The demographic, laboratory and clinical characteristics of the study population are found in table 1. The age range was 27 to 81 years (43.26 ± 10.58 years). There were 34 individuals in the age group of 27 to 37 years, 37 individuals in the age group of 38 to 48 years, 19 individuals in the age group of 49 to 59 years, 6 individuals in the age group of 60 to 70 years and 2 individuals in the age group of 71 to 81 years. Table 1 shows the demographic, clinical and laboratory variables of the different groups. Table 2 shows the echocardiographic variables of the different groups. Regarding the echocardiographic variable “LVmass indexed by BSA,” we identified higher values in groups HIV+ PI and HIV- CONTROL compared to groups HIV+NOMEDICATION and HIV+ NNRTI. There were no differences between the groups HIV+ PI and HIV- CONTROL, nor among the groups HIV+ NO MEDICATION and HIV+ NNRTI (Table 2). Regarding the variable “PP” (septal diastolic thickness), we identified higher values in the HIV-CONTROL GROUP. There were no differences between the groups HIV+ PI, HIV+ NO MEDICATION and HIV+ NNRTI (table 2). Regarding the variable “SIV” (posterior wall diastolic thickness), we identified higher values in the HIV-CONTROL GROUP. There were no differences between the groups HIV+ PI, HIV+ NO MEDICATION and HIV+ NNRTI, although the group HIV+ NO MEDICATION presented PP values lower than the others (table 2). 739
