Abbreviations: AMI, acute myocardial infarction; HF/CHF, heart failure or congestive heart failure; IHD, ischemic heart disease; SB, Super Bowl.

^aAnalyses are linear regressions for mortality rate with the following variables included in the model: SB (day of SB and subsequent 14 days vs other days), race (white/Hispanic vs all others), sex (male vs female), age (<65 years vs ≥65 years), and interactions for each of these covariates with the SB variable.
