摘　　要：AIM:To evaluate cardiac function and structure in un-treated human immunodeficiency virus(HIV) patients without clinical evidence of cardiovascular disease.METHODS:Fifty-three nave untreated HIV-infected patients and 56 healthy control subjects underwent clinical assessment,electrocardiography(ECG) and echocardiography,including tissue doppler imaging.Moreover,a set of laboratory parameters was obtained from all subjects,including HIV-RNA plasma levels,CD4 cell counts and tumor necrosis factor-α levels.RESULTS:The two groups showed normal ECG traces and no differences regarding systolic morphologic parameters.In contrast,a higher prevalence of left ventricular diastolic dysfunction(abnormal relaxation or pseudonormal filling pattern) was found in the HIV patients(36% vs 9% in patients and controls,respec-tively,P <0.001).CONCLUSION:Subclinical cardiac abnormalities ap-pear in an early stage of the HIV infection,indepen-dent of antiretroviral therapy.The data suggest that HIV per se plays a role in the genesis of diastolic dys-function.AIM:To evaluate cardiac function and structure in un-treated human immunodeficiency virus(HIV) patients without clinical evidence of cardiovascular disease.METHODS:Fifty-three nave untreated HIV-infected patients and 56 healthy control subjects underwent clinical assessment,electrocardiography(ECG) and echocardiography,including tissue doppler imaging.Moreover,a set of laboratory parameters was obtained from all subjects,including HIV-RNA plasma levels,CD4 cell counts and tumor necrosis factor-α levels.RESULTS:The two groups showed normal ECG traces and no differences regarding systolic morphologic parameters.In contrast,a higher prevalence of left ventricular diastolic dysfunction(abnormal relaxation or pseudonormal filling pattern) was found in the HIV patients(36% vs 9% in patients and controls,respec-tively,P <0.001).CONCLUSION:Subclinical cardiac abnormalities ap-pear in an early stage of the HIV infection,indepen-dent of antiretroviral therapy.The data suggest that HIV per se plays a role in the genesis of diastolic dys-function.
