Association between white blood cell count and risk factors of coronary artery disease

Area of Science:

• Cardiology
• Epidemiology
• Hematology

Background:

• Epidemiologic studies indicate a correlation between white blood cell (WBC) count and myocardial infarction risk.
• Investigating the association between WBC count and coronary heart disease (CHD) risk factors in a specific population is crucial for public health.
• Understanding these links can aid in early detection and prevention strategies for cardiovascular diseases.

Purpose of the Study:

• To assess the association between white blood cell (WBC) count and other coronary heart disease risk factors.
• To investigate the role of WBC count in identifying individuals at high risk for cardiovascular events.
• To examine these associations within a southern Italian population.

Main Methods:

• Utilized baseline data from 1091 subjects (522 males, 569 females) from the 'Montecorvino Rovella Project'.
• Employed multiple linear regression analysis to determine associations between WBC count and various risk factors.
• Compared WBC counts across smoking status groups (smokers, ex-smokers, never-smokers).

Main Results:

• WBC count was significantly higher in smokers compared to ex-smokers and never-smokers.
• Multiple linear regression revealed a positive association between WBC count and triglycerides, cholesterol, fasting glucose, and diastolic blood pressure.
• These findings highlight a potential atherogenic profile linked to elevated WBC count.

Conclusions:

• Elevated WBC count is associated with key coronary artery disease risk factors, particularly smoking, in this southern Italian cohort.
• The study identifies an atherogenic profile associated with high WBC counts.
• WBC count may serve as a valuable marker for coronary risk assessment in apparently healthy individuals, warranting further investigation into its independent role.
