Abstract
Aim. The aim of this study was to examine the effect of self-management training and follow-up with phone calls or mobile social network on the blood pressure of people with hypertension.
Background. Hypertension is one of the main causes of preventable death worldwide, and self-management training and follow-up is of particular importance in these patients.
Method. This randomized controlled clinical trial was conducted on 100 patients with primary hypertension referred to AL-Zahra hospital, Isfahan, Iran in 2016. The patients were recruited through convenience sampling and were allocated by blocking randomization into four groups, control group, “self-management education without follow-up” group, “self-management education by social network follow-up” group (education and weekly follow-up for 6 weeks) and “self-management education by telephone follow-up” group (education along with weekly calls for 6 weeks). Data were collected before and 6 weeks after intervention. The data were analyzed using Chi-square test, ANOVA, and paired t-test in SPSS, version 16.
Findings. After intervention, the study groups were significantly different in terms of blood pressure (P ≤0.0001). According to Scheffe post hoc test, intervention groups (with and without follow-up) had a statistically significant difference regarding to the blood pressure when compared with compared with the control group (P≤0.0001). Scheffe post hoc test results showed that three interventions (education without follow-up, education with telephone follow-up and education with social networks follow-up) did not differ in terms of effect on systolic and diastolic blood pressure.
Conclusion. Self-management training and follow-up by telephone or mobile social network were effective on the blood pressure of people with hypertension. Nurses can take a positive step towards improving the management of hypertension with a comprehensive patient education and follow-up.

Abstract
Aim. This study was conducted to examine the effect of self-management program on major advers cardiac complications of coronary angioplasty in patients referred to Tohid Hospital in Sanandaj, Iran, in 2018.
Background. Coronary artery disease is the leading cause of death in people over 35 years of age in Iran. Coronary angioplasty is one of the most successful treatment techniques in people with coronary artery disease with some unwanted cardiac complications. Reducing these complications is one of the important goals of health care systems.
Method. This was a quasi-experimental study that was conducted on 101 people with coronary artery disease undergoing angioplasty. The samples were selected by convenience sampling method based on inclusion criteria, and then randomly assigned to the experimental (n=51) and control (n=50) group. Data collection tools included a demographic information questionnaire and a checklist of coronary angioplasty complications. The intervention was implemented in sessions of 45 to 60 minutes duration three times per week in the presence of a family member and a copy was handed in. This intervention was continued for six months in the experimental group. During intervention period, the patient’s condition and the implementation of the self-management program were followed up by phone. The control group received only routine care and the experimental group received both routine care and self-management program. Cardiac complications were assessed in the first, third and sixth months following intervention. Data were analyzed in SPSS version 21 using Chi-square, t-test and generalized estimation equations.
Findings. The groups were homogenous in terms of age, gender, marital status, level of education, place of residence, employment status, body mass index, number of children, history of hyperlipidemia, history of diabetes, history of hypertension, history of alcohol consumption, history of heart attack, and type of artery involved. Generalized estimation equations showed that after intervention, the rate of complications of target vessel revascularization (P=0.04), second coronary angioplasty, (P=0.005) and coronary artery bypass graft surgery (P=0.003) were significantly different between the control and experimental groups. However, there were no statistically significant difference between groups in terms of recurrent angina complications (P=0.066), myocardial infarction (P=0.069) and death (P=0.019).
Conclusion. The implementation of self-management program can reduce complications after coronary artery angioplasty. It is recommended for nurses to apply self-management programs and follow-up after discharge  for this group of patients.
