  • Title: Contrast stress echocardiography in hypertensive heart disease.
    Author: Lønnebakken MT, Rieck AE, Gerdts E.
    Journal: Cardiovasc Ultrasound; 2011 Nov 18; 9():33. PubMed ID: 22093163.
    Abstract:
    Hypertension is associated with atherosclerosis and cardiac and vascular structural and functional changes. Myocardial ischemia may arise in hypertension independent of coronary artery disease through an interaction between several pathophysiological mechanisms, including left ventricular hypertrophy, increased arterial stiffness and reduced coronary flow reserve associated with microvascular disease and endothelial dysfunction. The present case report demonstrates how contrast stress echocardiography can be used to diagnose myocardial ischemia in a hypertensive patient with angina pectoris but without significant obstructive coronary artery disease. The myocardial ischemia was due to severe resistant hypertension complicated with concentric left ventricular hypertrophy and increased arterial stiffness.
