A mental arithmetic task was administered to 39 subjects under conditions which imposed social stress. Using the relaxed state to provide a baseline, changes in heart rate and finger blood volume pulse were recorded. The subjects were divided to obtain groups with extreme scores on Eysenck's PEN...
TREADMILL STRESS TEST. THE ONLY CONCERN I HAVE IS THAT THIS TEST WAS RECOMMENDED BY MY HEART DOCTOR AFTER I HAD TAKEN A CARDIAC CT ANGIOGRAPHY WHICH INDICATED CALCIUM SCORES OF WHICH THE HIGHEST WAS 863. THIS WAS NOTICED IN THE LEFT INTERIOR DECENDING ARTERY WHICH WAS THE SAME ONE I HAD...
Patients with uncertain antenatal fetal monitoring had significantly more late decelerations during labor as well as newborns with low Apgar scores when compared to those with normal antenatal monitoring. Patients with abnormal antenatal monitoring (positive stress test) had significantly more low 5-min ...
Clinical scores estimating the likelihood of a HFpEF diagnosis. Full size image Fig. 3 Modified from Verwerft et al. [8] CAD, coronary artery disease; CMR, cardiac magnetic resonance imaging; CPET, cardiopulmonary exercise test; CT, computed tomography; ECG, electrocardiogram; PVI, pulmonary vei...
In the PPG dataset, their approach obtains an overall leave-one-participant-out F1-score of 80%, while the ground truth ECG scores 79.7%. Koldijk et al. [102] used the SWELL-KW dataset (149 features and 2688 instances in total) and compared SVM (accuracy: 90.0298%) with 7 other ...
This finding is echoed in Ky et al.’s work with multi-institute studies of HF patients, which resulted in improving risk discrimination scores by 14.9% after incorporation of sST2 into the Seattle HF Model for prediction of adverse outcomes [75]. Bayes-Genis et al. confirmed the results, ...
, we’ll explore what heart rate variability is, its relationship with your autonomic nervous system, the causes of low and high HRV scores and how to improve them, and how to track your HRV with Polar Nightly Recharge™, and how to use an HRV monitor to perform an Orthostatic Test....
mean diffusivity,P= 0.029 andP= 0.032, respectively). Low CFR was associated with higher resistive (P= 0.027) and pulsatility (P= 0.043) values on TCD, and worse neurocognitive test scores (lower Mini-Mental State E...
People with higher nPRS scores were also more likely to experience anxiety and depression. The researchers found that having anxiety or depression accounted for nearly one-quarter of the linkage between nPRS score and stress-triggered ACS. People with above median nPRS who also developed anxiety or...
We found statistically significant treatment group differences in depression and social support scores after the 6-month intervention period, but the magnitude of the effect may not have been sufficient to influence medical morbidity or mortality. The decline in HRSD scores for depressed patients in th...
