- Abstract:
- The paper presents an overview of the recent diagnostic and therapeutic feasibilities in acute coronary heart disease. In unstable angina the leading symptoms are new onset or increasing anginal pain or resting pain as well as ST-T-changes in the ecg without a rise in enzymes. Coronary arteriography shows double or triple vessel disease (70%), a left main stenosis (10 to 15%) or normal coronary arteries (10 to 15%). The treatment of unstable angina in the CCU consists of Nitroglycerin-infusion together with calcium channel blockers and/or betablockers. With this regimen, 80% of patients may be stabilized within 24 to 48 hours. Thereafter coronary arteriography is performed to settle the further therapeutic regimen (PTCA, CABG, medical therapy). Acute myocardial infarction is characterized by persisting (more than 30 min) pain, ST-T-changes in the ecg with or without development of Q-waves indicating irreversible myocardial damage. Angiographically, usually a subtotal or total occlusion of the corresponding artery is found. Aims of therapy in acute myocardial infarction is-besides treatment of complications like arrhythmias and left ventricular failure-reperfusion of the myocardium with reopening of the occluded vessels by intracoronary or systemic thrombolysis. Recently, also clot-specific streptokinase derivates and plasminogen activators are used with fewer bleeding complications. After recanalization of the vessel a persisting stenosis should be relieved either by PTCA or CABG to avoid reocclusion. However, these active forms of treatment can only be performed, if the patient reaches the hospital within 4 to 6 hours after the onset of ischemia.
