[Results of percutaneous coronary angioplasty in patients with stable and unstable angina]. / Serganciuju stabiliaja ir nestabiliaja krutines angina perkutanines vainikiniu arteriju angioplastikos rezultatai.

Percutaneous coronary angioplasty is very well known percutaneous revascularization procedure. Results of the percutaneous coronary angioplasty vary according to the stage of ischemic heart disease. The aim of our study was to evaluate and to compare the results of percutaneous coronary angioplasty in patients with stable and unstable angina. We analyzed data from 1148 patients in both groups. The extent of atherosclerosis was significantly higher in unstable angina group, however there was no significant difference in procedural as well in in-hospital outcomes between two groups. Success rate was 86% in unstable angina group and 83.3% in stable angina group. Major adverse cardiac events occurred in 1.48% patients with no difference in both groups. Left ventricular ejection fraction and end-diastolic diameter improved more in unstable angina group.

UNLABELLED: The comparative value of different factors of reperfusion technique and strategy in restoring of myocardial function is underestimated. The aim of this study is to assess the value of reperfusion strategy for restoring of myocardial function in follow-up period. MATERIAL AND METHODS: From 1999 to 2001, 4260 patients with acute coronary syndromes were analyzed. Coronarography was performed for 2990 patients and percutaneous coronary interventions - for 1257 patients. QRS score was calculated; electrocardiogram and echocardiograms were done for 248 patients with acute myocardial infarction after reperfusion therapy by percutaneous transluminal coronary angioplasty (PTCA) (228 patients) and by stenting (20 patients). Urgent PTCA was used for 114 patients, urgent stenting for 14 patients, delayed PTCA for 114 patients and delayed stenting for 6 patients. RESULTS: Coronarography was performed for 66% of all hospitalized patients; percutaneous coronary interventions - for 825 (45.6%) of patients with acute myocardial infarction and only for 11.7% of patients with unstable angina pectoris. In hospital period QRS score increased for all patients with the exception of patients with delayed stenting (p from 0.05 to 0.001). LVEF had tendency to increase in all groups of patients during 3 months. CONCLUSIONS: Coronarography can be performed for 65-70% of hospitalized patients with acute coronary syndromes and percutaneous coronary interventions for 45% of patients with acute myocardial infarction. Differences in reperfusion strategy do not have manifest value on restoring of left ventricle function.

[Cocaine-induced myocardial infarction (clinical case report)]. / Kokaino sukeltas miokardo infarktas (klinikinis atvejis).

Cocaine abuse has been associated with various cardiovascular complications, including angina pectoris, myocardial infarction, and sudden cardiac death. The first report of myocardial infarction temporally related to the recreational use of cocaine appeared in 1982. This article discusses the possible pathological mechanisms underlying the pathogenesis of myocardial ischemia and infarction secondary to cocaine abuse, and current ideas on the management of cocaine-induced myocardial infarction. We report a case of acute myocardial ischemia in a young healthy male patient and his 5-year follow-up.
