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