Background: Ambient air pollution is a major risk factor for CVDs, and a plausible mechanism is speculated to be alteration of autonomic nervous system (ANS) function. Yet, the short-term effects of air pollution on heart rate variability (HRV), a measure of ANS balance are inconsistent.Objective: This study aimed to evaluate the short-term effects of ambient… Continue reading Short-term association between ambient air #pollution and #heart #rate variability: results from the population-based KORA S4 and FF4 studies

Recovery #sleep following sleep restriction is insufficient to return elevated daytime heart #rate and systolic blood #pressure to baseline levels
Objective Sleep restriction alters daytime cardiac activity, including elevating heart rate (HR) and blood pressure (BP). There is minimal research on the cumulative effects of sleep loss and the response after subsequent recovery sleep on HR and BP. This study examined patterns of HR and BP across baseline, sleep restriction, and recovery conditions using multiple daytime cardiac… Continue reading Recovery #sleep following sleep restriction is insufficient to return elevated daytime heart #rate and systolic blood #pressure to baseline levels
Association of resting heart rate with cognitive decline and dementia in older adults: A population-based cohort study
Resting heart rate (RHR) predicts future risk for cardiovascular disease (CVD). However, longitudinal studies investigating the relationship of RHR with cognitive decline are scarce. Methods: This population-based cohort study included 2147 participants (age≥60) in SNAC-K who were free of dementia and regularly followed from 2001–2004 to 2013–2016. RHR was assessed with electrocardiogram. Dementia was diagnosed… Continue reading Association of resting heart rate with cognitive decline and dementia in older adults: A population-based cohort study
Temporal Changes in Resting #Heart Rate, Left Ventricular Dysfunction, Heart #Failure and Cardiovascular Disease: CARDIA Study
..Higher alcohol consumption (β=0.03, p<0.001), lower physical activity (β=0.002,p=001), smoking (β=1.58, p<0.001), men (p<0.001), African-Americans (p<0.001), impaired left ventricular relaxation (e´,β=-0.13, p=0.002), and worse diastolic function (E/e´,β=0.1, p=0.01) were associated with longitudinal increases in resting heart rate. We observed 268 cardiovascular disease and 74 heart failure events over a median of 26 years. In Cox… Continue reading Temporal Changes in Resting #Heart Rate, Left Ventricular Dysfunction, Heart #Failure and Cardiovascular Disease: CARDIA Study
#Exercise capacity and #body mass index – important predictors of change in resting #heart rate
Resting heart rate (RHR) is an obtainable, inexpensive, non-invasive test, readily available on any medical document. RHR has been established as a risk factor for cardiovascular morbidity, is related to other cardiovascular risk factors, and may possibly predict them. Change in RHR over time (∆RHR) has been found to be a potential predictor of mortality..… Continue reading #Exercise capacity and #body mass index – important predictors of change in resting #heart rate
