FIGURE 2.

Left atrial stiffness is elevated in a large number of women with ischemia but no obstructive coronary artery disease. Data are divided into four quadrants. Vertical line drawn at 12 mmHg left ventricular end‐diastolic pressure (LVEDP), the upper limit of normal. Horizontal line is drawn at 0.59, which is two standard deviations above the average reference control left atrial stiffness index, estimated by assuming all reference control subjects had an LVEDP of 12 mmHg. Women with ischemia and no obstructive coronary artery disease identified as having elevated left atrial stiffness denoted in red
