The Relationship Between the Coronary Anatomy and Angina Pectoris During Stent Balloon Dilatation in Patients Undergoing Percutaneous Coronary Intervention

OBJECTIVE
Angina pectoris (AP) is defined as a clinical symptom characterized by different sensations such as pressure-heaviness, burning, squeezing, or discomfort in different parts of the body including retrosternum, chest, jaw, neck, shoulders, and back. There are limited publications regarding the effect of coronary artery disease localization on the placement, character, and severity of AP. This study aimed to investigate the relationship between the frequency of development of AP secondary to myocardial ischemia, which occurs during percutaneous coronary intervention (PCI), its character, severity, localization, and coronary anatomy.


METHODS
A total of 128 patients were included in the study, and 146 lesions were treated in these patients.


RESULTS
While 31.1% of patients who underwent PCI of right coronary artery (RCA) did not describe any complaint, this rate was similar in patients undergoing PCI of left anterior descending (LAD) and circumflex (Cx) arteries (23.7% and 19.1%, respectively). Whereas pressure-heaviness was observed frequently in PCI of LAD and Cx arteries, burning was dominant symptom in PCI of RCA. Isolated retrosternal and left thoracic regions were the most common localization in all main coronary arteries. Epigastric localization was occured most frequent in PCI of RCA. In terms of the severity of angina, difference was not observed between the three coronary arteries.


CONCLUSION
Pressure-heaviness angina was common observed during PCI of LAD and Cx and burning angina was frequent during PCI of RCA. The severity of AP was similar between the three main coronary arteries.
