When do you use TIMI vs Heart score?
The HEART score predicts the 6-week risk of a major adverse cardiac event (MACE). TIMI score only predicts a 2-week all-cause mortality, new or recurrent MI, or severe recurrent ischemia requiring urgent revascularization.
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 does a HEART score of 3 mean?
Total HEART Score: risk category & recommended management strategy. 0-3: low risk, potential candidate for early discharge. 4-6: moderate risk, potential candidate for observation & further evaluation. 7-10: high risk, candidate for urgent or emergent intervention.
What is the HEART score for chest pain?
Scoring: 0 to 3 points = low risk (0.6% to 1.7% risk of major adverse cardiac events); 4 to 6 points = intermediate risk (16.6% risk); 7 to 10 points = high risk (50.1% risk)….HEART Score for Predicting Major Adverse Cardiac Events in Patients with Chest Pain.
| Element | Points |
|---|---|
| > 45 to < 65 | 1 |
| ≤ 45 | 0 |

What is class 3 angina?
Class III: Angina causes marked limitation of ordinary physical activity. It occurs when walking 1 to 2 blocks or climbing one flight of stairs (3 to 4 METs). Class IV: Angina occurs with any physical activity and may occur at rest (1 to 2 METs).
What are the 3 types of angina?
There are three types of angina:
- Stable angina is the most common type. It happens when the heart is working harder than usual.
- Unstable angina is the most dangerous. It does not follow a pattern and can happen without physical exertion.
- Variant angina is rare. It happens when you are resting.
What is Type 3 vessel?
Type III: The LAD and LCx arteries arise from the proximal part of the RCA. The Type III anomalies are very rare. CT angiogram can be very helpful in defining the anatomical malformation, acute angle take-off, the transmural course, and compression between the great arteries, which would require surgery.
How is TIMI flow measured?
TIMI frame count (TFC) measures the number of cine-angiographic frames to reach standardized distal landmarks, thus providing a quantitative assessment of epicardial flow.
What is a unstable angina?
Unstable angina is a condition in which your heart doesn’t get enough blood flow and oxygen. It may lead to a heart attack. Angina is a type of chest discomfort caused by poor blood flow through the blood vessels (coronary vessels) of the heart muscle (myocardium).
Is Class 3 angina unstable angina?
changes (class III, angina at rest, acute; C, postin- farction unstable angina). Unstable angina is a dynamic condition, and patients may initially be in one class and move to another as the underlying disease changes or as response to treatment occurs.
What are the four types of angina?
Types of Angina
- Stable angina.
- Unstable angina.
- Microvascular Angina.
- Vasospastic or variant angina.
