Smelters working with aluminum and brass-bronze alloys and electric welders working with carbide and low-alloyed steel develop primary myocardial injury independent on hypertension and coronary atherosclerosis. This injury is characterized by structural disorders such as myocardial concentric and eccentric hypertrophy, concentric remodeling left heart myocardium, non-coronarogenic pain, changes of T-wave in ECG, and cardiac arrhythmias. According to the 10th International classification of diseases, such signs should be considered as cardiomyopathy caused by environmental exposure, namely by fine-particle aerosols of condensates of zinc, aluminum and iron oxides having slow solubility and cytotoxity.
