Study Notes
High Blood Pressure
- Blood pressure measures the force used to pump blood through arteries.
- High blood pressure, or hypertension, leads to potential damages such as heart disease, stroke, or kidney disease.
Atherosclerosis and Coronary Artery Disease
- Atherosclerosis is the hardening of arteries due to plaque buildup, comprised of cholesterol, fat, and calcium.
- Coronary artery disease results from narrowed and hardened arteries, often without noticeable symptoms initially.
- Symptoms may include chest pain or heaviness, indicating reduced blood flow.
Heart Attacks
- Occur when blood supply to the heart is insufficient, often due to artery blockage.
- Symptoms include:
- Chest pain or discomfort, possibly feeling like pressure or fullness.
- Pain radiating to the jaw, shoulder, arm, or back.
- Shortness of breath, sweating, nausea, and irregular heartbeat.
- In severe cases, may lead to unconsciousness.
Heart Failure
- Also referred to as congestive heart failure, occurs when the heart muscle is weakened and cannot pump sufficient blood.
- Typically follows other heart issues, such as heart attacks or coronary artery disease.
- Early symptoms include fatigue, swollen ankles, and increased nighttime urination.
- Severe symptoms can escalate to rapid breathing and chest pain.
Strokes
- Stroke happens when a blood clot blocks an artery in the brain or a blood vessel ruptures.
- This reduces blood and oxygen supply to brain regions, resulting in potential damage.
Abdominal Aortic Aneurisms
- An abdominal aortic aneurism is a bulge in a weakened section of the aorta, a major blood vessel supplying blood to the body.
