How is an anterior myocardial infarction treated?
How is an anterior myocardial infarction treated?
Beta blockers, glyceryl trinitrate and possibly ACE inhibitors work in this way. 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 is the preferred treatment for acute MI?
The pain of myocardial infarction is usually severe and requires potent opiate analgesia. Intravenous diamorphine 2.5–5 mg (repeated as necessary) is the drug of choice and is not only a powerful analgesic but also has a useful anxiolytic effect.
What treatment is indicated in the first 12 hours of myocardial infarction?
Alteplase, reteplase and streptokinase need to be given within 12 hours of symptom onset, ideally within one hour. Tenecteplase should be given as early as possible and usually within six hours of symptom onset. Bleeding complications are the main risks associated with thrombolysis.
What is a common treatment for MI?
The treatment of MI includes, aspirin tablets, and to dissolve arterial blockage injection of thrombolytic or clot dissolving drugs such as tissue plasminogen activator, streptokinase or urokinase in blood within 3 h of the onset of a heart attack.
Why is aspirin given for MI?
Long-term aspirin therapy reduces the yearly risk of serious vascular events (nonfatal myocardial infarction, nonfatal stroke, or vascular death), which corresponds to an absolute reduction of nonfatal events and to a smaller, but still definite, reduction in vascular death.
How is anterior wall MI diagnosed?
The ECG findings of an acute anterior myocardial infarction wall include: ST segment elevation in the anterior leads (V3 and V4) at the J point and sometimes in the septal or lateral leads, depending on the extent of the MI. This ST segment elevation is concave downward and frequently overwhelms the T wave.
What is anterior wall myocardial infarction?
An anterior wall myocardial infarction occurs when anterior myocardial tissue usually supplied by the left anterior descending coronary artery suffers injury due to lack of blood supply.
What is anterior myocardial infarction?
What is anterior mi and how can it be managed?
Anterior MI, like any other MI, benefits from early intervention and optimal medical therapy after reperfusion. Hospital teams involving emergency clinicians, hospitalists, cardiologists, and emergency and intensive care unit (ICU) nurses can work together to provide early intervention and reduce the time from medical contact to PCI.
What is included in the nursing care of an anterior-wall mi patient?
Nursing care of the anterior-wall MI patient in the coronary care and step-down units includes the following: assessing heart sounds for new murmurs, indicating valve involvement; muffled heart sounds, indicating cardiac tamponade; and pericardial friction rub, indicating pericarditis giving stool softeners daily to prevent straining.
What is an anterior wall occluded mi?
In an anterior-wall MI, the left anterior descending artery, which supplies blood to the large muscular anterior wall of the left ventricle and the anterior two-thirds of the intraventricular septum, becomes occluded. (See Linking MI location and ECG changes by clicking on the PDF icon above.)
What is the prognosis of an anterior-wall mi?
And among MIs, anterior-wall MIs are the most serious and have the worst prognosis. Typically, they are larger than other MIs, and they can result in significant ventricular wall-motion abnormalities and a significantly lower ejection fraction.
