MYOCARDIAL INFARCTION (STEMI)
In the case where a clot completely obstructs a coronary artery, the underlying cardiac muscle suffers and it is painful. It is a “heart attack”. This is a medical emergency!
The majority of chest pains often remain without identifiable causes. We must make sure that the heart is not the source of this pain. If you have thoracic discomfort, and it worries you, speak to a doctor.
THE INVENTION OF THE PACEMAKER (CARIOSTIMULATOR)
During the era where developments in cardiac surgeries in children with congenital abnormalities, such as a hole between the two ventricles, sudden death by blockage in electrical conduction in the heart is one of the causes of catastrophic deaths.
Coronary angiography is an examination that allows the professional to visualize the arteries of the heart known as the coronaries. As a result, it is possible to demonstrate the presence of obstructions like the presence of atheromatous plaques in these arteries.
