Abstract

Aim To study early manifestations of left ventricular (LV) and right ventricular (RV) myocardial remodeling in high-risk patients.Material and methods Intracardiac hemodynamics was studied by equilibrium radionuclide ventriculography (ERVG) in 83 patients (mean age, 61.1±8.9 years) with preserved LV ejection fraction according to echocardiography data, a body weight index (BWI) >25 kg /m2, obesity, and type 2 diabetes mellitus (DM2). Parameters of intracardiac hemodynamics were compared in patients with different degrees of obesity and DM2 durations in age groups of younger and older than 60 years.Results All patients had both LV and RV diastolic dysfunction. The diastolic dysfunction progressed with age and DM2 duration, primarily by the restrictive type. The increase in BWI, in contrast, was associated with increases in ventricular volumetric parameters. It was noted that specifically modifiable risk factors (obesity and DM2), but not the age, mostly facilitated the impairment of RV relaxation.Conclusion The strategy of normalizing the body weight and carbohydrate metabolism is priority in combatting the development and progression of chronic heart failure in high-risk group patients.
