Dynamics of cardiovascular and all-cause mortality in Western and Eastern Europe between 1970 and 2000.

AIMS

Important changes in cardiovascular and all-cause mortality rates are occurring in Western and Eastern Europe, each with their own dynamics. Differences in trends will be analysed and possible causes are discussed.

METHODS AND RESULTS

Mortality data for cardiovascular and all-cause mortality rates from different countries were obtained from WHO and were analysed for the period 1970-2000. The annual changes in cause-specific mortality rates were calculated using linear and polynomial regression models. Mortality rates declined almost linearly for ischaemic heart disease, stroke, and total cardiovascular diseases between 1970 and 2000 in Western Europe. In both men and women, the decline for these diseases varied between 50 and 65% or approximately 2%/year in this period. In contrast, in Eastern Europe cardiovascular mortality rates reached a maximum in the period 1990-94, followed by a decline of approximately 3%/year in Poland, 2%/year in Hungary, and 5%/year in the Baltic states. The changes in cardiovascular mortality rates were reflected in all-cause mortality rates in both Western and Eastern Europe.

CONCLUSION

Over the past 30 years, mortality rates in cardiovascular diseases increased or decreased very rapidly. The causes are complex but changes in diet appear to play a major role. The more recent declines in Western Europe also reflect improvements in modern cardiovascular treatment.
