Key result
Higher acculturation was associated with abnormal cardiac structure and function, including higher LVMI, LAVI, and E/e' but lower e' velocities.
Why the study?
Hispanics/Latinos have a high burden of heart failure risk, but few studies have evaluated the association between acculturation and cardiac structure and function.
Is acculturation associated with changes in cardiac structure and function in Hispanic/Latino adults?

Is acculturation associated with changes in cardiac structure and function in Hispanic/Latino adults?
Higher acculturation among Hispanic/Latino adults in the US is associated with abnormal cardiac structure and function, with effects modified by socioeconomic status.
Acculturation effects on cardiac parameters should not yet alter clinical practice in Hispanics; leaves open need for longitudinal studies to confirm associations.
OBJECTIVE: Hispanics/Latinos, the largest immigrant population in the USA, undergo the process of acculturation and have a large burden of heart failure risk. Few studies have examined the association of acculturation on cardiac structure and function. DESIGN: Cross-sectional. SETTING: The Echocardiographic Study of Latinos. PARTICIPANTS: 1818 Hispanic adult participants with baseline echocardiographic assessment and acculturation measured by the Short Acculturation Scale, nativity, age at immigration, length of US residence, generational status and language. PRIMARY AND SECONDARY OUTCOME MEASURES: Echocardiographic assessment of left atrial volume index (LAVI), left ventricular mass index (LVMI), early diastolic transmitral inflow and mitral annular velocities. Multivariable analyses demonstrated higher LAVI with increasing years of US residence. Foreign-born and first-generation participants had higher E/e' but lower LAVI and e' velocities compared with the second generation. Higher acculturation and income >$20K were associated with higher LVMI, LAVI and E/e' but lower e' velocities. Preferential Spanish-speakers with an income <$20K had a higher E/e'. CONCLUSIONS: Acculturation was associated with abnormal cardiac structure and function, with some effect modification by socioeconomic status.

López et al. (2019) conducted a cross-sectional in Heart failure risk (n=1,818). Acculturation vs. Lower acculturation was evaluated on Left atrial volume index (LAVI), left ventricular mass index (LVMI), early diastolic transmitral inflow and mitral annular velocities. Higher acculturation was associated with abnormal cardiac structure and function, including higher LVMI, LAVI, and E/e' but lower e' velocities.
