Mis[s]diagnosed set out to expose the medical gender data gap that leaves women 78% more likely to be misdiagnosed during heart attacks, with symptoms like jaw pain, indigestion, or back pain often dismissed due to male-centric research. The campaign began with a survey of 4,000 Arab women that revealed 97.4% did not know the signs of a woman’s heart attack, followed by sending one Arab woman undercover to meet healthcare professionals where 83% failed to recognize her symptoms. Her story and the data were then packaged into handcrafted Awareness Aid Kits, a modern twist on First Aid boxes featuring brochures, audio storytelling, and a stethoscope-activated sound device and distributed to influencers, doctors, cardiologists, and teaching hospitals across the region. These kits became catalysts for unboxings and shares online, amplified by influencers through the hashtag #KnowTheSigns and supported by owned social placements, while teaching hospitals and medical seminars extended the conversation on the ground. On World Heart Day the campaign peaked with a fully integrated rollout across Egypt, Kuwait, UAE, Saudi Arabia, Lebanon, and Bahrain, reaching millions of women and medical professionals, before being sustained through partnerships with thousands of companies to encourage women to participate in clinical trials via the #ClinicalEqualityInitiative. The effort reached 28.7M people, generated $2.2M in earned media, educated 28M women on early warning signs, drove a 23% uplift in clinical trial interest, enlisted 12 heart foundations and 3 teaching hospitals, and even saved a woman’s life, proving that reframing one word could reframe the global conversation on women’s health.
