[Gastroesophageal reflux and the degree of esophagitis in patients with coronary heart disease: impact on myocardial repolarization parameters and cardiac rhythm variability].
The specific features of myocardial repolarizing processes and heart rate variability (HRV) were studied in 67 patients with coronary heart disease (CHD) concurrent with gastroesophageal reflux disease (GERD) (a study group), in 72 patients with CHD and in 46 patients with GERD (comparison groups). Patients with concomitant diseases showed a significant asynchronism of repolarizing processes and decreased HRV. A relationship was established between the presence and magnitude of inflammatory lower esophageal third changes, and the severity of myocardial repolarizing processes, and decreased HRV in patients with CHD + GERD.
