Big breakthroughs. Better health. Because of YOU.
First COVID-19, then a stroke
In the spring of 2021, after more than two weeks in hospital ā and four days in intensive care āKatherine Isaac felt like she was finally recovering from COVID-19.
Suddenly, the room began spinning and her left arm felt strange. When her doctor said sheād su ered a stroke, the 45-year-old active mom thought it was a misdiagnosis.

Then she learned that COVID-19 can trigger blood clots, and one had gone to her brain. She worried about her husband Sheldon and their two young daughters.
While her recovery was tough, she has made great progress. But Katherine manages her expectations:
āI hope for a 100% recovery. But I also need to accept that I might not get 100%.ā
Pushing research forward for those we love
For 70+ years, 95% of the $1.6 billion invested to beat heart disease and stroke has been donor funded. YOU fuel the research that saves lives and helps people like Katherine and her family.

Living an active life could reverse frailty as you age. Why do some people age better than others? Dr. Susan Howlett is working to level the playing ļ¬eld.
As we age, some decline into poor health, while others remain robust.
To ļ¬nd out why, Heart & Stroke researcher Dr. Susan Howlett, a professor of pharmacology and geriatric medicine at Dalhousie University, is targeting frailty ā a condition that happens when health issues leave you depleted and vulnerable.

She has pioneered the idea that overall health can be measured with a āfrailty indexā tool in aging animals. It has shown that āthe mice with the worst functioning hearts and cells were the ones with the highest frailty scores.ā
To address the link between frailty and declining heart function, sheās testing to see if a combination of drugs and exercise will improve frailty.
In keeping with Heart & Strokeās commitment to health equity, Dr. Howlett is excited about the potential of ļ¬nding treatments to reduce frailty across all sex and gender categories. 9 in 10 people in Canada have at least one risk factor for heart disease, stroke or vascular cognitive impairment (VCI). When you give to Heart & Stroke, you are helping to advance breakthrough research like Dr. Howlettās.
YOU make it possible
Former Miss Universe Canada delegate, Samantha Gomez, was 23 when her world turned upside down.
earching for her car keys 7 years ago, Samantha Gomez kept asking her family: āWhere are my limes?ā She didnāt understand why everyone looked worried. Samantha was experiencing the ļ¬rst symptoms of a severe ischemic stroke.
When doctors said recovery would be hard and not guaranteed, ļ¬ance Rob took the next level. Her medical team couldnāt believe her progress. About Canadians who have had a stroke live with some degree of disability that daily activities.
married and parents to Santiago and Camila, Samantha and Rob feel lucky, still ļ¬nding it hard to believe her stroke ever happened: āOur lifestyle is healthy, our family bond is strong. Everyone should know the signs of stroke so they can help themselves and loved ones.ā

Iām interested, not in prolonging lifespan, but prolonging health span ā promoting healthy aging.

Immune system could hold key to preventing heart attacks
Youāre helping Dr. Bryan Heit unlock secrets to target atherosclerosis.
Heart & Stroke support is playing a crucial role. It has allowed us to pursue this project, which is higher-risk.
Dr. Bryan Heit, Heart & Stroke researcher
Weāre ultimately trying to ļ¬nd ways to manipulate the immune system in a way that reverses atherosclerosis,ā says Dr. Bryan Heit, professor of Microbiology and Immunology at Western University.
The most common type of heart disease, atherosclerosis, happens when clumps of fatty plaque build up inside blood vessels in your heart. Those clumps can rupture, blocking blood ļ¬ow and causing a heart attack.
Dr. Heit describes it as an immunological disorder. āWhen cholesterol deposits build up in blood vessels of your heart, your immune system brings cells called macrophages to clean up the mess,ā he says.
In about half of us, that cleanup fails. āThe macrophages, instead of cleaning up that cholesterol, accumulate and die.ā Dr. Heitās team is working to discover what triggers this negative cycle, and then ļ¬nd ways to disrupt it.
With Heart & Stroke funding, they identiļ¬ed GATA2 ā a gene expressed by macrophages as they clean up cholesterol. āWeāre looking at whether targeting GATA2 might be a way of preventing all that from happening.ā To study this, the team uses tissue samples and blood from people undergoing bypass surgery.
Dr. Heitās innovative approach could help people by treating atherosclerosis before it advances. While higher-risk, his findings could prevent heart attacks and save lives.
A love story saved: Thanks to YOU
āItās hard to imagine how sick I was just eight years ago.ā
At 57, Donna logged thousands of kilometers on her bike each year with husband Barry. Imagine their devastation when Donna was diagnosed with heart failure caused by giant cell myocarditis: a rare disease that left her heart damaged beyond repair. Only a heart transplant would save her life.
Then, the unimaginable happened: Barry had a heart attack. He was rushed to emergency where he had surgery to implant stents into his blocked arteries. Less than a week after Barryās surgery the family got the news they wanted: There was a heart for Donna.

you.
Today, Donna and Barry are managing their conditions via check-ups with their cardiologist.
And theyāll continue to do everything they can to maintain their health, especially as new grandparents who love to spoil their granddaughter!
These are the positive outcomes you help make possible. Thank
Making every beat count today ā and tomorrow
Passing on a proud tradition: supporting the cause thatās close to their hearts.
After marrying in 1965, Barrie and Carol Clayton moved the Calgary farm founded by Barrieās grandfather

For years, times were tight, making it hard to donate to organizations they loved. Eventually, they were able to support a few, including Heart & Stroke.
Both have a family history of heart disease.
Now, Heart & Stroke research means even more: āIn āfamily tradition,ā I have heart issues which are fortunately controlled with medications,ā Carol shares. āBarrie has arrhythmia, managed with medication and a pacemakerā.
Barrie and Carol have planned a legacy gift in their Wills: āHeart & Stroke is dedicated to advocating for education around heart disease, like how to better our lifestyle choices and maintain proper health.ā
Setting an example for their children and grandchildren is also important to them. āWe want to leave a legacy of hard work,ā Barrie says. āCareful management of resources and community service to support organizations we feel are valuable.ā

Iām grateful for the medical advances that have been made, because the condition I have isnāt interfering with my lifestyle at all.
Barrie Clayton
