SPONTANEOUS CORONARY ARTERY SPASM IN LEFT ANTERIOR DESCENDING ARTERY - A CASE REPORT

Coronary artery spasm has been well documented during angiography. Coronary artery spasm should now be considered a well proven clinical entity which may or may not be associated with clinical symptoms and coronary atherosclerosis and may be either spontaneous or iatrogenically induced. The most important clinical entity associated with coronary spasm is that of Prinzmetal's angina. Patients who have variant angina are more likely to develop coronary spasm during angiography. Coronary artery spasm is also likely to occur during coronary angiography as a result of catheter irritation.coronary artery spasm is commonly reported with right coronary artery. We report a case of spontaneous occurrence of coronary artery spasm in left anterior descending artery. Keyword :Coronary Artery Spasm Left Anterior Descending Artery INTRODUCTION: Coronary artery spasm (CAS) is a dynamic and reversible occlusion of an epicardial coronary artery caused by focal or diffuse constriction of the smooth muscle cells within the arterial wall. Coronary artery spasm quite common during coronary angiogram and is more commonly reported in right coronary artery. It can cause profound morbidity including myocardial infarction and mortality as significant proportion of patients continued to have symptoms despite optimal medical management. It is a variant form of angina initially described by Prinzmetal and colleagues (Prinzmetal or variant angina) in 1959. We herein report a case of CAS and management of such patients remained a debate with the absence of hard scientific evidence and guidelines.
