  • Survival in South Asian and White European patients after acute myocardial infarction: new evidence of heterogeneity
    Raj S Bhopal

    Dear Editor Gholap et al confirmed a surprising observation that South Asians, compared to White British populations, have lower or similar, rather than higher mortality, following myocardial infarction, as Fischbacher et al first demonstrated in Scotland.(1;2) As the chief investigator of that Scottish study I found the result perplexing given South Asians' high prevalence of type 2 diabetes. A literature review showed...

  • Paradoxical low-flow low-gradient aortic stenosis: advanced severe disease, a new entity or a progression of disease?
    Calvin WL Chin

    I read the research by Dahl et al. with great interest (1). The authors have suggested paradoxical low-flow low-gradient aortic stenosis is a distinct entity, and not an advanced stage of severe aortic stenosis. Indeed, they have observed only 5% of these patients had high-gradient severe disease prior to the index assessment (1).

    Recent studies have demonstrated that paradoxical low-flow low- gradient is a hete...

  • Re:Comment on: An epidemiological appraisal of the association between heart rate variability and particulate air pollution: a meta-analysis
    Tim S. Nawrot

    We thank Buteau and colleague (Buteau et al. 2014) for their interest in our meta-analysis on Heart Rate Variability (HRV) and air pollution (Pieters et al. 2012). Their concern about combining studies from different types of regression models ignores the strength of our meta -analysis to combine all the available evidence on HRV and air pollution published before February 2012. Combining the available evidence is criti...

  • Coffee brewing technique as a confounder in observational studies
    Christopher D Hingston

    Choi and colleagues describe an association between moderate coffee consumption and lower prevalence of subclinical coronary atherosclerosis [1]. This is consistent with a growing body of evidence that supports this finding. A similar large prospective study of over 400 000 participants, demonstrated that coffee consumption was inversley associated with both total and cause-specific mortality, specifically heart disease [...

  • Air pollution and cardiovascular disease
    Tomoyuki Kawada

    I read a paper by Xie et al. with interest (1). There is also a review article in the same issue by Chin on the mechanism on the relationship between air pollution and cardiovascular events (2), and expert position paper was also published (3). Xie et al. handled large samples in Beijing and conducted their survey with special emphasis on fine particulate matter (PM2.5) concentration and ischaemic heart disease (IHD) mo...

  • Lower heart rate better in early AF
    Akshay k MEHTA

    Since the study shows a lower heart rate in paroxysmal or persistent AF is associated with lesser chance of progression to permanent AF, would rigorous treatment of heart rate with beta blockers in paroxysmal or persistent AF reduce the chance of their progression to permanent AF ?

    Conflict of Interest:

    None declared

    Inigo Lozano

    We have read with great interest the article written by Zhang et al[1] and we want to congratulate the authors on his contribution in this relevant issue. Since the first publication in 1995 by Pijls et al, fractional flow reserve has constantly progressed with undoubted success. After initially being validated as alternative to the non-invasive tests, the DEFER trial showed that a strategy of PCI based in FFR achieves b...

  • Re:"Type 2" myocardial infarction: Evidence-based or guesswork diagnosis
    Tomasz Baron

    We would like to thank Dr Y-Hassan for his valuable comments [1] on our manuscript on type 2 myocardial infarction (AMI) [2]. As pointed out in our article we share Dr Y-Hassan?s criticism against the vague diagnostic criteria for type 2 AMI in the Universal Definition of Myocardial Infarction [3,4] It may be difficult in many cases to distinguish type 2 AMI from type 1 AMI and other non-ischaemic conditions associated...

  • Where are the Surgeons? A Safety Opportunity Missed
    Stephen Clark

    The introduction of a Patient Safety Checklist is a welcome addition for interventional cardiologists and is a concept practiced by surgeons in all disciplines for a number of years since the original WHO Patient Safety Checklist was proven to be of benefit in a global and multidisciplinary setting (1). The European Association for Cardiothoracic Surgery embraced this ideal in 2012 (1) with the publication of safety check...
