Article Synopsis
- Remote ischemic periconditioning (RIPC) enhances cardioprotection and outcomes during urgent procedures in STEMI patients but its effects on cardiac sympathetic nerve activity were unclear.
- The study involved assigning STEMI patients to either RIPC or a control group during emergency PCI, measuring cardiac nerve activity via I-MIBG imaging.
- While initial discharge measurements showed no significant differences in cardiac sympathetic activity between groups, at a 1-year follow-up, the RIPC group exhibited lower sympathetic nerve activity and better imaging results in nonculprit lesions, indicating a lasting positive effect of RIPC.
Background: Although mild cognitive impairment (MCI) has received much attention as a precursor of dementia, its prognostic role has not been fully clarified in patients with heart failure (HF).
Methods And Results: We studied 274 patients admitted for acute decompensated HF. Cognitive function was evaluated using Mini Mental State Examination (MMSE).
A 74-year-old woman with an implanted physiological DDD pacemaker visited our department complaining of palpitations due to atrial fibrillation (AF). Catheter ablation therapy for AF was scheduled. Preoperative multidetector computed tomography showed that the inferior pulmonary vein (PV) was a common trunk, and the left and right superior PVs branched from the center of the left atrial roof.

The model for end-stage liver disease excluding international normalized ratio (MELD-XI) score has been shown to be useful for predicting poor outcomes in patients with acute decompensated HF (ADHF). Furthermore, the fibrosis-4 (FIB-4) index, a simple marker to assess liver fibrosis, predicts adverse prognoses in patients with HF as well.
