Agreement analysis was conducted using Cohen’s Kappa statistics and the Chi Square statistic is used for testing relationships between variables. Results: Agreement analysis of CVDs subgroups showed that the value of the Kappa coefficient range were from κ = 0.34 for Chronic rheumatic heart diseases to κ = 0.93 for Acute rheumatic fever diseases. The values of the Kappa coefficient for the 10 most CVDs ICD-10 codes were in the range from κ = 0. 44 for I25.9 to κ = 0. 77 for I80.2.
