There is reciprocal ST depression in the inferior leads (III and aVF). This pattern indicates an
extensive infarction involving the anterior and lateral walls of the left ventricle
.
What does anterior STEMI mean?
An anterior STEMI is
the front wall of the heart, and the most serious
. A posterior STEMI is the back wall of the heart. An inferior STEMI is the bottom wall of the heart.
What is anterolateral infarction?
Myocardial infarction in which
the anterior wall of the heart is involved
. Anterior wall myocardial infarction is often caused by occlusion of the left anterior descending coronary artery. It can be categorized as anteroseptal or anterolateral wall myocardial infarction. [ MESH:D056988 ]
How is anterior STEMI treated?
- The ideal treatment for all STEMIs is acute PCI or in some cases emergency CABGs.
- Primary PCI is preferred for reperfusion therapy in patients with STEMI if it can be performed within 90 minutes of first medical contact.
Is anterior myocardial infarction serious?
Anterior myocardial infarction (AMI) is a common heart disease associated with
significant mortality and morbidity
. Advancement in diagnosis and treatment options have led to a favorable outcome.
What is the best treatment for myocardial infarction?
All patients with a suspected myocardial infarction should be given
aspirin
. It is a powerful antiplatelet drug, with a rapid effect, which reduces mortality by 20%. Aspirin, 150-300 mg, should be swallowed as early as possible.
What causes anterolateral infarct?
Anterolateral infarcts result from
the occlusion of the left main coronary artery
, and changes appear in leads V5, V6, I, aVL, and sometimes V4. A true anterior infarct doesn’t involve the septum or the lateral wall and causes abnormal Q waves or ST-segment elevation in leads V2 through V4.
How long does a STEMI procedure take?
These hospitals have an average door-to-balloon time of
60 minutes
, well below the national average of 90 minutes. It is important for patients to go to a hospital with a cardiac catheterization lab so their artery can be opened up right away with a coronary angioplasty.
How long can you live after a STEMI?
After adjusting for baseline differences in age, sex, length of stay, comorbidities, hospital clinical complications, and physiologic variables, patients with STEMI were significantly more likely to have survived at
3 months
(OR 1.38; 95% CI 1.01–1.87), 1 year (OR 1.38; 95% CI 1.09–1.74), and 2 years (OR 1.53; 95% CI …
What are the signs and symptoms of a STEMI?
- Shortness of breath.
- Fatigue.
- Dizziness or lightheadedness.
- A cold sweat.
- Nausea and vomiting.
How do you avoid STEMI?
STEMI = ST-segment elevation. PCI = percutaneous coronary intervention. Most patients will need
dual antiplatelet therapy (DAPT)
for 12 months, an angiotensin-converting enzyme inhibitor (ACEI), a beta-blocker, and a statin, all of which have been shown to reduce the risk of coronary death.
Do you start heparin for STEMI?
Heparin should not be considered as routine therapy for ACS
and STEMI. Based on lack of clear benefit in the literature, it is not unreasonable to withhold heparin for both ACS and STEMI patients, especially in patients who are at moderate or high risk for bleeding complications.
When do you give TPA STEMI?
FDA-approved indications for alteplase include pulmonary embolism, myocardial infarction with ST-segment elevation (STEMI), ischemic stroke when given
within 3 hours of the start of symptoms
, and re-establishment of patency in occluded intravenous (IV) catheters.
Which artery is blocked in stemi?
An STEMI is the most serious type of heart attack where there is a long interruption to the blood supply. This is caused by a total blockage of
the coronary artery
, which can cause extensive damage to a large area of the heart.
What causes anterior myocardial infarction?
An anterior myocardial infarction results from
occlusion of the left anterior descending coronary artery
. This can cause an ST elevation myocardial infarction or a non-ST segment elevation myocardial infarction.
How do you identify a myocardial infarction on an ECG?
One of the most significant findings of myocardial infarction is
the presence of ST segment elevation
. The ST segment is the part of the ECG tracing that starts at the end of the S wave and ends at the beginning of the T wave. The point where the end of the Q wave and the ST segment meet is called the J point.
