What is Prinzmetal’s angina?
Prinzmetal (or Prinzmetal’s) angina is also called variant angina, angina inversa and vasospastic angina. Angina is the term used to describe chest pain caused by inadequate blood flow to the heart muscle, usually caused by coronary artery disease.
Who is most likely to suffer from Prinzmetal’Sangina?
Men are more likely to suffer Prinzmetal’sangina than women. It also seems to be more common among Japanese people than Caucasians. People with Prinzmetal’sangina are generally younger than those with stable angina; the average Prinzmetal’s angina patient is between 51 and 57 years old.
Is there a link between Prinzmetal angina and migraine?
And as it turns out, people with Prinzmetal angina often are also migraine sufferers. The more severe consequences of Prinzmetal angina are much more likely to occur in smokers, and in people who abuse cocaine or amphetamines.
What causes chest pain with Prinzmetal’Sangina?
The chest pain of Prinzmetal’sangina is caused by coronary artery spasm, an abnormal or involuntary constriction of the muscle in a coronary artery. This spasm makes the diameter of the artery smaller, restricting the supply of blood and oxygen to the heart, causing chest pain.
How is Prinzmetal’s variant angina (PVA) diagnosed?
Prinzmetal’s variant angina (PVA) is a form of angina caused by coronary-artery vasospasm (CAS) and is not associated with exertion. It is diagnosed by history, electrocardiogram, or coronary-artery angiography. Provocative tests, such as the cold-pressor test or intravenous ergonovine maleate, are sometimes used to aid diagnosis of PVA.
When can I stop taking Prinzmetal for angina?
After six to 12 months of treatment, doctors may gradually reduce the medication. Prinzmetal’s angina is a chronic condition that will need to be followed by your healthcare provider even though the prognosis is generally good. Track your angina symptoms with our Angina Log.
Does nitric oxide theory explain Prinzmetal’s angina?
However, there is also research suggesting that the nitric oxide theory doesn’t fully explain Prinzmetal’s angina. Atherosclerosis, the hardening of the arteries caused by the buildup of fatty plaque, impairs the release of nitric oxide, but not everyone with atherosclerosis develops coronary artery spasms.
