Why the study?
Does the dipyridamole-echocardiography test induce regional dyssynergy, ST segment depression, or chest pain in essential hypertensives with chest pain and normal coronary arteries compared to normotensive controls?

ST depression and chest pain during DET may indicate microvascular dysfunction in hypertensives; leaves open DET specificity and requires prospective validation.
Does the dipyridamole-echocardiography test induce regional dyssynergy, ST segment depression, or chest pain in essential hypertensives with chest pain and normal coronary arteries compared to normotensive controls?
Essential hypertensive patients with chest pain and normal coronary arteries frequently exhibit echocardiographically silent angina and ST segment depression during dipyridamole testing, indicative of microvascular dysfunction.
Lucarini et al. (1989) studied this question.
