What is occlusion of left anterior descending artery?
Occlusion of the left anterior descending coronary artery (LAD) may cause infarction of the anterior wall of the left ventricle, manifested as precordial ST-segment elevations. Inferior ST-segment elevations due to occlusion of a LAD may reflect an ischemia of wrapped LAD artery [1], [2].
What are the consequences of an occlusion of the LAD?
LAD occlusion resulted In immediate decrease in cardiac output, heart rate, and blood pressure, an increase in TPR, and cardiac rhythm changes including premature ventricular beats, ventricular tachy- cardia, and occasionally ventricular fibrillation.
Why are blockages of the left anterior descending artery so critical?
“The LAD is a very important blood vessel,” Chetcuti says. “It supplies a significant amount of blood flow to the heart muscle — so there can be big consequences when that territory is jeopardized.” Caused by lifestyle and genetic factors, that harmful blockage typically builds over time.
How do you treat left anterior descending artery blockage?
Stenting has become the preferred treatment for isolated lesions of the left anterior descending coronary artery. The combination of balloon angioplasty, stenting, and antiplatelet treatment has reduced the rate of acute dissections and restenoses even among lesions with complex morphology.
Can you live with blocked arteries?
Coronary Artery Disease (CAD) is treatable, but there is no cure. This means that once diagnosed with CAD, you have to learn to live with it for the rest of your life. By lowering your risk factors and losing your fears, you can live a full life despite CAD.
Can the left anterior descending artery be stented?
Conclusions: Stenting of left anterior descending coronary stenosis was safe and effective in a long-term analysis. The survival rate was high and the incidence of new revascularization was low.
