ABSTRACT
Background: Electrocardiography [ECG] is simple, quick and economic investigation for diagnosis of acute coronary syndrome. Its applicability in prediction of left main coronary artery/ 3 vessel coronary disease can be of very useful in saving precious time in the critical care of coronary patients
Objective: Electrocardiography changes as a predictor of left main coronary artery / 3 vesselcoronary disease in patients presenting with Non-ST segment elevation acute coronary syndrome
Methodology: This cross sectional study was executed from July 2014 to June 2015 at Isra University hospital Hyderabad taking 114 consecutive patients of age >/=20, of either gender, presenting with symptoms of Non-ST segment elevation MI or that showed ECG changes in lead aVR. Informed written consent for the study was taken from the immediate family members of patients. Approval from ethics review committee of Isra University was taken. Data analysis was done through SPSS. Descriptive statistics [Mean +/-standard deviation for continuous and frequencies and percentages for categorical variables] were expressed
Results: Patients' mean +/-SD age was 56.65 +/-15.44 years [Range: 20-89 years]. Male to female ratio was 3.4:1. More than a half [52%] of these patients had Left main [LM] / 3 vessels disease. About a quarter other [25%] had 2 vessels while [22%] had single vessel disease [P value <0.0001]. Patients having ST elevation in lead aVR, were associated with increased risk of developing LM / three vessels disease [P value <0.0001]
Conclusion: ST elevation in lead aVR and ST depression in leads II, III, and aVF can be practically used for evaluation left main / 3 vessel disease among NSTE-ACS patients
ABSTRACT
To compare the angiographic findings in patients with acute myocardial infarction [AMI] and compare it with diabetic and non-diabetic patients admitted in the cardiology department of LUHMS. Descriptive analytical study. Department of cardiology at Liaquat University of Medical and Health Sciences [LUMHS] Hospital, Hyderabad. Periods of 1[st] June 2012 to 31[st] July 2013. All patients with AMI and had diabetes mellitus and age eighteen or more than eighteen years both male and female were included after taking informed consent. Out of 297 patients diagnosed as AMI, 195 [65.65%] patients had acute ST elevation Myocardial Infarction and 102 [34.35%] patients had acute non ST elevation myocardial infarction. Among 297 patients, 190 [64%] patients were non-diabetic and 107 [36%] patients were diabetic. Diabetic patients were older, more often males, but prevalence of smoking was less marked. Coronary angiographic findings among patients with AMI and diabetics revealed three vessels disease. Older patients with male predominance presented with AMI and had diabetes mellitus were found to have three vessels disease in coronary angiography
