Det finns flera studier som visar ett samband mellan hjärtsjukdom och borrelia. Ibland kan allvarliga symtom uppstå relativt tidigt i sjukdomen och det har hänt att unga människor med hastigt uppkommen hjärtsjukdom på väg att opereras eller strax inpå operationen fått diagnosen borrelia, fått behandling och sluppit operation.

Ett aneurysm är ett bråck eller utvidgning på ett blodkärl, om det vidgas för mycket kan blodkärlet spricka. I vissa fall kan aneusysm bildas på något av hjärtats kärl vid borreliasjukdom.

Endokardit är  inflammatoriska förändringar i endokardiet, hjärtats inre ytskikt, med förekomst av påväxter på ytan eller i själva endokardiet och oftast med utbredning till en hjärtklaff, ibland hjärtkamrarnas inre ytskikt eller andra delar av endokardiet. Inflammationen kan uppträda primärt eller som komplikation till annan sjukdom. Endokardit kan uppstå både tidigt och sent i sjukdomsförloppet.
