摘要:

The relationship between physical activity and health is investigated in an effort to determine whether increased physical activity or participation in sports results in a more healthy life. Although several of the questions that were investigated were impossible to answer if strict scientific criteria are invoked, the available information allows us, in many instances, to make reasonably safe recommendations. For example, the great majority of the population, both healthy individuals and those with chronic illnesses and functional handicaps, can improve their physical condition and thus their quality of life with increased physical activity. Although training beyond certain limits will probably reslt in a modest degree of health gain beyond that already attained, there is also a point at which further training results in injuries and stress. Nevertheless, it can be confidently asserted that both on theoretic and experimental grounds regular physical training for the general population can be recommended with reasonably great certainty and that any adverse effects associated with such activities are very small in comparison with the health benefits.

摘要:

The heart rate (HR) responses and symptomatology during predischarge low-level graded exercise testing (CXT) and postdischarge 24-hour ambulatory electrocardiographs (ECG) monitoring were compared in 62 patients with documented myocardial infarction (MI). The mean peak HR attained during GXT (113 ± 17 beats/min) was modestly but significantly higher (P< .05) than that attained with ambulatory ECG monitoring (106 ± 17 beats/ min). However, 34% of the patients reached a higher peak HR with out-of-hospital activities than with GXT. Also, 56% of the patients showed sustained HR elevations in excess of recommended levels during the first week at home. Importantly, complex arrhythmias, angina pectoris, or other symptoms were not specifically related to these excessive HR elevations. The results of the present study indicate that activities performed by post-MI patients soon after hospital discharge lead to (1) HR increases that, for some patients, exceed the peak HR attained during predischarge GXT, and (2) sustained HR elevations within the first week following discharge that frequently exceed commonly prescribed HR levels for home activities. These results suggest that common HR and MET guidelines established for inpatient exercise programs and predischarge exercise testing may be overly conservative for some post-MI patients.

摘要:

The prevalence, causation, and treatment of sexual dysfunction in post-myocardial infarction (MI) patients are reviewed. Sexual problems are common in such patients, often predate the heart attack, and can be precipitated or exacerbated by both organic and psychologic factors. Intercourse requires the expenditure of only a moderate amount of energy, of which many cardiac patients are capable. However, the associated sympathetic nervous activity may increase the risk of a fatal arrhythmia. Consequently, all patients with symptomatic arrhythmias or palpitations require exercise testing or Holter monitoring and prophylactic medication if necessary. Much traditional advice given to the post-MI patient about sexual activity has yet to be validated, but the alleviation of cardiac symptoms during sex and the prescription of an exercise program may improve sexual functioning in some of these patients.

摘要:

QUESTIONS AND ANSWERS is a regular feature in which leading clinicians and researchers share with their colleagues their views on matters that are relevant to cardiac rehabilitation. The editors invite Journal of Cardiac Rehabilitation readers to suggest questions for discussion in this forum.

摘要:

The present study was undertaken to identify patients' past and future sources of cardiovascular information, perceived barriers to obtaining information, learning preferences, and reading and comprehension abilities. The findings indicate that the patients planned to use doctors, nurses, and television as future sources of cardiovascular information and that embarrassment was the greatest barrier to patients obtaining information. In addition, patients preferred learning style was one-to-one interactions with doctors and nurses. The patients' mean reading and comprehension abilities were at the eighth grade level, which indicated that they probably could not read and understand the current cardiovascular literature available to them.

摘要:

Patients dislike using the bedpan and urinal while in bed and often insist that it would be easier and better for them to get out of bed to toilet. Little data are available about the physiologic costs of toileting. Therefore, we measured oxygen uptake (VO2), peak heart rate (HRpeak), peak rate-pressure product (RPPpeak), rating of perceived exertion, and preference in 42 women who used the bedpan and bedside commode for urination and in 53 men who used the urinal while in bed and standing. The subjects included 26 healthy volunteers, 16 cardiac outpatients, 27 medical inpatients, and 26 acute post-myocardial infarction patients (two to 28 days postinfarction). No physiologically important differences were found between in-bed and out-of-bed toileting. Both in-bed and out-of-bed toileting produced small increases in energy cost and myocardial work over resting levels, with a mean VO2< 1.6 times resting VO2, a mean HRpeak< 100 beats/min, and a mean RPPpeak< 11,200. The subjects clearly preferred getting out of bed to toilet. Out-of-bed toileting produces minimal energy expenditure and cardiac stress and can help reduce bed rest-induced orthostatic intolerance. In-bed toileting should be reserved for patients with specific contraindications to postural change.
