The scariest moment of her life and the doctor who saved her

Kinyetta Campbell shares her journey from the fear and shock of a heart attack to the healing support she received at Northside Hospital Heart Institute.

As Kinyetta faced one of the scariest moments of her life, the calming presence of Dr. Allison Dupont, a cardiologist at Northside Hospital Gwinnett, gave her the strength to trust and believe in her care.

Kinyetta recalls the life-changing moment when Dr. Dupont entered her emergency room, grabbed her hand, and said, "I'm the doctor. You can trust me." This simple yet profound gesture helped Kinyetta feel safe in the hands of one of the best cardiologists in Georgia, as a nurse had previously reassured her, "You are in the best place you can be right now."

Research Excellence

Led by Cindy L. Grines MD, MSCAI, FACC, Chief Scientific Officer, Northside Hospital Heart Institute participates in clinical trials (medical research studies) to improve how we prevent, diagnose, and treat heart disease. These trials help advance medical treatment while giving participating patients an opportunity to receive novel therapies that otherwise would not currently be available.

"Research allows physicians to interact with experts across the globe, and to be among the first to know about new breakthroughs, rather than waiting years for written quidelines to be updated. It is essential for continuing to provide up to date and cutting edge CV care to our patients. Participation in research trials has been proven to improve patient outcomes."
