Background: Sudden cardiac deaths (SCD) are important clinical end points to assess the outcomes of many cardiovascular conditions. Examination of seasonal variation of certain diseases has led to new insights into pathophysiologic triggers. We assessed the seasonal variations in SCD.
Methods: The NIS database was used to estimate the annual number of admissions with primary diagnosis of SCD (427.5) from 2006-2012 using the International Classification of Diseases-9-CM diagnosis codes as the principal discharge diagnosis. The frequency of SCD for each month cumulative over 7 years was calculated. It was divided by number of days in that month to obtain the mean SCDs per day for each month. All calculations were carried out using the weighted estimates approximating nationwide population estimates.
Results: A total of 953,871 patients had SCD 2006 to 2012. SCD were maximum in the winter months and lesser in the summer months. The mean number of SCD each day (averaged over 7 years) was least in July. The average number of SCD was highest in February; thereafter, dropped to a nadir in July and again rose thereafter to reach a peak in February.
Conclusions: We identified an impressive pattern of seasonal variation in SCD. This pattern was seen in all subgroups analyzed as well as in different geographic areas. Documentation of such a pattern may foster investigation of new pathophysiologic determinants
