Predictive Value of Left Ventricular Diastolic Parameters on Type and Severity of Acute Coronary Syndrome

Abstract

Objectives: Coronary artery disease is the most common cardiovascular disease and is associated with high rates ofmortality and morbidity. The first impaired echocardiographic parameter in acute ischemia is diastolic function andsystolic dysfunction occurs later. In our study, we aimed to evaluate the predictive value of left ventricular diastolicparameters on type and severity of acute coronary syndromes.Methods: The study was prospectively performed by including 60 patients, who applied to our hospital with complaints of chest pain. 12 –lead ECG was performed for all patients. In order to make diastolic function staging, echocardiography was performed by a cardiologist. After receiving a diagnosis, patients were assessed with statistical analysesregarding their echocardiographic results.Results: According to echocardiography results of patients included in the study, normal function was observed in 25patients; impaired relaxation in 21; pseudonormal pattern in 7 and restrictive pattern in 7. According to the diagnosisof the patients, 26 patients were diagnosed with nonspecific chest pain. 27 patients were diagnosed as having NSTEMIand 7 patients were diagnosed as having STEMI. There was no correlation between the echocardiographic results of ourpatients and the diagnoses they have been received.Conclusion: Although diastolic parameters have many uses to evaluate diagnosis, prognosis and mortality of acutecoronary syndromes, there was no significant difference between the groups in our study. The most likely reason forthis is the inadequate number of patients in some groups.
