How air pollution can affect your heartbeat



for 1.4 billion people in China, the simple act of breathing has long been a risk. Live in ninth dirtiest country in the world In terms of air quality, Chinese people lose an average of 2.6 years of life per capita due to air pollution alone. the biggest risk certainly pulmonary, while air pollution leads to shortness of breath, wheezing, coughing, asthma attacks and chest pain. But pollution also affects the heart; United States Environmental Protection Agency reports that Exposure to fine particles, as well as nitrogen oxides alone, can lead to premature aging of blood vessels, as well as to the rapid accumulation of calcium in the coronary artery.

Now, new research V Journal of the Canadian Medical Association strongly links air pollution associated with burning fossil fuels, especially coal, to another risk to the heart: arrhythmias, or irregular heartbeats. The study not only showed that exposure to air pollution leads to arrhythmias, but also leads to them quickly when the heart responds in real time to changes in air quality in a given location. It’s bad news like arrhythmias can lead to blood clots, stroke, heart failure, and even sudden death in some cases.

“We found that acute exposure to outdoor air pollution was associated with an increased risk of symptomatic arrhythmia,” the doctor said. Renji Chen of Fudan University in Shanghai, one of the 20 co-authors of the paper, in a statement. “Risks occurred within the first few hours after exposure and could persist for up to 24 hours.”

Changing the emission profile in China is long overdue. V country emissions 27% of all global carbon dioxide production and 30% of all greenhouse gases. Beijing’s much-touted green transition aims to see the country peak in carbon emissions by 2030 and then decline to carbon neutrality by 2060. Even as a country leading the world in solar and wind power generation, China still allows the construction of six times more coal-fired power plants than the rest of the planet combined, giving the green light to an average of two plants per week in 2022. China is certainly not alone in sticking to fossil fuels — and all the risks that come with it. USA second largest emitter in the world greenhouse alleys, and so far there is not a single nation that has become completely green. All this is fraught with health problems anywhere, but it is in China, with its huge population and particularly dirty skies, that the problem is most acute.

Chen and colleagues collected data from 2,025 hospitals in 322 cities in China between 2015 and 2021 and covered 190,115 patients presenting to emergency departments with complaints of arrhythmias. The researchers compared these reports with records from air quality monitoring stations located within 50 km (31 miles) of each hospital on the day each patient was admitted. The average distance for each monitoring station was actually much less, only 4.4 km (2.7 miles) from each hospital.

The researchers studied four different types of arrhythmia:

In terms of pollutants, the study focused on accounting for the six most common and dangerous ones monitored by air quality monitoring stations:

  • nitrogen dioxide
  • sulfur dioxide
  • carbon monoxide
  • ozone
  • large particles (size from 2.5 to 10 micrometers or millionths of a meter)
  • small particles (less than 2.5 microns).

In the entire sample group of 190,115 people, atrial fibrillation was the most common arrhythmia, affecting 50.6% of people included in the study; the next was supraventricular tachycardia – 24.8%; followed by extrasystoles at 21.9% and atrial flutter at 2.8%. Not all conditions have been affected equally by pollutants. Atrial flutter and supraventricular tachycardia appear to be most closely associated with dirty atmospheric conditions; The former rose by about 18% on especially dirty days, while the latter jumped by about 13%.

Of the six pollutants, nitrogen dioxide was the most damaging, increasing the likelihood of all four types of arrhythmia. Cases of atrial flutter increased by 11.4% on days when nitrogen dioxide levels were high; for ventricular tachycardia it was 8.9%, followed by extrasystoles at 3.7% and atrial fibrillation at 3.4%.

As you might expect, geography and time of year played a role in who developed arrhythmia as a result of exposure to polluted air. The greatest incidence was in the heavily industrialized south; dirty air was most common in autumn and winter, when more coal was burned for heating.

As for the exact mechanism that causes the six pollutants to cause the arrhythmia, the researchers admit they are unsure. Among the possibilities they list are some influence on the electrical activity of the heart; systemic inflammation; and a general disruption of the autonomic nervous system, which regulates not only heart rate, but also blood pressure, respiration, digestion, and more.

“Although the mechanisms are not fully understood,” the researchers write, “the link between air pollution and the acute onset of arrhythmias we observe is biologically plausible. Our results… highlight the need for more stringent air pollution controls as well as rapid responses for vulnerable populations during air pollution episodes.” This is good advice for China, as well as for the rest of the world that uses fossil fuels.

Two hospitals are under federal investigation into the care of a pregnant woman who refused an abortion.




The Centers for Medicare and Medicaid Services are investigating two hospitals that “failed to provide essential stabilizing care to a person experiencing a medical emergency in violation of the Emergency Medical Services and Labor Act (EMTALA)”, according to letter from US Secretary of Health and Human Services Xavier Becerra.

Under the EMTALA, healthcare professionals are required to “offer treatment, including abortion, that the provider reasonably determines is necessary to stabilize the patient’s emergency medical condition,” Becerra said Monday in a letter to the national associations of hospitals and healthcare providers.

V National Women’s Law Centerwhose statement says it filed the original EMTALA complaint on behalf of Milissa Farmer, identified the hospitals as Freeman Hospital West of Joplin, Missouri, and the University of Kansas Health System in Kansas City, Kansas.

The patient was 18 weeks pregnant when her membranes ruptured prematurely, writes Becerra, but was told her pregnancy was not viable.

“While her doctors told her that her condition could deteriorate rapidly, they also told her that they were unable to provide her with care that would prevent infection, bleeding, and possibly death because, they said, hospital policy forbade treatment that could be considered an abortion,” wrote Becerra.

Becerra added in a statement on Monday: “Fortunately, this patient survived. But she never had to go through the horrific ordeals she experienced in the first place. We want her and every patient like her to know that we will do everything we can to protect their lives and health, and to investigate and enforce the law to the fullest extent of our legal powers.”

Abortion is illegal in Missouri, with some exceptions, such as to save the mother’s life. State law requires a consultation and a 72-hour waiting period. In Kansas, abortion is generally prohibited at 22 weeks’ gestation or later, with a 24-hour waiting period and mandatory consultation.

Passed in 1986, the EMTALA requires hospitals to provide stabilizing treatment to patients with acute illnesses or transfer them to facilities where such care will be provided, regardless of any conflicting state laws or regulations.

Changes in state laws following the U.S. Supreme Court’s decision to end the right to abortion have left many hospitals and health care providers unsure of what steps they can legally take in such cases. HHS published guide confirmed last year that EMTALA requires providers to offer stabilizing care for emergencies that may include abortion.

Hospitals found to be in violation of EMTALA may lose their agreements with Medicare and Medicaid providers and face administrative sanctions. An individual doctor may also face civil sanctions if they are found to be violating the rules.

HHS can impose a fine of $119,942 per violation for hospitals with more than 100 beds and $59,973 for hospitals with fewer than 100 beds. A doctor can be fined $119,942 for a violation.

The National Women’s Law Center says the new actions are the first since Roe v. Wade was upended that EMTALA was used against a hospital that refused an emergency abortion.

“Patient care has been reviewed by the hospital and found to be consistent with hospital policy,” the University of Kansas Health System said in a statement to CNN. “It met the standard of medical care based on the facts known at the time and complied with all applicable laws. CMS has a procedure for dealing with this complaint and we respect that procedure. The University of Kansas Health System follows federal and Kansas laws in providing appropriate, stabilizing, and quality care for all of its patients, including obstetric patients.”

Freeman Hospital did not immediately respond to CNN’s request for comment.

An HHS spokesman told CNN that both hospitals are working to comply with the law.

In a legal center statement, Farmer said she was pleased with the investigation, “but pregnant women across the country continue to be denied medical care and face an increased risk of complications or death, and this must stop. I’ve dealt with an unimaginable loss before, and the hospitals have made things difficult. I’m still emotionally struggling with what happened to me, but I’m determined to keep fighting because no one else has to go through this.”

Rihanna finally arrived at the Met Gala in a literal cloud



If the Met Gala is held in New York and Rihanna doesn’t show up, will it even happen? Thank God we didn’t have to search for the answer to this question, because the queen is here! What is she So late, but she’s here!

On Monday, May 1, Rihanna climbed the iconic steps at the Metropolitan Museum of Art in a look that will be hard to beat next year – even for RiRi. The mom-to-be, who opened up about her second pregnancy during an appearance on the Super Bowl halftime show earlier this year, arrived in what is essentially a white cocoon of rosettes. The Valentino look, which featured an ivory skirt with a train that required multiple styling, covered the singer from head to toe in bridal white, probably a Chanel tribute to Karl Lagerfeld’s fiancée.

Evening dress code “in honor of Carl” has received many interpretations, but let Rihanna come in something completely unique.
