"I am very thankful to have had access to Longevity Health for a coronary CTA and calcium analysis. With no history of heart issues, I was recently diagnosed with Afib. The team's coronary scans and AI imaging created detailed 3D images which assessed blood flow and plaque buildup. Dr. Young and his staff provided outstanding analysis that far exceeded conventional blood tests. I highly recommend scheduling a consultation if you're serious about taking a proactive approach to cardiac health."
