Objective: The present study compared heart rate variability (HRV) parameters in patients with coronary artery ectasia (CAE) and coronary artery disease (CAD). Methods: The study population consisted of 60 consecutive patients with CAE (14 women; mean age 51.63+-7.44 years), 60 consecutive patients with CA (15 women; mean age 53.67+-9.31 years), and 59 healthy individuals (13 women; mean age 52.85+-8.19 years). Electrocardiograms, 24-hour Holter analyses, and routine biochemical tests were performed, and clinical characteristics were evaluated. Coronary angiography images were analyzed. Time-domain HRV parameters, including the standard deviation (SD) of normal-to-normal intervals (SDNN) and the root mean square of difference in successive normal-tonormal intervals (RMSSD) were evaluated, as were frequencydomain HRV parameters including low-frequency (LF), very lowfrequency (VLF), high-frequency (HF), the proportion derived by dividing low- and high-frequency (LF/HF), and total power (TP). Results: SDNN was lower in both the CAE and CAD groups, compared to the healthy group (140.85+-44.21, 96.51+-31.28, and 181.05+-48.67, respectively). A significant difference in RMSSD values among the groups was determined (p=0.004). Significantly decreased VLF and HF values were found in the CAE group, compared with the healthy group (VLF p

Myocardial bridging (MB) is defined as the intramural course of a major epicardial coronary artery, and is mostly confined to the left ventricle and the left anterior descending coronary artery (LAD). MB is a common congenital abnormality of a coronary artery, and is usually thought to be a benign anatomical variant. Although rare, previous studies have reported that patients with MB may suffer from myocardial ischemia, myocardial infarction (MI), arrhythmias, and even sudden death. Therefore, the diagnosis and treatment of MB are both important. Since MB is congenital, its disappearance is unlikely. We here report a very rare case of disappearance of MB after inferior MI.
