Abstract
The prevalence of coronary heart disease (CHD) and associated manifestations with ischaemic resting electrocardiogram (ECG) changes, clinical findings and sociodemographic factors were studied in 1990–1991 among an elderly population in southwestern Finland. One of the specific
aims was to describe the health-related quality of life of elderly coronary heart disease patients, i.e. the associations between CHD and physical, psychological, cognitive and social functioning. 488 men and 708 women aged 64 years and over (93% of those eligible) participated in this cross-sectional epidemiological survey in the rural district of Lieto. The participants were examined and interviewed during two visits to the local health centre. An ECG and a chest x-ray were taken and a clinical examination was made by a doctor. The Rose questionnaire was used to determine the prevalence of angina pectoris (AP). The Minnesota codes were used in the analyses of ECG findings. The medical records were reviewed.
The prevalence of AP was 9.1% (95% Confidence Interval 6.7–12.0) among men and 4.9% (3.5–6.8) among women. The respective figures for past myocardial infarction (MI) (based on the medical records or a major or moderate Q/QS item on ECG, codes 1.1–1.2) were 13.9% (10.9–17.0) and 6.5% (4.8–8.6). Ischaemic ECG findings (codes 1.1–1.3, 4.1–4.4, 5.1–5.3, 7.1) were common: 32.9% (28.7–37.1) of men and 39.3% (35.7–43.0) of women had such changes. The total prevalence of CHD, including AP, MI, past coronary bypass surgery or angioplasty or ischaemic ECG findings, was 37.7% (33.4–42.0) in men and 42.0% (38.3–45.6) in women.
The patients and controls were mainly aged, non-institutionalized, community-living persons. The patients with CHD (AP and/or a past MI) had more difficulties in physical functioning than their age- and sex-matched controls. According to logistic regression analyses, CHD was not independently associated with difficulties in physical functioning. However, physical disability was associated with the use of cardiovascular drugs and also with old age, the use of psychotropic drugs, depression and cancer. More male patients than controls had depression measured on the Zung Self-Rating Depression Scale. The depression had often gone undiagnosed, especially among men. Among men, the most important factors associated with depression were difficulties in physical functioning and widowhood or divorce, while among women, previous depression and the use of ACE inhibitors emerged as significant. There were no differences between the patients and controls in cognitive functioning. The male patients had a higher frequency in visiting activity than the controls. Old age, difficulties in physical functioning, CHD and chronic obstructive pulmonary disease were associated with impaired social functioning.
In conclusion, CHD is common in the Finnish elderly. The clinical picture of CHD in elderly people is varying. It seems that CHD has no independent impact on functional disability in the elderly. Old age, sociodemographic factors, medication and other chronic diseases are also contributors.
