Background on Cardiovascular Disease
Cardiovascular disease is not a single ailment but a group of disorders affecting the heart and blood vessels. It is the leading cause of death globally, accounting for millions of fatalities each year. The spectrum of cardiovascular conditions includes:
- Coronary artery disease (CAD): Often characterized by the narrowing or blockage of the coronary arteries, CAD is the most common type of heart disease and can lead to heart attacks.
- Stroke: Occurs when the blood supply to part of the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients.
- Heart failure: A chronic condition where the heart is unable to pump blood efficiently, leading to fatigue and shortness of breath.
- Arrhythmias: Abnormal heart rhythms that can range from harmless to life-threatening.
The prevalence of cardiovascular disease is influenced by several factors, including genetics, lifestyle choices, and environmental conditions. Sedentary habits, unhealthy diets, smoking, and high stress levels are among the primary risk factors that contribute to its development. As societies become more industrialized, these risk factors have become increasingly common, leading to a surge in CVD cases.
Traditional surveillance methods for cardiovascular disease include hospital records, mortality databases, and community health surveys. While these methods provide detailed clinical data, they often lag behind real-time events. Additionally, they may not fully capture the public’s perception or concern about these diseases until after significant changes in incidence or mortality occur. This gap highlights the need for supplementary tools that can offer more immediate insights into population health trends.
