1. Cardiac failure: Also known as heart failure, this condition occurs when the heart is unable to pump enough blood to meet the body's needs. Symptoms may include shortness of breath, fatigue, and swelling in the legs and abdomen.

2. Angina pectoris: This is chest pain or discomfort that occurs when the heart muscle does not receive enough oxygen-rich blood. It is often a symptom of coronary artery disease.

3. Myocardial infarction: Commonly known as a heart attack, this occurs when blood flow to a part of the heart is blocked, leading to damage or death of the heart muscle.

4. Arteriosclerosis: This is a general term for the thickening and hardening of the arteries, which can restrict blood flow and increase the risk of cardiovascular events such as heart attacks and strokes.

5. Atherosclerosis: This is a specific type of arteriosclerosis in which plaque builds up inside the arteries, leading to narrowing and hardening of the blood vessels. This can increase the risk of heart attacks and strokes.

6. Aneurysm: This is a bulge or weakness in a blood vessel that can rupture and cause internal bleeding. Aneurysms can occur in various parts of the body, including the heart and arteries.
