Contrast stress echocardiography in hypertensive heart disease
نویسندگان
چکیده
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.

Stress echocardiography in special groups: in women, in left bundle branch block, in hypertension and after heart transplantation.
The non-invasive diagnosis of coronary artery disease by exercise electrocardiography is less accurate in women than in men, with a high rate of false-positive results in women. In contrast, recent studies have demonstrated that stress echocardiography in women is more accurate than exercise echocardiography and that the significantly higher specificity of stress electrocardiography may have th...

Myocardial contrast echocardiography (MCE) has an established role in left ventricular assessment by improving the ventricular opacification and endocardial border definition especially in patients with sub-optimal echocardiographic images. With advances in cardiac ultrasound imaging technology and the development of new contrast agents, the clinical utility of this technique has greatly expand...

Cor triatriatum is an acyanotic congenital heart disease. We present a rare case of cor triatriatum sinistrum in a 6-month-old female infant who was presented with cyanosis and failure to thrive. The 2D transthoracic echocardiography and the Doppler color flow imaging showed a proximal venous chamber communicating to the distal left atrium through restrictive opening to the low-pressure, dis...
