Lateral Wall Myocardial Infarction

Myocardial Infarction (lateral Wall)


Presentation

  • CASE SUMMARY: A 55-year-old white woman presented to the emergency department with symptoms of dull aching shoulder and chest pain.[ncbi.nlm.nih.gov]
  • Inferior, posterior and lateral wall myocardial infarction Inferior, posterior and lateral wall myocardial infarction ST segment elevation and T wave inversion are present in II, III and aVF, the inferior leads.[cardiophile.org]
  • 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 most common cause of heart attacks is coronary artery disease (CAD). With CAD, there is a buildup of cholesterol and other material, called plaque, on their inner walls or the arteries. This is atherosclerosis. It can build up for years.[icdlist.com]
  • This scoring system is based on cardiac risk factors as well as known coronary artery disease. You can use the TIMI score to risk-stratify patients being admitted to the hospital.[dummies.com]
  • Globally, acute myocardial infarction is the leading cause of death for both men and women.1 In the United States, one in five deaths is attributed to coronary artery disease.2 What are the signs and symptoms of a patient presenting with acute myocardial[cathlabdigest.com]
  • Most deaths occur in the first 3 to 4 months and result from advanced atherosclerotic coronary artery disease (CAD). But early recognition of the signs and symptoms and prompt treatment can improve outcomes.[americannursetoday.com]

  • Horizontal STD in leads V 1 through V 3, occurring in a patient with the potential for acute ischemic heart disease, should lead one to consider the diagnosis of acute PMI and employ additional investigations such as posterior thorax ECG leads.[ahcmedia.com]
  • Left Bundle Branch Block(LBBB) : LBBB does signify underlying heart disease but may be new or a chronic change.[cdemcurriculum.com]
Heart Block
  • Complications may include a sudden onset of distal heart block (Mobitz type II second degree), complete heart block, or new onset bundle branch block, hypertension, and signs of left ventricular dysfunction such as congestive heart failure, pulmonary[cathlabdigest.com]
  • Heart Block and Bradycardia: In addition to the ST elevations on EKG one should also look for second or third degree heart block or bradycardia.[cdemcurriculum.com]
  • Bradycardia or heart block with anterior-wall MI is a poor prognostic sign.[americannursetoday.com]
Vascular Disease

Workup

Right Axis Deviation
  • axis deviation) Left anterior fascicular block (may see small q-waves in anterior chest leads) Acute pericarditis (the ST segment elevation may mimic acute transmural injury) Central nervous system disease (may mimic non-Q wave MI by causing diffuse[ecg.utah.edu]
Inferior Q Wave
  • Example #2: Old inferior Q-wave MI; note largest Q in lead III, next largest in aVF, and smallest in lead II (indicative of right coronary artery occlusion).[ecg.utah.edu]
Septal Q Wave
  • WPW preexcitation ( negative delta wave may mimic pathologic Q waves) IHSS (septal hypertrophy may make normal septal Q waves "fatter" thereby mimicking pathologic Q waves) LVH (may have QS pattern or poor R wave progression in leads V1-3) RVH (tall R[ecg.utah.edu]
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]
  • There is also a loss of general R wave progression across the precordial leads and there may be symmetric T wave inversion as well.[meds.queensu.ca]

  • 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]
  • 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]
  • 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]

Prognosis

  • Anterior myocardial infarction carries the worst prognosis of all infarct locations, mostly due to larger infarct size.[lifeinthefastlane.com]
  • Lateral extension of an anterior, inferior or posterior MI indicates a larger territory of myocardium at risk with consequent worse prognosis. How to recognise a lateral STEMI ST elevation in the lateral leads (I, aVL, V5-6).[lifeinthefastlane.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]
  • Right ventricular infarction as an independent predictor of prognosis after acute inferior myocardial infarction. N Engl J Med. 1993 Apr 8;328(14):981-8.[teikyo-cvs.com]
  • Lateral extension can indicate a larger area of tissue involvement and a consequently worse prognosis. The lateral leads are V4-6, I and aVL with reciprocal ST depressions present in III and aVF.[cdemcurriculum.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]

  • But if you do get quick treatment, you may be able to prevent or limit damage to the heart muscle. That's why it's important to know the symptoms of a heart attack and call 9-1-1 if you or someone else is having them.[icdlist.com]
  • For secondary prevention, beta-blocker therapy will continue after discharge because it decreases mortality after MI by 30%.[americannursetoday.com]
  • Early recanalization prevented development of Q waves in inferior leads. Only the negative T waves in leads III and aVF can be the evidence of an OLD inferior myocardial infarction. Leads III and aVF have rS complex.[metealpaslan.com]
  • As stated previously, the goal in the treatment of the patient presenting with acute myocardial infarction is reperfusion to the myocardium and prevention of co-morbidities.[cathlabdigest.com]
