Cardiovascular diseases in elderly are major cause of expiry

Cardiovascular disease in elderly


Cardiovascular diseases as hypertension and cerebrovascular diseases and heart diseases as coronary artery disease, arrhythmias and heart failure, increased incidence with increasing age.The aging process itself also affects the cardiovascular system. It is difficult to differentiate “;normal “; aging is inevitable, once the age-related disease, which is potentially preventable or treatable. Age-related changes are more likely to be in the  “ old old “  who have escaped cardio-vascular disease early in life. This group reflects the dual process, often interacting biological aging of the cardiovascular system and age-related pathology.




Otherwise healthy people, the decline is probably not very important, but when the second condition, such as coronary artery or valvular disease, affects the heart, these age-related changes may exacerbate the problem or its treatment. management system also has experience gradual changes over the decades.



The walls of the arteries tend to lose elasticity and harden, even in the absence of internal blockade by fatty deposits (atherosclerosis). In general, this class can lead to high blood pressure called isolated systolic blood pressure greater (see below). Heart disease, including coronary heart disease, hypertension, cardiac arrhythmias and valve, increasingly common with age. At the age of 80 years, for example, 20 percent of Americans have symptomatic coronary artery disease. The change of role in several risk factors for the subject of this chapter because there is no reason to make changes in lifestyle, supposedly to prevent or slow the progression of coronary disease in the elderly. uncomfortable old heart can affect the quality of life, longevity, or both.



While heart disease is the largest cause of expiry among older Americans, and other problems, such as arrhythmias  and valve dysfunction are important because they show some  symptoms such as pain in the chest and fatigue, difficulty breathing ( dyspnea ) and fainting.



Practitioners whether decades of exposure to factors of cardiovascular risk may be compromised in the future. They also wonder if there is sufficient time for appropriate prevention measures for their effectiveness and applicability. But it is important to recognize that the life expectancy, even after the age of 80 years, about eight years.



Interpretation of information epidemics in the elderly is difficult because we must consider the prevalence of heart in this age, comorbidity, higher mortality and natural selection. concurrent disease is common in life can alter the association between risk factors and incidence of coronary heart disease.



Because hidden, serious disease of coronary artery disease, half of elderly patients from rich countries the distinction between primary and secondary prevention is blurred. In this age of sediments causes the development of proven or clinical events may be particularly important. All prospective studies of coronary heart disease, it is not possible to take account of competing causes of death.



The decrease in the strength of coronary risk factors with age may be due to the phasing out of the vulnerable population. Moreover, risk factors measured in the elderly may not reflect lifetime exposure to those observed to mitigate its impact on coronary heart disease.


The prevailing view that the power to reduce coronary risk factors in elderly because of reluctance to intervene.



However, to reduce the hazard ratio is offset by a significantly increased risk, so that makes the risk management more cost-effective compared to older age in between. Elderly patients at high risk of one or more risk factors for coronary heart disease can be effectively targeted to address the overall risk assessment for unnecessary overtreatment can be avoided.
