What is low risk UA?

The AHCPR guidelines “Unstable Angina: Diagnosis and Management” identified low-risk UA patients as those without rest or nocturnal angina and with normal or unchanged ECGs.

What are the categories of unstable angina?

Five different although not mutually exclusive causes of unstable angina are now recognized. These are (1) a nonocclusive thrombus on a preexisting plaque, (2) dynamic obstruction, (3) progressive mechanical obstruction, (4) inflammation, and (5) secondary unstable angina.

What is the difference between ACS and MI?

Acute coronary syndrome is a term used to describe a range of conditions associated with sudden, reduced blood flow to the heart. One such condition is a heart attack (myocardial infarction) — when cell death results in damaged or destroyed heart tissue.

What is TIMI risk score?

The thrombolysis in myocardial infarction (TIMI) risk score is a tool used to predict the chances of having or dying from a heart event for people with: unstable angina, a heart condition that causes chest pain. non-ST-segment elevation myocardial infarction (NSTEMI), a type of heart attack.

What is the first line treatment for NSTEMI?

The authors recommend that aspirin still be regarded as the first line of therapy for patients with unstable angina/NSTEMI and should be administered as soon as possible after hospital presentation and maintained indefinitely as long as tolerated.

What are the signs of unstable angina?


  • Chest pain that you may also feel in the shoulder, arm, jaw, neck, back, or other area.
  • Discomfort that feels like tightness, squeezing, crushing, burning, choking, or aching.
  • Discomfort that occurs at rest and does not easily go away when you take medicine.
  • Shortness of breath.
  • Sweating.

Can ACS lead to MI?

Two types of MI that can be produced by ACS. ST-Elevation myocardial infarction (STEMI), so named because the “ST segment” on the ECG appears “elevated,” occurs when a coronary artery is completely blocked so that a large proportion of the heart muscle being supplied by that artery begins to die.

Can you have a Nstemi without CAD?

Patients with non-ST-segment elevation myocardial infarction (NSTEMI) without obstructive coronary artery disease (CAD) are often managed differently than those with obstructive CAD, therefore we aimed in this study to examine the long-term prognosis of patients with NSTEMI according to the degree of CAD on coronary …

How do you rule out ACS?

Diagnosis requires an electrocardiogram and a careful review for signs and symptoms of cardiac ischemia. In acute coronary syndrome, common electrocardiographic abnormalities include T-wave tenting or inversion, ST-segment elevation or depression (including J-point elevation in multiple leads), and pathologic Q waves.

What is the most common symptom of cardiac compromise?

Cardiac compromise refers to any kind of heart problem. Patients may complain of chest pain, flu-like symptoms, or dyspnea(difficulty breathing). The most common complaint is chest pain. The pain may radiate down an arm with the left arm more commonly involved.
