Insights
This study details a successful complex treatment for anterior myocardial infarction, restoring coronary blood flow within four hours. The patient experienced a complete recovery of left ventricular function within 16 days.
Area of Science:
- Cardiology
- Interventional Cardiology
Background:
- Acute anterior myocardial infarction presents significant hemodynamic compromise.
- Timely restoration of coronary blood flow is critical for myocardial salvage and ventricular function.
Observation:
- A 27-year-old patient with hemodynamically significant anterior myocardial infarction underwent a complex interventional procedure.
- Treatment involved intravenous streptokinase, N-acetylcysteine, and percutaneous transluminal coronary angioplasty.
Findings:
- Coronary artery lumen and blood flow were normalized within four hours of symptom onset.
- Left ventricular ejection fraction improved from 45% on day one to 64% before discharge, indicating functional recovery.
Implications:
- This case demonstrates the efficacy of a multi-modal approach in managing acute myocardial infarction.
- Rapid intervention can lead to significant recovery of left ventricular function, improving patient outcomes.
Abstract:
In a 27-year-old patient with an infarction of the anterior myocardial wall, significant from the haemodynamic aspect, a complex procedure is described by which in the course of four hours after the beginning of complaints normalization of the lumen and blood flow of the coronary artery supplying the infarction focus was achieved. The authors used thrombolytic intravenous treatment which involved infusion of 1.5 million u. of streptokinase (Streptase, Boehringer, Ingelheim) in the course of 45 mins., N-acetylcysteine 2.0 g i.v. (Broncholysin, Spofa) and percutaneous transluminal coronary angioplasty. In the course of 16 days the left ventricular function recovered completely: the ejection fraction was 67% before the infarction, on the first day of infarction 45% and before discharge 64%.
