Inflammation is the process by which your body protects you from infection but unregulated becomes a disease. Symptoms include redness, swelling, pain, and stiffness. Chronic inflammation has been linked to diseases like heart disease or stroke, and may also lead to autoimmune disorders.

Cardiovascular disease typically refers to narrowed or blocked blood vessels. Other heart conditions can affect the heart’s muscle, valves or rhythm. Symptoms may include fatigue, shortness of breath, irregular heartbeat, swollen feet or ankles, fainting, or chest pain.
