Primary Outcome Measures :
  1. Reduction of acute kidney injury (stage 1 or above) at 48-72 hours. [ Time Frame: 48-72 hours ]
    we will measure the incidence of VARC-2 acute kidney injury at 48-72 hours.

Secondary Outcome Measures :
  1. whether endothelial function assessment can predict AKI AKI. [ Time Frame: 2 years ]
    evaluate whether endothelial dysfunction can predict AKI

  2. Prevention of AKI according to chronic statin treatment [ Time Frame: 2 years ]
    we will compare patients with and without statin treatment for the incidence of AKI

  3. Predictive power of abnormal carotid doppler results and AKI incidence [ Time Frame: 2 years ]
    We will evaluate the prognostic ability of carotid doppler for predicting AKI

  4. Predictive power of different biomarkers for predicting AKI and outcome [ Time Frame: 2 years ]
    We will evaluate inflammatory, metabolic and neuroendocrine biomarkers

  5. Whether the RenalGuard system can lower major adverse clinical events (MACE) defined as a composite of all-cause mortality, myocardial infarction, AKI, 30 day readmission rate, and dialysis. [ Time Frame: 2 years ]
  6. the RenalGuard system will lower 30 day readmission rate [ Time Frame: 2 years ]
  7. the RenalGuard system can lower 30 day congestive heart failure exacerbation rate [ Time Frame: 2 years ]
