Meta-heuristic algorithms for feature selection in classification of heart-related diseases
Švestková, Tereza ; Odstrčilík, Jan (referee) ; Mézl, Martin (advisor)
This thesis is devoted to the features selection for classification tasks related to heart disease. The optimal features selection is a key factor for the correct functionality of classification models and, in the case of medicine, for the improvement of diagnostics. The theoretical part discusses the general classification task in machine learning. Furthermore, some classic procedures as well as newer meta-heuristic algorithms for efficient feature selection are described in more detail. The practical part is devoted to the application of some of the described algorithms to data sets related to heart disease. The advantages and benefits of prioritizing meta-heuristic algorithms are discussed based on the verification of the validity of the result of the classification model according to selected symptoms of common procedures and evolutionary algorithms.

Cardiac surgery from the patient's point of view
Kracíková, Nikola ; Gigalová, Veronika (advisor) ; Vlášková, Dana (referee)
Autor: Nikola Kracíková Institution: Charles University in Prague Faculty of Medicine in Hradec Kralove, Department of Social Medicine Division of Nursing Title: Cardiac surgery from the patient's point of view Supervisor: Mgr. Veronika Gigalová Number of pages: 154 Number of attachments: 4 Year of defense: 2019 Keywords: Cardiac-surgery patient, heart disease, sensation, fear The bachelor's thesis deals with the subjective perception of cardiac surgery patients, being hospitalized in the standard department of the Cardiac Surgery Clinic of the University Hospital Hradec Králové, on their cardiac surgery. The thesis is divided into two parts, the theoretical and empirical. The theoretical part describes the general history and present state of cardiosurgery, possible indications leading to cardiac surgery, the selection of surgical approaches and the patient's standard preoperative and postoperative care proces. The theoretical part is also focused on the subjective perception on the illness, the individuality and diagnosis of the subjective perception of the illness and also theoretical approaches leading to the assessment of the patient's disease. The empirical part focuses on a questionnaire survey based on the patient's subjective experience of the heart disease and this part is supplemented...

Nursing care for a child with heart disease at the intensive care unit
SMEJKALOVÁ, Jitka
Children heart diseases can be divided into congenital and acquired heart defects. The acquired heart defects can be further divided into acquired heart defects, heart rhythm disorders, including hypertension, inflammatory heart diseases and heart failure. Children heart diseases can occur at any age, even if it is a congenital heart defect that is less severe. The goal of this thesis was to find out the specifics of nursing care of children with heart diseases who are hospitalized at ICU and to find out the most common nursing diagnoses according to NANDA II taxonomy, and their treatment in case of children with heart diseases who are hospitalized at ICU. During the realization of the research part, a qualitative research survey was conducted using semi-structured interviews with the nurses, participant observation and the method of content analysis, which provide a more complex view of the composition of the children with heart disease hospitalized at ICU. The interviews were conducted with the nurses at the children's ICU, where the participant observation and the method of content analysis took place as well. The results of the research show that nursing care differs in the case of cardiologic disordered children and otherwise disordered children in some areas, as well as the needs. In the research part it was found out what the most frequent nursing interventions in case of these children are and how much they differ from the interventions of children with other diseases, who are also hospitalized at ICU. Furthermore, the research shows that nurses have a negative opinion on nursing diagnoses, although they are used in the documentation. This was found not only in the semi-structured interviews with the nurses, but also during the participated observation and the content analysis of the documentation. The research also revealed that some nursing diagnoses are specific to cardiologic disordered children, but, for example, the nursing diagnosis of the risk of infection associated with invasive entry is used in case of all children hospitalized at ICU. The diploma thesis should inform nurses about nursing care in case of children with heart disease hospitalized at ICU.

Children heart diseases can be divided into congenital and acquired heart defects. The acquired heart defects can be further divided into acquired heart defects, heart rhythm disorders, including hypertension, inflammatory heart diseases and heart failure. Children heart diseases can occur at any age, even if it is a congenital heart defect that is less severe. The diploma thesis should bring nurses closer to the problems of nursing care of children with heart diseases hospitalized at the ICU. The goal of this thesis was to find out the specifics of nursing care of children with heart diseases who are hospitalized at the ICU and to find out the most common nursing diagnoses according to NANDA II taxonomy, and their treatment in case of children with heart diseases who are hospitalized at the ICU. During the realization of the research part, a qualitative research survey was used using semi-structured interviews with the nurses involved in the observation. And a summarization that provides a more comprehensive view of the composition of children with heart diseases hospitalized at the ICU. The interviews were conducted with the nurses at the children's ICU, where the participant observation took place as well. In the research section the most common nursing interventions in case of these children were described and how much they differ from interventions in case of children with other illnesses that are also hospitalized at the ICU. Further, we have also found out the most common nursing diagnoses of children with heart diseases hospitalized at the ICU.

Care for patient with chronic heart failure
FORMÁNKOVÁ, Hana
The bachelor thesis refers to the aspects of the nursing care for patients with chronic heart failure. The aim of the thesis is to identify the specifics of the nursing care for patients with chronic heart failure. Furthermore, the subsequent aim is to identify the most frequent nursing problems with patients with chronic heart failure. The qualitative research inquiries were used to reach the defined aims. Semi-structured conversation with patients suffering with chronic heart failure and with nurses working at cardiology intermediary care and the ambulance of heart failure was the most used method to collect the data. Interesting results were achieved with the research. Respondents had a limited knowledge about the classification according to NYHA, but the knowledge of diseases was at a good level. Nurses and even patients agreed on regimes measures, which were implemented upon patients with chronic heart failure at the emergency and at the department. There were some references to Fowler positions, ECG, blood collection and following checkup. Nurses added further professional information, but they coincided with patients. Patients bore the best knowledge of the regime measures. The efficiency of education of nurses about the regimes measures has been reflected in responses of respondent patients. Patients knew which measures are related to their disease, what they should change and what they should start to do. Based on the answers, it can be stated that measures like sinking kitchen salt, restricting of intake liquids and No smoking are getting the overbearing role within regimes. An information booklet, which can serve for medical staff, for student of medical branches or for patients with chronic heart failure was created as an outcome of the Bachelor Thesis. In booklet they can find: what is it chronic heart failure, what causes it, what symptoms the disease has, classification according to NYHA, what is the prevention of the disease, pharmacotherapy, regimes and dietary measures, procedure upon acceptance patients to hospitalization, and further information.
