Obesity and heart rate variability in men with myocardial infarction.
BACKGROUND Obesity has been shown to affect heart rate variability (HRV). Adipokines (hormone-like peptides secreted by adipose tissue) display several bioactivities and have an impact on the cardiovascular system. The aim of the study was to evaluate the impact of obesity (BMI > or = 30) and adipokines (leptin, adiponectin and resistin) on HRV. METHODS In 43 obese and 38 non-obese males with...
متن کاملHeart rate variability during the acute phase of myocardial infarction.
BACKGROUND After acute myocardial infarction (AMI), several abnormalities of the autonomic control to the heart have been described. Heart rate (HR) variability has been used to explore the neural control to the heart. A low HR variability count measured 7-13 days after AMI is significantly related to a poor outcome. Little information is available on HR variability early after AMI and its rela...
متن کاملDepression, heart rate variability, and acute myocardial infarction.
BACKGROUND Clinical depression is associated with an increased risk for mortality in patients with a recent myocardial infarction (MI). Reduced heart rate variability (HRV) has been suggested as a possible explanation for this association. The purpose of this study was to determine if depression is associated with reduced HRV in patients with a recent MI. METHODS AND RESULTS Three hundred eig...
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: A PREDICTOR OF EARLY MORTALITY IN PATIENTS WITH MYOCARDIAL INFARCTION
A number of epidemiologic studies have reported a positive relationship between heart rate, cardiovascular disease and mortality. To examine the correlation between heart rate and mortality after acute myocardial infarction (AMI), 2147 patients hospitalized in coronary care units in Isfahan were investigated in a cross-sectional study. Their heart rate was measured according to an electroca...
