The presence of diastolic and systolic dysfunction in patients with impaired relaxation filling pattern

Background Impaired relaxation filling pattern in the presence of preserved left ventricular ejection fraction is a common finding which is ascribed to early diastolic dysfunction. We thought to determine the distribution of various markers of systolic and diastolic dysfunction in these patients. Methods A total of 106 patients were included in this retrospective observational study. Diastolic dysfunction was defined using the American Society of Echocardiography recommendations (“50% rule”). The systolic dysfunction was evaluated by global longitudinal strain and circumferential strain. For further analysis, the patients were divided into the lower strain (lower tertile) and higher strain (upper tertiles) groups based on longitudinal strain. Results There were marked differences between the groups in essential echocardiographic parameters. Patients in the lower strain group were more likely to have definite diastolic dysfunction (23% vs 7%, P
