Illicit drug use can lead to adverse cardiovascular events; it is an additional risk factor for cardiovascular disease. Thus, we sought to determine the association between CVD and drug use in people living with HIV (PLWH) using the FHS 10-year risk.
Methods
Participants were selected from the MASH cohort. Demographics, anthropometrics, bioimpedance analysis, and fasting blood samples were collected by trained personnel. HIV Viral Load (VL, copies/ml) was abstracted from medical charts. Urine toxicology was used to determine current illicit drug use. Descriptive statistics were used to analyze demographics, HIV status, and VL (undetectable VL < 50 copies/ml). CVD (10-year risk) score was calculated using a formula based on CVD risk factors. An independent sample t-test was used to compare the mean CVD risk score between drug users and non-users. Linear regression was used to find an association between drug users and CVD 10-year risk while controlling for sex and infection status.
Results
Participants’ mean age was 54.6 ± 7.9 years (n = 1034), 58% male and 63.8% Black. About 46.8% were PLWH and 90.9% had an undetectable VL. The average CVD 10-year risk of all participants was 15.1% and 49.6% of participants used illicit substances. A univariate linear regression showed a positive association between FHS 10-year risk and marijuana use (b = 2.260 SE = 1.036, 95% CI: 0.227–4.293; P = 0.029). After adjusting for sex and HIV status the association remained significant (b = 2.322 SE = 1.028, 95% CI: 0.304–4.340; P = 0.024). Comparing the mean 10-year risk between groups, a significant difference between marijuana users and non-users was seen regardless of infection status and age (95% CI: −4.293- −0.227; P = 0.029). Separating by sex, only males showed a significant difference in 10-year risk when comparing marijuana users to non-users irrespective of infection status and age (95% CI: −6.394- −0.8373; P = 0.011). No association was determined between 10-year risk and other substances, including cocaine, fentanyl, and amphetamines.
Conclusions
Marijuana use seems to be a strong predictor of CVD risk in minority populations. However, other substances of abuse did not exhibit a cardiovascular effect regardless of HIV status or sex. Further studies are needed to examine the relationship between the use of marijuana and CVD.
