Summary
Single-centre prospective study to characterize causes of dyspnea in stable patients with coronary artery disease and evaluate the possibility to determine the cause of dyspnea before in-depth examination.
Detailed description
Stable patients with dyspnea and coronary artery disease will be included in this single-centre prospective study. In addition to routine clinical examination patients will be interviewed to determine the nature of shortness of breath, angina, presence of chronic heart failure or anxiety using the Medical Research Council Dyspnea scale, the visual analog scale of dyspnea, Borg scale, modified "dictionary" of dyspnea, G. Rose questionnaire, Seattle Angina Questionnaire, Framingham criteria for chronic heart failure and the SHOCK scale. During the subsequent in-depth examination including thyroid hormones, NT-proBNP, hsTroponin, ECG monitoring, six-minute walk test, stress-echo with a diastolic stress test, spirometry and coronary angiography (if necessary) main reason for dyspnea will be established. Possibilities of early (before in-depth examination) determination the reason for dyspnea in stable patients with coronary artery disease will be evaluated.
