Insights
Cardiovascular disease (CVD) mortality decreased from 1975-1985, but its proportion of overall deaths rose. Ischemic heart disease deaths declined, while cerebrovascular disease deaths increased, differing from US patterns.
Area of Science:
- Epidemiology
- Public Health
- Cardiovascular Medicine
Background:
- Cardiovascular disease (CVD) remains a leading cause of mortality globally.
- Understanding temporal trends and patterns in CVD mortality is crucial for public health interventions.
- International comparisons can highlight unique population health challenges and opportunities.
Purpose of the Study:
- To analyze trends in cardiovascular mortality between 1975 and 1985.
- To compare cardiovascular and cerebrovascular disease mortality patterns with those in the United States.
- To explore potential risk factors contributing to observed mortality differences.
Main Methods:
- Analysis of mortality data from 1975 to 1985.
- Calculation of age-adjusted mortality rates per 100,000 population.
- Comparison of mortality rates for ischemic heart disease and cerebrovascular disease between the study population and the USA.
Main Results:
- Overall cardiovascular mortality decreased from 170.6 to 164.5 per 100,000.
- The relative proportion of cardiovascular deaths increased from 23.0% to 27.6% of all causes.
- Ischemic heart disease mortality declined, while cerebrovascular disease mortality increased compared to US data.
Conclusions:
- Despite an overall decrease in cardiovascular disease mortality, its proportional impact on overall deaths grew.
- Distinct patterns in ischemic and cerebrovascular disease mortality compared to the US suggest the influence of specific risk factors.
- Further research into lifestyle factors like diet, hyperlipidemia, hypertension, and smoking is warranted to explain these epidemiological differences.
Abstract:
From 1975 to 1985 mortality from cardiovascular causes has decreased from 170.6 to 164.5 per 100,000 while its relative participation among all causes has increased from 23.0 to 27.6%. Total cardiovascular and ischemic deaths in the 35 to 74 year age range has also decreased. A lower mortality from ischemic heart disease but a higher one from cerebro vascular disease in all age groups compared to those reported in USA is shown by these data. Differences in the prevalence of risk factors such as diet, hyperlipidemia, hypertension and smoking may underlie this different mortality pattern from cardiovascular disease.
