Proposed link between chronic infection and heart aging
The abstract notes that cardiovascular diseases are the leading cause of global mortality and that advanced age is the most significant risk factor. It proposes that chronic infections with viruses, bacteria or parasites that evade clearance could act as catalysts for cardiac decline by prematurely inducing aging phenotypes. This is presented as a perspective, not as an established causal finding.

Proposed mechanisms: inflammation, senescence and remodeling
According to the abstract, persistent infections create a state of permanent inflammaging, a chronic low-grade inflammatory environment with ongoing cytokine signaling and leukocyte infiltration. Mechanistically, it proposes that chronic infection disrupts mTOR signaling and impairs autophagy, triggering cardiomyocyte senescence, and drives mitochondrial dysfunction and excess reactive oxygen species, leading to oxidative DNA damage and metabolic exhaustion. Structurally, it proposes that immune subversion via macrophage polarization and autoimmunity accelerates left ventricular hypertrophy, myocardial remodeling and interstitial fibrosis.

Abstract-only perspective without reported data
The text is a perspective arguing that chronic infection be characterized as a modifiable driver of biological aging, so that anti-infective strategies could be prioritized in cardiovascular longevity and geriatric care. The abstract reports no study design, sample, follow-up or measured outcomes, and the full text was not reviewed. The proposed mechanisms and the framing of infection as modifiable are suggestions, not demonstrated causal effects in people.
