While the term "killer disease" can be used informally to describe many serious illnesses, ischaemic heart disease is currently the world's biggest killer. This is supported by recent data indicating it accounts for a significant portion of global deaths.
Understanding Ischaemic Heart Disease
Ischaemic heart disease, also often referred to as coronary artery disease, occurs when the arteries that supply blood to the heart become narrowed or blocked, usually due to a buildup of plaque. This can lead to a heart attack or other serious complications.
Key Points About Ischaemic Heart Disease:
- Global Impact: It's the leading cause of death globally.
- Mortality Rate: In 2021, it caused 9.1 million deaths, which is a 2.7 million increase since 2000.
- Causes: Typically results from atherosclerosis, where fatty deposits accumulate in arteries.
- Consequences: Can lead to chest pain (angina), heart attacks, and heart failure.
Why Ischaemic Heart Disease is Considered a Major "Killer Disease"
The term "killer disease" is often used to describe conditions that cause a high number of deaths. Ischaemic heart disease fits this description due to its widespread prevalence and fatal consequences if left unmanaged.
Prevention and Management:
While ischaemic heart disease is serious, it's not insurmountable. Lifestyle adjustments can significantly reduce risk, including:
- Regular physical activity.
- A healthy diet, low in saturated fats.
- Smoking cessation.
- Managing blood pressure and cholesterol.
- Regular checkups.
Conclusion
Although many diseases pose a serious threat to health, based on the reference provided, ischaemic heart disease can be considered the leading "killer disease" due to its high global mortality rate and overall impact on human health.
