AIM: To determine guideline-related pharmaceutical care issues for the prevention of coronary heart disease in hospitalised patients admitted for myocardial infarction (MI). METHODS: Consecutive patients admitted with a diagnosis of Q-wave MI to two large teaching hospitals were studied. Relevant patient medical and drug histories, co-morbidities and total cholesterol concentrations were recorded. Primary or secondary prevention treatment prior to admission was assessed using a data collection tool of 16 criteria developed from the Scottish Intercollegiate Guidelines Network (SIGN) guidelines. MAIN OUTCOME MEASURES: Frequency of adherence to defined clinical guideline criteria. RESULTS: There were 167 patients reviewed (mean age 65 years, 111 males), representing possible candidates for primary prevention (n = 98) or secondary prevention (n = 69) based on absence or presence of past history of coronary heart disease (CHD), respectively. Possible primary prevention candidates: eight guideline-based criteria were developed from the SIGN guideline. There were 85 (87%) patients with a total cholesterol concentration available on admission of whom 56 (66%) had a predicted CHD risk > or = 15% and 10 (12%) had CHD risk > or = 30%. Of those with CHD risk > or = 15% 6 (11%) had been receiving an anti-platelet agent and of those with CHD risk > or = 30% only 1 (10%) was recorded as taking a statin. Of known hypertensives with CHD risk > or = 15%, 21% (5/24) were not recorded as having received treatment. Secondary prevention candidates: a further eight guideline-based criteria were developed from the SIGN guidelines. There were 42/65 (65%) candidates for aspirin documented as receiving it. There were 22/47 (47%) of those who had a total cholesterol > or = 5 mmol/l and/or known history of hypercholesterolaemia receiving a statin (representing 76% of the known hypercholesterolaemic patients identified in the community). Of statin-treated patients with a cholesterol measured on admission, 44% (7/16) had cholesterol remaining > or = 5 mmol/l. Beta-blocker use was 27/62 (44%) and ACE inhibitors use was 11/31 (36%) of those eligible. Sublingual GTN was recorded in 36/69 (52%). CONCLUSION: The study has identified opportunities for improved pharmaceutical care in primary and secondary CHD prevention among those destined to suffer an MI. Candidates for secondary prevention are potentially identifiable from community pharmacy patient medication records from which the contribution of pharmacists in primary care might be targeted. The findings were obtained during a period of evolution of the evidence-base and so they establish a baseline for future work. 相似文献

Atherosclerotic cardiovascular disease is extremely common in older adults and the potential benefits of secondary prevention are perhaps greater in this population than in younger patients. While there is good evidence that secondary prevention efforts are justified in patients up to 80 years of age, limited data are available on secondary prevention in octogenarians and there is no evidence to guide treatment in patients ≥ 90 years of age. Further, the value of secondary prevention may be confounded by prevalent comorbidities, polypharmacy, and limited life expectancy. It is therefore essential that all management decisions be made in relation to individual preferences and goals of care, with understanding by patients that benefits as well as risks may increase with age. Furthermore, research is needed to refine markers to better delineate which older adults are most likely to benefit from preventive therapies. 相似文献

The aldo-keto reductase (AKR) superfamily comprises enzymes that catalyze redox transformations involved in biosynthesis, intermediary metabolism, and detoxification. Substrates of AKRs include glucose, steroids, glycosylation end-products, lipid peroxidation products, and environmental pollutants. These proteins adopt a (β /α )8 barrel structural motif interrupted by a number of extraneous loops and helixes that vary between proteins and bring structural identity to individual families. The human AKR family differs from the rodent families. Due to their broad substrate specificity, AKRs play an important role in the phase II detoxification of a large number of pharmaceuticals, drugs, and xenobiotics. 相似文献

The effects of disability on an aging population's health and welfare are an important issue in gerontological research. The rapid growth of the elderly population and increases in longevity have led to an ongoing debate about whether longer lives can be matched by longer active lives that are free from disability. After a detailed review of current disability literature, the authors discuss the impact of disability in the elderly, defining disability and reviewing three classes of disability—physical, mental, and social. Both subjective and objective disability measures are described, and disability trends and prevalence rates are reviewed and compared cross culturally, by gender, by age, and over time. The path from chronic disease to disability is described and the consequences of living with disability are discussed in terms of family burdens and the increased need for medical care. 相似文献

Abstract Aim: The aim of this study was to investigate whether there are any differences in awareness of ability between persons with left and right hemispheric stroke. Methods: The sample consisted of data from the Assessment of Awareness of Ability (A³) database, primarily consisting of clients admitted to occupational therapy services. In total the study included 183 data records from clients, 78 with left and 105 with right hemispheric stroke. Awareness of ability was assessed using the Assessment of Awareness of Ability (A³). Differences in awareness were investigated using t-tests, CI, effect size, and differential item functioning. Results: No significant overall mean difference (t-test = 1.31, p = 0.19) in awareness between left and right hemispheric stroke was identified. However, significant differences (p < 0.05) were identified on three specific items included in the A³. In these cases, persons with right hemispheric stroke showed a more limited awareness. Conclusion: Persons with right hemispheric stroke have more pronounced problems with being aware of limitations in specific ADL performance skills compared with persons with left hemispheric stroke. 相似文献

This investigation addresses functions/impairments, abilities/disabilities and quality of life (QoL) in a consequtive series of non-hospitalized long-term survivors [2, 5–12 years] of subarachnoid haemorrhage (SAH). The investigated parameters of functions/impairments were: motor, language, perceptual and memory functions. Abilities/disabilities studied were: activities of daily living (ADL) including both personal- and instrumental ADL, working and leisure capacities. Quality of life was assessed using a double visual analogue scale. Occurrence of depression was registered using a self-rating scale.A questionnaire focusing motor and language impairments, personal ADL, work and leisure activities was initially mailed to 324 subjects. Most of them answered the questionnaire. Ten hospitalized subjects could not validly report their functions and abilities and for that reason were excluded.In a follow-up investigation up to 247 long-term non-hospitalized subjects were investigated by a physician and an occupational therapist. A total of 82% had at least one impairment. The majority (73%) had memory impairment and among these subjects equal proportions (about 50%) had impairments of long-and short-term memory. Forty-five percent were perceptually impaired, while motor impairment occurred for 25% and aphasia in 10%. Only a small minority (9%) were, according to self-reports, regarded as being to some extent disabled in personal ADL. The corresponding numbers of disabled in instrumental ADL, leisure and working-capacity were 52%, 48% and 40% respectively. Depression was found in 22%—among whom the majority had minimal or mild depression. Overall QoL was judged to be unchanged or increased in 62% of cases and, therefore, decreased in 38%.As expected, impairments to a significant degree caused disabilities. None of the five different categories of impairment were associated with mood (depressed/not depressed) and QoL (decreased/not decreased). Occurrence of depression was significantly associated with the different aspects of disabilities. In contrast, among a series of instrumental ADL-variables, leisure and working capacity, QoL was influenced negatively only by decreased ability to act sociably and, to a minor extent, by depressed mood.Judging from the extent of decreased quality of life, it appears that nearly 40% of all non-hospitalized former victims of SAH have not coped successfully with the impact of the SAH. A follow-up programme aiming at optimizing the coping process of SAH victims is, therefore, outlined 相似文献
