THE ROLE OF AMBULATORY CARDIAC REHABILITATION IN IMPROVEMENT OF QUALITY OF LIFE, ANXIETY AND DEPRESSION

Background: Psychological reactions may adversely affect recovery after major cardiac events. This study investigates the role and frequently negligible importance of ambulatory cardiac rehabilitation (ACR) in improvement of quality of life (QoL), anxiety and depression at patients with various cardiac pathology. Subjects and methods: This prospective study included subjects treated for acute coronary syndrome (ACS), those with performed elective revascularization, and OTHERS (after valve replacement, implanted pacemaker or other device, with stable heart failure and coronary artery disease). Their anxiety (State Trait Anxiety Inventory (STAI) questionnaire), depression (Beck Depression Inventory (BDI-II) questionnaire) and QoL data (Short Form Health Survey-36 (SF-36) questionnaire, for physical and mental QoL components) were collected initially and after 3-month of ACR. Results: ACR underwent 170 patients, aged 59 (53-66 years), predominately males (74.7%). At both genders, median duration of ACR was 12 weeks, with reduction of anxiety and depression scores and improvement in almost all components of QoL (P<0.05), except in mental health and bodily pain in males and females, respectively. After ACS (63.5%), ACR lasted 12 weeks, with reduction of anxiety and depression scores and improvement in all components of QoL (P<0.05). After elective revascularization (14.1%), ACR lasted 12 weeks, with reduction of anxiety score and improvement in almost all components of QoL (P<0.05), except mental health. At OTHERS (22.4%), ACR lasted 4 weeks, with improvement in almost all components of QoL (P<0.05), except mental health; ACR duration negatively correlated with anxiety and depressive scores (P<0.05). Conclusion: ACR during 3-month results with improvement of anxiety, depression and QoL at patients with various cardiac pathology

Heart failure ontology

Abstract Ontology represents explicit specification of knowledge in a specific domain of interest in the form of concepts and relations among them. This paper presents a medical ontology describing the domain of heart failure (HF). Construction of ontology for a domain like HF is recognized as an important step in systematization of existing medical knowledge. The main virtue of ontology is that the represented knowledge is both computer and humanreadable. The current development of the HF ontology is one of the main results of the EU Heartfaid project. The ontology has been implemented using Ontology Web Language and Protégé editing tool. It consists of roughly 200 classes, 100 relations and 2000 instances. The ontology is a precise, voluminous, portable, and upgradable representation of the HF domain. It is also a useful framework for building knowledge based systems in the HF domain, as well as for unambiguous communication between professionals. In the process of developing the HF ontology there have been significant technical and medical dilemmas. The current result should not be treated as the ultimate solution but as a starting point that will stimulate further research and development activities that can be very relevant for both intelligent computer systems and precise communication of medical knowledge

New philosophy of validation and verification for cardiology: classical proof theory imported from natural sciences

Aims Problems of validation and verification are very critical in medicine. The absence of adequate models describing biophysical processes in the organism leads to using only practical evidence for these purposes that hinders innovations. But advances in medicine require new effective ways to solve these problems. Cardiometry as a new field in cardiology offers a new philosophy of validation and verification based on the classical proof theory borrowed from natural sciences. The aim hereof is to provide a new methodology for validation and verification for cardiovascular diagnostics. Materials and methods Axiomatic concepts based on new laws and rules allow applying direct and indirect methods of proof for validation and verification in medicine. Results The formulated laws of cardiometry provide reliable tools for verification of the correspondence between the cardiac signals and the real biophysical processes in the cardiovascular system. Conclusion The proposed methodology for verification of the correspondence between the ECG shapes and the relevant biophysical processes has been successfully developed exclusively as a result of creation of the comprehensive theory of cardiac cycle phase analysis being the basis of cardiometry. Progress in cardiology is badly affected by the absence of an adequate cardiac cycle phase concept so that a lot of inconsistencies have been accumulated therein. It has been just the logics imported to the theoretical analysis methods of cardiology and supported by a new knowledge of the cardiac cycle phase structure that allows us to originally apply the natural science proof philosophy to cardiology
