Cardiovascular Diseases: The World’s Leading Cause of Death, What You Must Know


Did you know that cardiovascular diseases are the leading cause of death worldwide, claiming approximately 20 million lives each year? These diseases surpass cancer in mortality rates, making them a critical issue that demands our attention.


In this article, we’ll explore the severity of cardiovascular diseases, the importance of prevention, and the vital role of early diagnosis in combating these conditions.




How Serious Are Cardiovascular Diseases?

Cardiovascular diseases (CVDs) encompass a wide range of conditions affecting the heart and blood vessels. Major heart diseases include myocardial infarction, hypertension, heart failure, arrhythmia, cardiomyopathy, and ischemic heart disease. Vascular diseases such as stroke and peripheral vascular disease are also part of this category.



A Global Health Crisis

Cardiovascular diseases are currently the leading cause of death worldwide. In 2021 alone, approximately 20.5 million people lost their lives to CVDs—a significant rise from 12.1 million deaths in 1990. These diseases account for about 33% of all deaths globally, highlighting their status as not just an individual health issue but a pressing public health threat.


South Korea Is No Exception

In South Korea, heart diseases—one of the main subsets of cardiovascular diseases—rank as the second leading cause of death, following cancer. As of 2023, the mortality rate from heart diseases stood at 64.8 per 100,000 people, accounting for approximately 9.4% of total deaths in the country.


The Economic Burden Cannot Be Ignored

Cardiovascular diseases have a profound economic impact in addition to their health consequences. In the United States, for example, CVDs accounted for about 12% of total healthcare expenditures between 2018 and 2019. Even more concerning is the projection that the annual cost associated with CVDs will exceed $1 trillion by 2035. This underscores the critical need for early diagnosis and management.




Causes and Prevention of Heart Diseases

Key risk factors for heart diseases include hypertension, high cholesterol, smoking, obesity, diabetes, and physical inactivity. Among these, hypertension is recognized as the leading cause of CVDs. The good news is that heart diseases are largely preventable. Through healthy lifestyle habits and regular health checkups, these risk factors can be effectively managed early on.



Early Diagnosis of Heart Diseases: The Role of Cardiac MRI

Heart diseases can be prevented and treated effectively through early diagnosis and intervention. In this regard, cardiac MRI has emerged as a groundbreaking and essential diagnostic tool.

Cardiac MRI provides high-resolution images that allow for a detailed evaluation of the heart’s structure and function. It can detect subtle abnormalities that may be missed by X-rays or CT scans. For example, cardiac MRI is indispensable in identifying life-threatening conditions such as myocardial infarction, hypertrophic cardiomyopathy, cardiac tumors, and congenital heart diseases at their earliest stages.

What makes cardiac MRI even more remarkable is its non-invasive nature and the absence of radiation exposure, ensuring both safety and accuracy. By enabling early diagnosis, cardiac MRI can significantly reduce mortality rates from heart diseases and greatly enhance patients' quality of life. This makes it a vital advancement in modern medical technology.



Heart Diseases Are Preventable

Heart diseases remain one of the most critical health challenges globally. However, with early diagnosis and proactive management, they are largely preventable. Leveraging cutting-edge medical technologies like cardiac MRI can save more lives and help individuals lead healthier lives.
