Heart health or cardiovascular diseases are the leading causes of mortality in the world. In 2019, 17.9 million people died due to cardiovascular diseases with 85% of these deaths attributed to heart attacks and strokes. There are many types of cardiovascular diseases, many of which are chronic diseases. While the numbers of death due to heart attacks may seem high, new study published in the Journal of the American Heart Association shows these numbers have actually decreased. However, while these numbers went down, chronic diseases have seen a rise. How Have Heart Disease Deaths Changed Over Time? To understand how heart disease deaths have changed, researchers looked at national data from 1970 to 2022, focusing on adults aged 25 and older. Heart disease covers many different heart problems. Even though heart disease remains the leading cause of death in the U.S. (responsible for 24% of all deaths in 2022), the total number of deaths from heart disease actually went down by 66%. Deaths from ischemic heart disease (the most common type, caused by blocked arteries) dropped significantly, from 91% to 53% of all heart disease deaths. Deaths from heart attacks (often the first sign of ischemic heart disease) fell by a huge 89%, making up less than a third of all heart disease deaths in 2022. But the study also found a big increase in other heart conditions, which now account for nearly half of all heart disease deaths. The three conditions that rose the most were: Hypertensive heart disease Deaths from this condition, caused by long-term high blood pressure, went up by 106%. It now makes up 13% of all heart-related deaths. Heart failure Deaths from this condition, where the heart can't pump enough blood over time, rose by 146%. It now accounts for 12% of all heart-related deaths. Arrhythmias (irregular heartbeats) Deaths from arrhythmias, where the heart beats too fast, too slow, or unevenly, soared by 450%. They now make up 4% of all heart-related deaths. One of the study's authors mentioned that while these trends are "quite clear," some changes in how deaths were categorized might have caused small inaccuracies. Also, the study didn't fully consider how other health problems or things like race might have affected the results. For example, some heart problems might have been underestimated if they stemmed from ischemic heart disease. Despite these minor points, experts agree the study provides "valuable insights" and is a "well-designed, large-scale study" using over 50 years of data. Why the Shift to Chronic Heart Conditions? Experts believe the drop in some heart disease deaths is due to better ways to diagnose problems and improved care. This includes new medicines and procedures that help restore blood flow to the heart. However, many people who survive a heart attack go on to develop other heart conditions like heart failure or arrhythmias. When you combine this with a growing older population and rising rates of obesity, diabetes, and high blood pressure, it creates "the perfect storm for chronic cardiac disease." This new "wave of chronic heart disease deaths" mainly affects older adults and those with several health issues. How to Protect Your Heart?To keep your heart healthy, focus on a few key areas: know your numbers by tracking your blood pressure, cholesterol, blood sugar, and weight, as early detection of issues is vital. Stay active with at least 150 minutes of moderate exercise weekly; even walking can significantly improve heart function. Eat a nutritious diet rich in vegetables, fruits, whole grains, lean proteins, and healthy fats, following heart-healthy guidelines. Avoid smoking or seek help to quit, as it's a primary cause of heart disease. Finally, manage stress and get enough sleep, as these often-overlooked factors are crucial for reducing your heart risk.
