Pre-infarction condition

Pre-infarction condition (synonyms: pre-infarction period, unstable angina, progressive angina) is an acute pathological condition characterized by paroxysmal chest pain (angina) associated with myocardial ischemia.

A pre-infarction condition occurs when there is a sudden disruption of the coronary circulation, most often due to the rupture of an atherosclerotic plaque in the coronary artery, followed by thrombosis. This leads to a decrease in blood flow to the myocardial area and the development of ischemia.

The main symptoms of a pre-infarction state:

  1. Paroxysmal chest pain (angina) lasting from 20 minutes to several hours. The pain is burning, squeezing in nature, radiating to the left arm, shoulder blade, and lower jaw.

  2. Increased heart rate and irregular heart rhythm.

  3. Increased blood pressure at the beginning of an attack.

  4. Possible cold sweat, weakness, shortness of breath.

A pre-infarction condition requires emergency hospitalization and treatment aimed at restoring coronary blood flow, as it can result in myocardial infarction. With timely treatment, the prognosis is favorable.



Dressler's syndrome has been described in patients with myocardial infarction who lack the typical features of a previous acute coronary syndrome and the characteristic symptoms of unstable angina or progressive angina. It is characterized by the development of an aneurysm or extensive ruptures of the interventricular septum and (or) the posterior wall of the left ventricle of the myocardium without ECG changes typical for infarction, but with persistent myocardial ischemia. Pathomorphologically, Dressler's syndrome is observed in patients without MI (usually young people) with signs of myocardial infarction on the ECG. This syndrome has no prognostic significance, but may require repeat coronary angiography.



Pre-infarction condition Terminology of pre-infarction condition Pre-infarction is a condition in which there is a sharp disruption of the heart with characteristic pain.

Pre-heart attack syndrome is a complex of symptoms including pain in the chest behind the sternum, acute shortness of breath and nausea. Clinical picture of pre-infarction condition Symptoms
