Nifedipine blockade of ergonovine-lnduced coronary arterial spasm: Angiographic documentations

Association of plasma level of malondialdehyde-modified low-density lipoprotein with coronary plaque morphology in patients with coronary spastic angina: Implication of acute coronary events

“…Angiographically, coronary vasospasm assumes one of two morphological forms [2]. Focal vasospasm has been reported to be more likely to be associated with acute coronary events as compared with diffuse vasospasm [3,4].…”

Spontaneous and diffuse coronary artery spasm unresponsive to conventional intracoronary pharmacological therapy: A case report

“…Specifically, high efficacy rates have been demonstrated with nifedipine, diltiazem, verapamil [17], and amlodipine [18]. Sublingual nifedipine has been shown to relieve the angiographic coronary artery spasm as well [19]. Nicrondil, also an effective maintenance therapy, causes vasodilatation by interfering with activation of voltage-dependant calcium channels and with release of calcium from intracellular sequestration sites [20].…”

Editorial: Coronary artery spasm

“…Coronary artery spasm can occur prior to cannulation of the vessel by the tip of the catheter (ie, spontaneous), but in most instances it is catheter induced [4] (ie, iatrogenic). It can be provoked by ergonovine injection [5] and relieved by nitrates or nifedipine [6]. Coronary artery spasm is also considered an integral part of Prinzmetal's variant angina [7] with or without fixed coronary artery lesions.…”
