DEVASTATED parents are worried their daughter could die after she was diagnosed with a similar condition to the one that took her sister’s life.
Louise and Wayne Grant’s eldest daughter Dannielle (pictured) suffered from hypertrophic cardiomyopathy, which causes the wall of the heart to thicken, making it harder for the heart to pump blood around the body.
She went on to develop an irregular heart rhythm caused by arrhythmia and died after collapsing in a supermarket in 2008.
Now, in a cruel blow, the Grants have been told their daughter Mia, six, has hypertrophic cardiomyopathy and fear she could also develop arrhythmia, the condition which killed Dannielle.
Louise, of Fareham, said: ‘It’s heartbreaking to know we are going to go down the same path again.
‘We couldn’t believe it when we were told of the diagnosis and we don’t know what’s the cause of it.’
Six years ago, Louise was in a Co-op store in Highlands Road, with Dannielle and eldest son Carl.
The 38-year-old said: ‘It was the afternoon and we were on our way back from my mum’s. We stopped in the shop to get a couple of things and Dannielle and Carl were running around.
‘Then she stopped, looked at me, looked at her brother and then collapsed.
‘I was pregnant at the time, but I got down to give her mouth-to-mouth as I had been taught what to do.
‘I managed to revive her and the store had called for an ambulance.
‘But she was gone by the time they got her to Southampton General Hospital.’
Mia, who goes to St Columba Academy in Tewkesbury Avenue, Fareham, has a twin brother Troy.
He and the couple’s other children Carl, 18, Tyler, 15, Natasha, seven, and Charlie, four, do not have the condition.
‘Mia knows she’s got a heart problem,’ added Louise.
‘And she asks about Dannielle and asks if the same will happen to her.
‘But we are hoping Mia will prove them wrong.
‘We hope Mia will improve and show everyone how strong she is.’
The family still shop at the Co-op store where Dannielle collapsed and when staff heard of Mia’s diagnosis they decided to help.
Store manager Martin Sanger said: ‘We wanted to raise money for the family and Mia said she would like a Haven holiday.
‘The family would need £1,200, so we decided to raise £1,500 to help her.
‘The fundraising has been brilliant. A shopping trolley with £50 of goods was raffled for £400.
‘There is great community spirit here and people really got behind the various things we put on.’
Heart condition causes muscle wall to thicken
THE heart condition suffered by Dannielle and Mia causes the wall of the heart muscle to thicken.
The British Heart Foundation said that hypertrophic cardiomyopathy is an inherited disease and can be passed on through the family.
As the muscular wall of the heart – the myocardium – becomes thickened, it makes the heart muscle stiff.
There is no direct link to arrhythmia, the condition which led to Danielle’s death and it can be treated.
