[The effects of delayed transluminal balloon coronary angioplasty in myocardial infarct patients with early thrombolytic recanalization of the coronary artery: the results of dynamic quantitative angiography].

As many as 71 patients with the developing large-focal myocardial infarction (MI) were entered into the study. The purpose was to examine the dynamics of the status of the coronary arteries and left ventricular function in MI patients with early recanalization of the infarct-related artery (IRA) as a result of thrombolytic therapy (TLT) and delayed transluminal coronary angioplasty (TCA). Coronary arteriography and left ventriculography were provided 3 times to all the patients: within the first 4 hours of the disease (in combination with TLT), on days 4-6 of the disease (in combination with TCA of the IRA), and after 6 months of observation. It is concluded that the combined use in MI patients of coronary thrombolysis within the first 4 hours of the disease and delayed TCA (on days 4-6 of the disease) ensure steady recovery of IRA patency, with an insignificant residual stenosis of the artery. At the same time the patients demonstrated improvement of local contractility of the deranged compartment of the left ventricle by the 6th month of observation. Restenosis of the recanalized IRA that occurs during 6 months of observation after the interventions performed does not affect the recovery of left ventricular function.
