Twin sisters Mairead Lyons and Therese Walsh experienced rare SCAD heart attacks just a year apart, an ordeal that brought them closer and highlighted the importance of support networks like the Irish Heart Foundation.
Mairead, from Trim, Co. Meath, was a healthy, active 38-year-old when she suffered a spontaneous coronary artery dissection (SCAD) in September 2023. The event was life-changing—she faced physical challenges, emotional trauma, and was told she couldn’t have more children. The psychological impact was profound, but finding the Irish Heart Foundation’s resources made a meaningful difference.
“I received the SCAD information booklet from a nurse in the hospital and that led me to the Irish Heart Foundation where I’ve spoken to your nurses on the Nurse Support Line and they’ve been amazing. Seeing all the different information, on the website makes you feel like you’re not alone. I’m part of the Heart Support Network, and a WhatsApp group for SCAD Ireland and I’ve met a few people from the group in person which is genuinely helpful.” Counselling for PTSD has also been a huge help for Mairead.
Her twin, Therese, from Rathangan, Co. Kildare, experienced her own SCAD during fertility treatment in 2024. Because she knew about Mairead’s experience, she sought help promptly, which proved lifesaving. “Honestly, I wouldn’t have gone in if I didn’t know about Mairead.,” she says. Life after SCAD comes with some worries for Therese but thankfully with support from others including the Irish Heart Foundation, SCAD Ireland and her sister Mairead, recovery went well - “we now have a little boy, Jack and we’re all doing great”.
Mairead and Therese are now advocates for women’s heart health, through the Irish Heart Foundation’s “Her Heart Matters” campaign, encouraging others to seek support and not underestimate the impact of stress on heart health. “Listen to your body, particularly in stressful situations, and take some time to yourself, which is easier said than done. Take yourself more seriously if you’re not feeling well.” says Therese
Both sisters emphasise how crucial the Irish Heart Foundation’s support has been in their recovery. The Foundation’s resources, nurse helplines, online communities, and patient panels provided practical advice, emotional reassurance, and a sense of belonging.
