A cardiac nurse is a specialized healthcare professional who focuses on patients with heart-related conditions. They work in various settings, including hospitals, clinics, and rehabilitation centers, providing care for individuals with issues such as heart disease, heart failure, and arrhythmias. Their responsibilities include monitoring patients' vital signs, administering medications, and educating patients about heart health. In addition to direct patient care, cardiac nurses collaborate with a team of healthcare providers, including cardiologists and surgeons, to develop and implement treatment plans. They play a crucial role in helping patients manage their conditions and improve their overall quality of life through lifestyle changes and ongoing support.
