Invasive and Non-invasive Methods in Diagnosis of Cardiomyopathy
Abstract
ABSTRACT
Background: Electrocardiography and echocardiography are important non-invasive diagnostic tests in patients with cardiomyopathy, to confirm the presence of previous myocardial infarction and to assess left ventricular volume in diastole and systole and to estimate ejection fraction. Coronary angiography is invasive diagnostic method to assess severity of coronary stenosis and number of vessels affected
Objective: To know, which patients with cardiomyopathy need to be send for coronary angiography and might get benefit from revascularization
Methods: Fifty patients with cardiomyopathy underwent ECG, ECHO study to assess presence of previous myocardial infarction and to assess end-diastolic volume (EDV), end- systolic volume (ESV) and ejection fraction (EF%). Six patients underwent coronary angiography. Four of them underwent revascularization, three by percutaneous coronary intervention (PCI) and one by coronary artery bypass surgery (CABG).
Result: Myocardial infarction was present in 15(30%) of patients, 10(20%) had anterior myocardial infarction (AMI), 5(10%) had inferior myocardial infarction (IMI). Left bundle branch block (LBBB) was present in 10(20%). Echocardiographic findings were as fellow, end diastolic volume (EDV) 68.50±5.52, end systolic volume (ESV) 59.58±5.94, Interventricular septum (IVS) 6.64±1.24, left-ventricular posterior wall (LVPW) 6.96±1.23, ejection fraction (EF%) 35.42±4.69. Coronary angiography finding were as fellow, two patients had one vessel disease, two patients had 2-3 vessels disease and two had normal coronaries
Conclusion: This study demonstrates the importance of coronary angiography to refer patient with ischemic cardiomyopathy for revascularization.
