The aim of the present study is to evaluate the prevalence of left ventricular geometric patterns in hypertensive patients in Angola. Methodology: cross-sectional descriptive observational study performed in two diagnostic centers in Luanda. We included all hypertensive patients who underwent transthoracic echocardiographic study in the 2nd quarter of 2012 in both centers. The echocardiographic study was performed according to the ASE recommendations. The relative wall thickness and the presence or absence of echocardiographic left ventricular hypertrophy were used to determine the various geometric patterns Results: 84 patients were included, 33 males and 51 females, the mean age was 52.7 (± 13.4) years. 49% had concentric hypertrophy, 20% had eccentric hypertrophy, and 17% concentric remodeling and 14% had normal geometry. Regarding left ventricular function 87% of had normal systolic function, 64% had diastolic dysfunction. Conclusion: The results show that concentric and eccentric hypertrophy is the most frequent geometric patterns. Diastolic dysfunction is present in majority of the patients. The need for longitudinal studies assessing the prognostic value of geometric patterns in hypertensive patients in Angola, as well as their relationship with left ventricular function is imperative.
