Still Game stars Mark Cox and Jane McGarry are backing a bid by a Scottish hospital to achieve a heart-warming world record.

The comedy duo, who play Tam and Isa in the hit show, kick-started a campaign by the Golden Jubilee in Clydebank to create the largest online photo album of people making a heart-shaped hand gesture.

The Guinness World Record attempt has been launched to mark the 25th anniversary of Scotland's first heart transplant.

Over the last quarter of a century, more than 350 heart transplants have been carried out but medics are hoping the public can help them transform the lives of more Scots families.

The public, politicians and Scottish celebrities to post a selfie and share it on the hospital's Facebook and Twitter pages using the hashtag #Heart25.

The campaign is also asking participants to make a £1 donation. All the money raised will be used to help develop new treatments to help patients with heart failure, which affects around 45,000 Scots.

The only cure for advanced heart failure is a transplant but there is a national shortage of donors.

The Golden Jubilee is home to the Scottish National Advanced Heart Failure Service and is the only site in Scotland to carry out heart transplants. The life-saving surgery was previously carried out at the country's Heart and Lung Transplant Unit, launched in 1991 at Glasgow's Royal Infirmary. The unit welcomed its first patient, Charles Carylon, that year.

Mark Cox said: “I’m delighted to support the #Heart25 campaign, celebrating 25 years of heart transplantation in Scotland.

“While there have been some incredible advancements in treatment and technology for these patients, there is still no cure for heart failure other than a heart transplant.

“Every penny raised from #Heart25 will be used by the team at the Golden Jubilee to improve each patient’s quality of life and find new ways to treat advanced heart failure in Scotland.”

Jane McGarry, who stars as “nosey neighbour” Isa, added: “The #Heart25 Campaign is also raising funds to treat the thousands of patients across the country who are left unable to carry out the day to day things which we take for granted.

“Please, show your support for the campaign by snapping a picture of your ‘heart shaped hand gesture’, sharing it on the Golden Jubilee’s Facebook or Twitter with #Heart25, and donate to the service.”

Jill Young, Chief Executive of the Golden Jubilee National Hospital, said: “We are thrilled that Mark and Jane have volunteered to help us spread the word and cannot thank them enough for supporting the #Heart25 Campaign.

“Heart failure affects around 45,000 people across Scotland and Advanced Heart Failure is an invariably fatal condition with only one cure: a transplant.

"Our team support not only those suffering from advanced heart failure, but help their family, friends and loved ones cope with some of the most difficult times in their lives, working day and night to make sure we are offering the highest possible standard of care for everyone who comes through our doors.

"But, with your help, we can do even more.

“We are committed to not only helping more people survive heart failure, but supporting them to have the best quality of life possible. Please, help us celebrate 25 years of heart transplantation by breaking the Guinness World Record and donating to our service, allowing us to find new ways to help more patients across Scotland than ever before.”

The world's longest surviving heart transplant patient died in February, 33 years after his life-saving operation.

John McCafferty, who was originally from Shotts in Lanarkshire, was officially recognised by Guinness World Records in 2013 after his life-saving transplant at Harefield Hospital in west London on October 20, 1982.

He was told the transplant would only add five years to his life at the time.

But he went on to live for more than three decades with the new heart until he died of sepsis and renal failure, aged 73.
