Integrated Blood Pressure Control最新文献

Atherosclerosis is the primary cause of renal artery stenosis. Atherosclerotic renal artery stenosis (ARAS) is associated with three clinical problems: renovascular hypertension, ischemic nephropathy and cardiac destabilization syndrome which pose huge healthcare implications. There is a significant rate of natural disease progression with worsening severity of renal artery stenosis when renal revascularization is not pursued in a timely manner. Selective sub-groups of individuals with ARAS have had good outcomes after percutaneous renal artery stenting (PTRAS). For example, individuals that underwent PTRAS and had improved renal function were reported to have a 45% survival advantage compared to those without improvement in their renal function. Advances in the imaging tools have allowed for better anatomic and physiologic measurements of ARAS. Measuring translesional hemodynamic gradients has allowed for accurate assessment of ARAS severity. Renal revascularization with PTRAS provides a survival advantage in individuals with significant hemodynamic renal artery stenosis lesions. It is important that we screen, diagnosis, intervene with invasive and medical treatments appropriately in these high-risk patients.

Background: Hypertension is the leading cause of morbidity and mortality among non-communicable diseases. The rate of blood pressure (BP) control among hypertensive patients is poor and the reasons for poor control of BP remain poorly understood globally. Therefore, this study aimed to assess the magnitude and determinants of uncontrolled blood pressure among adult hypertensive patients on follow-up at Nekemte referral hospital (NRH).

Methods: A hospital-based cross-sectional study was conducted from February to April 2018 at NRH. BP control status was determined by the average consecutive BP recordings across the 3 months. The data was entered and analyzed using SPSS version 20.0 and p-value <0.05 was considered statistically significant.

Results: Out of 297 study participants included, the majority were females, 181 (60.9%), and the mean age of the patients was 59.4 ±10.4 years. About half, 137 (46.12%), of the patients had at least one comorbidity and the most common class of anti-hypertensive medication was angiotensin-converting enzyme inhibitors (88.2%). The mean of systolic blood pressure was 132.41± 15.61mmHg, while the mean of diastolic blood pressure was 84.37± 9.32 mmHg. The proportion of participants with optimally controlled BP was 63.6% and 36% were adherent to their medications. Male sex (Adjusted Odd Ratio [AOR]: 1.89, 95% CI: 1.09-4.84), illiteracy (AOR= 1.56, 95% CI: 1.22-6.78), duration of hypertension diagnosis > 10 years (AOR= 2.01, 95% CI: 1.04-16.11), non-adherence (AOR= 3.14, 95% CI: 1.35-10.76) and lack of physical exercise (AOR= 2.8, 95% CI: 1.16-6.74) were positively associated with uncontrolled BP status. Whereas age older than 55 years (AOR= 0.38, 95% CI: 0.11-0.92) was negatively associated with uncontrolled BP.

Conclusion: BP control was relatively achieved in about two-third of pharmacologically treated patients. We recommend better health education and care of patients to improve the rate of BP control status.

Nocturnal hypertension has been recognized as a significant risk factor for cardio- and cerebrovascular diseases. Blood pressure (BP) monitoring significantly increased our awareness of nocturnal hypertension and studies revealed its influence on target organ damage. Nocturnal hypertension is associated with nonphysiological 24-h BP patterns, which consider inadequate drop or even increment of nighttime BP in comparison with daytime BP (nondipping and reverse dipping). Nevertheless, investigations showed that nocturnal hypertension was a predictor of adverse outcome independently of circadian BP pattern. There are still many uncertainties regarding diagnosis, mechanisms and treatment of nocturnal hypertension. There is a small difference between American and European guidelines in cutoff values defining nocturnal hypertension. Pathophysiology is also not clear because many conditions such as diabetes, metabolic syndrome, obesity, sleep apnea syndrome, and renal diseases are related to nocturnal hypertension and nonphysiological circadian BP pattern, but mechanisms of nocturnal hypertension still remain speculative. Therapeutic approach is another important issue and chronotherapy provided the best results so far. There are studies which showed that some groups of antihypertensive medications are more effective in regulation of nocturnal BP, but it seems that the timing of drug administration has a crucial role in the reduction of nighttime BP and conversion of circadian patterns from nonphysiologic to physiologic. Follow-up studies are necessary to define clinical benefits of nocturnal BP reduction and restoring unfavorable 24-h BP variations to physiological variant.

Aim: Correct measurement of blood pressure (BP) is important for optimal diagnosis and treatment of patients with hypertension. The aim of this study was to compare a wrist-worn device using tonometric measurements of BP to a conventional device using oscillometric measurements of 24 h BP, diagnosing of hypertension, and non-dipping.

Methods: One-hundred patients in the Renal Outpatient Clinic had 24 h ambulatory BP monitoring performed with a tonometric device, BPro, and an oscillometric device, A&D, simultaneously.

Results: Twenty-four-hour and daytime systolic BP was significantly lower using tonometric monitoring compared to oscillometric (7 and 6 mmHg, respectively, p< 0.001). In the population of patients diagnosed with hypertension, the tonometric device diagnosed 90% of patients with uncontrolled hypertension correctly (positive predictive value), whereas 49% of patients classified as normotensive were uncontrolled hypertensive (negative predictive value). The mean difference between relative nocturnal BP decrease between tonometric and oscillometric was 2±8% (p< 0.01), and 33% of patients classified as dippers were non-dippers (negative predictive value).

Conclusion: Using the BPro device for tonometric monitoring of BP and classification of hypertension and non-dipping in patients diagnosed with hypertension leads to misclassification of patients. Therefore, the BPro device is not suitable for clinical practice in hypertensive patients from a Renal Outpatient Clinic.

Systemic sclerosis (SSc) is a rare and complex immune-mediated connective tissue disease characterized by multi-organ fibrosis and dysfunction. Systemic sclerosis-associated pulmonary arterial hypertension (SSc-PAH) is a leading cause of death in this population. Pulmonary arterial hypertension (PAH) can coexist with other forms of pulmonary hypertension in SSc, including pulmonary hypertension related to left heart disease, interstitial lung disease, chronic thromboembolism and pulmonary venous occlusive disease, which further complicates diagnosis and management. Available pulmonary arterial hypertension therapies target the nitric oxide, endothelin and prostacyclin pathways. These therapies have been studied in SSc-PAH in addition to idiopathic PAH, often with different treatment responses. In this article, we discuss the management as well as the treatment options for patients with SSc-PAH.

Background: Hypertension and depression are among the most common public health issues affecting the population around the world. Like patients with other chronic medical conditions, hypertensive patients experience many intense emotions which increase their risk for the development of depression. Globally, depression is the leading cause of disability and 382 million people suffer worldwide.

Objective: The aim of this study was to assess the magnitude and factors associated with depression among hypertensive patients attending treatment follow up in the chronic OPD at Hawassa University Comprehensive Specialized Hospital (HUCSH) from March to May, 2019.

Methods: An institutional-based cross-sectional study was conducted with 310 hypertensive patients attending treatment follow up at the chronic Out-Patient Department of HUCSH at Hawassa from March to May, 2019. A validated patient health questionnaire (PHQ-9) was used to assess depression. The data were entered using EPI-data version 3.1 and analyzed in SPSS version 22. Binary logistic regression was used to determine the association of independent variables with dependent variables.

Results: The magnitude of depression among hypertension (HPN) patients was found to be 73 (24.7%). The independent predictors were sex 2.6 (1.16, 5.83), age 11.2 (2.98, 42), educational status, social support 2.55 (1.09, 5.94), family history of depression 7.12 (1.48, 34.26), hypertension 7.57 (2.67, 21.44), and medication adherence 11.6 (4.23, 31.78).

Conclusion: The magnitude of depression among HPN patients was high. So, continuous health information dissemination at a different level regarding factors affecting them should be given. Strengthening a referral linkage with a psychiatric unit for psycho-behavioral therapy will bring good clinical outcome. Besides, controlling hypertension was crucial to bring good clinical outcome.

Background: Self-monitoring of blood pressure (BP) among hypertensive patients is an important aspect of the management and prevention of complication related to hypertension. However, self-monitoring of BP among hypertensive patients on scheduled follow-up in hospitals in Ethiopia is unknown. The aim of the study was to assess knowledge and attitude of self-monitoring of BP among adult hypertensive patients.

Methods: A cross-sectional survey was conducted on 400 adult hypertensive patients attending follow-up clinics at four public hospitals of Arsi Zone, Oromia Regional State, Ethiopia. The data were collected from patients from March 10, 2019 to April 8, 2019 by face-to-face interview using a pretested questionnaire and augmented by a retrospective patients' medical records review. The data were analyzed using the SPSS version 21.0 software.

Results: A total of 400 patients were enrolled into the study with the response rate of 97.6%. The median age of the participants was 49 years (range 23-90 years). More than half (225 [56.3%]) were male. The majority (160 [40%]) were married and more than two-thirds (282 [70.5%]) were Oromo by ethnic background. About 206 (51.5%) had attended primary education. The proportion of patient's knowledge toward self-monitoring of BP and the practice of self-monitoring of BP among hypertensive patients was 31.5% (n=126 [95% CI; 26.5, 36.5]) and 7.75% (n=31 [95% CI; 5.3, 10.5]) respectively. The multivariable logistic regression analysis revealed; higher education (AOR=2.73, 95% CI [1.33, 13.88)], governmental employed (AOR=1.52, 95% CI [1.06, 6.48]), having an income of >3500 Ethiopian Birr (AOR=2.16, 95% CI [1.56, 7.39]), duration of hypertension >6 years (AOR=1.87, 95% CI [1.21, 6.37]), having health insurance (AOR=3.56, 95% CI [1.39, 10.53]), having co-morbidities (AOR=3.93, 95% CI [1.35, 10.32]), receiving a health professional recommendation toward self-monitoring of BP (AOR=6.08, 95% CI [2.45, 15.06]), and having an awareness of hypertension-related complication (AOR=3.94, 95% CI [1.34, 11.44]) were factors significantly associated with self-monitoring of BP.

Conclusion: In this study, the proportion of knowledge of self-monitoring of BP and the practice of self-monitoring of BP among hypertensive patients on follow-up were low. Educational programs on self-monitoring of BP including teaching through demonstration may be needed to be in place.

Hyperuricemia has long been recognized to be associated with increased cardiovascular risk, including risk of developing hypertension. Epidemiological findings suggest that the link with hypertension is stronger in children and adolescents. Uric acid acts as a strong antioxidant compound in the extracellular environment but has pro-inflammatory effects within the intracellular setting. A chronic phase of microvascular injury is known to occur after prolonged periods of hyperuricemia. This is proposed to contribute to afferent arteriolopathy and elevation of blood pressure that may become unresponsive to uric acid-lowering therapies over time. Studies have struggled to infer direct causality of hyperuricemia due to a vast number of confounders including body mass index. The aim of this review is to present the available data and highlight the need for large scale prospective randomized controlled trials in this area. At present, there is limited evidence to support a role for uric acid-lowering therapies in helping mitigate the risk of hypertension.

Purpose: The leaves of the Khat plant contain amphetamine-like compounds which are implicated in the development of hypertension. The increase in blood pressure coincides with the plasma cathinone level. Other factors associated with hypertension are being overweight, obesity, cigarette smoking, alcohol use, physical inactivity, unhealthy diet, and stress. Thus, this study assessed the association of chronic khat chewing with hypertension and other factors associated with hypertension.

Patients and methods: Acommunity based comparative cross-sectional study was undertaken from October 5, 2018 to February 15, 2019 in Gurage zone, southern Ethiopia. A total of 1200 adults (600 chewers and 600 non-chewers) aged 18 - 65 years were selected using a convenience sampling method. The data was collected by an interviewer-administered questionnaire plus physical measurements and were carried out at a fixed time of the day in the morning (7: 00 am-10:00 am). Linear regression and binary logistic regression analysis were performed to identify the determinant factors of blood pressure. The test of statistically significant association was declared by using 95% CI and p-value less than 0.05.

Results: A total of 1198 adults participated in the study giving a response rate of 99.8%. The mean age of Khat chewers were 34 (± 11.27) and non-chewers were 34.73 (± 11.48) years. The mean values of systolic blood pressure and diastolic blood pressure were higher in chewers than in non-chewers (p < 0.001). The prevalence of diastolic blood pressure > 80mmHg was significantly higher among Khat chewers than in non-chewers (17.4% versus 8.7%, p < 0.001). The duration of Khat chewing was significantly associated with systolic blood pressure (Beta coefficient = 0.83, p < 0.001) and diastolic blood pressure (Beta coefficient = 0.51, p < 0.001). The sex, age, BMI and alcohol were significantly associated with both systolic and diastolic blood pressure.

Conclusion: Chronic Khat chewing, male sex, BMI and alcohol were associated with increased systolic and diastolic blood pressure. To assess the cause and effect relationship between chronic Khat chewing and hypertension further studies with better defined cohorts and basic science studies need to be undertaken.

Background: Older adults are disproportionately affected by hypertension, which is an established risk factor for cardiovascular disease. Despite these facts, little information is available with regard to old age hypertension in Ethiopia. Thus, this study assessed old age hypertension and associated factors among older adults in rural Ethiopia.

Methods: A community-based cross-sectional study design was employed among 418 selected permanent residents of Chiro town aged 50 years and older using simple random sampling technique. Data were collected face to face using a structured questionnaire which is adapted from the WHO Stepwise approach to surveillance of non communicable disease instrument, and was used to collect data on risk factors. Physical measurements were taken as per WHO STEP guidelines. The data were entered into Epi Data version 3.1 and exported to SPSS Version 20 for analysis. Bivariate and multivariable logistic regression analysis were conducted and statistical significance was declared at a p-value ≤0.05.

Results: The overall prevalence of old age hypertension was 41.9% (95% CI: 37.2-46.6). Age ≥70 years (AOR: 1.91; 95% CI: 1.12-3.27), low intake of fruits (AOR: 2.45; 95% CI: 1.55-3.86), overweight/obese (AOR: 4.29; 95% CI: 2.48-7.42) and family history of hypertension (AOR: 2.95; 95% CI: 1.70-5.12) were significantly associated risk factors of hypertension.

Conclusion: The prevalence of hypertension among older adults was high. Older age ≥70 years, low intake of fruits, overweight/obese and having a family history of hypertension were significantly associated with hypertension. Consideration should be given for community-based screening of hypertension among older adults. In addition, fruit consumption habits and maintaining normal weight should be encouraged.
