Insights
Cardiac autonomic dysfunction and QT dispersion are common in HIV/AIDS patients, affecting both those with and without AIDS. However, these conditions did not correlate with CD4 count in this study.
Area of Science:
- Cardiology
- Infectious Diseases
- Neurology
Background:
- HIV/AIDS can lead to various complications, including cardiac issues.
- Cardiac autonomic dysfunction and QT dispersion are potential indicators of cardiovascular health in HIV/AIDS patients.
Purpose of the Study:
- To assess cardiac autonomic dysfunction and QT dispersion in newly diagnosed HIV/AIDS patients.
- To investigate the correlation between cardiac autonomic dysfunction and CD4+ T-cell count in HIV/AIDS patients.
Main Methods:
- Prospective study involving 50 HIV-positive patients (25 with AIDS, 25 without AIDS) and 50 healthy controls.
- Autonomic function assessed using Ewing's battery of tests.
- QT dispersion calculated from electrocardiograms.
Main Results:
- Abnormal autonomic dysfunction observed in 16% of AIDS patients and 4% of HIV-positive patients without AIDS.
- Abnormal QT dispersion found in 48% of AIDS patients and 16% of HIV-positive patients without AIDS.
- No statistically significant correlation between cardiac autonomic dysfunction/QT dispersion and CD4+ T-cell count.
Conclusions:
- Cardiac autonomic dysfunction is prevalent in HIV/AIDS patients, irrespective of AIDS status.
- QT dispersion is a sensitive marker for cardiac dysautonomia in this population.
- CD4+ T-cell count does not appear to be a significant predictor of cardiac autonomic dysfunction or QT dispersion in HIV/AIDS.
Objectives:
To evaluate the cardiac autonomic dysfunction and QT dispersion in newly diagnosed HIV/AIDS patients and to correlate the cardiac autonomic dysfunction with CD4 count.
Methods:
It was a prospective study conducted on 50 patients (25 HIV positive without AIDS and 25 HIV with AIDS) and 50 healthy controls in the department of General Medicine, JLN Hospital, Ajmer. Autonomic function was assessed by Ewing battery of autonomic function tests and QT dispersion was calculated.
Results:
In the present study 16% of HIV positive with AIDS had abnormal autonomic dysfunction and 4% of HIV positive without AIDS had abnormal autonomic dysfunction. 48% of patients in AIDS group and 16% of patients in HIV positive without AIDS group showed abnormal QT dispersion. There was no statistically significant correlation with CD4 count.
Conclusion:
Apart from opportunistic infections, autonomic dysfunction itself can contribute to mortality and morbidity in HIV/AIDS patients. Our study showed that cardiac autonomic dysfunction is a common and relevant clinical problem. It is significantly affected in both HIV positive without AIDS and HIV positive with AIDS groups. QT dispersion is a sensitive predictor of cardiac dysautonomia. But there is no statistically significant correlation with CD4 count.

Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
