Risk of sudden cardiac death in relation to season-specific cold spells: a case-crossover study in Finland.

ABSTRACT:

Objective

To test a priori hypothesis of an association between season-specific cold spells and sudden cardiac death (SCD).

Methods

We conducted a case-crossover study of 3614 autopsy-verified cases of SCD in the Province of Oulu, Finland (1998-2011). Cold spell was statistically defined by applying an individual frequency distribution of daily temperatures at the home address during the hazard period (7 days preceding death) and 50 reference periods (same calendar days of other years) for each case using the home coordinates. Conditional logistic regression was applied to estimate ORs for the association between the occurrence of cold spells and the risk of SCD after controlling for temporal trends.

Results

The risk of SCD was associated with a preceding cold
