Background: The clinical implications of precordial ST segment depression (PSTD) during acute inferior myocardial infarction has been an area of debate, and still under investigation with conflicting results. Based on previous studies, the presence of PSTD defines a high risk subset of patients with acute inferior myocardial infarction due to a more extensive myocardial ischemia that lead to a higher incidence of major adverse cardiovascular events (MACE). Despite of these results, others still considered this ECG finding as a benign electrical phenomenon. The aim of this study is to compare the incidence of in-hospital MACE in patients of acute inferior myocardial infarction with or without PSTD and to know whether PSTD can be used as a predictor of in-hospital MACE in acute inferior myocardial infarction.Methods: A total of 96 acute inferior myocardial infarction patients admitted from December 2013-2015 at Cardiology Department of Haji Adam Malik General Hospital were retrospectively analyzed. Patients were divided into two groups based on the presence of PSTD on admission ECG. Bivariate and multivariate analyses were performed to study the association between PSTD and in-hospital MACE, p value<0.05 was considered statistically significant.Results: The bivariate analysis showed that in-hospital MACE was significantly higher in patients of acute inferior myocardial infarction with PSTD than without PSTD (92% vs 8%, p<0.001). On multiple logistic regression analysis, patients of acute inferior myocardial infarction with PSTD have a 5.4 fold increased risk of in-hospital MACE than patients without PSTD (OR 5.480; 95% CI 1.759-17.067, p=0.003).Conclusion: The presence of precordial ST segment depression on admission ECG in acute inferior myocardial infarction patients was associated with a higher in-hospital MACE and was an independent predictor of in-hospital MACE.

Background: Determining the severity of mitral stenosis is important for both prognostic and therapeutic reasons. TTE is the gold standard method for assessment of severity mitral stenosis by using planimetry and pressure half time (PHT). Planimetry is accurate but highly operator dependent. PHT is affected by changes in preload or left ventricular compliance. In this study, we evaluate the posterior to anterior mitral valve leaflets length ratio as a novel simple parameter that can be used in peripheral by using common ultrasound to assess the severity of MS.Methods: This cross-sectional study involved 75 patients with rheumatic mitral stenosis (MS) who evaluate echocardiography in Adam Malik Hospital . The severity of MS was classified by planimetry and PHT. The posterior to anterior mitral valve leaflets length ratio was obtained by dividing posterior mitral valve leaflet length to anterior mitral valve leaflets length in the parasternal long axis views at the end diastole.Results: Severe (61.3%), moderate (32%), mild (6.7 %) MS. There was a strong correlation with the posterior to anterior mitral valve leaflets length ratio and mitral valve area by planimetry in spearman correlation ( r=0.892, p<0.001). ROC analysis of the posterior to anterior mitral valve leaflets length ratio with cut-off point < 0.68 could predict severe MS with sensitivity of 97%, specificity of 93%, positive predictive value of 96%, LR (+) of 13.85. Intra-observer and intra-observer variability of this parameter was good (Kappa value of 0.760–0.765) and significant (p< 0.001). Goodness of fit test with Hosmer-Lemeshow test showed this parameter fit with the data.Conclusion: The posterior to anterior mitral valve leaflets length ratio<0.68 can be used as a simple parameter in determining the severity of mitral stenosis with high sensitivity and specificity.

Background: Previously conducted researches showed that presence of SEC in the left atrium can constitute a risk factor for thrombus formation. Some previous studies have also reported that in addition to atrial fibrillation and blood stasis in the left atrium, the pathophysiology of left atrial thrombus and SEC occurring in patients with rheumatic mitral stenosis exhibits some other mechanisms, such as autoimmunity, inflammation and increased thrombotic activity. Methods: Cross sectional study was conducted between July 2015 to July 2017 in patient who admitted to Haji Adam Malik Hospital due to rheumatic mitral stenosis. They were divided into two groups according to presence of left atrial SEC. Result: From 104 patients, 52 (mean age 40 Â± 11 years; 71,2% women) were in the left atrial SEC-negative group and 52 patients (mean age 40 Â± 10 years; 73,1% women) were in the left atrial SEC-positive group. There were no significant differences in the leucocyte, 8,06Â±1,54 were in the left atrial SEC-negative group and 7,37Â±1,76 were in the left atrial SEC-positive group. In multivariate analysis, atrial fibrillation (OR = 51,311, 95% CI 3,723 â€“ 707,100, p = 0,003) neutrophil/lymphocyte ratio (OR = 21,641, 95% CI 5,174 â€“ 90,528, p < 0,001), mitral valve area (OR = 14,423, 95% CI 1,665 â€“ 124,908, p = 0,015), and RDW (OR = 5,743, 95% CI 1,349 â€“ 24,445, p = 0,018), These study show that neutrophil/lymphocyte ratio with cut off point of >3,2 had sensitivity, spesificity, positive predictive value, and negative predictive value to predict left atrial SEC is the same 81%, respectively. Conclusion: Atrial fibrillation, neutrophil/lymphocyte ratio, RDW and mitral valve area can predict left atrial spontaneous echocardiographic contrast in rheumatic mitral stenosis patients. Abstrak Latar Belakang: Penelitian sebelumnya menunjukkan adanya SEC di atrium kiri menjadi faktor risiko untuk pembentukan trombus. Pada pasien stenosis mitral rematik, risiko trombosis dan perkembangan SEC di atrium kiri tinggi. Beberapa penelitian sebelumnya melaporkan bahwa patofisiologi trombus dan SEC di atrium kiri selain fibrilasi atrium dan stasis aliran darah di atrium kiri juga adanya beberapa mekanisme lain seperti respon imun, inflamasi dan peningkatan aktifitas trombotik. Metode: Ini adalah penelitian observasional yang bersifat cross sectional, dilakukan dari Juli 2015 sampai Juli 2017 terhadap pasien stenosis mitral rematik yang datang ke rumah sakit Haji Adam Malik. Pasien dibagi 2 kelompok berdasarkan kehadiran SEC di atrium kiri menurut hasil pemeriksaan ekokardiografi. Hasil: Didapatkan 104 pasien, dimana 52 pasien (usia rata-rata 40 Â± 11 tahun, 71% wanita) merupakan kelompok tanpa SEC, dan 52 pasien (usia rata-rata 40 Â± 10 tahun, 73% wanita) merupakan kelompok dengan SEC. Tidak ada perbedaan bermakna pada lekosit, dimana kelompok tanpa SEC (8,06Â±1,54) dan kelompok dengan SEC (7,37Â±1,76). Dari analisis multivariat regresi logistik, didapatkan fibrilasi atrium (OR = 51,311, nilai IK 95% antara 3,723 â€“ 707,100, p = 0,003) rasio netrofil/limfosit (OR = 21,641, nilai IK 95% antara 5,174 â€“ 90,528, nilai p < 0,001), area katup mitral (OR = 14,423, nilai IK 95% antara 1,665 â€“ 124,908, nilai p = 0,015), dan RDW (OR = 5,743, nilai IK 95% antara 1,349 â€“ 24,445, nilai p = 0,018), merupakan prediktor independen untuk terjadinya SEC. Titik potong untuk nilai rasio N/L > 3,2 memiliki angka sensitivitas, sensitifitas, nilai prediktif positif dan nilai prediktif negatif yang sama yaitu masing-masing 81% untuk memprediksi kejadian SEC di atrium kiri pada pasien stenosis mitral rematik. Kesimpulan: Fibrilasi atrium, rasio netrofil/limfosit, RDW dan area katup mitral dapat menjadi prediktor SEC di atrium kiri pada pasien stenosis mitral rematik.

The aim of this study is to design a simple, bedside clinical prognostic scoring model and validate its ability to predict hospital mortality for patients with AHF. Methods: 255 patients with AHF were enrolled, divided into dead (n=121) and surÂvival (n=134) cohorts. The data were collected from January 2015 to September 2016.Data were collected restropectively. Multivariable analysis was applied to determine independent risk factors and develop the scoring system. Results: The Multivariate logistic regression analysis, hospital mortality was employed as dependent variable, while age umur (p=0.014,OR 4.314 CI 95%(1.346-13.822)), Diastolic Blood Pressure (p= 0.001 OR 6.213 CI 95%(2.1210-18.205 )), Systolic Blood Pressure ( p=0.002 OR 5.043 CI 95%( 1.854-13.717)), Heart Rate ( p=0.002 OR 3.933 CI 95%(1.658-9.332)), haemoglobin ( p = 0.044 OR 2.530 CI95%(1.026-6.242)), arrhytmia ( p=0.001 OR 7.658 CI 95%(2.217-26.457)), creatinine on admission ( p=0.002 OR 4.385 CI 95% (1.731-11.104)), QRS duration (p=0.00 OR 7.684, CI 95% (3.063-19.279)), as independent variables.According to each OR of these variables, we set the new scoring system of hospital mortality for AHF with good calibration by Hosner-lemeshow test ( p =1) and discrimination by AUC 0.925 (p<0.01 CI 95 % 0.891-0.959). The optimal cutt off for prediction mortality was total 6 points, sensitivity 81% and specificity 89%. We divided the patients with AHF as low risk whom total score 0-3 points (mortality in hospital 0-2%), moderate risk whom total score 4-5 points (mortality in hospital 13-46%), and 6-12 point as high risk. In the validation cohort indicated that SMASH score as new scoring system was effective with bootstrapping. Conclusion : The SMASH Score is a new scoring system of hospital mortality for AHF can predict with good performance in terms of discrimination, calibration and internally validation.

Background: Global Longitudinal Strain (GLS) is a sensitive measurement and has been studied as a parameter to assess myocardial deformity and had a prognostic value in STEMI patient, but this measurement is usually taken at echocardiography laboratory with software installed only, a simple parameter of systolic function that had been known is EPSS, the aim of this study is to determine the prognostic value of this simple parameter as a surrogate marker of myocardial deformity for mayor adverse cardiac event (MACE). Methods: This is an analytic observational study using ambispective cohort study, basic and echocardiographic data were collected from 66 adult subjects of acute STEMI from July 2016 until April 2017. Each subjects were followed-up for MACE (mortality, heart failure, ventricular arrhytmia and cardiogenic shock) 30 days since admission. Cut off point were taken from ROC curve. Statistical analysis test were used to examine the association between two variables and obtained odds ratio (OR) for EPSS. To obtain the degree of relationship between EPSS and GLS we were using corelation test with the value of p<0.05 was considered statistically significant. Result: In this study the optimum cut off value for EPSS was 7 mm with sensitivity and specificity of 72% and 71%, respectively. Bivariate analysis showed among EPSS >7 mm and GLS >-10,6% were associated with MACE in 30 days after STEMI. In multivariate analysis, GLS >-10,6% (OR 10,6 95%IK 2,5-44,7 p=0,001) and EPSS >7 mm (OR 5, 95%IK 1,12-22,56 p=0,035) remained significantly associated and had 83% probability for MACE in 30-days after STEMI. Using the corelation test we found that EPSS had a stronger relationship with GLS (r=0,795, p<0,001). Conclusion: Our data show that EPSS >7 mm had a strong relationship with myocardial deformity parameter and appears to be a strong predictor for MACE in 30-days after acute STEMI. Therefore, it can be taken earlier to help the cardiologist in emergency unit for futher appropriate management planning. Abstrak Latar Belakang: Global Longitudinal Strain (GLS) adalah parameter deformitas miokardium yang telah banyak diteliti untuk menilai fungsi sistolik ventrikel kiri serta kaitannya terhadap prognosis pasien IMA-EST, sayangnya pemeriksaannya cenderung terbatas dilakukan di laboratuÂrium ekokardiografi dengan alat ekokardiografi tertentu. Parameter fungsi sistolik lainnya yang cukup dikenal karena tekniknya yang sederhana dan dapat dilakukan di Unit Gawat Darurat adalah E-Point Septal Separation (EPSS), tujuan dari penelitian ini adalah melihat nilai prognosis EPSS sebagai indikator tidak langsung deformitas ventrikel kiri terdahap Kejadian Kardiovaskular Mayor (KKvM). Metode: Penelitian ini merupakan studi kohort ambispektif, 66 orang subjek IMAEST yang memenuhi kriteria inklusi dan eksklusi yang dirawat di Rumah Sakit Haji Adam Malik mulai Juli 2016 sampai April 2017 diambil data dasar dan ekokardiografinya, kemudian pasien diikuti selama 30 hari untuk KKvM (kematian, gagal jantung, aritmia ventrikel dan syok kardiogenik). Nilai titik potong EPSS diambil dari kurva ROC. Uji statistik dilakukan untuk menilai hubungan antara variabel untuk mendapatkan nilai rasio odds (RO) EPSS, uji korelasi digunakan untuk menilai kekuatan hubungan antara EPSS dengan GLS, p<0,05 dianggap bermakna. Hasil: Nilai titik potong EPSS yang didapatkan adalah 7 mm dengan sensitivitas 72%, spesifisitas 71%. Analisis bivariat menunjukkan nilai EPSS >7 mm dan GLS >-10,6% berhubungan dengan KKvM. Pada analisis multivariat, GLS >-10,6% (RO 10,6 95%IK 2,5-44,7 p=0,001) dan EPSS >7 mm (RO 5, 95%IK 1,12-22,56 p=0,035) secara signifikan tetap berhubungan dan memiliki probabilitas sebesar 83% dalam memprediksi KKvM 30 hari setelah IMAEST. Adapun nilai EPSS dan nilai GLS memiliki hubungan yang kuat (r=0,795, p<0,001). Kesimpulan: Data menunjukkan bahwa nilai EPSS >7 mm memiliki hubungan yang kuat dengan parameter deformitas ventrikel kiri dan suatu prediktor kuat pula terhadap KKvM dalam 30 hari setelah IMAEST. Hal ini menguntungkan kita sebagai klinisi karena dengan pemerÂiksaan EPSS yang sederhana ini dapat menjadi indikator adanya deformitas miokardium ventrikel kiri yang bernilai prognosis sehingga dapat dilakukan lebih dini untuk dapat menentukan strategi tatalaksana pada pasien IMAEST.

Precordial ST Segment Depression on Admission Electrocardiogram as a Simple Noninvasive Tool for Predicting Coronary Artery Disease Complexity in Patients with Inferior Myocardial Infarction Jaya Suganti, Anggia Chairuddin Lubis, Abdullah Afif Siregar, Andika Sitepu, Cut Aryfa Andra, Ali Nafiah Nasution, Harris Hasan Department of Cardiology and Vascular Medicine, Faculty of Medicine University of Sumatera Utara, Haji Adam Malik General Hospital, Medan, Indonesia Background: Whether a precordial ST segment depression (PSTD) is merely a benign electrical phenomena or a sign of multivessel coronary artery disease (MVCAD) in inferior myocardial infarction (MI) remains unclear. The objective of this study is to analyze the complexity of coronary artery disease (CAD) in inferior MI patients with PSTD and to investigate whether PSTD can be used as a predictor of MVCAD in inferior MI. Methods: Patients with inferior MI were divided into two groups based on the presence of PSTD on admission ECG and were compared based on the patientâ€™s coronary artery complexities. Results: A total of 215 patients with inferior MI were found in this study period, with 102 patients meet the inclusion and exclusion criteria. Patients with PSTD had a higher incidence of MVCAD and SYNTAX score. Further analyzes showed PSTD on admission ECG was an independent predictor of MVCAD in inferior MI [45 (66%) vs 23 (34%); OR 4.097; 95% CI 1.638-10.247; p=0.003). Conclusion: In daily clinical practice, PSTD on admission ECG may serve as a simple noninvasive tool for predicting MVCAD or a more complex CAD in inferior MI. Keywords: Precordial ST Segment depression, inferior myocardial infarction, SYNTAX score

Background: Confirming mitral valve area (MVA) by planimetry is one of the standard procedures for assessing mitral stenosis but MVA were frequently need to be confirmed by other echocardiography parameters that only available in sophisticated centers. Our aim was to evaluate the significance of a simple mitral inflow color M-mode velocity propagation (Vp) for estimating MVA and MS severity.Methods: The best color view of MS jet were taken from apical 4 chamber, the nyquist limit were adjusted for aliasing the central highest velocity, then M-mode were applied to MV to calculate Vp by measuring the slope of the blue jet with the first aliasing velocity. MVA,PHT and mean transmitral gradient were analyzed with Pearson correlation and linear regression. Predictive discrimination value of Vp were analyzed by ROC.Results: Thirty one MS patients had mean MVA planimetry 0.99 ± 0.35 cm2 and mean Vp 64.49 ± 21.63 cm/s. Vp that were found to have a strong negative correlation with MVA (Spearman rho -0.865, p < 0.01). Vp had a good predictive discrimination value as from AUC 0.931. Vp were found to have a moderate correlation with MVA by PHT ( Spearman rho -0.621, p <0.01). Vp more than 55 cm/s had 93.8% sensitivity and 86.7% specificity to distinguish severe MS.Conclusions: By making use of the high temporal resolution of M-mode, a simple color Mitral M-Mode Vp were found statistically significant for estimating MVA severity in MS. Interventional decision for MS could also consider Vp for its strong correlation with MVA on MS, especially for helping on targeting moderate to severe MS in rural and limited centers.

Background: Diastolic dysfunction as part of heart failure with preserved ejection fraction (HFpEF) has gain interests, due to the increasing prevalence rate and poor prognosis. Besides the mechanism is not fully understood, there are some difficulties in detecting the presence of diastolic dysfunction. Previous studies have shown correlation between some electrocardiographic parameters and diastolic function. Furthermore, the aim of this study is to assess the diagnostic value of the QTc interval in detecting left ventricular diastolic dysfunction.Methods: A cross sectional study was conducted on patients with clinical suspicion of heart failure. Electrocardiographic examination was performed to obtain QTc interval (msec) using the Bazett formula. Left ventricular diastolic function was assessed using Tissue Doppler Imaging by echocardiography. Using correlation test and ROC method, the relationships between QTc interval and LV diastolic function were investigated.Results: Of 82 patients analyzed, there were 62 patients (75.9%) known to have diastolic dysfunction. The QTc interval was found to be longer in the group with diastolic dysfunction compared to the normal group (442.9±27 vs. 402.1±18.2, p <0.001). There was a strong negative correlation between the QTc interval and diastolic function (r = -0.619; p <0.001). Using ROC analysis, the cut off point for QTc interval was 410 ms with 91% sensitivity, 70% specificity, and 90% positive predictive value.Conclusion: The QTc interval is an accurate, simple and highly feasible electrocardiographic parameter as a screening tool to determine the presence of left ventricular diastolic dysfunction.

Background: STEMI patients need revascularization to improve blood flow and myocardial reperfusion. Further information can be obtained from the ECG including infarct size and prognosis of STEMI patients. ST segment depression (STSD) in reciprocal leads isassociated with poorer prognosis. STEMI patients with STSD resolution have a better TIMI flow compared with no STSD resolution. The aim of this study was to look for TIMI flow for STEMI subjects who received fibrinolytic therapy with and without resolution of STSD shortly after fibrinolytic.Methods: This study is a prospective cohort study, in which 60 STEMI subjects, patients performed coronary angiography diagnostics to assess TIMI flow. The resolution on reciprocal STSD is defined as a decrease of 50% in the amount of reciprocal STSD in 90- minute after fibrinolytic therapy started.Results: Bivariate analysis showed that ejection fraction <40% with p = <0.001; QRS duration, p = <0.001; anterior STEMI with p = <0.001; are significant factors for STSD resolution. QRS Fragmentation with p = <0.001; STSD resolution with p = <0.001; ST elevation resolution with p = <0.001; are significant factors for TIMI Flow. In the TIMI Flow comparison with reciprocal STSD resolution; the resolution of reciprocal STSD has a better TIMI flow with OR 28 [(5.5-141.9), p = <0.001].Conclusion: There were differences in TIMI Flow in STEMI patients with reciprocal STSD resolution and without reciprocal STSD resolution who received fibrinolytic alteplase therapy, where STEMI patients with reciprocal STSD resolution had a better TIMI Flow compared with STEMI patients without reciprocal STSD resolution.
