Introduction

What is cardiovascular well-being - overview

Cardiovascular well-being refers to the overall health and optimal functioning of the cardiovascular system, which includes the heart, blood vessels, and blood. It encompasses various aspects such as maintaining healthy blood pressure, cholesterol levels, and heart function, as well as preventing or managing cardiovascular diseases and conditions. At the beginning of the 20th century, CVD was responsible for less than 10 per cent of all deaths worldwide, but by 2001 that figure was 30 per cent. About 80 per cent of the global burden of CVD death occurs in low- and middle-income countries. Murray and Lopez (1996)predicted that CVD will be the leading cause of death and disability worldwide by 2020 mainly because it will increase in low- and middle-income countries.¹

Importance of cardiovascular health

Data obtained in 2013 revealed that cardiovascular disease (CVD) stands as the primary global cause of mortality in Western nations, constituting 17.3 million deaths annually worldwide (equivalent to 31.5% of all global deaths), albeit exhibiting a steady decline over the past decade. In the United States, one out of every three deaths, and in Europe, one out of every four deaths, can be attributed to CVD  projections indicate that by 2035, over 130 million adults in the United States alone, amounting to 45.1% of the population, are anticipated to exhibit clinical manifestations of CVD.

CVD encompasses a spectrum of conditions affecting the heart and blood vessels, including hypertension, stroke, atherosclerosis, peripheral artery disease, and venous disorders. The likelihood of developing CVD correlates with unhealthy dietary habits such as excessive sodium and processed food consumption, added sugars, and unhealthy fats coupled with insufficient intake of fruits, vegetables, whole grains, fibre, legumes, fish, and nuts, alongside inadequate physical activity, obesity, stress, alcohol consumption, or tobacco use.²

Overview of the cardiovascular system

 The conventional understanding of cardiac dynamics has long been associated with the morphological structure of the left ventricle, right ventricle, and septum, diverging from the heart's anatomical description dating back five centuries, which depicted a helical and circumferential wrap architectural configuration. The helical ventricular myocardial band (HVMB) proposed by Torrent Guasp elucidates this anatomy and its structural characteristics, providing insights into the underlying mechanisms behind the heart's six dynamic actions: narrowing, shortening, lengthening, widening, twisting, and uncoiling.

These structural revelations prompt inquiries into established principles governing "accepted cardiac mechanics," challenging and potentially overturning them. These principles encompass descriptions of the left ventricle, right ventricle, and septum, the timing of mitral valve opening, the isovolumic relaxation period, the mechanisms underlying torsion and twisting, the phenomenon of untwisting, the causes of longitudinal and circumferential strain, echocardiographic sub-segmentation, resynchronization techniques, dynamics of right ventricular function, the etiology of diastolic dysfunction, and unrecognized impairments of the septum.³

Factors affecting cardiovascular wellbeing

• Lifestyle factor (Exercise, Smoking, Alcoh consumption)
• Environmental factors and genetic factor

Significant evidence has demonstrated the importance of high levels of physical activity, exercise training (ET), and overall cardiorespiratory fitness in preventing and managing cardiovascular diseases. This article explores fundamental aspects of exercise physiology, the immediate and long-term responses to ET, and the impact of physical activity and cardiorespiratory fitness on cardiovascular conditions.⁴

Benefits of exercise training in cardiovascular well-being

Numerous observational studies and randomized controlled trials have demonstrated the advantages of physical activity (PA) and exercise training (ET) in individuals with cardiovascular disease (CVD), including coronary heart disease (CHD) and heart failure (HF) . Perhaps the most compelling evidence of ET benefits is observed in structured cardiac rehabilitation and exercise training (CRET) programs for patients following significant CHD events.⁵

Strategies for improving cardiovascular wellbeing

One effective strategy to mitigate the burden of cardiovascular disease (CVD) is to promote optimal cardiovascular health, a recommendation endorsed by the American Heart Association (AHA) for CVD prevention. Optimal cardiovascular health is characterized by adherence to seven health-promoting behaviours known as Life’s Simple.

These include managing blood pressure, controlling cholesterol levels, reducing blood glucose, engaging in regular physical activity, maintaining a healthy diet, achieving weight loss, and quitting tobacco use.

Tobacco control can be achieved by encouraging a non-smoking and tobacco-free lifestyle. Educating patients about the dangers of tobacco use and the risks associated with second-hand smoke exposure is a crucial aspect of health promotion.⁷

To create a compelling argument on the importance of prioritizing cardiovascular well-being based on scientific research, I'll summarize and reference findings from reputable studies and reviews.

Importance of prioritizing cardiovascular wellbeing

Cardiovascular well-being is paramount for ensuring overall health and longevity, as cardiovascular diseases (CVD) remain the leading cause of death globally. According to a study published in *The Lancet*, CVD accounted for approximately 17.9 million deaths in 2019, representing 32% of all global deaths.⁸ Prioritizing heart health can significantly reduce these numbers, offering profound public health benefits.

Reduction in disease risk and mortality

• Numerous studies have shown that lifestyle interventions targeting cardiovascular health can dramatically decrease the risk of CVD. The American Heart Association (AHA) emphasizes that adhering to ideal cardiovascular health metrics, such as those outlined in "Life's Simple 7," can lead to a significant reduction in CVD incidence and mortality⁹
• A review in *Circulation* highlighted that individuals maintaining optimal levels of physical activity, a balanced diet, and non-smoking status had a lower risk of heart disease and stroke¹⁰

**Improvement in overall health**

• Cardiovascular health is closely linked to overall physical and mental health. Research published in the *Journal of the American College of Cardiology* found that improved cardiovascular health correlates with reduced risks of other chronic diseases, including diabetes and certain cancers¹¹
• Another study in *JAMA* noted that individuals with better cardiovascular health metrics reported higher levels of physical fitness and better mental health outcomes, such as reduced depression and anxiety¹²

**Enhanced quality of life**

• Prioritizing cardiovascular well-being not only extends life expectancy but also improves the quality of life. According to a study in *Heart*, individuals who engage in regular physical activity and maintain a healthy diet experience improved mobility, cognitive function, and emotional well-being¹³
• Furthermore, prevention of CVD through healthy lifestyle choices reduces the need for medical interventions, which can be invasive and costly, thereby preserving an individual's independence and daily functioning¹⁴

Economic and societal benefits

• The economic burden of CVD is substantial. A study in *Health Affairs* estimated that the direct medical costs associated with CVD will reach over $1 trillion annually by 2035 in the United States alone.¹⁵ By prioritizing cardiovascular health, these costs can be significantly reduced
• Improved cardiovascular health contributes to a more productive society. Healthy individuals are less likely to miss work due to illness and are more capable of performing their jobs effectively, thereby enhancing overall economic productivity¹⁶

Summary

In summary, the importance of prioritizing cardiovascular well-being is underscored by its profound impact on reducing disease risk and mortality, improving overall health, enhancing quality of life, and yielding economic benefits. By adhering to established guidelines for heart health, individuals and societies can achieve significant health improvements and cost savings, making cardiovascular well-being a critical public health priority.
