Do you give Nitro inferior wall MI?
Nitroglycerin is also contraindicated in the setting of an inferior MI with right ventricular involvement because, in this specific situation, the heart is dependent on preload.
Can you give nitrates in inferior MI?
Thus, in the setting of an inferior AMI, a marked hypotensive response to nitrates suggests the presence of RV involvement. Moreover, hypotension after nitrate administration may be anticipated in patients with known RV infarction, and in such patients, nitrates should be administered carefully.
Do you give Nitro for inferior stemi?
Despite the lack of strong evidence, AHA warns that NTG should be used with caution (if at all) in patients with ECG evidence of inferior wall STEMI when one suspects right ventricular involvement [4]. However, when right ventricular infarction is confirmed, NTG is generally contraindicated [4].
What stemi do you not give Nitro?
2013 AHA/ACC STEMI Guidelines: “Nitrates should not be given to patients with hypotension, marked bradycardia or tachycardia, RV infarction, or 5’phosphodiesterase inhibitor use within the previous 24 to 48 hours.”
Which artery is blocked in inferior wall MI?
Inferior wall myocardial infarction (MI) occurs from a coronary artery occlusion with resultant decreased perfusion to that region of the myocardium. Unless there is timely treatment, this results in myocardial ischemia followed by infarction.
When is nitro contraindicated Michigan?
Nitroglycerin is contraindicated in patients that have reported allergic symptoms to the medication. [18] Known history of increased intracranial pressure, severe anemia, right-sided myocardial infarction, or hypersensitivity to nitroglycerin are contraindications to nitroglycerin therapy.
Why is nitro not given for right ventricular infarct?
The main goals of field treatment for patients with RVI are to maintain preload to the right ventricle, cardiac output, blood pressure, coronary artery filling pressures and prevent shock. Because nitroglycerin is a vasodilator, it is contraindicated as standard treatment, or must be given with extreme care.
What does nitroglycerin do for the heart?
It is used to treat angina symptoms, such as chest pain or pressure, that happens when there is not enough blood flowing to the heart. To improve blood flow to the heart, nitroglycerin opens up (dilates) the arteries in the heart (coronary arteries), which improves symptoms and reduces how hard the heart has to work.
What is inferior infarct?
Excerpt. Inferior wall myocardial infarction (MI) occurs from a coronary artery occlusion with resultant decreased perfusion to that region of the myocardium. Unless there is timely treatment, this results in myocardial ischemia followed by infarction.
Is inferior myocardial infarction serious?
Inferior myocardial infarctions have multiple potential complications and can be fatal. See the review on ST elevation myocardial infarction for more detail on complications of an inferior myocardial infarction and a detailed discussion on treatment.
What causes inferior MI?
Is additional nitroglycerin required for acute inferior wall mi?
Additional nitroglycerin is not required. Acute inferior wall MI with right ventricular (RV) involvement is diagnosed, and primary percutaneous coronary intervention (PCI) is scheduled. Figure 2 – This ECG with the precordial leads switched to the right side of the chest shows Q waves and ST elevation in V 4 R through V 6 R.
How to manage an inferior wall mi?
Managing an inferior wall MI requires an interprofessional team of nurses, physicians, a cardiac surgeon, and a cardiologist. These patients are prone to life-threatening complications and hence prevention is the best approach. At discharge, the patients should be educated by the nurse about the potential need for pacing in the future.
Is nitroglycerin safe in inferior ST elevation myocardial infarction?
Prehospital Nitroglycerin Safety in Inferior ST Elevation Myocardial Infarction Patients with inferior ST elevation myocardial infarction (STEMI), associated with right ventricular infarction, are thought to be at higher risk of developing hypotension when administered nitroglycerin (NTG).
What is inferior wall myocardial infarction (MI)?
Inferior wall myocardial infarction (MI) occurs from a coronary artery occlusion with resultant decreased perfusion to that region of the myocardium. Unless there is timely treatment, this results in myocardial ischemia followed by infarction. In most patients, the inferior myocardium is supplied by the right coronary artery.
