Many factors affect the hypertensive patients’ quality of life. Identifying the factors related to the quality of life can help to promote the quality of life in hypertensive patients. This study aimed to determine the predictive role of illness acceptance and social, individual factors in the hypertensive patients’ quality of life.

Methods & Materials: 

This correlational, cross-section study was conducted in 2020-2021 on 245 hypertensive patients referred to a hypertension clinic in Lahijan selected by the convenience sampling method. Data were collected by a questionnaire, including demographic information, Acceptance of Illness Scale and the WHO's Quality of Life-Brief questionnaire. Data were analyzed by multiple linear regression at a 95% confidence level using the SPSS software version 23.

The mean score for the quality of life was 65.32±12.18 (0-100) and for the acceptance of illness was 31.83±4.98 (8-40). Age, sex, employment status, marital status, monthly income, family arrangement and the acceptance of illness were identified as the predictors of quality of life in hypertensive patients (P<0.001). According to the coefficient of determination (R2=0.401), the variables of the final regression model explained about 40% of the quality-of-life changes among hypertensive patients.

Given that the acceptance of illness and some social, individual factors can affect the hypertensive patients’ quality of life, focus on the strategies to promote the acceptance of illness and paying attention to social, individual factors can help improve the quality of life among hypertensive patients.

Today, hypertension is one of the most common cardiovascular disorders being prevalent in developing countries. This study was conducted to determine the role of interpersonal dependence and social support with the mediation of hope affecting the resilience of patients with high blood pressure.

The statistical population of the study included all patients with hypertension referring to medical centers in Tehran with the final sample group of 250 cases. Participation in this study was voluntary and the sampling process was performed by purposeful sampling method. The data collection tools were as follows: Connor-Davidson Resilience Scale, Perceived Social Support designed by Vaux, Adult State Hope Scale developed by Snyder, and Interpersonal Dependency Inventory designed by Hirschfield. Data analysis was carried out using the path analysis method.

Based on the results of the study, social support, interpersonal dependency, and hope had a positive correlation with the resilience of hypertensive patients. It was also revealed that resilience was effected indirectly by social support. The variables of interpersonal dependence and social support and the variables of resilience have significant direct effects. In addition, both interpersonal dependence and social support variables have an indirect effect on resilience, of which only the indirect effect of social support on resilience is significant. 

It was revealed that hope can play the role of mediator between social support and resilience in patients with hypertension. Furthermore, this variable is effective in increasing resilience in such patients.

Crocus sativus (C. sativus) petals attenuates smooth muscle tension and blood pressure in control animals. However the antihypertensive effect and its mechanisms haven’t been recognized. This study investigates the antihypertensive effects of C. sativus petals’ aqueous extract in hypertensive rats and also responses of the rat isolated perfused mesenteric bed.

The interventional experimental study was performed on 20 male rats (divided to 5 and 15 rats for in vivo and in vitro studies respectively). Hypertension was induced by DOCA-salt injection (20 mg/kg, twice weekly, for 5 weeks, S.C) and water was replaced by NaCl (1%). Five weeks later, animals were anaesthetized with sodium thiopental (30 mg intraperitoneal). Then systemic arterial blood pressure was measured by cannulation of carotid artery following administration of different doses of aqueous extract of C. sativus. Isolated mesenteric beds precontracted with KCl (40 mM), and the tension was measured in presence of different concentrations of the aqueous extract. Finally, various doses of C. sativus extract were applied after incubation by L-NAME or indomethacin. The mesentry was perfused with pump and the recordings were done by physiograph.

Mean arterial blood pressure in hypertensive rats was 231±6 mmHg. Administration of aqueous extracts of C. sativus reduced the blood pressure in a dose–dependent manner. In mesenteric beds preparation, addition of C. sativus reduced the contractile effects of KCl. Incubation with L-NAME but not indomethacin abolished hypotension effect of the extract.

It was proposed that the antihypertensive effects of C. sativus petals’ extract are through the reduction in total peripheral resistance following nitric oxide production.

High blood pressure increases various cardiovascular events about 2 to 3 times in a person. The purpose of this study was to recognize the effect of Pilates and thermomechanical massage on vital sign, inflammatory markers and quality of life and mental health in women with hypertension.

: In this quasi-experimental study, 45 women with hypertension referred to internal clinics of Arak city were selected and randomly divided into three groups of Pilates, thermomechanical massage and control. Pilates and massage group performed 8 weeks (3 sessions per week and 40-45 minutes each session), but the control group did not exercise regularly during this period. Serum C-reactive protein levels, heart rate and blood pressure were measured, and quality of life and mental health questionnaires were completed. Data were analyzed using paired t-test and one-way ANOVA at a significant level of 0.05.

Results showed a significant decrease in systolic and diastolic blood pressure (p = 0.02) and inflammatory factor (p = 0.02) in both groups. There was also a significant difference between the Pilates and the thermo-mechanical massage and control groups. But there were no significant effects on heart rate (p=0.34). There was a significant improvement in quality of life and mental health in the experimental group compared to the control group.

Eight weeks of Pilates had a greater effect on blood pressure and inflammatory markers, but the effect of improving quality of life and mental health with thermomechanical massage was greater than Pilates.

Self-care, behavior changes and health maintenance are the essential factors to prevent the exacerbation of cardiovascular disease. Having a valid and reliable tool is essential to evaluate self-care status of patients with hypertension. Relatively, the present study aimed to evaluate the psychometric properties of the Persian version of the Hypertension Self-Care Profile (HTN-SCP) in patients with high blood pressure. In this methodological research, using multi-stage cluster sampling, 325 patients with high blood pressure were selected to complete the Persian version of the hypertension self-care profile. The questionnaire was translated according to WHO guidelines. Face, content and construct validity (by exploratory and confirmatory factor analysis) was investigated. Reliability was measured using the McDonald's Omega and Cronbach's alpha coefficients. Four factors, including diet and activity regimen, medication regimen, food labels and disease management were extracted based on exploratory factor analyses. They were able to explain 51.39% of the variance of all self-care variables. The fitness of the four-factor model of self-care construct was approved based on standard indices (NFI=0. 92, CFI=0. 96, PNFI=0. 80, RMSEA=0. 067). Reliability of HTN-SCP was 0.865 based on the Cronbach’s alpha coefficient. The four-factor structure of HTN-SCP suitable validity and reliability. Conclusively, given to its proper psychometric properties, this questionnaire can be used in patients with hypertension in future researches in Iran.

Hypertension is one of the most common diseases that lead to other diseases. Education of self-care behaviors is part of the management of hypertension disease. This study aimed to examine the effects of nursing intervention education on self-care behaviors in patients with hypertension.
This quasi-experimental study was conducted on 50 patients with high blood pressure referred to health centers of regions 1 and 2 in Kermanshah city during 2015-2016. To collect data, demographic and self-care measurement questionnaires were used. The questionnaires were completed by the patients before and six weeks after the face to face education. Data were analyzed using descriptive and inferential statistics by the SPSS software version 20.
The mean score of self-care before the intervention was 43.6 ± 6.8 which was increased to 66.4 ± 4.6 after the intervention (P Education of nursing interventions seems to have a positive effect on self-care behaviors of the patients with hypertension. So, the program of training self-care behaviors used in this study is recommended to promote self-care behaviors in patients with high blood pressure.

Renal artery stenosis (RAS) is the most common cause of secondary systemic hypertension. The efficacy of endovascular treatment
of patients with RAS, who achieved antihypertensive optimal medical treatment (OMT), is unclear. But it may be useful in some selected clinical scenarios, including cardiac disturbance, resistant hypertension and ischemic nephropathy.
Case Report: Our first patient suffered from resistant hypertension with end organ damages (EOD), due to significant bilateral RAS. In the second and third patients, the severe unilateral RAS was presented by resistant and malignant hypertension. In all three patients, hypertension had become under controll by medical treatment after renal artery stenting.
It seems that renal artery stenting is an effective and safe adjuvant approach in addition to the medical treatment of patients with RAS, in whom their hypertension is not only unversponsive to the OMT, but also causes EOD.

Hypertension is one of the most common chronic diseases and a major risk factor for cardiovascular diseases )CVDs( and stroke. Due to the increasing prevalence of hypertension and its serious complications, this study aimed to determine the effect of educational intervention on preventive behavior of hypertension in school students’ mothers in Eslamshahr, Iran.
In the present experimental study, a total of 112 mothers of elementary school girls and boys were selected through a two-stage cluster sampling and were divided into two groups )n=56 per group(. The lecture method of education was employed in the form of question and answer at the end of the lecture. A questionnaire survey was performed to evaluate subjects at three stages consisting of a pretest, a post-test immediately after education, and a post-test two months later. All stages of this research were conducted ethically.
The results showed that there were no statistically significant differences between test and control groups in terms of the mean knowledge and attitude score, before the intervention. Concerning the mean practice score, however, a little difference was observed. After education, by contrast, scores for all above mentioned variables were significantly increased in intervention group (P-value The results revealed that the educational program on knowledge, attitudes and behavior to promote effective preventive behavior and to increase the knowledge and attitudes can promote the preventive behavior of hypertension.

Hypertension is constantly increasing in different societies. The aim of this study was to determine the impact of educational intervention based on PRECEDE – PROCEED model on the lifestyle changes among hypertension patients in rural health centers of the Jahrom county. In this experimental study, 40 patients were in the intervention group and 40 patients in the control group. Educational intervention was designed based on PRECEDE – PROCEED model and implemented on the intervention group. The instrument was a researcher-made questionnaire including questions on demographic characteristics and PRECEDE - PROCEED constructs. Data were gathered before and 2 months after the intervention. Data were analyzed using independent sample t-test, paired sample t-test and chi-square test using SPSS19 software. After the intervention, the intervention group than the control group scores of predisposing factors (knowledge and attitudes), reinforcing factors and enabling factors increased significantly among intervention group (p <0.05). The significant increase in levels of physical activity with dietary intervention group improved significantly compared to the control group (p <0.05). The training based on PRECEDE - PROCEED model increases predisposing factors (knowledge and attitudes), enabling and reinforcing factors in patients with hypertension and lifestyle changes especially in increasing physical activity and improving diet is effective.

Life style is composed of a chain of active parameters in all dimensions of human life and has a substantial impression on health of population. Since vast majority of health problems has a strong relationship to life style, occurrence of many somatic and psychological disorders would be prevented provided that life style rectified. Blood pressure is one of the most important health criteria moderated when life style has been changed. The aim of this investigation was to study the cause_ effect relationship of life style and blood pressure in administrative employees in Bojnurd rural areas. In this descriptive-analytical (cross sectional) study 380 cases of governmental administrative employees were selected on a stratified random sampling with proportional allocation basis. The Study was conducted on 2012 in Bojnourd city of Iran. Primary data gathering tools were data recording sheet and lifestyle questionnaire. BP ≥ 90/140 were considered as hypertensive. The data analyzed in SPSS software. (V18) The life style in 3 levels of desirable, relatively desirable and undesirable estimated to be 4.58, 52.48 and 42.94 respectively. 7.4% of those studied suffered from high systolic blood pressure and 15.2% had diastolic hypertension. Blood pressure was significantly related to age, weight, height, marital status, exercise, nutrition, stress and body mass index. stress, malnutrition and obesity are among the factors influencing the incidence of hypertension. The essence of implementation of ongoing intervention programs by official bodies to change individual behaviors and lifestyle seems to be required.

Menopause is one of the four crises in women''s life. The purpose of this study is determining the proportion of hypertension and it´s relation with some related factors among post menopausal women from Sari in 2013. In this sectional and Descriptiveanalysisstudy، 301 post menopausal women were recruited using two-steps random sampling method. Simultaneous with screening plan for measuring blood pressure of those people who are above 30 years old across country، this study has been implemented in 10 fixed and mobile health care centers in sari. For recording information، such methods as clinical examination، interview and personal questionnaire have been used. The questionnaire included medical information، social demographic information، blood pressure rate and corresponded factors with blood pressure. For analyzing data،the researcher has used SPSS software version 16، descriptive statistics (frequency، average and standard deviation) and inferential statistics such as chi-square and logistic regression. In this study، 33. 9% of women were afflicted by systolic hypertension. In this study، significant relation between increasing blood pressure with the history of hypertension has been observed (p<0. 0001). Also there has beena significant relation between increasing in systolic blood pressure and lipid، history of myocardial infarction، having more than six children، being above 56 years، and drinking tea at the level of The results of this study show that the prevalenceof systolic hypertension among post menopausal women in sari is relatively high. Moreover، conducting further research for screening menopause women and treatment action has been recommended.

Elevated blood pressure is the major cause of cardiovascular diseases such as stroke، heart failure، and coronary heart disease. The aim of this study was to investigate the effect of hydroalcholic extract of inner seed paddle of walnut on blood pressure of dogs. This study was conducted on six normal adult male dogs. Each dog received (IV) normal saline (as control) and hydroalcholic extract of inner seed paddle of walnut at doses of 5، 15 and 45 mg/kg with 10 min intervals، respectively. Invasive blood systolic and diastolic pressure، were measured simultaneously by a four- channel power-lab device while blood were collected at 15 minutes and 1، 3، and 4 hours after extract and drug administrations to measure plasma Na، K، Ca، aldosterone and renin of the dogs. Normal saline infusion had no effect on these parameters; however، blood pressure of the dogs reduced 15 minutes after extract administration. The increase of direct renin 15 min after extract administration led to drastic decrease of aldosterone to renin ratio (ARR). From the above results it is concluded that the present study seems to support the claims by traditional medicine about usefulness of inner seed paddle of walnut for blood pressure reduction. Further studies on hypertensive animals are warranted to clarify mechanisms involved in blood pressure reduction after extract of inner seed paddle of walnut administration.

Hypertension is a common chronic disease with increasing prevalence worldwide. Regular close monitoring of blood pressure is key point of hypertension management. Home monitoring of blood pressure has its own problems such as lack of early access to a physician in case of emergency. In this study we have designed a device that could send the patient’s self-measured blood pressure to physician. Case report: A 56 year old woman with a 6 year history of hypertension was enrolled to the study. After giving information about using the device، we gave it to her. With each use of device at home we received an SMS (Short Message Service) on patient’s blood pressure that were coordinated with self-recorded blood pressures. This device consisted of a designed electronic board and installed components (such as programmed mobile board and micro controller) placed on the board and attached to a blood pressure measuring device. After pushing a button، the blood pressure was measured spontaneously and data shown on an LED monitor and sent through GSM (Global System for Mobile Communication) by a sim card to the physician. This new device helps physicians to control patients’ blood pressure closely without any extra cost. Also using this device will decrease the rate of complicated hypertensive attacks.

Intracerebral hemorrhage (ICH) is an uncommon but severe complication in pregnant women suffering from hypertension. Most published data support the view that preeclampsia and eclampsia are important risk factors for pregnancy-related ICH. A 26-year-old pregnant, with preeclampsia and lower limb extremities edema on 35-week of first pregnancy admitted in an obstetrician clinical and educational center based on the sonographic finding and underwent cesarean section. She delivered a healthy baby and admitted in emergency room with seizures and intracerebral hemorrhage after four days. The patient was discharged in a healthy condition ten days after drainage of intracerebral hemorrhage by craniotomy. Hypertension treatment during pregnancy prevents serious complications such as ICH. Women with preeclampsia or eclampsia are at higher risk of stroke during pregnancy and in the first postpartum year, in which should be closely monitored even after pregnancy.

High prevalence of obesity is closely associated with a prominent rise in the incidence of hypertension, both of which result in a major increase in cardiovascular disease risk. Several studies also suggest obesity as a major risk factor for systemic inflammation. The purpose of this study was to determine associations between metabolic and anthropometric indicators on the one hand and serum levels of high-sensitivity CRP (hsCRP) and blood pressure in overweight and obese women on the other hand, as well as determine the predictors of hsCRP level and blood pressure in this population. Subjects were recruited by convenience sampling from health care centers and schools in Tehran in winter. From among volunteers 200 women meeting the study criteria were selected and their fasting blood samples collected. Dietary intake was assessed, anthropometric measurements were made, and the related laboratory tests (total cholesterol, triglycerides, glucose, and hsCRP) were performed. Pearson and Spearman correlation coefficients and multiple linear regression were used for statistical analysis. Serum levels of hsCRP were significantly associated with those of glucose(p=0.015, triglycerides (p=0.005), total cholesterol(p=0.002), body mass index (BMI)(<0.0001), waist circumference (WC)(p<0.001), and fat mass (FM) (p<0.0001). Also, systolic blood pressure (SBP) was significantly associated with serum levels of glucose(p=0.018), triglycerides (p=0.011), BMI (p<0.0001), WC(p<0.0001), FM(p=0.005) and WHR(p=0.049). In different regression models, WC and FM were found to be predictors of hsCRP (p= 0.020, 0.015), wheras BMI was a strong predictor of SBP (p <0.0001). This study demonstrates that waist circumference and fat mass are the predictors of hsCRP, while body mass index is the main predictor of systolic blood pressure, in Tehrani obese and overweight women with waist circumference more than 88cm.

Due to controversies in different studies about the effects of dark chocolate consumption on cardiovascular risk factors, this study aimed to review the current evidence on chocolate consumption and cardiovascular risk factors. By the use of dark chocolate, dark chocolate and cardiovascular disease, and dark chocolate and atherosclerosis, as keywords, we searched in PubMed through 1990 till 2008. Just clinical trials on apparently healthy people or those suffering from lipid disorders were included. In most studies, consumption of chocolates with plant sterols induced a reduction in serum total cholesterol and LDL in hypercholesterolemic individuals. Positive effects of dark chocolate on reduction of platelet aggregation has been reported in some investigations while others found neutral effects of white and dark chocolate on platelet aggregation. The effect of dark chocolate intake on insulin sensitivity and reduction of insulin resistance are mentioned in some but not all studies. Dark chocolate consumption significantly reduced blood pressure. A reduction in biomarkers of oxidative stress like 8-isoprostane and MDA has also been reported in some trials. Most of the clinical trials indicated favorable effects of dark chocolate and cocoa consumption on cardiovascular risk factors. More research is needed to identify the related mechanisms of action.

prevalence of hypertension is about 11% among Iranian population. Many factors such as psychological stress, smoking, and type A personality influence the prevalence of hypertension. The purpose of this study was to evaluate type A personality in hypertensive patients. This was a descriptive study. Among 500 patients referring to the cardiology clinics of Sina and Shahid Madani Hospitals in Tabriz, one hundred hypertensive patients were selected by simple sampling method in a period of two months. Demographic data collected and after securing patients` consents, personality questionnaires (TAQ) were filled out. Data entry and analysis performed by means of SPSS statistical software. Fifty males and females were included in this study, mean age were 57±11 and 57±8 for men and women respectively. Systolic blood pressures were in the range of 120-210 mmHg, with a mean value of 157±17.5 Mean blood pressure (BP) was 158/90 mmHg in men and 159/92 mmHg in women accordingly. Prevalence rates of type A and B personalities in hypertensive patients were 54% and 38% respectively which showed a significant statistical difference. This study showed a high prevalence rate of type A personality in hypertensive patients. We recommend assessment of personality type of hypertensive patients and inclusion of supportive psychiatric measures in the treatment of patients with type A personality as an adjunctive treatment for hypertension.
