摘要:

Cardiac Rehabilitation Programs is a regular feature in which the protocols of innovative and unique cardiac rehabilitation programs are described. The co-editors invite the staffs of other outstanding programs to submit descriptive articles concerning the financial, methodologic, and creative aspects of their program for possible publication in the journal.

摘要:

Exercise testing in children is performed for evaluation of maximal work capacity and adds important data for the formulation of an exercise prescription. Indications for testing are (1) assessment of oxygen supply/demand ratio in congenital heart defects, (2) evaluation of chest pain, (3) evaluation of dysrhythmias, (4) evaluation of systemic hypertension by blood pressure response to exercise, (5) evaluation of the results of medical and/or surgical therapy, and (6) the evaluation of the respiratory component of the disease. The methods of testing are described.There are very few contraindications to exercise in children with heart disease. Most of these children can exercise without restriction. Children with symptomatic heart disease should have their exercise modified based on clinical evaluations and exercise testing. Except for acute inflammatory disease or profound congestive heart failure, children with heart disease should be given a progressive exercise program to predetermined level. They should he retested after six months in the program to modify the levels of exercise. The details of physical rehabilitation programs for children with heart disease are discussed.

摘要:

Fifty-seven patients who had a significant (50) narrowing of a nongrafted coronary artery and a baseline cholesterol level >250 mg/dl were studied. All patients underwent repeat coronary arteriography after two years. Thirty-six colestipol responders (cholesterol levels reduced at least 15 within one month of therapy) were compared to 21 nonre-sponders who were given placeo for 23 months after a one-month exposure to colestipol. Baseline risk factors and demographic characteristics were similar for the two groups. In comparison to baseline arteriography, six of the 36 drug-treated patients showed progression of atherosclerosis, whereas ten of 21 placebo-treated patients demonstrated progression (P <.02). Drug-treated patients demonstrated an average 21 decrease in cholesterol levels, whereas placebo patients did not experience a significant reduction in cholesterol levels. Our study suggests that a significant reduction (15) in serum cholesterol level is associated with a reduced likelihood of progression of coronary atherosclerotic lesions assessed by scheduled repetitive coronary arteriography in hyperlipidemic subjects who demonstrate significant coronary artery narrowing.

摘要:

The effect of beta blockade with a single, 100-mg oral dose of metoprolol or matched placebo was studied in 12 healthy, young men during both cycle and treadmill exercise. During maximal exercise on the cycle ergometer with work rate increased as a ramp function at 50 W/min and during the Bruce treadmill test, maximal oxygen uptake (VO2max) and maximum heart rate (HRmax) were significantly reduced by beta blockade (P <.0005). The maximum responses on the cycle were significantly lower than on the treadmill (P <.0001). These results are discussed relative to previous studies that have been conducted on either the cycle or treadmill but not on both. It was noted that the lower statistical power of a treadmill-only test would have yielded a nonsignificant result for the effect of beta blockade on VO2maxSubmaximal estimates of cardiac output indicated similar responses to beta blockade in both exercise modes. Cardiac output was significantly lower with beta blockade because of a marked reduction in HR in combination with a sinall increase in stroke volume. It is concluded that both cycle and treadmill maximal exercise performance are impaired by 100 mg oral metoprolol. The greater statistical power of the present investigation may partially explain the discrepancy between this observation and previous studies.
