Type 1 variant includes patients with normal coronary arteries without predisposing factors for coronary artery disease, in whom the acute release of inflammatory mediators can induce either coronary artery spasm
without an increase in cardiac enzymes and troponins or coronary artery spasm
progressing to acute myocardial infarction with raised cardiac enzymes and troponins.
In the present case report, recurrent episodes of coronary artery spasm
and subsequent myocardial infarction appeared to be triggered by the ingestion of rice.
In conclusion, coronary artery spasm
related to endothelial effects of cigarette smoking is a possible mechanism of acute myocardial infarction.
Some people, such as those with a coronary artery spasm
, may have angina when they are resting.
5) Three main things can cause this: a blood clot (thrombus), atherosclerosis, and coronary artery spasm
A coronary artery spasm
is a brief, temporary narrowing of the artery that supplies blood to the heart.
Global coronary artery spasm
caused takotsubo cardiomyopathy.
However, coronary artery spasm
followed by thrombus formation is considered the most likely pathophysiologic mechanism.
It is important to note that assuming you do not have coronary artery spasm
, the prognosis for people without major blockages on the angiogram is generally quite good.
Coronary artery spasm
and acute plaque rupture have been investigated with conflicting results.
Diltiazem hydrochloride is the generic equivalent of Marion Merrell Dow's Cardizem(R) and is indicated for the management of chronic stable angina and angina due to coronary artery spasm
Type I variant includes patients with normal coronary arteries and Type II variant includes patients with culprit but quiescent pre-existing atheromatous disease where the acute release of inflammatory mediators can induce coronary artery spasm
with normal or elevated cardiac enzymes and troponins (3-5).
Abstract: The authors present a 20-year follow-up of a patient with well-documented coronary artery spasm
, who initially presented with syncope.
