Background Autonomic nervous system activity has been shown to be altered in patients with vasospastic angina (VA). Heart rate recovery (HRR) is a simple, non-invasive measurement of autonomic nervous system dysfunction. We aimed to investigate whether HRR is related to VA, as established by an ergonovine test. Methods A total of 976 consecutive patients (47.5% male, mean age 55 years) withou...

handgrip. There are other approaches for evaluating the autonomic nervous system by heart rate variability (HRV) parameters from shortor longterm monitoring (2). We agree that HRV and bedside autonomic function tests for evaluating the autonomic nervous system provide complementary information regarding autonomic regulatory mechanisms in health and disease. However, the bedside autonomic functi...

OBJECTIVE To gather current information about the effects of type 1 diabetes mellitus on children's cardiac autonomic behavior. DATA SOURCES The search of articles was conducted on PubMed, Ibecs, Medline, Cochrane, Lilacs, SciELO and PEDro databases using the MeSH terms: "autonomic nervous system", "diabetes mellitus", "child", "type 1 diabetes mellitus", "sympathetic nervous system" and "par...

BACKGROUND Many patients with acute coronary syndromes are offered percutaneous coronary intervention. However, the appropriate indications for, and optimal timing of, such procedures are uncertain. We analysed timing of intervention and associated events (death and myocardial infarction) in the PURSUIT trial in which 9461 patients received a platelet glycoprotein IIb/IIIa inhibitor, eptifibati...

conclusions an adjuvant therapy with tlc diet and supplementation with q10 and lc seems to be required for secondary prevention following mi and pci. tlc diet and q10 plus lc appeared to be effective in inflammatory biomarkers of isr as well as ldl reduction. methods this single-blind randomized controlled trial was conducted on 128 subjects. after randomization for treatment allocation, the su...

OBJECTIVE Low heart rate variability (HRV) has been confirmed in heroin users, but the effects of heart-rate-variability-biofeedback in heroin users remain unknown. This study examined (1) correlations between depression and HRV indices; (2) group differences in HRV indices among a heroin-user group, a group with major depressive disorder but no heroin use, and healthy controls; and (3) the eff...

cular disease. The HRR index, typically measured as a reduction in the heart rate (heart rate/min) in the first minute following the treadmill exercise test and presenting an altered balance within the autonomic nervous system, has drawn increasing attention as an important prognostic marker of cardiovascular status [4, 5]. So, Sarli et al. [1] presented for the first time in the literature tha...
