Coronary Slow Flow Phenomenon Leads to ST Elevation Myocardial Infarction

Taner Sen. Korean Circ J. 2013 Mar.

Abstract

The exact etiology of the coronary slow flow phenomenon (CSFP) is not certain. CSFP is not a normal variant as it is an absolutely pathological entity. Furthermore, CSFP not only leads to myocardial ischemia but it can also cause classical acute ST elevation myocardial infarction, which necessitates coronary angiography for a definite diagnosis.

Keywords: Acute anterior wall myocardial infarction; Slow-flow phenomenon.

The ECG shows marked ST elevation in the anterior precordial leads. This ECG leads to a diagnosis of hyperacute anterior myocardial infarction. ECG: electrocardiography.

This angiographical image (A: left anterior oblique cranial view, B: right anterior oblique view) reveals left sided normal coronary arteries except slow coronary flow in the left anterior descending artery.

The Thrombolysis in Myocardial Infarction (TIMI) frame count for the left anterior descending coronary artery (A and B) was 67-9=58. The corrected TIMI frame count was calculated as 58/1.7=34.1 (normal range 21±3).

After the chest pain ceased, the electrocardiography showed the resolution ST elevation and negative T waves between V 3-6 leads.
