ABSTRACT
The authors studied prospects of work capacity preserving after coronary stenting in IHD and cardiac arrhythmias. Examination covered 158 railway workers underwent complete endovascular revascularization of myocardium for coronary stenosis; all of them had ventricular arrhythmias before coronary surgery. Findings are that in long-term period (in 16 months in average) after coronary stenting, grade I and III ventricular extrasystoles disappeared in 77.8 and 54.5% of cases respectively, but only in 11.9% of grade IV ventricular extrasystoles cases. Ventricular extrasystoles remained unchanged in 44.3% of cases. Reliable relationships were seen between unchanged grade IV ventricular extrasystoles and body weight index (OR = 5.49, 95% CI: 0.87-34.67), general cholesterol level (OR = 1.69; 95% CI: 1.06-2.69), low density lipoproteins (OR = 1.66; 95% CI: 1.00-2.76) and left ventricular ejection function lower 45% (OR = 1.61; 95% CI: 1.14-2.27), exertion ventricular extrasystoles before myocardium revascularization (OR = 3.1; 95% CI: 1.78-5.41). That necessitates correction of the mentioned risk factors of cardiac arrhythmias for restored work capacity.

The authors studied allostatic load in railway workers, as an indicator of stress effect. Analysis covered biomarkers that form allostatic load index, and their ratio for variable allostatic load index levels. Moderate allostatic load appeared to prevail in the examinees group. Findings are that systolic and diastolic blood pressure, general cholesterol and hemoglobin make major contribution into allostatic load index. Comparison covered models of allostatic load index calculation for variable biomarkers sets.
