  1. Electrocardiographic left ventricular hypertrophy by five criteria among civil servants in Benin City, nigeria : prevalence and correlates.

    Article - En anglais

    Although increasing hypertension rates have been reported in several African populations, little is known about the frequency of resulting hypertensive complications in these populations.

    We recorded the electrocardiograms of 482 male and 284 female civil servants in Benin City, Nigeria.

    Five different criteria were used to detect the presence of electrocardiographic left ventricular hypertrophy.

    Associations between electrocardiographic left ventricular hypertrophy and demographic, anthropometric and blood pressure characteristics were assessed.

    The prevalence of electrocardiographic left ventricular hypertrophy ranged from 3 to 29% in the total population, depending on the criteria used, with four of the five criteria resulting in prevalence estimates of less than 10%. The prevalence of electrocardiographic left ventricular hypertrophy was significantly greater among those with hypertension (19% of the total population), ranging from 11 to 49%. The prevalence of electrocardiographic left ventricular hypertrophy increased with blood pressure level in both normotensives and hypertensives.

    Among hypertensives with systolic blood pressure >=180 mmHg or diastolic blood pressure >=110 mmHg, the prevalence exceeded 50% by four of the five criteria.

    We conclude that left ventricular hypertrophy may be affecting many hypertensives in this Nigerian population, potentially resulting in a substantial future burden of cardiovascular disease and death.
