Heart rate dynamics in patients with stable angina pectoris and utility of fractal and complexity measures.
Dynamic analysis techniques may uncover abnormalities in heart rate (HR) behavior that are not easily detectable with conventional statistical measures. However, the applicability of these new methods for detecting possible abnormalities in HR behavior in various cardiovascular disorders is not well established. Conventional measures of HR variability were compared with short-term (< or = 11 be...
متن کامل[Studies of arrhythmia incidence and heart rate variability in patients with stable angina pectoris].
Continuous Holter ECG monitoring is a valuable, easy to perform, non-invasive method of assessing not only cardiac arrhythmias but also heart rate variability and autonomic nervous system function. The aim of the study was to determine cardiac arrhythmias and HRV in patients with stable angina with and without previous myocardial infarction. 156 patients, 92 with and 64 without previous myocard...
متن کاملAltered heart rate variability depend on the characteristics of coronary lesions in stable angina pectoris
OBJECTIVE Dysfunction of cardiac autonomic nerve system is considered as one of risk factors for coronary atherosclerotic heart disease. Heart rate variability (HRV) has been used to study the correlation between damage of coronary artery and dysfunction of autonomic nervous system. We hypothesize the correlation between damage of coronary artery and dysfunction of autonomic nervous system by H...
متن کاملPredicting prognosis in stable angina--results from the Euro heart survey of stable angina: prospective observational study.
OBJECTIVES To investigate the prognosis associated with stable angina in a contemporary population as seen in clinical practice, to identify the key prognostic features, and from this to construct a simple score to assist risk prediction. DESIGN Prospective observational cohort study. SETTING Pan-European survey in 156 outpatient cardiology clinics. PARTICIPANTS 3031 patients were include...
متن کاملSensitivity, specificity and predictive values of linear and nonlinear indices of heart rate variability in stable angina patients
UNLABELLED BACKGROUND Decreased heart rate variability (HRV) is related to higher morbidity and mortality. In this study we evaluated the linear and nonlinear indices of the HRV in stable angina patients submitted to coronary angiography. METHODS We studied 77 unselected patients for elective coronary angiography, which were divided into two groups: coronary artery disease (CAD) and non-CA...
