- CABG should be performed in patients with asymptomatic ischemia or mild angina who have significant left main coronary artery stenosis.(Level of Evidence: A )
- CABG should be performed in patients with asymptomatic ischemia or mild angina who have left main equivalent: significant (greater than or equal to 70%) stenosis of the proximal LAD and proximal left circumflex artery. (Level of Evidence: A )
- CABG is useful in patients with asymptomatic ischemia or mild angina who have 3-vessel disease. (Survival benefit is greater in patients with abnormal LV function; eg, ejection fraction [EF] less than 0.50 and/or large areas of demonstrable myocardial ischemia.) (Level of Evidence: C)
In the pressure-volume loop below, cardiac work is best represented by: the area of the curve the slope of the line from points C to D the distance of the line from points C to D the slope of a line from points A to D .. .. ... .... ... .... .... .... In the pressure-volume loop below, cardiac work is best represented by: the area of the curve Cardiac work is the product of pressure and volume and is linearly related to myocardial oxygen consumption. Cardiac work is best represented by the area of the curve of a pressure-volume loop.
