Cost Effectiveness of Strategies to Manage Atrial Fibrillation in Middle- and High-Income Countries: A Systematic Review
ConclusionThis systematic review has shown that there are several cost-effective strategies to manage AF in different resource settings. However, the decision to use any strategy should be guided by objective clinical and economic evidence supported by sound clinical judgement.RegistrationCRD42022360590.

Blunted cardiovascular effects of beta-blockers in patients with cirrhosis: Relation to severity?
ConclusionWe found the effect of beta-blockade on cardiac index in patients with advanced cirrhosis to be less potent than in patients with early cirrhosis, indicating that underlying cirrhotic cardiomyopathy increases, and the cardiac compensatory reserve becomes more compromised, with disease progression. The differential effects of beta-blockade in the left atrium may be used to predict the effect of beta-blockers on portal pressure, but further studies are needed to investigate this possibility.

Transdermal opioid patch in treatment of paroxysmal autonomic instability with dystonia with multiple cerebral insults: A case report
Rationale: Paroxysmal autonomic instability with dystonia (PAID) is an underdiagnosed syndrome that describes a collection of symptoms following diverse cerebral insults, such as traumatic brain injury, hydrocephalus, hemorrhagic stroke, or brain anoxia. It is manifested by systemic high blood pressure, hyperthermia, tachycardia, tachypnea, diaphoresis, intermittent agitation, and certain forms of dystonia. Patient concerns: A semi-comatose 46-year-old man was transferred from the regional rehabilitation hospital with various complaints involving fluctuating vital signs, including uncontrolled hyperthermia, hypertensi...

Thyrotoxicosis and bilateral internal carotid artery dissections
Cervical artery dissection is a rare but important diagnosis to consider in young patients presenting with stroke. Multiple etiologies of cervical artery dissections have been previously reported, but the association with thyrotoxicosis is extremely rare. A previously healthy 43-year-old female presented to the emergency department with new symptoms related to thyrotoxicosis and bilateral internal carotid artery dissections. Her atrial fibrillation and hypertension resolved by treating the underlying hyperthyroidism with methimazole and propranolol.

Qing-Kai-Ling Injection Induces Immediate Hypersensitivity Reaction via the Activation of Anaphylatoxin C3
Conclusion: QKLI-IHR is complement activation-related pseudoallergy, rather than an IgE-mediated allergy. QKLI activates C3 and might consequently provoke mast cells to release histamine, which is a principal effector of its IHR. The pseudoallergic reaction induced by QKLI was attributed to the extract of Isatidis Radix. This study suggests a potential therapeutic strategy for the prophylaxis and treatment of QKLI-IHR.

Testing the Translational Power of the Zebrafish: An Interspecies Analysis of Responses to Cardiovascular Drugs
The zebrafish is rapidly emerging as a promising alternative in vivo model for the detection of drug-induced cardiovascular effects. Despite its increasing popularity, the ability of this model to inform the drug development process is often limited by the uncertainties around the quantitative relevance of zebrafish responses compared with non-clinical mammalian species and ultimately humans. Here we provide a comparative quantitative analysis of the in vivo cardiovascular responses of zebrafish, rat, dog, and human to three model compounds (propranolol, losartan, and captopril), which act as modulators of two key systems ...

Biux2x2
Conclusions: Brown fat tissue is a normal variant in pediatric F-18 FDG studies. This diffuse activity can frustrate the radiologist reading the study and possibly cause a misdiagnosis. Propranolol may be a promising solution to reducing the brown fat in pediatric patients undergoing a F-18 FDG PET/CT scan. p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 16.0px Helvetica; -webkit-text-stroke: #000000} span.s1 {font-kerning: none} p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 16.0px Helvetica; -webkit-text-stroke: #000000} span.s1 {font-kerning: none}

Is Aberrant Reno-Renal Reflex Control of Blood Pressure a Contributor to Chronic Intermittent Hypoxia-Induced Hypertension?
This study demonstrated unaltered vascular conductance in response to lumbar sympathetic stimulation in CIH-exposed rats. Aortic compliance was increased and estimated blood volume was unchanged in CIH-exposed rats. Increased blood pressure was related to an increase in cardiac output, which was confirmed by echocardiography (Lucking et al., 2014). It is suggested therefore that hypertension in the CIH model can be evoked by over-excitation of the cardiac arm of sympathetic nervous system (SNS), even before mechanisms of enhanced peripheral vasoconstriction and endothelial dysfunction are initiated (Naghshin et al., 2009)....

Electrochemical determination of antihypertensive drugs by employing costless and portable unmodified screen-printed electrodes.
Abstract Hypertension increases the risk of heart disease and stroke, is commonly known as a silent killer disease and considered as one of the key risk factor for premature death and disability over the world. Herein, we report for the first time a sensitive, costless and reproducible voltammetric method for individual determination of five antihypertensive drugs namely, propranolol (PRO), timolol (TIM), amlodipine (AML), amiloride (AMI) and triamterene (TRI) using differential pulse voltammetry at bare/unmodified screen-printed carbon electrodes (SPEs) in presence of sodium dodecyl sulfate (SDS). Each drug exhib...

Open resection and laryngotracheal reconstruction in a case of subglottic hemangioma in PHACE syndrome
We describe a 1 month old infant with PHACE syndrome who underwent successful management of subglottic hemangioma by open resection and laryngotracheal reconstruction using a thyroid ala graft. Propranolol is typically the treatment of choice for subglottic hemangiomas however, recent reports have suggested adverse complications with the use of propranolol in children with PHACE syndrome. The child had cerebral and cervical vascular anomalies associated with her PHACE syndrome making her at an increased risk of stroke with the use of propranolol.

Pharmacotherapy for hypertension in adults aged 18 to 59 years.
CONCLUSIONS: Antihypertensive drugs used to treat predominantly healthy adults aged 18 to 59 years with mild to moderate primary hypertension have a small absolute effect to reduce cardiovascular mortality and morbidity primarily due to reduction in cerebrovascular mortality and morbidity. All-cause mortality and coronary heart disease were not reduced. There is lack of good evidence on withdrawal due to adverse events. Future trials in this age group should be at least 10 years in duration and should compare different first-line drug classes and strategies. PMID: 28813123 [PubMed - as supplied by publisher]

An Exploratory Study in Healthy Male Subjects of the Mechanism of Mirabegron-Induced Cardiovascular Effects.
Abstract To explore the role of β1 -adrenoceptors (ARs) in the heart rate response to the selective β3 -adrenoceptor agonist mirabegron, 12 young male volunteers received single oral doses of the nonselective β1/2 -AR antagonist propranolol (160 mg), the selective β1 -AR antagonist bisoprolol (10 mg), or placebo on days 1 and 5 of each period in a 3-period crossover study. On day 5, dosing was followed by a supratherapeutic dose of mirabegron (200 mg). Vital signs, impedance cardiography, and plasma renin activity were collected. Mirabegron increased heart rate and systolic blood pressure and reduced stroke vo...
