Introduction

The coronary arteries play a pivotal role in sustaining the heart's function, serving as its primary source of oxygen and nutrients. These vital blood vessels, often referred to as the "lifeline of the heart," supply oxygen-rich blood to the myocardium, the muscular tissue of the heart responsible for its rhythmic contractions. Understanding the structure, function, and potential disorders of the coronary arteries is crucial for comprehending cardiovascular health and disease the Left Coronary Artery (LCA) and the Right Coronary Artery (RCA). The LCA further divides into the left anterior descending artery (LAD) and the left circumflex artery (LCx). These arteries traverse the heart's surface, supplying blood to various regions of the myocardium.[1,2].

The LAD primarily nourishes the anterior wall of the left ventricle and a portion of the interventricular septum, while the LCx supplies blood to the lateral wall of the left ventricle. The RCA, on the other hand, predominantly feeds the right ventricle, the inferior wall of the left ventricle, and the atrioventricular node, which is responsible for regulating the heart's electrical impulses.The coronary arteries ensure that the heart receives an adequate supply of oxygen and nutrients, facilitating its continuous pumping action. During periods of increased demand, such as physical activity or stress, these arteries dilate to enhance blood flow, ensuring the heart has the necessary resources to meet its metabolic needs [3,4].

Coronary Artery Disease (CAD) represents a common and potentially life-threatening condition characterized by the narrowing or blockage of the coronary arteries due to the buildup of plaque—a mixture of cholesterol, fat, and cellular debris. This process, known as atherosclerosis, restricts blood flow to the heart muscle, leading to ischemia (insufficient oxygen supply) and, in severe cases, myocardial infarction (heart attack).Various risk factors contribute to the development of CAD, including hypertension, high cholesterol levels, diabetes, smoking, obesity, and a sedentary lifestyle. Additionally, genetic predispositions and age play significant roles in predisposing individuals to this condition. The symptoms of CAD can vary widely, ranging from chest pain (angina) and shortness of breath to fatigue, palpitations, and even sudden cardiac arrest. Prompt diagnosis and management of CAD are essential to mitigate its progression and reduce the risk of adverse cardiovascular events.[5,6].

 

Numerous diagnostic modalities are available to evaluate the coronary arteries and assess their patency and function. A non-invasive test that records the heart's electrical activity, helping identify abnormalities indicative of ischemia or previous heart damage. Utilizes sound waves to produce images of the heart's structure and function, enabling the assessment of coronary artery blood flow and detecting any abnormalities.Involves inducing physical or pharmacological stress while monitoring the heart's response, aiding in the detection of ischemia or abnormalities in coronary artery function.Considered the gold standard for diagnosing CAD, coronary angiography involves injecting a contrast dye into the coronary arteries and capturing X-ray images to visualize any blockages or narrowing.Provides detailed images of the coronary arteries using computed tomography, aiding in the assessment of coronary artery anatomy and detecting any abnormalities or blockages.The management of CAD aims to relieve symptoms, prevent complications, and reduce the risk of adverse cardiovascular events.[7,8].

 

 

Adopting a heart-healthy lifestyle through regular exercise, a balanced diet low in saturated fats and cholesterol, smoking cessation, and weight management can significantly reduce the risk of CAD progression.Pharmacological interventions such as antiplatelet agents, statins, beta-blockers, ACE inhibitors, and calcium channel blockers may be prescribed to control blood pressure, lower cholesterol levels, prevent blood clot formation, and improve cardiac function.In cases of severe coronary artery stenosis or blockage, interventional procedures such as percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) may be necessary to restore blood flow to the heart muscle and alleviate symptoms.A comprehensive program involving exercise training, dietary counseling, and psychosocial support can aid in the recovery and management of CAD, improving overall cardiovascular health and quality of life.[
