"Infark ventrikel kanan yang terutama terjadi sebagai komplikasi infark enitas penaykit tersendiri dimana dapat terjadi gangguan hemodinamik mayor."

"Infark ventrikel kanan yang terutama terjadi sebagai komplikasi infark inferior merupakan entitas penvakit tersendiri dimana dapat Jerjadi gangguan hemodinamik mayor, Pemeriksaan hemodinamik, elektrokardiografi (EKG), radionuklid angiografi dan ekokardio graft digunakan untuk mengetahui keterlibatan ventrikel kanan pada infark inferior. Infark ventrikel kanan terjadi pada 30 sampai 50% kasus infark inferior. Kami telah melakukan penelitian pada 37 pasien dengan infark inferior akut (dengan metode non invasif) dengan tujuan menilai peranan ekokardiogra.fi dalam diagnosis infark ventrikel kanan dan membandingkan aensitivitaxtiya terhadap EKG dan kriteria klinis. Pada ekokardiografi, 12 dari 37 pasien (32%) menunjukkan keterlibtitan ventrikel kanan. Tamla Kussmaul terjadi pada 27% pasien dan menunjukkan sensitivitas 50%, spesifisitas 88%, dan ketepatan prediksi 70%. Hantaran prekordial kanan pada EKG (V3R dan V4R) mendeteksi infark ventrikel kanan pada 30% pasien dengan sensitivitas, spesifisitas dan ketepatan prediksi masing-masing sebesar 67%, 88%, dan 73%. Gambaran ekokardiografi terdiri dari pembesaran ventrikel kanan dengan hipokinesia alau akinesia. Dilatasi dan disfungsi ventrikel kanan diperoleh dari besar relatif ventrikel kanan terhadap ventrikel kiri. Cara ini lebih sensitif dan spesifik dibandingkan gejala klinik dan EKG.

Right ventricular myocardial infarction (RVMl) predominantly a complication of inferior wall myocardial infarction i.v a distinct clinical entity in which major hemodynamic disturbance may occur. Bedside hemodynamic measurement, electrocardiographs, gated blood pool radionuclide angiography and echocardiography are used to identify right ventricular involvement in setting of inferior wall infarction. RVMl as assessed by various diagnostic methods accompanies 30 to 50% of inferior wall infarction. We studied 37 consecutive patients of acute inferior wall infarction (by non invasive method) to determine echocardiographic evidence of RVMl and compared its sensitivity to electrocardiography and clinical criteria. On echocardiography 12 out of 37 patients (32%) had right ventricular involvement. Kussmaul's signs was present in 27% of the patients and it had sensitivity of 50%, specificity of 88% and predictive accuracy of 70%. Right sided precordial leads (VjR ~ V4R) on elect rocardiography showed evidence of RVMl in 30% of patients with sensitivity, specificity and predictive accuracy of 67%, 88% and 73% respectively. Echocardiographic features included enlargement of right ventricle and hypokinesia or akinesia of right ventricular wall. Right ventricular dilatation and dysfunction is gained from relative right and left ventricular dimension on echocardiography. it is more .sensitive and specific than clinical signs and ECG.

AbstractMortality in patients with acute myocardial infarction (AMI) has decreased significantly and appears to be the result of current reperfusion therapeutic strategies. Reperfusion itself may develop into reperfusion injury. Therefore, management of these patients poses several challenges, such as diagnosing and managing heart failure, identifying persistent or inducible ischaemia, estimating the need for anticoagulation, and assessing overall cardiovascular risk. This case presentation will demonstrate the impact of cardiac magnetic resonance imaging (MRI) in the assessment of the pathophysiology of AMI inthe current reperfusion era. Cardiac MRI can provide a wide range of clinically useful information which will help clinicians to manage and choose specific therapeutic strategies for AMI patients."

"Evidence from epidemiologic studies suggests that periodontal diseases may exert a weak to moderate influence on the severity and course of coronary heart disease. The aim of this study was to investigate whether an association between chronic oral infections and the presence of an acute myocardial infarction (AMI) exists. A total of 248 patients after AMI and 249 healthy controls were recruited for this study. The oral assessment included caries frequency (DMFT indices), number of teeth, probing pocket depths, bleeding on probing, clinical attachment level, as well as radiographs to diagnose apical lesions. The medical examination included a blood analysis, e.g. the determination of the serum concentration of C-reactive protein (CRP). The data analysis showed statistically significant differences between AMI patients and the controls with regard to number of missing teeth (p = 0.001), DMFT index (p = 0.001) and presence of apical lesions of endodontic origin (p = 0.001). Logistic regression showed that the probability of having lesions of endodontic origin was with an odds ratio of 1.54 (95 % CI 1.10-2.16; p = 0.012) considerably higher in the AMI patient group. Likewise, the AMI patients had with an odds ratio of 1.21 (95 % CI 1.14-1.28; p < 0.001) a higher number of missing teeth. The data from the blood analysis, in particular the CRP values, showed no significant correlation with the number of apical lesions. The results of the present study underline that patients, who have experienced a myocardial infarction, had more missing teeth and a higher number of inflammatory processes, especially of endodontic origin, than healthy patients."

"Beberapa penelitian terdahulu menunjukkan kontradiksi hubungan antara dispersi QT dengan kejadian takiaritmia ventrikel dan atau kematian jantung mendadak. Penelitian-penelitian itu tidak mengeluarkan pengguna obat penghambat reseptor beta, bahkan pengguna obat tersebut merupakan mayoritas pada sampel mereka. Karena penggunaan penghambat reseptor beta sebagai pencegahan sekunder yang masih rendah di Pusat Jantung Nasional Harapan Kita, maka penelitian ini dilakukan untuk mengetahui hubungan antara dispersi QT dengan kejadian takiaritmia ventrikel dan atau kematian jantung mendadak pada pasien pascainfark. Interval QT, dispersi QT dan variabel klinis dibandingkan antara 36 orang pasien pascainfark yang mengalami takiaritmia ventrikel dan atau kematian jantung mendadak (kelompok kasus), dengan 75 pasien pascainfark yang tidak mengalami kedua kejadian tersebut (kelompok kelola). Dispersi QT yang lebih panjang (115 + 41 msec vs 81 + 25 msec, p < 0.001). Interval QT maksimal terkoreksi juga lebih panjang pada kelompok kasus (534 + 56 vs 501 + 35 msec, p < 0.001). Analisa regresi logistik menunjukkan adanya hubungan antara pemanjangan dispersi QT dengan kejadian takiaritmia ventrikel dan atau kematian jantung mendadak dengan RO 3,2, 4, dan 5,8 masing-masing untuk nilai potong 80, 90, dan 100 mdet. Dispersi QT dapat memprediksi kejadian takiaritmia ventrikel dan atau kematian jantung mendadak pada pasien infark miokard akut. Hasil ini menunjukkan bahwa dispersi QT tetap bermanfaat pada kondisi bebas pengaruh obat penghambat reseptor beta. (Med J Indones 2005; 14: 230-6)

Recent studies showed contradictive results of the relation between QT dispersion and the occurrence of ventricular tachyarrhythmias and/or sudden cardiac death. In addition, beta adrenoreceptors blocking agents, which are known to decrease the incidence of lethal arrhythmias after myocardial infarction, administered to the majority of patients in those studies population. Since b-blocker as secondary prevention drug was underutilized at National Cardiovascular Center Harapan Kita, this study was performed to find out the relation between QT dispersion and ventricular tachyarrhythmias and/or sudden cardiac death after previous myocardial infarction. The QT interval duration, QT dispersion and clinical variables of 36 postinfarction patients with history of sustained ventricular tachyarrhythmias and/or sudden cardiac death (event group) were compared with 75 postinfarction patients without such events (control group). QT dispersion differed significantly between study groups and was increased in the event group (115 ± 41 msec vs 81 ± 25 msec, p < 0.001). Corrected maximal QT interval duration was also prolonged in the event group (534±56 vs 501±35 msec, p < 0.001). Regression analysis showed that increasing QT dispersion was related to the occurrence of ventricular tachyarrhythmias and/or sudden cardiac death with OR of 3.2, 4, and 5.8 for cut-off point of 80, 90, and 100 msec respectively. The QT dispersion could predict the occurrence of ventricle tachyarrhythmias and/or sudden cardiac death in patient with AMI. This study confirmed that the QTd remain useful in free of beta blocking agents state. (Med J Indones 2005; 14: 230-6)"

"Latar Belakang: Pasien infark miokard akut (IMA) dengan hipertensi memiliki risiko yang lebih tinggi untuk terjadinya major adverse cardiac events (MACE). Pengukuran left ventricular mass index (LVMI) dengan ekokardiografi dapat membantu mengidentifikasi pasien IMA dengan hipertensi yang memiliki risiko untuk terjadinya MACE. Namun, penelitian mengenai hubungan antara LVMI dengan kejadian MACE pada pasien IMA dengan hipertensi pasca revaskularisasi perkutan belum ada di Indonesia.Tujuan: Mengetahui hubungan antara LVMI dan MACE pada pasien IMA dengan hipertensi pasca revaskularisasi perkutan.Metode: Penelitian ini merupakan studi kohort retrospektif di RSUPN Dr. Cipto Mangunkusumo dengan menggunakan data rekam medis pada periode tahun 2018–2022. Nilai LVMI didapatkan berdasarkan pemeriksaan ekokardiografi. Kejadian MACE dinilai pada saat perawatan Intensive Cardiology Care Unit (ICCU). Analisis menggunakan uji univariat, bivariat (chi-square), dan multivariat (regresi logistik) untuk melihat hubungan antara LVMI dan MACE pada pasien IMA dengan hipertensi pasca revaskularisasi perkutan.Hasil: Dari 160 pasien dengan IMA dan hipertensi yang menjalani revaskularisasi perkutan, terdapat 38 subjek (23,8%) yang mengalami MACE selama perawatan di ICCU. Dari 51,9% subjek dengan nilai LVMI meningkat, terdapat 34,9% yang mengalami MACE. Terdapat hubungan yang bermakna antara LVMI dan MACE dengan RR 2,99 (IK 95% 1,51-5,90) p 0,002). Pada analisis multivariat regresi logisitk, setelah memperhitungkan variabel perancu (usia dan penyakit ginjak kronik), LVMI secara independen terkait dengan peningkatan risiko kejadian MACE, dengan adjusted RR yang disesuaikan sebesar 2,869 (IK 95% 1,443–5,703) p 0,003.Kesimpulan: Terdapat hubungan yang bermakna antara LVMI dan MACE pada pasien IMA dengan hipertensi pasca revaskularisasi perkutan.

Background: Patients with acute myocardial infarction (AMI) and hypertension have a higher risk of major adverse cardiac events (MACE) complications. Measuring the left ventricular mass index (LVMI) with echocardiography can help to identify AMI patients with hypertension who are at risk for MACE. However, study regarding the association between LVMI and MACE occurrence in patient with AMI and hypertension post-percutaneous coronary intervention (PCI) has not been conducted in Indonesia.

Objective: To determine the association between LVMI and MACE in patients with AMI and hypertension after PCI.

Methods: This is a retrospective cohort study at Dr. Cipto Mangunkusumo National General Hospital utilizing medical record data from the period of 2018 to 2022. The LVMI values were obtained based on echocardiographic examinations. MACE events were assessed during ICCU (Intensive Cardiology Care Unit) admission. The analysis utilized univariate, bivariate (chi-square), and multivariate (logistic regression) tests to examine the association between LVMI and MACE in patients with AMI and hypertension post-PCI.

Results: A total of 160 patients with AMI and hypertension undergoing PCI, 38 subjects (23.8%) experienced MACE during follow up in ICCU. Among 51,9% subjects with increased LVMI, 34.9% experienced MACE. There was a significant association between LVMI and MACE with a relative risk (RR) of 2,99 (95% CI 1,51–5,90, p 0,002). After adjustment for the confounders (age and chronic kidney disease) in a multivariate analysis logistic regression, LVMI was independently associated with risk for MACE with adjusted RR 2,869 (95% CI 1,443–5,703, p 0,003)

Conclusion: There was a significant association between LVMI and MACE in patients with AMI and hypertension who have undergone percutaneous revascularization."

Background: This study was carried out to identity occupational status as a risk factor associated with myocardial infarction among male workers who hospitalized at National Cardiovascular Center Harapan Kita.

Methods: Case-control study with myocardial infarction as cases (n = 77) and controls (n = 77) were selected and matched on age. lnfomtation about occupation and classical risk factors for myocardial infarction was obtained with questionnaire and through subjects? medical record. The relation between myocardial infarction and occupational status was evaluated by logistic regression analysis, adjusting for a number of selected risk factors.

Results: After adjusting for obesity, hypertension, family history, educational group, marital status, and working hour, we found that, compared to manual unskilled occupational status, higher occupational status increased risk of myocardial infarction with OR 4,17 (95% CI 0,98 - 17,73), OR 6,67 (95% C1 1,56 - 28,52), OR 11,11 (95% CI 2,94 - 41,95), and OR 14,17 (95% Cl 3,24 - 61,99) respectively for manual skilled, non manual low level, non manual middle level, and non manual high level occupational status.

Conclusions: Differences in myocardial infarction risk among occupational status were found. Non manual high level occupational status were at highest risk. Differences in psychosocial factors in developing countries may contribute to observed results."

"Turbulensi laju jantung (heart rate turbulence [HRT]) baru-baru ini dianggap sebagai prediktor terbaru paling kuat untuk terjadinya kematian mendadak (sudden cardiac death [SCD]) melebihi prediktor lain yang telah ada sebelumnya. Pasien penyakit jantung koroner yang menjalani reperfusi koroner ternyata memberikan hasil HRT lebih baik dan hal ini mencerminkan pulihnya respon baroreseptor.Penelitian ini akan membandingkan nilai turbulence onset (TO) dan turbulence slope(TS) pada dua jenis reperfusi (PCI dan fibrinolitik) Subjek menjalani monitoring EKG selama 24 jam setelah dilakukan revaskularisasi. TO ditentukan dengan cara mengukur perubahan relatif dua interval RR irama sinus setelah ekstrasistol ventrikel dan dua RR interval terakhir sebelum ekstrasistol ventrikel. TS dihitung dengan dengan mengukur slope maksimum yang dibuat tiap 5 buah RR interval. Terdapat 13 pasien (usia rata-rata 56 + 9 tahun) yang memenuhi syarat untuk ikut dalam penelitian. Sepuluh pasien menjalani fibrinolitik dan tiga pasien menjalani PCI. Terdapat perbedaan bermakna nilai TO antara kelompok PCI dan fibrinolitik (-3,3 + 1,7 % vs -0,2 + 0,9 %; P=0,03). Terdapat kecenderungan kelompok PCI memberikan nilai TS yang lebih baik dibanding kelompok fibrinolitik, walaupun secara statistik tidak signifikan ( 7,7 + 4,4 msec/RR interval vs 3,4 + 2,6 msec/RR interval; P = 0,056). Disimpulkan bahwa subjek dengan STEMI akut yang menjalani PCI mempunyai nilai TO yang lebih baik dibanding subjek yang menjalani terapi fibrinolitik.

Heart rate turbulence (HRT) as novel predictor of sudden cardiac death were superior to all other presently available indicators. HRT significantly was improves after successful reperfusion reflecting rapid restoration of baroreceptor response. We investigated turbulence onset (TO) and turbulence slope (TS) values among patients with acute ST-elevation myocardial infarction (STEMI) underwent revascularization by means of primary PCI or fibrinolytic. We hypothesized that the values of TO and TS were different in two kinds of revascularization treatment. The subjects underwent 24 hours ECG recording after revascularization therapy. TO was quantified by the relative change of the first two sinus RR intervals following a ventricular premature beat (VPB) and the last two sinus RR intervals before the VPB. TS was quantified by the maximum positive slope of a regression line assessed over any sequence of five subsequent sinus rhythm RR intervals within the first two sinus rhythm intervals after a VPB. Thirteen patients (mean of age 56 + 9 years old) who underwent revascularization treatment of acute STEMI were eligible as subject of this study.Ten patients underwent fibrinolytic therapy and three patients underwent primary PCI. TO value was significantly different between PCI group and fibrinolytic group (-3.3 + 1.7 % vs -0.2 + 0.9 % ; P=0.03). The Primary PCI group has better outcome on turbulence slope value (TS) than fibrinolytic group but not significance (7.7 + 4.4 msec/RR interval vs 3.4 + 2.6 msec/RR interval; P = 0.056). In conclusion, TO was better in acute STEMI patient undergone PCI compare to that undergone fibrinolytic therapy."

"Intervensi koroner perkutan primer (IKPP) merupakan pilihan utama terapi repefusi pada infark miokard akut dengan elevasi segmen ST (IMAEST) dan obstruksi mikrovaskular (OMV) merupakan salah satu komplikasi yang sering terjadi pada IKPP. Osteoprotegerin (OPG) merupakan tumor necrosis factor receptor yang konsentrasinya meningkat pada pasien IMA-EST. Studi yang menganalisis hubungan konsentrasi serum OPG dengan luasnya infark masih sangat terbatas. Metode. Tiga puluh enam pasien yang menjalani intervensi koroner perkutan primer (IKPP) pada bulan September hingga November 2013, direkrut secara konsekutif pada studi potong lintang ini. Dilakukan analisis hubungan antara konsentrasi serum OPG sebelum IKPP dengan hs-trop T 24 jam pasca IKPP. Hasil. Analisis bivariat menunjukkan hubungan antara konsentrasi serum OPG dengan hs-trop T (r = 0.41, p =0.015). Analisis multivariat konsentrasi serum OPG dan onset nyeri mempengaruhi luas infark (indeks kepercayaan 5.15 – 49.19, p =0.017 dan indeks kepercayaan 2.56 - 15.28, p = 0.005). Kesimpulan. Hasil penelitian ini menunjukkan hubungan antara konsentrasi serum osteoprotegerin saat masuk dengan luas infark miokard yang diukur dengan hs-trop T pada pasien IMA-EST yang menjalani IKPP.

Primary percutaneous coronary intervention (PPCI ) is the preferred option for reperfusion therapy in acute ST-elevation myocardial infarction (STEMI) patients and microvascular obstruction (MVO) is one of the complication that might occurred during PPCI. Osteoprotegerin (OPG) is a tumor necrosis factor receptors that may increased in STEMI patients. Studies that analyze the relationship between serum concentrations of OPG with the extent of infarction are still very limited.

Method. Thirty six patients underwent PPCI were enrolled in this cross sectional study during September to November 2013. We analyzed the relationship between serum concentrations of OPG before PPCI with the level of hs-trop T measured 24 hours after PPCI.

Results. Bivariate analysis showed a significant correlation between serum osteoprotegerin concentration and hs-trop T (r=0.41, p=0.015). Multivariate analysis showed significant correlation between the extent of infarction with both onset of pain (confidence interval 2.56-15.28, p=0.005) and serum osteoprotegerin concentrations (confidence interval 5.15-49.19, p= 0.017).

Conclusion. This study showed that serum osteoprotegerin concentration have a significant relationship to the extent of infarction measured with hs-trop T in acute STEMI patients underwent PPCI."
