[Relationships between body composition and hematological parameters in long-living patients with coronary artery disease.].

The study objective to investigate hematological parameters and determine the relationships between these indicators and body composition in centenarians with coronary artery disease. This work is a cross-sectional study, which enrolled 239 patients over 90 years old hospitalized with a diagnosis of coronary artery disease; most of them (67,8%) were women. The age of the patients ranged from 90 to 106 years, averaging 92,8 (±2,5) years. Body composition was analyzed by dual energy X-ray absorptiometry. Anemia was detected in 108 (45,2%) patients, while a significant direct correlation was found between the hemoglobin level and all indicators of bone mineral density (p=0,004-0,00002). Patients with osteoporosis had lower levels of hemoglobin (p=0,002) and blood iron (p=0,02). Direct correlations were established between the hemoglobin level and lean tissue mass (p=0,06-0,003). Patients with obesity had higher levels of hemoglobin (p=0,007), erythrocytes (p=0,03), leukocytes (p=0,04), lymphocytes (p=0,01) and monocytes (p=0,05). A direct correlation was registered between the platelets count and fat tissue mass (p=0,04-0,00006) along with an inverse correlation between platelets and lean tissue (p=0,001-0,0004). The study results indicate significant relationships between the parameters of body composition and hematological indicators.
