Cardiac events refer to incidents that affect the heart's function, often leading to serious health issues. Common types include heart attacks, arrhythmias, and heart failure. These events can occur due to various factors, including coronary artery disease, high blood pressure, or lifestyle choices such as poor diet and lack of exercise. Symptoms of cardiac events may include chest pain, shortness of breath, and fatigue. Timely medical intervention is crucial for improving outcomes. Risk factors like age, family history, and smoking can increase the likelihood of experiencing a cardiac event, making awareness and prevention essential for heart health.
