Yun D, Choi Y, Lee SP, et al. - In this retrospective study of 8,176 adult patients who underwent percutaneous coronary intervention (PCI), researchers assessed the predictability of renal progression on the basis of admission as well as discharge blood pressure (BP) and BP threshold values, given the possibility of impaired renal function due to high BP post-PCI. A doubling of serum creatinine levels, ≥ 50% reduction of the estimated glomerular filtration rate, or development of end-stage renal disease defined renal progression. The participants were observed over a median duration of 7 years. Findings revealed a link between high systolic BP at discharge and renal progression post-PCI, especially when the value was ≥ 125 mmHg. This can be applied as a risk classification as well as potential target of renoprotective therapies.
