Abstract
Introduction. Evaluation of muscle strength of wrist flexors in patients with coronary heart disease can act as a predictor of total muscle strength and influence the prognosis for patients after a previous myocardial infarction, taking into account the rehabilitation program. The purpose of the study is comparison of clinical anamnestic characteristics of middle-aged men with coronary heart disease with comparable social status, physical activity and body mass index (BMI), depending on the presence of myocardial infarction as well as an assessment of muscle strength of the wrist flexors, bioelectrical impedance analysis and testosterone level. Material and Methods. The study included men at the age of 58.09±6.85 on average; living in rural areas who were clinically monitored by a cardiologist at the central district hospital: the main group included men 3 months after the first myocardial infarction, the comparison group — patients with stable coronary heart disease. Clinical anamnestic status of all patients was assessed; evaluation of muscle strength of wrist flexors by means of dynamometry, bioelectrical impedance analysis, testosterone test and SF-36 Survey were also carried out. Results. Middle-aged men (58.09±6.85 years old) living in rural areas who had a similar physical activity, a long anamnesis of hypertension 180 (72; 228) months, coronary heart disease (49.28±12.47 months), anamnesis of coronary artery bypass surgery — CABG (1.2±0.03 years) were more likely to have hereditary cardiovascular diseases (38 vs. 12% , p=0.05) and anamnesis of previous acute disturbance of cerebral circulation (16 vs. 2%, p=0.04) than patients after the first myocardial infarction. The 6-minute walk test was greater in men after the first myocardial infarction (457.07±46.44 vs. 416.64±51.58, р<0.05), they had higher indexes of physical — 70 (55; 80) scale against to 55 scale (25; 65, р<0.02) and social functioning — 75 (62.5; 100) vs. 62.5 (50; 75, p<0.05), energy level was 55 (50; 75) scale to 50 (45; 60) scale (p<0.05) and mental health 62 (52; 77) to 52 (52; 60) scale with (p<0.01). Regardless of the duration of IHD or the presence of the first myocardial infarction, middle-aged men with overweight who had the same correlation of muscle and adipose tissue and testosterone level showed comparable strength of wrist flexors, measured by means of a dynamometer.
Highlights
Цель настоящего исследования: сравнение клинико-анамнестических характеристик мужчин среднего возраста с ишемической болезнью сердца при сопоставимой физической активности и индексе массы тела, в зависимости от наличия инфаркта миокарда; а также оценка у них мышечной силы сгибателей кисти, биоимпедансометрии, уровня тестостерона, качества жизни по опроснику SF-36

Summary
Оценка мышечной силы сгибателей кисти у пациентов с ишемической болезнью сердца может служить предиктором общей мышечной силы и оказывать влияние на прогноз пациентов после перенесенного инфаркта миокарда с учетом программы реабилитации. Цель настоящего исследования: сравнение клинико-анамнестических характеристик мужчин среднего возраста с ишемической болезнью сердца при сопоставимой физической активности и индексе массы тела, в зависимости от наличия инфаркта миокарда; а также оценка у них мышечной силы сгибателей кисти, биоимпедансометрии, уровня тестостерона, качества жизни по опроснику SF-36. После впервые перенесенного инфаркта миокарда, группа сравнения — пациенты со стабильной ишемической болезнью сердца. Независимо от длительности ишемической болезни сердца и наличия впервые перенесенного инфаркта миокарда у мужчин среднего возраста с избыточной массой тела при одинаковом соотношении мышечной и жировой ткани и уровнях тестостерона имелась сопоставимая сила мышц сгибателей кисти, измеренная посредством динамометра. В. Клинико-анамнестическая характеристика мужчин среднего возраста с ишемической болезнью сердца в зависимости от длительности заболевания и наличия инфаркта миокарда.
