We analyze the association between the month of birth and age at death in subjects dying from cardiovascular cause in Germany between 1992 and 2007 to test the hypothesis that environmental factors during early pre- or post-natal life may deter- mine cardiovascular mortality later in adulthood. In both sex subgroups, age at death was lowest in subjects born in May and highest in subjects born in November.
