READ NOWThe 54-year-old had a heart incident in 2006 when she had to call an ambulance while at work.
She was sent to hospital after her heart rate went up to more than 170 beats a minute.
Ms Lightbody recommends to anyone who is unsure if they are having a heart issue to seek help.
“Don’t just say I’ll be right,” she said.
“If you have a concern, go and get it checked out.”
She has been door-knocking for the appeal for five years now.
“The reason I started doing it was because I thought that would be something good to raise awareness,” she said.
“I have also been giving blood since I was 18. I try to do it every quarter.”
Organisers are hoping for a similar response to this month’s annual appeal that will see more than 100,000 volunteers collecting towards the charity’s $5 million target.
The top area for collections last year in WA was Willetton, which raised $8412. It ranked sixth in the nation.
Port Macquarie in NSW topped the nation’s door-knock donors last year with $15,517, ahead of Buderim in Queensland with $11,098.
