About
Dr. David Saintsing co-founded Ikigai Health Institute after more than 25 years in emergency medicine. He began his clinical career in 1999 and practiced across a wide range of health systems nationwide, from community hospitals to larger academic centers. Over those decades, he repeatedly encountered patients arriving at a point of no return from conditions that had been detectable years earlier. That pattern convinced him that catching risk early and intervening with precision is the more meaningful form of medicine.
At Ikigai, Dr. Saintsing focuses on cardiovascular and metabolic diagnostics, longitudinal biomarker tracking, and individualized intervention strategies. He holds deep clinical interest in ApoB, Lp(a), insulin resistance, biological age, atherosclerosis, and cognitive decline. His patients include executives, entrepreneurs, and high-performing individuals who want a data-driven approach to healthspan. A former competitive triathlete and active investor in healthcare innovation, Dr. Saintsing believes that how well you age matters as much as how long.

Frequently Asked Questions
Dr. Saintsing focuses on cardiovascular risk, metabolic dysfunction, insulin resistance, atherosclerosis, hypertension, prediabetes, cognitive decline, hormonal imbalance, and cancer prevention. His clinical approach centers on identifying these conditions early, before they reach a crisis stage. He uses advanced diagnostics to build individualized intervention plans for each patient.
Dr. Saintsing uses a broad toolkit of advanced diagnostics including ApoB and Lp(a) lipid panels, coronary calcium scoring, coronary CT angiography, continuous glucose monitoring, epigenetic testing, and DEXA body composition scanning. He also integrates wearable data from devices like Oura and Whoop into a clinical dashboard to track longitudinal trends over time.
Dr. Saintsing works primarily with executives, entrepreneurs, and driven individuals who want a proactive, data-driven approach to their health. Many of his patients carry cardiovascular or metabolic risk factors they want to address years before those risks become problems. He also sees patients focused on cognitive protection and long-term healthspan optimization.
Dr. Saintsing trained in emergency medicine and built a 25-year career across community and larger health systems nationwide. His clinical focus at Ikigai centers on preventive medicine and executive health, applying the diagnostic rigor of emergency medicine to early risk detection and long-term longevity planning.
Dr. Saintsing evaluates cardiovascular risk using advanced markers that standard panels often miss. He assesses ApoB, Lp(a), coronary calcium scores, and coronary CT angiography findings to build a detailed picture of a patient's actual risk. His goal is to identify and modify risk trajectories years before a cardiac event becomes possible.
Yes. Dr. Saintsing treats cognitive decline and dementia prevention as a core part of longevity medicine. He focuses on the metabolic and vascular drivers of brain aging, including insulin resistance and atherosclerosis. His approach combines advanced biomarker testing with individualized strategies to protect cognitive function over time.
Dr. Saintsing integrates data from wearables like Oura, Whoop, and Apple Watch into a centralized clinical dashboard. This allows him to track trends in heart rate variability, sleep quality, and other physiological signals over time. He treats wearable data as one input within a broader, clinically grounded picture of each patient's health.
