One of the most promising biomarkers of biological age are so-called DNA methylation-based age estimators, otherwise known as DNA methylation age clocks. Physical fitness was measured using VO2 peak obtained during a maximal exercise test (the gold standard way to measure this outcome). What can’t we infer from this study?

In our study, NT-proBNP provided little value in those with AF and dyspnea because the presence of AF is by itself a robust biomarker of HFpEF. Use of separate rule-in and rule-out diagnostic thresholds stratified by BMI reduces miscategorization and can guide more appropriate use of exercise testing for possible HFpEF.

Within exercise and sports science, no one measure has gotten more attention than VO2 max. VO2 max refers to your maximum rate of oxygen consumption, and it’s typically measured during a maximal exercise test to exhaustion (they’re not fun, trust me).

Decline in exercise ability is a hallmark of progression to overt heart failure. The international ARISE-HF trial was designed to test the effectiveness of the investigational drug AT-001 at stabilizing exercise capacity in patients with diabetic cardiomyopathy. Patients had had Type 2 diabetes for an average of 14 years.

4 Many environmental and lifestyle factors can throw our circadian system out of whack, which is why being prudent about sleep, diet, and exercise are crucial. The most common stimulus is an increase in blood flow (due to exercise), which elevates the production of nitric oxide (NO) and leads to the dilation (widening) of the artery diameter.
