Depressed heart rate variability has independent prognostic value in patients with chronic heart failure; spectral analysis identifies an increased risk for sudden death in these patients.

The PETALE study will contribute to comprehensively characterize clinical, psychosocial, biologic, and genomic features of cALL survivors using an integrated approach. Expected outcomes include LAE early detection biomarkers, long-term follow-up guidelines, and recommendations for physicians and health professionals.

Preterm birth incurs an increased risk of early cardiovascular events and death. In the general population, cardiovascular risk factors cluster in the context of inflammation and oxidative stress. Whether this also occurs in young adults born preterm is unknown. We analyzed 101 healthy young adults (ages 18–29) born preterm (≤29 weeks of gestation) and 105 full-term controls, predominantly (90%) white. They underwent a comprehensive clinical and biological evaluation, including measurement of blood pressure, lung function (spirometry), glucose metabolism (fasting glucose, glycated hemoglobin, and oral glucose tolerance test), as well as biomarkers of inflammation and oxidative stress. Individuals born preterm were at higher risk than those born full-term of stage ≥1 hypertension (adjusted odds ratio, 2.91 [95% CI, 1.51–5.75]), glucose intolerance (adjusted odds ratio, 2.22 [95% CI, 1.13–4.48]), and airflow limitation (adjusted odds ratio, 3.47 [95% CI, 1.76–7.12]). Hypertension was strongly associated with adiposity and with glucose intolerance in participants born full-term but not in those born preterm. We did not find any group difference in levels of biomarkers of inflammation and oxidative stress. In individuals born preterm, inflammation, and oxidative stress were not related to hypertension or glucose intolerance but were associated with adiposity. In those born preterm, cardiovascular risk factors were not related to each other suggesting different pathophysiological pathways leading to the development of cardiovascular risk following preterm birth. Clinicians should consider screening for these abnormalities irrespectively of other risk factors in this at-risk population. Clinical Trial Registration URL: http://www.clinicaltrials.gov .

Remote ischemic preconditioning (RIPC) provides a substantial benefit for heart protection during surgery. Recent literature on RIPC reveals the potential to benefit the enhancement of sports performance as well. The aim of this study was to investigate the effect of RIPC on anaerobic performance. Seventeen healthy participants who practice regular physical activity participated in the project (9 women and 8 men, mean age 28 ± 8 years). The participants were randomly assigned to an RIPC intervention (four 5-minute cycles of ischemia reperfusion, followed by 5 minutes using a pressure cuff) or a SHAM intervention in a crossover design. After the intervention, the participants were tested for alactic anaerobic performance (6 seconds of effort) followed by a Wingate test (lactic system) on an electromagnetic cycle ergometer. The following parameters were evaluated: average power, peak power, the scale of perceived exertion, fatigue index (in watt per second), peak power (in Watt), time to reach peak power (in seconds), minimum power (in Watt), the average power-to-weight ratio (in watt per kilogram), and the maximum power-to-weight ratio (in watt per kilogram). The peak power for the Wingate test is 794 W for RIPC and 777 W for the control group (p = 0.208). The average power is 529 W (RIPC) vs. 520 W for controls (p = 0.079). Perceived effort for RIPC is 9/10 on the Borg scale vs. 10/10 for the control group (p = 0.123). Remote ischemic preconditioning does not offer any significant benefits for anaerobic performance.
