The potential of cardioscreening in oil and gas refinery

Abstract

Aim: to compare the results of examination conducted among oil and gas refinery employees, obtained during yearly periodic medical examination with the results obtained during cardioscreening. Material and Methods – 47 employees (64% - men, mean age 52 ± 8 yrs) of large oil and gas refinery were examined by cardiologist in 2018. Six months before the cardioscreening all employees underwent yearly periodic medical examination. The data of anamnesis, laboratory and instrumental findings (blood glucose, lipids, ECG) of examinees were analyzed. Revealed risk factors, the levels of risk SCORE, diagnosis and recommendations made during periodic medical examination and during cardioscreening were compared. Results – In the studied group dyslipidemia was observed in 39 employees (83%). Elevated blood glucose was revealed in 30 examinees (64%). Left ventricle hypertrophy on ECG was determined in 6 patients (13%). Hypertension was diagnosed in 35 subjects (75%) by cardiologist vs 26 subjects (55%) by therapeutist, diabetes mellitus was diagnosed in 8 (15%) vs 4 (8,5%) subjects by cardiologist and therapeutist correspondingly, smoking – in 20 (43%) and 16 (34%) of employees correspondingly (p < 0,001). Mean systolic BP was 152±20 mm Hg during cardioscreening versus 133±24 mm Hg during periodic medical examination (p < 0,001). High and very high risk SCORE have had 26 subjects (55%) according the data of cardiologist and 15 subjects (32%) according the data of therapeutist (p < 0,001). Conclusion – In the companies with abusive working conditions it is necessary to distinguish high and very high cardiovascular risk groups by means of cardioscreening.

“…At the same time, the methods of the noncontact determination of SpO 2 -oxygen saturation of blood using a video camera have been developing since 2005 [13,14]. Currently, the diagnostic capabilities of the methods of the contact and non-contact PPGIs are expanding and include not only the assessment of the heart rate, determination of the vascular wall properties, the level of blood oxygen saturation [15][16][17][18][19], but also the determination of the pulse wave propagation time, as well as its spatial distribution over the skin surface [20,21].…”
