Risk factors for stent thrombosis

Risk factors for stent thrombosis

Risk factors for stent thrombosis can be divided into those due to unfavourable anatomical characteristics or procedural characteristics and those due to unfavourable clinical characteristics

Unfavourable anatomical/procedural characteristics at risk of stent thrombosis and life threatening complications:

  1. Long stented segments
  2. Multiple stents
  3. Overlapping stents
  4. Small vessels
  5. Bifurcation lesions
  6. Left main and last remaining vessel – more of a risk for life threatening situation if stent thrombosis occurs

Unfavorable clinical characteristics at risk for stent thrombosis/life threatening complications:

  1. Recent acute coronary syndrome (ACS)
  2. History of previous stent thrombosis
  3. Low left ventricular ejection fraction
  4. Chronic kidney disease
  5. Diabetes mellitus
