Gender differences in treatment-seeking delay in acute myocardial infarction.

Delay in seeking treatment for the symptoms of myocardial infarction can contribute to significant mortality and morbidity. Although pre-hospital delay is a serious problem in both women and men, women appear to delay substantially longer than men. Possible reasons for longer delay in women include the age at which women experience first myocardial infarction, the presence of certain chronic diseases, possible atypical presentation of cardiac symptoms in women, and physician and layperson misperception of the significance of chest pain in women. Recommendations for studying the problem of pre-hospital delay in women and for designing future interventions to reduce delay are discussed.

Effects of a multidimensional cardiopulmonary rehabilitation program on psychosocial function.

The effects of participation in a structured, outpatient cardiac rehabilitation program on psychosocial function after acute myocardial infarction or coronary artery bypass surgery, or both, were evaluated prospectively in 141 patients who were married or living with "a significant other" (89% men, mean [+/- standard deviation] age 63 +/- 9 years old). Forty-one patients who were participants in a 3-month cardiac rehabilitation program were compared with 100 patients who did not participate in a formal program. On average, patients in both groups were well educated, older Caucasians who had minimal cardiac dysfunction (New York Heart Association class I or II). Patients in the 2 groups were not different at baseline in sociodemographic or clinical characteristics or in any of the dependent measures of anxiety, depression, psychosocial adjustment to illness or marital adjustment. Six months after initial testing, patients who attended cardiac rehabilitation were significantly less anxious (F[1,139] = 5.09, p = 0.03), less depressed (F[1,139] = 8.39, p = 0.004), had better psychosocial adjustment (F[1,139] = 5.87, p = 0.02), and were more satisfied with their marriages (F[1,139] = 8.6, p = 0.004) than nonparticipants. The findings support the effectiveness of group cardiac rehabilitation for this subgroup of patients in facilitating their psychosocial recovery after an acute cardiac event.

MCL1 and MCL6 compared to V1 and V6 in distinguishing aberrant supraventricular from ventricular ectopic beats.

Use of V1 and V6 has been suggested for distinguishing aberrant supraventricular from ventricular ectopy. For two decades, "modified" leads MCL1 and MCL6 have been widely used as V1 and V6 substitutes for bedside monitoring, but their use has never been validated. To determine the value of MCL1 and MCL6, 81 morphologically distinct wide QRS ectopic beats were recorded from 46 patients during cardiac electrophysiological study. As determined by the His-bundle electrogram, 31 of the ectopics were aberrant supraventricular, 50 were ventricular. A new criterion, measurement of QRS onset to the predominant peak or nadir of the complex, was valuable in diagnosing wide complexes in MCL6 and V6. An interval of 50 msec or less predicted aberrant supraventricular ectopy; an interval of 70 msec or more predicted ventricular ectopy. There was agreement between the modified and conventional precordial leads regarding which QRS patterns were useful in distinguishing aberrant supraventricular from ventricular ectopy. A greater proportion of wide complexes in MCL1 and V1 exhibited patterns useful in making the diagnosis compared to MCL6 and V6. Using well-established criteria, the proportion of correct diagnoses that was made from individual leads was: MCL1 = 86%, V1 = 85%, MCL6 = 72%, V6 = 67%. The bedside leads (MCL1 and MCL6) were not statistically different in diagnostic accuracy from their conventional lead counterparts (V1 and V6); however, MCL1 and V1 were superior to MCL6 and V6. When the new criterion was added to make the diagnosis from MCL6 and V6, no difference in diagnostic accuracy was present between the four leads.

Different perspectives: the effect of heart disease on patients and spouses.

Nurses working in critical care units play an important role in helping patients and their families cope with illness. In this article, heart disease is used as a paradigm for discussion of the coping processes of patients and families as they adapt to an acute event. Patients and spouses demonstrate different but equally important responses that may increase marital conflict and impede recovery. The denial frequently used by patients is in direct contrast to the oversolicitousness demonstrated by spouses. Early assessment of potential family dysfunction is essential in order to plan and implement interventions that promote family coping. In this article, the interventions available to nurses working with families in an acute care setting are reviewed. Interview data from one study of cardiac patients and their spouses is used to illustrate the family dynamics seen in the acute and chronic phase of recovery and to provide examples of the couples' differing perspectives on the helpfulness of various interventions.

Treatment-seeking behavior among those with signs and symptoms of acute myocardial infarction.

Significant delays in seeking definitive treatment for the signs and symptoms of acute myocardial infarction increase morbidity and mortality. In most studies, delay times average more than 4 hours. The following variables are associated with increased delay: a medical history of angina, diabetes mellitus, or hypertension; older age; black race; seeking advice from a family member or a physician; symptom onset on a weekday; and attempts at self-treatment. Variables associated with reduced delay times are the following: pain recognized as cardiac in origin, hemodynamic instability, severe chest pain, younger age, and consultation with a coworker. Surprisingly, patients who have already experienced a myocardial infarction are just as likely to delay as patients who have not had this experience. These findings provide direction for developing and testing patient and family interventions, establishing community education programs, and reducing patient delay in response to the signs and symptoms of acute myocardial infarction.

Cardiopulmonary resuscitation skills retention in family members of cardiac patients.

The purpose of this study was to determine if the use of a retention strategy would maintain cardiopulmonary resuscitation (CPR) skills in family members of cardiac patients. Thirty-one subjects trained in CPR received retention packets 3 and 6 months after CPR training. Sixteen subjects were tested for CPR retention at 7 months after initial training, and 15 at 12 months. Likelihood chi 2 was used to compare the 7- and 12-month groups. There were no differences between the 7- and 12-month groups, because CPR retention overall was poor. Only 19.4% of subjects reported using the retention packet; therefore, subjects were regrouped into practice and no practice groups for purposes of further statistical analysis. There were significant differences in retention in subjects who practiced compared with subjects who did not. These findings underscore the importance of promoting practice/review after initial CPR training for family members of cardiac patients.

Serum prolactin concentrations in patients with the acquired immunodeficiency syndrome.

Experimental evidence suggests that prolactin is an important immunomodulator hormone. Because this endocrine-immune link may represent a potential new therapeutic avenue, we considered its application in states of immunodeficiency. We hypothesized that serum prolactin concentrations might be abnormal in AIDS. To test this hypothesis, we measured serum prolactin concentrations in blood samples obtained from patients who had either AIDS (n = 15) or AIDS-related complex (n = 12), asymptomatic subjects who were antibody-positive for human immunodeficiency virus (HIV) (n = 10), HIV antibody-negative homosexual subjects (n = 10), and heterosexual HIV antibody-negative controls (n = 21). We found no difference in the serum prolactin concentrations between the five subject groups. We conclude that circulating prolactin values are not altered by HIV infection; however, the possibility that prolactin administration may modulate immune function remains to be tested.

Psychosocial adjustment of patients with ventricular dysrhythmias.

This study was conducted to document whether differences in psychosocial adjustment exist between cardiac arrest survivors and patients with recurrent ventricular dysrhythmias and to identify specific patient characteristics associated with psychosocial adjustment in those individuals who have experienced ventricular dysrhythmias with or without cardiac arrest. Nineteen cardiac arrest survivors and 21 ventricular dysrhythmia patients participated in the study. There was no significant difference in psychosocial adjustment between the two groups. The characteristics that were found to be predictive of psychosocial adjustment in patients with ventricular dysrhythmias were marital status, number of dysrhythmic events, and history of heart failure.
