Oral dysbiosis refers to theimbalance between symbionts and pathobionts in the oralcavity, posing potential threats to host cardiovascularhealth. Importantly, oral dysbiosis promotes cardiovascular pathophysiology through different mechanisms.Although overgrowth of certain pathogenic bacteria havebeen indicated in some cardiometabolic diseases, it is stillpremature to consider oral microbiome as a suitable predictor for non-invasive diagnostic purpose. However, targeting oral microbiome might still provide preventive andtherapeutic insights on cardiovascular diseases. Furtherextensive efforts are needed to deepen our understandingon oral-cardiovascular connection in the context of diagnostic and therapeutic perspectives.展开更多
