Key result
The prevalence of arterial hypertension and obesity increases with age, while the relationship between mortality and certain risk factors weakens due to a survival effect in the elderly population.
The management of coronary heart disease in the elderly requires a complex approach due to the simultaneous presence of multiple interacting risk factors and the 'survival effect'.
Highlights need for age-adjusted risk models in elderly; leaves open survival bias effects in observational data.
The treatment and prevention events against cardiovascular diseases have changed the age population structure. As by forecast, in RF the part of population older than economically active age will increase to 29,1% by the year 2030, hence increasing prevalence of ischemic heart disease (CHD). Therefore, one of the main currents is assessment of risk factors impact on morbidity and mortality from CHD among elderly. One of specifics of elderly population is simultaneous presence of several factors that enhance each other. Nevertheless, the prevalence of arterial hypertension and obesity increase with the age, and part of smokers and those with hypercholesterolemia increases, and relation of mortality with some risk factors does weaken with the age. That is a “survival effect” — earlier mortality of persons with adverse prognosis. Therefore, the specifics of CHD course in elderly dictates for necessity of an approach development to complex and methodic healthcare management.

Имаева et al. (2016) conducted a review in Coronary heart disease. Risk factors was evaluated. The prevalence of arterial hypertension and obesity increases with age, while the relationship between mortality and certain risk factors weakens due to a survival effect in the elderly population.
