Clinical results and quality of life after percutaneous transluminal coronary angioplasty: a preliminary report

Measuring health outcomes in stroke survivors

Stroke frequently results in psychologic distress and activity limitations across multiple domains of functioning. However, most stroke outcome measurement tools and clinical trial endpoints are narrowly focused on neurologic symptom status and physical aspects of functioning, and rarely assess other important components of health. In this article, I discuss the limitations in the measurement of nonfatal stroke outcomes; propose a minimum set of fundamental assessment domains comprising a comprehensive assessment of health status in stroke survivors; and describe the conceptual development of the Burden of Stroke Scale, a comprehensive, patient-reported measure of functioning and well-being for stroke survivors.

Impact of smoking on health-related quality of life after percutaneous coronary revascularization

BACKGROUND

PTCA is performed primarily to improve health-related quality of life (HRQOL) in patients with symptomatic coronary artery disease. In patients undergoing PTCA, smoking has been shown to increase risks of late myocardial infarction and death. Whether smoking also affects HRQOL after PTCA is currently unknown.

METHODS AND RESULTS

We examined the relation between smoking status and HRQOL among 1432 patients who underwent PTCA as part of 2 multicenter clinical trials. HRQOL was assessed with the use of the Medical Outcomes Study SF-36 questionnaire. Patients were classified as smokers (n=301), quitters (n=141), or nonsmokers (n=990) on the basis of their smoking status at the time of their index procedure and during the first year of follow-up. For the overall population, HRQOL improved significantly after PTCA for all scales except general health perception, with improvements ranging from 5.5 points for mental health to 23.2 points for role-physical functioning. After adjustment for baseline characteristics and initial HRQOL, nonsmokers had gains at 6 months that were larger than those of smokers for all health domains: physical function (15.4 versus 10.4 points), role-physical (24.5 versus 13.9), pain (18.4 versus 13.3), general health perception (1.7 versus -4.5), vitality (11.0 versus 4. 7), social function (12.8 versus 3.5), role-emotional (13.5 versus 6. 7), and mental health (6.8 versus 0.8; P:<0.02 for all comparisons). Quitters had 6-month HRQOL improvements that were greater than those in smokers for all domains as well. Findings were similar at 1 year.

CONCLUSIONS

Quality-of-life benefits of PTCA are diminished by continued smoking. Efforts to promote smoking cessation at the time of PTCA may substantially improve the health outcomes of these procedures.

Quality of life comparisons after coronary angioplasty and coronary artery bypass graft surgery

OBJECTIVE

To examine the differences in realization of expected benefits, complications, and quality of life (QOL) 3 months after percutaneous transluminal coronary angioplasty (PTCA) and coronary artery bypass graft (CABG) surgery.

DESIGN

Nonexperimental, prospective, and comparative. Before discharge, participants listed benefits expected from the procedure, as well as comorbid health problems (Charlson Comorbidity Index) and complications. At 3 months, they quantified their realization of expected benefits, reported postdischarge complications, and completed Ferrans and Powers' Quality of Life Index-Cardiac Version III.

SAMPLE

36 patients who had PTCA; 38 patients who had CABG.

RESULTS

There were no differences between groups in realization of expected benefits or QOL. Patients who had CABG reported a greater number of complications after discharge, and a greater proportion of patients who had PTCA reported angina. Patients who had PTCA and then recurrent angina had significantly lower health QOL and psychologic and spiritual QOL.

CONCLUSIONS

Patients who undergo CABG need guidance regarding what complications to expect, and patients who undergo PTCA need to know that recurrent angina is possible and how to manage it.

Percutaneous transluminal coronary angioplasty: clinical and quality of life outcomes one year later

BACKGROUND

The quality of life status of patients prior to and following percutaneous transluminal coronary angioplasty (PTCA) has not been comprehensively investigated.

AIM

This study was carried out to determine the effect that PTCA has on patients' quality of life.

METHODS

Data on 209 patients were collected one day pre-PTCA and at a mean of two and 11 months post-PTCA. Data on symptomatic status, functional capacity, life satisfaction and psychological well-being were analysed quantitatively. Clinical outcomes, patient perception of PTCA and employment status wee analysed by descriptive statistics.

RESULTS

Highly significant improvement in all quality of life measures was found at the early follow-up (p < .001). This improvement was sustained at the late follow-up. At the late follow-up, 58% of patients felt that PTCA had been very beneficial to their health and well-being, and 79% of workers had returned to work. PTCA was primarily successful in 91% of vessels dilated. There were no procedural-related deaths, 12 patients (6%) developed acute occlusion and three patients (1.5%) experienced myocardial infarction (MI). A symptomatic restenosis rate of 16% was found, including 19 patients (9%) requiring repeat PTCA and 14 (7%) undergoing coronary artery bypass grafting (CABG).

CONCLUSION

These findings suggest that, after PTCA, the majority of patients experienced improved quality of life which was sustained one year later.
