It is unclear if results can be translated directly to the Sub-Saharan Africa context. This study assesses electro- and echocardiographic characteristics in an urban African population, comparing HIV-positive people (treated and not yet treated) with HIV-negative controls.<\/jats:p><\/jats:sec><jats:sec id=\"sec002\"><jats:title>Methods<\/jats:title><jats:p>We conducted a cross-sectional study in Johannesburg, South Africa. We enrolled HIV-positive participants from three randomized controlled trials that had recruited participants from routine HIV testing programs. HIV-negative controls were recruited from the community. Data were collected on demographics, cardiovascular risk factors, medical history and electrocardiographic and echocardiographic characteristics.<\/jats:p><\/jats:sec><jats:sec id=\"sec003\"><jats:title>Results<\/jats:title><jats:p>In total, 394 HIV-positive participants and 153 controls were enrolled. The mean age of HIV-positive participants was 40\u00b19 years (controls: 35\u00b110 years), and 34% were male (controls: 50%). Of HIV-positive participants 36% were overweight or obese (controls: 44%), 23% had hypertension (controls: 28%) and 12% were current smoker (controls: 37%). Median time since HIV diagnosis was 6.0 years (IQR 2.3\u201310.0) and median treatment duration was 4.0 years (IQR 0.0\u20138.0), 50% had undetectable viral load. The frequency of anatomical cardiac abnormalities was low and did not differ between people with and without HIV. We observed no relation between HIV or anti-retroviral therapy (ART) and systolic or diastolic heart function. There was an association between ART use and corrected QT interval: +11.8 ms compared to HIV-negative controls (p&lt;0.01) and +18.9 ms compared to ART-na\u00efve participants (p = 0.01). We also observed a higher left ventricular mass index in participants on ART (+7.8 g\/m<jats:sup>2<\/jats:sup>, p&lt;0.01), but this association disappeared after adjusting for CD4 cell count, viral load and HIV-duration.<\/jats:p><\/jats:sec><jats:sec id=\"sec004\"><jats:title>Conclusion<\/jats:title><jats:p>The low number of major cardiac abnormalities in this relatively young, well managed urban African HIV-positive population is reassuring. The increase in corrected QT interval and left ventricular mass may contribute to higher cardiac mortality and morbidity in people living with HIV in the long term.<\/jats:p><\/jats:sec>","DOI":"10.1371\/journal.pone.0244742","type":"journal-article","created":{"date-parts":[[2021,2,2]],"date-time":"2021-02-02T20:41:29Z","timestamp":1612298489000},"page":"e0244742","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":15,"title":["Electrocardiographic and echocardiographic abnormalities in urban African people living with HIV in South Africa"],"prefix":"10.1371","volume":"16","author":[{"given":"Geert V.
