, serotonin and histamine cause vasodilation by inducing the release of nitric oxide (NO) from the endothelial level, but its dysfunction may induce episodes of vasospastic angina (Yasue 2008).
Another limitation was the possibility of underlying coronary artery spasm in patients with Cardiac Syndrome X, which was excluded using a hyperventilation test, although the ergonovine
test would have been the ideal test in this contest.
Tryptase levels are elevated during spontaneous ischemic episodes in unstable angina but not after the ergonovine
test in variant angina.
3] Regardless, Davis (1959) also suggests ballistocardiogram recording after smoking a cigarette or after injection of potent vasoconstrictors like ergonovine
and pitressin as promising, yet cautious, endeavors.
Alveda's marketed injectable products includes atropine sulphate, acetylcysteine, dimenhydrinate, ergonovine
maleate, furosemide; irinotecan, lidocaine, lidocaine with epinephrine, piperacillin tazobactam, methylene blue, naloxone, succinylcholine chloride, sodium chloride' sterile water as well as epinephrine.
The psychoactive agents in morning glory seeds include the ergot alkaloids, ergonovine
and lysergic acid amide (LSA), that resemble lysergic acid diethylamide (LSD) structurally and cause similar psychomimetic effects.
Transient left ventricular ballooning (tako-tsubo cardiomyopathy) soon after intravenous ergonovine
injection following caesarean delivery.
The active chemical agents found in species of morning glory contain ergot alkaloids such as ergine and ergonovine
, which are hallucinogenic.
test is superior to the hyperventilation test, we preferred to use the hyperventilation test instead of the ergonovine
injection to rule out the coronary spasm in patients with CSX, because of the possibility of persistent and severe, painful spasm with ergonovine
is more effective in this capacity than the animal hormone oxytocin, and it also reduces postpartum bleeding, has low toxicity, and acts rapidly.
