[Size of viable myocardium and collateral blood flow in patients with coronary artery occlusion].

The aim of the study was to investigate correlation between collateral blood flow to occluded coronary vessel and the size of viable myocardium in the area fed by that artery. Total 295 patients with coronary artery occlusion were divided into 2 groups. The 1st group included 193 patients with the history of Q-wave myocardial infarction (MI), the 2nd group - 102 patients with non-Q-wave MI or without MI.

[Acute diffuse thrombosis of left coronary artery complicating coronary angioplasty].

The paper presents a case report for successful treatment of acute diffuse thrombosis developed in left coronary artery after coronary angioplasty fulfilled for 39-year-old patient with acute coronary syndrome. Heparin resistance accompanied by intracoronary intervention triggered severe ascending thrombosis of the whole anterior descending artery with involvement of circumflex artery ostium. Therapeutic measures included: repeated Heparin bolus injection (total 27,000 U), bolus intracoronary Streptokinase injection (500,000 U) with subsequent Streptokinase infusion (1,000,000 U in 1 hour), stenting of circumflex artery ostium for thrombus mechanical destruction.
