(1) In the context of IHC assays, the effects of these preanalytic variables, such as cold ischemic time, duration and type of tissue fixation, tissue processing technique, and paraffin tissue block and slide age, have all been documented to affect assay performance, (2-8) leading to potentially clinically significant errors.
Current guidelines for ST-elevation myocardial infarction (STEMI) recommend early revascularization with optimal ischemic time <120 min and door-to-balloon time <90 min7.
There were no significant differences between the two groups with respect to donor and recipient ages, duration of dialysis pre-transplant, positivity for PRA, number of HLA mismatches, cold ischemic time, warm ischemic time, primary diseases of the recipients, causes of death of the donors, and donors' serum creatinine levels and body mass index.{Table 1}
PRO also features automatic calculations for fields such as ischemic time and time in fixation to save PAs extra work and to ensure accuracy.
Cold ischemic time was 7 hours and 3 minutes, warm ischemic time was 32 minutes, and portosystemic bypass time was 1 hours and 9 minutes.
Delay leads to a higher total ischemic time which is related to higher mortality in STEMI; however, whether the same applies to de Winter T-wave ECG is unclear [10].
Donor and recipient ages at the HTx time, recipient CV risk factors, etiology (ischemic or nonischemic) of HF leading to HTx, total ischemic time during HTx, acute rejection episodes (first year after HTx), and cytomegalovirus (CMV) infection evaluated monthly during the first year post-HTx, immunosuppressive therapy, and renal function were registered.
The Paragonix SherpaPerfusion Cardiac Transport System combines innovative oxygenated perfusion of organs and safe organ storage with the ultimate goal of extending ischemic time to 12 hours, significantly altering the transportation range of donor hearts.
The general tolerant ischemic time of skeletal muscle is up to 4 hours.
[sup][4] Based on our study, no significant difference of cardiac ischemic time and CPB time was observed between the VRC and suture groups.
This study highlights the need to reconsider the role of door-to- balloon as a performance metric and examine the utility of a broader metric of systems delay such as first medical contact to balloon time as well as total ischemic time, Mehran added.
