Abstract
Human immunodeficiency virus (HIV) infection represents a major cardiovascular risk factor, and the cumulative cardiovascular disease (CVD) burden among aging people living with HIV (PLWH) constitutes a leading cause of morbidity and mortality. To date, CVD risk assessment in PLWH remains challenging. Therefore, it is necessary to evaluate and stratify the cardiovascular risk in PLWH with appropriate screening and risk assessment tools and protocols to correctly identify which patients are at a higher risk for CVD and will benefit most from prevention measures and timely management. This review aims to accumulate the current evidence on the association between HIV infection and CVD, as well as the risk factors contributing to CVD in PLWH. Furthermore, considering the need for cardiovascular risk assessment in daily clinical practice, the purpose of this review is also to report the current practices and novel perspectives in cardiovascular risk assessment of PLWH and provide further insights into the development and implementation of appropriate CVD risk stratification and treatment strategies, particularly in countries with high HIV burden and limited resources.

Abstract
Incidence of noncommunicable diseases (NCDs), including cardiovascular disease (CVD), cirrhosis, and non-AIDS-defining cancers (NADCs), have been associated with HIV viremia, CD4 cell counts, and CD4/CD8 ratio in persons living with HIV (PLWH). This study examined the importance of these markers to mortality risk following NCD diagnosis. We examined factors associated with mortality following incident CVD, cirrhosis, or NADCs in a clinical cohort of PLWH between 1998 and 2015. We calculated Kaplan-Meier estimates and used multivariable Cox proportional hazard models. We included 341 patients with NCDs (CVD = 169, cancer = 103, and cirrhosis = 67), of whom 129 died. Median age at NCD diagnosis was 49 years and median proportion of time before NCD with virologic suppression was 64%. Median survival after CVD was longer than for cancer or cirrhosis (11.6 years vs. 4.8 and 3.4 years, respectively; log rank test p < .001). In multivariable Cox proportional hazard models, higher CD4/CD8 ratio preceding NCD (adjusted hazard ratio [aHR] per 0.1 increase = 0.92 [95% confidence interval 0.85-0.99]) and higher CD4 nadir (aHR per 100 cells/μL = 0.84 [0.72-0.97]) were associated with decreased mortality risk. Neither CD4 cell count before NCD nor HIV viremia was statistically associated with mortality in adjusted models. When restricted to 116 patients with virologic suppression for ≥80% of time before NCD, only CD4 nadir was associated with mortality risk. Low CD4/CD8 ratio and CD4 nadir were associated with increased mortality risk after NCD, suggesting that prior immunosuppression or ongoing immune imbalance remain important for outcomes following serious NCDs.

Abstract
As early and effective antiretroviral therapy has become more widespread, HIV has transitioned from a progressive, fatal disease to a chronic, manageable disease marked by elevated risk of chronic comorbid diseases, including cardiovascular diseases (CVDs). Rates of myocardial infarction, heart failure, stroke, and other CVD manifestations, including pulmonary hypertension and sudden cardiac death, are significantly higher for people living with HIV than for uninfected control subjects, even in the setting of HIV viral suppression with effective antiretroviral therapy. These elevated risks generally persist after demographic and clinical risk factors are accounted for and may be partly attributed to chronic inflammation and immune dysregulation. Data on long-term CVD outcomes in HIV are limited by the relatively recent epidemiological transition of HIV to a chronic disease. Therefore, our understanding of CVD pathogenesis, prevention, and treatment in HIV relies on large observational studies, randomized controlled trials of HIV therapies that are underpowered to detect CVD end points, and small interventional studies examining surrogate CVD end points. The purpose of this document is to provide a thorough review of the existing evidence on HIV-associated CVD, in particular atherosclerotic CVD (including myocardial infarction and stroke) and heart failure, as well as pragmatic recommendations on how to approach CVD prevention and treatment in HIV in the absence of large-scale randomized controlled trial data. This statement is intended for clinicians caring for people with HIV, individuals living with HIV, and clinical and translational researchers interested in HIV-associated CVD.

Abstract
PURPOSE OF REVIEW The objective of this review is to provide an update on the link between HIV infection and cardiovascular disease (CVD). We will focus our review mainly on literature describing clinical CVD events and understudied topics of importance. RECENT FINDINGS Heart failure, peripheral artery disease, and stroke are CVD modalities deserving more attention in the context of HIV infection in the highly active antiretroviral therapy era. Incidence data on clinical CVD from HIV populations in low- and middle-income countries are limited. Multisubstance use is common in HIV, but understudied as a moderator or mediator of the association between HIV and CVD. CVD risk assessment in HIV remains challenging, but new research into novel biomarkers may provide further insights. There is also a need for inclusion of non-biologic factors in our attempts to understand, quantify, and predict CVD risk among PLWHA. Significant attention has been paid to generating and testing hypotheses to understand the mechanisms of myocardial infarction in HIV. Similar attention is deserving for heart failure, PAD, stroke, and cardiovascular disease risk in resource-limited settings and among substance users with HIV.

Abstract
PURPOSE OF REVIEW The purpose of this review is to summarize and synthesize recent data on the risk of ischemic heart disease (IHD) in HIV-infected individuals. RECENT FINDINGS Recent studies in the field demonstrate an increasing impact of cardiovascular disease (CVD) on morbidity and mortality in HIV relative to AIDS-related diagnoses. Studies continue to support an approximately 1.5 to two-fold increased risk of IHD conferred by HIV, with specific risk varying by sex and virologic/immunologic status. Risk factors include both traditional CVD risk factors and novel, HIV-specific factors including inflammation and immune activation. Specific antiretroviral therapy (ART) drugs may increase CVD risk, yet the net effect of ART with viral suppression is beneficial with regard to CVD risk. Management of cardiovascular risk and prevention of CVD is complex, because current general population strategies target traditional CVD risk factors only. Extensive investigation is being directed at developing tailored CVD risk prediction algorithms and interventions to reduce CVD risk in HIV. SUMMARY Increased IHD risk is a significant clinical and public health challenge in HIV. The development and application of HIV-specific interventions to manage CVD risk factors and reduce CVD risk will improve the long-term health of this ageing population.

Abstract
PURPOSE OF REVIEW The aim of this study was to discuss the most recent research in the management of cardiovascular disease (CVD) in people living with HIV (PLWHIV) with a focus on screening, primary and secondary prevention. RECENT FINDINGS The cause of CVD in PLWHIV is complex and multifactorial and creates a demand for a multifaceted approach to screening and prevention. Current screening and management of CVD risk factors in PLWHIV is suboptimal, reasons for this are not clear and the data are still scarce both in the primary and secondary preventive setting. There are no optimal routine risk screening tools available to accurately detect early and subclinical disease; PLWHIV are undertreated with preventive drugs such as statins and aspirin and antihypertensives; there are still no programmes that have been shown significantly efficient over time with regards to improved smoking cessation, increased physical activity and optimal diet, and recent reports call for intensified focus on HIV-positive women as a particularly vulnerable subgroup. SUMMARY There is a need for further studies investigating barriers to optimal CVD risk factor management in PLWHIV and an increased focus of CVD prevention in HIV-positive women.

Abstract
PURPOSE OF REVIEW To summarize recent findings in the pathogenesis of ischemic heart disease (IHD) in people living with HIV (PLWH). RECENT FINDINGS PLWH have an elevated risk of IHD. Although incidence is declining, this condition still represents a major cause of non-AIDS-related mortality. The cause is likely multifactorial: traditional risk factors play an important role and IHD risk might be reduced with greater emphasis on primary prevention. The contribution of specific antiretroviral agents to IHD risk is changing as antiretroviral coverage increases globally and as safer agents have replaced drugs with well-described metabolic toxicities. The beneficial impact of virological suppression on antiretroviral therapy (ART) in reducing IHD is particularly evident in participants with advanced HIV infection and high baseline cardiovascular risk. The association between current abacavir use and myocardial infarction is still unexplained and indicates that mechanisms other than metabolic alterations may underlie IHD in PLWH. Consequently, the contributions of inflammation, subclinical atherosclerosis and endothelial dysfunction are receiving greater attention. SUMMARY Modern ART coupled with intensified efforts towards primary prevention is the cornerstone of IHD risk management in PLWH. The role of chronic inflammation and its optimal management need to be defined.

Abstract
: The last decade has seen a dramatic change in the demographic structure of the population of people living with HIV (PLWH). The majority of PLWH who start treatment with combination antiretroviral therapy now have good virological and immunological responses and this has resulted in improvements in life expectancy. In addition, there have also been continued new HIV diagnoses (and new HIV infections) in those aged more than 50 years. The average age of those attending HIV clinics has therefore increased, with this trend expected to continue into the future. As the cohort of PLWH has aged, so the spectrum and burden of age-associated noncommunicable comorbidities (AANCCs) in the cohort has increased. PLWH are likely, therefore, to have increased healthcare needs for the foreseeable future. Although it appears that the average age at diagnosis of several AANCC is lower in PLWH, current evidence remains insufficient to demonstrate that HIV infection leads to either accelerated or accentuated aging. The results from several well designed longitudinal cohorts, with appropriately matched control groups, will provide more robust evidence to confirm a potential impact of HIV on the incidence of these AANCC. However, regardless of the impact of HIV itself, the role of other, non-HIV, factors is becoming increasingly important, with coinfection with other viral infections and lifestyle factors playing an increasing role in the development of many AANCC. It is likely that attempts to reduce smoking prevalence and obesity may be associated with important reductions in the incidence of some of these events in the future.

Abstract
: Populations living with HIV who access effective antiretroviral therapies are ageing and thus facing chronic disease-related comorbidities. Cardiovascular disease is now a leading cause of morbidity and mortality in the HIV population as in the general population. The increased incidence of cardiovascular complications experienced by the HIV population is due to physiological aging and consequently the increased risk of hypertension, diabetes, and renal failure. Whether HIV itself is an additive and independent risk factor for cardiovascular disease (CVD) remains a central question. If and how HIV impacts the ageing process is an important and related question. The purpose of the present review is to highlight the risk of CVD in the ageing HIV population, particularly concerning atherosclerotic CVD (ASCVD) and heart failure, and to address effective CVD prevention in an aging HIV population at risk of poly-pharmacy.
