摘要:

Determinants of time and frequency of return to work after a first myocardial infarction (MI) and attitude towards work and attributation of MI were studied in 192 patients one year after their M1. At follow-up, 81° had resumed part- or full-time. work. Severity of the infarction, pessimism, frequency of angina pectoris at two to three months, and being single correctly predicted return to work for 83° of the patients who resumed work. The median time of return to work was 16 weeks. Delayed return to work was caused by heavy physical work prior to the MI, severity of the MI, self-reported and medically assessed chest pain, readmissions, and lack of support two months after the MI. Low work motivation was correlated with failure to resume work. Myocardial infarction patients rated the work situation as physically heavier and less satisfying compared with control subjects. Work-related factors were the most frequent explanation for the cause of the MI.

摘要:

Thirty wives of coronary artery bypass graft surgery patients were interviewed privately in their homes during the second or third week after their husbands' were discharged from a metropolitan hospital. The main life-style changes reported by the wives were increased fatigue and anxiety, better interpersonal relationships with spouse, changes in daily life-styles at home and outside the home, and differences of opinion with spouse about convalescent expectations. Most wives obtained convalescent information prior to their husbands' hospitalization. Although the physician was ranked as the most important information source, the most frequent source of information was someone with experiential knowledge. The majority of wives had excellent knowledge of coronary risk factors. However, the majority expressed concerns about their husbands' diet, weight, and the preparation of nutritious meals low in sodium and cholesterol. The majority of wives had insufficient or only fair knowledge of their husbands' medications. Some wives were concerned that their spouses needed to continue to take cardiac medication prescribed before surgery. The majority of wives had insufficient knowledge of the surgery and its relationship to coronary artery disease and to angina. The most frequently expressed concerns were future heart problems, death, prognosis, surgical success, behavioral fluctuations (including depression), and the potential for recurrence of arterial blockages. The wives had good or excellent knowledge of physical discomforts. However, they expressed concerns about their spouses' pain, posture, sleeping difficulties, and leg edema. Although the wives had excellent knowledge of the recommended activities, they lacked information about sexual activity. The greatest and most frequently expressed concerns related to the amount, type, and time of resumption for specific activities.

摘要:

A retrospective pilot analysis of the case records of 20 patients who showed improvement in work capacity during a 13-week cardiopulmonary rehabilitation exercise program was performed. It was initially hypothesized and then determined that the ratio of work load to heart rate followed an exponential law. The clinical usefulness of this ratio and the exponential law governing its change during a patient's reconditioning is considered. There emerges the possibility that this simple data processing technique may help to provide individualized quantified patient monitoring. Sources of error are discussed and methods by which more precise data may be obtained are indicated.

摘要:

Carbon dioxide rebreathing is widely used as a noninvasive technique for the determination of cardiac output (Q), stroke volume (SV), and arteriovenous oxygen difference (A-VC>2). This paper provides a review of the studies concerned with the development of the two most commonly used methods, the equilibirum method, and the exponential method. The reliability and validity of both methods have been found, in most investigations, to be very good during exercise. Some authors report acceptable levels of reliability and validity at rest as well. A comparison of the two methods indicates differences in the applicability of each. Various procedures that have been employed in the implementation of the technique by different investigators are reviewed with regard to their potential to produce valid and reliable measures of Q and associated parameters. Particular attention is given to the equilibrium method and to the various investigations that have established procedures for its use. This review provides the background for the development of CO2 rebreathing methods and recommendations concerning implementation of the technique.
