Abstract Background and Aims To evaluate the effectiveness of complex personalized treatment of patients with chronic coronary syndrome (CCS) with type 2 diabetes mellitus (T2DM). Method We observed patients with chronic stable angina pectoris III (FC) (Group I, 16) and CV IV FC (Group II, 18) with T2DM who underwent planned stenting of the coronary arteries (SCA). At baseline and after 3 and 6 months, we studied cholesterol, LDL cholesterol and HDL cholesterol, triglycerides (TG), ALT and AST, total bilirubin (TB), polymorphism of the CYP2C19 and 9p21 genes (rs 2383206 and rs 10757272), assessed myocardial viability (ECHOCG, MSCT), an ultrasound of the liver was performed. Against the background of basic therapy (antiplatelet agents, statins, beta blockers, ACE inhibitors), patients received a herbal hepatoprotector. Results Initial lipid parameters in patients with CCS and T2DM: cholesterol—6.9 mmol/l; LDL cholesterol –3.6; HDL cholesterol –1.1; TG –2.5 mmol/l. Parameters of global and regional systolic function were reduced. At the end of observation, lipid content: cholesterol—5.0; LDL cholesterol—2.3; HDL cholesterol –1.18; TG—1.61 mmol/l. Statins and antiplatelet agents were well tolerated, and there were no cases of withdrawal. Enzyme activity (ALT, AST), OB content were within normal values. The genetic studies carried out helped to select the most effective and safe doses of antiplatelet drugs and statins and significantly reduced the risk of complications and drug resistance. The hepatoprotector had a beneficial effect on the condition and function of the liver and improved the tolerability of medications. A personalized approach to the treatment of CCS was carried out taking into account the results of genetic testing with the selection of optimal doses of drugs. When the genotypes of CYP2C19*17 (rs 12248560) CC, ST and TT were distributed, the dose of antiplatelet agents was increased, and when the genotypes of the CYP2C19 gene (rs 4244285) GG, AG and AA were distributed, they were reduced. Assessment of myocardial viability, selection of doses of statins and antiplatelet agents according to individual characteristics, as well as a hepatoprotector increased the effectiveness and safety of treatment. SCA and basic treatment had an impact on the pathogenetic links of CCS, which is especially important in the treatment of patients with concomitant T2DM. Conclusion A personalized approach to the treatment of patients with CCS with T2DM who require SCA, taking into account the functional state and viability of the myocardium, the pharmacogenetic characteristics of the drugs, increases the effectiveness of revascularization, prevents the development of resistance, side effects and complications.
