Abstract

  

Introduction

Coronary Artery Disease (CAD) is one of the leading causes of death worldwide, affecting millions of people and imposing a significant burden on healthcare systems. This condition arises when the coronary arteries, which supply blood to the heart muscle, become narrowed or blocked, leading to a reduction in blood flow. Over time, this can result in angina (chest pain), heart attacks, heart failure, and even sudden death. Understanding CAD is crucial, not only for those at risk but also for healthcare professionals and the general public, as awareness and early intervention can greatly improve outcomes.The heart, a powerful muscular organ, requires a constant supply of oxygen and nutrients to function effectively. This supply is delivered through the coronary arteries, which branch off from the aorta, the body's main artery. There are two main coronary arteries: the left and the right. The left coronary artery further divides into the left anterior descending artery (LAD) and the circumflex artery, while the right coronary artery (RCA) supplies blood to the right side of the heart and parts of the left side. Each of these arteries plays a critical role in ensuring that the heart muscle (myocardium) receives adequate blood flow.[1,2].

CAD typically develops over many years, starting with the accumulation of fatty deposits (plaque) on the inner walls of the coronary arteries. This process, known as atherosclerosis, begins when the endothelium (the inner lining of the artery) becomes damaged due to factors such as high cholesterol, hypertension, smoking, diabetes, and inflammation. As the plaque builds up, it narrows the arteries, reducing blood flow to the heart muscle. When the plaque ruptures, it can form a blood clot that further obstructs the artery, potentially leading to a heart attack (myocardial infarction). Several risk factors contribute to the development of CAD. Some are modifiable, while others are not. Modifiable risk factors .[3,4].

Persistent high blood pressure can damage the coronary arteries, accelerating the process of atherosclerosis. Elevated levels of low-density lipoprotein (LDL) cholesterol can lead to plaque formation in the arteries. Tobacco smoke damages the endothelium and promotes plaque buildup.High blood sugar levels can harm the blood vessels and increase the risk of CAD.Excess body weight is associated with higher levels of cholesterol, blood pressure, and diabetes.Lack of exercise contributes to obesity and other risk factors for CAD.Diets high in saturated fats, trans fats, and cholesterol can increase the risk of atherosclerosis.The risk of CAD increases with age.[5,6].

A thorough assessment of symptoms, risk factors, and family history.A test that records the electrical activity of the heart and can detect abnormalities.Monitors the heart's activity during physical exertion or medication-induced stress.An ultrasound of the heart that provides images of the heart's structure and function.A specialized X-ray test that uses a contrast dye to visualize the coronary arteries and identify blockages.Treatment and Prevention of Coronary Artery Disease.The treatment of CAD aims to relieve symptoms, improve quality of life, and reduce the risk of heart attacks and other complications. Treatment options include. Adopting a heart-healthy diet, engaging in regular physical activity, quitting smoking, and managing stress.Drugs to lower cholesterol (statins), reduce blood pressure (antihypertensives), prevent blood clots (antiplatelets), and alleviate chest pain (nitrates).In severe cases, procedures such as angioplasty (to open narrowed arteries) and coronary artery bypass grafting (CABG, to bypass blocked arteries) may be necessary.Prevention is key in managing CAD. This includes regular health check-ups, maintaining a healthy lifestyle, and addressing risk factors.[9,10].

Conclusion

 

Coronary artery disease remains a major public health concern, but with increased awareness, early detection, and appropriate management, its impact can be significantly reduced. Understanding the heart's anatomy, recognizing risk factors, and adopting preventive measures are vital steps in combating this disease. By prioritizing heart health, individuals can improve their quality of life and reduce the likelihood of severe cardiovascular events.
