Toxic shock syndrome: A rare complication to enhanced external counterpulsation.

Enhanced external counterpulsation (EECP) is known to reduce angina pectoris in patients in whom revascularization is not possible. The therapy is associated with few adverse effects. A case with a previously unknown complication - toxic shock syndrome - that occurred twice in an EECP-treated patient is described. Toxic shock syndrome initially resembles the state of septic shock. Early recognition of the syndrome and initiation of therapy is of vital importance to prevent rapid progression and a possibly fatal outcome. Awareness of this condition among cardiologists offering EECP is essential.
