Teacher: Now, understand the problem? Solve this instance: Question: Are epicardial coronary arteries adequately sized in hypertensive patients?
Answer: Despite an elevated myocardial oxygen demand, maximal dimensions of large coronary arteries are not increased in hypertensive patients, resulting in an elevated coronary flow velocity that may increase longitudinal shear stress at the endothelial surface. This elevated flow velocity might be an important determinant in the pathogenesis of atherosclerosis in hypertensive patients.
