Background: An association between heart rate variability (HRV) and cardiac events in certain diseases has been demonstrated. However, the association with new-onset atrial fibrillation (AF) after coronary artery bypass grafting (CABG) is still controversial. This study aimed to investigate the association between HRV and new-onset AF in patients undergoing CABG during a 6-month follow-up.

- * Researchers monitored 119 patients at various intervals (2 days before, 1 week, 3 months, and 6 months after CABG) and found a significant initial drop in HRV after surgery, with partial recovery by 3 months.
- * The findings suggest that the drop in HRV shortly after surgery may stem from the operation itself, but the improvements in HRV over time indicate that autonomic nervous system function may recover as the patients heal.
Article Synopsis
- The study focuses on understanding the risk factors and early surgical outcomes for patients undergoing repair of total anomalous pulmonary venous connection (TAPVC).
- Conducted through a retrospective review of 58 patients, it found that pulmonary hypertensive crisis occurred in 27.59% of cases and low cardiac output syndrome in 6.90%, with several significant risk factors identified.
- The overall survival rate post-surgery was high at 96.55%, highlighting the need for careful preoperative evaluations to enhance surgical outcomes.
Article Synopsis
- The study focuses on the high rates of in-hospital mortality following emergency coronary artery bypass grafting (CABG) in Vietnam, aiming to identify key risk factors by analyzing a large patient cohort.
- Conducted at Hanoi Heart Hospital, the research involved 71 patients from 2017 to 2019, revealing an in-hospital mortality rate of 9.86%, with various pre-, intra-, and post-operative factors significantly impacting survival.
- Major risk factors linked to mortality included pre-existing conditions like diabetes and low ejection fraction, intraoperative issues like prolonged cardiopulmonary bypass time, and postoperative complications such as respiratory failure and serious infections.
