As heart disease continues to remain the leading cause of death in the United States, board-certified cardiologist Dr. Eddie Hackler III is using social media to expand public awareness and improve access to credible health education.
Known online as “Dr. Hack” and @TheBlackDoctor, the Atlanta-based physician is leveraging platforms like TikTok and Instagram to help reshape how Americans understand heart disease, prevention, and cardiovascular health.
At a time when heart disease continues to hold its devastating position as America’s number one killer, Dr. Hackler is determined to close the gap between medicine and the public. In 2023 alone, cardiovascular disease accounted for more than 915,000 deaths in the United States, representing roughly 22% of all deaths nationwide. Coronary heart disease, the leading cause of heart attacks, was responsible for approximately 349,000 deaths that same year. Yet despite those staggering numbers, many people still misunderstand what heart disease actually looks like.
“Millions of Americans think heart attacks look like what they see in movies,” Dr. Hackler explains. “That myth is killing people.”
As one of the few Black cardiologists in the United States, Dr. Hackler represents a rare but critical presence in medicine, standing among the approximately 3% of Black cardiologists nationwide. His journey began at Meharry Medical College, where he earned his Doctor of Medicine degree before continuing his training in internal medicine at the University of Texas Southwestern in Dallas. He later completed his cardiology fellowship at Case Western Reserve University in Cleveland. Today, he practices in Atlanta, Georgia, while simultaneously building a growing digital platform focused on prevention, education, and awareness.
For Dr. Hackler, representation in medicine extends far beyond visibility.
“My journey has made me deeply aware that representation in medicine is not just symbolic,” he says. “It has real consequences for trust, communication, and outcomes.”
That understanding has shaped how he approaches both medicine and content creation. Rather than speaking in intimidating medical jargon, Dr. Hackler simplifies complex health information into practical, digestible messages people can apply to their everyday lives. His goal is not to overwhelm viewers but to empower them.
“This is the first generation in history getting medical education from TikTok and Instagram,” he says. “And it’s saving lives.”
Social media has allowed physicians like Dr. Hackler to meet people where they already spend their time. Instead of waiting for yearly doctor visits, users now encounter life-saving information while scrolling through their feeds during lunch breaks, late nights, or morning commutes. For many, that access has become transformational.
Dr. Hackler says one of the biggest misconceptions he works to correct is the belief that heart attacks always appear dramatic and obvious. In reality, symptoms can be subtle and vary widely. Fatigue, nausea, jaw pain, back pain, shortness of breath, or simply feeling “off” can all be warning signs. Women and younger adults are also frequently overlooked in conversations about cardiovascular health.
“Heart disease does not always feel urgent until it becomes catastrophic,” he explains. “People are often more aware of dramatic events than the quiet, everyday risk factors building in the background.”
He also challenges the assumption that someone who appears physically fit is automatically protected from heart disease. Risk factors such as blood pressure, cholesterol, family history, stress, sleep quality, and metabolic health all play major roles in long-term cardiovascular wellness.
The impact of his online presence has already proven meaningful. Dr. Hackler recalls hearing from viewers who sought emergency care, scheduled cardiology appointments, or finally checked their blood pressure after watching one of his videos.
“Sometimes one message can reach thousands of people at once,” he says, “and among them may be someone who truly needed to hear it that day.”
Beyond encouraging better eating habits and exercise routines, Dr. Hackler urges people to become proactive about knowing their numbers early. Blood pressure, cholesterol levels, blood sugar, waist circumference, and family history all provide important clues about future heart health. He also stresses the importance of sleep, stress management, and regular medical checkups, factors often ignored in mainstream wellness conversations.
As digital platforms continue to evolve, Dr. Hackler believes online education will become an even more important extension of healthcare, particularly in preventive medicine.
“It will not replace doctors or traditional medical care,” he says, “but it can absolutely strengthen prevention, improve awareness, and help people engage with their health earlier.”
At a time when misinformation continues to circulate widely online, Dr. Eddie Hackler III is helping elevate the standard for credible and accessible healthcare communication.
Through his work in medicine, advocacy, and digital education, Dr. Hack is using social media to encourage greater awareness around heart health, proving that informed education and early awareness can play a critical role in saving lives.
