Images in cardiovascular medicine. Spontaneous echocardiographic wall motion abnormalities in variant angina.
Variant angina, defined as spontaneous angina pectoris associated with transient ST-segment elevation, is usually caused by episodic coronary spasm. At present, coronary artery spasm is a reversible coronary stenosis that limits coronary blood flow under resting conditions. Prinzmetal first described this type of angina pectoris as a distinct entity in 1959. Although several hypotheses have bee...
متن کاملEchocardiographic Wall Motion Abnormalities in Hypertensive Patients With Electrocardiographic Left Ventricular Hypertrophy
There is limited information on correlates of left ventricular wall motion (WM) abnormalities in ambulatory patients with hypertension and ECG left ventricular hypertrophy by Cornell voltage-duration product and/or Sokolow-Lyon voltage criteria. Therefore, we assessed the prevalence and the correlates of echocardiographic global and segmental left ventricular WM abnormalities in 942 hypertensiv...
متن کاملEchocardiographic study of the abnormal motion of the posterior left ventricular wall during angina pectoris.
mean systolic endocardial velocity (SEV) was 4.1 + 0.7 cm/sec, and the systolic endocardial excursion (SEE) was 1.4 + 0.3 cm. The maximal diastolic endocardial velocity (DEVM) was 18 3 cm/ sec, and the mean early diastolic endocardial velocity (DEV) was 9.4 + 1.7 cm/sec. Exercise in 20 normals caused a significant increase in SEVM, SEV, DEVM, and DEV, but not SEE. In no instance did any of thes...

There is limited information on correlates of left ventricular wall motion (WM) abnormalities in ambulatory patients with hypertension and ECG left ventricular hypertrophy by Cornell voltage-duration product and/or Sokolow-Lyon voltage criteria.

متن کاملComparison of two-dimensional echocardiographic wall motion and wall thickening abnormalities in relation to the myocardium at risk.
Previous 2DE studies have suggested that left ventricular wall thickening determinants of regional left ventricular function may be more precise than left ventricular wall motion parameters in the assessment of myocardial ischemia and infarction. To study the relationship between regional wall motion and regional wall thickening abnormalities relative to myocardial ischemia, we performed 2DE in...
