Abstract
Aim. This study aimed to examine the effect of open visiting hours on sleep quality, anxiety, and satisfaction of patients undergoing coronary artery bypass graft surgery (CABG).
Background. The importance of visiting patients after CABG has been emphasized in various studies, but there is insufficient evidence to confirm whether restricted /open visits may have more positive or negative effects than each other.
Method. In this clinical trial study, 60 post-CABG patients, admitted to Shahid Rajaei Cardiovascular, Medical and Research center, were randomly selected and divided into experimental (n=30) and control group (n=30). Patients in experimental group received an open visiting schedule (free visiting) and those in control group experienced a regular visiting schedule (restricted visiting). Anxiety was measured on the second and fourth days of hospitalization by the Spielberger Anxiety Inventory (STAI), sleep quality was measured by Richard Campbell and satisfaction was assessed through researcher-made questionnaire on the fourth day of hospitalization. Data were analyzed using independent t-test in SPSS-20 software.
Findings. There was a statistically significant difference between control and experimental groups in terms of anxiety mean score (43.97±6.76 against 35.90±4.31, respectively) (p≤0.0001). There was also a statistically significant difference between control and experimental groups in terms of mean score of patient satisfaction (46.13±7.15 vs 32.23±4.67, respectively) (p≤0.0001). A statistically significant difference was found between control and experimental groups in terms of sleep quality mean score (2.33±0.8 vs 3.33±0.75, respectively) (p≤0.0001).
Conclusion. Open visiting can reduces anxiety, and improves sleep quality and patients' satisfaction after CABG.

Abstract
Aim. This study aimed to address whether spiritual intelligence was correlated with self-efficacy in patients with acute coronary syndrome (ACS).
Background. Patients experiencing acute coronary syndrome (ACS) are often required to enhance their empowerment skills to manage their signs and symptoms in an effective manner. In this sense, self-efficacy has been considered as a useful factor to develop self-care practices and minimize the risks of coronary artery disease (CAD).
Method. Using a descriptive-correlational research design, a total number of 136 patients admitted to cardiac care units (CCUs) of the hospitals affiliated to Shahid Beheshti University of Medical Sciences, Tehran, Iran, were selected through the convenience sampling. The data were further collected via the demographic characteristics information questionnaire, King’s Spiritual Intelligence Self-Report Inventory (SISRI, 2008), and the Cardiac Self-Efficacy Questionnaire (CSEQ) developed by Sullivan et al. (1998), and then analyzed using the SPSS version 22.
Findings. Most patients in this study (61.8 percent) were male, married (69.1 percent) with a mean age of 58.85. Moreover, the score of spiritual intelligence was 47.18. The patients received a mean score of 13.72 in the “critical existential thinking” subscale and a mean score of 10.19 in the “personal meaning production” subscale. The mean scores for the “transcendental awareness” and “conscious state expansion” subscales were also 9.70 and 9.47, respectively (p=0.01).
Conclusion. It was concluded that higher levels of spiritual intelligence could improve self-efficacy in patients affected with ACS; therefore, adopting strategies to boost this type of intelligence could augment resilience in such individuals.
