Association between statin use, atherosclerosis, and mortality in HIV-infected adults.

ABSTRACT:

Background

While HIV infection is associated with increased cardiovascular risk, benefit from statin is not well established in HIV-infected adults. We assessed whether statins are associated with a decrease in carotid artery intima-media thickness (cIMT) progression and all-cause mortality in HIV-infected adults who are at elevated ASCVD risk and recommended for statins.

Methods

Carotid IMT was measured at baseline and follow-up in 127 HIV-infected adults who meet ACC/AHA criteria to be on statins. Inverse probability of treatment weighting (IPTW) was used to address selection bias. Multivariable models were used to control for baseline characteristics.

Results

28 subjects (22%) were on statins and 99 subjects (78%) were not. Mean cIMT at baseline was 1.2 mm (SD = 0.34) in statin users and 1.1 mm (SD = 0.34) in non-users, and the multivariable adjusted difference was 0.05mm (95%CI -0.11, 0.21 p = 0.53). After 3.2 years of follow-up, average cIMT progression was similar in statin users and non-users (0.062mm/yr vs. 0.058 mm/yr) and the multivariable adjusted difference over the study period was 0.004 mm/yr (95% CI -0.018, 0.025, p = 0.74). All-cause mortality appeared higher in non-statin users compared with statin users, but the difference was not significant (adjusted HR = 0.74, 95%CI 0.17-3.29, p = 0.70).

Conclusion

In a HIV cohort who had elevated ASCVD risk and meet ACC/AHA criteria for statins, treatment with statins was not associated with a reduction in carotid atherosclerosis progression or total mortality. Future studies are needed to further explore the impact of statins on cardiovascular risk in the HIV-infected population.

Project description:ImportanceLimited studies have investigated the association between statin use and progression of arterial stiffness, a key player in the pathophysiology of cardiovascular disease.ObjectiveTo examine the association between statin use and progression of arterial stiffness in Chinese adults with high atherosclerotic risk measured by brachial-ankle pulse wave velocity (baPWV).Design, setting, and participantsThis retrospective cohort study enrolled 5105 adults with high atherosclerotic risk from the Kailuan General Hospital from 2010 to 2020. Data were analyzed from February 2021 to April 2022.ExposuresStatin use information was retrieved from electronic medical records from 2010 to 2020, and statin users were those who have been prescribed any statin medications at least 6 months before baPWV measurements. Statin users were 1:1 matched with non-statin users by propensity score method.Main outcomes and measuresProgression of baPWV was assessed using the absolute difference between baseline and follow-up baPWV, divided by the follow-up time in years. Multivariable linear regression models were used to estimate the association between statin use and arterial stiffness.ResultsAmong 5105 adults with assessment of baPWV (mean [SD] age: 60.8 [9.7] years; 3842 [75.3%] men and 1263 [24.7%] women), 1310 statin users were matched with 1310 non-statin users (mean [SD] age, 63.2 [9.3] years). Compared with non-statin users, statin users were associated with significantly lower baPWV at baseline (difference: -33.6 cm/s; 95% CI, -62.1 to -5.1 cm/s). Among 1502 adults with repeated assessment of baPWV, 410 statin users were matched with 410 non-statin users (mean [SD] age, 62.9 [9.2] years). Compared with non-statin users, statin users had significantly slower progression of baPWV (difference, -23.3 cm/s per year; 95% CI, -40.6 to -6.0 cm/s per year) during a mean (SD) follow-up of 4.8 (2.7) years. A significantly slower progression of baPWV was observed in continuous statin users (difference, -24.2 cm/s per year; 95% CI, -42.2 to -6.3 cm/s per year) and high adherent users (difference, -39.7 cm/s per year; 95% CI, -66.9 to -12.4 cm/s per year), but not in discontinued users (difference, -17.3 cm/s per year; 95% CI, -52.4 to 17.8 cm/s per year) and low adherent users (difference, -17.9 cm/s per year; 95% CI, -36.5 to 0.7 cm/s per year), compared with non-statin users.Conclusions and relevanceIn this cohort study, statin use was associated with slower progression of arterial stiffness in Chinese adults with high atherosclerotic risk.
