“…10 Several case reports in literature have described severe intimal thickening consisting predominantly of fibrous tissue without extracellular deposits. 22,23 Nonatherosclerotic causes for nonostial stenosis reported in literature include extrinsic compression of the left main artery by tumor, aneurysm, patent ductus arteriosus, 24 spasm, 25 iatrogenic, 26 and type II hyperlipoproteinemia. 4 In the present study, we found that isolated and significant LMCA disease occurs frequently in association with commonly recognized risk factors for atherosclerotic coronary artery disease.…”

Left main coronary artery disease carries a poor prognosis. The etiology of isolated and significant left main coronary artery (ILMCA) disease is not well understood. Studies so far were limited by small numbers. The authors identified 46 patients with ILMCA disease from their database over 10 years (group I) and compared them with 83 consecutive patients undergoing catheterization (group II). They also compared patients with ostial vs distal ILMCA disease. Group I represented 0.1% of catheterization patients. The demographic profile and atherosclerotic risk factor profile of the 2 groups as well as ostial and distal ILMCA disease were compared. This is the largest study of ILMCA disease. Risk factors for atherosclerosis were commonly seen. Nonatherosclerotic causes of ILMCA disease were not seen. This study suggests coronary atherosclerosis as the predominant cause of ILMCA disease. ILMCA disease is more common in women. Diabetes is more commonly associated with distal ILMCA lesion. There is a trend suggesting that ostial ILMCA lesion is more common in smokers and women.

“…Reflex syncope occurring during exercise is caused by marked hypotension without bradycardia [236,237]. By contrast, postexertional syncope is almost invariably due to autonomic failure or to a neurally-mediated mechanism [238,240,249] and is characterised by hypotension which can be…”

“…It may also reveal coronary artery spasm or congenital abnormalities (single coronary artery, anomalous origin of right coronary artery or coronary arteriovenous fistula as a cause of syncope [249,250]. In case of suspected coronary spasm, the ergometrine test during coronary angiography may be indicated [251].…”
