Cardiovascular Syphilis.

Abstract

Syphilis is a disease caused by the spirochete bacterium Treponema pallidum, progressing in 4 stages: primary, secondary, latent, and tertiary syphilis. In the tertiary stage, patients may develop cardiovascular syphilis, which includes syphilitic aortitis, aortic aneurysm, aortic regurgitation, and coronary artery involvement. These cardiovascular manifestations increase morbidity and mortality during this late stage of syphilis. A recent large-scale, population-wide study has built on our knowledge of cardiovascular syphilis by identifying an increased risk for the development of acute myocardial infarction, heart failure, atrial fibrillation, ischemic stroke, hemorrhagic stroke, venous thromboembolism, and cardiovascular death in syphilis patients. This review discusses the incidence and pathophysiology of these various manifestations of cardiovascular syphilis, while also detailing the latest treatment options and the prognosis of these conditions. The clinical significance of this topic stems from the fact that the incidence of syphilis has spiked in recent years after previously reaching an all-time low in 1999. According to the Centers for Disease Control in the United States, from 2018 to 2022, the reported cases of syphilis increased by 80%. However, the incidence of cardiovascular syphilis has remained the same during this period, likely due to the efficacy of penicillin use early in the infection, preventing the progression of the disease to the tertiary stage. As a result, cardiovascular syphilis mostly remains a disease of the past, with only a few sporadic cases being reported in the literature in recent years.
