Congestive heart failure (CHF) has become an increasingly important health care issue in the older population. The prevalence of cardiovascular diseases such as hypertension, coronary artery disease and valvular heart disease increase with advancing age. In addition, age-related structural and functional changes in the cardiovascular system, such as impaired ventricular diastolic relaxation, altered energy metabolism, decreased sympathetic nervous activities and increased systemic vascular resistance, predispose older people to the development of CHF. Renal function decreases in older people, and the adequacy of renal function is important in delaying progression of CHF. Renal condition should be carefully monitored to prevent adverse effects in the treatment of CHF in older patients.
Key words: heart failure, renal function, aging, heart, kidney.
