Multivessel coronary artery spasm.
نویسندگان
چکیده
A 60-year-old patient with variant angina was shown to have myocardial ischemia in two different regions supplied by separate major coronary arteries. Neither artery had significant coronary atherosclerotic obstruction. Ventricular fibrillation was noted during ST-segment elevation in anteroseptal leads. The attacks of pain and arrhythmias disappeared during nifedipine therapy.

Multivessel 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, ...

Multivessel coronary spasm resulting to cardiogenic shock and malignant ventricular arrhythmias though rare has been reported in the literature. The disease seems to be more prevalent in Asians. There have been isolated reports of coronary spasm in patients with reactive airway disease. We report the first case of spontaneous multivessel spasm in a male patient with bronchial asthma of Arab eth...
متن کاملCircadian variation of autonomic nervous activity in patients with multivessel coronary spasm.
The present study investigated whether the circadian rhythm of sympathovagal activity is related to the severity of coronary spasm or multivessel coronary spasm. Heart rate variability was examined in 22 consecutive patients with vasospastic angina provoked by intracoronary injection of acetylcholine, who had either multivessel spasm (Group M, n=11 ) or single vessel spasm (Group S, n= 11), in ...

Multivessel or multisegment spasm in patients with known widespread coronary atherosclerotic disease is an infrequent occurrence. We describe a prolonged spasm of both the left main and the left anterior descending artery in a patient with chronic effort angina and multivessel coronary artery disease, who previously underwent percutaneous coronary intervention and drug eluting stents implantati...
متن کاملCoronary Artery Spasm is a Nightmare: a Rare Case of Multi Vessel Coronary Artery Spasm
Coronary artery spasm is not an uncommon event, but its pathophysiologic mechanisms followed by coronary artery vasospasm are not yet completely clarified. Coronary artery spasm can lead to sudden cardiac death due to ventricular arrhythmias or heart block. In the cases of cardiogenic shock secondly to severe coronary artery spasm, IABP is sufficient to support the patient’s hemodynamics, in th...
متن کاملLimited role of coronary angioplasty and stenting in coronary spastic angina with organic stenosis.
OBJECTIVES We investigated the efficacy of percutaneous coronary intervention (PCI) in patients with coronary spastic angina (CSA) and severe organic stenosis. BACKGROUND Coronary spasm occurs at the site of organic stenosis in most patients with CSA and severe stenosis, whereas multivessel spasm occurs frequently in those with normal coronary arteries. The incidence of multivessel spasm and ...
