Heart disease is the main cause of death worldwide. However, according to a new study, the total number of heart disease deaths has decreased in the last five decades of 66% 25 years and over. Better yet, the death of death from heart attacks decreased by almost 90%.
“Over the past 50 years, our understanding of heart disease, which causes it and how we treated it has changed dramatically,” said dr. Sarah King, a second -year resident of internal diseases in California at Stanford University Medical School.
“There were big steps in the help of people to survive the initial acute heart events that were once considered to be the death penalty,” the king’s statement said.
Unfortunately, those positive news have many sides. According to a study published on Wednesday in a study published on Wednesday, death from all other heart disease, including arrhythmia, heart failure and hypertensive heart disease, increased by 81% in the US.
It is important to look at both sets of numbers, said dr. Andrew Freeman, Denner of National Jewish Health Cardiovascular Prevention and Health.
“These days, the likelihood of a heart attack is relatively low compared to where it was, but the likelihood of a high heart attack is still high,” Freeman said, who did not participate in the study.
“You can develop heart failure – where your heart is unable to pump enough blood to meet your body needs, and you always lack breathing,” he said. “Or maybe you are taking a lot of blood pressure, fluid retention and cholesterol, or you never feel best.
“One thing is alive, another is to be alive and well.”
The risk of cardiovascular growth
The study analyzed government data on death from heart disease in 1970-2022. Heart attacks were responsible for 54% of all heart problems. By 2022 This number decreased to 29%.
The deaths of atrial fibrillation and other arrhythmias occurring when electrical impulses in the heart make mistakes and cause irregular heart beat or “rupture” in the chest, in the 1970s were rare. By 2022 The number increased to 450% – about 4% of all deaths from heart disease, and the study found.
Heart failure deaths increased 146% over the same period, and death due to persistent high blood pressure increased by 106%.
Changes in cardiovascular risk factors contribute to the increase in certain heart disease, the study said. Obesity, type 2 diabetes, high blood pressure, poor food selection and physical inactivity have increased over the last 50 years. The prevalence of obesity increased from 15% in 1970. Up to 40% of 2022, found that. Type 2 diabetes and prediabetes now affect almost half of all adults in the US. High blood pressure increased from 30% in 1978. Up to nearly 50% 2022
Another potential co -author is the aging population of baby boomers, now having reached the time when they usually develop heart disease.
“All of these risk factors contribute to the constant burden of heart disease, especially with heart failure, hypertension heart disease and arrhythmias,” said senior study author dr. Latha Palaniappan, Cardiovascular Medicine Professor and Associated Deets for Research on Medical Research.
“Heart disease did not disappear,” Palaniappan said in a statement. “Now the focus must be on people with strong, healthy hearts with aging, preventing events, and prevention can begin in childhood.”
