Heart issues refer to a range of problems that affect the heart and its ability to function properly. Common conditions include coronary artery disease, where the arteries become narrowed or blocked, and arrhythmias, which are irregular heartbeats. These issues can lead to symptoms like chest pain, shortness of breath, and fatigue. Risk factors for heart issues include high blood pressure, high cholesterol, obesity, and a sedentary lifestyle. Maintaining a healthy diet, exercising regularly, and avoiding smoking can help reduce the risk of developing these conditions. Regular check-ups with a healthcare provider are also important for early detection and management.
