Influence of age on prevalence rates of chronic complications of hospitalized aged patients with hypertension——analysis of 17,682 cases / 老年心脏病学杂志（英文版）

ABSTRACT

Objective To understand the relationship between age and chronic complications in hospitalized aged patients with hypertension, to provide evidence for hypertension prevention and control. Methods To retrospectively analyze the clinical and laboratory data on 17,682 patients with essential hypertension during Jan 1st,1993-Dee 12th, 2008 in PLA general hospital. Results 1)Among all of the inrolled cases, those aged 60-64 account for 27.87%, 65-69 years group account for 26.55%, 70-74 years group accounted for 23.96%, 75-79 years group accounted for 14.14%, 80-84 years group accounted for 5.26%, 85-89 years group accounted for 1.69%, > 90 years accounted for 0.41%. 2) The prevalence rate of chronic complications in 60-69 years group were 31.3-31.2% for diabetes and,22.6-27.0% for cerebrovascular disease, 9.5-11.1% for myocardial infarction, 6.7-9.1% for heart failure, 5.8-6.0% for renal dysfanction 4.9-6.8% for atrial fibrillation, 0.1-0.3% for multiple organ dysfunction syndrome (MODS) in the elderly(P <0.05 ). 3) The first four complications of hypertension were diabetes(33.5%), cerebrovascular disease (31.9%), myocardial infarction(13.2%) and heart failure(12.3%) in 70-74 years group (P<0.05), cerebrovascular disease (42.8%), diabetes (32.8%), heart failure (16.5%) and myocardial infarction(15.9%) in 75-79 years group (P<0.05), cerebrovascular disease (45.4%), diabetes (35.0%), heart failure (21.1%) and myocardial infarction(15.9%) in 80-84 years group (P<0.05), cerebrovascular disease(42.5%), diabetes (35.8%), heart failure (23.1%) and renal dysfanction (17.7%) in 85-89 years group(P<0.05 ),and cerebrovascular disease (45. 2%), heart failure(31.5%), diabetes (26.0%) and renal dysfanction (20.5%) in patients more than 90 years group (P<0.05). Conclusions The prevalence rate and kinds of chronic complications in hospitalized aged patients with hypertension were changed with the increasing age, and the first kind of complication is cerebrovascular disease. It is of more importance to prevent the occurrence of renal dysfanction and heart failure in those hypertension patients who were more than 80 years old.
