What are the two major acute coronary syndromes?

The term acute coronary syndrome (ACS) refers to any group of clinical symptoms compatible with acute myocardial ischemia and includes unstable angina (UA), non—ST-segment elevation myocardial infarction (NSTEMI), and ST-segment elevation myocardial infarction (STEMI).

What are examples of acute coronary syndromes?

Acute coronary syndrome refers to a group of diseases in which blood flow to the heart is decreases. Some examples include ST-elevation myocardial infarction, non-ST elevation myocardial infarction, and unstable angina.

What are the types of acute myocardial infarction?

Acute MI includes both non-ST-segment-elevation myocardial infarction (NSTEMI) and ST-segment-elevation myocardial infarction (STEMI). Distinction between NSTEMI and STEMI is vital as treatment strategies are different for these two entities.

What is the difference between acute coronary syndrome and MI?

Acute coronary syndromes result from a sudden blockage in a coronary artery. This blockage causes unstable angina or a heart attack (myocardial infarction), depending on the location and amount of blockage. A heart attack is death of heart tissue due to lack of blood supply.

What are the 3 types of acute coronary syndrome?

The term acute coronary syndrome (ACS) is applied to patients in whom there is a suspicion or confirmation of acute myocardial ischemia or infarction. Non-ST-elevation myocardial infarction (NSTEMI), ST-elevation MI (STEMI), and unstable angina are the three traditional types of ACS.

What are the complications of acute coronary syndrome?

Possible Complications
  • Abnormal heart rhythms.
  • Death.
  • Heart attack.
  • Heart failure, which happens when the heart cannot pump enough blood.
  • Rupture of part of the heart muscle causing tamponade or severe valve leakage.
  • Stroke.

How is acute coronary syndrome diagnosed?

A blood test can show evidence that heart cells are dying. An electrocardiogram (ECG or EKG) can diagnose an acute coronary syndrome by measuring the heart’s electrical activity.

What is the pathophysiology of acute coronary syndrome?

Pathophysiology of ischaemia

The most common cause of ACS and sudden death is occlusion of a coronary vessel secondary to disruption of atherosclerotic plaque with subsequent thrombus formation.

What is the difference between angina and acute coronary syndrome?

Definition. Acute coronary syndrome encompasses unstable angina, non-ST elevation MI (new term for non-Q wave MI, often referred to as non-STEMI), and ST elevation MI (new term for Q wave MI, often referred to as STEMI).

Is acute coronary syndrome a diagnosis?

The information from these two tests — as well as your signs and symptoms — is used to make a primary diagnosis of acute coronary syndrome. Your doctor can use the information to determine whether your condition can be classified as a heart attack or unstable angina.

Is Stable angina acute coronary syndrome?

It may manifest insidiously as angina pectoris or as an acute coronary syndrome (ACS). Stable angina is a chest discomfort due to myocardial ischemia that is predictably reproducible at a certain level of exertion or emotional stress.

What is acute coronary syndrome NHS?

A heart attack is a form of acute coronary syndrome (ACS), where there is a significant blockage in the coronary arteries. The 3 main types of ACS include: ST segment elevation myocardial infarction (STEMI) non-ST segment elevation myocardial infarction (NSTEMI) unstable angina.

What are the complications of acute coronary syndrome?

Possible Complications
  • Abnormal heart rhythms.
  • Death.
  • Heart attack.
  • Heart failure, which happens when the heart cannot pump enough blood.
  • Rupture of part of the heart muscle causing tamponade or severe valve leakage.
  • Stroke.

What is the pathophysiology of ACS?

Pathophysiology of ischaemia

The most common cause of ACS and sudden death is occlusion of a coronary vessel secondary to disruption of atherosclerotic plaque with subsequent thrombus formation.
