Relationship between deaths from stroke and ischemic heart disease--environmental implications.
We analyzed the ratio of deaths from stroke and ischemic heart disease in Lithuania over a 72-month period (1990-1995) in relation to fluctuations in five physical environmental parameters. Results indicated a highly significant adverse correlation of the stroke/ischemic heart disease death ratio with both solar activity (r = -0.64, p = 0.0001), stronger for women than for men, and the planetary geomagnetic activity index (r = -0.33, p = 0.005). Proton flux > 60 MeV correlated significantly with the death ratio only for the 65-74-year age group (r = -0.36, p = 0.03) (36-month study). The last finding may be a result of different environmental influences on the pathogenesis of ischemic heart disease and cerebral vascular accidents at different ages. We conclude that the monthly ratio of deaths from stroke/ischemic heart disease is related to environmental physical activity.
