A Renfrewshire mum has told how she feared she would die after suffering a heart attack at the age of 37 during the UK's first coronavirus lockdown.

Lee Anne Porteous believed she was fit and healthy before she started feeling unwell while on a dog walk in May last year.

The Barclays bank worker said she developed pain in her jaw but thought she was suffering from toothache.

"I didn't think much of it," added Lee Anne, who is married to Alan and mum to six-year-old Emma. "I thought I might need to go to the dentist but we'd just gone into lockdown.

"I was feeling pretty lousy, so I thought I'd have an early night. Then I woke up about 1am and the pain from my mouth had actually spread into my chest.

"I felt sick and my stomach was hurting. I felt clammy and then I got pins and needles down my arm.

"Eventually I got my husband to call NHS 24 for some advice and, as soon as I told the lady my symptoms, she said she was going to get an ambulance."

When paramedics arrived, they told Lee Anne she was having a heart attack.

She was rushed to the Golden Jubilee Hospital, in Clydebank, where she underwent emergency surgery to fit a stent in her blocked artery.

"It was quite a shock but, at that time, I just felt numb," said Lee Anne. "It was probably after a couple of weeks that it hit me.

"I got it into my head I was going to die and I started worrying about my wee girl, about whether she was going to be affected when she's older.

"I'm a lot more positive about it now. I just want to do what I can to look after myself and enjoy my life to the best I can."

Doctors do not know exactly what caused the cardiac episode, particularly given Lee Anne had none of the "risk factors" associated with heart attacks, such as smoking and obesity.

"I'll never know exactly why it happened," she said. "That's why I want people to be aware of the symptoms of a heart attack.

"You can be young like me and have none of the risk factors, think you're fit and healthy and you can still have one."
