title: The influence of coronary angioplasty of the infarct-dependent artery on systolic and diastolic function of the left ventricle.
abstract: The target of research is to compare the changes of systolic and diastolic functions of the left ventricle in patients with at least one month infarction after infarct-dependent artery recanalization through elective stenting. The group of 60 patients was selected, 47 men and 13 women, who underwent hospitalization in Central Hospital of Oilworkers in 2006-2007. The investigation was conducted on 30 patients (24 men and 6 women), who underwent elective stenting of LAD. The control group was composed of 30 patients (23 men and 7 women) after anterior myocardial infarction without further stenting of infarct-dependent artery. The clinical diagnosis was confirmed by coronary ventriculography. The patients underwent the echocardiography the day before stenting. The "Sonoline G60 (Siemens, Germany)" machine with 2.5MHz probe has been used. The echocardiography was repeated after 7 days and 3, 6, 12 months after stent implantation. The standard parameters of systolic and diastolic function of the left ventricle were identified during investigation. The statistical processing was delivered through PC with Excel program set. All data are presented in (M+/-m), where the M--mean value, m--standard mean fault. Comparison of the data was conducted with Student criterion. The results of treatment of patients with and without further stenting of infarct-dependent artery were compared. It was found that the stenting of infarct-dependent artery with standard therapy in patients after myocardial infarction has better impact on systolic function, than traditional medical therapy without further reperfusion. The stenting of infarct-dependent artery facilitates earlier improvement of the systolic and diastolic function of the left ventricle. The diastolic relaxation grade of the left ventricle after stenting of the left coronary artery is higher, than in patients without further revascularization.
