Latar Belakang : Morbiditas pasca operasi bedah pintas koroner BPAK masih cukuptinggi. Hal ini disebabkan karena adanya peningkatan inflamasi 48 ndash; 72 jam pasca BPAK danpeningkatan pada sistem renin angiotensin dan aldosteron RAAS. Penyekat EKA diketahuidapat menghambat RAAS dan inflamasi. Namun belum ada penelitian yang membuktikanbahwa penyekat EKA dapat menurunkan inflamasi pada pasien pasca BPAK Tujuan : Mengetahui efek captopril dalam menurunkan inflamasi yang diukur menggunakanhsCRP pada pasien yang menjalani BPAK elektif. Metode : Penelitian ini merupakan studi kohort prospektif. Dilakukan di Rumah SakitJantung dan Pembuluh Darah Harapan Kita RSJPDHK pada subyek yang menjalani BPAKelektif. Durasi penelitian dilakukan pada bulan Mei hingga Oktober 2016. Subyek dibagidalam dua kelompok yaitu kelompok yang mendapatkan captorpil pasca BPAK dan tanpacaptopril. Dilakukan pemeriksaan hsCRP serial sebanyak tiga kali yaitu sebelum operasi,hari ketiga pasca operasi dan sebelum pulang rawat. Hasil Penelitian : Terdapat total 85 subyek, 49 subyek pada kelompok mendapat captoprildan 36 subyek pada kelompok tanpa captopril. Pemeriksaan hsCRP sebelum operasi dan H 3pasca BPAK menunjukkan tidak ada perbedaan pada kedua kelompok. Pemeriksaan hsCRPH 6 pasca BPAK menunjukkan hsCRP pada kelompok yang mendapatkan captopril lebihrendah 31,4 mg/L 10,5 ndash; 154 vs 46,7 mg/L 10,3 ndash; 318 dengan nilai signifikansi P=0,018. Kesimpulan : Subyek yang mendapatkan captopril mempunyai tingkat inflamasi yang lebihrendah pada H 6 pasca BPAK yang dinilai dengan hsCRP dibandingkan kelompok yangtidak mendapat captopril. ......Background Postoperative morbidity of coronary artery bypass surgery CABG is fairlyhigh.

Latar Belakang: Proprotein convertase subtilisin kexin-9 PCSK-9 merupakan protein yang menghancurkan reseptor low density lipoprotein LDL sehingga penurunan kadarnya dapat menurunkan kadar LDL. Sebagai bagian dari pencegahan sekunder, latihan resistensi direkomendasikan pada pasien pasca bedah pintas arteri koroner BPAK. Tujuan: Mengetahui efek tambahan latihan resistensi terhadap kadar PCSK-9 pada pasien pasca bedah pintas arteri koroner yang menjalani rehabilitasi fase II. Metode: Studi eksperimental randomisasi acak tersamar tunggal membagi 87 pasien pasca BPAK menjadi dua kelompok. Kelompok kontrol n=43 adalah pasien yang menjalani rehabilitasi fase II standar sementara kelompok intervensi n=44 adalah pasien yang menjalani rehabilitasi fase II ditambah dengan latihan resistensi tersupervisi. Kadar PCSK-9 diperiksa sebelum dan sesudah rehabilitasi fase II pada kedua kelompok. Hasil: Setelah menyelesaikan rehabilitasi fase II, didapatkan perbedaan kadar PCSK-9 yang bermakna antara kelompok kontrol dan intervensi 377,1 SD 125 vs 316,6 111,1 ng/ml, ?= -60,5 ng/ml, 95 CI -7,5 -113,4, p=0.026. Tidak didapatkan perbedaan bermakna pada kadar LDL p=0,07, kolesterol total p=0,99, high density lipoprotein HDL p=0,44, dan trigliserid p=0,56 antara kedua kelompok pada akhir rehabilitasi fase II. Kesimpulan: Tambahan latihan resistensi dapat menurunkan kadar PCSK-9 secara bermakna pada pasien pasca bedah pintas arteri koroner yang menjalani rehabilitasi fase II. ......Background: Pro protein Convertase Subtilisin Kexin 9 PCSK 9 is a protein degrading low density lipoprotein LDL receptor that lower LDL. As secondary prevention, resistance training is recommended after coronary artery bypass surgery CABG as a complement to aerobic exercise. Objective: To determine the effects of additional resistance training on PCSK 9 levels and lipid profile in post CABG patients who undergo phase II cardiac rehabilitation. Methods: A single blinded randomized clinical trial of 87 post CABG patients was devided into two groups. The control group n 43 consisted of patients who received standard phase II cardiac rehabilitation while intervention group n 44 received standard program and supervised resistance training. PCSK 9 level and lipid profile examination were performed pre and post training. Results: After completion of phase II cardiac rehabilitation, mean PCSK9 levels in intervention group decrease significantly compared to control group control vs intervention, 377,1 SD 125 vs 316,6 111,1 ng ml, 60,5 ng ml, 95 CI 7,5 113,4 , p 0.026 . Nonetheless, there are still no significant changes in terms of LDL level p 0,07 , total cholesterol p 0,99 , high density lipoprotein p 0,44 and triglyseride levels p 0,56 pre and post intervention between two groups. Conclusion: The additional resistance training can reduce significantly PCSK 9 levels in patients after CABG surgery who underwent phase II cardiac rehabilitation.

Pendahuluan: Pasien pasca Bedah Pintas Arteri Koroner (BPAK) dapat mengalami penurunan kapasitas fungsional dan produktivitas. Hal ini dikarenakan adanya penurunan curah jantung dan penghancuran protein otot (aktin dan miosin). Latihan berjalan dilakukan untuk meningkatkan pompa jantung dan keseimbangan metabolisme. Penelitian ini bertujuan untuk menilai pengaruh latihan berjalan terhadap kapasitas fungsional dan produktivitas ada pasien pasca BPAK. Metode: Penelitian ini menggunakan Randomized Controlled Trial (RCT) dengan single blind pada outcome assessor. Jumlah responden pada penelitian ini berjumlah 42 orang yang dibagi menjadi 21 orang di kelompok intervensi maupun kontrol. Hasil: Penelitian ini menunjukkan hasil adanya pengaruh yang bermakna antara latihan berjalan terhadap kapasitas fungsional (0,008<0,05), gangguan dalam bekerja (0,011<0,05), dan gangguan aktivitas(0,044<0,05). Hasil juga menunjukkan tidak adanya perbedaan yang bermakna antara latihan berjalan terhadap kehilangan waktu kerja (0,967>0,05) dan gangguan pekerjaan keseluruhan (0,696). Diskusi: Latihan berjalan meningkatkan pompa jantung dan metabolisme. hal tersebut meningkatkan pengeluaran Adenosine Triphospat (ATP) sehingga meningkatkan kapasitas fungsional dan produktivitas pada pasien. Kesimpulan: Latihan berjalan meningkatkan kapasitas fungsional dan produktivitas pada pasien pasca BPAK. ......Introduction: Patients after coronary artery bypass graft (CABG) may experience reduced functional capacity and productivity. This is due to decreased cardiac output and destruction of muscle proteins (actin and myosin). Walking exercise is performed to improve cardiac pump and metabolic balance. This study aims to assess the effect of walking training on functional capacity and productivity in patients after BPAK. Methods: This study used a Randomized Controlled Trial (RCT) with a single blind on the outcome assessor. The number of respondents in this study amounted to 42 people who were divided into 21 people in the intervention and control groups. Results: This study showed a significant effect of walking training on functional capacity(0,008<0,05), work interference(0,011<0,05), and activity interference(0,044<0,05). The results also showed no significant difference between walking training on lost work time (0,967>0,05)and overall work interference(0,696>0,05).

Latar Belakang: Penyakit arteri koroner dapat di tata laksana dengan bedah pintas arteri koroner (BPAK) menggunakan mesin pintas jantung paru (PJP) dan fraksi ejeksi (FE) yang rendah berhubungan dengan peningkatan mortalitas jangka pendek dan jangka panjang. Kejadian AKI pascaoperasi BPAK dengan mesin PJP merupakan kejadian yang cukup sering dengan prevalensi bervariasi antara 7,6-48,5%. Patogenesis acute kidney injury(AKI) pascaoperasi jantung bersifat kompleks dan multifaktorial, dengan beberapa mekanismenya melibatkan proses inflamasi, iskemia-cedera reperfusi, dan stres oksidatif. Hingga saat ini belum ada pedoman strategi proteksi ginjal pada operasi BPAK. Glutamin, sebuah asam amino esensial-kondisional memiliki efek anti inflamasi dan anti oksidena melalui induksi heat shock protein (HSP) dan produksi antioksidan glutathione (GSH). Sehingga, dihipotesiskan pemberian glutamin dapat menurunkan kejadian AKI menurunkan gangguan fungsi ginjal pascaoperasi BPAK. Metodologi: Penelitian ini merupakan penelitian kohort retrospektif pada pasien yang menjalani operasi BPAK menggunakan mesin PJP dengan FE rendah. Subjek dibagi menjadi kelompok yang mendapat glutamin intravena praoperasi dan kelompok yang tidak mendapat glutamin. Kejadian AKI 24 jam pascaoperasi, kadar kreatinin serum 24 jam pascaoperasi dan estimated glomerular filtration rate(eGFR) 24 jam pascaoperasi merupakan luaran yang dinilai pada penelitian ini. Hasil: Dari hasil penelitian didapatkan kejadian AKI 24 jam pascoperasi pada kelompok glutamin sebesar 3,3% dan kelompok kontrol 10%. Namun, tidak didapatkan hubungan bermakan kejadian AKI 24 jam pascaoperasi terhadap pemberian glutamin intravena praoperasi (p=0,612). Dari hasil pemeriksaan eGFR 24 jam pascaoperasi, didapatkan rerata kelompok kontrol 57,67 ± 18,86 mL/min/1,73m2dan kelompok glutamin 64,43 ± 17,56 mL/min/1,73m2, namun tidak berbeda bermakna (p=0,156). Dari hasil pemeriksaann kreatinin serum 24 jam pascaoperasi, didapatkan median kelompok kontrol 1,3 (0,87 – 2,68) mg/dL dan kelompok glutamin 1,2 (0,78 – 2,35), namun hasil ini juga tidak berbeda bermakna (p=0,258) Kesimpulan: Pemberian glutamin intravena praoperasi pada pasien dengan fraksi ejeksi rendah yang menjalani BPAK menggunakan mesin PJP, tidak memiliki hubunga bermakna terhadap kejadian AKI dan eGFR serta kadar kreatinin serum 24 jam pascaoperasi. ......Background: Coronary artery disease can be managed by coronary artery bypass graft surgery (CABG) using a cardiopulmonary machine (CPB) and low ejection fraction (FE) is associated with increased short-term and long-term mortality. The incidence of postoperative acute kidney injury (AKI) after CABG using a CPB machine is quite common with a prevalence varying between 7.6-48.5%. The pathogenesis AKI after cardiac surgery is complex and multifactorial, with several mechanisms involving inflammation, ischemia-reperfusion injury, and oxidative stress. Until now, there are no guidelines for kidney protection strategies in CABG surgery. Glutamine, a conditionally essential amino acid has anti-inflammatory and anti-oxidant effects through the induction of heat shock protein (HSP) and the production of the antioxidant glutathione (GSH). Thus, it is hypothesized that the administration of glutamine can reduce the incidence of AKI and decrease renal function impairment after CABG surgery. Methods: This study is a retrospective cohort study in patients who underwent CPA surgery using a PJP machine with low FE. Subjects were divided into groups that received preoperative intravenous glutamine and groups that did not receive glutamine. The incidence of AKI 24 hours postoperatively, serum creatinine levels 24 hours postoperatively and the estimated glomerular filtration rate (eGFR) 24 hours postoperatively were the outcomes assessed in this study. Results:From this study, the incidence of AKI 24 hours postoperatively in the glutamine group was 3.3% and the control group was 10%. However, there was no significant relationship between the incidence of AKI 24 hours postoperatively with preoperative intravenous glutamine administration (p=0.612). From the results of the 24-hour postoperative eGFR examination, the mean of the control group was 57.67 ± 18.86 mL/min/1.73m2 and the glutamine group was 64.43 ± 17.56 mL/min/1.73m2, but not significantly different (p= 0.156). From the results of serum creatinine examination 24 hours postoperatively, the median control group was 1.3 (0.87 – 2.68) mg/dL and the glutamine group 1.2 (0.78 – 2.35) mg/dL, but these results also did not differ significantly (p=0,258)

Edema miokardium dapat menyebabkan disfungsi miokardium. Pada operasi bedah pintas arteri koroner (BPAK), proses inflamasi dan reperfusion injury menyebabkan edema miokardium. Berbagai cara telah dilakukan untuk menghambat edema miokardium namun belum ada yang terbukti efektif. Statin merupakan obat yang memiliki efek pleiotropik sebagai anti inflamasi. Penelitian pada subjek hewan menunjukkan bahwa statin dapat mengurangi edema miokardium. Sebagai respons terhadap kondisi stress, jantung mengeluarkan berbagai sitokin seperti follistatin-like 1 (FSTL1). FSTL1 berperan dalam proses edema miokardium. Untuk mengurangi edema miokardium pasien BPAK dilakukan pemberian Atorvastatin 80 mg selama 2 minggu sebelum operasi. Penelitian dilakukan secara uji klinis tersamar ganda pada pasien berusia 40–65 tahun yang menjalani operasi BPAK. Dilakukan dari Februari 2017 hingga Maret 2018 di rumah sakit jantung dan pembukuh darah Harapan Kita. Subjek penelitian diacak ke dalam dua kelompok, kelompok Atorvastatin dosis 80 mg dan Atorvastatin dosis 10 mg. Pemeriksaan edema miokardium dilakukan dengan MRI pada hari ke-6 pascaoperasi. Pemeriksaan FSTL1, PKA, PKB dan hs-CRP diambil dari plasma darah 1 hari sebelum operasi, hari ke-1 dan hari ke-6 pasca operasi. Parameter MRI yang dinilai adalah nilai T2 relaxation time. Sebanyak 20 pasien termasuk dalam kelompok Atorvastatin 80 mg dan 20 pasien dalam kelompok Atorvastatin 10 mg. Terdapat 7 subjek yang drop out. Pemeriksaan MRI mendapatkan nilai T2 relaxation time yang lebih rendah pada kelompok Atorvastatin 80 mg (50,11 ms vs. 59,03 ms, p = 0,01). Tidak didapatkan korelasi yang bermakna antara FSTL1 dengan T2 relaxation time. Pemeriksaan FSTL1, PKA dan PKB tidak berbeda secara bermakna antara kedua kelompok sedangkan kadar hs-CRP lebih rendah serta bermakna secara statitistik pada kelompok Atorvastatin 80 mg. Simpulan: Pemberian Atorvastatin dosis 80 mg dapat menurunkan kejadian edema miokardium pasca BPAK dan menunjukkan efek antiinflamasi yang lebih baik dari pada Atorvastatin 10 mg. ......Myocardial edema can cause myocardial dysfunction in many pathological states. During coronary artery bypass surgery (CABG), there is inflammatory system activation as well as reperfusion injury which can produce myocardial edema. Many efforts has been applied in order to prevent those process but none has proven effective. Statin is a drug with many pleiotropic effects as anti inflammatory. Animal study revealed that statin can decrease myocardial edema, In response to stress conditions, heart produced many cytokines, such as follistatin-like 1 (FSTL1). FSTL1 has a principal role in reducing myocardial edema. This study tried to find the effectiveness of Atorvastatin 80 mg, also known as high dose statin, in decreasing myocardial edema after CABG surgery. Double blinded clinical trial was performed, in patients 40–65 years of age who underwent CABG surgery. This study was conducted from February 2017 until March 2018 at National Cardiovascular Centre Harapan Kita. Subjects were randomized and divided in two groups, high dose Atorvastatin (80 mg) and low dose atorvasatin (10 mg). Myocardial edema evaluation using magnetic resonance imaging (MRI) was done in day-6 after surgery. FSTL1, PKA, PKB, and hs-CRP were evaluated before surgery, day-1 after surgery, and day-6 after surgery. T2 relaxation time was used as the MRI parameter of myocardial edema. There were 20 patients treated with Atorvastatin 80 mg and 20 patients at Atorvastatin 10 mg. There were 7 subject who dropped out. MRI evaluation found lower T2 relaxation time in high dose group (50,11ms vs. 59,03 ms, p = 0,01). There was no significant correlation between FSTL1 and T2 relaxation time. FTSL1, PKA and PKB in both groups were not statistically different but hs-CRP value was statistically lower in high dose group. Conclusion: Atorvastatin 80 mg can decrease the incidence of myocardial edema after CABG surgery and shows a better anti-inflammatory effect than Atorvastatin 10 mg. The correlation between statin and FSTL1 in term of myocardial edema has not been defined yet.

Latar Belakang. Fibrilasi atrium (FA) awitan dini pascabedah pintas arteri koroner (BPAK) merupakan salah satu komplikasi pascaoperasi yang sering terjadi. Aritmia ini merupakan fenomena sementara dan mayoritas pasien akan mengalami konversi ke irama sinus saat dipulangkan. Meskipun bersifat sementara, FA awitan baru pasca-BPAK berpotensi mengalami rekurensi sehingga dapat meningkatkan risiko mortalitas jangka panjang. Tujuan. Mengetahui peran FA awitan baru pasca-BPAK dalam mempengaruhi kesintasan tiga tahun. Metode. Studi dengan desain kohort retrospektif menggunakan analisis kesintasan yang meneliti 196 pasien yang menjalani BPAK di Rumah Sakit Cipto Mangunkusumo dalam rentang waktu Januari 2012 sampai Desember 2015. Eksklusi dilakukan pada pasien yang memiliki riwayat FA sebelum operasi, menjalani operasi tanpa mesin pintas jantung-paru, dan yang meninggal dalam 30 hari pascaoperasi. Subyek penelitian dibagi menjadi 2 kelompok berdasarkan ada tidaknya FA awitan baru pasca-BPAK, yang selanjutnya ditelusuri status kematiannya dalam tiga tahun sejak operasi. Kurva Kaplan-Meier digunakan untuk menilai kesintasan tiga tahun dan dilakukan uji regresi Cox sebagai uji multivariat terhadap variabel perancu (usia ≥60 tahun, penyakit paru obstruktif kronis, diabetes melitus, gangguan ginjal, dan fraksi ejeksi ventrikel kiri yang rendah) untuk mendapatkan nilai adjusted hazard ratio (HR). Hasil. Sebanyak 29,59% pasien mengalami FA awitan baru pasca-BPAK. Angka mortalitas tiga tahun pasien yang mengalami FA awitan baru pasca-BPAK baru lebih tinggi dibandingkan kelompok yang tidak mengalaminya (15,52% vs 3,62%). Fibrilasi atrium awitan baru pasca-BPAK secara signifikan menurunkan kesintasan tiga tahun (p=0,008; HR. Pada analisis multivariat, FA awitan dini pascaBPAK merupakan faktor independen terhadap penurunan kesintasan tiga tahun (adjusted HR 4,04; IK 95% 1,34-12,14). Simpulan. Fibrilasi atrium awitan baru pasca-BPAK secara independen menurunkan kesintasan tiga tahun.

Background. New-onset atrial fibrillation after coronary artery bypass grafting (CABG) is a common postoperative complication. This arrhytmia considered as temporary phenomenon which the majority are converted back to sinus rhythm when the patients discharged from the hospital. Despite its transience, those arrhythmia can recur and increasing the long term mortality. Objective. To determine the role of new-onset atrial fibrillation after CABG on three year survival. Method. This is a retrospective cohort study using survival analysis of patients who underwent coronary artery bypass grafting since January 2012 to December 2015 at Cipto Mangunkusumo Hospital. Patients who had atrial fibrillation before surgery, who had surgery without cardiopulmonary bypass machine, and who died in 30 days after surgery were excluded. Subjects were divided into two category based of the presence of newonset atrial fibrillation after CABG and the mortality status was followed up until 3 years post-surgery. The Kaplan-Meier curve was used to determine the three-year survival of the patients who had new-onset atrial fibrillation after CABG and Cox regression test used as multivariate analysis with confounding variables in order to get adjusted hazard ratio (HR). Result. New-onset atrial fibrillation after CABG occurred in 29,59% patients. Patients with new-onset atrial fibrillation after CABG had higher three-year mortality (15,52% vs 3,62%). New-onset atrial fibrillation after CABG significantly decreased three-year survival (p=0,008; HR 4,42; 95% CI; 1,49-13,2). In multivariate analysis, it was concluded that new-onset atrial fibrillation after CABG was an independent factor of the three-year survival decline (adjusted HR 4,04; 95% CI; 1,34-12,14). Conclusion. New-onset atrial fibrillation after CABG independently decreased the threeyear survival.

Latar Belakang : Gagal jantung adalah salah satu kondisi dengan morbiditas dan mortalitas yang signifikan. Penyebab paling sering dari masalah gagal jantung adalah iskemia yang disebabkan oleh stenosis pada pembuluh darah koroner. Studi viabilitas adalah metode non-invasif untuk mengidentifikasi sel miokard yang mengalami kondisi stunning maupun hibernating yang mungkin memperoleh manfaat dari revaskularisasi. Studi sebelumnya mencoba melihat perananan viabilitas dengan kesintasan tidak menemukan kaitan antara adanya viabilitas miokard dan juga kesintasan.

Tujuan : Studi ini mencoba membandingkan luaran kejadian kardiovaskular mayor (KKM), mortalitas, rehospitalisasi maupun perbaikan dari fraksi ejeksi pada pasien kardiomiopati iskemik yang akan menjalankan bedah pintas arteri koroner dengan atau tanpa studi viabilitas

Metode : Suatu studi kohort retrospektif dilakukan pada pasien Gagal Jantung dengan Fraksi Ejeksi Menurun yang diputuskan untuk dilakukan Bedah Pintas Arteri Koroner (BPAK) oleh Heart Team Meeting dari Rumah Sakit Jantung dan Pembuluh Darah Harapan Kita. Pasien tersebut dikelompokan kedalam grup yang dilakukan studi viabilitas dan grup yang tidak dilakukan studi viabilitas. Dilakukan follow up pada pasien ini dan dilakukan pencatatan luaran seperti kematian, rehospitalisasi dan juga perbaikan dari fraksi ejeksi.

Hasil : Didapatkan adanya 216 pasien yang menjalankan BPAK dengan dilakukan pemeriksaan viabilitas dan 269 pasien yang menjalankan BPAK tanpa dilakukan pemeriksaan viabilitas. Tidak ada perbedaan yang signifikan secara statistik antara dilakukannya uji viabilitas dengan luaran KKM, mortalitas maupun rehospitalisasi paska dilakukan prospensity score adjustment. Namun, mereka yang dilakukan uji viabilitas lebih banyak yang mengalami perbaikan fraksi ejeksi dibandingkan dengan mereka yang tidak dilakukan uji viabilitas.

Kesimpulan : Tidak ada perbedaan dari KKM, kesintasan maupun rehospitalisasi pada pasien yang menjalankan BPAK dengan data viabilitas dibandingkan dengan mereka yang menjalankan BPAK tanpa data viabilitas. Namun, pasien yang menjalankan BPAK dengan data viabilitas lebih mungkin memiliki perbaikan dari fraksi ejeksi ......Backgrounds : Heart failure with reduced ejection fraction is one of the condition with significant morbidity and mortality. The most common etiology is ischemia caused by stenosis of coronary artery. Viability study is a non-invasive methods to identify which myocardial cells that may experienced stunning or hibernating conditions that may gain benefit from surgical revascularization using coronary artery bypass graft (CABG). Previous study failed to identify the benefit of viability study on major adverse cardiovascular events (MACE), mortality or rehospitalization.

Aim : This study aims to compare the outcome of major adverse cardiovascular events (MACE), mortality, rehospitalization and improvement of ejection fraction in patients with ischemic cardiomyopathy that had coronary artery bypass graft surgery with and without undergoing myocardial viability study.

Methods : A retrospective cohort study were done on patients with heart failure with reduced ejection fraction (HFrEF) that were decided to do coronary artery bypass graft by heart team meeting of National Cardiovascular Center Harapan Kita. The patients were grouped according to whether they undertook viability study or not. Follow up were done on these patients and outcome such as mortality, rehospitalization and improvement of ejection fraction were recorded.

Results : There are 216 patients that had CABG with viability study and 269 patients that had CABG without viability study. There are no statistically significant differences between those undergoing viability study and outcome of MACE, mortality or rehospitalization after prospensity score adjustment. However, those with viability study are more likely to have improvement of ejection fraction compared to those that do not have viability results.

Conclusion : There are no differences in either MACE, survival or rehospitalization in patients that did CABG procedure with viability data compared to those that do not have the data. However, those that have viability data are more likely to have improvement of ejection fraction.

Latar belakang: Bedah pintas arteri koroner (BPAK) adalah sebuah prosedur revaskularisasi koroner. Major adverse cardiovascular event (MACE) yang terjadi pascaprosedur BPAK merupakan kombinasi faktor risiko pasien, intraoperatif, dan pascaoperatif dengan insiden mencapai 33,3% Vasoactive Inotropic Score (VIS) adalah sebuah skor yang menilai jumlah topangan farmakologis kardiovaskular yang awalnya dikembangkan untuk pasien pediatrik. Penelitian ini bertujuan untuk menilai VIS sebagai prediktor terjadinya MACE pascaprosedur BPAK pada pasien dewasa. Metode: Penelitian ini adalah studi observasional analitik dengan desain kohort retrospektif. Jumlah besar sampel minimal adalah 113 dengan metode sampling konsekutif. Variabel yang diteliti adalah usia, jenis kelamin, hipertensi, diabetes melitus, GDS, EF, lama operasi, durasi ventilasi mekanik, jenis operasi, nilai VIS, dan MACE (kematian, infark miokardium, gagal napas, gagal ginjal, sepsis). Batas nilai VIS tinggi yang digunakan adalah ≥10. Hasil: Dari 120 subyek, 34,2% subyek mengalami MACE dan 78,3% memiliki nilai VIS tinggi. Durasi operasi, durasi ventilasi mekanik, jenis operasi, dan nilai VIS berhubungan secara bermakna terhadap MACE. Hubungan nilai VIS dengan ada tidaknya MACE pascaprosedur BPAK memiliki OR 11,6 (IK 95% 4,1 – 32,6, p = 0,001), sensitivitas 48.78% (IK95% 34,25 – 63,52%), dan spesifisitas 92,41% (IK95% 84,4 – 96,47%). Simpulan: VIS secara tunggal belum dapat disimpulkan dapat memprediksi kejadian MACE dan faktor-faktor risiko MACE yang lain juga perlu dipertimbangkan dalam memprediksi MACE. ......Introduction: Coronary artery bypass grafting (CABG) is a coronary revascularization procedure. Major adverse cardiovascular event (MACE) after CABG is a multifactorial process combining patient, intraoperative, and postoperative risk factors with the incidence of 33.3%. Vasoactive Inotropic Score (VIS) is a measurement of pharmacological cardiovascular support that was originally developed for pediatric patients. This study aims to evaluate VIS as a predictor for MACE after CABG in adults. Methods: This study is a retrospective analytical observation study with minimal sample size of 113 subjects. The research variables are age, gender, hypertension, diabetes mellitus, blood glucose, ejection fraction, operation duration, mechanical ventilation duration, operation technique, VIS, and MACE (mortality, myocardial infarct, respiratory failure, kidney failure, sepsis). The cut off point for VIS used in this study is ≥ 10. Results: From 120 subjects, MACE incidence is 34.2% and 78.3% of subjects had high VIS. Operation duration, mechanical ventilation duration, and operation technique were significantly associated with MACE. High VIS were significantly associated with MACE (OR 11.6, CI95% 4.1 – 32.6, p = 0.001). The sensitivity of VIS in predicting MACE is 48.78% (CI95% 34.25 – 63.52%) and its specificity is 92.41% (CI95% 84.4 – 96.47%). Conclusions: VIS alone may not be enough to predict MACE after CABG in adults. Other risk factors should be taken into account to predict MACE.

Untuk analisa hitung jumlah leukosit dilakukan pewarnaan Hematoxyllin eosin pada jaringan vena oleh ahli patologi anatomi. Analisis statistik dilakukan untuk mencari hubungan antara hitung jumlah leukosit jaringan vena dengan time refluks vena saphena magna. Hasil. Analisa statistik dengan Chi square didapatkan perbedaan bermakna peningkatan jumlah leukosit jaringan vena pada pasien insufisiensi vena kronik dibandingkan normal (52,63 % vs 18,755) dengan nilai P 0,039. Analisa lebih lanjut dengan rasio odd, dimana pasien dengan peningkatan jumlah leukosit jaringan vena memiliki 4 kali lipat kemungkinan menderita insufisiensi vena kronik (Crude OR 4,81; CI 95% 1.02 - 22.57; P value 0.046), dan setelah dianalisa menggunakan variabel perancu usia, jenis kelamin, Diabetes mellitus, Hipertensi, Perokok, Dislipidemia, adjusted OR bertambah menjadi 6 kali lipat (Adjusted OR 6,66; CI 95% 1.16 - 38.31; P value 0.033) Kesimpulan. Terdapat hubungan antara nilai inflamasi lokal dengan parameter hitung jumlah lekosit jaringan vena dengan fungsi vena pada pasien insufisiensi vena kronik dengan parameter time refluks yang diperiksa dengan DUS.

ABSTRACT
Background: Venous function abnormality associated with inflammation and venous hypertension is the main pathophysiology of Chronic Venous Insufficiency (CVI). Proving the relationship between local inflammation factors in venous tissue and its function became an important point because the veins studied are used as a conduit for Coronary Artery Bypass Graft (CABG) procedure, and its patency evaluation will affect the mortality and morbidity rate in Coronary Artery Disease (CAD). Methods: This is a cross-sectional study, evaluating 35 Great Saphenous Veins (GSV) tissues taken as conduit for CABG procedure from CAD patients that have been previously examined using Duplex Ultrasound (DUS) for GSV reflux time from September-November 2014 at National Cardiac Centre Harapan Kita. Vein tissue samples were stained with Hematoxylin-Eosin and the vein tissue leucocyte count were evaluated by an independent anatomical pathologist. Reflux time and vein tissue leukocyte count results were then grouped into 2 categories each and analysed with chi-square test to assess the relationship between the two variables Result: There was significant difference of elevated leukocyte count evaluated in patients with CVI according to DUS reflux time (52,63%) compared to normal ones (18.75%) (p=0.039). The risk for patients with elevated total leukocyte count to develop CVI was 4 times greater than those who have normal count (crude OR 4.81; 95% CI 1.02 to 22.57; p=0.046) and after adjusted for confounding factors, such as age, sex, and history of diabetes, hypertension, smoking, and dyslipidaemia, the risk was increased into 6 times (adjusted OR 6.66; 95% CI 1.16 to 38.31; p=0.033). Conclusion: There is significant relationship between local inflammatory factors, evaluated using total leukocyte count, with venous functions, evaluated using DUS reflux time, in CVI patients.;Background: Venous function abnormality associated with inflammation and venous hypertension is the main pathophysiology of Chronic Venous Insufficiency (CVI).
