UNLABELLED: The goal of this study was to check: 1) links between month of the year (1-12), monthly solar activity (SA) and monthly geomagnetic activity (GMA) with the temporal distribution of deaths from ischemic heart disease (IHD) and stroke in Israel and Lithuania (48 months); 2) related age and gender differences; 3) temporal connection between deaths from IHD and suicide and their relationship to SA and GMA, as was suggested in our previous study in Israel. RESULTS: Total deaths from IHD in Lithuania showed a trend towards a link with SA (r = 0.25, p = 0.09) and a highly significant correlation for females (r = 0.37, p = 0.00096) but not for males. Age < 74 showed no correlation with SA or GMA in females, but a negative correlation with SA in males (r = -0.513, p = 0.0002). At age > 74 both females (r = 0.467, p = 0.0006, n = 20763) and males (r = 0.476, p = 0.0006, n = 14682) showed a highly significant correlation with SA and a negative correlation with 1-12 months of the year, with deaths concentrating at the beginning of the year (r = -0.32, p = 0.002). Number of monthly suicide and IHD deaths were negatively related to each other (r = -0.45, p = 0.0014). CONCLUSIONS: 1) Around age 70 an increasingly positive relationship between the temporal distribution of deaths from IDH and SA is seen. 2) Gender differences in links to SA are partially a consequence of the higher number of deaths in females from IHD at age > 74.3) Monthly number of suicides is inversely related to number of deaths from IHD.
