Influence of thioctic acid in patients with diabetes mellitus or newly diagnosed diabetes mellitus in combination with diabetic polyneuropathy after anterior septal Q wave myocardial infarction on the prevention of hypertrophy and structural myocardial remodeling

Abstract

BACKGROUND: Diabetes mellitus, one of the most common chronic diseases in the world, has a significant aggravating effect on the course of myocardial infarction. Thioctic acid affects the cardiovascular risks of diabetes mellitus and has a protective effect on ischemic myocardium. Human studies to support this effect have not been widely conducted.AIM: To confirm the possibility of using thioctic acid in patients with diabetes mellitus or newly diagnosed diabetes mellitus in combination with diabetic polyneuropathy who have had anterior septal Q wave myocardial infarction to prevent hypertrophy and myocardial remodeling.MATERIALS AND METHODS: The study involved patients with myocardial infarction and type 2 diabetes mellitus, newly diagnosed diabetes mellitus and diabetic polyneuropathy. From the obtained groups, by randomization, subgroups were allocated to which thioctic acid was prescribed at a dosage of 600 mg / day orally for 3 months. To determine the comparability of the groups, a standard set of stationary studies was carried out. At the initial stage and 12 months after the start of the study, the echocardiographic parameters of myocardial hypertrophy and remodeling were monitored.RESULTS: The study involved 125 people, 5 people were excluded due to the development of unwanted adverse reactions. The formed groups were comparable in terms of initial parameters. In the main subgroups, statistically significant dynamics of LV wall hypertrophy and myocardial remodeling were not revealed. In the control subgroup of patients with diabetes mellitus, an increase in the thickness of the IVS was noted by 0.67 mm [95% CI: 0.4–0.94, p = 0.021], LVTZ by 0.8 mm [95% CI: 0.43–1 , 27, p = 0.043], LVMI at 9.2 g / m2 [95% CI: 6.15–12.24, p = 0.05], LVMI at 17.8 g. [95% CI: 11.3–24.3, p = 0.011], an increase in the prevalence of concentric myocardial remodeling by 16.7% (p = 0.026). In the control subgroup of patients with newly diagnosed diabetes mellitus, an increase in the thickness of the IVS was noted by 0.83 mm 95% [CI: 0.43–1.23, p = 0.047], LVMI by 7.9 g / m2 [95% CI: 4 , 47–11.43, p = 0.033], LVM at 16.7 gr. [95% CI: 9.75–23.65, p = 0.023], an increase in the prevalence of concentric myocardial remodeling by 16.7% (p = 0.026). In the main subgroup of patients with diabetes mellitus, a decrease in LVMM by 3.33 g was noted. [95% CI: 1.94–4.72, p = 0.024], LVMI at 4.19 g / m2 [95% CI: 2.18–6.2, p = 0.047].CONCLUSION: The use of thioctic acid on the 3rd day from antero-septal Q wave myocardial infarction in patients with type 2 diabetes, newly diagnosed diabetes mellitus, in combination with diabetic polyneuropathy, at a dosage of 600 mg / day orally, prevents hypertrophy and myocardial remodeling, and also contributes to the positive dynamics of the structure of the ejection fraction.
