A leading cause of morbidity and mortality worldwide, ischemic heart diseases develop when insufficient blood supply to the heart muscle compromises its function. The condition often stems from plaque buildup within the coronary arteries, reducing oxygen delivery and causing ischemic damage. Patients may experience silent symptoms or acute events such as angina or myocardial infarction. Effective management of ischemic heart diseases combines risk factor control, such as smoking cessation and cholesterol management, with advanced medical and surgical treatments. Modern cardiology continues to refine techniques to restore and preserve heart function, offering hope to millions affected by this condition. Raising awareness and promoting preventive strategies remain critical in reducing the global burden of this disease.
