Changes in self-reported health and quality of life in octogenarian patients one month after transcatheter aortic valve implantation.

BACKGROUND: In addition to favourable results regarding mortality and morbidity it is important to identify the impact transcatheter aortic valve implantation (TAVI) has on patients' quality of life. AIMS: The aims were: (i) to describe clinical characteristics, self-reported health and quality of life in octogenarians before TAVI intervention; (ii) to determine changes in self-reported health and quality of life one month after TAVI; and (iii) to establish the clinical importance of the findings. METHODS: A prospective cohort study was conducted on consecutively enrolled octogenarians with severe aortic stenosis undergoing TAVI ( N = 65). Self-reported health and quality of life were recorded at baseline and one month later using two global questions from the World Health Organization Quality of Life Instrument Abbreviated (WHOQOL-BREF), the generic Short Form Health 12 and the disease-specific Minnesota Living with Heart Failure Questionnaire. RESULTS: One month after TAVI, WHOQOL-BREF showed that self-reported health improved moderately ( p < 0.001), while quality of life improved slightly, but not statistically significantly ( p = 0.06). There were changes in all Short Form Health 12 domains, except social functioning and role emotional. The estimated changes were 3.6 to 5.8 with large confidence intervals. The Physical Component Summary increased statistically significantly from baseline to 30 days (30.6-34.7; p = 0.02), but the Mental Component Summary did not (46.9-50.0; p = 0.13). CONCLUSION: Despite being an advanced treatment performed in a high risk population, TAVI in octogenarians improves short-term self-reported global health and generic physical health and quality of life. These patient-reported outcomes have importance, particularly in this age group.

Sleep in octogenarians during the postoperative phase after transcatheter or surgical aortic valve replacement.

BACKGROUND: Octogenarians with aortic stenosis are an increasing population of patients admitted for surgical aortic valve replacement (SAVR) or transcatheter aortic valve implantation (TAVI). Although adequate sleep is important after illness and surgery, it has scarcely been studied in the immediate postoperative phase. AIMS: To determine and compare the nature of self-reported sleep and insomnia, and recorded sleep-wake patterns in octogenarians during the in-hospital postoperative phase after SAVR or TAVI. METHODS: A prospective cohort design was used that included octogenarian patients undergoing SAVR or TAVI at a regional university hospital. Self-reports were used to document sleep and insomnia, and actigraphy was used to record sleep-wake patterns. Data were collected at baseline preoperatively, and then daily for the first five postoperative days. RESULTS: SAVR patients experienced the most insomnia on postoperative nights later in recovery, while TAVI patients experienced the most insomnia on postoperative nights early in recovery. The median total sleep time, as measured by actigraphy, was 6.4 h, and the median sleep efficiency was 79% for the five postoperative nights, but no differences were found between SAVR and TAVI patients on this parameter. All patients slept more during daytime than at night, with SAVR patients having significantly more total sleep hours for all five days than TAVI patients (p < 0.01). CONCLUSION: Octogenarians with aortic stenosis had disturbed self-reported sleep, increased insomnia, and disturbed sleep-wake patterns postoperatively, resulting in more daytime sleep and inactivity. In patients undergoing SAVR or TAVI, sleep evolves differently during the in-hospital postoperative phase.

The Norwegian Stroke in the Young Study (NOR-SYS): rationale and design.

BACKGROUND: Ischemic stroke in young adults is a major health problem being associated with a higher vascular morbidity and mortality compared to controls, and a stroke recurrence rate of 25% during the first decade. The assumed cause of infarction and the detected risk factors determine the early- and long-term treatment. However, for many patients the cause of stroke remains unknown. Risk factor profile and etiology differ in young and elderly ischemic stroke patients, and atherosclerosis is the determined underlying condition in 10 to 15%. However, subclinical atherosclerosis is probably more prevalent and may go unrecognized. METHODS/DESIGN: NOR-SYS is a prospective long-term research program. Standardized methods are used for anamnestic, clinical, laboratory, imaging, and ultrasound data collection in ischemic stroke patients aged ≤60 years, their partners and joint adult offspring. The ultrasound protocol includes the assessment of intracranial, carotid and femoral arteries, abdominal aorta, and the estimation of VAT. To date, the study is a single centre study with approximately 400 patients, 250 partners and 350 adult offspring expected to be recruited at our site. DISCUSSION: NOR-SYS aims to increase our knowledge about heredity and the development of arterial vascular disease in young patients with ischemic stroke and their families. Moreover, optimization of diagnostics, prophylaxis and early intervention are major targets with the intention to reduce stroke recurrence and other clinical arterial events, physical disability, cognitive impairment and death.

Nonemergent coronary angioplasty without on-site surgical backup: a randomized study evaluating outcomes in low-risk patients.

BACKGROUND: Percutaneous coronary intervention (PCI) in nonemergent patients with coronary artery disease in hospitals without on-site cardiac surgery backup is still controversial. To prospectively evaluate a set of low procedural risk criteria for PCI, patients with stable or unstable angina were randomized to treatment in either a community hospital, which had all supportive services except for on-site cardiac surgery, or a regional surgical hospital 213 km away. METHODS AND RESULTS: During a 4-year period, 609 (57%) of 1064 consecutive patients with stable or unstable angina who underwent coronary angiography at a teaching community hospital in Norway fulfilled the predefined low-risk criteria for PCI. The patients were randomized to treatment at either the community hospital (n = 305) or at the regional hospital (n = 304). The angiographic success rate (96% at both hospitals) and number of major periprocedural complications (overall 0.3%) were equal at the 2 hospitals. In particular, there were no deaths or need for urgent transfer to cardiac surgery. At 6 months of clinical follow-up, there was a significant higher major adverse cardiac event rate rate at the community hospital, compared with the regional hospital (6.9% vs 2.3%, respectively, P = .03) because of more repeat target vessel revascularizations. Improvement in angina functional class and exercise capacity was similar in both groups. The excluded high-risk PCI patients had higher 6-month major adverse cardiac event compared with all low-risk patients (8.4% vs 4.3%, respectively, P = .01). CONCLUSION: Selected nonemergent patients can, based on angiography, safely undergo PCI at hospitals without cardiac surgery backup. The angiographic selection criteria identified high-risk patients, which had worsened outcome at 6 months of follow-up.
