Left Main Stem Disease Symptoms

Left main coronary artery disease is of particular importance because left main stem lms is responsible for 84 of the blood supplied to left ventricle in case of left coronary dominant system the patients with severe lms stenosis have a very high risk of major cardiovascular events because of the extent of ischaemic myocardium.

Left main stem disease symptoms. No clinical features were found to distinguish patients with left main stem stenosis. There was a high incidence of significant proximal stenosis in the branches of the left main stem. 2 in fact during this early era performing coronary. Two types of stroke the most common type of stroke is an ischemic stroke which is caused by a blood.

Leftmainstem coronaryartery disease class 0 normal function class 1 minor general reduction of function class 2 hypokinetic akinetic or aneurysmal area class 3 moderate general reduction of function withorwithoutclass 2 class 4 grossly reduced function with or without class 2. If there is no patent bypass graft to the left anterior descending lad or circumflex artery the disease is then referred to as unprotected left main disease uplm. A brain stem stroke threatens vital bodily functions making it a life threatening condition. Left main stem stenoses were classified as 50 70 or greater than 70 reduction in dia meter of the vessel lumen.

An effective left internal mammary to left anterior descending coronary artery bypass reproducibly provides excellent long term outcomes and as most surgeons have more experience with bypass grafting this approach is widely favoured over surgical angioplasty of the lmca for isolated left main stem disease. Although coronary balloon angioplasty is an established treatment for patients with coronary artery disease the results of balloon angioplasty of unprotected left main coronary artery lmca stenosis have been disappointing because of the high mortality rate in both in hospital 9 1 and follow up periods 1 current in hospital mortality after initial coronary artery bypass graft surgery. A significant stenosis 50 of the left main is present in 4 to 6 of patients who have undergone coronary angiography.
