ZusammenfassungUm Schlaganfall-Patienten eine effiziente Sekundärprophylaxe anbieten zu können, ist eine strukturierte Diagnostik hinsichtlich der vermuteten Schlaganfallätiologie auf einer Stroke Unit unabdingbar. Bei den ätiologisch „kryptogenen” Schlaganfällen wird zunehmend ein paroxysmales Vorhofflimmern (pVHF) als mögliche auslösende Ursache gefunden. Lässt sich das permanente Vorhofflimmern (VHF) einfach durch ein 12-Kanal-EKG detektieren, kann das häufig klinisch asymptomatisch und in Clustern auftretende pVHF diagnostische Schwierigkeiten bereiten. Aktuelle Studien konnten belegen, dass ein prolongiertes EKG-Monitoring über die derzeit empfohlenen 24 Stunden hinweg häufiger zur Detektion von pVHF führt. Dies hat direkte sekundärprophylaktische Konsequenzen, da in den meisten Fällen dann eine orale Antikoagulation indiziert ist. Sowohl permanentes als auch pVHF sind mit einem erhöhten Re-Schlaganfallrisiko vergesellschaftet. Insbesondere vor dem Hintergrund der Effektivität direkter oraler Antikoagulantien, kommt damit der Diagnostik von pVHF eine besondere Bedeutung zu. In der vorliegenden Übersicht werden die Möglichkeiten einer optimierten pVHF Diagnostik diskutiert.

ABSTRAK Pendahuluan: Acute ischemic stroke (AIS) merupakan jenis stroke dengan insidensi tertinggi utamanya pada kelompok usia lanjut. Saat ini, neuroimaging menjadi modalitas utama dalam penegakan diagnosis stroke, akan tetapi masih memiliki beberapa kelemahan, seperti ketersediaan yang terbatas, biaya yang mahal, waktu yang cukup lama untuk prosedurnya, serta pada beberapa kasus ditemukan hasil interpretasi gambar yang sering tidak konsisten pada stroke fase awal. Sehingga diperlukan alat diagnostik yang cepat, tepat, dan sederhana untuk diagnosis AIS. Saat ini, tipe tertentu dari circulating microRNAs (miRNAs) ditemukan dapat menjadi biomarker untuk diagnostik AIS. Tujuan kajian ini untuk melakukan profiling sekaligus mengevaluasi nilai diagnostik circulating miRNA pada pasien AIS dibandingkan dengan pasien hemorrhagic stroke (HS) dan individu sehat. Metode: Tinjauan sistematis ini mengumpulkan literatur dari PubMed, Science Direct, Clinical Trial.gov, Directory of Open Access Journal (DOAJ), dan Epistemonikos menggunakan metode standar dengan pedoman cochrane untuk tinjauan sistematis guna mengevaluasi nilai diagnostik dari circulating miRNA sebagai biomarker untuk AIS berdasarkan sensitivitas, spesifitas, dan nilai Area Under the Curve (AUC). Pembahasan: Dari 870 studi, 15 studi sesuai dengan kriteria inklusi. Dari studi yang ditinjau menunjukkan bahwa hsa-miR-106b-5P dan kombinasi miR-125a-5p + miR-125b-5p + miR-143-3p sebagai jenis miRNA yang paling efektif menjadi biomarker dalam mendiagnosis AIS dan membedakannya dengan individu sehat. Sedangkan miR-124-3p merupakan jenis miRNA yang paling efektif menjadi biomarker untuk membedakan AIS dan HS. Simpulan: Circulating miRNA yang diisolasi dari plasma, serum, dan darah manusia dapat digunakan sebagai biomarker diagnostik untuk AIS.

Annotation:

There is a large unmet need for fast and reliable diagnostics in several diseases. One such disease is stroke, where the efficacy of modern reperfusion therapies is highly time-dependent. Diagnosis of stroke and treatment initiation should be performed as soon as possible, and preferably before arrival at the stroke center. In recent years, several potential blood biomarkers for stroke have been evaluated, but without success. In this review, we will go into detail on the possibility of utilizing extracellular vesicles (EVs) released into the blood as novel biomarkers for stroke diagnostics. EVs are known to reflect the immediate state of the secreting cells and to be able to cross the blood–brain barrier, thus making them attractive as diagnostic biomarkers of brain diseases. Indeed, several studies have reported EV markers that enable differentiation between stroke patients and controls and, to a lesser extent, the ability to correctly classify the different stroke types. Most of the studies rely on the use of sophisticated and time-consuming methods to quantify specific subpopulations of the nanosized EVs. As these methods cannot be easily implemented in a rapid point of care (POC) test, technical developments followed by prospective clinical studies are needed.

The article is devoted to the urgent problem of pediatrics and pediatric neurology, pre-hospital diagnosis of stroke in children. A review of domestic and foreign literature on the early diagnosis of stroke in children and adolescents, as well as epidemiological data on pediatric stroke, is presented. Particular attention is paid to the features of the symptoms of stroke and stroke-like conditions («stroke masks») in the pediatric population and the analysis of the main factors that influence errors in the early diagnosis of stroke in children and adolescents. Currently, in the diagnosis of ischemic stroke, its «masks» are found in 53.9 % of cases, with hemorrhagic stroke, in 36.3 %, and with transient ischemic attacks, in 9.8 % of cases. One of the most common diseases with which it is necessary to differentiate ischemic stroke in children is migraine. This problem is covered in academic writings that highlight the leading differential diagnostic criteria for migraine and stroke, and also represent a diagnostic algorithm. The clinical features of pediatric stroke, especially manifest symptoms, make it difficult to apply adult screening stroke scales in pediatrics. The article discusses the main scales for the early diagnosis of stroke in adults, and their potential application in pediatric practice. Currently accumulated experience in prehospital and early diagnosis of stroke in children determines the main directions of work to reduce the time of diagnosis of acute cerebrovascular accidents in children, followed by the introduction of reperfusion therapy in pediatric practice.

Investigations were carried out in 24 patients in order to evaluate information value of the data of clinical, laboratory, neuroradiological methods of research and develop the diagnostic algorithm in case of cerebral venous thrombosis (CVT). The main group consisted of 11 patients (7 male, 4 female, average age 49,1±4,3) with CVT. The comparison group included 13 patients (6 male, 7 female; average age 68,1±9,5) with ischemic stroke (IS) of moderate severity. There were revealed changes in blood and cerebrospinal fluid (CSF) as form of leukocytosis of blood and moderately increased cell count with elevated protein in CSF and blood in case of CTV. The authors noted an elevated protein in CSF and blood and leukocytosis with predominant lymphopenia in blood and neurophilic predominance in CSF within the reference range of CSF in patient with ischemic stroke. The epileptic attacks, meningeal syndromes, headaches were more often among clinical syndromes at CTV than in case of ischemic stroke. The algorithm of neuroimaging research methods and modes of MRI were determined and allowed an effective diagnostics of damages of venous sinuses, superficial and deep cerebral veins in case of urgent hospitalization of patients. It was possible to suggest the venous pathology in 7 (63,6%) cases due to SKT (without contrast) and in case of application of MR venography (2D TOFmode), there were revealed 100% of cases.

54 patients with acute stroke were examined and treated: 12 patients were treated by thrombolytic therapy and/or thrombectomy, 22 patients were treated by endarterectomy from the internal carotid artery, and 20 patients were treated by anticoagulant, nootropic and antiplatelet therapy. Collateral blood circulation of blood vessels and foci of cerebral ischemia in ischemic stroke were examined in all patients to select a treatment method. The effect of collateral circulation in patients with recanalization of the carotid and cerebral arteries on the outcome of acute stroke treatment was analyzed. According to such parameters of neuroimaging as a large nucleus and poor collaterals, 25 out of 54 patients did not respond to revascularizing therapy, which was proved by CT data and a slight regression of neurological deficit within 14 days. Patients with a large nucleus and poor collateral circulation do not respond to revascularization surgery. Compared groups of patients according to CT data. It was found that the level of development of collaterals was associated with better clinical results. Adequate collateral circulation can help maintain tissue viability in the absence of recanalization. The choice of revascularization method depends on the state of collateral circulation, the size of the ischemic focus (according to CT, MRI) and the duration of treatment from the onset of stroke. Diagnosis of ischemia should begin with MRI angiography on the first day or CT angiography from the second day, which will allow assessing the level of collaterals, giving an idea of collateral perfusion in patients and the size of the lesion.

Abstract Methods currently used in brain vascular disorder diagnostics are neither fast enough nor clear-out; thus, there exists a necessity of finding new types of testing which could enlarge and complete the actual panel of diagnostics or be an alternative to current methods. The discovery of sensitive and specific biomarkers of ischemic brain stroke will improve the effects of treatment and will help to assess the progress or complications of the disease. The relevant diagnosis of ischemic stroke (IS) within the first 4.5 hours after the initial symptoms allows for the initiation of treatment with recombinant tissue plasminogen activators which limits the magnitude of negative changes in the brain and which enhance the final effectiveness of therapy. The potential biomarkers which are under investigation are substances involved in the processes of coagulation and fibrinolysis, and are of molecules released from damaged vascular endothelial cells and from nerves and cardiac tissue. The analyzed substances are typical of oxidative stress, apoptosis, excitotoxicity and damage of the blood brain barrier.

Circadian biology modulates almost all aspects of mammalian physiology, disease, and response to therapies. Emerging data suggest that circadian biology may significantly affect the mechanisms of susceptibility, injury, recovery, and the response to therapy in stroke. In this review/perspective, we survey the accumulating literature and attempt to connect molecular, cellular, and physiological pathways in circadian biology to clinical consequences in stroke. Accounting for the complex and multifactorial effects of circadian rhythm may improve translational opportunities for stroke diagnostics and therapeutics.

ObjectivesTo clarify diagnostic accuracy and consequences of misdiagnosis in the admission evaluation of stroke-code patients in a neurologic emergency department with less than 20-minute door-to-thrombolysis times.MethodsAccuracy of admission diagnostics was studied in an observational cohort of 1,015 stroke-code patients arriving by ambulance as candidates for recanalization therapy between May 2013 and November 2015. Immediate admission evaluation was performed by a stroke neurologist or a neurology resident with dedicated stroke training, primarily utilizing CT-based imaging.ResultsThe rate of correct admission diagnosis was 91.1% (604/663) for acute cerebral ischemia (ischemic stroke/TIA), 99.2% (117/118) for hemorrhagic stroke, and 61.5% (144/234) for stroke mimics. Of the 150 (14.8%) misdiagnosed patients, 135 (90.0%) had no acute findings on initial imaging and 100 (67.6%) presented with NIH Stroke Scale score 0 to 2. Misdiagnosis altered medical management in 70 cases, including administration of unnecessary treatments (thrombolysis n = 13, other n = 24), omission of thrombolysis (n = 5), delays to specific treatments of stroke mimics (n = 13, median 56 [31–93] hours), and delays to antiplatelet medication (n = 14, median 1 [1–2] day). Misdiagnosis extended emergency department stay (median 6.6 [4.7–10.4] vs 5.8 [3.7–9.2] hours; p = 0.001) and led to unnecessary stroke unit stay (n = 10). Detailed review revealed 8 cases (0.8%) in which misdiagnosis was possible or likely to have worsened outcomes, but no death occurred as a result of misdiagnosis.ConclusionsOur findings support the safety of highly optimized door-to-needle times, built on thorough training in a large-volume, centralized stroke service with long-standing experience. Augmented imaging and front-loaded specialist engagement are warranted to further improve rapid stroke diagnostics.

Pregnancy-related ischemic strokes play an important role in both maternal and fetal morbidity and mortality. Changes in hemostaseology and hemodynamics as well as risk factors related to or independent from pregnancy contribute to the increased stroke-risk during gestation and the puerperium. Potential teratogenic effects make diagnostics, acute therapy and prevention challenging. Because randomized, controlled trials are not available, a multicenter registry of patients with gestational stroke would be desirable. Until definite guidelines emerge, management of acute ischemic stroke during pregnancy remains individual, involving experts and weighing the risks and benefits. Orv. Hetil., 2016, 157(20), 763–766.

The aim of this review is to systematize the currently accumulated knowledge on post-stroke periarthropathy, obtained as a result of various research studies of many years. The review shows the evidence that in modern world poststroke periarthropathy manifestation is increased in quantity, as well as discusses its consequences. Anatomical and biomechanical features of the shoulder joint are considered, together with pain syndrome mechanism and risk factors. Analysis of relation between age and complications development probability is performed. The focus is on currently developed set of treatment options. They include medication, physiotherapy, reflexology, manual treatment, as well as osteopathic treatment methods. At the moment, osteopathic treatment is an innovative and, thus, the least understood way of working with this problem. But the results achieved by now suggest that osteopathy can help many patients with stroke consequences. The conclusion is that post-stroke periarthropathy of the shoulder joint always requires a comprehensive treatment approach and an individual program is developed in each case.

Annotation:

The relationship of migraine and stroke has long been known. Migraine infarction is a rare complication of migraine and accounts for 0.2-0.5 % of all cases of ischemic strokes. This complication most often develops in women in the vertedro-basilary vascular system. Despite the widespread prevalence of migraine in the population, there is a tendency to underestimate the role of migraine in the development of cerebral infarction and, as a result, the lack of recommendations for the treatment and rehabilitation of this category of patients. The purpose of this article is to describe the clinical case of the diagnosis and rehabilitation of a patient with a migraine stroke. During rehabilitation of patients with migraine infarction, it is necessary to use, in addition to traditional rehabilitation methods: kinesiotherapy, exercise therapy, physiotherapy, rehabilitation methods aimed at preventing the development of migraine attacks, which improves the quality of life of this category of patients.

This paper focuses on the clinical and social diagnostics of stroke-like symptoms in Limpopo Province, South Africa. The research questions addressed here are: what are the lay understandings of strokelike symptoms and what are the health-seeking behaviours of Tsongan Mozambican refugees and South Africans in this area? The study site is ten villages in the Agincourt sub-district of Limpopo Province which are within the health surveillance area of the Agincourt Health and Population Unit (AHPU) of the University of Witwatersrand. The population are Tsongan who speak Shangaan and comprise self-settled Mozambican refugees who fled to this area during the 1980s across the nearby border and displaced South African citizens. The latter were forcibly displaced from their villages to make way for game reserves or agricultural development and moved to this area when it was the former ‘homeland’ of Gazankulu. The team collected data using rapid ethnographic assessment and household interviews as part of the Southern Africa Stroke Prevention Initiative (SASPI). The main findings are that stroke-like symptoms are considered to be both a physical and social condition, and in consequence plural healing using clinical and social diagnostics is sought to address both these dimensions. People with stroke-like symptoms maintain their physical, mental and social well-being and deal with this affliction and misfortune by visiting doctors, healers, prophets and churches.

This paper describes new methodologies and algorithms for use in engine diagnostics that simplify and improve combustion quality monitoring and closed-loop engine control in order to meet stringent emission standards. The “synthetic” variables these algorithms produce can be used to indicate the work produced by each cylinder combustion event at all engine speeds, and can be effectively used for on-board combustion quality measurements, engine diagnostics, and closed-loop control. The algorithms are very simple in form, run in real time, and the methodologies can be applied to compression ignition or spark ignition, 2-stroke or 4-stroke gasoline or diesel engines. Both simulation and experimental results are given for a two-stroke, two-cylinder in-line engine. The rotational dynamics and firing sequence of this configuration of engine is very similar to a four-stroke, four cylinder in-line engine, and nearly identical results will be seen with these two designs. Even more dramatic improvements can be seen with engines of fewer cylinders because of greater variations in their inertial forces. The algorithms can be successfully applied to many other engine configurations as well. Therefore, benefits can be derived from the application of these algorithms and their “synthetic” variables to control strategies for almost all modern small and medium size automotive and marine engines, as well as utility engines used for lawn care, snow removal, and other similar applications.

ZusammenfassungVorhofflimmern (VHF) ist ein wichtiger Risikofaktor für Schlaganfälle. Eine orale Antikoagulation kann das Auftreten von Schlaganfällen hocheffektiv verhindern, daher ist die Detektion von VHF besonders wichtig. Insbesondere paroxysmales VHF entgeht den üblichen diagnostischen Methoden häufig. Ein „Goldstandard“ zur VHF Detektion ist nach wie vor nicht etabliert. Grundsätzlich gilt: Je länger die EKG-Ableitung desto höher die zu erreichende Detektionsrate. Neben direkten Nachweisverfahren, existieren indirekte Verfahren wie die Analyse der Herzratenvariabilität und Modelle zur Vorhersage von VHF und zur Selektion von Patienten für erweiterte Detektionsmethoden. Diese sind allerdings bislang noch unzureichend untersucht und werden im Alltag kaum eingesetzt. Konnte VHF nach einem Schlaganfall bzw. einer TIA nachgewiesen werden, besteht eine Indikation für eine orale Antikoagulation. Im Falle positiver Studienergebnisse könnte das Indikationsspektrum einer oralen Antikoagulation in Zukunft auf Patienten mit „embolic stroke of undetermined source“ (ESUS) erweitert werden. Eine mögliche Alternative zur medikamentösen Schlaganfallprävention bei VHF stellt der interventionelle Vorhofohrverschluss dar.

Background Recent advances in treatment for stroke give new possibilities for optimizing outcomes. To deliver these prehospital care needs to become more efficient. Aim To develop a framework to support improved delivery of prehospital care. The recommendations are aimed at clinicians involved in prehospital and emergency health systems who will often not be stroke specialists but need clear guidance as to how to develop and deliver safe and effective care for acute stroke patients. Methods Building on the successful implementation program from the Global Resuscitation Alliance and the Resuscitation Academy, the Utstein methodology was used to define a generic chain of survival for Emergency Stroke Care by assembling international expertise in Stroke and Emergency Medical Services (EMS). Ten programs were identified for Acute Stroke Care to improve survival and outcomes, with recommendations for implementation of best practice. Conclusions Efficient prehospital systems for acute stroke will be improved through public awareness, optimized prehospital triage and timely diagnostics, and quick and equitable access to acute treatments. Documentation, use of metrics and transparency will help to build a culture of excellence and accountability.

ZusammenfassungDie Untersuchung der hirnversorgenden Arterien mittels Doppler- und Duplexsonografie war bislang fester Bestandteil des bewährten Stroke-Unit-Konzepts. Dies hat sich mit der Neufassung der Schlaganfall-OPS geändert: neurosonografische Untersuchungen während der Stroke-Unit-Behandlung sind im Falle der Durchführung einer CT- bzw. MR-Angiografie nicht mehr gefordert. Nach Eintritt eines ischämischen Schlaganfalls laufen im betroffenen Gefäßsegment und den dazugehörigen Kollateralwegen komplexe, individuell unterschiedliche, hämodynamische Umstellungsprozesse ab, die für das Schicksal des Patienten entscheidend sind. Verschlüsse können persistieren, partiell oder komplett rekanalisieren, kollateral kompensiert werden oder nach Rekanalisation wieder re-okkludieren. Diese Prozesse in den ersten Stunden können mittels Ultraschall wie mit keiner anderen Methode verfolgt werden. Je früher die Untersuchung erfolgt, desto aufschlussreicher sind die Befunde, desto besser ist das pathophysiologische Verständnis und desto größer ist der individuelle Nutzen für therapeutische Entscheidungen. Vielfach werden CTA, MRA und Ultraschall in der Schlaganfallversorgung als kompetitive Methoden begriffen. In Wahrheit handelt es sich aber um komplementäre Verfahren, mit denen auf der Basis von sehr unterschiedlichen physikalischen Prinzipien Bilder erzeugt und Blutgefäße, Hirnperfusion und Blutflüsse dargestellt werden. Mit Blick auf eine spezielle klinische Fragestellung ist jeweils das eine oder andere Verfahren indiziert. Es obliegt dem klinisch verantwortlichen Neurologen hier die richtige Auswahl zu treffen und spezifische neurosonologische Kompetenz einzubringen. Ziel dieser Übersichtsarbeit ist es, Neurologinnen und Neurologen dazu zu motivieren, Neurosonologie speziell in der Akutphase des Schlaganfalls einzusetzen um sich selbst ein Bild zu machen, anstatt sich „ein Bild machen zu lassen“.

Vascular cognitive impairment is closely related to stroke. Each condition is a risk factor for the other. Cognitive impairment is a symptom that makes it difficult for a stroke patient to live at home. In this review paper, different types of vascular cognitive impairment are discussed, with emphasis on cognitive impairment related to lacunar strokes (LACS). Symptoms, diagnostics, epidemiology, treatment, and prognosis are surveyed. LACS are often associated with leukoaraiosis, which is related to subcortical ischemic vascular dementia. Even if LACS often are mild, they may therefore be associated with cognitive impairment on longer term.

Comprehensive stroke care is an interdisciplinary challenge. Close collaboration of cardiologists and stroke physicians is critical to ensure optimum utilisation of short- and long-term care and preventive measures in patients with stroke. Risk factor management is an important strategy that requires cardiologic involvement for primary and secondary stroke prevention. Treatment of stroke generally is led by stroke physicians, yet cardiologists need to be integrated care providers in stroke units to address all cardiovascular aspects of acute stroke care, including arrhythmia management, blood pressure control, elevated levels of cardiac troponins, valvular disease/endocarditis, and the general management of cardiovascular comorbidities. Despite substantial progress in stroke research and clinical care has been achieved, relevant gaps in clinical evidence remain and cause uncertainties in best practice for treatment and prevention of stroke. The Cardiovascular Round Table of the European Society of Cardiology together with the European Society of Cardiology Council on Stroke in cooperation with the European Stroke Organisation and partners from related scientific societies, regulatory authorities and industry conveyed a two-day workshop to discuss current and emerging concepts and apparent gaps in stroke care, including risk factor management, acute diagnostics, treatments and complications, and operational/logistic issues for health care systems and integrated networks. Joint initiatives of cardiologists and stroke physicians are needed in research and clinical care to target unresolved interdisciplinary problems and to promote the best possible outcomes for patients with stroke.

Abstract Cardiologists need a better understanding of stroke and of cardiac implications in modern stroke management. Stroke is a leading disease in terms of mortality and disability in our society. Up to half of ischaemic strokes are directly related to cardiac and large artery diseases and cardiovascular risk factors are involved in most other strokes. Moreover, in an acute stroke direct central brain signals and a consecutive autonomic/vegetative imbalance may account for severe and life-threatening cardiovascular complications. The strong cerebro-cardiac link in acute stroke has recently been addressed as the stroke-heart syndrome that requires careful cardiovascular monitoring and immediate therapeutic measures. The regular involvement of cardiologic expertise in daily work on a stroke unit is therefore of high importance and a cornerstone of up-to-date comprehensive stroke care concepts. The main targets of the cardiologists’ contribution to acute stroke care can be categorized in three main areas (i) diagnostics workup of stroke aetiology, (ii) treatment and prevention of complications, and (iii) secondary prevention and sub-acute workup of cardiovascular comorbidity. All three aspects are by themselves highly relevant to support optimal acute management and to improve the short-term and long-term outcomes of patients. In this article, an overview is provided on these main targets of cardiologists’ contribution to acute stroke management.

Stroke is the second cause of death and more importantly first cause of disability in people over 40 years of age. Current therapeutic management of ischemic stroke does not provide fully satisfactory outcomes. Stroke management has significantly changed since the time when there were opened modern stroke units with early motor and speech rehabilitation in hospitals. In recent decades, researchers searched for biomarkers of ischemic stroke and neuroplasticity in order to determine effective diagnostics, prognostic assessment, and therapy. Complex background of events following ischemic episode hinders successful design of effective therapeutic strategies. So far, studies have proven that regeneration after stroke and recovery of lost functions may be assigned to neuronal plasticity understood as ability of brain to reorganize and rebuild as an effect of changed environmental conditions. As many neuronal processes influencing neuroplasticity depend on expression of particular genes and genetic diversity possibly influencing its effectiveness, knowledge on their mechanisms is necessary to understand this process. Epigenetic mechanisms occurring after stroke was briefly discussed in this paper including several mechanisms such as synaptic plasticity; neuro-, glio-, and angiogenesis processes; and growth of axon.

The running diagnostics of the combustion process in an internal combustion engine is essential for increasing its efficiency and to improving its performance indicators. The modern diagnostics of this process no longer concerns only measurements of fast-changing thermodynamic variables, but also measurements of other parameters allowing for its evaluation. The use of electrical or optical methods in diagnostics enables the evaluation of local process parameters, such as occurrence of the flame and its temperature distribution. Actually, there are some new methods under investigation which are proposed for this kind of diagnostic. This article focuses on demonstrating the potential for using an electric signal from the gas ionization to estimate the maximum combustion pressure in a cylinder of an SI engine. This is a comparative analysis of the gas ionization current signal in the cylinder and the fast-changing pressure at fixed operating points of a 4-stroke natural gas powered engine. The study was carried out on a one-cylinder 4-stroke SI engine equipped with a cylinder pressure recording system and monitoring of the cylinder ionization current using appropriate measuring systems. The influence of engine operating conditions on the ability to determine cylinder pressure based on the ionization current signal was analyzed. This impact assessment was analyzed statistically and a strong correlation was found between the analyzed signals. The obtained results point in the potential direction of development of this type of measuring system.
