Aspects of diagnosis, difficulties in the diagnosis and optimal therapeutic strategies in patient with hypertrophic cardiomyopathy and comorbid conditions such as arterial hypertension, ischemic heart disease, dyslipidemia, diabetes mellitus type 2, stenosis of the left renal artery, obesity are reviewed on the example of clinical case. Hypertrophic cardiomyopathy combined with multimorbidity conditions requires a high-quality medical management, where the main goal is to improve the quality and duration of patient's life. This goal is being achieved by optimizing patient's lifestyle and assigning only the minimum amount of medications. Necessity of careful diagnosis of hypertrophic cardiomyopathy, evaluation of the risk of sudden death and search of optimal treatment in patients with multimorbidity pathology are demonstrated in clinical case.

INTRODUCTION
Semi-centennial history of the study of the problem of hypertrophic cardiomyopathy (HCM) reflects the evolution of knowledge in the field of etiology, pathogenesis and clinical course, treatment options of this disease, diagnosis and prognosis.
Hypertrophic cardiomyopathy (HCM) is an autosomal dominant genetic disorder characterized by massive (over 1,5 cm) left ventricular hypertrophy (LVH), and/or in rare cases, the right ventricle, the most commonly observed pattern is asymmetrical thickening of the anterior interventricular septum (IVS). These features can cause dynamic obstruction of the left ventricular outflow tract, diastolic dysfunction, myocardial ischemia, and an increased risk of developing severe, life-threatening supraventricular and ventricular tachyarrhythmia and sudden death [ 1-2].
Multimorbidity is the combination of multiple chronic or acute diseases and medical conditions in one person. Multimorbidity is the hallmark of an older age, it individualizes clinical picture of HCM, and requires an adequate diagnostic and therapeutic strategies [3-4].
Medical management of such patients with multimorbidity in the cardiology clinic has not been studied enough, which is shown in the given clinical case.

RECOMMENDATIONS
1. Lifestyle modification: lipid-lowering diet with restriction of refined carbohydrates, increase of the intake of vegetables and fruits, restriction of consumption of table salt, water consumption amounts at the rate of 20 mL/kg in the winter and up to 30 mL/kg in the summer under the control of body weight; limit excessive exercise, allowed fresh air, swimming [5-6].
2. Drug therapy: Nebivolol is 5 mg in the morning (under the control of heart rate and blood pressure), Lisinopril - 10 mg in the evening, Acetylsalicylic acid - 100 mg 1 time per day, Rosuvastatin 10 mg 1 time per day for a long time, Metformin - 1000 mg, Glimepirid - 2 mg [7-12].
CONCLUSIONS
Hypertrophic cardiomyopathy in older age may be associated and combined with other diseases.
In this clinical case, it was combined with arterial hypertension, ischemic heart disease, dyslipidemia, diabetes mellitus, stenosis of the left renal artery, obesity. This combination requires a high-quality of medical management in which the goal of improving the quality and duration of life of the patient is achieved by modification of lifestyle and the minimum medical assignments when polypharmacy is not permitted [13-14].
However, in this clinical case, to confirm the diagnosis of hypertrophic cardiomyopathy, genetic testing is needed.
Thus, the strategy of therapeutic interventions in HCM is complex and involves an individual analysis of the complex of clinical, anamnestic, hemodynamic variables, as well as results of genetic diagnosis, assessment of risk of sudden death, characteristics of the disease, and effectiveness of treatment options.
