Modern cardiology is busy performing a widespread victory over the heart attack. This is demonstrated by new data from the US, where the dying percentage has fallen by 90 percent within 50 years due to acute coronary disease. For this, arrhythmias and heart failure are becoming increasingly important, said the American cardiologist company AHA.
Experts from the National US Centers for Disease Control (CDC) investigated the cardiovascular mortality in adults in the US from the age of 25 for the period from 1970 to 2022. The results are impressive: the age adapted by age has fallen by 66 percent in the last 50 years.
In this 52 -year period, heart conditions was responsible for almost a third of all deaths (31 percent). However, the death rate due to heart conditions fell considerably: from 41 percent of all deaths in 1970 to 24 percent of all deaths in 2022.
Heart attack treatment has caused a revolution
Especially with acute heart attack, the situation has changed fundamentally. Fast recognition of the disease, immediately transport from the patient to a cardiological department, resolution of the blood clot (thrombolysis) that took place in a coronary barrel through medication and the latest catheter interventions with implantable vascular supports (stents) the change.
In addition, there were considerably improved prevention and post-treatment options, including medication to prevent blood clots formation, to control the heart rhythm, strong cholesterol reduction and to block heart muscle renovations after an infarction.
Spectacular change in mortality of heart attack
In 1970, more than half of all people died of heart conditions (54 percent), a heart attack. This outdated death rate decreased by 89 percent by 2022, because less than a third of all deaths were caused by heart attacks (29 percent) by a heart attack.
New challenges are emerging
However, the spectrum of the disease has shifted. In contrast to the heart attack, the age -related mortality rate increased by 81 percent in all other types of heart conditions (including heart failure, high blood pressure -related diseases and heart rhythm saws). This corresponds to nine percent of all deaths due to heart disease in the United States in 1970, but already 47 percent in 2022.
Rhythmias as a growing problem
Death through heart rhythm disorders, the greatest relative increase registered; The adapted death rate of age increased by 450 percent. Nevertheless, Hartartmies earned only about four percent of all deaths through heart disease in 2022.
“This development of the past 50 years reflects an incredible success in the treatment of heart attacks and other ischemic heart diseases. However, the significant increase in deaths through other heart conditions, including heart failure and heart articles, presents the medical community with new challenges,” said Sara King, the first author of the CDC study.
The study was published in the Journal of the American Heart Association (AHA), one of the three most important specialist societies in the field of cardiology.
