Physiological Resilience: A New Pillar of Endurance Exercise Performance (Part I of II)

Physiologically Speaking

Endurance performance is determined by three primary variables which were proposed by Dr. Michael Joyner over 3 decades ago in a paper titled “Modeling optimal marathon performance on the basis of physiological factors.” These factors are the performance VO2, lactate threshold, and running economy. Performance VO2 is the average oxygen consumption an athlete has to sustain during an event, e.g., the marathon.

Dynamic Coronary Roadmap Reduces Contrast Use in Percutaneous Coronary Interventions

Cardiology Update

Minimizing iodinated contrast use stands as a critical safety measure in percutaneous coronary interventions (PCI), especially for patients at heightened risk of contrast-induced acute kidney injury (CI-AKI). Dynamic Coronary Roadmap (DCR) serves as a PCI navigation aid by projecting a motion-compensated virtual coronary roadmap overlay onto fluoroscopy, potentially diminishing the necessity for contrast during PCI.

Link between high levels of niacin -- a common b vitamin -- and heart disease, study suggests

Science Daily - Heart Disease

Researchers have identified a new pathway that contributes to cardiovascular disease associated with high levels of niacin, a common B vitamin previously recommended to lower cholesterol. The team discovered a link between 4PY, a breakdown product from excess niacin, and heart disease. Higher circulating levels of 4PY were strongly associated with development of heart attack, stroke and other adverse cardiac events in large-scale clinical studies.
