How healthy is your heart? Assessing your cardio-metabolic health and cardiovascular health is crucial. Cardiac arrest and stroke are the leading causes of death in the United States and other developed nations, often influenced by factors like family history of cardiovascular disease, smoking, diabetes, high cholesterol, and high blood pressure.
Being overweight also heightens the risk of heart attack and stroke, exacerbating these issues. Despite widespread awareness, few people implement consistent measures to reduce these risk factors and prevent the onset of cardiovascular diseases.
The cardiovascular system, comprising the heart, blood, and blood vessels, is essential for sustaining life. The heart, a remarkable organ, pumps 5 to 6 liters of blood per minute and beats about 100,000 times daily. It requires well-oxygenated blood and nutrients to function effectively, much like any other muscle. The circulatory system, extending over 100,000 kilometers, circulates oxygen-enriched blood throughout the body, delivering nutrients and removing metabolic byproducts like carbon dioxide.
Heart disease often starts with the buildup of cholesterol, fatty acids, and calcium in the arteries, a condition known as atherosclerosis. This can lead to reduced oxygen delivery to the heart and increased blood pressure, potentially resulting in a heart attack or severe cardiac arrhythmias.
Cardio-metabolic health encompasses several risk factors critical for assessing overall health. A study published in the Journal of the American College of Cardiology analyzed data from over 55,000 US adults, revealing only 6.8% had optimal cardio-metabolic health in 2018. This reflects a decline from 7.7% in 2000 and 8.4% in 2004, with factors like obesity, overweight, and elevated blood sugar levels contributing to this downturn.
The study also highlighted significant disparities in health, noting poorer cardio-metabolic conditions predominantly among non-white, male, economically disadvantaged, less educated, or older demographics. It also recognized the direct impact of social factors such as residence and employment on cardiovascular health.
Alarmingly, the study suggests that optimal cardio-metabolic health may be rarer post-COVID-19, as physical activity levels dropped and unhealthy habits increased during the pandemic.
Numerous studies indicate that both Americans and populations in many developed countries fall short in maintaining health. Knowing your cardiovascular health can serve as a catalyst for action and a personal call to improve. The effort to prevent a heart attack or stroke is undoubtedly worthwhile.
Consider your cardio-metabolic health as invaluable. Begin by checking your blood pressure, blood sugar, and cholesterol levels to gain insight on enhancing your cardiovascular health.
Although many of us fail to take adequate preventative measures against heart attacks, strokes, and other cardio-metabolic issues, don't lose heart! Focus on yourself, roll up your sleeves, and take proactive steps to manage your health.
Key factors negatively impacting heart and cardiovascular health include:
SMOKING
HIGH BLOOD PRESSURE
HIGH CHOLESTEROL
DIABETES
SEDENTARY LIFESTYLE
OBESITY
Many of these risk factors are lifestyle-related, with a sedentary lifestyle being a primary cause of heart disease. Hence, it's crucial to move! Even modest amounts of exercise can significantly enhance cardio-respiratory fitness and potentially extend your life.
To strengthen your cardiovascular system, regular and appropriately intense exercise is essential for heart health and offers comprehensive health benefits. While any physical activity is beneficial, its positive impact on heart health is maximized when it is consistent and prolonged over months and years.
But what is the ideal amount of exercise for optimal cardiovascular safety? A study funded by the National Institute of Health (NIH) involving over 100,000 participants (63% women and 37% men, average age 66) suggests that the optimal exercise duration ranges from 150 to 600 minutes per week. The findings, published in the American Heart Association's journal Circulation, highlight this duration as beneficial for significantly reducing the risk of premature death from cardiovascular causes.
The same study indicates that exercising two to four times the recommended level of moderate to intense activity weekly notably lowers the risk of early death due to cardiovascular reasons. However, exercising beyond 600 minutes per week does not confer additional protective benefits, according to the findings also published in Circulation.
