Contribution of the Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome Epidemic to De Novo Presentations of Heart Disease in the Heart of Soweto Study Cohort

OBJECTIVES: The contemporary impact of the human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) epidemic on heart disease in South Africa (>5 million people affected) is unknown. The Heart of Soweto Study provides a unique opportunity to identify the contribution of cardiac manifestations of this epidemic to de novo presentations of heart disease in an urban African community in epidemiological transition.

METHODS: Chris Hani Baragwanath Hospital services the >1 million people living in Soweto, South Africa. A prospective, clinical registry captured data from all de novo cases of heart disease presenting to the Cardiology Unit during 2006-08. We describe all cases where HIV/AIDS was concurrently diagnosed.

RESULTS: Overall, 518 of 5328 de novo cases of heart disease were identified as HIV-positive (9.7%) with 54% of these prescribed highly active anti-retroviral therapies on presentation. Women (62%) and Africans (97%) predominated with women being significantly younger than men 38 ± 13 vs. 42 ± 13 years (P = 0.002). The most common primary diagnosis attributable to HIV/AIDS was HIV-related cardiomyopathy (196 cases, 38%); being prescribed more anti-retroviral therapy (127/196 vs. 147/322; odds ratio 2.85, 95% confidence interval 1.81-3.88) with higher viral loads [median 110 000 (inter-quartile range 26 000-510 000) vs. 19 000 (3200-87 000); P = 0.018] and a lower CD4 count [median 180 (71-315) vs. 211 (96-391); P = 0.019] than the rest. An additional 128 cases (25%) were diagnosed with pericarditis/pericardial effusion with a range of other concurrent diagnoses evident, including 42 cases (8.1%) of HIV-related pulmonary arterial hypertension. Only 14 of all 581 cases of coronary artery disease (CAD) (2.4%, mean age 41 ± 13 years) were confirmed HIV-positive.

CONCLUSIONS: Cardiac manifestations of HIV/AIDS identified within this cohort were relatively infrequent. While HIV-related cardiomyopathy and pericardial disease remain important targets for early detection and treatment in this setting, HIV-related cases of CAD remain at historically low levels. Vinny Curry Womens Jersey
