5-YEAR DYNAMICS OF FEATURES OF LEFT VENTRICULAR GEOMETRY IN PATIENTS WITH ISCHEMIC HEART DISEASE, DEPENDING ON TREATMENT TACTICS

. For a patient with coronary heart disease, recovery from myocardial revascularization is a complex process. Cardiac remodeling involves, after myocardial infarction, hypertrophy and dilation, resulting in impaired systolic-diastolic cardiac function, which is an additional risk factor for events. Prospective studies have shown a relationship between left ventricular size and the risk of cardiovascular events. Given this, there was a need to conduct our research. Purpose: To determine the prevalence of types of left ventricular geometry in patients with coronary heart disease, post-infarction cardiosclerosis, depending on therapeutic tactics: revascularization or conservative therapy for 60 months. Material and Methods: We examined 101 patients aged 58.6±4.2 years after myocardial revascularization (n = 71) and with conservative treatment only (n = 30), in whom the dynamics of echocardiographic parameters of the heart were evaluated for 5 years. The values ​​of remodeling myocardial mass index of the left ventricle and the relative thickness of the left ventricle were determined. Results and Discussion. At baseline, patients with concentric left ventricular hypertrophy (50.0%) and concentric remodeling (24.1%) predominated in the main group. Normal geometry in 14.8% and eccentric left ventricular hypertrophy were observed in 11.1%. In the comparison group, eccentric hypertrophy and concentric left ventricular remodeling were most commonly observed, 29.6% each, slightly less than 25.9% concentric hypertrophy, and the least was normal geometry (14.8%). After 60 months, patients with both groups did not experience normal left ventricular geometry and concentric remodeling. The concentric type (80.0%) was predominant in the main group, and the eccentric type (55.6%) in the comparison group. Conclusions. In patients with ischemic heart disease, postinfarction cardiosclerosis progresses in 5 year follow-up myocardial hypertrophy regardless of treatment. After revascularization, concentric left ventricular hypertrophy develops more often, whereas under conservative treatment, left ventricular eccentric hypertrophy is combined with systolic dysfunction and left atrial dilatation. After revascularization, an increase in the index was associated with an increase not only in body weight but also in changes in lipid profile and diastolic hypertension.
