Coronary Artery Spasm also know as Variant angina; Angina – variant; Chest pain – Prinzmetal’s; Prinzmetal’s angina; Vasospastic angina.

Causes of Coronary Artery and Chest Muscle Spasm

The spasm often occurs in coronary arteries that have actually not end up being solidified due to plaque accumulation. However, it likewise can happen in arteries with plaque accumulation.

These spasms are due to a squeezing of muscles in the artery wall. They most often take place in simply one area of the artery. The coronary artery might appear normal during screening, but it does not function usually.

About 2% of people with angina (chest pain and pressure) have coronary artery spasm.

Coronary artery convulsion happens most frequently in people who smoke or who have high cholesterol or high blood pressure. It might take place without cause, or it may be triggered by:

  • Psychological stress
  • Exposure to cold
  • Medicines that cause narrowing of the blood vessels (vasoconstriction).
  • Stimulant drugs, such as amphetamines and cocaine.
Chest Muscle Spasm
What Is a Coronary Artery Spasm?

Prinzmetal’s Angina Symptoms

Convulsion might be “silent” (without symptoms) or it might lead to chest pain or angina. If the spasm lasts long enough, it may even cause a heart attack.

The primary symptom is a type of chest pain called angina. This pain is most often felt under the chest bone (breast bone) or left side of the chest. The pain is referred to as:

  • Constricting.

  • Lasts from 5 to 30 minutes.

The person might pass out.

Unlike angina that is brought on by hardening of the coronary arteries, chest pain and shortness of breath due to coronary artery spasm are frequently not provide when you walk or exercise.

Exams and Tests

Tests to detect coronary artery convulsion may consist of:

  • Coronary angiography.
