Epidemiological, clinical, and mechanistic studies examining associations between periodontal disease, inflammatory and microbial biomarkers, and cardiovascular outcomes were included. Biomarkers were categorized as inflammatory cytokines, acute-phase proteins, oxidative stress markers, lipid mediators, and microbial indicators. Evidence regarding periodontal therapy and emerging point-of-care diagnostic technologies was also reviewed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Epidemiological studies demonstrate increased risks of coronary heart disease, stroke, and atherosclerosis in individuals with periodontitis, independent of traditional cardiovascular risk factors. Mechanistic evidence indicates that periodontal pathogens and host immune responses promote systemic inflammation, endothelial dysfunction, and atherogenesis. Key biomarkers associated with cardiovascular outcomes include cytokines (IL-1\u03b2, IL-6, TNF-\u03b1, IL-17), acute-phase proteins (C-reactive protein, fibrinogen), matrix-degrading enzymes such as active matrix metalloproteinase-8, oxidative stress markers (myeloperoxidase, malondialdehyde), lipid mediators (lipoprotein-associated phospholipase A2), and microbial markers such as antibodies to\n                      <jats:italic>Porphyromonas gingivalis<\/jats:italic>\n                      .
