The landmark message from these and other

studies, which was incorporated into the 2007

NSTEACS Guidelines, is that prevention of

bleeding MUST be regarded at least as important

as the prevention of major ischemic events, such as

myocardial infarction.

Major bleeding (with or without blood product transfusions) has emerged as a powerful independent predictor of early and late mortality in pts with NSTEMI, STEMI and is at

least as important as MI and myocardial

reinfarction

Conclusion

No significant difference between radial and

femoral access in primary outcome of death, MI,

stroke or non-CABG major bleeding

Rates of primary outcome appeared to be lower

with radial compared to femoral access in high

volume radial centres and STEMI

Radial had fewer major vascular complications with

similar PCI success

Conclusions

LRA for coronary angiography and interventions is associated with slight but

significant lower fluoroscopy time and radiation dose compared to RRA

The LRA advantage seems to be confined to operators at the beginning of

learning curve (fellows) and to be more pronounced in older patients

Real problems of TRANSRADIAL APPROACH

1. Most centers have no formal TRA program

2. Operators fear technical failure and care for fluoroscopy time

3. Ruin of radial graft after transradial catheterization

• Fatal

• > 2 units of Blood transfusion

• Hypotension requiring inotropes

• Leading to hemoglobin drop of ≥ 5 g/dl

• Requiring surgical intervention

• ICH or Intraocular bleeding leading to significant vision loss
