Assessment of left ventricular function in former myocardial infarction patients by using radionuclide ventriculography

ABSTRACT

38 participants of study were divided into two groups. There were 28 subjects (25 males, 3 females) in case group, who had former myocardial infarction (MI) and history of MI. The mean age of case group was 62.5+/-7.4 years. 10 healthy subjects were involved in the control group. It was found that radionuclide ventriculography is a reliable explorative method for evaluation of left ventricular function in the patients with former MI. Sensitivity, specificity and parameters of EFx% (40.3+/-14.0), PER (2.3+/-0.7), 1/3ER (1.9+/-0.8) all decreased significantly in comparison with those of the control group. Left ventricular dysfunction on ventriculography related to site of MI and clinical level of heart failure. In the patient with former MI, there was relative closed correlation between EFx%, 1/3ER and grade of heart failure and PER had modest negative correlation with grade of heart failure
