Cardiac care in nursing involves a combination of lifestyle modifications, pharmacological management, and interventional procedures. Nurses educate patients on the importance of a heart-healthy diet, regular exercise, smoking cessation, and stress management. Medications such as beta-blockers, ACE inhibitors, diuretics, and anticoagulants are commonly used to manage cardiac conditions. Interventional procedures, including angioplasty, stent placement, and coronary artery bypass grafting (CABG), may be necessary for severe cases.
