Angiodistonicheskie syndromes ( cardiopsychoneurosis ) occupational origin
Occupational Diseases / / May 21, 2016
hemodynamic disturbances (neurogenic nature) occur in many occupational diseases and poisoning.Such violations therapists usually termed "cardiopsychoneurosis".There are three types of it: hypertonic, hypotonic and cardiac.However dyscirculatory phenomena observed in occupational diseases, do not fit into this scheme: blood pressure is sometimes different in some areas, at the same time can be observed and hypotension and hypertension, and hemodynamic abnormalities in different patients prevail in cerebral, cardiac or peripheral blood vessels.Therefore, professional pathology, the term "angiodistonichesky syndrome" often used with the unit to the cardiac, cerebral and peripheral shape.
Angiodistonicheskie syndromes occur in diseases caused by physical factors - vibration, noise, electromagnetic radio frequency waves, as well as many intoxications - heavy metals (mercury, lead, manganese), non-metals (fluoride), organic compounds (vinyl chloride, etc..), as well as in working with high nervous tension (
a marked polymorphism and complaints: headaches, mostly diffuse, with original paresthesias ( "something shimmers," "something crawling in the head"), nausea, vomiting.The special intensity and diversity of experiences observed in vibration disease, chronic intoxication by carbon monoxide: non-system dizziness, flashing dark or light spots before the eyes, blurred coordination disorder, a sense of "the fragility of the soil" under the feet, pain and paresthesias in the hands, whitening of the fingers, which is particularlyspecificity in vibration disease, intoxication vinyl chloride.Sleep disturbances, irritability or fatigue, lethargy.Among the complaints relating to the state of the heart, dominated by pain.
Already subjective sensations indicate the predominance dyscirculatory phenomena in the vessels of the brain, heart or peripheral vessels.Angiodistonicheskie phenomena occur predominantly combination (tserebrokardialny syndrome).
very characteristic intermittent autonomic-vascular paroxysms without proof of brain or focal cerebral disorders with transient phenomena of cerebrovascular insufficiency.Along with regional angiodistonicheskimi events (headache, fainting, etc.), Observed generalized vascular crises with severe diencephalic color.
predominant type of vascular hypertensive reactions;hypotonic type is much rarer.In hypertensive type seen much generalization and severity of vascular disorders with symptoms of coronary spasm, high lability of blood pressure, pulse rate, often low-grade fever.
specially conducted observations of over angiodistonicheskogo syndrome with hypertension toxic origin showed the possibility of development in the future of essential hypertension as the outcome of intoxication, its long-term effects.
Angiodistonicheskie phenomenon long held after the termination.Aggravation angiodistonicheskogo syndrome can be caused by a number of endogenous and exogenous moments (pregnancy, menopause, physical and mental fatigue, cooling, physical and mental trauma, infection, etc.).
angiodistonicheskih syndromes is complex and poorly understood.Conducted clinical and physiological studies have shown marked dynamic dysregulation of vascular tone with a predominance of hypertensive syndrome, asymmetry of hemodynamic parameters, local disorders in the various segments of the vascular system (vessels of all sizes), a violation of the functional properties of myocardial contractility of it.Regional cerebral hyper- and hypotension documented study retinal and temporal pressure.Under the influence of some factors (eg vibration) suffers more vascular system and others (eg, manganese) - heart.
Research electrolyte metabolism in vibration disease, intoxication, manganese and carbon monoxide showed that in all these forms there is an increase in extracellular potassium concentration and the associated decline in the last concentration gradient.Perhaps this circumstance is one of the causes of myocardial functional disability, cardiovascular and nerve cells.When vibration disease marked by shifts of almost all indicators of electrolyte metabolism, indicating a weakening of the adrenal mineralocorticoid activity.Significant disruption of cholesterol metabolism that characterize the condition of vessels: increased total cholesterol, cholesterol loosely bound and not bound to proteins, and a decrease in the ratio of phospholipids and cholesterol.The uniformity of the changes is a non-specific response to the impact of individual factors that affect the central nervous system.
Angiodistonicheskie condition develop gradually.The disease, especially in its early stages, has no specific pattern, so that the professional nature it is not detected in a timely manner, and it is treated as a general.There are cases when the true diagnosis is 2-3 years after the initial treatment of the patient to the doctor.The most frequent diagnostic errors in angiodistonicheskom hypertensive syndrome type that is diagnosed as hypertensive disease I or I-II stage.
Highlights determining the correct etiological diagnosis is a comprehensive examination of the patient, data of dynamic monitoring of them and knowledge of the conditions of his labor.
patient's condition severity of disability depends on the core symptoms of occupational disease, taking into account the severity of angiodistonicheskih phenomena.
