We report three cases of acute myocardial infarction caused by left anterior descending (LAD) artery occlusion presenting as ST elevation in the inferior. Therefore, coronary angiography showed an occlusion of the LAD coronary artery. Our cases show the rare occurrence of left coronary circulation dominance affecting inferior leads. These cases show an unusual and very rare form of left dominance coronary circulation where LAD is wrapped around the apex and continuing as a posterior descending artery. This would make inferior myocardial infarction because of occluded LAD or determine as wrapped LAD.

We report an uncommon case of simultaneous cardio-cerebral infarction, due to Inferior – right ventricle ST Segment Elevation Myocardial Infarction (STEMI) with acute ischemic stroke. Incidence of cardio cerebral infarction is exceptionally rare, with an incidence rate as low as 0.009%. Hemodynamic compromise in patients with acute myocardial infarction may result in the cerebral blood flow reduction that cause hemodynamic stroke. Due to the rarity of this condition, there were no recommended therapeutics strategy. Mechanical reperfusion with PCI procedure may be a superior choice in the settings of acute cardio-cerebral infarction for restoring hemodynamic stability.

Background Electrocardiogram (ECG) is a widely accessible diagnostic tool that can easily be obtained on admission and can reduce excessive contact with coronavirus disease 2019 (COVID‐19) patients. A systematic review and meta‐analysis were performed to evaluate the latest evidence on the association of ECG on admission and the poor outcomes in COVID‐19. Methods A literature search was conducted on online databases for observational studies evaluating ECG parameters and composite poor outcomes comprising ICU admission, severe illness, and mortality in COVID‐19 patients. Results A total of 2,539 patients from seven studies were included in this analysis. Pooled analysis showed that a longer corrected QT (QTc) interval and more frequent prolonged QTc interval were associated with composite poor outcome ([WMD 6.04 [2.62‐9.45], P = .001; I 2:0%] and [RR 1.89 [1.52‐2.36], P, Electrocardiography abnormalities on admission, including longer QTc interval and prolonged QTc interval, longer QRS duration, a faster heart rate, the presence of LBBB, PAC, PVC, T‐wave inversion, and ST‐depression are significantly associated with an increased composite poor outcome in patients with COVID‐19.

The increasing rate of cardiovascular disorders contributes to rising hospitalized patients receive chronic oral beta-blocker therapy. Beta-blockers remain one of the fundamental therapy for chronic heart failure. Still, their role in decompensated heart failure and severe sepsis during hospitalization is often debated and inconsistent in clinical practice. In recent years, evidence of the efficacy and clinical outcomes of beta-blockers in acute heart failure (AHF) have accumulated. Clinical research indicates that chronic beta-blockade withdrawals should be prevented, or as soon as hemodynamic stabilization and euvolemic condition are reached, it should be reinstituted. As a subset of AHF patients with low cardiac output required inotropes, the choice of proper agent is fundamental. Different inotropic agents such as inhibitors of the phosphodiesterase, levosimendan, and dobutamine also their associations with beta-blockers are discussed.

The left main coronary artery (LMCA) ST-elevation myocardial infarction has been associated with significant morbidity and mortality. Older age and cardiogenic shock are independent predictors for in-hospital mortality. Here, we report a case of an 89-year-old Javanese man with a history of smoking presented with total LMCA occlusion complicated by cardiogenic shock in an octogenarian that was saved by stenting in thrombolysis in myocardial Infarction Flow III right coronary artery.

Hypertension is one of the most common morbidities in COVID-19. Previous studies demonstrated that hypertension increases composite poor outcomes in patients with COVID-19. Beta-blockers is widely used as one of the most common antihypertensive agents. Beta-blockers may hold potential benefits in COVID-19 treatment, with current evidence of the potential mechanism of beta-blockers remains scarce. However, several mechanisms were suggested, including decreasing RAAS pathway activity and lowering the ACE2 levels, reducing cytokine storms, and may be beneficial in reducing mortality in ARDS related COVID-19. Further large-scale randomized clinical trials should be conducted before a definite recommendation can be drawn.

Indonesian Basic Health Research in 2018 showed the prevalence of pneumonia, pulmonary tuberculosis (TB) and lung cancer in Indonesia 4.0% 0.4% and 0.18%, respectively. However, the number of lung specialists is small. According to the Indonesian Lung Specialist Association webpage, the number of doctors joined in the association up to 2008 were 452. This amount is very less when compared with existing lung disease cases. Thus, the handling of lung disease will be too late. The use of ANFIS for early detection of lung disease is growing. However, the systems designed are need preprocessing data to be executed and still applied for one type of disease. This paper will design a desktop application based on ANFIS expert system to detect lung disease early, i.e. for pneumonia, pulmonary TB and lung cancer. The system will work based on simple symptoms expressed by the patient. Subtractive clustering is used for clustering process. The results of the training showed that the models were able to give better performance compared to the model built using conventional clustering methods. The test results show that those three models have comparable performance compared to their counterpart. Software validation shows that the it gives 94.00% succeed for training data and up to 100% for testing data. This application is not intended to replace the role of a doctor, but to help diagnose the patient's condition earlier.

Background Venous thromboembolism (VTE) encompasses pulmonary embolism (PE), and deep vein thrombosis (DVT) is a common complication of cancer. Cancer manifestation in cardiac often secondary from the metastatic process, mostly in the pericardium. These concomitant findings of PE, DVT, and hemorrhagic cardiac tamponade as the first signs of cancer in a young patient is rare. Case Summary A 39-years-old man was referred to the emergency department from secondary hospital with the main complaint of dyspnea that onset abruptly two days before admission and swollen of the entire right leg since one week before. We report concomitant finding of hemorrhagic cardiac tamponade, deep vein thrombosis, and acute pulmonary embolism as initial presentations of occult malignancy. Starting anticoagulant in the hemorrhagic state and finding the primary cancer were problematic and challenging. Discussion The challenge in management, posed by hemorrhagic versus thrombosis state in cancer, prompted us to cautiously deliver the treatment with consideration of benefit over the risk. Primary cancer is not always easy to identify. Comprehensive (re-)evaluation is mandatory.

Chronic kidney disease (CKD) is progressive disease that closely related to the chronic inflammatory process.Angiotensin-Converting Enzyme Inhibitor (ACE-I)/Angiotensin Receptor Blockers (ARBs) is the main therapy in the management of CKD, based on the recent sudies stated that this drug have pleiotropic effects as anti-inflammation.The aim of this study is tosee the interaction of hs-CRP and HDL-Cholesterol to prove the role of ACE-I/ARBs as an anti-inflammatory treatment for CKD patient. In this study we compared hs CRP, HDL Cholesterol and HDL Cholesterol /hs-CRP ratio levels in CKD patients who consumeand do not consumeACE-I/ARBs. Forty eight samples of CKD patients were taken randomly and then separated into two group based on their consumption of ACE-I/ARBs, each group have 24 samples.There were significantly different of mean of hs-CRP, HDL Cholesterol, and HDL Cholesterol/hs-CRP ratio between group, the mean concentration of hs-CRP in the ACE-I/ARBs group was significantly lower than in non-ACE-I/ARBs group (1,48±0,81 vs 4,19±4,02; P= 0.038),the mean of HDL (48,95±13,05vs 41,50±12,31; P= 0,048).There were negative correlation between HDL Cholesterol and hs-CRP, positive correlation between HDL Cholesterol/hs-CRP ratio and eGFR.This result indicate that hs-CRP and HDL-Cholesterol monitoring very important in CKD patient.

Heart disease is the leading cause of death in the world. To find out heart disease early, it can be detected by examining the presence or absence of arrhythmias. Arrhythmia is an abnormal heart beat rhythm, can beat too fast, too slow, or beat with irregular patterns, so that the arrhythmia has many types. To diagnose arrhythmias, one method that can be used is by analyzing ECG (Electrocardiogram) signals. Currently, doctors and medical personnel analyze ECG signals manually. Because the number of cardiologist paramedics is far less than the number of patients, patients need hardware or software to analyze the heart independently. With the development of technology in this era, there is a technology called Deep Learning. Deep Learning is a development of Machine Learning. In this paper, we proposed one method of Deep Learning, namely Convolutional Neural Network (CNN), is used to classify 5 types of arrhythmias on ECG signals, that are: Normal Beat (NOR), Right Bundle Branch Block (RBBB), Left Bundle Branch Block (LBBB), Premature Ventricular Contraction (PVC) and Fusion of Ventricular and Normal (FVN). Evaluating the performance of our CNN architecture, we tested it to classify the heart beat in the MIT BIH Arrhythmia database. The performance results of our proposed have highest accuracy is 98.6% with the following details: 713 Normal Beat samples can be detected correctly (100%), RBBB 689 samples (96.63%), LBBB 710 samples (99.58%), FVN 713 samples (100%), and PVC 690 samples (96.77%).

Aims This meta-analysis aims to analyze the association of calcium channel blocker (CCB) use with COVID-19 clinical outcomes. Methods PubMed, ProQuest, Science Direct, Scopus, and medRxiv databases were searched systematically in a limited period. The primary outcome was mortality. Results A total of 119,298 patients from 31 eligible studies were included. Pooled analysis of the random-effect model revealed CCB was not associated with reduced mortality (OR = 1.21 [95%CI: 0.98–1.49], p = 0.08). Interestingly, subgroup analysis in hypertensive patients revealed significantly reduced mortality (OR = 0.69 [95%CI: 0.52–0.91], p = 0.009). Conclusion CCB usage was not associated with the outcome of COVID-19. However, CCB was associated with a decreased mortality rate in hypertensive COVID-19 patients.

We present a case of acute left main bifurcation lesion presenting as very high-risk non-ST elevation acute coronary syndrome. Consequently, an immediate invasive strategy for this complex anatomical lesion in an unstable patient requires an emergent bailout strategy to restore the haemodynamic condition.Our case shows the simultaneous kissing stents technique in a patient with a true left main bifurcation lesion (Medina 1-1-1) as a strategy to overcome the compromised haemodynamics. This protocol would be an alternative life-saving strategy in an acute setting.

Acute pericarditis is a common disorder caused by inflammation of the pericardium and can occur as an isolated entity or as a manifestation of an underlying systemic disease. The diagnosis of acute pericarditis is established when a patient has at least two of the following symptoms or signs: chest pain consistent with pericarditis, pericardial friction rub, typical ECG changes, or a pericardial effusion of more than trivial size. Systemic Lupus Erythematosus (SLE) is a chronic autoimmune systemic disorder with unknown etio-pathogenesis. Upon the susceptible genetic, hormonal and abnormal immunologic background, the environmental factors may play role as trigger to permit disease development. Cardiovascular complications occur in more than half of the patients with SLE. Pericarditis is the most studied cardiovascular manifestation, although often not evident clinically, and it is included in the American College of Rheumatology (ACR) classification criteria for SLE. We report a clinical case of initially unremarkably findings which progressed to SLE complicated by full-blown acute pericarditis. A brief review of acute pericarditis, including etiology, clinical presentation, ECG criteria, echocardiographic manifestation, and treatment is presented. Abstrak Perikarditis akut adalah penyakit yang disebabkan oleh inflamasi dari perikard, dapat terjadi sebagai entitas penyakit primer maupun sekunder sebagai manifestasi dari penyakit sistemik yang mendasarinya. Diagnosis perikarditis akut ditegakkan saat pasien mengalami setidaknya dua dari tanda atau gejala berikut: nyeri dada spesifik perikarditis, pericardial friction rub, perubahan EKG tipikal, atau adanya efusi perikard dengan ukuran lebih dari trivial. Lupus Eritematosus Sistemik (LES) adalah penyakit autoimun sistemik kronis dengan etiopatogenesis yang belum diketahui. Adanya kepekaan genetik, latar belakang imunologis abnormal dan hormonal, serta faktor lingkungan memegang peran sebagai pemicu perkembangan penyakit. Komplikasi kardiovaskular terjadi pada lebih dari setengah pasien dengan SLE. Perikarditis merupakan manifestasi kardiovaskular yang paling sering dijumpai, meskipun jarang ditemukan patognomonis secara klinis, dan termasuk dalam kriteria klasifikasi LES menurut American College of Rheumatology (ACR). Berikut kami laporkan kasus dengan presentasi klinis febris dan takikardia yang kemudian mengarah pada LES dengan komplikasi perikarditis akut. Kami sertakan juga ulasan tentang perikarditis akut, termasuk etiologi, presentasi klinis, kriteria EKG, manifestasi ekokardiografis, dan terapi.

Introduction:Patients with CKD have elevated plasma levels of Asymmetrical Dimethyl Arginine (ADMA), impaired EDRF/NO responses in isolated resistance vessels, and a marked increase in the frequency of cardiovascular events that are predicated by plasma levels of ADMA. ADMA is considered as a risk factor for endothelial dysfunction, progression of chronic kidney disease and a marked increase in the frequency of cardiovascular events that are predicated by plasma levels of ADMA. Elevated ADMA in CKD have been related to a combination of a reduced renal ADMA excretion and a reduced catabolism of ADMA by dimethylarginine dimethylaminohydrolase (DDAH). The current study was undertaken to determine whether there is a correlation between ADMA and SNPs at -449 DDAH 2.Subjects and Methods :It was a cross sectional analytic study, 56 hemodialysis patients and 30 healthy individuals were enrolled. Based on its etiology, HD patients group was further divided in to hypertension (HT) subgroup and non-HT subgroup. Genotyping of the polymorphisms was performed using PCR-based SNP detection methods based on 5’-exonuclease activity assays for rs805305.Results :Heterozygotes were observed as the most abundant genotypes in both groups, followed by GG genotype in the HD patients (30%) and CC (27%) healthy individuals. Among the HT subgroup, the mean plasma levels of ADMA were sequentially higher from genotypes CC, G/C and GG (p = 0.037). Further multiple comparisons between groups using post hoc test showed results that genotype GG and CC were different at 0.05 level of significance. These findings were not found among non HT subgroup.Conclusion: Genetic variation in the DDAH 2 genes is significantly associated with serum ADMA levels in hypertensive HD patients. We observed that carriage of a G at position -449 in the promoter region of the DDAH 2 gene is associated with higher ADMA levels.

The prevalence of hepatitis C virus (HCV) infection has been as high as approximately 80% in patients with maintenance hemodialysis in public hospitals in Indonesia. However, the prevalence in private hospitals has not been examined yet. The aim of this study was to investigate the prevalence of anti-HCV antibody and the subtype distribution in patients with hemodialysis in a private hospital in Surabaya, Indonesia. Sera were obtained from 41 hemodialysis patients in a private hospital in Surabaya. The positive prevalence of anti-HCV antibody was carried out by the enzyme-linked immunosorbent assay (ELISA). Anti-HCV-positive sera were subjected to reverse transcription-PCR (RT-PCR) to detect HCV RNA and then direct sequencing. The HCV subtype was examined by phylogenetic analysis. Twenty five patients (61%) out of 41 were positive for anti-HCV antibody, and HCV-RNA was detected in 19 patients. The positive prevalence of anti-HCV antibody was 7.7% (one out of 13 patients) among patients who had undergone hemodialysis for less than one year, whereas it was 85.7% (24 out of 28 patients) among patients who had undergone hemodialysis for over one year. Phylogenetic analysis revealed HCV-1a (52.6%) was the most common subtype, followed by 1b (15.8%), 1c (15.8%), 2a (5.3%), and 3k (5.3%). In conclusion, the prevalence of HCV infection among hemodialysis patients in a private hospital was as high as that in general hospitals. The predominant subtype was HCV-1a, which is in accordance with the previous studies in general hospitals in Surabaya, Indonesia.

Background: Uremic patients are in a pro-oxidant state and show an increased level of asymmetric dimethylarginine (ADMA), which is due to increased PRMT1 activity and reduced dimethylarginine dimethylaminohydrolase (DDAH) as degradation enzymes. Reactive oxidant species may play an important role in increasing the action of PRMT1 and in inhibiting the action of DDAH. Albuminuria and ADMA are closely correlated with progression of cardiovascular disease in chronic kidney disease (CKD) patients as well as indicators for decreasing renal function. Although ACEIs and/or ARBs reduced albuminuria in CKD patients, the results are still conflicting. Several factors in these patients may play important roles in the mechanism of albuminuria such as oxidative stress. The antioxidant N-acetylcysteine may prove to have beneficial therapeutic effect, because it can reduce oxidative stress as shown by evidence in humans, and subsequently increase ADMA. The objective of the present study is to explore the contribution of the antioxidant N-acetylcysteine (NAC) to the decrease of ADMA and albuminuria in non-diabetic CKD patients. Material and Methods: Patients with non-DM CKD stage 1–4 with albuminuria were randomized to receive ACEI and/or ARB alone (control group) or with antioxidant NAC 600 mg orally twice a day (treatment group). Observations were performed for 3 months to measure ADMA and albuminuria before and after-treatment. 80 patients in total 40 in the control group and 40 in the treatment group were used. Results: After oral treatment with NAC, the plasma level of ADMA in the treatment group increased from 0.604 µmol/l to 0.689 µmol/l, whereas ADMA level in the control group exhibited a higher increase from 0.561 µmol/l to 0.743 µmol/l. The increases in these groups were significantly different (p < 0.02). Moreover, the level of albuminuria was reduced from 148.12 µg/mg • cr to 132.7 µg/mg • cr in the treatment group, and from 75.25 µg/mg • cr to 71.85 µg/mg • cr in the control group. The difference was significant (p < 0.001). Conclusion: The anti-oxidant N-acetylcysteine can be used as adjuvant therapy to inhibit the progression of CKD in patients by decreasing the ADMA level and albuminuria.
