Occurs in approximately 10% of patients. May be associated with renin-angiotensin blockade.[59]

short term

Occurs in approximately 10% of patients.[60]

Evaluation of tachycardia

short term
low

Occurs in approximately 5% of patients undergoing percutaneous intervention.[65][66]

short term
low

Occurs in approximately 1% to 2% of patients undergoing percutaneous intervention.[67]

short term
low

Occurs in approximately 5% to 7% of patients undergoing percutaneous intervention.[68]

short term
low

Occurs in approximately 0% to 5% of patients undergoing percutaneous intervention.[43][64]

long term
medium

Most patients with high-degree stenosis (>75% reduction in vessel diameter) tend to progress to total occlusion.[57] Approximately 10% of patients have unilateral stenosis >50%.[58]

long term
medium

Overall there is no difference in kidney outcomes between patients treated medically versus those undergoing angioplasty.[54]

long term
low

Occurs in approximately 2% of patients undergoing percutaneous intervention.[68][69]

variable
medium

Restenosis rates after percutaneous revascularization, with or without stenting, range from 10% to 21%.[54]

variable
low

Complication after CT angiogram or conventional angiography ± intervention.

Patients with chronic kidney disease or diabetes, or who receive larger contrast doses, are at increased risk. Occurs in as many as 25% of these patients.[61][62]

Causes acute renal failure. May require dialysis in a small percentage of patients.

N-acetylcysteine, bicarbonate, or saline IV prehydration and use of lowest possible doses of low-osmolar/iso-osmolar contrast agents should be considered in order to decrease the risk for radiocontrast nephropathy.[61][62]

variable
low

Reported in 1% to 2% of patients undergoing percutaneous intervention.[54][63][64]
