Non-arteritic anterior ischemic optic neuropathy (NAION) adalah penyakit multifaktorial yang mekanismenya belum diketahui secara pasti, namun hiperkoagulasi diduga merupakan faktor yang berperan pada NAION. Karena merupakan penyakit mikrovaskular, maka aktivasi koagulasi pada fase awal dapat menyebabkan koagulasi pada NAION. Penelitian ini bertujuan untuk mengetahui peran hiperkoagulasi pada kejadian NAION dalam upaya memberikan tata laksana yang lebih baik pada pasien NAION. Penelitian dilakukan pada bulan Oktober 2020 hingga April 2022 di Poliklinik Mata Divisi Neuro-oftalmologi FKUI-RSCM Kirana. Subjek adalah pasien NAION yang dibagi menjadi kelompok hiperkoagulasi dan non-hiperkoagulasi. Penelitian potong lintang dilakukan untuk menilai penanda koagulasi dini yaitu E-selectin, P-selectin, microparticle tissue factor (MPTF), prothrombin fragment 1+2 (PF1+2), dan hasil pemeriksaan penunjang berupa optical coherence tomography (OCT), OCT angiography (OCTA), dan Humphrey visual field (HVF). Uji klinis eksperimental dilakukan untuk menilai efektivitas terapi hiperkoagulasi dalam waktu 1 bulan. Terdapat 64,3% subjek NAION dengan hiperkoagulasi dan terjadi aktivasi penanda koagulasi dini pada kedua kelompok. Kesesuaian lokasi OCTA dengan ganglion cell inner plexiform layer (GCIPL) ditemukan pada 33% subjek, retinal nerve fiber layer (RNFL) pada 6,7% subjek, dan HVF pada 40% subjek, namun tidak terdapat korelasi jumlah sektor atau kuadran yang terkena. Nilai GCIPL dan HVF tidak berkorelasi dengan OCTA, di kuadran yang terkena, RNFL berkorelasi dengan OCTA. Kelompok terapi hiperkoagulasi menunjukkan penurunan perfusi lebih sedikit. Tajam penglihatan membaik pada 57,2% subjek di kelompok NAION dengan hiperkoagulasi dan 42,9% di kelompok NAION nonhiperkoagulasi. Berdasarkan fungsi lapang pandang, kedua kelompok menunjukkan perbaikan pada sebagian besar subjek (71,4% pada kelompok NAION dengan hiperkoagulasi dan 85,8% pada kelompok NAION nonhiperkoagulasi). Disimpulkan hiperkoagulasi berperan pada mekanisme NAION, sehingga tata laksana terkait hiperkoagulasi penting pada pasien NAION dalam mencapai luaran klinis yang lebih baik. ......Non-arteritic anterior ischemic optic neuropathy (NAION) is a multifactorial disease with an uncertain mechanism. Hypercoagulability is believed to be one of the factors involved in NAION. Considering that NAION is a microvascular disease, this study assumes that coagulation activation in the early phase is sufficient to cause a coagulation state in NAION. The aim of this research is to evaluate the role of hypercoagulability in the occurrence of NAION in order to provide better management for NAION patients. The subjects were NAION patients divided into hypercoagulability and non-hypercoagulability groups. A cross-sectional study was conducted to assess early coagulation markers, namely E-selectin, P-selectin, microparticle tissue factor (MPTF), and prothrombin fragment 1+2 (PF1+2), as well as ancillary tests such as optical coherence tomography (OCT), OCT angiography (OCTA), and Humphrey visual field (HVF). An experimental clinical trial was conducted to evaluate the effectiveness of hypercoagulation therapy within one month. It was found that 64.3% of NAION subjects had hypercoagulability. Early coagulation marker activation occurred in both groups. There was a concordance between OCTA and ganglion cell inner plexiform layer (GCIPL) location in 33% of subjects, retinal nerve fiber layer (RNFL) in 6.7% of subjects, and HVF in 40% of subjects. However, no correlation was found regarding the number of affected sectors or quadrants. GCIPL and HVF values did not correlate with OCTA, whereas in the affected quadrant, RNFL correlated with OCTA. The hypercoagulation therapy group showed less perfusion reduction. Visual acuity improved in 57.2% of subjects in the hypercoagulability NAION group and 42.9% in the non-hypercoagulability NAION group. Based on visual field function, both groups showed improvement in the majority of subjects (71.4% in the hypercoagulability NAION group and 85.8% in the non- hypercoagulability NAION group). It can be concluded that hypercoagulability plays a role in the mechanism of NAION, thus emphasizing the importance of managing hypercoagulability in NAION patients to achieve better clinical outcomes.

Latar Belakang. Stenosis Mitral (SM) tinggi prevalensinya di negara berkembang karena erat terkait dengan prevalensi penyakit jantung demam rematik (PJR). Pasien SM sedang-berat terdapat peningkatan regio turbulensi dan shear stress mengakibatkan kerusakan endotel pembuluh darah sehingga meningkatkan resiko tromboemboli. P-selectin merupakan molekul adhesi berperan dalam proses inflamasi dan sebagai faktor protrombotik yang diekspresikan secara cepat. Indeks volume atrium kiri (IVAK) merupakan parameter superior untuk mengukur fungsi atrium kiri dengan ekokardiografi. Metode. Penelitian potong lintang melibatkan 20 pasien SM sedang-berat dengan MVA <1.5 cm2 yang menjalani Komisuratomi Mitral Transvena Perkutan (KMTP) yang diambil secara konsekutif pada bulan Mei 2013 sampai Oktober 2013 di Pusat Jantung Nasional Harapan Kita Jakarta. Pasien diambil sampel darah pra dan pasca KMTP untuk diperiksa kadar P-Selectin. Kemudian hasilnya dianalisa secara statistik. Hasil. Dalam studi ini, tidak didapatkan asosiasi antara IVAK dengan ekspresi kadar P-selectin pra dan pasca KMTP. Hal ini ditunjukkan dengan nilai pra KMTP β= -0.103 (95% CI -0.251,0.045) p=0.16 dan pasca KMTP β= 0.009 (95% CI -0.155,0.172) p=0.91. Setelah dilakukan regresi linier dengan penyesuaian (adjusted) terhadap variabel perancu yakni usia, jenis kelamin, dan atrial fibrilasi tetap tidak didapatkan asosiasi antara IVAK dengan kadar P-selectin dengan nilai pra KMTP β= -0.154 (95% CI -0.340,0.032) p=0.09 dan pasca KMTP β= -0.049 (95% CI -0.250,0.152) p=0.61. Kesimpulan. Tidak ada perbedaan nilai P-selectin pra dan pasca KMTP. Nilai IVAK yang sudah jelek tidak berhubungan dengan kadar P-selectin pra dan pasca KMTP pada pasien SM.

ABSTRACT
Background. The prevalence of Mitral stenosis (MS) remains significant in developing countries related to prevalence of Rheumatic Heart Disease (RHD).In moderate-severe MS patients enormous increase in turbulent region and shear stress causing dysfunction of vascular endothelial, as consequence it increase the risk of thromboembolic complication. Pselectin is an adhesion molecule that play role in inflammation process, it express rapidly in minutes. Left Atrial Volume Index (LAVI) is superior parameter compare with other echocardiography two dimension method to assess left atrial function. Methods. Study was designed as cross-sectional study involving 20 MS moderate-severe patients with MVA< 1.5 cm2 who performed successful Percutaneous transvenous Balloon Mitral Valvulotomy (PBMV). Samples were taken consecutively from May 2013 to October 2013 at the National Cardiovascular Center Harapan Kita Jakarta. Blood samples of Pselectin were collected pre and post PBMV. The result was statistically analyzed by using echocardiography data of LAVI prior PBMV to describe any association between expression of P-selectin and atrial function. Result. In our study, we found no association between LAVI and expression of P-selectin level pre and post PBMV MS patient. This data describe in each of value of pre PBMV β= - 0.103 (95% CI -0.251,0.045) p=0.16 and post PBMV β= 0.009 (95% CI -0.155,0.172) p=0.91 After we performed linear regression with adjusted confounding variable including sex, age, and atrial fibrillation, still we found no association between LAVI and P-selectin level. This data describe in each of value of pre PBMV β= -0.154 (95% CI -0.340,0.032) p=0.09 and post PBMV β= -0.049 (95% CI -0.250,0.152) p=0.61. Conclusion. We found there is no difference in P-selectin level pre and post PBMV. There is no association between poor LAVI value and expression of P-selectin pre and post PBMV in MS.

Latar belakang : Stenosis mitral (SM) masih merupakan masalah kesehatan yang penting di Indonesia. Pada SM terjadi peningkatan kadar P selectin karena disfungsi endotel dan aktivasi platelet. Komisurotomi mitral transvena perkutan (KMTP) merupakan tatalaksana baku untuk penderita SM yang dapat memperbaiki kemampuan aktivitas fisik yang pada akhirnya akan mempengaruhi kadar P selectin. Belum ada penelitian yang menghubungkan antara tingkat aktifitas fisik dengan kadar P Selectin 3 bulan pasca KMTP pada SM rematik. Metode : Penelitian ini merupakan penelitian potong lintang. Dari 56 subyek penelitian yang menjalani KMTP sejak bulan Mei 2013 sampai Februari 2014 di Rumah Sakit Jantung dan Pembuluh Darah Harapan Kita, didapatkan 35 sampel yang memenuhi kriteria penerimaan . Data klinis dan data ekokardiografi sebelum dan 3 bulan pasca KMTP diambil dari catatan medis. Dilakukan wawancara 3 bulan pasca KMTP. Tingkat aktivitas fisik dibagi menjadi 2 kelompok: kelompok 1 1-4 METs, kelompok 2 > 4 METs. Kadar P selectin diambil 3 bulan pasca KMTP. Selanjutnya dilakukan analisa statistik untuk mengetahui hubungan antara tingkat aktivitas fisik dengan kadar P Selectin 3 bulan pasca KMTP pada SM rematik Hasil : Pasien yang akan menjalani KMTP memiliki rerata usia 40,00±11,58 tahun dengan proporsi perempuan lebih tinggi daripada laki-laki (74,3%) dan dengan proporsi irama sinus yang lebih tinggi daripada irama atrial (57,1%). Dari uji T didapatkan ada perbedaan bermakna rata-rata kadar P selectin 3 bulan pasca KMTP pada tingkat aktivitas fisik 1-4 METs dan > 4 METs, dimana rerata kadar P selectin 3 bulan pasca KMTP pada tingkat aktivitas fisik > 4 METs lebih rendah secara bermakna dibandingkan 1-4 METs (p=0,003). Setelah dilakukan analisa multivariat terlihat tingkat aktivitas fisik pasca KMTP tetap berpengaruh terhadap kadar P Selectin 3 bulan pasca KMTP (p=0,001). Area Katup Mitral (AKM) pasca KMTP berpengaruh terhadap kadar P selectin 3 bulan pasca KMTP (p=0,018), namun tingkat aktivitas fisik pasca KMTP lebih besar pengaruhnya dibandingkan AKM. Kesimpulan : Terdapat hubungan antara tingkat aktivitas fisik dengan kadar P selectin 3 bulan pasca KMTP dimana pada tingkat aktivitas yang lebih tinggi ( > 4 METs) kadar P selectin lebih rendah 10,489 ug/ml dibandingkan tingkatan aktivitas fisik 1-4 METs.

ABSTRACT
Background: 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.
