Why the study?
How much of the decline in coronary heart disease mortality in Finland between 1982 and 1997 can be attributed to improved treatments versus risk factor reductions?

Follow-up
15 years (1982 to 1997)
Key result
Between 1982 and 1997, coronary heart disease mortality in Finland declined by 63%, with improved treatments explaining 23% and risk factor reductions explaining 53-72% of the reduction.

How much of the decline in coronary heart disease mortality in Finland between 1982 and 1997 can be attributed to improved treatments versus risk factor reductions?
Risk factor reductions and improved treatments accounted for the vast majority of the 63% decline in coronary heart disease mortality in Finland between 1982 and 1997, emphasizing the need for comprehensive primary and secondary prevention.
Laatikainen et al. (2005) conducted an observational in Coronary heart disease (n=13,001). Improved treatments and risk factor reductions vs. Baseline mortality rates in 1982 was evaluated on Changes in coronary heart disease mortality. Between 1982 and 1997, coronary heart disease mortality in Finland declined by 63%, with improved treatments explaining 23% and risk factor reductions explaining 53-72% of the reduction.
