Inflammation, Immunity, and Hypertension

The immune system, inflammation and hypertension are related to each other. Innate and adaptive immunity system triggers an inflammatory process, in which blood pressure may increase, stimulating organ damage. Cells in innate immune system produce ROS, such as superoxide and hydrogen peroxide, which aimed at killing pathogens. Long-term inflammation process increases ROS production, causing oxidative stress which leads to endothelial dysfunction. Endothelial function is to regulate blood vessel tone and structure. When inflammation lasts, NO bioavailability decreases, disrupting its main function as vasodilator, so that blood vessels relaxation and vasodilatation are absent. Effector T cells and regulatory lymphocytes, part of the adaptive immune system, plays role in blood vessels constriction in hypertension. Signals from central nervous system and APC activates effector T lymphocyte differentiation and accelerate through Th-1 and Th-17 phenotypes. Th-1 and Th-17 effectors participate in inflammation which leads to increased blood pressure. One part of CD4+ is the regulatory T cells (Tregs) that suppress immune response activation as they produce immunosuppressive cytokines, such as TGF-β and IL-10. Adoptive transfer of Tregs cells can reduce oxidative stress in blood vessels, endothelial dysfunction, infiltration of aortic macrophages and T cells as well as proinflammatory cytokine levels in plasma circulation

NSTEMI with total left circumflex occlusion: how the N-wave might help

A rise and/or fall in troponin level is an indication of type 1 or 2 myocardial infarct. A 62-year-old male physician presented to emergency room with chest discomfort followed by thought to be normal electrocardiogram (ECG) and normal echocardiography results. His serial hs-troponin test showed remarkable escalation three hours from the initial (107 ng/l into 4.978 ng/l), suggesting a high-risk non-ST-segment myocardial infarction (NSTEMI). An early invasive procedure was performed, showing acute total occlusion (TO) in the obtuse marginal 1 branch. We retrospectively reviewed our examination to diagnose better the presence of TO in NSTEMI patients presented with non-diagnostic examination. Our evaluation showed a minor change in the form of an ‘N-wave’ pattern on the ECG, which was not yet an established guideline criterion for prompt angiography. Although ECG pattern is often normal in LCx occlusion, recent study shows the presence of ‘N-wave’ ECG pattern in 10% of NSTEMI cases following TO at LCx

Detection of multi-class arrhythmia using heuristic and deep neural network on edge device

Heart disease is a heart condition that sometimes causes a person to die suddenly. One indication is a rhythm disorder known as arrhythmia. Multi-class Arrhythmia Detection has followed: QRS complex detection procedure and arrhythmia classification based on the QRS complex morphology. We proposed an edge device that detects QRS complexes based on variance analysis (QVAT) and the arrhythmia classification based on the QRS complex spectrogram. The classifier uses two-dimensional convolutional neural network (2D CNN) deep learning. We use a single board computer and neural network compute stick to implement the edge device. The outcomes are a prototype device cardiologists use as a supporting tool for analysing ECG signals, and patients can also use it for self-tests to figure out their heart health. To evaluate the performance of our edge device, we tested using the MIT-BIH database because other methods also use the data. The QVAT sensitivity and predictive positive are 99.81% and 99.90%, respectively. Our classifier's accuracy, sensitivity, predictive positive, specificity, and F1-score are 99.82%, 99.55%, 99.55%, 99.89%, and 99.55%, respectively. The experiment result of arrhythmia classification shows that our method outperforms the others. Still, for r-peak detection, the QVAT implemented in an edge device is comparable to the other methods. In future work, we can improve the performance of r-peak detection using the double-check algorithm in QVAT and cross-check the QRS complex detection by adding 1 class to the classifier, namely the non-QRS class

Myocardial injury mimicking acute myocardial infarction due to coronavirus infection in adults with pre-existing apical hypertrophic cardiomyopathy

Symptoms of apical hypertrophic cardiomyopathy (ApHCM) can mimic acute myocardial infarction (AMI). Following COVID-19 infection, the elevation of troponin in ApHCM might be confusing, due to its similarity with AMI. We report the case of a 64-year-old male patient presenting with exertional dyspnoea and chest discomfort. He had no history of coronary artery disease (CAD), but his swab test was positive for COVID-19. The physical examination was normal. The 12-lead electrocardiogram showed a sinus rhythm of 78 bpm, with deep inverted T waves in leads V2 to V6, I, and aVL, and left ventricular hypertrophy. An Echocardiographic examination showed an 18 mm apical wall thickness of the left ventricle. Laboratory tests revealed elevated hs- Troponin level, but diagnostic coronary angiography was normal. The diagnostic criteria fulfilled apical cardiac hypertrophic cardiomyopathy. Coronavirus can induce atypical cardiovascular symptoms in pre-existing ApHCM. Misdiagnosis and failure to recognize may result in inappropriate therapy and delay in definitive treatment.

Acute Pericarditis in Patient with Systemic Lupus Erythematosus: A Case Report

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

Predicting the pro-longevity or anti-longevity effect of model organism genes with enhanced Gaussian noise augmentation-based contrastive learning on protein-protein interaction networks

Ageing is a highly complex and important biological process that plays major roles in many diseases. Therefore, it is essential to better understand the molecular mechanisms of ageing-related genes. In this work, we proposed a novel enhanced Gaussian noise augmentation-based contrastive learning (EGsCL) framework to predict the pro-longevity or anti-longevity effect of four model organisms’ ageing-related genes by exploiting protein–protein interaction (PPI) networks. The experimental results suggest that EGsCL successfully outperformed the conventional Gaussian noise augmentation-based contrastive learning methods and obtained state-of-the-art performance on three model organisms’ predictive tasks when merely relying on PPI network data. In addition, we use EGsCL to predict 10 novel pro-/anti-longevity mouse genes and discuss the support for these predictions in the literature

Simultaneous kissing stents in acute left main total occlusion complicated with cardiogenic shock

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

Case Report: Wellens syndrome in acute critical coronary occlusion saved by collateral [version 3; peer review: 2 approved]

Background It is important and challenging to distinguish between acute myocardial infarction and Wellens syndrome due to its time to intervention. Difficulties in differentiating between subtypes could mean the patients are overtreated or receive undertreatment. Case report A 57-year-old man was referred to our emergency ward with acute onset of chest pain. Electrocardiograms changes were suggestive of type A Wellens syndrome. Nitroglycerin was administrated, the patient's chest pain disappeared, and we planned an early invasive strategy. He had a previous documented electrocardiogram before he went for catheterization and based on the second electrocardiogram changes were suggestive of an ST-elevation. As the result of the invasive strategy, it was found that there was single-vessel disease, critical occlusion in the middle of the left anterior descending artery coronary artery with collateral from the right coronary artery. After two days of observation in the Intensive Cardiovascular Care Unit, the patient improved and was transferred to Low Care Unit. Conclusions The case highlights Wellens syndrome in acute critical occlusion with collateral artery
