CCU stands for "Coronary Care Unit". In a hospital setting, the CCU is a specialized unit dedicated to the care of patients with serious and life-threatening heart conditions. This unit is staffed by healthcare professionals who have specialized training in cardiac care and are equipped with advanced technology and equipment to monitor and treat patients with heart problems. Patients who are admitted to the CCU typically require intensive monitoring, medication, and other interventions to manage their condition and stabilize their heart function. The CCU is a critical component of modern healthcare and has contributed significantly to the improvement of patient outcomes in the management of cardiac diseases.
