The relationship between exercise tolerance and quality of life in angina pectoris

Abstract

Summary:The relationship between exercise tolerance assessed by a conventional exercise stress test using a standard Bruce protocol and quality of life (QoL) was studied in 50 patients with stable angina pectoris (AP). Before the exercise test, patients completed three self-administered QoL questionnaires, the Psychological General WellBeing Index, an Angina-Specific QoL Questionnaire, and Jenkins' Sleep Dysfunction Scale. Total exercise time (r= -0.40) and time until onset ofpain (r= -0.44) were significantly correlated with perceived physical limitations. Somatic symptoms were related to total time (r= -0.38). Apart from a significant correlation between depressed mood and total exercise time (r=0.36), there was no corresponding correlation with well-being and sleep disturbance. These results suggest that exercise stress tests do not rcilect quality of life in patients with AP.

Symptom overlap in patients with upper gastrointestinal complaints in the Canadian confirmatory acid suppression test (CAST) study: further psychometric validation of the reflux disease questionnaire

“…Correlations were mostly moderate to strong, the exception being the assessment of HB severity in the HB group, where the correlation between physician rating and patient reporting was low. The discrepancies between patientreports and observer-reports are well documented 30,[39][40][41] , and this highlights the need for consolidation of physician examination with patient reporting. 42 For clinical trials, the most important criteria of an instrument is probably its ability to detect small changes over time.…”

Physical Activity, Aging, and Psychological Well-Being

“…These procedures ranged from submaximal cycle ergometry (Massie & Shephard, 1971;Moses et al, 1989) to maximal graded exercise stress tests with assessment of expired gases (Blumenthal et al, 1991;Wiklund et al, 1991). Although studies employing maximal graded tests often report that ~0 , m a x was achieved, in reality it is often difficult if not impossib!e to achieve a verifiable steady-state ~0 , m a x with older adults.…”

“…Twenty one of these studies reported exercise training programs as being associated with positive changes in aerobic capacity/physical fitness, ranging from a 5% increase in V02max (King et al, 1993) to a 16% increase in V0,max (Pierce et al, 1993). Two studies (Segebartt et al, 1988;Wiklund et al, 1991) reported physical fitness assessments associated with a single graded exercise test, and therefore no improvements were noted. Nevertheless, these studies are included in Table 2.…”

Self-Efficacy and Health Status in Patients With Coronary Heart Disease: Findings From the Heart and Soul Study

“…Little is known about the determinants of health status in patients with cardiovascular disease (5)(6)(7)(8)(9)(10)(11). In particular, the extent to which health status is determined by psychological versus physiological measures of cardiac function is unclear (12)(13)(14).…”
