Coronary 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 کاملCatheter-induced spasm of the left main coronary artery.
Catheter-induced spasm of the left main coronary artery is rare during catheterization. We present several cases in which the occurrence of both ostial left main and right coronary spasm suggests that multiple sites of spasm may be a clue to this important diagnosis.
متن کاملMultivessel coronary spasm in patients with variant angina: a study with intracoronary injection of acetylcholine.
Multivessel coronary spasm has been described but its incidence in patients with variant angina still remains unclear. Thirty-three patients with variant angina were studied during coronary angiographic examination with selective intracoronary injection of acetylcholine (ACh). In all but three patients, the location of ischemia during attack was determined by the electrocardiographic findings, ...
متن کاملUsefulness of accelerated exercise following mild hyperventilation for the induction of coronary artery spasm : comparison with an acetylcholine Test.
STUDY OBJECTIVES This study was performed to compare the results of accelerated exercise following mild hyperventilation and a standard acetylcholine (ACh) test for the induction of coronary artery spasm in patients with drug-induced coronary artery spasm. METHODS AND RESULTS The subjects were 74 patients with angiographically confirmed coronary artery spasm who were examined using accelerate...
متن کاملRole of protein kinase C-mediated pathway in the pathogenesis of coronary artery spasm in a swine model.
BACKGROUND The intracellular mechanism of coronary artery spasm is still unknown. The pathway mediated by protein kinase C (PKC) is an important intracellular process of various cellular responses, including vascular smooth muscle contraction. Thus, we examined the role of the PKC-mediated pathway in the pathogenesis of coronary artery spasm in our in vivo swine model. METHODS AND RESULTS Sev...
