[New approach in the diagnosis of acute coronary syndrome].
CVD are on the first place among death causes in the world. The half of all death at middle age persons is CVD causality, the most often because of ischaemic heart diseases, and there are a few clinic forms: acute coronary syndrome, stabile pectoral angina, variant pectoral angina, syndrome x, and silent myocardial ischemia. Toward definition ACS include clinical manifestation causality of myocardial ischemia due of atherosclerotic plague rupture. ACS include: non-stable pectoral angina non-Q infarction, Q myocardial infarction and sudden cardiac death. Consequence of plague rupture is occlusive thrombus which produces typical ST elevation on ECG after that appearance Q-in ECG with blood markers elevation (Troponin I, T, CK and CK-MB). There are sometimes non-typical ST elevation on ECG with blood markers elevation and chest pain. On that way becomes non-Q infarction. Smaller thrombus make non stable pectoral angina and appearance of ST depression on ECG without blood markers elevation. Sometimes sudden cardiac death is the first sign of coronary disease in the diagnostic management coronary disease due of: clinical symptom of chest pain, ECG (with or without ST elevation) and appearance appsence biochemical blood markers (at myocardial necrosis troponins are present in blood during 14 days, CK-MB is present 3 days). Sometimes echocardiography examination is helpful in estimate of regional kinetic disorders. European society of cardiologists made guidelines for management od ACS without ST elevation and guidelines management of acute myocardial infarction with ST elevation.
