There has been considerable debate on the extent to which the decline in coronary heart disease (CHD) mortality has been caused by better control of coronary risk factors in the general population or is the result of invasive coronary interventions in symptomatic individuals. Using the Myocardial Infarction Data Acquisition System (MIDAS), a statewide database of all cardiovascular hospital admissions in New Jersey, we examined time trends in incidence of death from CHD in the years 2000 to 2014 in persons with a history of hospitalization for CHD in the previous 10 years and those without such a history. Over the 10-year study period there was a marked decline in CHD related mortality in both persons with a history of CHD and persons without a history of CHD. The decline occurred across all gender, racial and age groups and was higher in those without a prior history of CHD. This adds more evidence that the decline in CHD was not only due to advanced invasive medical and surgical treatments but also equally due to improved lifestyle, pharmacologic treatment of risk factors for CHD, and public health interventions.
