Study: Health crisis deaths fall as heart failure increases
NEWYou can now listen to Fox News articles!
The deaths of heart attacks have dropped in recent years – but other types of cardiovascular disease still represent a major threat.
A new study by the American Heart Association (AHA) revealed that overall mortality rates linked to heart disease has decreased by 66% and that deaths of heart attacks dropped by almost 90%.
Although heart attacks are no longer the most fatal form of heart disease, there have been increases in other types – heart failure, arrhythmias (irregular cardiac rhythms) and hypertensive heart disease (long -term high blood pressure).

The results were published in the Reading Committee newspaper of the American Heart Association.
In the study, researchers have analyzed more than 50 years of data from US Centers for Disease Control and Prevention (CDC), focusing on cardiac disease in adults aged 25 and over.

In 1970, heart attacks – also known as ischemic heart disease – represented more than half (54%) of all deaths of heart disease, the study revealed.
In 2022, only 29% of deaths by heart disease were caused by heart attacks.
However, other types of heart deaths – such as heart failure, hypertensive heart disease and arrhythmia – have however increased during this period.

In 2022, these other types were responsible for 47% of deaths by heart disease, compared to only 9% in 1970, revealed the study.
“This change in distribution in the types of heart disease that died the most was very interesting for us,” said the first author of the study, Sara King, MD, a second -year internal medicine residing in the Stanford School of Medicine Department in Stanford, California, in the press release.

“This evolution in the past 50 years reflects incredible successes in the way heart attacks and other types of ischemic heart disease is managed,” she continued.
“However, the substantial increase in deaths by other types of heart disease, including heart failure and arrhythmia, poses emerging challenges that the medical community must take up.”
“The increase in other types of cardiac diseases leading to death compensated for the death of the death of heart attacks.”
Arrymia, or irregular cardiac rhythms, occur when electrical impulses at the heart are too fast, slow or erratic, according to AHA. A current example of arrhythmia is atrial fibrillation (AFIB), which begins in the upper bedrooms of the heart.
Heart insufficiency is defined as a “chronic condition where the heart is unable to pump enough blood to meet the needs of the body of the body and oxygen”.

Hypertensive heart disease describes damage to the heart caused by long -term and untreated blood pressure, AHA said.
Sadiya S. Khan, MD, cardiologist and associate professor at the Northwestern University in Chicago, was not involved in the study but commented “important analysis”.
“Fortunately, this study suggests significant progress in a avoidable cause of death-heart attacks,” she told Fox News Digital.

“Unfortunately, this suggests that there is a smoking crisis of other types of death of heart disease which can be partly linked to heart attacks, but which speak of the growing burden of obesity which leads to greater heart failure and deaths linked to arrhythmia.”
“The increase in other types of cardiac diseases leading to death compensated for the death of the death of heart attacks.”
Why the decrease in heart attacks?
Researchers have presented several possible reasons for the decrease in deaths of heart attacks, mainly progress in the treatment of sudden and acute heart events.
“From the establishment and increased use of RCR passers -by and automated external defibrillators (AED) to treat cardiac arrest outside the hospital environment, for the creation of care systems that promote early recognition and rapid procedural and medical intervention to treat heart attacks, there have been large stridal to help people survive the first cardiac events Acute that was considered a death sentence, “King said in the statement.
“The next border of heart health should focus on prevention of heart attacks, and also to help people age with healthier hearts and to avoid chronic cardiac affections later in life.” (istock)
Researchers have also praised several other medical progress, including coronary dental transplant, heart imagery and many new drugs for heart disease.
Healthy lifestyle changes, such as quitting smoking, doing exercise regularly and cholesterol management and blood pressure have also contributed to the reduction of cardiac crisis deaths, the AHA report said.
Khan added: “It is important to note that this does not mean that the heart attack may not have been the driver, if a person with a heart attack has developed heart failure and it is now called a heart death.”
Risk factors remain
Despite the improvements, researchers have warned that several other risk factors for heart disease – including obesity, type 2 diabetes, hypertension and physical inactivity – always feed cases.
Obesity in particular increased from 15% to 40% during the study period, and type 2 diabetes affects almost half of American adults, according to the report.
Increased life expectancy is another factor – as people live longer, a larger aging population is more likely to feel various types of heart disease.

“We have won major battles against heart attacks; however, the war on heart disease is not over,” said King. “We must now fight heart failure and other chronic conditions that affect people as they age.”

The eight lifestyle behaviors for optimal heart health are listed below.
- Eat better
- Be more active
- Leave tobacco
- Sleep in good
- Manage weight
- Check cholesterol
- Manage blood sugar
- Manage blood pressure
Potential limitations
The researchers underlined several limits of their study, in particular that they did not analyze data by age, sex, race, ethnicity, region or urbanization.
There could also be potential inconsistencies and a “bad COD” of data over the years, they have noted.
“We have won major battles against heart attacks; however, the war on heart disease is not over.”
It is also possible that the “real burden” of heart attacks is “underestimated” in the results, according to the researchers.
“Certain conditions such as heart failure, cardiomyopathy and arrhythmias – and, in particular, ventricular arrhythmias and cardiac arrest – can be too simplistic,” they wrote. “Many of these cases probably have underlying causes which cannot be precisely differentiated using current or past CIM codes (international classification of diseases).”

Khan stressed that despite the decrease in direct deaths on the heart attack, heart disease is still the main cause of mortality in the United States, representing more than 900,000 deaths in 2022.
