Heart rate variability and heart rate turbulence in patients with chronic obstructive pulmonary disease.
BACKGROUND In chronic obstructive pulmonary disease (COPD) patients, functional and structural changes of the respiratory system greatly influence cardiovascular autonomic functions. Determining autonomic balance may be important in understanding the pathophysiology of COPD and useful clinically in the treatment of COPD patients. Heart rate variability (HRV) and heart rate turbulence (HRT) are ...
متن کاملDo we need clinical trials to test the ability of transdermal HRT to prevent coronary heart disease?
Postmenopausal hormone replacement therapy (HRT) with oral oestrogen was predicted to reduce coronary heart disease (CHD) risk by 50%. Randomized controlled trials show no such benefit, however, pointing instead to an initial increase in CHD events. Although the cardiovascular effects of transdermal HRT are largely unknown, improvements in arterial function are maintained when oestrogen is admi...
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 کاملCardiovascular Risk During the Menopause
Although initial experimental data and results of observational studies suggest that hormone replacement therapy (HRT) is associated with a reduction in the risk of heart disease, the results for events such as stroke or thromboembolism are less clear. Randomized secondary and primary prevention studies have found that HRT is not protective against the risk of coronary heart disease, stroke or ...
متن کاملHeart rate turbulence: standards of measurement, physiological interpretation, and clinical use: International Society for Holter and Noninvasive Electrophysiology Consensus.
This consensus statement has been compiled on behalf of the International Society for Holter and Noninvasive Electrophysiology. It reviews the topic of heart rate turbulence (HRT) and concentrates on technologies for measurement, physiologic background and interpretation, and clinical use of HRT. It also lists suggestions for future research. The phenomenon of HRT refers to sinus rhythm cycle-l...
متن کاملHormone replacement therapy: prothrombotic vs. protective effects.
Hormone replacement therapy (HRT) is associated with reduced risk of coronary heart disease (CHD) and stroke in observational studies; however the possibility of confounding by other risk factors requires prospective assessment of its risks and benefits in randomised controlled trials. The HERS trial of oral HRT in secondary CHD prevention observed an early increased risk of myocardial infarcti...
