Peculiarities of myocardial remodeling in patients of different age groups 6 months after myocardial infarction

Abstract

Objective. To assess the nature of changes in the types of myocardial remodeling of the left ventricle in patients of middle, elderly and senile age with acute ST-segment elevation myocardial infarction within 6 months after successful revascularization. Materials and methods. The study included 132 patients with a diagnosis of acute ST-segment elevation myocardial infarction, in combination with arterial hypertension who were divided into 3 groups depending on age: middle-aged pa-tients (45- 59) – 48 people, elderly patients (60-74) – 44 people, senile patients (75-89) – 40 people. The type of left ventricular remodeling was assessed by determining the relative wall thickness and mass index of the left ventricular myocardium with doppler echocardiography in the first 12 hours after the onset of anginal syndrome, and after 6 months. All patients underwent percutaneous coronary intervention. Results. It was found that initially with the development of acute myocardial infarction, senile patients more often had eccentric left ventricular hypertrophy (in 25%) than patients of middle (6%) and elderly age (11%). After 6 months, in middle-aged patients, the type of remodeling eccentric hypertrophy increased to 14%, in the elderly – up to 23%, in senile patients – up to 50%. Conclusion. In patients who have undergone acute myocardial infarction against the background of traditional therapy and rehabilitation, there are changes in the types of left ventricular myocardial remodeling: eccentric hypertrophy increases in middle age up to 14%, in the elderly – up to 23%, in senile age – up to 50%.
