Title : A Cross sectional study on correlation between lead aVR positive finding in ECG of Acute Myocardial infarction patients with coronary angiographic findings admitted in a tertiary care centre

Abstract:

Aim: To find correlation between ECG changes of lead aVR positive in acute STEMI patients with coronary angiographic findings. To study the management pattern CAG coronary localisation , outcome of aVR positive STEMI patients .

Method: Patients  admitted with  acute myocardial infarction in INTENSIVE CORONARY CARE UNIT  at Chengalpattu Medical college  and Hospital during the period of Jan 2020 to JUNE 2022. Among this 140 patient included in our study based on inclusion and exclusion criteria.

Results: Among 140 patients mean age is 56.4 yrs, majority of the patients in 5^th and 6^th decade and male patients is 112(80%) and female patients 28(20%). ECHO shows majority of the patients had mild LV dysfunction 96 patients (68.5%).In CAG findings in contrast to aVR positive +NSTEMI, aVR positive STEMI patient majority of the patients had single vessel disease involving LAD 62(44.2%) followed by triple vessel disease 34(24.29%).

Conclusion: Analysis using different types of STEMI showed that this pattern was run mostly in anterior STEMI, aVR ST elevation denotes extensive coronary artery disease in left coronary system with more patient going for CABG
