How is a NSTEMI treated?
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).
When should PCI be performed?
Primary PCI should be done within 12 h from symptom onset, but even later if symptoms and ST-segment elevation are still there or have been stuttering.
What is the pathophysiology of ST-segment elevation?
ST segment elevation occurs because when the ventricle is at rest and therefore repolarized, the depolarized ischemic region generates electrical currents that are traveling away from the recording electrode; therefore, the baseline voltage prior to the QRS complex is depressed (red line before R wave).
What is an inferior MI?
An inferior wall MI — also known as IWMI, or inferior MI, or inferior ST segment elevation MI, or inferior STEMI — occurs when inferior myocardial tissue supplied by the right coronary artery, or RCA, is injured due to thrombosis of that vessel.
What is an NSTEMI mi?
Non-ST-elevation myocardial infarction (NSTEMI) is a type of [“heart attack”: link to new heart attack copy] involving partial blockage of one of the coronary arteries, causing reduced flow of oxygen-rich blood to the heart muscle.
What are the clinical signs and symptoms of a NSTEMI?
Symptoms of NSTEMI:
- Difficulty or trouble breathing.
- Heaviness or pressure in your chest.
- Tension or tightness in your chest.
- Discomfort in your chest.
- 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 inferior MI?
What causes ST elevation during MI?
An acute ST-elevation myocardial infarction occurs due to occlusion of one or more coronary arteries, causing transmural myocardial ischemia which in turn results in myocardial injury or necrosis.
