"ABSTRAKLatar Belakang: Insulin receptor substrate-1 IRS-1 merupakan protein adaptor yang berada di sitoplasma dan memiliki peran penting dalam insulin signaling pathway. Adanya perubahan informasi genetik berupa polimorfisme pada gen IRS-1 diduga kuat berkontribusi terhadap kejadian resistensi insulin akibat terganggunya kaskade insulin signaling di sejumlah jaringan. Gangguan kaskade insulin signaling di pembuluh darah, terutama yang melibatkan PI3K menyebabkan penurunan sintesis NO yang selanjutnya akan berdampak terhadap kejadian disfungsi endotel. Polimorfisme gen IRS-1 berupa varian Gly972Arg menjadi predisposisi genetik terhadap kejadian disfungsi endotel dan penyakit kardiovaskuler.Tujuan: Penelitian ini bertujuan untuk mengetahui hubungan antara polimorfisme gen IRS-1 berupa varian Gly972Arg dengan kejadian disfungsi endotel yang dinilai dengan flow mediated dilation FMD .Metode: Suatu studi potong lintang dengan subjek penelitian adalah karyawan RSJPDHK yang telah menjalani penelitian IRS-1 di Divisi Litbang RSJPDHK. Didapatkan besar subjek penelitian adalah 81 orang. Data primer adalah hasil pemeriksaan FMD, sedangkan data sekunder diambil dari rekam medis. Genotyping IRS-1 rs1801278 diperiksa menggunakan alat Real Time PCR Applied Biosystem tipe ABI 7500 menggunakan metode Taq Man Assay dan pemeriksaan FMD dengan alat Aloka Prosound yang dilakukan di Divisi Vaskuler RSJPDHK.Hasil: Terdapat 81 subjek yang diikutsertakan dalam penelitian ini. Subjek dibagi dalam 3 kelompok, yakni grup wildtype/CC 14 orang , heterozigot/CT 52 orang , dan homozigot mutan/TT 15 orang . Terdapat hubungan yang bermakna antara polimorfisme gen IRS-1 berupa varian Gly972Arg dengan disfungsi endotel p= 0,019 . Setelah dilakukan penyesuaian terhadap merokok, hipertensi, diabetes melitus dan sindroma metabolik terdapat kecenderungan meningkatnya risiko disfungsi endotel berdasarkan pola polimorfisme OR 12,8; IK 95 1,5-106; p 0,018 pada grup CT dan OR 18; IK 95 1,8-183,3; p 0,015 pada grup TT .Kesimpulan: Terdapat hubungan yang bermakna antara polimorfisme gen IRS-1 berupa varian Gly972Arg dengan disfungsi endotel yang dinilai menggunakan FMD.

ABSTRACT<>br>Background Insulin receptor substrate 1 functions as one of the key downstream signaling molecules in the insulin receptor signaling pathways. Insulin has multiple physiological effects on the vascular tissues including regulation of the expression of endothelial nitric oxide synthase eNOS . This regulatory effect of insulin on endothelial function is mediated via the activation of the signaling pathway involving the insulin receptor insulin receptor substrate 1 IRS 1 phosphoinositide 3 kinase PI3K . Thus genetic changes in IRS 1 may potentially contribute toward the development of insulin resistance. Gly972Arg IRS 1 variant may contribute to the genetic predisposition to develop endothelial dysfunction and cardiovascular disease. However, little is known about the interaction between Gly972Arg IRS 1 variant and endothelial dysfunction in vivo.Objective To investigate the genetic polymorphism and its relationship with endothelial dysfunction measured by flow mediated dilation FMD .Methods 81 subjects were genotyped for the Gly972Arg IRS 1 polymorphism using Taq Man method. FMD was performed using Aloka Prosound at the Vascular clinic.Results 81 subjects were clustered into three groups CC 17,3 , CT 64,2 and TT 18,5 . There was a significant relationship between Gly972Arg IRS 1 variant and endothelial dysfunction measured by FMD p 0,019 . After adjustment of smoking status, hypertension, diabetes mellitus and metabolic syndrome, there was an increased risk between Gly972Arg IRS 1 variant with endothelial dysfunction OR 12,8 95 CI 1,5 to 106 p 0,018 in CT group and OR 18 95 CI 1,8 to 183,3 p 0,015 in TT group .Conclusion Gly972Arg IRS 1 variant may be a significant genetic determinant for endothelial dysfunction measured by FMD."

"Intervensi Koroner Perkutan Primer (IKPP) merupakan pilihan utama untuk mengembalikan aliran darah dan perfusi pasien yang mengalami Infark Miokard Akut dengan Elevasi Segmen ST (IMA-EST). Tapi tidak selalu mengembalikan aliran yang cukup pada tingkat mikrosirkulasi, hal ini disebabkan oleh obstruksi mikrovaskular (OMV). Banyak penelitian telah membuktikan pengaruh inflamasi terhadap kejadian OMV, tingginya rasio neutrofil limfosit pasca IKPP menggambarkan respon inflamasi. Tujuan penelitian ini adalah untuk menilai hubungan rasio neutrofil limfosit (RNL) terhadap kejadian obstruksi mikrovaskular yang dinilai dengan pemeriksaan myocardial blush kuantitatif (QuBE). Metode: Sebanyak 33 subjek IMA–EST yang menjalani IKPP dipilih secara konsekutif sejak 1 September 2013 sampai 30 Oktober 2013. RNL diambil saat masuk UGD, penilaian myocardial blush (MB) diambil segera pasca IKPP, angiografi untuk RCA (RAO 30˚) dan LCA (LAO 60˚-90˚). Kemudian RNL dikirim ke laboratorium untuk diperiksa dengan dengan Sysmex 2000i, blush dinilai dengan program komputer QuBE. Perhitungan statistik dinilai dengan SPSS 17. Hasil: Dari 33 pasien didapatkan proporsi terbanyak berjenis kelamin laki-laki sebesar 75,7%, rerata usia pasien 56±9.8 tahun. Analisa statistik menunjukkan tidak terdapat hubungan antara RNL dan QuBE (β=-0,180;p=0,664) namun terdapat kecenderungan setiap kenaikan 1 unit RNL akan menurunkan QuBE sebesar 0,180 unit arbiter. Setelah dilakukan adjusted terhadap faktor perancu didapatkan kecenderungan penurunan yang lebih besar meskipun tetap tidak menunjukkan hubungan yang bermakna. (koef β=-0,331 ; p=0,527).

Primary percutaneus coronary intervention (PPCI) is a first of choice to return patient’s blood flow and perfusion with ST elevation myocardial infarction (STEMI). However, it is not always sufficiently reflow of microcirculation due to Microvascular Obstruction (MVO). Many studies had proved that neutrophil to lymphocyte ratio (NLR) has emerged as a potent composite inflammatory marker. The aim of this study is to evaluate association between NLR and MVO by Quantitative Blush Evaluator (QuBE).

Methode: 33 STEMI patients undergoing primary PCI were consecutivly recruited from September to October 2013. The NLR was withdraw at patient admission. We evaluate the myocardial blush immediately after PCI done. Angiography views were RAO 30˚ for RCA, and LAO 60˚-90˚for LCA. Then the NLR was sent to laboratory for examination. QuBE was done to evaluate myocardial blush. Statistical analysis was done by SPSS 17.

Results: From thirty three patients included in the study, there were 75,75% men, with mean age 56±9.8 years old. Statistical analysis showed no correlation between NLR and QuBE (β=-0,180;p=0,664) but there was decrease of 0,180 unit arbiter QuBE for each 1 unit of peripheral NLR. After adjustment of confounding factor, there was more decreasing value although there is no significant correlation. (coef β=-0,331;p=0,527)."

ABSTRACTBackground: Mitral stenosis (MS) is an important health problem in Indonesia. P selectin level in MS increases due to endothelial dysfunction and platelet activation. Percutaneous transvenous mitral commissurotomy (PTMC) is one of the management for MS patients. Thus, the physical activity can improve and in turn affect the level of P selectin. There has been no study link the level of physical activity with the level of P Selectin 3 months after of PTMC.Method: This is a cross sectional study with 56 subjects who underwent PTMC from May 2013 to February 2014 at the Hospital of National Heart Centre Harapan Kita. Then, 35 samples met the inclusion criteria. Clinical and echocardiography data before and 3 months after PTMC were taken from medical records. Interviews were conducted 3 months after PTMC. Physical activity levels were divided into 2 groups: group 1 (1-4 METs) and group 2 (> 4 METs). Sample for P selectin was taken 3 months after PTMC. Further statistical analysis was done to determine the relationship between physical activity level with level of P Selectin 3 months after PTMC in rheumatic MS.Result: Patients who will undergo PTMC have the mean age of 40.00 ± 11.58 years with a higher proportion of women than men (74.3%) and the proportion of sinus rhythm is higher than atrial rhythm (57.1%) . T-test analysis result showed significant difference in the average levels of P selectin 3 months after PTMC on the level of physical activity 1-4 METs and > 4 METs. The average P selectin levels on the level of physical activity in group with > 4 METs was significantly lower compared with group 1-4 METs (p = 0.003). After multivariate analysis, the physical activity level still has an effect on the P selectin levels 3 months after PTMC (p = 0.001). The Mitral Valve Area (MVA) after PTMC also has an effect on P selectin levels (p = 0.018). However, the level of physical activity after PTMC has a greater effect than MVA.Conclusion: There is a relationship between the level of physical activity with P selectin levels 3 months after PTMC.Group with higher activity level (> 4 METs) have lower level of P selectin (with the mean difference levels of P Selectin 10,489 ug/ml);Background: Mitral stenosis (MS) is an important health problem in Indonesia.

ABSTRACTBackground : Arterial stiffness is related to higher risk of cardiovascular events. Blood pressure variability using ambulatory blood pressure monitoring has proven as a cardiovascular prognosis predictor and also serves as predictor of arterial stiffness. The study aims to prove the correlation between blood pressure variability measurement using home blood pressure monitoring and arterial stiffness measurement using pulse wave velocityMethods : A cross-sectional study was conducted to 57 subjects with native hypertension between 30-50 years old. Subjects underwent PWV measurement and was monitored for their blood pressure using HBPM for three consecutive days (morning and night BP each repeated two times). Subjects also screened for related confoundings i.e., diabetes, obesity, dyslipidemia, renal function disturbance. Results : As many as 21% subjects is obese, 8.7% had diabetes melitus, 60% had dyslipidemia, 14% is smoker. There is no subjects with renal function disturbance. There is no correlation between obesity, dyslipidemia, smoking habit, and sex to arterial stiffness, whereas diabetes melitus has a strong correlation to arterial stiffness (p=0,01). There was a significant difference between sytolic blood pressure measurement at each group of blood pressure based on day and time, but no difference found between diastolic blood pressure. There is significant correlation between arterial stiffness and mean diastolic pressure, mean morning diastolic pressure, variance coefficient of diastolic pressure, variance coefficient of morning blood pressure.Conclusion : We conclude that HBPM is reliable in measuring blood pressure variability. There is no significant relation of systolic blood pressure variability to arterial stiffness, but there is a tendency of positive correlation.

Background In patients undergoing mitral valve surgery, right ventricular function may decline immediately after the surgical procedure. This condition may sometimes remain, but may also improve later on. Many factors have been proposed to account for this phenomenon. As of yet, there are no studies using multivariate analysis to investigate factors that may be predictors of right ventricular function improvement after mitral surgery.

Objective This study aims to identify factors that may be predictors of right ventricular function improvement in patients with right ventricular dysfunction following mitral valve surgery.

Methods This is a retrospective cohort study, taking place at National Cardiovascular Center Harapan Kita NCCHK , Jakarta, Indonesia. Subjects are patients who underwent mitral valve surgery between January 2016 until February 2017. Data taken include basic characteristics, surgical data, drugs prescribed after surgery, and echocardiography data before surgery, predischarge, and six months after surgery.

Results There are 100 subjects who fulfilled the criteria to participate in this study. There are 68 68 cases of right ventricular function improvement and 32 32 cases without improvement. The median of predischarge TAPSE increases significantly six months after surgery, from 1,1 0,6 1,5 to 1,4 0,7 2,8 with p value."

Dan penurunan rekatifitas platelet kelompok clopidogrel menurun mendekati nilai yang diharapkan hingga jam 8.Kesimpulan : Reaktifitas platelet ticagrelor lebih rendah dibandingkan clopidogrel saat jam pertama pasca loading obat. Terdapat 45% (5 pasien) pada kelompok clopidogrel yang tetap memiliki reaktifitas platelet tinggi pada pemeriksaan jam pertama, keempat dan kedelapan, serta 9% (1 pasien) pada ticagrelor yang memiliki kenaikan nilai reaktifitas platelet pada jam keempat dan kedelapan

Objectives : This study sought to compare platelet reactivity by180 mg ticagrelor and 600 mg clopidogrel in primary PCI STEMI patients.

Background: The ability of ticagrelor in inhibiting platelet functions was more potent than clopidogrel in stable CAD and UAP/NonSTEMI patients. According to the PLATO trial or PLATO-platelet substudy, patients treated with 180 mg ticagrelor had better clinical endpoint and more platelet inhibition compared to 300 mg clopidogrel. The study we conducted was to see the platelet reactivity at 1st, 4th, and 8th hour after ingestion of 180 mg ticagrelor compared

to 300 mg clopidogrel in STEMI patients Methods: This is a randomized double blind clinical trial carried out in Department of Cardiology and Vascular Medicine Universitas Indonesia/ National Cardiovascular Center Harapan Kita in April - June 2013. As many as 22 clopidogrel or ticagrelor nave STEMI

patients undergoing primary PCI with were recruited. Platelet reactivity (PRU) was assessed by

Multiplate at 1,4,8 h after LD.

Result : Both nave ticagrelor and clopidogrel goups had 11 patients each. About 45% patients

in clopidogrel group have high reactivity platelet at 1h, 4h and 8 h MEA analysis, and 9%

patients in ticagrelor group have high reactivity platelet at 4h and 8 h MEA analysis.

Conclusion: The action of Ticagrelor in platelet reactivity was lower compared to Clopidogrel in

STEMI patients. 45 % patients in clopidogrel group maintained high platelet reactivity at 1st, 4th

and 8th hour after LD, while 9% patients in ticagrelor group had high platelet reactivity started at

4th up 8th hour after LD."

"Latar Belakang. Fibrilasi atrium (AF) adalah komplikasi aritmia yang paling sering ditemukan pada pasien yang menjalani operasi bedah pintas arteri koroner (BPAK) dengan insidens yang bervariasi antara 20-50%. Walaupun diketahui sebagai gangguan yang bersifat sementara, namun AF pasca operasi dapat mengancam jiwa serta dikaitkan juga dengan peningkatan angka kesakitan dan kematian yang bermakna, sehingga perlu diketahui faktor-faktor yang dapat menjadi prediktor terhadap kejadian AF pasca BPAK. Penelitian ini menilai interval elektromekanikal atrium yang diukur dengan menggunakan ekokardiografi Doppler jaringan dan dispersi interval elektromekanikal sebagai prediktor kejadian AF pasca BPAK. Metode. Seratus delapan pasien diambil secara konsekutif untuk studi potong lintang ini, mulai bulan Mei hingga September 2012 dari pasien penyakit jantung koroner yang menjalani operasi BPAK di Pusat Jantung Nasional Harapan Kita, Jakarta. Pasien menjalani pemeriksaan ekokardiografi sebelum operasi BPAK. Dilakukan penilaian terhadap interval elektromekanikal dengan Doppler jaringan pada lateral atrium kiri serta dispersi interval interatrial. Pasien dimonitor selama perawatan terhadap kejadian AF.Hasil. Dalam studi kami, 27 dari 108 (25%) pasien mengalami AF pasca operasi BPAK. Dari analisa terlihat perbedaan interval elektromekanikal di atrium kiri sebesar 18.04 ms dan terdapat perbedaan dispersi interval interatrial 10.25 ms antara kelompok pasien yang mengalami AF pasca BPAK dan yang tidak mengalami AF. Dari hasil analisa didapatkan nilai titik potong interval elektromekanikal di lateral atrium kiri sebesar 77,75 ms dan dispersi interval elektromekanikal sebesar 38,95 ms sebagai prediktor terhadap kejadian AF pasca BPAK.Kesimpulan. Interval elektromekanikal pada lateral atrium kiri dan dispersi interval interatrial dengan menggunakan Doppler jaringan merupakan potensial prediktor terhadap kejadian AF pasca BPAK.

Background. Atrial fibrillation (AF) is the most common arrhythmia complication in patient undergone coronary artery bypass grafting (CABG) with the incidence of 20- 50% according to different studies. Although this complication is temporary but can be life threathening, and increased the number of mortality and morbidity. Thus, it is very important to identified factors that can predict the occurance of AF post CABG. This study use atrial electromechanical interval and interval dispertion measured by tissue Doppler echocardiography as predictor of AF post CABG.

Methods. One hundred and eight patients were included in this cross sectional study. Samples were taken consecutively from May to September 2012 among patients with coronary artery disease undergoing CABG at the National Cardiovascular Center Harapan Kita Jakarta. The patients underwent a preoperative transthoracic echocardiography with tissue Doppler evaluation. We measured the atrial electromechanical interval in the lateral of left atrium and interatrial interval dispertion. Patients was monitored thorugh out hospitalization for the occurance of AF.

Result. In our study, 27 out of 108 (25%) patients developed AF post CABG. There are 18.04 ms electromechanical interval difference in the lateral of left atrium and 10.25 ms interatrial dispersion difference between patients who suffer from post operative AF and non AF. From this study we have 77,75 ms as the cutoff point for interval electromechanical in the left atrium and 38.95 ms as the cutoff point for dispersion of interatrial interval as the predictor for AF post CABG.

Conclusion. The interval of Electromechanical in the lateral left atrium and interatrial interval dispersion using tissue dopper echocardiography are potensial predictor the occurrence of AF post CABG."
