  • 简介:AbstractBackground:It remains unclear whether the outcomes of ST-elevation myocardial infarction (STEMI) patients treated with primary percutaneous coronary intervention (PPCI) during off-hours are as favorable as those treated during on-hours, especially those with a first medical contact-to-device (FMC-to-device) time within 90 min. We aimed to determine whether off-hours admission impacted late outcomes in patients undergoing PPCI and with an FMC-to-device time ≤90 min.Methods:This multicenter retrospective study included 670 STEMI patients who underwent successful PPCI and had an FMC-to-device time ≤90 min from 19 chest pain centers in Beijing from January 2018 to December 2018. Patients were divided into on-hours group and off-hours group based on their arrival time. Baseline characteristics, clinical data, and key time intervals during treatment were collected from the Quality Control & Improvement Center of Cardiovascular Intervention of Beijing by the "Heart and Brain Green Channel" app.Results:Overall, the median age of the patients was 58.8 years and 19.9% (133/670) were female. Of these, 296 (44.2%) patients underwent PPCI during on-hours and 374 (55.8%) patients underwent PPCI during off-hours. Compared with the on-hours group, the off-hours group had a longer FMC-to-device time and fewer patients with FMC-to-device time ≤60 min (P < 0.05). During the mean follow-up period of 24 months, a total of 64 (9.6%) participants experienced a major adverse cardiovascular event (MACE), with 28 (9.1%) in the on-hours group and 36 (9.6%) in the off-hours group (P > 0.05). According to the Cox regression analyses, off-hours admission was not a predictor of 2-year MACEs (P = 0.788). Similarly, the Kaplan-Meier curves showed that the risks of a MACE, all-cause death, reinfarction, and target vessel revascularization were not significantly different between the two groups (P > 0.05).Conclusions:This real-world, multicenter retrospective study demonstrated that for STEMI patients who underwent PPCI within 90 min, off-hours admission was safe, with no difference in the risk of 2-year MACEs compared with those with on-hours admission.

  • 简介:AbstractOn April 3, 2020, a 37-year-old woman successfully completed heart valve replacement after cesarean section 67 hours in the First Affiliated Hospital of Harbin Medical University.The woman underwent the mechanical mitral valve replacement in the same hospital 10 years ago. She used low molecular weight heparin instead of warfarin, when she realized her pregnancy. On March 25, 2020 (28+5 weeks of gestation), due to New York Heart Association class IV, severe pneumonia, type I respiratory failure, the patient was admitted to the hospital for treatment. Three days later, she discharged herself from hospital by refusing the cesarean section. The next day she was re-admitted to the ward because of the worsen symptoms and oliguria. Cesarean section was performed 50 hours after admission. The neonate was 1 400 g; Apgar score was 5 in 1 minute, 8 in 5 minutes, transferred to neonatal intensive care unit. Because of the unrecovered heart function, she was confirmed stuck mechanical prosthetic mitral valves. On April 3, 2020, through multi-disciplinary cooperation, the patient was safe without any life-threatening emergency. Eleven days after the replacement, the patient was discharged smoothly, so was the neonate 33 days after delivery.
