Hemoglobin as a predictor of cardiovascular problems

: Analyzed were data of longitudinal studies of health and peripheral blood of AF pilots and navigators at the age of 20, 25, 30, 35, 40 and 45. The survey of 846 men 30 years and older was conducted in two 5-yr cycles. In this cohort, 329 had diagnosed neurocirculatory dystonia (NCD), vegetovascular dystonia, and class I essential hypertension. Sixty nine men were afflicted with myocardium dystrophy or cardiosclerosis. The dispersion analysis provided evidence that 15 to 5 years prior to establishment of the NCD diagnosis hemoglobin first increases and then decreases. The dispersion analysis applied to the data of repeated measurement attested to the predictive meaning of the hemoglobin rise and decrease. Results support the hypothesis according to which hemoglobin is but a stable individual risk factor but reflects pre-clinic developments in organism.
