Peripheral artery disease and multivessel coronary artery disease significantly increase the risk of acute kidney injury (AKI) after coronary angiography. Patients with higher initial creatinine levels also face a greater chance of developing AKI.
Area of Science:
- Cardiology
- Nephrology
- Interventional Cardiology
Background:
- Coronary angiography is a common procedure, but it carries a risk of acute kidney injury (AKI).
- Identifying patient characteristics associated with AKI is crucial for risk stratification and prevention strategies.
Purpose of the Study:
- To identify patient characteristics associated with acute kidney injury (AKI) following coronary angiography with or without percutaneous coronary intervention.
Main Methods:
- Retrospective, single-center study of 350 patients from October 1, 2017, to September 30, 2018.
- AKI defined as a creatinine rise >0.3 mg/dL within 48 hours of coronary angiography.
- Multivariable regression analysis was used to identify independent predictors of AKI.
Main Results:
- The incidence of AKI was 8.8% (41 out of 350 patients).
- Patients with AKI had higher rates of hypertension, hyperlipidemia, diabetes mellitus, and heart failure.
- Peripheral artery disease (OR=12.4), multivessel coronary artery disease (OR=11.9), and initial creatinine >1.5 mg/dL (OR=4.4) were significantly associated with increased AKI risk.
Conclusions:
- Peripheral artery disease, multivessel coronary artery disease, and elevated baseline creatinine are key risk factors for AKI post-coronary angiography.
- These findings can aid in identifying high-risk patients and implementing preventive measures.

Blood Studies for Cardiovascular System I: Cardiac Biomarkers
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
Dialysis
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
