Ivabradine and metoprolol differentially affect cardiac glucose metabolism despite similar heart rate reduction in a mouse model of dyslipidemia
This study aimed at testing whether similar HRR with ivabradine vs. metoprolol differentially modulates cardiac energy substrate metabolism, a factor determinant for cardiac function, in a mouse model of dyslipidemia (hApoB+/+;LDLR–/–). Following a longitudinal study design, we used 3- and 6-mo-old mice, untreated or treated for 3 mo with ivabradine or metoprolol. Cardiac function was evaluated in vivo and ex vivo in working hearts perfused with 13C-labeled substrates to assess substrate fluxes through energy metabolic pathways. Compared with 3-mo-old, 6-mo-old dyslipidemic mice had similar cardiac hemodynamics...

Sudden cardiac death in transposition of the great arteries with a Mustard or Senning baffle: the myocardial ischemia hypothesis
Purpose of review: The literature on sudden death in transposition of the great arteries (D-TGA) with atrial switch surgery is reviewed and a pathophysiological mechanism is proposed. Recent findings: Over 80% of sudden deaths in patients with D-TGA and Mustard or Senning baffles occur during exercise. Factors most consistently associated with ventricular arrhythmias and sudden death include heart failure parameters and atrial arrhythmias. Atrial arrhythmias have been observed to trigger malignant ventricular arrhythmias. Exercise may promote 1 : 1 conduction, with inordinately high ventricular rates. Reconstructed in...

Beta-blockers for hypertension.
CONCLUSIONS: Most outcome RCTs on beta-blockers as initial therapy for hypertension have high risk of bias. Atenolol was the beta-blocker most used. Current evidence suggests that initiating treatment of hypertension with beta-blockers leads to modest CVD reductions and little or no effects on mortality. These beta-blocker effects are inferior to those of other antihypertensive drugs. Further research should be of high quality and should explore whether there are differences between different subtypes of beta-blockers or whether beta-blockers have differential effects on younger and older people.

Results of the STOP-Hypertension-2 Trial.
Authors: Hansson L Abstract The second Swedish Trial in Old patients with Hypertension (STOP-Hypertension-2) was conducted to compare the effects of 'newer( antihypertensive therapies (angiotensin converting enzyme [ACE] inhibitors and calcium antagonists) and established therapies (beta-blockers and diuretics) on cardiovascular mortality and morbidity in elderly hypertensive patients. A total of 6614 patients were randomized to receive conventional treatment, ACE inhibitors or calcium antagonists, and followed for a mean of 5 years. The primary endpoint was a combination of fatal stroke, fatal myocardial infarctio...

Beta-blockers 'useless' for many heart attack patients, study reports
Conclusion This study aimed to see whether beta blockers reduce mortality in people who've had a heart attack but who don't have heart failure or systolic dysfunction. It found no difference between those who were and those who were not given beta-blockers on discharge from hospital. The authors say this adds to the evidence that routine prescription of beta blockers might not be needed for patients without heart failure following a heart attack. Current UK guidelines recommend all people who have had a heart attack take beta blockers for at least one year to reduce risk of recurrent events. Only people with heart failure ...

Management and clinical outcome of stable coronary artery disease in Austria : Results from 5  years of the CLARIFY registry.
CONCLUSION: Characteristics of Austrian outpatients with stable CAD corresponded to those of patients with CAD in other developed countries. Medical treatments following the recommendations of the European guidelines were prescribed in the majority of patients; however, recommended goals of life style interventions including a heart rate less than 60 bpm and general risk factor management were not achieved by a high proportion of patients. Heart rate control and life style changes remain unmet needs of cardiovascular care in Austria. PMID: 28913755 [PubMed - as supplied by publisher]

Cardiovascular risk factors in patients with combined central retinal vein occlusion and cilioretinal artery occlusion: Case report
AbstractRationale:To analyze cardiovascular risk factors and comorbidity of acute unilateral visual loss due to combined central retinal vein occlusion (CRVO) and cilioretinal artery occlusion (CLRAO).Patient concerns:Among patients with retinal vein or artery occlusion hospitalized at the Department of Ophthalmology between January 2011 and August 2017, subjects with combined CRVO/CLRAO were selected. All of them underwent ophthalmologic and cardiologic examination, including fluorescein angiography, optical coherence tomography, 12-lead electrocardiogram, transthoracic and transesophageal echocardiography, carotid Dopple...

Featured Review: First-line drugs for hypertension
Thiazides best first choice for hypertensionHigh blood pressure or hypertension can increase the risk of heart attacks and stroke. One of the most important decisions in treating people with elevated blood pressure is what drug class to use first. This decision has important consequences in terms of health outcomes and cost.TheCochrane Hypertension Group, which is part ofCochrane Circulation and Breathing, updated their original 2009 Cochrane Review looking at what drug class was the best first-line choice in treating adult patients with raised blood pressure. No new trials were found in the update; keeping the total at 24...

Sex-Mediated Response to the Beta-Blocker Landiolol in Sepsis: An Experimental, Randomized Study
Conclusions: Landiolol improved the in vivo cardiac performance of septic male rats while deleterious effects were reported in females. Expression of natriuretic peptide receptor 3, phosphorylated-AKT:AKT, and endothelial nitric oxide synthase are signaling pathways to investigate to better understand the sex differences in sepsis.

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}

Beta-blockers in hypertension: overview and meta-analysis of randomized outcome trials
Conclusion: Compared with other antihypertensive agents, beta-blockers appear to be substantially less protective against stroke and overall mortality. However, they exhibit a substantial risk-reducing ability for all events when prescribed to lower BP in patients with modest or more clear BP elevations, and therefore can be used as additional agents in hypertensive patients.
