Salt not as damaging to health as previously thought, says study

New research reignites a row with scientists who want to reduce salt intake to near zeroSalt may not be as damaging to health as is usually claimed, according to a controversial new study which suggests campaigns to persuade people to cut down may only be worthwhile in countries with very high sodium consumption, such as China.The World Health Organization recommends cutting sodium intake to no more than 2g a day – the equivalent of 5g of salt – because of the link to increased blood pressure, which is in turn implicated in stroke.Continue reading...

Publication date: Available online 15 December 2018Source: Canadian Journal of CardiologyAuthor(s): Derrick Y. Tam, Faisal Bakaeen, Dmitriy N. Feldman, Philippe Kolh, Gaetano Antonio Lanza, Marc Ruel, Raffaele Piccolo, Stephen E. Fremes, Mario FL. GaudinoAbstractThe management of severe left main (LM) disease remains controversial and continues to evolve as new evidence emerges. Patient selection for CABG or PCI relies on both predicting mortality with CABG from clinical characteristics using the Society of Thoracic Surgeons risk score and anatomical complexity using the SYNTAX score. LM stenting techniques continue to evo...

Abstract Atherosclerosis is the underlying cause of most myocardial infarction (MI) and ischaemic stroke episodes. An early sign of atherosclerosis is hypertrophy of the arterial wall. It is known that increased intima media thickness (IMT) is a non-invasive marker of arterial wall alteration, which can easily be assessed in the carotid arteries by high-resolution B-mode ultrasound. Similarly, the other key element of MI and ischaemic strokes is the N-methyl-D-aspartate (NMDA) receptor which is an ionotropic glutamate receptor that mediates the vast majority of excitatory neurotransmission in the brain. NMDA activ...

At this year's RAADfest event, the interviewer noted here was taking an informal survey of optimistic versus pessimistic attitudes towards progress in the decades ahead. Apparently I was on the pessimistic end of the spectrum. Once past the present highly active development of senolytic therapies to remove senescent cells from old tissues, I think it quite plausible that we'll see a gap of a decade before the next class of SENS-like rejuvenation therapy arrives at the point of availability via medical tourism. The likely candidates include clearance of cross-links and restoration of the immune system via thymic regrowth. ...

Authors: Miao CQ, Lu Q, Liu P, Bai L, Qu H, Ma AQ Abstract OBJECTIVE: Nardilysin (N-arginine dibasic convertase, NRDC) is a kind of metalloendopeptidase associated with several inflammatory diseases. NRDC is reported to be eligible for early detection of acute coronary syndrome. However, the availability and effectiveness of NRDC in predicting the prognosis of patients with ST-elevation myocardial infarction has never been investigated. PATIENTS AND METHODS: From January 2010 to January 2012, the prospective observational cohort study enrolled a total of 396 STEMI patients, who were sampled with blood within 24...

The latest estimate of attributable deaths to pollution worldwide is extraordinary: 9 million deaths annually [2]. Deaths are related to cardiovascular disorders (myocardial infarction, congestive heart failure and stroke), lung diseases and cancers. The recent Global Burden of Disease study, based on 1990 –2013 data from 188 countries demonstrated that air pollution contributes to 29.2% of the global burden of stroke. However the burden varies between 10% in high-income countries and 34% in low- and middle-income countries [3].

Dronedarone is the newest available oral antiarrhythmic drug (AAD). In a paper by Ehrlich et al. [1] accompanying this editorial the authors report on risks for myocardial infarction (MI) and stroke in AF patients given a first prescription for dronedarone, amiodarone, flecainide, propafenone, or sotalol in 1258 general and 62 cardiology practices between January 2010 and March 2017. They attempt to compare MI and stroke risks in dronedarone patients (n  = 3498) versus those treated with all the other stated antiarrhythmic drugs (AAD) analyzed in combination (n = 17,724).

CONCLUSIONS: The advantages of bivalirudin are undoubtedly related to GPI use in the heparin arms. Bivalirudin-based regimens are more beneficial when compared with heparin and planned GPI use in terms of NACE and major bleedings; this was not observed when compared to heparin and provisional GPI use. Regardless of adjunctive GPI use, stent thrombosis episodes were significantly more common in bivalirudin-treated subjects. Therefore, the safety and economic issues may urge revision of this aspect of current clinical practice and guidelines. PMID: 29350380 [PubMed - indexed for MEDLINE]

Abstract BACKGROUND: Circulating microRNAs (miRs) levels are potentially important diagnostic and prognostic biomarkers in acute coronary syndrome (ACS) or cerebral ischaemic events (CIE) resulting from internal carotid artery stenosis (ICAS). AIM: This four-year prospective study aimed to compare the levels of circulating miRs in ACS vs. CIE patients, and investigate miRs potentially associated with risk of recurrent cardiovascular events. METHODS: The circulating miRs levels (miR-1-3p, miR-16-5p, miR-34a-5p, mir-122-5p, miR-124-3p, miR-133a-3p, miR-133b, miR-134-5p, miR-208b-3p, miR-375, and miR-499-5p...
