PURPOSE: Pulmonary hypertension, which is listed on hospital records and death certificates as either primary (i.e., idiopathic) pulmonary hypertension or pulmonary hypertension secondary to another underlying condition or disease, is considered rare amongst the U.S. population. Few reports have been published regarding surveillance data for this debilitating and often fatal condition. Aim:To assess trends in death and hospitalization with pulmonary hypertension in the US.

METHODS: For the years 1999-2008, we examined multiple cause of death mortality data from the National Vital Statistics System (NVSS) and hospital discharge data from the National Hospital Discharge Survey (NHDS) for 1999--2009. NVSS, maintained by CDC's National Center for Health Statistics (NCHS), compiles multiple cause of death information from official death certificates filed in the United States. NHDS, also conducted annually by NCHS, includes information on discharges from a sample of nonfederal, short-stay hospitals. Because pulmonary hypertension might be reported secondary to other diseases, this report presents data for pulmonary hypertension as any contributing cause of death or any-listed hospital diagnosis.

RESULTS: Since 1999, the number of deaths and hospitalizations, as well as death rates and hospitalization rates have increased for pulmonary hypertension, particularly among women and older adults. During 1999 death rates were higher for men than women; however, by 2002, no difference in rate was observed because of increasing death rates among women and declining death rates among men; after 2003 higher death rates were observed for women. Death rates throughout the reporting period 1990-2008 have been higher for blacks than for whites. In addition, a higher rate of hospitalization was observed in the Northeast than in other regions of the United States.

CONCLUSIONS: Increases in rates of mortality from and hospitalization for pulmonary hypertension were observed in the US in 1999-2009.

CLINICAL IMPLICATIONS: More research is needed concerning cause, prevention, and treatment of pulmonary hypertension. Additional epidemiologic initiatives also are needed to ascertain prevalence and incidence of various pulmonary hypertension disease entities such as pulmonary arterial hypertension.
