Abstract
OBJECTIVES Prevalence of cardiovascular disease increases with age. Little is known about the prevalence and risk factors for echocardiographic abnormalities among older people living with HIV (PLHIV) from Asia. DESIGN A cross-sectional study was conducted among PLHIV aged >50 years (N = 298) on antiretroviral treatment (ART) and HIV-negative controls (N = 100) frequency matched by sex and age in Thailand. METHODS All participants underwent standard 2-dimensional transthoracic echocardiography performed by trained cardiologists who were blinded to the participant's care and HIV status. Logistic regression was used to examine the association between cardiac abnormalities and risk factors. RESULTS The median age was 54.7 years (60.8% men) with 37.2% having hypertension and 16.6% having diabetes mellitus. PLHIV was on ART for a median of 16.2 years with current CD4 cell counts of 616 cells per cubic millimeter. Echocardiogram abnormalities did not differ among PLHIV (55%) and the controls (60%). The major abnormalities in PLHIV were following: left ventricular (LV) hypertrophy: 37% men and 42.2% women, LV systolic dysfunction (0.7%), diastolic dysfunction (24.2%), and pulmonary hypertension (3.9%). From the multivariate analyses in PLHIV, being aged >60 years was independently associated with diastolic dysfunction, whereas female sex and left atrial volume index of >34 mL/m were associated with pulmonary hypertension (P < 0.05). None of the ART was significantly associated with any major echocardiographic abnormalities. CONCLUSIONS In this long-term, well-suppressed, older, Asian PLHIV cohort, the prevalence of asymptomatic LV systolic dysfunction and pulmonary hypertension were relatively low, whereas the diastolic dysfunction and LV hypertrophy were common. Echocardiographic findings did not differ between PLHIV and HIV-uninfected controls.

Abstract
BACKGROUND The effects of HIV and antiretroviral therapy on cardiovascular system of perinatally infected children throughout their development are not fully understood. OBJECTIVES To determine the prevalence of cardiac abnormalities in a retrospective cohort of perinatally HIV-infected patients and to investigate associations between echocardiographic and clinical data during their follow-up. METHODS Review of medical records and echocardiogram reports of 148 perinatally HIV-infected patients between January 1991 and December 2015. RESULTS Four hundred and eighty echocardiograms were analyzed and 46 (31%) patients showed cardiac abnormalities, frequently subclinical and transient. Nadir CD4 count was higher in patients with consistently normal echocardiogram: 263 (4-1480) versus 202 (5-1746) cells/μL, P = 0.021. Right ventricular (RV) dilation was detected in 18.9%, left ventricular (LV) dilation in 21.6%, septal hypertrophy in 12.2%, LV posterior wall hypertrophy in 6%, LV systolic dysfunction in 8% and pulmonary hypertension in 8.7% of patients. Opportunistic infections were associated with RV dilation [odds ratio (OR = 4.34; 1.78-10.53; P < 0.01)], pulmonary hypertension (OR = 8.78; 2.80-27.51; P < 0.01) and LV systolic dysfunction (OR = 5.38; 1.55-18.71; P < 0.01). Longer duration of highly active antiretroviral therapy was associated with reduced risk of LV dilation (OR = 0.91; 0.85-0.97; P < 0.01) and systolic dysfunction (OR = 0.71; 0.59-0.85; P < 0.01). Protease inhibitors use was associated with reduced risk of RV dilation (OR = 0.54; 0.30-0.97; P < 0.05), LV dilation (OR = 0.35; 0.21-0.60; P < 0.01) and LV systolic dysfunction (OR = 0.07; 0.02-0.31; P < 0.01). Higher CD4 count was associated with lower risk of LV systolic dysfunction (OR = 0.82; 0.69-0.98; P < 0.05). CONCLUSIONS Echocardiograms identified cardiac abnormalities among children with perinatally acquired HIV infection, and data suggest that immunologic status and therapeutic strategies throughout development can influence cardiac disease burden in this population.

Abstract
HIV infection and/or antiretroviral therapy may increase the risk of subclinical coronary atherosclerosis. However, patients with chronic kidney disease (CKD) and those without IV access cannot undergo contrast-enhanced coronary CT angiography (CCTA). This study was to explore the relationship between cardiac troponin T (cTnT) levels and the extent of coronary plaque burden, as assessed by CCTA in those with HIV infection. Between June and September 2017, 58 HIV-infected participants were recruited and underwent contrast-enhanced CCTA. cTnT was measured with the Elecsys Troponin T Gen 5 STAT assay, and noncalcified plaque burden was quantified using coronary plaque analysis. Robust regression model was employed to perform primary statistical analysis. Univariate robust regression analysis indicated that male gender, cardiovascular risk score defined by the 2013 ACC/AHA cardiovascular risk score algorithm, and cTnT levels were significantly associated with noncalcified plaque volume index (NCPI). Final robust regression analyses showed that only cTnT (log scale) was independently associated with the NCPI (regression coefficient: 0.0453 with 95% CI: 0.0151, 0.0755, p = 0.003). These results of this study suggest that cTnT may be a promising marker for coronary plaque burden, especially in patients with HIV-associated CKD or without IV access.

Abstract
BACKGROUND Involvement of right-sided heart chambers (RSHCs) in patients infected with human immunodeficiency virus (HIV) is common and is usually attributed to pulmonary arterial or venous hypertension (PH). However, myocardial involvement in patients with HIV is also common and might affect RSHCs even in the absence of overt PH. Our aim was to define morphologic and functional alterations in RSHC in patients with HIV and without PH. METHODS AND RESULTS A total of 50 asymptomatic patients with HIV and 25 control subjects without clinical or echocardiographic signs for PH were included in the study. Transthoracic echocardiography was used to obtain measurements. Patients with HIV had significantly increased right ventricular end-diastolic diameter (RVEDD) and right ventricular free wall thickness (RVFWT), as well as increased right atrial area and pulmonary arterial diameter, compared with control subjects. After adjustment for age, sex, and body surface area, RVFWT (average 1.81 mm, 95% confidence interval [CI] 0.35-3.26 mm) and RVEDD (average 6.82 mm, 95% CI 2.40-11.24 mm) were significantly higher in subjects infected with HIV. More patients with right ventricular hypertrophy were on antiretroviral treatment, and RVFWT was on average 1.3 mm higher (95% CI 0.24-2.37 mm) in patients on antiretroviral treatment after adjustment for confounders. CONCLUSIONS These findings suggest that alterations in RSHCs were present in patients with HIV without PH.

Abstract
BACKGROUND Electrocardiographic (ECG) abnormalities are prevalent in subjects with human immunodeficiency virus (HIV) infection. In this study, three groups of subjects were investigated and the prevalence of ECG abnormalities was analysed. METHODS A cross-sectional study was carried out on adults between November 2010 and November 2011 at the University of Nigeria Teaching Hospital, Enugu, Nigeria. One hundred HIV-infected patients on highly active anti-retroviral therapy (HAART), 100 HIV-infected HAART-naïve patients and 100 HIV-negative controls were recruited. Twelve-lead electrocardiograms were done on all subjects. Data were analysed using the chi-squared, Student's t-, one-way ANOVA and Duncan post hoc tests. RESULTS Left-axis deviation was seen in 15 (16%) of the HIV-positive subjects on HAART, 10 (13.7%) of the HAART-naïve subjects and eight (21%) of the controls (p = 0.265). Eight (11%) subjects with left ventricular hypertrophy (p < 0.001) and two (2.7%) with ST-segment elevation were found among the HIV-positive HAART-naïve subjects (p = 0.134). Prolonged QTc interval was seen in 17 (18.2%) of the HIV-positive patients on HAART, 12 (16.4%) of the HIV-positive HAART-naïve patients and four (10.5%) of the controls (p = 0.012). CONCLUSION The prevalence of ECG abnormalities was higher in the HIV-positive patients on HAART (93%) and the HIV-positive HAART-naïve patients (73%) compared to the controls.

Resveratrol Co-Treatment Attenuates the Effects of HIV Protease Inhibitors on Rat Body Weight and Enhances Cardiac Mitochondrial Respiration. PLoS One 2017; 12:e0170344.

Abstract
Since the early 1990s human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) emerged as a global health pandemic, with sub-Saharan Africa the hardest hit. While the successful roll-out of antiretroviral (ARV) therapy provided significant relief to HIV-positive individuals, such treatment can also elicit damaging side-effects. Here especially HIV protease inhibitors (PIs) are implicated in the onset of cardio-metabolic complications such as type-2 diabetes and coronary heart disease. As there is a paucity of data regarding suitable co-treatments within this context, this preclinical study investigated whether resveratrol (RSV), aspirin (ASP) or vitamin C (VitC) co-treatment is able to blunt side-effects in a rat model of chronic PI exposure (Lopinavir/Ritonavir treatment for 4 months). Body weights and weight gain, blood metabolite levels (total cholesterol, HDL, LDL, triglycerides), echocardiography and cardiac mitochondrial respiration were assessed in PI-treated rats ± various co-treatments. Our data reveal that PI treatment significantly lowered body weight and cardiac respiratory function while no significant changes were found for heart function and blood metabolite levels. Moreover, all co-treatments ameliorated the PI-induced decrease in body weight after 4 months of PI treatment, while RSV co-treatment enhanced cardiac mitochondrial respiratory capacity in PI-treated rats. This pilot study therefore provides novel hypotheses regarding RSV co-treatment that should be further assessed in greater detail.

Abstract
Background The key objectives of this study were to examine whether HIV infection itself is associated with subclinical coronary atherosclerosis and the potential contributions of cocaine use and antiretroviral therapies (ARTs) to subclinical coronary artery disease (CAD) in HIV‐infected persons. Methods and Results Between June 2004 and February 2015, 1429 African American (AA) adults with/without HIV infection in Baltimore, Maryland, were enrolled in an observational study of the effects of HIV infection, exposure to ART, and cocaine use on subclinical CAD. The prevalence of subclinical coronary atherosclerosis was 30.0% in HIV‐uninfected and 33.7% in HIV‐infected (P=0.17). Stratified analyses revealed that compared to HIV‐uninfected, HIV‐infected ART naïve were at significantly lower risk for subclinical coronary atherosclerosis, whereas HIV‐infected long‐term ART users (≥36 months) were at significantly higher risk. Thus, an overall nonsignificant association between subclinical coronary atherosclerosis and HIV was found. Furthermore, compared to those who were ART naïve, long‐term ART users (≥36 months) were at significantly higher risk for subclinical coronary atherosclerosis in chronic cocaine users, but not in those who never used cocaine. Cocaine use was independently associated with subclinical coronary atherosclerosis. Conclusions Overall, HIV infection, per se, was not associated with subclinical coronary atherosclerosis in this population. Cocaine use was prevalent in both HIV‐infected and ‐uninfected individuals and itself was associated with subclinical disease. In addition, cocaine significantly elevated the risk for ART‐associated subclinical coronary atherosclerosis. Treating cocaine addiction must be a high priority for managing HIV disease and preventing HIV/ART‐associated subclinical and clinical CAD in individuals with HIV infection.

Abstract
PURPOSE Recent studies have shown that HIV infection is independently associated with heart failure. Diastolic dysfunction (DD) is frequent in HIV patients, but it is unclear whether this is an effect of the HIV infection itself or of the anti-retroviral therapy (ART). Our aim was to compare diastolic function in HIV treatment-naïve, HIV-ART patients and controls. METHODS We prospectively enrolled 206 consecutive patients with HIV-1 infection and 30 controls, selected by frequency matching for age and sex. HIV patients were divided in two subgroups: ART-naïve (n = 88) and ART (n = 118). Diastolic function was assessed and graded by echocardiography, according to modern consensus criteria and using tissue Doppler analysis. RESULTS Compared to controls, ART-naïve patients had lower E' velocities (E' septal: 10.2 ± 2.4 vs 11.9 ± 2.6 cm/s, p = 0.02), higher E/E' ratio (7.8 ± 1.9 vs 6.9 ± 1.6,p = 0.02) and higher prevalence of DD (19 % vs 3.3 %,p = 0.05). HIV patients under ART also had worse diastolic function compared to controls (E' septal: 10.3 ± 2.5 cm/s;p < 0.01; E/E'ratio: 8.0 ± 2.0,p < 0.01; DD prevalence: 23 %;p = 0.01), but no significant differences were found between ART-naïve and ART HIV subgroups. In multivariable logistic regression analysis, age and body mass index were the only independent predictors of reduced diastolic reserve in HIV patients. Regarding systolic function, there were no significant differences in ejection fraction or S' velocities between controls and HIV subgroups. CONCLUSIONS HIV treatment-naïve patients have reduced diastolic reserve that is not worsened by ART. These data reinforce the association of diastolic dysfunction with the HIV infection itself and not with the anti-retroviral therapy.

Abstract
BACKGROUND Previous studies have demonstrated increased risk of adverse cardiac outcomes in adults with HIV infection. However, few studies have addressed this problem in vertically HIV-infected children and adolescents, and the long-term cardiac health of this unique population in the antiretroviral therapy era is still unknown. METHODS Ventricular function was evaluated cross-sectionally in a group of HIV-infected children and adolescents and healthy controls, using conventional echocardiography along with tissue Doppler imaging and strain analysis by speckle tracking. Simultaneously, measurements of carotid intima-media thickness were performed. RESULTS A total of 64 cases and 58 controls were included, mean age was 13.6 ± 5.4 years and 64% were females. All but 2 patients were on antiretroviral treatment, and 64% had undetectable viral load. HIV-infected patients showed higher intima-media thickness (0.425 ± 0.019 vs. 0.415 ± 0.019 mm, P = 0.003). Statistically significant differences were found between groups in ejection fraction and fractional shortening (66.1% and 36.2% in the HIV-infected group vs. 71.5% and 40.8% in the control group, respectively, P = 0.001), although individual values fell within or near normal ranges. There were no significant differences in diastolic function, tissue Doppler imaging or cardiac strain (longitudinal and rotational) between both groups. No associations were identified between echocardiographic parameters and current CD4+ T-lymphocyte counts, CD4+ T-lymphocyte nadir, HIV viral load, duration or type of antiretroviral treatment regimens. CONCLUSIONS In a context of highly effective antiretroviral treatment, no differences were found regarding cardiac abnormalities using conventional and advanced ultrasound imaging techniques in this cohort of vertically HIV-infected children and adolescents, when compared with healthy controls.

Abstract
OBJECTIVE to determine, by Doppler-echocardiography, the frequency of cardiac diastolic dysfunction in asymptomatic and clinically stable pediatric patients with vertical infection by the human immunodeficiency virus (HIV), from the cardiovascular viewpoint. METHODS this was an observational, prospective, and cross-sectional study, performed at a regional referral clinic for patients with HIV, in a convenience sample of 94 individuals, assessing biventricular diastolic function by Doppler-echocardiography, and weight, blood hemoglobin, and percentage of lymphocytes T-CD4(+). RESULTS fifty patients had diastolic dysfunction. Left ventricular dysfunction occurred in 38.7%, and the predominant type of dysfunction was decreased myocardial compliance. Right ventricular dysfunction was observed in 29.4% of the sample, and abnormal relaxation was the most prevalent type. Simultaneous biventricular dysfunction occurred in 14.1% of the individuals. There was no association between dysfunction and the immune status. CONCLUSIONS diastolic dysfunction occurred, individually or simultaneously, with no association with immune status; decreased myocardial compliance was predominant in the left ventricle, and abnormal relaxation in the right ventricle.

Abstract
BACKGROUND Persons living with human immunodeficiency virus (HIV) are at increased risk of developing cardiovascular disease. Few studies have focused on echocardiographic abnormalities in this population. METHODS China AIDS Clinical Trial 0810 is a prospective, multicenter cohort study of persons living with HIV (PLWH). We performed an echocardiography substudy of 325 PLWH. We examined the prevalence of left ventricular systolic dysfunction (LVSD), diastolic dysfunction (DD), pulmonary arterial hypertension (PAH), and increased left ventricular mass (ILVM) in antiretroviral therapy (ART)-naive PLWH at baseline and week 48 after initiation of ART. RESULTS Compared with age- and sex-matched healthy controls, PLWH had a higher prevalence of DD (16.5% vs 7.2%, P < .027) and a marginally significant higher prevalence of LVSD (7.3% vs 2.1%, P = .056). The increase in the prevalence of DD from baseline to week 48 in PLWH was marginally significant (P = .056). No significant difference was observed in the prevalence of LVSD, PAH, or ILVM at baseline and week 48 in PLWH. In logistic regression analysis of all participants, age was significantly associated with LVSD; HIV infection, age, and hypertension were associated with DD whereas HIV infection and hypertension were associated with ILVM at baseline. Logistic regression analysis of PLWH showed that only age was significantly associated with LVSD and DD. CONCLUSIONS The prevalence of echocardiographic abnormalities was significantly higher in ART-naive PLWH than in controls. HIV infection was significantly associated with cardiac abnormalities. No significant change in echocardiographic abnormalities was observed after 48 weeks of ART. Longer-term prospective studies are warranted.

Abstract
BACKGROUND Individuals with HIV infection and peripheral metabolic complications have impaired basal myocardial insulin sensitivity that is related to left ventricular (LV) diastolic dysfunction. It is unknown whether interventions shown to be effective in improving peripheral insulin sensitivity can improve basal myocardial insulin sensitivity and diastolic function in people with HIV and peripheral metabolic complications. OBJECTIVE In a pilot study, we evaluated whether the peroxisome proliferator-activated receptor-gamma (PPAR-γ) agonist pioglitazone or combined endurance and resistance exercise training improves basal myocardial insulin sensitivity and diastolic function in HIV+ adults with peripheral metabolic complications. DESIGN Twenty-four HIV+ adults with metabolic complications including peripheral insulin resistance were randomly assigned to 4 months of pioglitazone (PIO; 30 mg/d) or supervised, progressive endurance and resistance exercise training (EXS; 90-120 min/d, 3 d/wk). Basal myocardial substrate metabolism was quantified by radioisotope tracer methodology and positron emission tomography (PET) imaging, and LV function was measured by echocardiography. RESULTS Twenty participants completed the study. Neither PIO nor EXS resulted in a detectable improvement in basal myocardial insulin sensitivity or diastolic function. Post hoc analyses revealed sample sizes of more than 100 participants are needed to detect significant effects of these interventions on basal myocardial insulin sensitivity and function. CONCLUSIONS PIO or EXS alone did not significantly increase basal myocardial insulin sensitivity or LV diastolic function in HIV+ individuals with peripheral metabolic complications.

Abstract
Use of protease inhibitors (PI) in HIV patients is associated with hyperlipidemia and increased risk of coronary heart disease. Chronic systemic and cardiac effects of ritonavir (RTV), a universal PI booster, and Mg supplementation were examined. RTV was administered (75 mg·kg(-1)·day(-1) po) to Lewis × Brown-Norway hybrid (LBNF1) rats for up to 8 wk; significant increases in plasma triglyceride and cholesterol occurred from 8 days to 8 wk. At 5 wk, the expression of selected hepatic genes (CYP7A1, CITED2, G6PC, and ME-1), which are key to lipid catabolism/synthesis, were altered toward lipogenesis. Dietary Mg supplementation (six-fold higher) completely reversed the altered expression of these genes and attenuated both hypertriglyceridemia and hypercholesterolemia. Neutrophils isolated from the RTV-treated rats displayed a three-fold higher basal and a twofold higher stimulated superoxide production; plasma isoprostane and red blood cell (RBC) GSSG levels were elevated two- to three-fold. All oxidative indices were normalized by Mg supplementation. After 5 wk, RTV caused significant decreases in cardiac left ventricular (LV) shortening fraction and LV ejection fraction; mitral valve early/late atrial ventricular filling (E/A) ratio was reduced accompanied by LV posterior wall thinning. Immunohistochemical staining revealed significant white blood cell (WBC) infiltration (5 wk) and prominent fibrosis (8 wk) in the RTV hearts. Mg supplementation attenuated RTV-induced declines in systolic and diastolic (improved mitral valve E/A ratio) function (>70%), lessened LV posterior wall thinning (by 75%), and substantially decreased the pathological markers. The known clinical hyperlipidemia effects of RTV can be mimicked in the LBNF1 rats; in association, systemic oxidative stress and progressive cardiac dysfunction occurred. Remarkably, Mg supplementation alone suppressed RTV-mediated hyperlipidemia, oxidative stress, and cardiac dysfunction.

Abstract
BACKGROUND Left ventricular hypertrophy (LVH) is a predictor of overall mortality in the general population. The most sensitive diagnostic method is transthoracic echocardiography (TTE). In this study, we describe the prevalence of LVH, and the factors associated with it, in a group of patients with HIV infection. METHODS TTE was offered to all patients attending the outpatient clinic of the Hospital Costa del Sol (Marbella, Spain) between 1 December 2009 and 28 February 2011. The corresponding demographic and clinical data were obtained. The left ventricular mass (LVM) was calculated and indexed by height(2.7). LVH was defined as LVM >48g/m(2.7) in men or >44g/m(2.7) in women. RESULTS We examined 388 individuals (75.5% male, mean age 45.38years). Of these, 76.1% were receiving HAART; 11.9% had hypertension, 6.2% had diabetes mellitus, 23.2% had dyslipidaemia and 53.6% were tobacco users. The risk of cardiovascular disease at 10years (RV10) was 12.15% (95%CI: 10.99-13.31%). 19.1% of these patients had a high RV10. A total of 69 patients (19.8%) presented high LVM. Age, hypertension, dyslipidaemia, RV10 and the use of nevirapine were associated with a greater presence of LVH in the univariate analysis. In the logistic regression analysis performed, the factors retained in the model were the presence of high RV10 (OR: 2.92, 95%CI: 1.39-6.15) and the use of nevirapine (OR 2.20, 95%CI: 1.18-4.14). CONCLUSIONS In this group of patients, the use of nevirapine and the presence of high RV10 were associated with LVH. The use of nevirapine might be related to its prescription for patients with higher RV10.

Abstract
OBJECTIVE Patients with HIV infection are at increased risk for coronary artery disease (CAD), and growing evidence suggests a possible link between vitamin D deficiency and clinical/subclinical CAD. However, the relationship between vitamin D deficiency and coronary artery calcification (CAC), a sensitive marker for subclinical CAD, in those with HIV infection is not well investigated. METHODS CAC was quantified using a Siemens Cardiac 64 scanner, and vitamin D levels and the presence of traditional and novel risk factors for CAD were obtained in 846 HIV-infected African American (AA) participants aged 25 years or older in Baltimore, MD, USA without symptoms or clinical evidence of CAD. RESULTS The prevalence of vitamin D deficiency (25-hydroxy vitamin D <10 ng/mL) was 18.7%. CAC was present in 238 (28.1%) of the 846 participants. Logistic regression analysis revealed that the following factors were independently associated with CAC: age (adjusted odds ratio [OR]: 1.11; 95% confidence interval [CI]: 1.08-1.14); male sex (adjusted OR: 1.71; 95% CI: 1.18-2.49); family history of CAD (adjusted OR: 1.53; 95% CI: 1.05-2.23); total cholesterol (adjusted OR: 1.006; 95% CI: 1.002-1.010); high-density lipoprotein cholesterol (adjusted OR: 0.989; 95% CI: 0.979-0.999); years of cocaine use (adjusted OR: 1.02; 95% CI: 1.001-1.04); duration of exposure to protease inhibitors (adjusted OR: 1.004; 95% CI: 1.001-1.007); and vitamin D deficiency (adjusted OR: 1.98; 95% CI: 1.31-3.00). CONCLUSION Both vitamin D deficiency and CAC are prevalent in AAs with HIV infection. In order to reduce the risk for CAD in HIV-infected AAs, vitamin D levels should be closely monitored. These data also suggest that clinical trials should be conducted to examine whether vitamin D supplementations reduce the risk of CAD in this AA population.

Abstract
Our objective was to determine if the presence of metabolic complications (MC) conveyed an additional risk for left ventricular (LV) dysfunction in people with HIV. HIV⁺ and HIV⁻ men and women were categorized into four groups: (1) HIV⁺ with MC (43±7 years, n=64), (2) HIV⁺ without MC (42±7 years, n=59), (3) HIV⁻ with MC (44±8 years, n=37), or (4) HIV⁻ controls without MC (42±8 years, n=41). All participants underwent two-dimensional (2-D), Doppler, and tissue Doppler echocardiography. Overall, the prevalence of systolic dysfunction (15 vs. 4%, p=0.02) and LV hypertrophy (9 vs. 1%, p=0.03) was greater in HIV⁺ than in HIV⁻ participants. Participants with MC had a greater prevalence of LV hypertrophy (10% vs. 1%). Early mitral annular velocity during diastole was significantly (p<0.005) lower in groups with MC (HIV⁺/MC⁺: 11.6±2.3, HIV⁻/MC⁺: 12.0±2.3 vs. HIV⁺/MC⁻: 12.4±2.3, HIV⁻/MC⁻: 13.1±2.4 cm/s) and tended to be lower in groups with HIV (p=0.10). However, there was no interaction effect of HIV and MC for any systolic or diastolic variable. Regardless of HIV status, participants with MC had reduced LV diastolic function. Although both the presence of MC and HIV infection were associated with lower diastolic function, there was no additive negative effect of HIV on diastolic function beyond the effect of MC. Also, HIV was independently associated with lower systolic function. Clinical monitoring of LV function in individuals with metabolic risk factors, regardless of HIV status, is warranted.

Abstract
BACKGROUND The HIV infection has been associated with an increased incidence of vascular events. Left ventricular mass (LVM) is independently associated with greater overall mortality. Various studies have shown that patients with HIV infection have higher LVM than the uninfected population. We aim to describe the distribution of LVM in an extensive series of patients with HIV infection, and the factors associated with its increase. PATIENTS AND METHODS A cross-sectional study was performed in HIV-infected patients followed in our center from 1 December 2009 to 28 February 2011. A transthoracic echocardiography (TTE) was performed in all patients who gave their consent. Demographic variables, viroimmunological status, cardiovascular risk factors, vascular risk at 10 years (VR10) and history of exposure to antiretroviral drugs were collected. LVM was considered to be the quantitative dependent variable. A univariate analysis was performed, including in the multivariate analysis those variables with P<,05. RESULTS A TTE was performed in 400 patients, and the LVM was calculated in 388. Mean age was 45 years, 75.5 males. Mean LVM was 39.54g/m(2.7)(95% CI: 38.35-40.73). Age, height, body mass index, VR10, hypertension, dyslipidemia, different medications within the cardiovascular area and having taken nevirapine have been used in the history of the patient were associated to greater LVM. In the multivariate analysis, use of nevirapine in the history of the patient and VR10 remained in the model. CONCLUSIONS VR10 may be associated with greater LVM. The relationship with nevirapine may respond to an indication bias.

Abstract
BACKGROUND At least one-third of human immunodeficiency virus (HIV)-infected infants survive to adolescence even without antiretroviral therapy (ART), but are at high risk of complications including cardiac disease. We investigated the characteristics of cardiac disease among adolescents with HIV infection diagnosed in late childhood who were receiving ambulatory HIV care in Harare, Zimbabwe. METHODS Consecutive adolescents with vertically acquired HIV attending 2 HIV outpatient treatment clinics were studied. Assessment included clinical history and examination, and 2-dimensional, M-mode, pulsed- and continuous-wave Doppler echocardiography. RESULTS Of 110 participants (47% male; median age, 15 years; interquartile range, 12-17 years), 78 (71%) were taking ART. Exertional dyspnea, chest pain, palpitations, and ankle swelling were reported by 47 (43%), 43 (39%), 10 (9%), and 7 (6%), respectively. The New York Heart Association score was ≥ 2 in 41 participants (37%). Echocardiography showed that 74 participants (67%) had left ventricular (LV; septal and/or free wall) hypertrophy and 27 (24%) had evidence of impaired LV relaxation or restrictive LV physiology. The estimated pulmonary artery systolic pressure (ePASP) was >30 mm Hg in 4 participants (3.6%); of these 2 also had right ventricular (RV) dilatation. Another 32 participants (29%), without elevated ePASP, had isolated RV dilatation. CONCLUSIONS A significant burden of cardiac disease was seen among adolescents with vertically acquired HIV infection. More than half were asymptomatic yet had significant echocardiographic abnormalities. These findings highlight the need to screen this population in order to better define the geography, natural history, etiopathogenic mechanisms, and management (including the timing and choice of optimal therapeutic ART and cardiac drug interventions) to prevent development and/or progression of HIV-associated cardiac disease.

Abstract
AIMS Human immunodeficiency virus infection (HIV) has been associated with cardiac dysfunction that, if present, can negatively affect morbidity and mortality of HIV-infected patients. Unfortunately, many of the studies on this topic were performed before the highly active antiretroviral therapy (HAART) was established. Thus, we performed a comprehensive meta-analysis to critically appraise the incidence of cardiac dysfunction in HIV-infected pauci symptomatic patients. METHODS AND RESULTS Medline, Cochrane Library, and Biomed Central were systematically screened for studies reporting on systolic and/or diastolic dysfunctions in HIV pauci-symptomatic patients. Baseline treatment and cardiac imaging data were appraised and pooled with random effect methods computing summary. At pooled analysis, including a total of 2242 patients from 11 studies, an overall average incidence of traditional cardiovascular risk factors was observed, while a low rate of previous coronary artery disease was reported. Incidence of systolic and diastolic left ventricular dysfunction was 8.33% (95% CI: 2.20-14.25) and 43.38% (95% CI: 31.73-55.03), respectively. Diastolic dysfunction was graded as first [31.85% (95% CI: 24.85-43.73)], second [8.53% (95% CI: 2.12-14.93)], and third degree [3.02% (95% CI: 1.78-4.27)]. At multivariate analysis, a high sensitivity C-reactive protein level >5 mg/L, active tobacco smoking and previous history of myocardial infarction were predictors of left ventricular systolic dysfunction [odd ratio 1.70 (95% CI: 1.03-2.77); 1.57 (95% CI: 1.03-2.34); and 15.90 (95% CI: 1.94-329.00), respectively]. Hypertension (OR = 2.30; 95% CI: 1.20-4.50) and older age (OR = 2.50 per 10 years increase; 95% CI: 1.70-3.60) were predictors of left ventricular diastolic dysfunction (Figure 3). CONCLUSIONS Systolic and diastolic dysfunction represent a common finding in pauci symptomatic HIV-infected patients, regardless to HAART.

Abstract
OBJECTIVE Abnormalities in left ventricular morphology and function have been reported in HIV-negative infants exposed to antiretroviral therapy (ART) in utero that persists throughout preschool age. The objective of this study was to determine if these abnormalities persist, resolve, or worsen during preadolescence. DESIGN Cross-sectional observation study. METHODS Thirty HIV-negative children born to HIV-positive women and exposed to ART in utero (mean age 8 ± 2 years, 37% female, 74% African-American) and 30 HIV-negative children born to HIV-negative women (mean age 8 ± 3 years, 37% female, 76% African-American) underwent two-dimensional Doppler, tissue Doppler, and strain echocardiography to evaluate left ventricular systolic and diastolic function. RESULTS Weight, body surface area, heart rate and blood pressure were similar between groups. For the ART-exposed group, left ventricular mass index was lower (60 ± 9 vs. 67 ± 12 g/m, P < 0.02) and early diastolic annular velocity was lower (15.0 ± 2.2 vs. 16.3 ± 2.5 cm/s, P < 0.03) compared to controls. Left ventricular systolic function did not differ between groups. Lower maternal third trimester CD4 count was associated with lower early diastolic annular velocity; other non-HIV-related variables including cocaine use and increased maternal age correlated with lower left ventricular mass index. CONCLUSIONS Abnormalities in left ventricular systolic performance previously reported in HIV-negative infants and preschool aged children exposed to ART in utero were not apparent in preadolescent children. Left ventricular diastolic relaxation was reduced compared with controls suggesting residual effects of ART exposure on left ventricular diastolic function. Larger, longitudinal studies are necessary to confirm these observations.

Abstract
OBJECTIVE To establish the relationship between HIV-induced cardiac diastolic dysfunction, immune responses, and virus replication in the heart using the simian immunodeficiency virus (SIV)/macaque model. DESIGN Cardiac diastolic dysfunction is common in HIV-infected individuals including asymptomatic patients and those treated with combination antiretroviral therapy. SIV-infected macaques develop cardiac dysfunction, serving as a useful model to establish mechanisms underlying HIV-induced cardiac dysfunction. To understand the relationship between functional cardiac impairment, viral replication in the heart, and associated host inflammatory responses, cardiac function was evaluated in SIV-infected macaques and functional decline was correlated with features of the host immune response and the extent of viral replication in both the myocardium and plasma. METHODS Cardiac function was evaluated longitudinally in 22 SIV-infected and eight uninfected macaques using mitral inflow and tissue Doppler echocardiography. Myocardial macrophage populations were evaluated by CD68 and CD163 immunostaining. SIV RNA levels in both myocardium and plasma were measured by qRT-PCR. RESULTS Echocardiographic abnormalities developed in SIV-infected macaques that closely resembled diastolic dysfunction reported in asymptomatic HIV-infected individuals. Although CD68 and CD163 were upregulated in the myocardium of SIV-infected animals, neither macrophage marker correlated with functional decline. SIV-induced diastolic dysfunction was strongly correlated with extent of SIV replication in the myocardium, implicating virus or viral proteins in the initiation and progression of cardiac dysfunction. CONCLUSION This study demonstrated a strong correlation between cardiac functional impairment and extent of SIV replication in the myocardium, suggesting that persistent viral replication in myocardial macrophages induces cardiomyocyte damage manifest as diastolic dysfunction.

Abstract
BACKGROUND Growing evidence suggests that vitamin D deficiency Is associated with clinical coronary artery disease (CAD). The relationship between vitamin D deficiency and subclinical CAD in HIV-infected individuals is not well-characterized. METHODS Computed tomographic (CT) coronary angiography was performed using contrast-enhanced 64-slice multidetector CT imaging, and vitamin D levels and the presence of traditional and novel risk factor for CAD were obtained in 674 HIV-infected African American (AA) participants aged 25-54 years in Baltimore, MD, without symptoms/clinical evidence of CAD. RESULTS The prevalence of vitamin D deficiency (25-hydroxy vitamin D <10 ng/mL) was 20.0% (95% confidence interval [CI], 16.9-23.1). Significant (≥50%) coronary stenosis was present in 64 (9.5%) of 674 participants. Multiple logistic regression analysis revealed that male gender (adjusted odds ratio [OR], 2.19; 95% CI, 1.17-4.10), diastolic BP ≥85 mmHg (adjusted OR: 1.94, 95% CI: 1.02 -3.68), low-density lipoprotein cholesterol ≥100 mg/dL (adjusted OR, 1.95; 95% CI, 1.13-3.36), cocaine use for ≥15 years (adjusted OR, 1.77; 95% CI, 1.01-3.10), use of antiretroviral therapies for ≥6 months (adjusted OR, 2.26; 95% CI, 1.17-4.36), year of enrollment after 2005 (adjusted ORs for 2006-2007, 2008-2009, and 2010 were 0.32 [95% CI, 0.13-0.76], 0.26 [95% CI, 0.12-0.56], and 0.32 (95% CI, 0.15-0.65], respectively), and vitamin D deficiency (adjusted OR, 2.28; 95% CI, 1.23-4.21) were independently associated with significant coronary stenosis. CONCLUSIONS Both vitamin D deficiency and silent CAD are prevalent in HIV-infected AAs. In addition to management of traditional CAD risk factors and substance abuse, vitamin D deficiency should be evaluated in HIV-infected AAs. These data support the conduct of a prospective trial of vitamin D in this high-risk patient population.

Abstract
BACKGROUND In the general population, peripheral metabolic complications (MC) increase the risk for left ventricular dysfunction. Human immunodeficiency virus infection (HIV) and combination anti-retroviral therapy (cART) are associated with MC, left ventricular dysfunction, and a higher incidence of cardiovascular events than the general population. We examined whether myocardial nutrient metabolism and left ventricular dysfunction are related to one another and worse in HIV infected men treated with cART vs. HIV-negative men with or without MC. METHODS Prospective, cross-sectional study of myocardial glucose and fatty acid metabolism and left ventricular function in HIV+ and HIV-negative men with and without MC. Myocardial glucose utilization (GLUT), and fatty acid oxidation and utilization rates were quantified using 11C-glucose and 11C-palmitate and myocardial positron emission tomography (PET) imaging in four groups of men: 23 HIV+ men with MC+ (HIV+/MC+, 42 ± 6 yrs), 15 HIV+ men without MC (HIV+/MC-, 41 ± 6 yrs), 9 HIV-negative men with MC (HIV-/MC+, 33 ± 5 yrs), and 22 HIV-negative men without MC (HIV-/MC-, 25 ± 6 yrs). Left ventricular function parameters were quantified using echocardiography. RESULTS Myocardial glucose utilization was similar among groups, however when normalized to fasting plasma insulin concentration (GLUT/INS) was lower (p < 0.01) in men with metabolic complications (HIV+: 9.2 ± 6.2 vs. HIV-: 10.4 ± 8.1 nmol/g/min/μU/mL) than men without metabolic complications (HIV+: 45.0 ± 33.3 vs. HIV-: 60.3 ± 53.0 nmol/g/min/μU/mL). Lower GLUT/INS was associated with lower myocardial relaxation velocity during early diastole (r = 0.39, p < 0.001). CONCLUSION Men with metabolic complications, irrespective of HIV infection, had lower basal myocardial glucose utilization rates per unit insulin that were related to left ventricular diastolic impairments, indicating that well-controlled HIV infection is not an independent risk factor for blunted myocardial glucose utilization per unit of insulin.

Abstract
The high cardiovascular risk of HIV infected (HIV+) patients is still partly unexplained. We aimed to evaluate if HIV infection and highly active antiretroviral therapy (HAART) are linked per se to left ventricular (LV) remodelling, independently of blood pressure (BP) values. We enrolled 4 groups of patients matched by gender, age, body mass index and smoking habit: 30 HIV+ hypertensives, 30 HIV+ normotensives, 30 not-infected (HIV-) hypertensives and 30 HIV- normotensives. HIV+ patients were on chronic HAART. Hypertension was newly diagnosed (≤6 months) and never treated. Each patient underwent blood tests, 24-h BP monitoring and LV echocardiogram. The 4 groups had similar fasting glucose and cholesterol; triglycerides, HOMA index and prevalence of metabolic syndrome were higher in the HIV+ groups. Despite similar 24-h BP values, HIV+ hypertensives had greater LV mass and higher prevalence of preclinical diastolic dysfunction than HIV- hypertensives. Compared to HIV- normotensives, HIV+ normotensives had similar 24-h BP values, but greater LV mass and lower LV diastolic indices, similar to HIV- hypertensives, whose 24-h BP values were higher. Asymptomatic HIV infection and chronic HAART are associated with myocardial hypertrophy and preclinical diastolic dysfunction, independently of BP values.

Abstract
BACKGROUND Clinical and epidemiological evidence suggests that HIV infection and cocaine use are associated with an increased risk of premature atherosclerosis. The underlying mechanisms linking HIV infection and cocaine use with early atherosclerosis remain elusive. METHODS AND RESULTS Endothelin-1 (ET-1) levels in 360 African American participants in Baltimore, Maryland were measured. Quantile regression analysis was performed to examine the associations between ET-1, HIV infection, cocaine use, and other relevant clinical factors. The median of ET-1 in plasma, (1.05 pg/mL with interquartile range: 0.73, 1.40) for those with HIV infection was significantly higher than values for those without HIV infection (0.74 pg/mL with interquartile range: 0.61, 0.93). The median of ET-1 was markedly higher in chronic cocaine users (0.96 pg/mL with interquartile range: 0.71, 1.36) than that in non-cocaine users (0.72 pg/mL with interquartile range: 0.58, 1.06). Multivariate quantile regression suggested that HIV infection and duration of cocaine use were independently associated with plasma ET-1 levels after controlling for potential confounding factors. CONCLUSIONS This study may provide insight into the mechanism of premature atherosclerosis in HIV-infected cocaine users and suggest that measurement of ET-1 in plasma can be used as a marker of early atherosclerosis in HIV infected patients and cocaine users.

Abstract
This study assessed cardiac diastolic dysfunction (DD) in HIV-infected subjects without cardiovascular symptoms in China. Eighty-four HIV-infected patients without cardiovascular symptoms were recruited and compared with 30 HIV-negative control subjects. Cardiac DD was evaluated using echocardiography including tissue Doppler imaging. DD was detected in 47.6% of AIDS patients and 42.8% of HIV-positive patients, which was significantly higher than in HIV-negative controls. After logistic regression analysis, HIV infection was independently correlated with cardiac DD (P < 0.05). Among HIV-positive subjects, logistic regression analysis showed that zidovudine exposure was associated with higher prevalence of DD (P < 0.05). Asymptomatic cardiac DD was observed frequently in HIV-infected subjects. HIV infection itself and zidovudine exposure were correlated with a higher prevalence of cardiac DD.

Abstract
BACKGROUND Although highly active antiretroviral therapy (HAART) has dramatically reduced the morbidity and mortality associated with HIV infection, a number of antiretroviral toxicities have been described, including myocardial toxicity resulting from the use of nucleotide and nucleoside reverse transcriptase inhibitors (NRTIs). Current treatment guidelines recommend the use of HAART regimens containing two NRTIs for initial therapy of HIV-1 positive individuals; however, potential cardiotoxicity resulting from treatment with multiple NRTIs has not been addressed. METHODOLOGY/PRINCIPAL FINDINGS We examined myocardial tissue from twelve CD8 lymphocyte-depleted adult rhesus macaques, including eight animals infected with simian immunodeficiency virus, four of which received combined antiretroviral therapy (CART) consisting of two NRTIs [(9-R-2-Phosphonomethoxypropyl Adenine) (PMPA) and (+/-)-beta-2',3'-dideoxy-5-fluoro-3'-thiacytidine (RCV)] for 28 days. Multifocal infiltrates of mononuclear inflammatory cells were present in the myocardium of all macaques that received CART, but not untreated SIV-positive animals or SIV-negative controls. Macrophages were the predominant inflammatory cells within lesions, as shown by immunoreactivity for the macrophage markers Iba1 and CD68. Heart specimens from monkeys that received CART had significantly lower virus burdens than untreated animals (p<0.05), but significantly greater quantities of TNF-α mRNA than either SIV-positive untreated animals or uninfected controls (p<0.05). Interferon-γ (IFN-γ), IL-1β and CXCL11 mRNA were upregulated in heart tissue from SIV-positive monkeys, independent of antiretroviral treatment, but CXCL9 mRNA was only upregulated in heart tissue from macaques that received CART. CONCLUSIONS/SIGNIFICANCE These results suggest that short-term treatment with multiple NRTIs may be associated with myocarditis, and demonstrate that the CD8-depleted SIV-positive rhesus monkey is a useful model for studying the cardiotoxic effects of combined antiretroviral therapy in the setting of immunodeficiency virus infection.

Abstract
PURPOSE Antiretroviral therapy has improved the prognosis for many individuals with HIV infection. Consequently, HIV infection has become a chronic and manageable disease with increased risk of cardiovascular disease. Isolated diastolic dysfunction (DD) may be the first indication of underlying cardiac disease and an early marker of coronary artery disease. Our aim was to assess the prevalence of DD in HIV-infected patients. METHODS In this cross-sectional cohort study, 698 unselected patients were included. All subjects underwent two-dimensional transthoracic echocardiography with tissue Doppler imaging. RESULTS The prevalence of DD among the HIV-infected patients was 48%. Patients with DD were characterized by older age, higher body mass index, higher total cholesterol, arterial hypertension, and diabetes mellitus. Diabetes mellitus and arterial hypertension were associated with approximately four times the risk for DD (odds ratio [OR] 3.9, 95% CI 1.65-9.17; OR 3.8, 95% CI 2.49-5.71, respectively). Persons with hyperlipidemia were approximately one and a half times more likely to have DD than those without hyperlipidemia (OR 1.5, 95% CI 1.12-2.07). CONCLUSIONS In our study, an impressive high prevalence of DD in HIV-infected patients was demonstrated. Traditional cardiovascular risk factors substantially contributed to the development of DD in the HIV-infected cohort.

Abstract
BACKGROUND Patients with HIV have increased risk for cardiovascular disease, but the underlying mechanisms remain unknown. The purpose of this study was to determine the prevalence of echocardiographic abnormalities among asymptomatic HIV-infected individuals compared with HIV-uninfected individuals. Methods/Results- We performed echocardiography in 196 HIV-infected adults and 52 controls. Left ventricular ejection fraction, left ventricular mass indexed to the body surface area, and diastolic function were assessed according to American Society of Echocardiography standards. Left ventricular mass index was higher in HIV-infected patients (77.2 g/m(2) in patients with HIV versus 66.5 g/m(2) in controls, P<0.0001). Left ventricular ejection fraction was similar in both groups. Eight (4%) of the patients with HIV had evidence of left ventricular systolic dysfunction (defined as an EF <50%) versus none of the controls; 97 (50%) had mild diastolic dysfunction compared with 29% of the HIV-uninfected subjects (P=0.008). After adjustment for hypertension and race, HIV-infected participants had a mean 8 g/m(2) larger left ventricular mass index compared with controls (P=0.001). Higher left ventricular mass index was independently associated with lower nadir CD4 T-cell count, suggesting that immunodeficiency may play a role in this process. After adjustment for age and traditional risk factors, patients with HIV had a 2.4 greater odds of having diastolic dysfunction as compared with controls (P=0.019). CONCLUSIONS HIV-infected patients had a higher prevalence of diastolic dysfunction and higher left ventricular mass index compared with controls. These differences were not readily explained by differences in traditional risk factors and were independently associated with HIV infection. These results suggest that contemporary asymptomatic patients with HIV manifest mild functional and morphological cardiac abnormalities, which are independently associated with HIV infection.

Abstract
The relationship between human immunodeficiency virus (HIV) infection and cardiovascular disease is still under debate, but it appears that the risk of myocardial infarction in those with HIV infection who are receiving highly active antiretroviral therapy (HAART) is increased. There has been less focus, however, on the effect of HIV and HAART on left ventricular function. Evidence from the past 20 years in both Westernized and developing countries has indicated that subclinical left ventricular dysfunction in HIV-infected individuals with and without well-controlled HIV infection is prevalent and may represent emerging cardiac disease. The specific roles of HIV infection and HAART are unclear, but they may exert independent direct and indirect effects on the myocardium. These effects may include chronic inflammation, metabolic complications (ie, insulin resistance, lipotoxicity, dyslipidemia), and mitochondrial toxicity. The objective of this article is to review the evidence for HIV- and HAART-related left ventricular dysfunction in persons infected with HIV.

Abstract
Left ventricular hypertrophy (LVH) is an independent predictor of major cardiovascular events. Cardiovascular risk is increased among human immunodeficiency virus (HIV)-infected patients. To assess LV mass/hypertrophy in HIV infection, 654 women enrolled in the Women's Interagency HIV Study underwent transthoracic echocardiography. There were 454 HIV-infected and 200 uninfected women, mean age 40.8 +/- 9.3 years. LV mass/height(2.7) was similar between the HIV-infected and the HIV-uninfected groups (41.4 +/- 11.1 vs. 39.9 +/- 10.3 g/h(2.7); p = 0.37). The prevalence of LVH was similar between the two groups (LVH by LV mass/height(2.7) criteria 15.0% vs. 13.0%, p = 0.29). Relative wall thickness (RWT), defined as the ratio of LV wall thickness to cavity diameter, was also similar between the HIV-infected and HIV-uninfected groups (0.36 +/- 0.05 vs. 0.37 +/- 0.06, p = 0.16). On multiple linear regression analysis adjusting for age, W/H ratio, triceps skinfold thickness, systolic/diastolic BP, diabetes, hypertension and dyslipidemia; HIV status (b = 2.08, p = 0.02, CI 0.27-3.88); weight (b per kg = 0.15, p < 0.01, CI 0.08-0.22); and smoking duration (b per one-year increase = 0.08, p = 0.03, CI 0.01-0.16) were independent correlates of LV mass/height(2.7) (Model R(2) = 0.20, p < 0.001). Weight (aOR = 1.04, CI 1.01-1.06) and smoking duration (aOR = 1.03, CI 1.01-1.06) were independent correlates of LVH. Being HIV negative, increased age, increased triceps skinfold thickness, and higher W/H ratio were independent correlates of higher RWT. Among HIV-infected women, higher LV mass was not associated with a history of AIDS-defining illness, nadir CD4(+) count <200 cells/microl, or with the duration of highly active antiretroviral therapy (HAART). Women taking NRTIs had higher LV mass. Higher RWT was associated with current CD4(+) count. In conclusion, HIV infection is associated with greater LV mass but not with a higher prevalence of LVH. Among HIV-infected women, RWT, but not LV mass, is associated with the degree of immunosuppression.

Abstract
Combination antiretroviral therapy (ART) has markedly improved survival in HIV-infected patients, but not without significant adverse effects including ART-associated dyslipdemia and insulin resistance, which may in part contribute to an increased risk of cardiovascular events. Other contributing factors to cardiovascular risk may include uncontrolled HIV replication, the effects of HIV and ART on vascular endothelium and inflammatory cytokines. Diastolic dysfunction may be an early sign of cardiovascular disease. Our objective was to determine the prevalence of diastolic dysfunction in HIV-infected patients without cardiovascular symptoms. We enrolled 91 subjects in a cross-sectional study of HIV-infected patients without cardiovascular symptoms between September 2004 and August 2005, to assess whether demographics, HIV-related factors, cardiac risk factors, and ART were associated with diastolic dysfunction. All subjects underwent two-dimensional transthoracic echocardiography with tissue Doppler imaging. Subjects were predominately male with a median age of 38 (interquartile range [IQR]: 33, 42) years and median ART duration 6.15 (IQR: 2.1, 8.4) years. Subjects had low Framingham risk scores. Diastolic dysfunction was observed in 34 patients (37%; 95% confidence interval [CI] 27.4, 48.1). Cardiac risk factors or poor prognostic indicators of AIDS progression were uncommon with no difference between subjects with or without diastolic dysfunction. A nonstatistically significant trend in increased rate of diastolic dysfunction was observed in patients receiving protease inhibitors 1 year or more, 44% versus 28%, respectively (univariate odds ratio 2.02, 95% CI 0.83 to 4.90). This was not observed with prolonged use of either non-nucleoside or nucleoside reverse transcriptase inhibitors. A high prevalence of diastolic dysfunction (37%) in a cohort of HIV-infected patients on ART at low risk for AIDS and cardiovascular disease was demonstrated.

Abstract
Although cardiotoxic effects of highly active antiretroviral therapy (HAART) are a growing concern, there is a lack of prospective studies of subclinical involvement of the heart in human immunodeficiency virus (HIV)-infected patients. This study evaluated noninvasively cardiac morphologic characteristics and function in HIV-positive (HIV(+)) men receiving HAART for > or =2 years with no clinical evidence of cardiovascular disease. Echocardiography at rest, including tissue Doppler imaging and exercise testing, were performed in 30 HIV(+) men (age 42.1 +/- 4.7 years, duration of HIV infection 10.4 +/- 4.7 years, duration of HAART 5.3 +/- 2.1 years) and 26 age-matched healthy controls. At rest, HIV(+) patients had similar left ventricular (LV) mass indexed to height(2.7) (40.6 +/- 9.5 vs 37.5 +/- 9.3 g/m; p >0.05), but a higher prevalence of LV diastolic dysfunction (abnormal relaxation or pseudonormal filling pattern in 64% of patients vs 12% of controls; p <0.001). LV systolic function indexes were significantly lower (ejection fraction 60.4 +/- 8.7% vs 66.9 +/- 6.9%; p <0.01, and tissue Doppler imaging peak systolic velocity 11.4 +/- 1.6 vs 13.5 +/- 2.2 cm/s; p <0.001). Pulmonary artery pressure was higher in patients compared with controls (32.1 +/- 5.4 vs 26.1 +/- 6.5 mm Hg; p <0.001). Exercise testing showed decreased exercise tolerance in HIV(+) patients, with no case of myocardial ischemia. In conclusion, subclinical cardiac abnormalities are frequently observed in HIV(+) patients on HAART. The usefulness of systematic noninvasive screening in this population should be considered.

Abstract
With the improved survival of HIV-infected patients, there are increased concerns about the long-term effects of treatment, including protease inhibitor (PI)-related dyslipidemia. Some 50-70% of patients receiving combination antiretroviral therapy (ART) involving PIs develop lipid abnormalities consisting of elevated levels of total cholesterol, low-density lipoprotein cholesterol and triglycerides that are well-known risk factors for cardiovascular disease. Treatment of HIV dyslipidemia should include lifestyle modifications such as a low-fat diet, increased exercise, reduced alcohol consumption and smoking cessation. In many patients, however, these changes alone will not correct lipid levels. In some patients, changing the PI component of ART to another PI or non-PI and/or lipid-lowering drugs has proven successful. Each approach is associated with advantages and limitations and the need to maintain viral suppression must be balanced with the need to treat abnormal lipid levels.

Abstract
BACKGROUND Studies considering the risk of atherosclerotic disease (AtD) associated with the use of HAART have reported inconsistent results. METHODS Data on antiretroviral therapy (ART) use, risk factors for cardiovascular disease (CVD), AtD and death from other causes in 18 603 HIV-infected patients from two established cohorts were evaluated. The relative hazards of AtD and death from other causes were calculated using a proportional hazards competing risks framework. The impact of protease inhibitor (PI)-containing, non-nucleoside reverse transcriptase inhibitor (NNRTI)-containing or PI + NNRTI-containing regimens on these outcomes were compared to nucleoside reverse transcriptase inhibitor (NRTI)-only regimens or stopping therapy, adjusting for known CVD risk factors. RESULTS In 77 480 person-years of follow-up (median duration 3.49 years) there were 318 AtD events including 92 myocardial infarctions and 2044 deaths. Older age, hypertension, diabetes mellitus, having smoked and HIV disease stage were significantly associated with increased risk of AtD. PI- and NNRTI-containing regimens significantly reduced the joint risk of either AtD or death from other causes compared to NRTI-only or stopping therapy [hazard ratio (HR) for PI-containing ART, 0.76, 95% confidence interval (CI), 0.73-0.78, P< 0.001; NNRTI-containing ART, 0.69, 95% CI, 0.65-0.74; P< 0.001). PI-containing ART was associated with a borderline significant increased risk of myocardial infarction (cause-specific HR for PI-containing ART 1.19, 95% CI, 1.01-1.40, P = 0.04) but not with increased risk of AtD compared to NRTI-only regimens or stopping therapy (cause-specific HR for PI-containing ART, 1.03, 95% CI, 0.95-1.13, P = 0.44). CONCLUSIONS Overall benefits of PI- and NNRTI-based ART in reducing mortality significantly outweigh any risks of AtD in the "short-term" follow-up of this study. Traditional cardiac risk factors play an important role in determining AtD risk status.

Abstract
Antiretroviral drugs are associated with both short-term and long-term adverse events. Like other HIV drugs, protease inhibitors (PIs) may affect metabolic processes influencing body shape and body tissue composition, appearance, bone integrity, and cardiovascular status. However, numerous confounding variables including age, cigarette smoking, body mass index (BMI), duration of HIV infection, degree of immunodeficiency, concomitant antiretroviral agents, extent of previous treatment, and duration of treatment all blur the relationship between PI use and adverse events. Recent data suggest that the early PIs appear to have greater effects on such surrogate markers of disease risk as insulin resistance and cholesterol and triglyceride levels than the recently developed PIs. These data also suggest that evaluation of PIs as a class should be reconsidered and that it is probably not appropriate to extrapolate safety data obtained from individuals treated with first-generation agents in the era of potent combination antiretroviral therapy to those treated with recently developed PIs. Because PIs remain a critical component of successful antiretroviral therapy, evaluation of potential long-term complications with prolonged PI use is essential, as is delineation of the significant differences in safety profiles among individual PIs.
