Main common and specific virus mechanisms and complications related to the increased risk of atherosclerosis

Infectious agentMain mechanisms and pathways involvedMain CV complications
HIV

- Presence in the atherosclerotic lesion

- Systemic inflammation/oxidative stress

- Opportunistic infections

- AMI

- High prevalence of traditional CVD risk factors

- Carotid atherosclerosis

- Carotid stiffness

- HF

- Myocardial fibrosis

- T2D

- cART-related adverse cardiometabolic effects

HSV-1 and -2

- Presence in the atherosclerotic lesion

- Systemic inflammation/oxidative stress

- Apoptosis

- Procoagulant effects

- CV mortality

- CAD

- AMI

- Stroke

- Carotid atherosclerosis

CMV

- Presence in the atherosclerotic lesion

SARS-CoV-2

- Direct viral entry through ACE2 receptor (e.g., cardiomyocytes, fibroblasts, endothelial cells)

- Systemic inflammation/cytokine storm

- Hypercoagulability, thrombosis

- Local inflammation (myocardial inflammation-myocarditis, cardiac fibrosis, myocyte apoptosis)

- Plaque destabilization

- Stress, anxiety, psycho-emotional status

- Hypoxia-induced injury (myocardial oxygen demand/supply mismatch)

- Endothelial dysfunction

- Catecholamine stress response

- HF

- Ventricular hypertrophy

- Ventricular dilation

- AMI

- Fibrosis

- Myocarditis

- T2D

CAD: coronary artery disease; AMI: acute myocardial infarction; ACE: angiotensin-converting enzyme; cART: combined antiretroviral therapy; HF: heart failure
