To examine the spatial variation of stroke mortality risk during heat wave, we collected 418 cases with permanent addresses for a severe wave (July 28-August 15, 2010) and 624 reference period 29-August 16, 2009 July 27-August 14, 2011) in Nanjing, China. Generalized additive models were used to explore association between location while controlling individual-level factors. Heat vulnerability was then applied explain possible variations heat-wave-related risk. The overall ratio (95% confidence intervals) due Nanjing 1.34 (1.21 1.47). Geolocation found be significantly associated Using alternative periods generated similar results. A district-level assessment revealed patterns. highest observed Luhe district combination high exposure vulnerability. Our findings provide evidence that is higher rural areas waves these require future interventions reduce
