Incidence and Correlates of Near-Death Experiences in a Cardiac Care Unit

Plain English Summary
In this ambitious 30-month study — the largest of its kind at the time — Greyson tracked nearly 1,600 heart patients to see who reported near-death experiences. The headline: 10% of cardiac arrest survivors described an NDE, versus just 1% of other heart patients. But here's the really fascinating twist: NDEs didn't correlate with how physically close someone was to dying, how sick their heart was, or how their brain was functioning. NDE reporters were younger, more likely to have lost consciousness, and had more prior paranormal-type experiences. This disconnect between NDEs and measurable bodily factors challenges simple "your brain is shutting down" explanations and fuels ongoing debates about the nature of consciousness.
Abstract
Near-death experiences, unusual experiences during a close brush with death, may precipitate pervasive attitudinal and behavior changes. The incidence and psychological correlates of such experiences, and their association with proximity to death, are unclear. We conducted a 30-month survey to identify near-death experiences in a tertiary care center cardiac inpatient service. In a consecutive sample of 1595 patients admitted to the cardiac inpatient service (mean age 63 years, 61% male), of whom 7% were admitted with cardiac arrest, patients who described near-death experiences were matched with comparison patients on diagnosis, gender, and age. Near-death experiences were reported by 10% of patients with cardiac arrest and 1% of other cardiac patients (P.001). Near-death experiencers were younger than other patients (P.001), were more likely to have lost consciousness (P.001) and to report prior purportedly paranormal experiences (P.009), and had greater approach-oriented death acceptance (P.01). Near-death experiencers and comparison patients did not differ in sociodemographic variables, social support, quality of life, acceptance of their illness, cognitive function, capacity for physical activities, degree of cardiac dysfunction, objective proximity to death, or coronary prognosis.
