Risk factors associated with methamphetamine use and heart failure among Native Hawaiians and other Pacific Island peoples

OBJECTIVE Heart failure (HF), a long term outcome of chronic methamphetamine use (MU), occurs more frequently in racial and ethnic minority populations at high risk for cardiovascular disparities. This study examined the association of socio-demographic and clinical risk factors with MU among heart failure patients who are Native Hawaiians (NH) or other Pacific Island peoples (PIP). DESIGN/SETTING/PATIENT POPULATION: Cross-sectional study of NHs and PIPs with advanced heart failure enrolled in the Malama Pu'uwai Study, a randomized control trial to test an educational intervention to reduce re-hospitalization and/or death. A total of 82 participants were enrolled between 6/1/06 to 12/31/07 and met the following eligibility criteria: 1) self-identified NH or PIP, 2) Left ventricular systolic ejection fraction 50 years, OR = 0.16, 95% CI, 0.03-0.84; non-married status combined as never married OR = 8.5, CI, 1.5-47; divorced/separated OR = 11, CI 1.8-75). CONCLUSIONS RISK FACTORS ASSOCIATED WITH MU IN NH AND PIPS WITH HEART FAILURE INCLUDE: younger age and being divorced/separated or never married. Health care providers should be aware of MU as a contributing factor in the approach and treatment of HF in NHs and PIPs.
