MiscellaneousMajor and Minor Electrocardiographic Abnormalities and Their Association With Underlying Cardiovascular Disease and Risk Factors in Hispanics/Latinos (from the Hispanic Community Health Study/Study of Latinos)
Section snippets
Methods
The HCHS/SOL is a population-based cohort study designed to examine risk and protective factors for chronic diseases and quantify morbidity and mortality prospectively. Details of the sampling methods and design have been published.24, 25, 26 Briefly, from March 2008 to June 2011, 16,415 self-identified Hispanic/Latino subjects from diverse background (Cubans, Dominicans, Mexicans, Puerto Ricans, Central Americans, and South Americans) aged 18 to 74 years were examined. Participants were
Results
Baseline characteristics of the study group are listed in Table 1. At baseline examination, men had greater prevalence of a history of hypercholesterolemia, being current smokers, having a history of heart attack and coronary revascularization; they had higher systolic and diastolic blood pressures. Women were older, more obese, and had faster heart rates.
The prevalent age-adjusted major and minor ECG abnormalities comparing men and women are listed in Table 2. Major ECG abnormalities were more
Discussion
The existing data on ECG findings are derived from largely white population.1, 3, 4, 5, 7, 8, 10, 11, 14 However, a number of studies have focused on groups with different racial backgrounds. The Strong Heart study examined ECG abnormalities among American Indians.17 The Honolulu Heart Program examined the predictive value of electrocardiogram in men of Japanese descent.18 The Evans County and Charleston Heart studies showed that African-Americans have a greater prevalence of ECG abnormalities
