What is the difference in the treatment between a STEMI and NSTEMI?
A STEMI or ST-elevation myocardial infarction is caused by a sudden complete (100 percent) blockage of a heart artery (coronary artery). A non-STEMI is usually caused by a severely narrowed artery but the artery is usually not completely blocked. The diagnosis is initially made by an electrocardiogram (ECG or EKG).
What is the difference between NSTEMI and STEMI?
- Myocarditis
- Pericarditis
- Pulmonary embolism
- Left ventricular aneurysm
- Prinzmetal angina
- Anxiety Disorder
- Aortic Stenosis
- Hypertensive emergency
Is a NSTEMI the same thing as unstable angina?
This underlines the importance of prompt diagnosis and intervention. NSTEMI and unstable angina are different in one fundamental aspect: NSTEMI is by definition an acute myocardial infarction, whereas unstable angina is not an infarction. Unstable angina is only diagnosed if there are no evidence of myocardial infarction (necrosis).
How to diagnose a NSTEMI?
- Symptoms of acute myocardial ischemia such as typical chest pain.
- New ischemic ECG changes.
- Development of pathological Q waves.
- Imaging evidence of new loss of viable myocardium, significant reversible perfusion defect on nuclear imaging, or new regional wall motion abnormality in a pattern consistent with an ischemic etiology.
Is NSTEMI heart attack?
A non-ST-elevation myocardial infarction (NSTEMI) is a type of heart attack that usually happens when your heart's need for oxygen can't be met. This condition gets its name because it doesn't have an easily identifiable electrical pattern (ST elevation) like the other main types of heart attacks.
What is the difference between an NSTEMI and a STEMI?
NSTEMI is caused by a block in a minor artery or a partial obstruction in a major artery. STEMI occurs when a ruptured plaque blocks a major artery completely.
What is a typical cause of NSTEMI?
The etiology of NSTEMI varies as there are several potential causes. These include tobacco abuse, lack of physical activity, high blood pressure, high cholesterol, diabetes, obesity, and family history.
What is the treatment for NSTEMI?
Drug treatment is used for those who are low risk who've had an NSTEMI. Medications that may be given include anticoagulants, antiplatelets, beta-blockers, nitrates, statins, angiotensin-converting-enzyme (ACE) inhibitors, or angiotensin receptor blockers (ARBs).
Is NSTEMI worse than STEMI?
STEMI vs NSTEMI – Which is Worse? The bottom line is that both are just as bad. STEMI is seen as more of an immediate emergency because there is a known total occlusion of a heart vessel that needs opening back up urgently. In terms of long-term outcomes, they have equal health implications.
Can NSTEMI cause heart failure?
Coronary artery disease, including the acute coronary syndromes (ACS) of unstable angina, non–ST-segment elevation myocardial infarction (NSTEMI) and ST-segment elevation myocardial infarction (STEMI), is the most common cause of heart failure (HF).
How long does it take to recover from a NSTEMI?
Most patients stay in the hospital for about a week or less. Upon returning home, you will need rest and relaxation. A return to all of your normal activities, including work, may take a few weeks to 2 or 3 months, depending on your condition. A full recovery is defined as a return to normal activities.
How is NSTEMI diagnosed?
NSTEMI heart attacks are diagnosed through the combination of a blood test and an electrocardiogram (ECG). Doctors use the blood test to look for indications of NSTEMI, such as higher than usual levels of creatine kinase-myocardial band (CK-MB), troponin I, and troponin T.
What is the prognosis for NSTEMI?
The five-year survival rate for NSTEMI patients was 51%, 42% among women and 57% among men. The five-year survival rate for STEMI patients was 77%, 68% among women and 80% among men. Five year age-adjusted survival rates were higher for STEMI than NSTEMI (logrank: p <0.01).
How do you identify an NSTEMI on an ECG?
Definition. Non-ST-elevation myocardial infarction (NSTEMI) is an acute ischemic event causing myocyte necrosis. The initial ECG may show ischemic changes such as ST depressions, T-wave inversions, or transient ST elevations; however, it may also be normal or show nonspecific changes.
Is NSTEMI unstable angina?
Non-ST-elevation myocardial infarction (NSTEMI), ST-elevation MI (STEMI), and unstable angina are the three traditional types of ACS. However, the widespread use of the high-sensitivity troponin test has changed the diagnosis of unstable angina to NSTEMI in almost all patients formerly diagnosed with unstable angina.
Does NSTEMI have elevated troponin?
However, an elevated troponin along with other appropriate clinical and laboratory evidence raises the probability that the diagnosis is NSTEMI. The higher the troponin value, the greater the probability that the final diagnosis will be MI.

Overview
A non-ST-elevation myocardial infarction is a type of heart attack that happens when a part of your heart is not getting enough oxygen. This condition gets its name because — unlike an ST-elevation myocardial infarction (STEMI heart attack) — it doesn’t cause a very specific, recognizable change to your heart’s electrical activity.
Diagnosis and Tests
A physician diagnoses an NSTEMI based on a combination of tests and other types of information gathering. Combining these methods is especially important because an NSTEMI is more likely to have symptoms or test results that are less specific than those seen with STEMI or other conditions.
Prevention
There are several things you can do to help prevent a heart attack, or at least delay one. One key thing is to schedule a physical (also called a checkup or wellness visit) with your primary care provider.
Living With
Many of the tips listed above under the Prevention section are also good for helping take care of yourself after a heart attack. Focusing on diet and exercise, maintaining a healthy weight, managing other health conditions and going to your follow-up visits are all very important steps.
Why is NSTEMI called NSTEMI?
During a heart attack, the ST-segment is raised. As such, NSTEMI gets its name because there is no evidence of ST-segment elevation. Because NSTEMI causes damage to the heart muscle, doctors still consider it a heart attack (some might say a "mild" heart attack).
What is NSTEMI treatment?
Emergency Treatment. NSTEMI treatment is identical to that for unstable angina. If you have cardiac symptoms (chest tightness, clamminess of the skin, shooting pains in the left arm, etc.), the doctor will begin intensive therapy to stabilize the heart and prevent further damage.
What are the criteria for a TIMI score?
The TIMI score assesses whether the person has any of the following risk factors: 1 Age 65 years or older 2 Presence of at least three risk factors for coronary heart disease 3 Prior coronary blockage of greater than 50% 4 ST-segment deviation on the admission ECG 5 At least two angina episodes in the past 24 hours 6 Elevated cardiac enzymes 7 Use of aspirin within the past seven days
What is a TIMI score?
Many cardiologists will use a TIMI (thro mbosis in myocard ial infarction) score to determine the likely outcome for the individual. The TIMI score assesses whether the person has any of the following risk factors: Age 65 years or older. Presence of at least three risk factors for coronary heart disease.
Can you use aspirin for a TIMI score of 0-2?
Elevated cardiac enzymes. Use of aspirin within the past seven days. If you have two risk factors or less (TIMI score 0-2), you may not need further intervention. If the score is higher, the cardiologist may want to perform a cardiac catheterization with angioplasty and stenting.
Does NSTEMI cause STEMI?
NSTEMI rarely leads to STEMI because they have different mechanisms of action. NSTEMI is more likely in people with diffuse coronary disease, who often have collateral vessel development. People with STEMI are less likely to have that sort of diffuse disease or collateral vessel development.
What is a NSTEMI?
NSTEMI or non-ST segment elevation myocardial infarction is a type of heart attack. An NSTEMI differs from a STEMI, which is the most common type of heart attack, by causing less damage to a person’s heart. An electrocardiogram or ECG that displays each heartbeat as a waveform is used to determine if an NSTEMI or a STEMI has occurred in a person.
How to reduce the risk of NSTEMI?
Steps people can take to reduce their risk of an NSTEMI include: having a healthy, nutritious, and balanced diet, including fruits, vegetables, healthy fats, and whole grains.
What are the symptoms of NSTEMI?
A person should call 911 immediately if they experience any of them. The following are symptoms of an NSTEMI: feeling short of breath. pressure, tightness, or discomfort in the chest.
Is UA more severe than NSTEMI?
It differs from stable angina, which can occur more frequently and without exertion. UA may also be more severe with more significant damage being done. Symptoms of unstable angina can feel similar to NSTEMI and may include: chest pain that can occur when resting, sleeping, and without exertion.
Is NSTEMI a heart attack?
Heart attacks are often frightening and are considered serious. This applies to an NSTEMI even though it is considered a less severe type of heart attack than a STEMI. Medication and, in some cases, surgery, may be required to treat an NSTEMI.
What is NSTEMI in medical terms?
An NSTEMI is a type of acute coronary syndrome (ACS). ACS happens when your heart needs more oxygen than it's getting. Since blood carries oxygen to your heart, anything that limits the flow of blood can cause an NSTEMI. These causes can include:
What is non ST segment elevation?
What Is a Non-ST Segment Elevation Myocardial Infarction? A non-ST segment elevation myocardial infarction, also called an NSTEMI or a non-STEMI, is a type of heart attack. While it's less damaging to your heart than a STEMI, it's still a serious condition that needs immediate diagnosis and treatment.
What does ST-segment change mean?
ST-segment change (based on your EKG) If you had heart failure when you got to the hospital. If your blood tests show your heart is stressed (cardiac biomarkers) Based on your GRACE risk score, you will either be low, medium, or high risk. Low risk.
How to diagnose NSTEMI?
Diagnosis. NSTEMI heart attacks are diagnosed through the combination of a blood test and an electrocardiogram (ECG). Doctors use the blood test to look for indications of NSTEMI, such as higher than usual levels of creatine kinase-myocardial band (CK-MB), troponin I, and troponin T.
How to tell if you have NSTEMI?
Symptoms of NSTEMI: Difficulty or trouble breathing. Heaviness or pressure in your chest. Tension or tightness in your che st. Discomfort in your che st. Pain or irritation in your neck. Pain or irritation in your stomach. Pain or irritation in your jaw. Pain or irritation in your back.
What is a non ST elevation heart attack?
What is an NSTEMI? A Non-ST-Elevation Myocardial Infarction is a type of heart attack, often referred to as NSTEMI or a non-STEMI. In medical terminology, a heart attack is a myocardial infarction. An NSTEMI is a less severe form of heart attack than the STEMI because it inflicts less damage to the heart. However, both are heart attacks and require ...
Is NSTEMI a heart attack?
NSTEMI produces several symptoms similar to other conditions. Any symptoms associated with a heart attack are serious. Anyone experiencing any of the NTEMI symptoms should contact 911 or visit an emergency room immediately, regardless of severity. With heart attacks, every minute counts.
Why does NSTEMI occur?
Finally, conditions relatively unrelated to the coronary arteries or myocardium itself such as hypotension, hypertension, tachycardia, aortic stenosis, and pulmonary embolism lead to NSTEMI because the increased oxygen demand cannot be met. [4][5] History and Physical.
When should beta blocker therapy be started for NSTEMI?
Beta-blocker therapy should be started within 24 hours after the presentation in patients who do not have a contraindication.
Is a ST elevation considered a STEMI?
A normal ECG does not exclude ACS and NSTEMI. ST-elevation or anterior ST depression should be considered a STEMI until proven otherwise and treated as such.
How effective is aspirin for NSTEMI?
Aspirin has an astonishing effect in NSTEMI and unstable angina: it reduces 30-days mortality by 50%. Aspirin is also effective in preventing re-infarction beyond 30-days and must never be discontinued without careful consideration. The optimal dose of aspirin is unknown but studies show that maintenance doses between 80 mg and 1500 mg are equally effective; hence, 80 mg is preferred as it minimizes the risk of gastrointestinal bleedings. Similarly, loading doses greater than 320 mg do not confer any additional benefit, which is why a loading dose of 320 mg is recommended.
How is unstable angina different from NSTEMI?
NSTEMI and unstable angina are different in one fundamental aspect: NSTEMI is by definition an acute myocardial infarction, whereas unstable angina is not an infarction. Unstable angina is only diagnosed if there are no evidence of myocardial infarction (necrosis). However, unstable angina is considered an acute coronary syndrome because it is an imminent precursor to myocardial infarction. Approximately 50% of patients with unstable angina progress to myocardial infarction within 30 days if left untreated. Moreover, the pathophysiology of NSTEMI and unstable angina is very similar: both are due to partial (incomplete) coronary artery occlusions, which implies that there remains residual blood flow in the artery. Moreover, management of NSTEMI and unstable angina is virtually equal and this explains why NSTEMI and unstable angina have traditionally been grouped together.
What causes NSTEMI and unstable angina?
This is explained by the fact that NSTEMI and unstable angina are caused by partial (incomplete) coronary artery occlusions; a partial occlusion results in a reduction of coronary blood flow and this causes subendocardial ischemia (i.e ischemia that only affects the subendocardium).
Can NSTE-ACS show normal ECG?
Most patients with normal ECG on arrival will develop some ECG changes during the process. Moreover, a normal ECG on arrival does not rule out myocardial ische mia/infarction ; some infarctions are too small to engender ECG changes and others may be dynamic over time and initially present without ECG changes.
Can NSTEMI cause cardiac arrest?
As in patients with STEMI, those with NSTEMI and unstable angina are at considerable risk of developing life-threatening ventricular arrhythmias ( ventricular tachycardia, ventricular fibrillation) and subsequently cardiac arrest.
What is a STEMI?
A STEMI is an ST-Segment Elevation Myocardial Infarction – the worst type of heart attack. This type of heart attack shows up on the 12-lead EKG. An NSTEMI (or Non-STEMI) does not have any ST elevation on the ECG, but may have ST/T wave changes in contiguous leads. Patients with STEMI usually present with acute chest pain and need to be sent to ...
What is the ACUTE MANAGEMENT OF STEMI?
STEMIs are true medical emergencies. The patient is at a high risk of significant conduction disturbances and arrhythmias including cardiac arrest. The longer you wait – the more heart cells will die, leading to worse cardiac outcomes as well as increasing the possibility of patient death.
How long does a STEMI last?
Hyperacute T waves are first seen, which are tall, peaked, and symmetric in at least 2 contiguous leads. These usually last only minutes to an hour max.
What is non ST segment elevation?
A Non-ST segment elevation myocardial infarction (NSTEMI) refers to a complete occlusion of a coronary artery that does not cause ST-segment elevation on the ECG. While some heart tissue dies, this is usually less extensive than a STEMI. The infarction is usually limited to the inner layer of the myocardial wall.
Is NSTEMI a heart attack?
As the name suggests, an NSTEMI does not have ST elevation seen on the ECG, but it is still a heart attack. An elevated and rising troponin leve l is associated with an NSTEMI. The ECG can be completely normal, or it can have nonspecific T wave changes or even ST depression in contiguous leads. Management of an NSTEMI is similar to ...
Is NSTEMI a STEMI?
Management of an NSTEMI is similar to a STEMI in terms of medication s. However, they are not given fibrinolytic and are not emergently brought to the cath lab. They may or may not get a cardiac cath during their hospital stay. Instead, medication therapy is maximized like the ones described above.
