Background. One of the most common cardiovascular diseases is coronary artery disease, which occurs when there is a buildup of plaque in the arteries that supply blood to the heart. CAD, or coronary artery disease, is a type of cardiovascular disease characterized by the narrowing or blockage of the coronary arteries that supply oxygen-rich blood to the heart. This narrowing or blockage is typically caused by the accumulation of cholesterol and other materials, which form a buildup called plaque on the inner walls of the arteries.The prevalence of risk variables in healthy people demonstrates the likelihood of CAD soon. Echocardiography is the most commonly used method to assess cardiac function through different modes and modalities. This is due to many factors including easy access, non-invasiveness, and the huge progress resulted in better, more accurate results. The relationship between left ventricular function and the degree of coronary artery disease in patients with and without a history of myocardial infarction was examined in 96 patients who reported chest pain. Coronary artery disease alters diastolic function to varying degrees. Following myocardial infarction and acute ischemia, certain anomalies are generated. In these two diseases, the etiology of diastolic anomalies is discussed. The left ventricle's filling pressures rise during acute ischemia. Pulmonary oedema could develop. Less of a rise in filling pressures results with silent ischemia. With varying contributions from altered myocardial relaxation, increased muscular stiffness, acute pericardial constriction, ventricular interaction, and acute chamber dilatation, the diastolic pressure-volume ratio is moved upward. Because of the factors that change the pressure-volume relationship, the left ventricle's ability to fill during ischemia is altered. Given the decreased left ventricular compliance, the abrupt rise in left atrial pressure may raise filling rates relatively unexpectedly
