Scentific article

It was analyzed 103 clinical cases of secondary dilated cardiomyopathies. Among them were 84 men and 19 women, average age 61,8±1,2 years. All patients were analyzed by complaints, anamnesis of disease and life, performed electrocardiographic and echocardiographic examination. In order differential diagnosis of ischemic heart disease was conducted or coronary multidetector computed tomography coronary angiography, in 45.63% of patients had a history of occupational hazards identified. In 57.45% of them, this factor has been the sole cause of the disease; in 46.81% of cases of occupational hazard combined with alcohol abuse; while 25.53% – with CHD. In 59.57% of patients with a history of occupational hazards in the echocardiographic examination was found dilatation of the left ventricle, to 34.04% – dilatation of both ventricles and only 6.38% of cases diagnosed dilatation of the right ventricle. Also, the article describes the clinical case dilated cardiomyopathy in patients with a history in which was found a professional hazard. 67-years-old women was hospitalized with complaints of shortness of breath at rest, which was exacerbated by light exercise and lying down, discomfort in the heart, swelling in the lower extremities, palpitations and severe general weakness. She has been ill for the last 15 years. Initially, the patient was diagnosed with coronary heart disease, post-infarction cardiosclerosis, hypertension stage 3, grade 2, the risk is very high, chronic heart failure stage IIA, functional class III according to NYHA with reduced systolic function of the left ventricle. For 5 years, the patient was treated regularly in the hospital, and for the last 2 years, due to the onset of asthma attacks, she was admitted to the hospital urgently. She has been suffering from hypertension for the last 10 years and has been taking ACE inhibitors regularly. She worked as a seamstress for 35 years. At the same time, she noted the expressed dustiness of a working zone by particles of freshly dyed fabrics. Alcohol was not consumed. Upon admission to the hospital, the patient was moderate. There are signs of cardiac asthma. Coronary angiography did not reveal significant hemodynamic changes and MRI showed no scarring with delayed contrast, as a result of which the diagnosis was denied.
