Abstract

AIM:

To determine the correlation between episodes of ischaemia in ECG recordings with pathologic gastro-esophageal reflux during simultaneous 24 hour monitoring of ECG and oesophageal pH.

METHODS:

Simultaneous 24 hour monitoring of ECG and oesophageal pH was performed in 30 patients (p) (26 M/4F, aged 39-74) with coronary artery disease of CCS class II-III, CAD was confirmed in coronary angiography. Analysis of the oesophageal pH was performed by using the Polygram programme (PW-version 2.04 Esophogram-version 2.01). ST depression > 1 mm and lasting at least 1 min was regarded as significant in ECG monitoring. Pathologic gastro-esophageal reflux was defined as a drop in pH < 4 lasting more than 5 min. Gastrooesophageal reflux disease (GERD) was diagnosed when a drop in pH < 4 lasted for more than 5% of the monitoring period. Gastro-oesophageal reflux dependent ST depression was defined as an ST depression that occurred during reflux episode and lasted up until 10 min from the end of the reflux.

RESULTS:

26 patients (87%) had a total of 116 episodes of ST depression and 21 out of the 116 episodes (18%) were Gastro-oesophageal reflux time dependent. Fifteen patients (50%), had at least one episode of ST depression, depending on the time of reflux. Pathologic gastro-esophageal reflux was present in 25 patients (85%). In 14 patients (46.6%), the GERD pH criteria were fulfilled. In this group of patients, there was a significantly longer time of total ST depression (total ischaemic burden).

CONCLUSIONS:

1. GERD is a frequent disease in patients with angiographically proven coronary artery disease. 2. Pathological gastroesophageal reflux can induce myocardial ischaemia, which can be determined by analysis of ST depression during 24 hour monitoring of ECG.
