Findings of Electrocardiography and Echocardiography in Patients with Normal Coronary Angiogram

Abstract

The type of this study is experimental study, which done in Khartoum State in two centers of cardiac catheterization laboratories. Many doctors request coronary angiogram for patients with changes in electrocardiographic (ECG) or echocardiographic investigations and this procedure is an invasive, high cost and high risk procedure, and many of results are normal. The main objectives of this study are to determine the findings of ECG and echocardiography in cases of normal coronary angiograms and detect the accuracy of them in diagnosis of myocardial ischemia or infarction. The study was based on one hundred (100) patients with clinically diagnosed of myocardial infarction or ischemic heart disease, and were grouped according to gender, male (43) patients and female (57) patients and according to age (25 - 78) years old. (1) patient had an aged between (20-29) years, (8) patients had an aged between (30-39) years, (31) patients had an aged between (40-49) years, (24) patients had an aged between (50-59) years, (18) patients had an aged between (60-69) years, (18) patients had an aged between (70-79) years. It was concluded that the ECG had a positive findings in sixty five (65%) cases of study sample, and negative in thirty five (35%) cases of study sample. The echocardiography had a positive findings in forty five (45%) cases of study sample and negative in fifty five (55%) cases of study sample (echocardiography has a superior accuracy in detecting myocardial infarction and ischemia than an electrocardiography because of a computerized machine but operator playing a greater role in diagnosis the exact problem).
