Since July 2002 we have been conducting a study of efficacy of prehospital thrombolytic therapy combined with subsequent endovascular procedures in the treatment of patients with acute myocardial infarction. Fifty nine patients received prehospital fibrinolysis with tissue-type plasminogen activator (TPA, n=28) or streptokinase (n=31) within 6 hours after onset of symptoms. TPA infusion compared with that of streptokinase was associated with smaller ischemic myocardial damage and lower frequency of side effects (3.6 and 38.7%, respectively). Angioplasty or stenting of infarct related arteries were carried out in 47 of these patients. The group of patients subjected to endovascular interventions was characterized by a low rate of in-hospital cardiac events and zero mortality.

Combination of the methods of interventional cardioangiology with current techniques of vascular surgery allows a considerable broadening of the potential for the treatment of different signs of multifocal atherosclerosis in "high risk" patients. For instance, a 70-year-old patient (height 152 cm, weight 32 kg; initial concentration of serum creatinine 174 mumol/l) with the clinical evidence of progressing angina pectoris and critical ischemia of the lower extremities underwent angioplasty (the first stage) using a transradial access and stenting of the critically narrowed circumflex branch of the left coronary artery and angioplasty of the proximal segment of the right coronary artery. Good angiographic and clinical results were obtained. This provided a possibility of accomplishing aortofemoral bifurcation bypass grafting. So, the staged combined treatment made it possible to eliminate the life- threatening signs of multifocal atherosclerosis and to improve disease prognosis in an elderly patient classified with a group of inoperable subjects.
