Coronary artery disease (CAD) is a global health issue that quietly affects millions. Often without symptoms until severe complications arise, CAD restricts blood flow to the heart, leading to heart attacks and other potentially life-threatening events. Understanding its risk factors, detection methods, and treatment options is essential in combating this “silent killer.” The Basics of Coronary Artery Disease CAD is caused by the build-up of plaque in the coronary arteries, which supply blood and oxygen to the heart. This plaque, composed of fat, cholesterol, calcium, and other substances, hardens, and narrows the arteries over time. Reduced blood flow deprives the heart of oxygen, causing symptoms such as chest pain (angina) and, in severe cases, heart attacks. This gradual development makes CAD challenging to detect early, underscoring the importance of regular health screenings for at-risk individuals. Advances in Early Detection: Coronary Calcium Scoring One of the most

Invisible illnesses, or undiagnosed diseases, affect millions globally, presenting significant challenges not only to those who suffer from them but also to healthcare systems. These conditions, which often manifest without visible symptoms, can lead to prolonged suffering due to delays in diagnosis and appropriate treatment. This article explores the nature of invisible illnesses and highlights the crucial aspects of managing their impact. The Complexity of Invisible Illnesses Invisible illnesses encompass a wide range of conditions including chronic fatigue syndrome, fibromyalgia, mental illnesses, and more complex genetic and neurological disorders. These diseases are termed "invisible" because they do not exhibit outward signs that are easily recognizable, even though they can severely impair an individual's quality of life. Diagnostic Challenges One of the primary issues with invisible illnesses is the difficulty in obtaining a diagnosis. Traditional diagnost
