Risk stratification after acute myocardial infarction by heart rate turbulence.
BACKGROUND Retrospective postinfarction studies revealed that decreased heart rate turbulence (HRT) indicates increased risk for subsequent death. This is the first prospective study to validate HRT in a large cohort of the reperfusion era. METHODS AND RESULTS One thousand four hundred fifty-five survivors of an acute myocardial infarction (age <76 years) in sinus rhythm were enrolled. HRT on...
متن کاملClinical Application of Heart Rate Variability after Acute Myocardial Infarction
Heart rate (HR) variability has been extensively studied in patients surviving an acute myocardial infarction (AMI). The majority of studies have shown that patients with reduced or abnormal HR variability/turbulence have an increased risk of mortality within few years after an AMI. Various measures of HR dynamics, such as time-domain, spectral, and non-linear measures of HR variability, as wel...
متن کاملHeart Rate Turbulence as Risk-Predictor after Myocardial Infarction
Heart rate turbulence (HRT) is the baroreflex-mediated short-term oscillation of cardiac cycle lengths after spontaneous ventricular premature complexes. HRT is composed of a brief heart rate acceleration followed by a gradual heart rate deceleration. In high risk patients after myocardial infarction (MI) HRT is blunted or diminished. Since its first description in 1999 HRT emerged as one of th...
متن کاملEffect of Cardiac Rehabilitation on Heart Rate and Functional Capacity in Patients After Myocardial Infarction
Objectives: The primary purpose of this study was to determine the methods and means of prevention and treatment of coronary artery disease. In this study, we used a new regimen on heart rate and functional capacity of patients after myocardial infarction. This study also determines the effect of a new regimen on these factors. Methods: The cross sectional study was designed to assess the clin...
متن کاملHeart Rate Variability Analysis in Risk of Asthma Stratification
Early diagnosis of asthma is crucial to avoid longterm effects such as permanent airway obstruction. Pathogenesis of asthma has been related with autonomic nervous system (ANS) dysfunction, concretely with abnormal parasympathetic activity. As heart rate variability (HRV) analysis does reflect ANS activity, it has been employed here in risk of asthma stratification.
