Scientists have noted a new cause of heart attacks

Scientists from Yale University, the Helmholtz Center and the University Hospital Augsburg have found that ultrafine particles (100 nanometers) found in polluted air, the main source of which in the city are automobile exhausts, can trigger a heart attack. The researchers concluded that during the first few hours of exposure to the body, particles that easily penetrate the blood can cause big heart problems.
“The work confirms what we have been guessing for a long time: the smallest particles of polluted air can affect the development of a serious heart disease. This is especially true during the first few hours,” said Kai Chen, associate professor at Yale University.He emphasized that elevated levels of ultrafine particles are a public health concern.
The study covered nearly six thousand people.
