"[ABSTRAKLatar 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 rematikHasil : 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.

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.

"Latar belakang: Stenosis mitral SM akibat penyakit jantung reumatik PJR memiliki disfungsi sistolik ventrikel kiri VK secara subklinis bila menggunakan parameter global longitudinal strain GLS walaupun rata-rata pasien memiliki fraksi ejeksi FE baik. Pada PJR, inflamasi kronis menyebabkan terjadinya nekrosis fibrinoid, pada akhirnya menjadi fibrosis miokard. Berdasarkan teori ini, fibrosis miokard merupakan salah satu dasar teori yang mendasari disfungsi sistolik VK pada SM. Namun hingga kini penelitian yang menilai hubungan ini belum ditemukan.Tujuan: Mengetahui hubungan GLS sebagai parameter fungsi sistolik dengan volume fibrosis VK pada SM akibat PJR.Metode: Studi potong lintang melibatkan pasien SM akibat PJR akan menjalani pemeriksaan MRI jantung untuk mengevaluasi fibrosis miokard dengan metode LGE dan ekokardiografi untuk menilai GLS. Kedua data diolah menggunakan analisa korelasi.Hasil: Terdapat 36 pasien subjek penelitian. Volume fibrosis miokard rata-rata VK 4,9 2,7 . Walaupun FE baik median 62 , nilai GLS menurun dibandingkan nilai rujukan normal 13,5 3,9 . GLS memiliki korelasi sedang dengan volume fibrosis VK r = -0,432; p 0,009 . Tidak ada korelasi antara GLS dengan area katup mitral maupun gradien tekanan transmitral rata-rata. Tidak didapatkan juga korelasi antara FE dengan volume fibrosis.Kesimpulan: GLS memiliki korelasi sedang dengan volume fibrosis VK pada pasien SM akibat PJR.

Abstract Background. The correlation between the extent of myocardial fibrosis and subclinical LV systolic dysfunction in rheumatic mitral stenosis MS has not been widely studied. We sought to evaluate the correlation between the extent of LV myocardial fibrosis quantified by Late Gadolinium Enhancement LGE CMR and Global Longitudinal Strain GLS by Speckle Tracking Echocardiography STE in these patients.Methods. We prospectively evaluated 36 consecutive rheumatic MS patients who were planing to undergo intervention in our center. Then we evaluate the correlation between the extent of LV myocardial fibrosis quantified by Late Gadolinium Enhancement LGE CMR and Global Longitudinal Strain GLS by Speckle Tracking Echocardiography STE Results. Thirty six patients showed mean of LGE was 4,9 2,7 . Despite good ejection fraction median 59.5 , IQR 28 68 , the LV GLS was reduced mean 13.5 3.9 compared to normal reference value. There was moderate correlation between GLS and LGE r 0,432 p 0,009 . There are no correlations between GLS with mitral valve area MVA and mean mitral valve gradient mean MVG . No significant correlation was found between ejection fraction and LGE.Conclusion. There was moderate correlation between LGE and GLS in patients with rheumatic MS.

"Latar belakang. Timbulnya stasis darah dan pembesaran atrium kiri menyebabkan peningkatan angka kejadian trombus di atrium kiri dan apendiks atrium kiri (Left Atrial Appendage-LAA) pada SM. Diameter atrium kiri yang membesar disebutkan sebagai faktor terjadinya pembentukan LASEC dan meningkatkan angka kejadian tromboemboli. Selain itu adanya stasis darah yang dibuktikan dengan penurunan ejeksi fraksi LAA dan kecepatan aliran darah LAA dapat mencetuskan timbulnya trombus. Perubahan moluker adhesi sICAM-1 dan sVCAM-1 berhubungan dengan kejadian tromboemboli. Tetapi apakah terdapat hubungan antara peran hemodinamik, terutama terhadap diameter, fraksi ejeksi dan kecepatan aliran darah pada LAA dengan kadar molekul adhesi seperti sICAM-1 dan sVCAM-1 belum terjawab. Metode. Pasien SM derajat sedang-berat (tanpa adanya regurgitasi mitral signifikan) yang menjalani pemeriksan ekokardiografi transesofageal diikutsertakan secara konsekutif sejak Januari-April 2014. Penilaian fungsi apendiks atrium kiri dilakukan dengan pemeriksaan transesofageal ekokardiografi. Kadar sICAM-1 dan sVCAM-1 dari vena perifer diukur dengan teknik enzyme-linked immunosorbent assay. Hasil. Sebanyak 26 subyek penelitian dengan rerata usia 38,92±11,93 tahun, 65,3% berjenis kelamin perempuan, dan 46,1% memiliki irama fibrilasi atrium. Dengan sampel tersebut, didapatkan tidak ada hubungan antara komponen fungsi apendiks atrium kiri, baik diameter, ejeksi fraksi, dan kecepatan aliran darah LAA dengan kadar sICAM-1. Tidak terdapat hubungan antara fungsi LAA pada variabel diameter dengan kadar sVCAM-1. Terdapat hubungan terbalik antara ejeksi fraksi LAA dengan kadar sVCAM-1 (-0,21, p=0.038, 95%KI -0,41- -0,01) dan hubungan terbalik antara kecepatan aliran darah LAA dengan kadar sVCAM-1 (-0,29, p=0,048, 95%KI -0,59- -0,003). Kesimpulan. Semakin rendah ejeksi fraksi dan kecepatan aliran darah LAA maka semakin tinggi kadar sVCAM-1.

Background: Blood stasis and left atrial enlargement increase the incidence of thrombus in the left atrium and left atrial appendage (LAA). Enlargement of left atrial diameter is a factor for LASEC formation and increase the incidence of thromboembolism. Blood stasis which evidenced by a decrease in ejection fraction and LAA blood flow velocity can trigger the presence of thrombus. Changes in soluble adhesion molecules sICAM-1 and sVCAM-1 associated with thromboembolic events. But relationship between the role of hemodynamics, especially the ejection fraction and blood flow velocity in the LAA with the levels of adhesion molecules such as sICAM-1 and sVCAM-1 is not well understood.

Methods: Patient with moderate-severe Mitral Stenosis (in the absence of significant mitral regurgitation) underwent transesophageal echocardiography from January to April 2014. Levels of sICAM-1 and sVCAM-1 from peripheral vein were measured by enzyme-linked immunosorbent technique assay.

Results: A total of 26 subjects with a mean age of 38.92 ± 11.93 years, 65.3% female, and 46.1% had atrial fibrillation. We found no association between components of left atrial appendage function: diameter, ejection fraction and blood flow velocity of LAA with sICAM-1 levels. There was no relationship between the LAA function in the variable diameter of LAA with sVCAM-1 levels. There is an inverse relationship between ejection fraction of LAA and levels of sVCAM-1 (-0.21, p = 0.038, 95% KI -0,41- -0,01) and an inverse association between LAA blood flow velocity and levels of sVCAM-1 (-0 , 29, p = 0.048, 95% KI -0.59 - 0.003).

Conclusion: Low ejection fraction of LAA is associated with higher the levels of sVCAM-1. Low LAA blood flow velocity is associated with higher the levels of sVCAM-1."
