Cardiovascular diseases are a major cause of morbidity and mortality. Chronic inflammation is an important risk factor for atherosclerosis, and viral infections can cause cardiovascular disease by developing inflammation. Infection with human T-lymphotropic virus (HTLV) is endemic in some parts of the world such as Japan, Africa, Caribbean islands, South America, and Iran. HTLV-1 is an oncogenic retrovirus, and can cause adult T-cell leukemia/lymphoma (ATL or ATLL). It also causes HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP). A number of inflammatory diseases such as uveitis, arthritis, and Sjogren's syndrome are also associated with the virus. A few case reports have shown the direct involvement of the heart in HTLV-1-positive patients who develop ATLL. The purpose of this study was to review the literature relevant with the role of HTLV in cardiovascular diseases.
