Cancer is now the leading cause of death in rich countries, killing twice as many people as heart disease, which remains the leading cause of death among middle-aged adults worldwide, reports Reuters. A new study reveals that this "epidemiological transition" is at stake in the "rich world" countries, including Sweden, Canada, Chile, Argentina, Poland and Turkey; Researchers believe this may be due to improvements in the prevention and treatment of heart disease in these countries, reports CNN. "While cardiovascular disease is decreasing in many countries, cancer mortality will likely become the leading cause of death in the future" in the world, said the study's lead author, according to Fox News.
Overall, cardiovascular diseases (a group of diseases including heart failure, angina, heart attack and stroke) kill 40% of adults aged 35 to 70 worldwide, with cancer ranking second at 26%. But in high-income countries, the prevalence of cholesterol-lowering statins and medications for high blood pressure has resulted in a significant decline in rates of cardiovascular disease. In middle-income and low-income countries, researchers found that the use of drugs to treat heart disease was much lower. Among the limitations of the study, however, is the fact that it did not examine all the countries of the world. The United States was not included, but a study last year found that even though heart disease was more likely to kill low-income counties in the United States, cancer was more likely to kill those in counties. high income.
