(Press-News.org) London, UK - 30 Aug 2015: Young adults living in a polluted city show early signs of cardiovascular risk, according to research presented at ESC Congress today by Dr Krzysztof Bryniarski from Jagiellonian University, Collegium Medicum in Krakow, Poland.1 Residing in a polluted city was associated with higher levels of inflammatory markers in otherwise healthy adolescents and young adults, which indicate a greater risk of having a heart attack in future.
Dr Bryniarski said: "This study was conducted by a group of medical students from Jagiellonian University in Krakow, supervised by Professors T. Guzik and A. Wysokinski, who wanted to know what impact long term air pollution is having on the cardiovascular health of young adults. Krakow is one of the most polluted cities in Europe. We decided to compare some markers of cardiovascular risk in our city with risk in Lublin, which has similar general demographic characteristics but much lower traffic congestion and two fold lower air pollution."
The current study assessed the association between long term air pollution exposure and blood pressure and inflammatory markers in Krakow and Lublin, two large Polish cities each with more than 300 000 inhabitants. It included 826 randomly selected healthy young adults aged 16 to 22 years (average age 18), of whom 444 lived in Krakow and 382 lived in Lublin. Participants came from similar types of schools and social backgrounds and had lived in their home city since birth.
The researchers measured blood pressure, heart rate and blood levels of inflammatory markers including C-reactive protein (CRP), high sensitivity CRP (hsCRP), homocysteine and fibrinogen which are early indicators of cardiovascular disease. They also assessed numerous potential confounding factors such as body mass index (BMI), lifestyle, ethnicity and family history.
Data on air pollution was obtained from air quality monitoring stations. Average 10 year air pollution levels were nearly double in Krakow compared to Lublin. Average PM2.5 levels for example were 41.7 µg/m3 in Krakow and 22.4 µg/m3 in Lublin while PM10 was 56.9 µg/m3 in Krakow and 29.4 µg/m3 in Lublin.
The investigators found significantly higher levels of CRP, hsCRP, homocysteine and fibrinogen levels in Krakow residents compared to Lublin residents (p END

Cold weather associated with higher risk of severe heart attack
2015-08-30
London, UK - 30 Aug 2015: Cold weather is associated with a higher risk of severe heart attack, according to research presented at ESC Congress today by Dr Shuangbo Liu, adult cardiology resident at the University of Manitoba in Winnipeg, Canada.1 The six year study found that each 10°C drop in temperature was associated with a 7% increased risk of ST-elevation myocardial infarction (STEMI), the most severe form of heart attack.
"We studied the effects of temperature on the risk of heart attacks in Winnipeg, Canada, one of the coldest large cities in the world," said ...
CPR for out-of-hospital cardiac arrest should be conducted for at least 35 minutes
2015-08-30
London, UK - 30 Aug 2015: Cardiopulmonary resuscitation (CPR) for out-of-hospital cardiac arrest should be conducted for at least 35 minutes, according to research presented at ESC Congress today by Dr Yoshikazu Goto, associate professor and director of the Department of Emergency and Critical Care Medicine at Kanazawa University Hospital in Kanazawa, Japan.1 The study in more than 17 000 patients found that nearly all survivals were achieved within 35 minutes and longer CPR achieved little benefit.
Dr Goto said: "The decision regarding when to stop resuscitation efforts ...
Cold weather linked to increased stroke risk in atrial fibrillation patients
2015-08-30
London, UK - 30 Aug 2015: Cold weather is associated with increased risk of ischaemic stroke in patients with atrial fibrillation, according to research presented at ESC Congress today by Dr Tze-Fan Chao, cardiologist at Taipei Veterans General Hospital and the National Yang-Ming University in Taiwan.1 The study in nearly 290 000 patients suggests that cool climate may be an underrated issue for health that deserves more attention.
"Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and it increases the risk of ischaemic stroke by four- to five-fold," ...
Treating left atrial appendage could dampen long standing persistent AF
2015-08-30
LONDON, UK - In patients with long-standing persistent atrial fibrillation (AF) despite standard treatment, additional electrical isolation of an area called the left atrial appendage (LAA) can improve freedom from AF without increasing complications, results of the BELIEF study show.
The findings were presented today in a Hot Line session at ESC Congress 2015.
"Empirical left atrial appendage isolation, along with the standard approach of pulmonary vein isolation (PVI) and ablation of extra-pulmonary triggers is superior to the standard approach alone in enhancing the ...
Patient education does not impact apixaban adherence
2015-08-30
LONDON, UK - Adherence to the oral anticoagulant apixaban among patients with atrial fibrillation (AF) was no better for those who received an educational program compared to those who did not, results of the international, randomised AEGEAN trial show.
The results, presented today at ESC Congress 2015, were nevertheless "quite encouraging," according to lead investigator Gilles Montalescot, MD, PhD, from the Institut de Cardiologie, Centre Hospitalier Universitaire Pitié-Salpêtri?re, in Paris, France.
"We used the best possible tools for the educational program, ...
Adenosine triphosphate does not improve efficacy of pulmonary vein isolation
2015-08-30
LONDON, UK - Late recurrence of atrial fibrillation (AF) is not reduced in patients whose pulmonary vein isolation (PVI) treatment incorporates the addition of adenosine triphosphate (ATP), according to results of the UNDER-ATP trial.
Results of the trial, presented at ESC Congress 2015, add to the ongoing debate about ATP use in this setting.
The major cause of AF recurrence after PVI has been reported to be electrical reconnection between the left atrium and pulmonary veins, which re-establishes abnormal rhythm, said study investigator Atsushi Kobori, MD, from Kobe ...
Leadless pacemaker study assesses safety and efficacy
2015-08-30
LONDON, UK - A leadless cardiac pacemaker showed "good safety and reliable function" during the initial six months of follow-up in the LEADLESS II study, investigators reported during a Hot Line presentation at the ESC congress 2015.
The findings, published simultaneously in the New England Journal of Medicine, suggest the device is effective and safe, and can serve as an alternative to conventional transvenous pacemakers in patients with indications for permanent pacing, said principal investigator Vivek Reddy, MD.
"Leadless cardiac pacemakers have the potential to ...
Antiarrhythmia drugs no impact on late AF recurrence
2015-08-30
LONDON, UK - In patients with atrial fibrillation (AF) treated with radiofrequency catheter ablation, the addition of antiarrhythmic drugs (AADs) for 90 days after the procedure did not reduce arrhythmia recurrence rates at one year, according to results of the Efficacy of Antiarrhythmic Drugs Short-Term Use after Catheter Ablation for Atrial Fibrillation (EAST-AF) trial.
Results of the study, presented as a Hot Line at ESC Congress 2015
The study did show a temporary benefit of AAD, but the effect disappeared as soon as medication was stopped, suggesting no benefit to ...
Multiple risk factors cancel impact of atrial fibrillation on ischemic stroke risk
2015-08-30
London, UK - 30 Aug 2015: The impact of atrial fibrillation on ischaemic stroke risk in elderly patients is eliminated with multiple risk factors, according to an 11 year study in more than 425 000 patients presented at ESC Congress today.1 The findings suggest that stroke prevention in the elderly may need to focus on the concomitant effects of multiple risk factors rather than on a specific risk factor such as atrial fibrillation (AF).
"The incidence of ischaemic stroke increases with greater numbers of cardiovascular risk factors," said principal investigator Dr Yutao ...
Rapid, more sensitive test speeds up chest pain triage
2015-08-30
LONDON, England - 30 August, 2015: Patients arriving at the emergency department with chest pain suggestive of acute myocardial infarction (AMI) can be triaged more quickly and more safely using a new rapid assay with refined cut-offs, German research suggests.
The Biomarkers in Acute Cardiovascular Care (BACC) study, presented as a Hot Line at ESC Congress 2015, suggests this new algorithm can reduce mortality and cut triage times to one hour, compared to the standard three-hour approach.
"There is an urgent need for fast decision-making for this growing patient population," ...
