The evolution of patients with COVID-19 is unpredictable, with an unfavorable evolution in the case of patients with comorbidities. This state-of-the-art review focuses on the role of hematological inflammatory biomarkers: the neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), and platelet-to-lymphocyte ratio (PLR) in predicting major adverse cardiovascular events (MACE) and mortality in patients with COVID-19. In this review, we included 21 studies that investigated the role of biomarkers in the risk of mortality and MACE, reporting on a total of 7,588 patients. Regarding the clinical data, 57.49% of the patients presented hypertension (15 out of the 21 studies reported hypertensive patients), followed by ischemic heart disease in 33.56% of patients (13 studies) and diabetes in 30.37% of patients (17 studies). In additional, among the usual risk factors, 23.55% of patients presented obesity (7 studies) and 23.02% were active smokers (10 studies). We recorded an average cut-off value of 7.728 for NLR (range 2.6973–15.2), 0.594 for MLR (range 0.26–0.81), and 215.07 for PLR (range 177.51–266.9) for the risk of MACE and mortality. We also recorded an average area under the curve (AUC) of 0.783 for NLR, 0.744 for MLR, and 0.713 for PLR. Our findings suggest that these biomarkers exhibit prognostic value in predicting adverse outcomes, and that evaluating these biomarkers at admission could provide novel information in stratifying risk groups for improving patient management.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/jce-2024-00102024-06-27T00:00:00.000+00:00Heart Failure as the First Clinical Manifestation of Basedow’s Diseasehttps://sciendo.com/article/10.2478/jce-2024-0012<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Introduction</title> <p>Thyroid hormones influence multiple systems, but most often the impact on the cardiovascular system is what brings the patient to the emergency department.

The risk of rupture and, therefore, mortality is increased significantly in AAA. The role of the mechanical characteristics of the AAA wall is poorly studied.</p> <p>The <bold>aim</bold> of this study was to determine the mechanical properties of each layer of the porcine abdominal aorta for a better understanding of the role of the microstructural elements of the arterial wall in the development and risk of AAA rupture.</p></sec> <sec><title style='display:none'>Materials and methods</title><p>In this study, eight tubular segments of the abdominal porcine aorta were examined. From these segments, we processed 13 × 13 mm square samples for biaxial analysis and 15 × 5 mm samples for uniaxial analysis. At the biaxial analysis, the intact wall and each layer (intima, media, and adventitia) were stretched by 25% at a speed of 1% per s and we determined the mechanical characteristics of the samples at the point of failure.</p></sec> <sec><title style='display:none'>Results</title><p>In the circumferential axis, we found the adventitia (0.233 MPa) to be stronger than the media (0.182 MPa, p = 0.007), intima (0.171 MPa, p = 0.008), and the intact wall (0.192 MPa, p = 0.045). In the longitudinal axis, the adventitia (0.199 MPa) was stronger than the intima (0.117 MPa, p &lt;0.001) and the intact wall (0.156 MPa, p = 0.045), but there was no statistically significant difference compared to the media. Additionally, the adventitia had a greater stiffness than the other two layers (p &lt;0.05 for both layers and axes) and the intact wall (p &lt;0.05 for both axes). Stretching until failure, the adventitia was the strongest compared to the other layers and the intact wall (p &lt;0.001 for all), and it also presented better compliance, with the highest stretch ratio.</p></sec> <sec><title style='display:none'>Conclusions</title><p>The results indicate that the adventitia layer is the strongest and stiffest compared to the other two layers, being the last mechanical resistance structure of the arterial wall. It is crucial to avoid injuring and aggressively manipulating the adventitia during surgery to maintain the vascular wall's resistance structure.

The inflammatory response in these diseases, characterized by increased levels of neutrophils and platelets, highlights the importance of prompt management. The neutrophil-to-lymphocyte ratio (NLR) has emerged as a useful biomarker during the COVID-19 pandemic and high NLR levels were found to be associated with an increased risk of ALI and other thromboembolic events. The aim of this systematic review was to analyze the prognostic role of the NLR regarding the risk of amputation and mortality in patients diagnosed with ALI and CLTI. We included 12 studies (five for ALI, with 1,145 patients, and seven for CLTI, with 1,838 patients), following the PRISMA guidelines. Treatment results were evaluated, including amputation and mortality. We found that high NLR values were consistently associated with an increased risk of amputation and/or mortality, with pooled odds ratios ranging from 1.28 to 11.09 in patients with ALI and from 1.97 to 5.6 in patients with CLTI. The results suggest that NLR may represent an important tool for informed decision-making in the management of these patients.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/jce-2024-00062024-03-21T00:00:00.000+00:00Critical Appraisal of Medical System Performance for STEMI Management – a Comprehensive Analysis of Time Efficiencyhttps://sciendo.com/article/10.2478/jce-2024-0008<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Background</title> <p>Time intervals related to ST-segment myocardial infarction (STEMI) revascularization are central determinants for patient outcomes.

The main time intervals were the following: patient delay 209 min, emergency medical system delay 66 min, and PCI center delay at 70 min, totaling an ischemic time of 6.4 h. A provisional stop at another hospital involved the addition of 113 min (1.8 h) until STEMI diagnosis and an additional 83 min (1.3 h) from diagnosis to revascularization, totaling a supplementary ischemic time of 3.1 h. In total, 41.5% of the patients were revascularized between 2 and 6 h from symptoms onset. The objective of revascularization in less than 120 min (from first medical contact) was accomplished in 35.5% of the patients.

Accurate diagnosis may be difficult and, in very rare cases, can mimic ST-elevation myocardial infarction (STEMI). We present the case of a 44-year-old man, with clinical, ECG, and ultrasound criteria of inferior STEMI. Emergency coronary angiography excluded obstructive coronary artery disease. However, a hydroaeric level image in the pericardium drew our attention. The chest computed tomography scan and Gastrografin study confirmed the diagnosis of pyopneumopericardium. An exploratory thoracotomy was performed to drain the liquid from the pericardium, without highlighting a fistulous path. The etiology of the pyopneumopericardium was detected by performing an upper endoscopy, which revealed a complex lesion suggestive for a foreign body perforation, which was treated with a covered esophageal stent.

This review emphasizes the urgency of timely recognition and intervention, as a notable proportion of affected neonates face critical illness shortly after birth. The multidisciplinary approach involving neonatologists, pediatricians, and obstetricians is essential to address the diagnostic and therapeutic challenges inherent in neonatal cardiac emergencies. The insights presented herein aim to guide medical practice, enhance early recognition, and ultimately improve outcomes for newborns grappling with critical heart conditions. Key proactive measures advocated include prenatal screening, facilitating early identification of potential cardiac anomalies. Advanced imaging techniques, such as fetal echocardiography, have a crucial role in enabling detailed examinations, contributing to the prenatal diagnosis of major CHDs. The review underscores the importance of preparing medical teams during the prenatal period for potential postnatal complications, emphasizing the necessity of a holistic approach to the care of neonates who survive critical episodes. Continued research and clinical advancements remain imperative to refine strategies and optimize care for this vulnerable patient population. The provided data serve as a valuable guide for healthcare professionals and could improve the outcomes of neonates confronting the challenges of CHD.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/jce-2024-00022024-02-10T00:00:00.000+00:00The Risk of Death among Patients with Healthcare-associated Infections and Cardiovascular Diseases Admitted to the Intensive Care Unit in Romaniahttps://sciendo.com/article/10.2478/jce-2024-0001<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Background</title><p>Healthcare-associated infections (HAIs) can pose significant risks to patients with cardiovascular disease due to the compromised nature of their health and potential vulnerabilities.

Recognizing the early warning signs is crucial for highlighting the need for immediate medical attention, especially since a quick intervention may significantly improve short and long-term patient outcome. Artificial intelligence (AI) has become a key technology in healthcare, and especially in the cardiovascular field. AI, and in particular deep learning is well suited for automatically analyzing medical images, signals, and data. Its success rests on the availability of large amounts of curated data, and the access to high performance computing infrastructures for training the deep-learning algorithms. Thus, in cardiovascular care, AI plays a dynamic role in disease detection, predicting disease outcome, and guiding treatment decisions. This review paper details and discusses the current role of AI for the most common cardiovascular emergencies. It provides insight into the specific issues, risk factors, different subtypes of the diseases, and algorithms developed to date, followed by an outlook.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/jce-2023-00192023-12-10T00:00:00.000+00:00Multiple Implantable Cardioverter-Defibrillator Shocks in Ischemic Cardiomyopathy Compels Coronary Vascularization Reassessmenthttps://sciendo.com/article/10.2478/jce-2023-0017<abstract> <title style='display:none'>Abstract</title> <p>The increasing number of patients with heart failure and implantable cardioverter-defibrillators (ICD) has led to a growing of the emergency presentations for ICD internal shocks. Appropriate shocks are sometimes caused by acute events in the course of disease and could be one of the earliest symptoms contributing to the diagnosis and timely treatment of these acute conditions. We present the case of a 64-year-old male patient with ischemic cardiomyopathy, ICD carrier, who presented to the emergency department for recurrent appropriate ICD shocks caused by episodes of polymorphic ventricular tachycardia and ventricular fibrillation. Even if he did not have chest pain, he was referred to cath lab, where the coronary angiography has shown a severe stenosis at the origin of the left anterior descending artery and a moderate stenosis at the proximal left circumflex artery. The percutaneous revascularization of both lesions resulted in the eradication of the sustained ventricular arrhythmias and the improvement of the clinical status. The case argues for the need for coronary vascularization assessment in ICD carrier patients with ischemic heart failure and adequate recurrent shocks, also emphasizing the importance of remote monitoring in early diagnosis of acute conditions in these patients.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/jce-2023-00172023-12-10T00:00:00.000+00:00Bioengineered Small-Diameter Vascular Xenografts as an Alternative to Autologous Vascular Grafting for Emergency Revascularization – a Preliminary Studyhttps://sciendo.com/article/10.2478/jce-2023-0021<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Background</title> <p>Autologous vascular arterial or venous graft are not available in 10-40% of patients, due to vascular pathologies, and the utility of decellularized biological scaffolds would be a solution for those cases.

In some patients, HCPS can have a severe evolution, with rapid progression to respiratory distress and cardiogenic shock. We present the case of a 56-year-old female patient who was transferred to our hospital with ST-segment elevation myocardial infarction (STEMI) and acute respiratory distress syndrome (ARDS). The coronary angiography showed normal epicardial coronary arteries and the lung computed tomography (CT) raised the suspicion of tracheoesophageal fistula, which was soon refuted by an upper digestive endoscopy. Initially, the evolution was very severe, requiring mechanical ventilation, hemodynamic support, and broad-spectrum antibiotics. Later, sero-logical testing revealed an acute infection with Hantavirus Dobrava type. The patient lives in a rural environment, working in a wheat mill. Despite the severe presentation, the evolution was favorable, with complete remission of the pulmonary and myocardial damage after 2 weeks. We emphasize the importance of HCPS suspicion and specific testing in the early phase of the disease, as well as early admission to an intensive care unit, which is crucial in severe cases and can improve survival in a patient without any specific symptoms or a clear diagnosis.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/jce-2023-00202023-12-10T00:00:00.000+00:00Regional Differences in the Level of Inflammation Between the Right and Left Coronary Arteries – a Coronary Computed Tomography Angiography Study of Epicardial Fat Attenuation Index in Four Scenarios of Cardiovascular Emergencieshttps://sciendo.com/article/10.2478/jce-2023-0014<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Introduction</title> <p>The pericoronary fat attenuation index (FAI) is an emerging computed tomography-derived marker for measuring vascular inflammation at coronary vessels.

FAI values showed a significantly higher level at the RCA (−71.25 ± 7.47 HU) compared to the LCX (−76 ± 7.68 HU) and the LAD (−73.04 ± 8.9 HU, p &lt;0.0001). This trend persisted across all subgroups, including post-COVID CT scans (−75.49 ± 7.62 HU for RCA vs. −72.89 ± 9.40 HU for the LCX vs. −71.28 ± 7.82 HU for the LAD, p = 0.01) and patients with high-risk plaques (20.98 ± 16.29 for the RCA vs. 11.77 ± 7.68 for the LCX vs. 12.83 ± 6.47 for the LAD, p = 0.03).</p> </sec> <sec><title style='display:none'>Conclusion</title> <p>Plaques in different coronary areas show varied vulnerability and inflammation levels.

CCTA identifies high-risk plaques, and the latest CT technologies based on calculation of fat attenuation index (FAI) allow assessment of inflammation at the level of the target coronary artery. We present a series of case studies with chest pain and positive CCTA, in whom a significant stenosis was detected in the left anterior descendent coronary artery, and the existence of high-risk, inflamed plaques was documented even in the context of a zero calcium score. A severe narrowing of the left anterior descending artery, exhibiting the pattern of high-risk anatomy, was associated with a very high inflammation depicted by FAI analysis in all three cases, an association that may be extremely dangerous. In this case series, CCTA examination led to immediate stenting of the obstructive stenosis, sealing the dangerous plaque.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/jce-2023-00162023-12-09T00:00:00.000+00:00High Inflammation and Coronary Calcification in an Acute Coronary Syndrome Successfully Treated with Cutting Balloonhttps://sciendo.com/article/10.2478/jce-2023-0015<abstract> <title style='display:none'>Abstract</title> <p>Complex coronary atherosclerosis may exhibit different phenotypes of coronary plaques, from non-calcified highly vulnerable atheroma to heavily calcified ones. Computed coronary tomography angiography (CCTA) may identify these different phenotypes and the recently introduced CCTA-based techniques for mapping coronary inflammation along the coronary arteries may provide useful additional information on cardiovascular risk. Here we present the case of a 68-year-old male patient with acute coronary syndrome in whom invasive coronary angiography and CCTA revealed a severe three-vessel disease with a heavily calcified lesion. Mapping of the CT fat attenuation index along the coronary arteries identified a high level of coronary inflammation, especially associated with the non-calcified lesions. All lesions were successfully revascularized by implantation of drug-eluting stents. A cutting balloon was used for the lesion identified by CCTA as heavily calcified, followed by stent implantation, with good results. In conclusion, CCTA, in association with novel techniques for mapping coronary inflammation, may represent an extremely useful tool for preparing complex interventions in multivessel diseases, helping preprocedural planning in high-risk patients.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/jce-2023-00152023-12-09T00:00:00.000+00:00en-us-1
