THE GEOGRAPHY OF CARDIOVASCULAR DISEASE IN TEXAS

Cardiovascular disease is the leading cause of death in Texas accounting for 30% of all deaths in 2004. In fact, heart disease and stroke remain the first and third leading cause of death. Much higher rates occur in the eastern part of the state, an area known to have soft water. East Texas is also home to high concentrations of Blacks, a people known to suffer disproportionately from heart disease and stroke. In contrast, the western part of the state, with hard water, has much lower rates, and much higher concentrations of Hispancis, a people known to have relatively lower heart disease mortality despite limited insurance access.

Using GIS and statistical analysis, this study examines and attempts to explain the spatial distribution of cardiovascular disease mortality in Texas counties. The results suggest that in addition to behavior risk factors for cardiovascular disease, the soft water environment occupied by Blacks may be an important but frequently neglected cardiovascular disease risk factor.
