Key result
Daily neutron activity shows no link to overall sudden cardiac death, despite an association with myocardial rupture.
Why the study?
The relationship between neutron activity and timing and type of sudden cardiac death (SCD) classified by ICD10 codes 121-125 was unclear.
Does daily neutron activity correlate with the occurrence and type of sudden cardiac death?
Population
848 SCD patients from Kaunas registry (2002-2004), 68.28% male
Comparison
Days with higher neutron activity vs days with lower or no neutron activity
Design
Observational study with forensic post mortem examination and ICD10 classification
Follow-up
2002-2004

No overall SCD-neutron activity link; observational data leave open hypothesis-generating subgroup signals in younger men and rupture cases.
Observational (n=848)
Yes
Does daily neutron activity correlate with the occurrence and type of sudden cardiac death?
While overall sudden cardiac death did not correlate with daily neutron activity, specific subgroups such as men under 65 and cases of myocardial rupture showed an association with higher neutron activity.
Stoupel et al. (2006) conducted an observational in Sudden cardiac death (SCD) (n=848). Daily neutron activity vs. Days without sudden cardiac death was evaluated on Sudden cardiac death occurrence. Daily neutron activity did not differ on days with or without sudden cardiac death, though higher activity was noted on days of SCD with myocardial ruptures (p=0.037).
