[ST segment elevation during dipyridamole stress testing in a patient without coronary lesions].
نویسندگان
چکیده
We describe a patient who presented transient ST-segment elevation and typical chest pain during an ischemia test with dipyridamole and technetium-tetrofosmin. Chest pain and electrical alterations disappeared promptly with sublingual nitroglycerin. Coronary angiography showed no epicardial lesions, and coronary vasospasm was suspected. We discuss possible explanations for this complication.

Induction of coronary spasm after dipyridamole administration.
The stress test, whether performed conventionally or with imaging techniques, is the most widely used method in clinical practice to demonstrate myocardial ischemia in patients with chest pain. A pharmacological stress test is usually indicated in patients who cannot do physical exercise. Although several drugs are currently available to induce ischemia, for many years dipyridamole has been the...
متن کاملST-Segment Elevation during Dobutamine Stress Echocardiography in a Patient with Normal Coronary Arteries
Dobutamine stress echocardiography (DSE) is an effective modality for determining the presence of myocardial ischemia from obstructive coronary artery disease (CAD) [1]. Several large studies have deemed DSE a largely safe imaging tool, with minimal side effects [2-5]. The most serious and rare side effects being sustained ventricular tachycardia, intracranial hemorrhage, and myocardial infarct...

متن کاملCoronary Artery Spasm During Dobutamine Stress Echocardiography: A Case Report
Dobutamine stress echocardiography (DSE) has been widely used as a diagnostic and prognostic modality in the management of stress. DSE is associated with limited complications and adverse effects on the health of patients. In this case report, we described a 42-year-old female patient with dobutamine-induced coronary artery spasm with history of exertional dyspnea, which had deteriorated recent...
متن کاملPhysiological basis for angina and ST-segment change PET-verified thresholds of quantitative stress myocardial perfusion and coronary flow reserve.
OBJECTIVES This study aimed to determine the quantitative low-flow threshold for stress-induced perfusion defects with severe angina and/or significant ST-segment depression during dipyridamole hyperemia. BACKGROUND Vasodilator stress reveals differences in regional perfusion without ischemia in most patients. However, in patients with a perfusion defect, angina, and/or significant ST-segment...
