Time-Domain Heart Rate Variability in Coronary Artery Disease Patients Affected by Thyroid Dysfunction

Is Subclinical Thyroid Dysfunction Associated With with Coronary Heart Disease?

Introduction: Previous cohort studies reported contradictory data on the association between subclinical thyroid dysfunction and coronary heart disease (CHD). Regarding this, the present study was conducted to illuminate this relationship. Materials and Methods: For the purpose of the study, 3,066 participants employed in a study conducted by Azizi et al. aged ≥ 20 years were subjected to thyro...

Evaluation of heart rate variability in patients with coronary artery ectasia and coronary artery disease.

OBJECTIVE The present study compared heart rate variability (HRV) parameters in patients with coronary artery ectasia (CAE) and coronary artery disease (CAD). METHODS The study population consisted of 60 consecutive patients with CAE (14 women; mean age 51.63±7.44 years), 60 consecutive patients with CA (15 women; mean age 53.67±9.31 years), and 59 healthy individuals (13 women; mean age 52.8...

Reduction in Heart Rate Variability with Traffic and Air Pollution in Patients with Coronary Artery Disease

INTRODUCTION Ambient particulate pollution and traffic have been linked to myocardial infarction and cardiac death risk. Possible mechanisms include autonomic cardiac dysfunction. METHODS In a repeated-measures study of 46 patients 43-75 years of age, we investigated associations of central-site ambient particulate pollution, including black carbon (BC) (a marker for regional and local traffi...

Heart Rate in Patients with Coronary Artery Disease in Latvia

Heart rate variability in coronary artery disease patients with and without panic disorder.

Panic disorder (PD) and coronary artery disease (CAD) often co-occur, and CAD patients with comorbid PD suffer greater cardiovascular morbidity and mortality relative to CAD patients without PD. However, the mechanisms underlying these associations are still unknown. Reduced heart rate variability (HRV), a non-invasive measure of cardiac autonomic modulation, is an important predictor of advers...
