A STUDY IN MI PATIENTS TO CORELATE THE SITE INFARCTION BY ECG AND ESTIMATE LEFT VENTRICULAR EJECTION FRACTION BY ECG AND 2DECHO IN INDEX MEDICAL COLLEGE, HOSPITAL AND RESEARCH CENTER INDORE (M.P.)

Abstract

BACKGROUND: CHF is very common feature of ST elevation MI and at times need urgent management but without echocardiography ,clinical assessment may be incomplete hence some knowledge regarding CHF can be obtained from this equation in areas where echocardiography cannot be done at the time

DURATION: This Study Was conducted in IMCHRC from September 2020 to august 2021

METHODS: 500 patients of age groups of 25-70 yrs of both genders with ST elevation MI of any region of single episode, the site of infarction left ventricular ejection fraction were estimated in ‘Q’ wave infarction, Using the QRS scoring system of Palmeri and then correlated to the same byEchocardiography for localization of wall motion abnormalities and ejection fraction by standard method.

INCLUSION CRITERIA: Patients above 25 years of age and WHO criteria for diagnosis of acute MI are included

1. A History of ischemic type of chest pain
2. Evolutionary changes as obtained on serial ecg
3. A rise followed by subsequent fall in serum cardiac markers.

EXCLUSION CRITERIA : Non ST elevation MI ,Angina and angina equivalent, previous /old MI, History of MI ,Who refused consent , patient suffering from valvular heart disease ,congenital heart diseases.,pericardial disease, LVH, hemiblock, bundle branch blocks,complete heart block,previous cardiac surgeries

CONCLUSION :-

The location of MI was better elaborated on 2D Echo rather than  ECG

Bedside calculation of LVEF (pump function) can be done from  ECG in Q wave infarction, which fairly correlates with 2 D - Echo findings.

Anterior wall MI and Global MI patients had lower EF than inferior wall MI and should be managed aggressively .
