What is Type 4C myocardial infarction?

Type 4C myocardial infarction (MI) is a special type of myocardial infarction related to restenosis without thrombosis. There is a lack of relevant data on this new classification of acute MI (AMI).

What is TIMI score used for?

The TIMI risk score was found to be predictive of the severity of the vascular disease, making it a powerful tool to predict the potential blood vessels of coronary circulation that could be involved.

How do you interpret TIMI risk score?

The TIMI score can range between one and seven. Scores from zero to two are low risk, three to five are intermediate risk, and scores six to seven are high risk. Each of the points on the scale can be understood as follows: If you get one point, you are at 5% risk for heart-related mortality.

What is cardiovascular risk stratification?

Cardiac risk stratification is a very broad topic but simply can be defined as an assessment used to evaluate a patient’s risk of developing cardiovascular disease (CVD) or the risk of a cardiac event occurring in noncardiac surgeries, also known as a perioperative risk assessment.

What are the 4 types of myocardial infarction?

ST segment elevation myocardial infarction (STEMI) non-ST segment elevation myocardial infarction (NSTEMI) coronary spasm, or unstable angina.

How do you classify myocardial infarction?

The classification distinguishes between type 1 myocardial infarction due to thrombosis of an atherosclerotic plaque and type 2 myocardial infarction due to myocardial oxygen supply-demand imbalance in the context of another acute illness.

What is a high risk TIMI score?

Event rates increased significantly as the TIMI risk score rose. Patients are considered to be at low risk with a score of 0 to 2, intermediate risk with a score of 3 to 4, and high risk with a score of 5 to 7.

What is TIMI score for stemi?

Baseline TIMI risk score for STEMI has 0 to 14 possible points. Whereas the baseline TIMI risk score for STEMI has 0 to 14 possible points, the dynamic TIMI risk score has a total of 0 to 29 possible points, with 0 to 15 points assigned based on in‐hospital events (Table 2).

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.

How do you risk stratify a patient?


Adjust risk levels as the patient’s situation changes or based on new information from staff or other sources. Reassess individual risk levels regularly as they tend to change over time. Make risk levels easy to find in the EHR.

What is a high Gupta score?

Patients at a high risk of myocardial infarction or cardiac arrest present a Gupta score above 1%. They will certainly need additional cardiac evaluation after surgery.

What is a type 5 myocardial infarction?

Purpose. A type 5 myocardial infarction is currently defined when troponin values >10 times the 99th percentile upper reference limit occur during the first 48 hours following coronary artery bypass grafting (CABG), rising from a normal baseline troponin value.

What is a Type 3 myocardial infarction?

The type 3 myocardial infarction was defined according to the Universal definition of myocardial infarction, that is, cardiac death with symptoms suggestive of myocardial ischemia and presumed new ischemic ECG changes or new left bundle branch block, but death occurring before blood samples could be obtained, before …

What are the stages of myocardial infarction?

The myocardial infarction process can be divided into 2 phases, an early evolving phase (the first 6 hours) and a later convalescent phase. An evolving infarction is associated with an occluded coronary artery; in most cases, a thrombotic occlusion occurs.

What does TIMI 3 flow mean?

The PAMI definition of TIMI 3 flow, “complete filling of the distal vessel by the third cardiac cycle,” when compared with the original definition, which is based on flow compared with the non-infarct-related artery,2 actually overestimates the number of patients who are deemed to have TIMI 3 flow by ≈10%.

What is a HEART score of 4?

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 a high risk HEART score?

HEART Score for Predicting Major Adverse Cardiac Events in Patients with 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).

What are risk stratification models?

Risk stratification (often called predictive modelling or predictive risk modelling) is used to predict future adverse events for individuals. These events, such as unplanned hospital admissions, are costly, undesirable, and potentially preventable.

What is the risk stratification process?

Risk stratification enables providers to identify the right level of care and services for distinct subgroups of patients. It is the process of assigning a risk status to patients, then using this information to direct care and improve overall health outcomes.

What is high risk stratification?

Risk stratification uses a mix of objective and subjective data to assign risk levels to patients. Practices can systematically use patient risk levels to make care management decisions, such as providing greater access and resources to patients in higher risk levels.

What is low risk stratification?

Low-risk. This group includes patients who are stable or healthy. These patients have minor conditions that can be easily managed. The care model for this group aims to keep them healthy and engaged in the health care system, without the use of unnecessary services. POPULATION HEALTH MANAGEMENT.

What is a Type 2 myocardial infarction?

Type 2 myocardial infarction (MI) is defined by a rise and fall of cardiac biomarkers and evidence of ischemia without unstable coronary artery disease (CAD), due to a mismatch in myocardial oxygen supply and demand. Myocardial injury is similar but does not meet clinical criteria for MI.

What are the 3 stages of myocardial infarction?

Acute myocardial infarction with rupture, gross. Acute myocardial infarction with rupture and tamponade, gross. Intermediate (healing) myocardial infarction (1 – 2 weeks), microscopic. Remote myocardial infarction (3 to 4 weeks), microscopic.

What is TIMI flow grade?

‘TIMI Grade Flow’ is a scoring system from 0-3 referring to levels of coronary blood flow assessed during percutaneous coronary angioplasty: TIMI 0 flow (no perfusion) complete blockage – absence of any antegrade flow (forward flow) beyond a coronary occlusion.

What is a good cardiac risk score?

Moderate risk – a score of between 10% and 15%, you have (as a minimum), a 1 in 10 chance of having a heart attack or stroke in the next five years, if nothing is changed. Low risk – a score under 10%, you have a less than 1 in 10 chance of having a heart attack or stroke in the next five years, if nothing is changed.
