Fatal heart rhythm disorder related to air pollution: Study

Brussels: According to recent research presented at the European Society of Cardiology’s annual congress, arrhythmias are life-threatening and occur often on days with severely polluted air (ESC). The study was carried out on patients who had an implantable cardioverter-defibrillator (ICD), allowing the researchers to track the occurrence of arrhythmias and the delivery of life-saving therapy.
“Our study suggests that people at high risk of ventricular arrhythmias, such as those with an ICD, should check daily pollution levels,” said study author Dr Alessia Zanni, now working at Maggiore Hospital, Bologna and previously at Piacenza Hospital, Italy.
She further said, “When particular matter (PM) 2.5 and PM 10 concentrations are high (above 35 mg/m3 and 50 mg/m3, respectively), it would be sensible to stay indoors as much as possible and wear an N95 mask outside, particularly in areas of heavy traffic. An air purifier can be used at home.”

Abstract
Objective
Acute myocardial infarction (AMI) is one of the leading causes of death; however, updated data regarding clinical presentation and current management are missing in Greece. This study aimed to prospectively record the demographic and clinical characteristics of a representative sample of patients suffering from AMI, their management, and short-term outcomes.

Methods
ILIAKTIS is a national, prospective, multicenter, noninterventional study conducted under the auspices of Hellenic Society of Cardiology (HCS) and the European Initiative Stent – Save a Life. From 1st April 2020 to 30th June 2020, consecutive adult patients with STEMI or NSTEMI were enrolled in the 50 participating hospitals, appropriately selected to match the geographical and population distribution in the Greek territory.

Results
In total, 1862 patients (mean age: 64.2 ± 13.2 yrs.; 77.2% males) with AMI were enrolled. More patients presented with NSTEMI (56.8%) than with STEMI (43.2%). Primary PCI (pPCI) was the preferable treatment option for STEMI patients in PCI-hospitals (76.9% vs. 39.9% for non-PCI, p < .001) and thrombolysis in non-PCI-hospitals (47.3% vs. 17.9% for PCI-hospitals, p < .001). The mean length of hospital stay was 5.6 days. In-hospital mortality was less likely in NSTEMI compared to that in STEMI patients (aOR = 0.30; 95% CI 0.18 to 0.49). Patients initially admitted in non-PCI-hospitals showed increased risk for in-hospital (aOR = 2.29; 95% CI 1.20 to 4.42) and 30-day mortality (aOR = 1.88; 95% CI 1.20 to 2.96).

Conclusion
This study shows that the proportion of STEMI and NSTEMI patients managed interventionally has significantly increased, resulting in better clinical outcomes compared to previous Greek surveys.
