Mortality rates and number of deaths from cardiovascular diseases in Italy from 1982 to 1993.: A comparison with total and tumour data

In this study the recent Italian trends in cardiovascular deaths and mortality are described and compared with the trends regarding total and tumour deaths and mortality. The data, collected from the National Institute of Statistics, are presented as total (T), tumour (TU), cardiovascular (CV), cerebrovascular (CVD), ischemic heart disease (IHD) standardized mortality (sm), non-standardized mortality (nsm) and absolute number of deaths (d), according to sex, age, and geographical area. Data on sm were available only for the age group <75 years old. In males, from 1982 to 1993, T-sm fell by 18%, TU-sm by 4%, CV-sm by 30%, CVD-sm by 38% and IHD-sm by 24%. In females, the decrements were generally greater: T-sm 20%, TU-sm 4%, CV-sm 35%, CVD-sm 39% and IHD-sm 28%. Since 1985/87, tumours have been the leading cause of mortality, in both sexes. By 1991/93, the highest rates of CV, CVD, IHD-sm were reported mostly in the South of Italy. Non-standardized mortality rates for tumours increased, and for cardiovascular diseases decreased, in both sexes and age groups (<75 and ≥75 years old). As for sm, in the group <75 years, old tumours have been the leading cause of mortality since 1985/87, but in the older age group CV-nsm has been more than twice TU-nsm. By 1991/93 in comparison with 1982/84, CV deaths have fallen by 6% (−28% in the age group <75 years, +3% in the age group ≥75 years), while TU deaths have grown by 17% (+3% in the age group <75 years, +45% in the age group ≥75 years). Considering all age groups, by 1991/93 the absolute number of CV-d (239.241) was much greater than the number of TU-d (151.908); overall, almost 70% of CV-d and 40% of TU-d took place in the older age group. For the near future, the rapid aging of the Italian population (from 1982/84 to 1991/93 there was a 40% increment in the population older than 75 years) is a relevant variable to take into account. Thus, despite the ‘reassuring’ fall in CV-sm and nsm, cardiovascular diseases are expected to remain the major cause of death and physical disability in adults.
