Intravascular and surgical methods of AMI treatment
Intravascular method is based on mechanical restoration of vascular lumen with the help of inflated balloon.
Direct angioplasty is carried out as the primary intervention without preliminary thrombolytic therapy. It is indicated in those cases when its performance is possible within an hour after patient's admission to the hospital, particularly, in development of cardiogenic shock and in absence of risk of bleeding (i.e. in absence of the contraindications for TLT).
The experts of the European commission of cardiologists recommend a direct angioplasty to perform as the alternative to TLT only in those cases when this procedure is carried on by an experienced operator (75 angioplasties per year) and in the institutions where they are perfomed more than 200 per year.
Angiolasty after successful TLT is not recommended. And, on the contrary, in maintained occlusion of coronary artery after TLT, angiolasty may prove to be saving. For example, if in 90 min after TLT a pain syndrome and ST elevation are being kept.
Operation for aorto-coronary shunting in AMI is of a limited significance and may be used in impossibility or failure to perform angioplasty.
