We calculated cardiovascular disease mortality rates associated with 2009 pandemic influenza A H1N1 infection with the ratio of excess deaths from cardiovascular and respiratory diseases during the pandemic in five countries and multiplied these values by the crude respiratory disease mortality rate associated with the virus.

Influenza-associated mortality is often estimated indirectly, by use of statistical models, as the number of excess deaths during periods of circulation of the virus.

Additionally, methods to estimate excess mortality require the availability of vital statistics data that are sparse in some regions of the world and not always available in aggregate until 2–3 years after deaths are reported in countries that do have data.

First, we calculated ratios of estimated cardiovascular to respiratory deaths associated with 2009 pandemic influenza A H1N1 using estimates of excess circulatory and respiratory deaths attributed to the virus in five high-income and middle-income countries stratified by age 64 years and younger and older than 64 years.
