It is important to advance the knowledge and nursisng care intervention of PTCA. The purposes of this article were to introduce the process of PTCA, the aspects in technique of hemostats, position and time in bed, timing of activated clotting time levels and removal of the sheath. Nursing interventions in promoting patient comfort, maintenance of peripheral tissue perfusion, prevention of complications and maintenance of adequate cardiac output after PTCA; discharge education, including wound care, medication, exercise, risk factors, signs of occlusion and the importance of follow up were also discussed.
