Analysis of the decrease in deaths due to coronary disease between 1995 and 2010. IMPACT CHD Argentina Study.

Objetive: To quantify the contribution of risk factors and treatments in the reduction of mortality due to coronary heart disease in Argentina between 1995 and 2010.

Results: We used the validated IMPACTCHD model integrating data on effectiveness, use of treatments and changes in the risk factors between 1995 and 2010 in people older than 25 years in Argentina. The difference between the coronary deaths observed and expected in 2010 was distributed between treatments and risk factors.

Conclusions: One out of every two MPP due to coronary heart disease in Argentina between 1995 and 2010 was due to treatments and one third to the improvement of risk factors. The decrease in blood pressure, cholesterol and smoking was limited by increases in the prevalence of obesity, sedentary lifestyle and diabetes. This study was possible thanks to the collaborative work to the cardiovascular epidemiology.
