However, these HIV+ patients had fewer risk factors than the control group, including less hypertension, diabetes, hyperlipidemia, and other coronary risk factors. HIV+ patients had less atherosclerosis but higher degree of large thrombus burden. Stents were used to a similar degree in the HIV+ and HIV− groups. |
