Exercise-provoked esophageal motility disorder in patients with recurrent chest pain

Figure 1 Comparison of two Kaplan-Meier curves in patients with and without signs of exercise-provoked esophageal spasm. EPES: Exercise-provoked esophageal spasm; EPES-: Patients, in whom the percentage of simultaneous contractions within the treadmill stress test did not exceed 55%; EPES+: Patients in whom the percentage of simultaneous contractions within the treadmill stress test exceeded 55%.

Figure 2 Comparison of four Kaplan-Meier curves in patients with and without signs of exercise-provoked esophageal spasm and a narrowing of coronary arteries > 50%. EPES: Exercise-provoked esophageal spasm; CAD: Coronary artery disease; CAD+EPES-: Patients with significant (> 50%) coronary artery narrowing in coronary angiography, in whom the percentage of simultaneous contractions within the treadmill stress test did not exceed 55%; CAD+EPES+: Patients with significant (> 50%) coronary artery narrowing in coronary angiography, in whom the percentage of simultaneous contractions within the treadmill stress test exceeded 55%; CAD-EPES-: Patients without significant coronary artery narrowing in coronary angiography, in whom the percentage of simultaneous contractions within the treadmill stress test did not exceed 55%; CAD-EPES+: Patients without significant coronary artery narrowing in coronary angiography, in whom the percentage of simultaneous contractions within the treadmill stress test exceeded 55%.
