Overview
Epidemiology of cardiovascular disease in the setting of HIV
Monitoring and assessing CVD risk in HIV-infected pts
Inflammatory markers and imaging techniques and how they help elucidate effects of ART on CVD risk
Role of antiretrovirals in CVD risk

Epidemiology of CVD in the Setting of HIV

Rates of CVD are Higher in HIV-Positive Pts HIV associated with a 50% increased acute MI risk after
adjustment for major traditional risk factors
Increased risk remained among those with well-treated HIV
Impact of HIV on risk comparable to traditional risk factors including HTN, DM, and hyperlipidemia
Drivers of CVD in HIV may include a combination of factors including a higher prevalence of traditional (eg, smoking) and nontraditional (eg, stress) risks, the effects of ART, and the effects of HIV itself

The Link Between HIV and CVD
Rate of acute MI higher in HIV-positive pts[1]
HIV infection is a risk factor for ischemic stroke[2]

CVD and Mortality in HIV
Second leading non-HIV cause of death in US (~ 15%)[1] and third in Europe (~ 8%)[2]
Deaths due to CVD range from 6% to 15% in different cohorts[1-4]
As HIV-related deaths has decreased, rate of CVD death has increased[5]
– However, absolute rates of MI and stroke have declined with CVD risk factor reduction, use of ART regimens with better lipid effects, and improvements in immunocompetence[6-9]
In the US, HIV-infected individuals hospitalized for MI
– Have a higher mortality compared with controls (HR: 1.38; P = .04)
– Have lower rates of procedures[10]

Sudden Cardiac Death in HIV
HIV-positive pts (n = 2860) at San Francisco General Hospital between 2000-2009 – 230 deaths; 30 (13%) were SCD
SCDs accounted for 86% of all cardiac deaths (30 of 35) HIV SCD rate: 2.6/1000 person-yrs (> 4 times general population)
Tseng ZH, et al. J Am Coll Cardiol. 2012;59:1891-1896.

Aspirin and CVD
Secondary prevention: Pts with established CAD, TIA/CVA: dose 75 mg-162 mg/day (up to 325 mg for some pts)[1]
– Definitive benefit in MI, stroke, and CV death
Primary prevention less clear: “Consider 75-162 mg/day for pts at higher risk, especially those with 10-yr risk of CHD ≥ 10% whose risk of bleeding is not increased”[2]
– Reduces risk of first MI
– No reduction in rates of stroke or CV death
– Balance increase bleeding vs benefit

Plasma IL-6 Levels Correlated With Incidence of Mortality SMART and ESPRIT trials
19,000 person-yrs of follow-up among 4304 pts (median age: 42 yrs; median CD4+ cell count: 526; 77% men)
– 157 all-cause deaths
– 117 non-AIDS deaths
– 101 progressions to AIDS
– 121 CVD
– 99 NADM
Baseline plasma IL-6 was a stronger predictor of all cause mortality and many fatal non-AIDS events than D-dimer and hsCRP
Adjustment attenuated the associations but IL-6 remained significant including for CVD

Role of Monocytes in Atheromatous Plaque Development HIV in conjunction with pro-atherogenic lipids up-regulates

HIV activates monocytes
– Increase monocyte transmigration
– Increase uptake of oxLDL
– Promote differentiation into foam cells
– And contribute to atherosclerotic plaque formation

DHHS Guidelines: Factors to Consider When Selecting an Initial ART Regimen When selecting a regimen for an individual pt, a number of
pt and regimen specific characteristic should be considered, with the goal of providing a potent, safe, tolerable, and easy to adhere to regimen for the pt in order to achieve sustained virologic control
– CVD is one of several specific comorbidities listed among those to consider
– In pts with high cardiac risk, consider avoiding ABC- and LPV/RTV-based regimens
– Associated with increased cardiovascular risk in some studies

What Is the Role of Statins in HIV-Infected Pts With CVD?

Randomized Trial of Statin Therapy and Coronary Plaque Progression Randomized 12-mo trial in HIV+ pts
on stable ART with LDL < 130 and ≥ 1 coronary plaque
– Atorvastatin 20 mg ( to 40 mg at 3 mos) (n = 19) vs
– Placebo (n = 21)
Statin therapy reduced progression of coronary plaques
– Reduced overall plaque volume, including lipid-laden plaques
– Reduced high-risk morphology plaques
Statin therapy safe and well tolerated

Conclusions: Managing CV Risk in HIV Pts
Rates of CVD higher in HIV-infected pts vs general population
CVD risk can be assessed by considering
– Traditional risk factors
– HIV-related factors
Starting ART early can mitigate CV risk even though certain ART drugs may increase lipids
Statins have been shown to be effective in reducing CV risk in pts without HIV infection and should be used as indicated in HIV-infected pts
