What is the long-term association of hurricane-related flooding with cardiovascular disease (CVD) risk?In this cohort study of 121 395 continuously enrolled Medicare fee-for-service beneficiaries residing in New Jersey, New York City, and Connecticut, 5-year CVD event rates were higher for zip codes exposed to flooding from Hurricane Sandy than nonflooded zip codes, with the greatest risk noted approximately 3 years after landfall for heart failure events in New Jersey.These findings suggest that hurricane flooding is associated with long-term CVD risk up to 5 years after landfall.
