The aim of the article was to point out recorded cardiovascular deaths did not copy the real number of cardiovascular deaths, but may also include other causes of deaths. We evaluated all death notifi cations reported to the Statistical Offi ce of the Slovak republic during the 10-year period, that is 519,680 cases in total. We analysed the year of death, location of death and the cause of death. The causes of deaths were split into three groups: cancer deaths, cardiovascular deaths (CVD) and other deaths. We used the fuzzy c cluster analysis and the basic epidemiological and statistical methods for the evaluation. We uncovered some Slovak districts had long-term higher mortality (Lučenec, Rimavská Sobota, Rožňava, Trebišov and Krupina), as well as the other districts having the long-term lower mortality (Bratislava, Košice, almost all Žilina region, Poprad, Spišská Nová Ves and Dunajská Streda). The cancer and cardiovascular deaths signifi cantly correlated in terms of the Slovak districts. Evaluating the mutual causes of death proportion we identifi ed two groups of Slovak districts; the fi rst group of districts showing higher CVD deaths had lower cancer and other deaths, the second having higher proportion of cancer and other deaths reached the lower CVD deaths. It seems deaths have the similar pattern throughout the whole country, and the numerical differences are probably given only by the quality and the quantity of the death certifi cation.
