In-stent restenosis adalah komplikasi yang dapat terjadi setelah pemasangan stent.Penelitian ini bertujuan untuk mengidentifikasi faktor ? faktor yang berhubungandengan tindakan PCI berulang. Desain penelitian menggunakan desain noneksperimental jenis cross sectional. Responden sebanyak 70 orang, diperolehmelalui teknik consecutive sampling. Analisis data dilakukan secara univariat,bivariat (chi square) serta multivariat (regresi logistik berganda). Hasil penelitianmenunjukkan bahwa riwayat merokok memiliki hubungan yang signifikan danmerupakan faktor dominan dengan tindakan PCI berulang. Implikasi dalamkeperawatan adalah peningkatan peran perawat sebagai pendidik dalammemberikan pendidikan kesehatan tentang pengendalian faktor risiko yaknikebiasaan merokok pada pasien yang terpasang stent dalam mencegah in-stentrestenosis.

ABSTRACT
In-stent restenosis is a complication that can occur after stenting. This study aimedto identify factors related to re-PCI. A non-experimental design with crosssectional approach was used in this research, while 70 respondents were obtainedthrough a consecutive sampling technique. Data analyzed was performed usingunivariate, bivariate (chi square) and multivariate (multiple logistic regression)tests. The results showed that a history of smoking has a significant relationshipwith the re-PCI and history of smoking is the dominant factor associated with re-PCI. Implications of the research to nursing is to improve of the role of nurses aseducators in providing health education to control risk factors, especially smokinghabits in patients who mounted stents in order to prevent in-stent restenosis, In-stent restenosis is a complication that can occur after stenting.
