Abstract: Hypertension is one of the most well-established risk factors for atrial fibrillation. Long-standing untreated hypertension leads to structural remodeling and electrophysiologic alterations causing an atrial myopathy that forms a vulnerable substrate for the development and maintenance of atrial fibrillation. Hypertension-induced hemodynamic, inflammatory, hormonal, and autonomic changes all appear to be important contributing factors. Furthermore, hypertension is also associated with several atrial fibrillation-related comorbidities. As such, hypertension may represent an important target for therapy in atrial fibrillation. Clinicians should be aware of pitfalls of the blood pressure measurement in atrial fibrillation. While the auscultatory method is preferred, the use of automated devices appears to be an acceptable method in the ambulatory setting. There are pathophysiologic bases and emerging clinical evidence suggesting the benefit of renin-angiotensin system inhibition in risk reduction of atrial fibrillation development particularly in patients with left ventricular hypertrophy or left ventricular dysfunction. A better understanding of hypertension’s pathophysiologic link to atrial fibrillation may lead to the development of novel therapies for the primary prevention of atrial fibrillation. Finally, future studies are needed to address optimal blood pressure goal to minimize the risk of atrial fibrillation-related complications.

Abstract: Blood pressure (BP) responses are controlled by various factors and understanding how BP changes is important to occupational health. This paper presents a review of the literature which reports BP responses in the firefighter population. Hypertension is one of the main risk factors underlying the pathophysiology of cardiovascular disease (CVD), and cardiac incidents remain the leading cause of line-of-duty deaths in firefighters. Risk factors for line-of-duty deaths include obesity, previous or underlying heart disease, and hypertension. The occupation of firefighting is one of the most hazardous and dangerous jobs, yet over 50% of firefighters are volunteers. Tactical operations and the hazardous nature of firefighting are exposures that influence stress responses and therefore affect BP. In fact, hypertension in firefighters often remains undocumented or undiagnosed. CVD risk and elevated BP in tactical populations, like firefighters, may be a combination of physical and emotional stress due to the nature of the job. Cross-sectional studies have reported that firefighters have higher levels of BP and higher rates of hypertension compared to civilians. Interestingly, there is a limited amount of research that reports BP values before and after firefighting-related activities, and very few studies that report on interventional changes in BP. Here we synthesize the literature on firefighting and provide a summary of the studies that report pre- and post- BP levels that relate to CVD risk factors, occupational factors, firefighting activities, and the data on exercise training and BP. More studies are needed that examine BP in firefighters and that report on the changes in BP with occupational activities.

Background: Polymeric nanomaterials with size ranging from 10 to 1000 nm are one of the most widely used types of nanoparticles with ideal properties in the drug delivery systems. Here, we decided to systematically review the antihypertensive effects of polymeric nanomaterials in vitro, in vivo, and clinical trials. Methods: The present review was conducted based on the 06- PRISMA guideline; whereas five English databases, including Scopus, PubMed, Web of Science, EMBASE, and Google Scholar without time limitation were used for searching the publications related to antihypertensive effects of natural and synthetic polymeric nanoparticles. Results: The results demonstrated that among 1701 papers, 25 papers including 11 in vitro (44%), 6 in vivo (24%), 7 in vitro / in vivo (28%), and 1 in vitro / ex vivo (4%) up to 2020, met the inclusion criteria for discussion in this systematic review. The most used nanoparticles poly-(lactic-co-glycolic) acid nanoparticle (PLGANPs) (7, 29.2%), chitosan based nanoparticles (6, 25%), followed by polylactide acid nanoparticles (5, 20.8%). Conclusion: We concluded that the high potency of polymeric nanoparticles in the drug delivery system for hypertension treatment. Although the accurate mechanisms are not fully understood; however, some mechanisms such as sustained release forms with increased bioavailability, increasing oral bioavailability and improve the oral and non-oral absorption, counteracting excessive superoxide and decreasing blood pressure, etc can be related these nanoparticles.
