We compared the effects of hot and cold spells on cardiovascular mortality in the Czech Republic over 1986–2006 and examined differences between population groups. We used analogous definitions for hot and cold spells that are based on quantiles of daily average temperature anomalies and do not incorporate any location-specific threshold. Epidemics of influenza/acute respiratory infections were identified, and corresponding periods were excluded from the analysis. Both hot and cold spells are associated with significant excess cardiovascular mortality. The effects of hot spells are more direct (unlagged) and typically concentrated in a few days of a hot spell, while cold spells are associated with indirect (lagged) mortality impacts persisting after a cold spell ends. Although the mortality peak is less pronounced for cold spells, the cumulative magnitude of excess mortality is larger for cold than hot spells.
