Megan Kaverman began experiencing symptoms at 18, including weight gain and shortness of breath, but doctors were unable to identify the cause, with one even suggesting she eat less pizza and others dismissing her high blood pressure as nerves.
At 25 she developed severe fatigue and breathing difficulties, and repeated emergency room visits produced no answers, with physicians insisting she was too young to have a heart problem.
In 2016, at age 27, Kaverman returned to the ER refusing to leave without a diagnosis; tests revealed early-stage heart failure, and an intensive ICU evaluation identified heritable pulmonary arterial hypertension, a rare genetic heart disease.
Kaverman called the day of her diagnosis her "rebirth" and sought treatment at the Cleveland Clinic, which she credits with allowing her to return to daily life.
Two years later, Kaverman recognized the same symptoms in her sister, Katie Gusching, then 32 and a new mother, who struggled to breathe during chores, experienced leg swelling, and briefly lost her vision.
After Kaverman urged her to ask about pulmonary hypertension, Gusching underwent the same tests and received the same diagnosis, and she credits her sister's persistence with saving her life.
