure and many will give their all to their last breath. I know very well that the racing authorities are making enormous efforts and investment to make racing safer, I am just making the point in principle that the fact that a horse enjoys galloping and gets high on adrenaline during a race is neither here nor there in terms of our moral responsibility to the welfare of that horse.

A "wind op" so the horse could function as an athlete.....!

and yet poor old Lance Armstrong was hung, drawn and quartered for using a bit of EPO!

I recently performed a staphylectomy on a pug...... but I don't rate its chances against those greyhounds.

I can't bear the horse-racing / greyhound-racing worlds. Don't even feel the need to justify myself.

Archbold out.

I also had exactly that thought yesterday, she would have most definitely have been saying how tragic it was.

Yes. She is much missed. I certainly find myself thinking 'what would Wynne say?'

Wren,

What do you you mean by 'pre-season wind op'?

RE: Sudden death in racehoses

Anthony Dennison — Tue, 31 Jan 2017 09:32:29 GMT

I think the pressure changes within a horses thoracic cavity when they are running hard and seriously breathing, along with the shockwaves coming up from the leg, would put all sorts of stresses on the intrathoracic vessels

I think generally a spontaneous tear in these circumstances, although I have to admit I've never done histo on any that I've PM'd.

RE: Sudden death in racehoses

Anthony Todd — Tue, 31 Jan 2017 09:05:40 GMT

Is the vessel, wherever it is, normal on histo or has it been damaged prior to rupture?

Do horses get aneurysms?

[just asking]

I seem to remember there is a similar syndrome in coursing greyhounds where they sort of collapse after a chase??

PM report^^

There has been a huge uproar about this - obviously as it happened so publically and in such dramatic circumstances (for those who weren't watching he effectively outjumped, outfought and outran the much fancied, much-hyped, supposedly unbeatable favourite Thistlecrack to beat him virtually on the line, before collapsing and dying on his way back to the winners' enclosure).

The problem is that after both his Grand National and Hennessey wins Many Clouds suffered episodes of hyperthermia/exercise related ataxia. So everyone assumed this was also the case on Saturday and were quick to jump up and down and shout that he should have been retired from racing after the Grand National. However his jockey (who has ridden him in every one of his races) has adamantly maintained that what happened on Sunday was totally different - he did not feel 'cooked', he had come back down to a walk, ears pricked and was starting to recover from the race - unlike the previous episodes. The PM bears this out - there was no relationship to what had prevsiouly happened, and no way of predicting what was going to happen on Saturday.

This was arguably one of the fittest horses in the country, who had had a successful pre-season wind op and was reportedly on the form of his life - borne out by the race result. Sure, it was a tough race, but pretty much every winner on Saturday ran a tough race. It bugs me that the internet has been full of people jumping to conclusions before the PM was even performed. But I guess that's par for the course.

Just been released that Many Clouds died from pulmonary haemorrhage if that helps (horse and hound website).

Pulmonary haemorrhage

21 (13.0%, 7.8–18.1%)

16 (72.7%, 54.1–91.3%)

11 (30.6%, 15.5–45.6%)

From the paper I cited, they did it in Oz, Japan, Penn etc. so there's three sites. Strange range of results??

Pulmonary haemorrhage would have been top of my list

Somewhere from the dim and distant past is saying 'exertional rhabdomyolisis.'

Well my "aortic rupture" was way down the list!!!

Aortic rupture, which is anecdotally thought to be a common cause of exercise-related sudden death in horses, occurred in only 1% (2/268) of cases.

Hands up! I know nothing about horses but I'm pretty sure that an arrhythmia can cause sudden death. I know AF is not uncommon in horses.

Should have just asked Dr Google....

Cardiac arrhythmias?

They wouldn't cause sudden death though??
