We aimed to investigate whether bright light (BL) exposure affects sympathovagal activity in controlling heart rate (HR) before and after exercise. Eighteen healthy men (28 ± 4 years) underwent two experimental conditions: one under BL (5000 lux) and another under dim light (DL < 8 lux). In both conditions, subjects performed an aerobic exercise bout (cycle ergometer, 30 min at 50-60% of HRreserve).

Objectives: To clarify the role of hippocampal glutamate system in regulating HPA axis in mediating the effect of electroacupuncture (EA) at the heart meridian for improving myocardial injury in rats with acute myocardial ischemia (AMI).
Methods: Male SD rats were randomized into sham-operated group, AMI group, EA group, and L-glutamic acid+EA group (=9). Rat models of AMI were established by left descending coronary artery ligation, and EA was applied at the "Shenmen-Tongli" segment; the rats in L-glutamic acid+EA group were subjected to microinjection of L-glutamic acid into the bilateral hippocampus prior to AMI modeling and EA treatment.

The QT interval is a key indicator in assessing arrhythmia risk, evaluating drug safety, and supporting clinical diagnosis in cardiology. The QT interval is significantly influenced by heart rate so it must be accurately corrected to ensure reliable clinical interpretation. Conventional correction formulas, such as Bazett's formula, are widely utilized but often criticized for inaccuracies, either under- or overcorrecting QT intervals in different physiological conditions.

Background: Migraine is associated with an increased cardiovascular risk, including hypertension. Anti-calcitonin gene related peptide (CGRP) monoclonal antibodies (mAbs) are effective preventive treatments, but concerns have been raised about their potential hypertensive effects. Herein, we assess the early changes in blood pressure (BP) during anti-CGRP mAbs treatment in patients with migraine using 24-h Holter monitoring.
