Presentation
A 55-year-old white woman presented to the emergency department with symptoms of dull aching shoulder and chest pain. [ncbi.nlm.nih.gov]
Clinical Presentation Patients who are experiencing an acute STEMI are classically described as presenting with pressure or crushing chest pain associated with shortness of breath, nausea/vomiting or diaphoresis. [cdemcurriculum.com]
The clinical presentation can be similar to an inferior wall MI (that is, GI symptoms can predominate). On an ECG, you see ST depression in the anterior leads (V1 and V2 big time). [dummies.com]
A 12-lead ECG should be performed on all patients presenting with the previously mentioned symptoms. [cathlabdigest.com]
Pathology of cardiac conduction as seen in 3-lead and 12-lead monitoring systems are presented in a practical manner to build confidence in this valuable diagnostic tool. [books.google.com]

- Fatigue
Patients may make statements such as “my bra is too tight” or compare the discomfort to a “burning sensation, toothache, or an elephant sitting on one’s chest.”3 Nausea and vomiting, or simply fatigue, may be the only complaint. [cathlabdigest.com]
In women, common signs and symptoms include unusual fatigue, sleep disturbances, shortness of breath, indigestion, and anxiety. Many women describe chest discomfort as aching, tightness, pressure, sharpness, burning, fullness, or tingling. [americannursetoday.com]

Women can also commonly experience back or neck pain, indigestion, heartburn, lightheadedness, shortness of breath, fatigue, nausea, or pain in the back of the jaw. [en.wikipedia.org]
- Asymptomatic
The ECG was recorded when the patient was asymptomatic. Observation of Q waves in leads II, III and aVF show OLD inferior wall myocadial infarction. [metealpaslan.com]
The patient was asymptomatic, blood pressure was 120 × 80 mm Hg, and there were no signs of hemodynamic instability. [cardiovascularultrasound.biomedcentral.com]
Small aneurysms are often asymptomatic but the presence of an aneurysm should be suspected in those with a history of MI who present with heart failure, ventricular arrhythmias or thromboembolism, particularly if the ECG has persistent ST elevation in [bsecho.org]

Because epigastric pain became worst, a new electrocardiogram was undertaken, revealing an 1 mm ST segment elevation in leads V2 to V5. [cardiovascularultrasound.biomedcentral.com]
Because symptoms of MI can be subtle, an ECG should be performed on any patient older than age 45 who is experiencing new epigastric pain or discomfort. The location of an MI depends on which coronary artery is occluded. [americannursetoday.com]

Hypotension : Hypotension may occur in various settings following acute MI. [brown.edu]
Mechanical Complications Hypotension and Ventricular Function Hypotension can occur for a number of reasons following an MI. [bsecho.org]
If they are treated with nitroglycerin, they may experience sudden and dramatic hypotension from vasodilation. [emsworld.com]
Nitrates should also be avoided because they can produce profound hypotension. [cathlabdigest.com]
Here are some other key points concerning an inferior wall MI: If you see a test question in which a person with an inferior wall MI presents with hypotension, there may be extension of the inferior wall MI to affect the right ventricle. [dummies.com]

T Wave
- T Wave Inversion
These feature are suggestive of posterior wall infarction, being the inverse of Q wave, ST elevation and T wave inversion which would have been recorded in a posterior lead. [cardiophile.org]

In 8 of these 22 patients, the infarct was silent in the sense that no ST segment elevation or Q waves were seen, although ST depressions or T wave inversions, or both, in all but one patient were compatible with subendocardial infarction. [ncbi.nlm.nih.gov]
Within a few hours, you can begin to see negative T waves or T wave inversion as the MI evolves. The T wave inversion can persist for months after the MI. [dummies.com]

Treatment
The emphasis on cardiac care in the field has evolved from dysrhythmia recognition and treatment only to recognition and treatment of an evolving MI. [emsworld.com]
[…] for a myocardial infarction that has received initial treatment, but is still less than 8 weeks old. [coder.aapc.com]
Final message Inferior STEMI generally lacks the vigor to cause extensive damage to myocardium in most situations .Further they respond better to treatment. [drsvenkatesan.com]
Treatments may include medicines and medical procedures such as coronary angioplasty. After a heart attack, cardiac rehabilitation and lifestyle changes can help you recover. [icdlist.com]
With proper diagnosis of the origin of the infarct and proper treatment, many co-morbidities and possibly mortality may be avoided. [cathlabdigest.com]
Prognosis
Anterior myocardial infarction carries the worst prognosis of all infarct locations, mostly due to larger infarct size. [lifeinthefastlane.com]
By definition, patients in quadrant 4 are in "cardiogenic shock" and have a poor prognosis, unless they have a correctable mechanical complication, or unless they are early into the course of their MI, and some of the ischemic myocardium is recovered [brown.edu]
FACTORS THAT DETERMINE PROGNOSIS IN ACUTE MYOCARDIAL INFARCTION (BOX 1) The immediate prognosis in patients with acute myocardial infarction is inversely related to the amount of myocardial reserves (total myocardial mass less the myocardium involved [pmj.bmj.com]
St-segment - elevation (> 1mm or more abouve baseline) is an indication of occlusive thrombus with poorer prognosis 14. reciprocal ST segment depression may occur in the leads facing the area opposite the site of injury 15. [quizlet.com]
Etiology
Differential diagnosis of ST elevations The most serious cause of ST elevations on ECG is a ST elevation MI, however there are other possible etiologies. As usual always consider the “worst first”. [cdemcurriculum.com]
