摘要:

Endurance-trained individuals generally have lower cholesterol and triglyceride and higher high-density lipoprotein concentrations than do their sedentary counterparts. It is not clear how much of the reported differences in lipid values are attributable to an acute residual influence of the most recent exercise session. Five endurance-trained men had their total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), and triglyceride (TG) determined before, during an ultramarathon road race (after 20, 30, and 50 miles) and 30 minutes and 18 hours after the race. Only LDL was significantly changed during the race (lower after 30 and 50 miles), however, a significant decline in TC (14%), LDL (16%), and TG (26%) concentrations were observed 18 hours after the ultramarathon road race. These findings concur with others demonstrating that exercise can have an acute influence (the day after exercise) on changing blood lipid concentrations. Factors influential to inducing acute postexercise changes and potential implications are discussed.

摘要:

This is a descriptive study of a program of early discharge, early rehabilitation and early return to work after acute myocardial infarction. In 1985, all patients below 67 years of age from Trondheim, Norway and neighboring communities who were discharged from the Regional Hospital, after acute myocardial infarction (AMI) were referred for treatment at the outpatient clinic at Physical Medical Department 1–2 weeks after discharge from the hospital. From the total number of 135 patients, 36 (27%) were discharged after 5 days or less, and 74 (55%) during the first week after AMI. One hundred and five patients (78%) had a submaximal, symptom-limited exercise test on an average of 19 days after their infarct with an average working capacity of 104 watts at a submaximal endpoint rating of perceived exertion (RPE) 15 on the Borg scale. Eighty-two percent of the patients returned to work after their infarction, 18% of them within 4 weeks and 59% within 8 weeks after their acute event.

摘要:

To facilitate evaluation of the education component of pulmonary rehabilitation programs, the authors developed and validated a knowledge test covering the content areas identified as common to programs nationwide. Procedures were divided into five stages: item construction, item testing, test validation, program evaluation, and cross testing of the final form. Results from 27 programs demonstrated an improvement from pretest and posttest scores (F(1,57) = 58.44,P= 0.000) and from posttest and the 3-month follow-up (F(2,57) = 9.99,P= 0.003). The final form of the test has high internal consistency (Cronbach's alpha = 0.86). Development of further educational evaluative instruments specific to pulmonary rehabilitation programs is recommended.

摘要:

To evaluate the effect1of a monitored rehabilitation program on restenosis after successful emergency percutaneous transiuminal coronary angioplasty (PTCA), the authors compared the results of a rehabilitation group (N = 60) with a matched group (N = 68) of patients who received the usual post-PTCA care provided by their physician or cardiologist. The rehabilitation group trained for 12 weeks, 2 to 3 times/week for 45 to 60 minutes each on a variety of stationary equipment at a heart rate of 70 to 85% of the age-predicted maximum. They also underwent an 8-session educational program and 6 months follow-up of risk factors for secondary prevention of coronary artery disease (CAD). Because the majority of patients who restenose do so during the first 6 months after PTCA, the study was terminated 5 ± 1 months after the procedure. Between groups comparison after 5.5 ± 1 months showed: 1) significantly (T< 0.001) lower cholesterol and low density lipoprotein levels for the rehabilitation group; 2) significantly (P< 0.001) higher physical work capacity (Mets), high density lipoprotein (P< 0.001), and ejection fraction (T< 0.05) for the rehabilitation group; 3) no group differences in body weight, number of smokers, and patients with clinically treated hypertension; and 4) no group difference in rate of restenosis; 30 and 32% for the rehabilitation and physician care, respectively. Thus, our finding does not show a relationship between significantly higher ejection fraction, work capacity and improvement in lipid profile and rate of restenosis after emergency PTCA.

摘要:

The effect of right-ventricular infarction (RVI) on functional improvement and rate of medical complications with exercise for patients in an outpatient cardiac rehabilitation program were examined. Five men, aged 36 to 65 (mean: 54.4), who had experienced hemodynamically significant RVI and completed our program (mean: 33 sessions) were compared with a control group of 40 patients, 34 men, 6 women, aged 36 to 71 (mean: 55.5) randomly selected from all patients who had completed our program during the same time period. Functional improvement over the training period was similar for RVI subjects and controls, 2.4 METS and 2.6 METS, respectively. There were significant differences between groups in rate of complications. RVI subjects experienced more ventricular dysrhythmias (P < .05), which resulted in a reduction or termination of exercise. RVI subjects were more likely to be hospitalized (P < .05) or referred to a physician from the outpatient program. These outcomes resulted in the increased use of nitrates and antiarrhythmics (P < .05) among the study group. This study suggests that outpatient rehabilitation is safe and effective for patients after RVI, when compared to a heterogenerous sample of all program participants. However, this subgroup may require close surveillance and frequent communication with the referring physician.
