"Lima puluh persen penderita gagal jantung merupakan gagal jantung dengan fraksi ejeksi yang normal (HFPEF). Morbiditas dan mortalitas HFPEF belumlah jelas. Latihan olahraga telah menjadi rekomendasi pertama dalam beberapa panduan klinis, namun belum pada HFPEF. Strain longitudinal apikal 4 ruangan dapat digunakan sebagai nilai prognostik. Perbaikan fungsi longitudinal intrinsik ventrikel kiri menggunakan strain longitudinal apikal empat ruangan akibat latihan olahraga belumlah diketahui. Kuasi eksperimental menggunakan 30 sampel konsekutif HFPEF, dilakukan program latihan olahraga tersupervisi. Program latihan olahraga dilakukan selama satu bulan. Dilakukan pemeriksaan ekokardiografi, 6MWT, kuesioner MLWHF dan WHO. Terdapat perbedaan yang signifikan dalam 6MWT, nilai skoring MLWHF dan WHO5 sebelum dan sesudah latihan olahraga. Didapatkan nilai strain longitudinal sebesar -16,20% (-10,7% sampai dengan -17,81%). Strain longitudinal apikal 4 ruangan mengalami perbaikan pada minggu ke 2 dan ke 4 latihan olahraga (sebelum latihan olahraga LS = -16,20 [-10,70 to -17,81]; minggu ke dua latihan olah raga LS = -18,00±2,69 dan minggu ke 4 latihan olahraga LS = -21,86±1,79) dan terdapat perbedaan yang signifikan (p < 0,001).

Fifty percent of patients with heart failure are heart failure with preserved ejection fraction (HFPEF). Morbidity and mortality of HFPEF is unclear. Exercise has become the first recommendation in several clinical guidelines, but not yet in HFPEF. Apical 4 chamber longitudinal strain can be used as a prognostic value. But the improvement of longitudinal intrinsic left ventricular function using apical 4 chamber longitudinal strain due to exercise training is not yet known. Quasi- experimental study using thirty consecutive sample of HFPEF. Exercise training program was conducted for a month. Echocardiography, 6MWT, MLWHF and WHO questionnaire was performed before and after exercise. There was significant differences in the 6MWT, the value of MLWHF and WHO5 score before and after exercise. Longitudinal strain values obtained by -16.20 % (-10.7% to -17.81%). Four chamber longitudinal strain was improved at weeks 2 and 4 of exercise (before exercise LS = -16.20[-10.70 to -17.81]; the second week of exercise training LS = -18.00±2,69 and week 4 exercise LS = -21.86 ± 1.79) and there were significant differences (p < 0.001). There was an improvement in the longitudinal intrinsic left ventricular function before and after exercise training in patients with heart failure with preserved ejection fraction."

ABSTRACTBackground. In MS right ventikel (RV) dysfunction and pulmonary hypertension often occur as complication. There is no research that connects the pulmonary vascular resistance before surgery with RV function and its changes in the case of rheumatic mitral stenosis who underwent mitral valve surgery.Methods. This study is a prospective cohort study which involves 31 patients with rheumatic mitral stenosis who underwent surgery at National Cardiovaskular Center Harapan Kita Hospital from April 2014 to March 2015. Patients underwent echocardiography before surgery, after surgery pre-hospital discharge and mid-term follow-up at clinic. Statistical analysis was performed to see the relationship between preoperative pulmonary vascular resistance (PVR) with RV function at mid term follow up, which is assessed using echocardiographic parameters right ventricular longitudinal speckle strain, and also with right ventricle longitudinal speckle strain postoperative changes (delta strain).Results. There is no correlation between pre operative PVR with RV longitudinal speckle strain at mid term follow-up (r 0,199 p 0,264), and post operative changes or delta strain (r 0.174 p 0.350).Conclusion. RVP before surgery is not associated with right ventricle longitudinal speckle strain at follow up mid term and post operative changes or delta strain., Background. Acute rheumatic fever and rheumatic heart disease is still regarded as animportant public health problem especially in developing countries. Mitral stenosis (MS) is asequale of rheumatic fever which are most commonly found. In MS right ventikel (RV)dysfunction and pulmonary hypertension often occur as complication. The right ventricle hasa smaller muscle mass so it is more sensitive to changes in pressure loads. There is noresearch that connects the pulmonary vaskular resistance before surgery with RV functionand also changes in the case of rheumatic mitral stenosis who underwent mitral valvesurgery.Methods. This study is a prospective cohort study which involves 31 patients with rheumaticmitral stenosis who underwent surgery at National Cardiovaskular Center Harapan Kita Hospital from April 2014 to March 2015. Patients underwent echocardiography before surgery, after surgery pre-hospital discharge and mid-term follow-up at clinic. Statisticalanalysis was performed to see changes in RV function with longitudinal speckle strain, aftersurgery pre-hospital discharge and mid-term follow-up at clinic. Analysis also performed tosee the relationship between preoperative pulmonary vascular resistance (PVR) with RVfunction at mid term follow up, which is assessed using echocardiographic parameters rightventricular longitudinal speckle strain, and also with right ventricle longitudinal specklestrain postoperative changes (delta strain). Results. Right ventricular function after surgery seen with longitudinal speckle strainimproved from -12.94 ± 3.63 preoperatively into -13.06 ± 3.63 after surgery pre hospitaldischarge, and -15.25 ± 3.75 at follow-up evaluation (p 0.007). There is no correlationbetween pre operative PVR with longitudinal speckle strain at mid term follow-up (r 0,199 p0,264), and RV longitudinal speckle strain post operative changes or delta strain (r 0.174 p0.350). Conclusion. After mitral valve surgery, right ventricle longitudinal speckle strain improves.RVP before surgery is not associated with right ventricle longitudinal speckle strain at follow up mid term and right ventricle longitudinal speckle strain post operative changes or deltastrain. ]"

ABSTRACTBackground. Worsening renal function (WRF) is associated with worse outcomes among patients who are hospitalized with acute decompensated heart failure (ADHF). Clinical characteristics at admission may help identify patients at increased risk of WRF. The aim of this study was to create in admission scoring system to simplify identification patients at risk of WRF in ADHF setting.Methods. A retrospective data of 614 patients admitted with ADHF was analyzed. By the definition WRF occurred when serum Creatinin increased at anytime during hospitalization by ≥ 0.3 mg/dL or by ≥ 25% from admission.Results. Worsening renal function developed in near 26% patients. The independent predictors of WRF analyzed with backward selection logistic regression were: age > 75 years old (p < 0.0001), female (p = 0.034); history of hypertension (p = 0.001); anemia (p = 0.005); and in admission serum Creatinin (p = 0.013). A scoring system was generated from this final model. An internal validation with bootstrap method showed good optimism (0.01088808).Conclusion.

"[ABSTRAKLatar Belakang : Endotelial glikokaliks merupakan bagian penting dalam barrier vaskular. Keadaan inflamasi, hiperglikemia, iskemia, dan hipervolemia dapat menyebabkan kerusakan glikokaliks. Kerusakan glikokaliks menyebabkan cairan terekstravasasi ke interstisial. Pada pasien pasca BPAK terjadi peningkatan syndecan-1 dalam plasma yang merupakan penanda terjadinya kerusakan endotelial glikokaliks. Hipervolemia pasca BPAK juga dapat memperburuk kerusakan glikokaliks dan hipervolemia sendiri berhubungan dengan kejadian komplikasi mayor pasca operasi. Pemilihan jenis cairan yang tepat diperlukan pada kondisi ini.Tujuan : Mengetahui apakah terdapat perbedaan efek pemberian koloid dan kristaloid terhadap endotelial glikokaliks pada pasien pasca bedah pintas arteri koroner.Metode Penelitian : Penelitian ini merupakan studi intervensi acak pada pasien pasca BPAK dengan pengambilan sampel secara konsekutif. Pasien yang tidak responsif terhadap pemberiaan cairan, memiliki fungsi pompa jantung pre oparasi yang turun, memiliki kelainan fungsi ginjal, atau menggunakan IABP saat operasi akan dieksklusi dari penelitian. Responsivitas terhadap cairan dinilai dengan pemeriksaan Doppler karotis. Pasien kemudian akan diberikan cairan koloid atau kristaloid secara acak. Sampel darah diambil pre dan pasca pemberian cairan. Kadar syndecan-1 diperiksa dengan metode ELISA.Hasil : Subyek penelitian sebanyak 54 orang dengan 27 orang mendapat cairan koloid dan 27 orang mendapat cairan kristaloid. Hasil pemeriksaan syndecan-1 pre pemberian cairan adalah 1,97 (0,29-14,03) ng/ml pada kelompok yang mendapat Gelofusine dan 2,14 (0,68-11,80) ng/ml pada kelompok Ringer?s lactate (p = 0,736). Syndecan-1 pasca pemberian cairan adalah 1,78 (0,23-10,98) ng/ml pada kelompok Gelofusine dan 2,08 (0,72-12,23) ng/ml pada kelompok Ringer?s lactate (p=0,276). Selisih antara syndecan-1 pre dan pasca pemberian cairan adalah 0,23 (-1,3 - 3,55) ng/ml pada kelompok Gelofusine dan 0,14 (-2,12 - 1,80) ng/ml pada kelompok Ringer?s lactate (p = 0,043). Syndecan-1 turun pada 23 pasien (85,5%) kelompok Gelofusine dan 15 pasien (55,6%) kelompok Ringer?s lactate (p = 0,017). Analisis bivariat pada beberapa faktor yang diduga mempengaruhi perubahan syndecan-1 menunjukkan bahwa jenis cairan merupakan satu-satunya faktor yang berpengaruh.Kesimpulan : Penelitian ini membuktikan bahwa terdapat perbedaan efek antara pemberian koloid (Gelofusine) dan kristaloid (Ringer?s lactate) terhadap endotelial glikokaliks pada pasien pasca BPAK. Pemberian koloid dapat lebih memperbaiki kerusakan endotelial glikokaliks yang terjadi pasca BPAK.

ABSTRACTBackground : Endothelial glycocalyx is an important part of vascular barrier. Inflammation, hyperglycemia, ischemia, and hypervolemia contribute to shedding of the glycocalyx. Damage to the glycocalyx can make fluid extravasation to interstitial. Increasing syndecan-1 value in plasma as marker of shedding the endothelial glycocalyx can occured in the post CABG patients. Hypervolemia is a worsening factor of the shedding in glycocalyx and hypervolemia contribute to major complication after operation. It is important to choose the appropriate fluid for this patient.Objective : The aim of this study is to examine the difference effect of colloid and crystalloid administration on endothelial glycocalyx in post CABG patients.Methods : This is a randomized trial which recruits post CABG patients cosecutively. Non fluid responsive, reduced left ventricle ejection fraction, reduced renal function, or used of IABP during operation are excluded. Fluid responsiveness will be measured by carotis Doppler. Patients then given colloid or crytalloid randomly. Blood sample were taken before and after fluid loading. Syndecan-1 value examined using ELISA method.Result : The total of 54 subjects with 27 patients received colloid and 27 patients received crystalloid. Syndecan-1 pre loading are 1,97 (0,29-14,03) ng/ml in Gelofusine group vs 2,14 (0,68-11,80) ng/ml in Ringer?s lactate group (p = 0,736). Syndecan-1 post loading are 1,78 (0,23-10,98) ng/ml in Gelofusine group vs 2,08 (0,72-12,23) ng/ml in Ringer?s lactate group (p=0,276). The difference of syndecan-1 value in pre and post fluid loading are 0,23 (-1,3 - 3,55) ng/ml in Gelofusine group and 0,14 (-2,12 - 1,80) ng/ml in Ringer?s lactate group (p = 0,043). Lowering syndecan-1 occured in 23 patients (85,2%) in Gelofusine group and 15 (55,6%) in Ringer?s lactate group (p= 0,017). Bivariat analysis showed that kind of fluid is the only factor can influence the difference of syndecan-1.

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.
