Abstract
Aim. This review examines
cardiovascular diseases as the most common disease of the elderly population,
and discusses about causes and methods of prevention, mitigation and treatment.
Background. Nowadays, with
increased level of health and life expectancy, the phenomenon of elderly and
increase in chronic diseases is a main issue. In modern societies, aging and diseases of this
period of life create a high cost for health care system.
Methods. This review was
conducted by searching out databases such as Google Scholar, Elsevier, PubMed,
PMC, and Springer for the time period of 2008 to 2016.
Findings. In addition to the
impact of aging on the body organs, especially the cardiovascular system,many factors including biological factors,
lifestyle, risk factors for heart disease, underlying disease, psychosocial
factors and personality factors, may influence the acuity of cardiovascular
diseases. During aging, many irreversible changes occurs in all body systems
including cardiovascular system. These changes cause hardness, thickening and
narrowing of the arteries. With the narrowing of the heart arteries and
increased blood pressure, the heart needs to work harder to pump the blood,
resulting in left ventricular hypertrophy. Impaired cell growth and
proliferation of fibrous tissue occurs as a result of the problem in production
of impulse and electrical conductivity of the heart. Increase in volume of the
left ventricle and blood vessel narrowing lead to ischemia of the heart. Early
heart disease with progression to irreversible heart failure results in
disability, exercise intolerance, and taking multiple medications in elderly,
and ultimately, death may occur. By understanding the mechanisms of aging and
cardiovascular disorders and modifying influential factors, the process of
development of cardiovascular disease can be slowed down and the complications
can be prevented.
Conclusion. Aging may lead to
irreversible cardiovascular disease with the ultimate result of chronic heart
failure. Compliance with lifestyle modification may prevent early occurrence of
this phenomenon and some of its complications such as disability and death.
