Background: It seems that the time of performing cardiac rehabilitation is important in determining the risk of cardiac complications in patients with myocardial infarction (MI). The present study aimed to investigate the effects of a home-based cardiac rehabilitation program (HCRP) conducted in either the morning or evening on cardiometabolic risk factors in phase IV (maintenance) MI patients.

Methods: In this randomized controlled clinical trial, 80 patients with MI were divided into 2 groups of intervention and control (40 individuals per group). Patients in each group were categorized into morning and evening subgroups (20 individuals per subgroup). The therapeutic regimen in the intervention group included HCRP, routine medications, and exercise and walking programs for 8 weeks. Patients in the control group received routine treatments for 8 weeks. Cardiovascular risk factors comprising of cardiac troponin I (cTnI), mean platelet volume (MPV), C-reactive protein (CRP), and cardiometabolic indicators including cholesterol (Cho), high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglyceride (TG), and the maximum rate of oxygen consumption (VO2 max) were measured for all patients before and after the intervention.

Results: Our results showed significant reductions in Cho, TG, HDL, LDL, VO2 max, CRP, and MPV (P < 0.05) in the group performing HCRP in the evening compared with the morning group.

Conclusion: Performing HCRP in the evening, compared with morning, can be significantly more effective in improving the levels of cardiometabolic risk factors in patients with MI. Therefore, it is recommended that rehabilitation programs be implemented in these patients in evening shifts.

Background: Hypertension (HTN) is the second leading risk factor for death and disability. One fourth of healthcare in Eastern Europe and Central Asia is being spent on blood pressure (BP)-related diseases. An important situation in patients with high BP is hypertensive crisis (BP > 180/120 mmHg), which is divided to hypertensive emergency and urgency. Therefore, here, we decided to compare the effect of captopril and clonidine in patients with hypertensive urgencies, and their side effects.

Methods: This was a parallel-group randomized clinical trial. Patients, who referred to emergency ward with any symptoms of hypertensive crisis, underwent a careful history taking and clinical examination. Individuals with systolic BP (SBP) ≥ 180 mmHg or diastolic BP (DBP) ≥ 110 mmHg with no evidence of end organ damage were randomly assigned into two interventions, clonidine and captopril. 25% decrease in BP was considered as ideal relief.

Results: Regarding the duration of response to treatment drugs, patients who received clonidine relieved significantly faster than those who received captopril (P = 0.016). Moreover, the frequencies of side effects such as headache, dizziness/vertigo, dry mouth, and drowsiness in the clonidine group were significantly lower than captopril group (P < 0.05).

Conclusion: Patients in clonidine group relieved sooner and experienced fewer side effects. Therefore, this study suggests clonidine as a more effective therapeutic for hypertensive urgency compared with captopril.

Background: Given the role of post-traumatic stress disorder (PTSD) in morbidity and mortality of cardiac patients, the present study was conducted to determine the relationship between the perception of heart disease and severity of PTSD symptoms.

Methods: Sampled using simple random sampling, 202 cardiovascular patients (50.5% women) were selected and included in this cross-sectional study. The patients admitted to a hospital from January to May 2017 in western Iran were selected and asked to complete the self-report demographic and cardiac risk factors inventory, Brief Illness Perception Questionnaire (Brief-IPQ), and National Stressful Events Survey PTSD Short Scale (NSESSS) checklist. The results were analyzed using the Pearson correlation coefficient and multiple regression analysis.

Results: The mean age of patients was 53.5 ± 11.9 years. The results of the correlation coefficient showed a significant relationship between all the components of illness perception, except personal and treatment control, with PTSD (P < 0.05). The regression model could predict 22.5% of PTSD variance and the greatest role was for the emotional representation (P = 0.002) and female sex (P = 0.008).

Conclusion: The perception of cardiovascular patients of the cognitive and emotional components of the disease, especially in women, plays a significant role in experiencing the symptoms of PTSD. Thus, health professionals have to monitor all these components, especially the patient's perceptions and emotional reactions, and to come up with proper and timely interventions for patients at risk to control the adverse effects of PTSD after cardiovascular events.

Background: Cyanoacrylate (CA) has been used as an embolizing agent in the treatment of greater saphenous vein (GSV) insufficiency in recent years and the results regarding the use of this method have started to be published. To the best of our knowledge, the publications in literature do not mention about a significant negative effect of endovenous CA (EVCA) embolization. We aimed to evaluate the effects and undesirable events of this relatively new treatment method and compare them with literature, using the follow-up data of our patients.

Methods: Patients who had GSV insufficiency for at least 3 months and were treated with EVCA embolization because of this disease were included in the study. Patients were excluded if they had deep vein thrombosis (DVT), excessive tortuous GSV, and peripheral neuropathy. Hospital archive records were reviewed and undesirable events like DVT, thrombophlebitis, and pain related to this treatment procedure were recorded.

Results: EVCA embolization procedure was performed in a total of 54 patients with an average age of 49.36 ± 13.06 years for the purpose of treating GSV insufficiency. One patient was observed to develop n-butyl CA (NBCA) extension of approximately 5 mm from saphenofemoral junction (SFJ) to the main femoral vein and painful thrombophlebitic reaction was observed in 6 extremities at the first control examination.

Conclusion: In our opinion, while EVCA embolization is a treatment option with similar success rates to endovenous thermal ablation (EVTA), it should be kept in mind that there may be a possibility of developing thrombophlebitis and NBCA extension or thrombus extension to the deep veins.

Background: Atrial septal defects (ASDs) are one of the most common congenital cardiac abnormalities. Repair of these defects is a quite secure and routine operation. The most common complications were postoperative atrial arrhythmias, sinus arrhythmia, and atrioventricular (AV) blocks requiring pacemaker implantation, mediastinal bleeding, and transient ischemic attacks (TIAs) or strokes. Iatrogenic diversion of the inferior vena cava (IVC) to the left atrium (LA) during surgical closure of an ASD is a very rare complication.

Case report: We reported a patient who had a history of cardiac surgery in another center at the age of seven and was introduced to our clinic with complaints of dyspnea and cyanosis of extremities on exertion. She underwent surgery in our center with diagnosis of iatrogenic diversion of IVC to LA.

Conclusion: The most common mechanism suggested is a large eustachian valve being mistaken for the inferior rim of the ASD.

Background: Heart failure is one of the most common syndromes in the world and Iran. Caring for heart failure patients can cause a burden on their caregivers. Traditional and modern treatment techniques are often used for patients with heart failure. This study was conducted with the aim to " determine the impact of telenursing on short-term caregiver burden of patients with heart failure discharged from hospitals in Iran".

Methods: This randomized clinical trial (RCT) was undertaken in Kerman, Iran, in 2018-2019. From among caregivers of patients with minimal grade 2 heart failure, 100 patients were randomly selected to participate in the study. The intervention group, in addition to routine discharge training, received training and care files with videos and related photos via social media every other day for 1 month. The control group received only routine discharge training. The Caregiver Burden Scale (CBS) was completed before and after the intervention in both groups. This scale includes 22 items scored on a Likert scale ranging from 0 (never) to 4 (almost always). The data were analyzed using SPSS software.

Results: The mean age of the participants was 56.44 ± 13.09 years. The mean caregiver burden score in the control and intervention groups at baseline was 37.26 and 35.58, respectively, and after the intervention, it was 34.56 and 24.28, respectively. A significant difference was found in the 2 groups after the study; the mean caregiver burden score in the intervention group was significantly reduced compared to the control group after the study.

Conclusion: Telenursing reduces the caregiver burden in caregivers of patients with heart failure. Telenursing can be considered as an auxiliary method to control the symptoms associated with heart failure.

Background: Pulmonary complications following cardiopulmonary bypass (CPB) pump during coronary artery bypass grafting (CABG) are relatively common and the incidence of cognitive dysfunction is reported as ranging in rate from 30% to 80% in the early postoperative period. The purpose of this study was to assess the effect of modafinil administration on the prevention of pulmonary and cerebral complications and shortening the hospital stay after CABG surgery.

Methods: This randomized double-blind intervention-controlled clinical trial was performed on 74 patients (37 in the intervention group and 37 in the control group) undertaking CABG surgery. The intervention group was orally treated with doses of 200 mg of modafinil on the day of surgery, and on the morning of the day after surgery, the second dose of modafinil 200 mg was given to patients. The control group underwent a placebo with the same intervals.

Results: Administration of modafinil in intervention group significantly decreased the time to reach consciousness (P = 0.001), ventilator time in intensive care unit (ICU) (P < 0.001), length of stay in ICU (P = 0.009), duration of hospitalization (P = 0.008), and arterial blood carbon dioxide pressure (PaCO2) (P = 0.047). In the intervention group, no patients with delirium, agitation, respiratory depression, non-invasive respiratory ventilation, and endotracheal re-intubation were observed.

Conclusion: Modafinil tablet as a respiratory and brain stimulant through the central nervous system (CNS) can improve the quality of breathing and arterial blood gases (ABGs) and also can increase the level of consciousness and shorten the recovery time.
