Literature review—efficacy of percutaneous coronary intervention and associated kidney injury and mortality.

S. No.	Author, journal	Year	Design	Conclusion
1	Valsson et al Intensive Care Med	1996	Prospective	• The improvement in renal blood flow and glomerular filtration rate may be of potential therapeutic value to prevent or treat exaggerated renal vasoconstriction in patients with acute renal impairment following cardiac surgery
2	Liu et al Biomed Res Int	2016	Prospective	• Combined with hydration, exogenous BNP administration before CM effectively decreases CIN incidence in CKD patients
3	Xing et al Heart Vessels	2016	Prospective	• The incidence of renal injury was not different between rhBNP and nitroglycerin in STEMI-HF patients with mild renal insufficiency • Infusion of rhBNP was associated with a decline in the rate of CIN
4	Morikawa et al J Am Coll Cardiol	2009	Prospective	• ANP administration is effective in the prevention of CIN in patients with chronic renal failure, and the effect was maintained for 1 month
5	Sezai et al J Am Coll Cardiol	2011	Prospective	• The improvement in renal blood flow and glomerular filtration rate may be of potential therapeutic value to prevent or treat exaggerated renal vasoconstriction in patients with acute renal impairment following cardiac surgery
