Study Notes
Hypertension
- Hypertension, or high blood pressure, is a condition where the force of blood against the walls of the arteries is consistently too high.
- Causes include unhealthy lifestyle habits, genetics, age, and certain medical conditions.
- Effects include damage to arteries, heart attacks, strokes, kidney disease, and other serious health issues.
Heart Attack
- A heart attack occurs when the blood flow to the heart is blocked, leading to damage or death of the heart muscle.
- Causes include the buildup of plaque in the coronary arteries, which supply blood to the heart muscle.
- Effects include chest pain or discomfort, shortness of breath, nausea, and sweating.
- Treatment may involve medications to dissolve the clot and restore blood flow, procedures such as angioplasty or stent placement, or surgery in severe cases.
Atherosclerosis
- Atherosclerosis is a condition where fatty deposits build up inside the arteries, narrowing them over time.
- Causes include unhealthy lifestyle habits, genetics, and age.
- Effects include reduced blood flow to organs and tissues, leading to serious health problems like heart attacks, strokes, and peripheral artery disease.
- It can develop slowly over many years, often starting in childhood, and can be prevented by making healthy lifestyle choices.
Thrombosis
- Thrombosis is when a blood clot forms inside a blood vessel and blocks the flow of blood.
- Causes include injury to a blood vessel, slow blood flow, certain medical conditions, and medical treatments.
- Effects include blockage of blood flow to an organ or tissue, causing damage or even death to that area.
- Thrombosis can lead to deep vein thrombosis (DVT) and pulmonary embolism (PE).
Stroke
- A stroke happens when something blocks blood flow to part of the brain or when a blood vessel in the brain bursts.
- Causes include high blood pressure, smoking, and blood clots.
- Effects depend on which part of the brain is affected and can include sudden numbness or weakness, trouble speaking or understanding speech, vision problems, severe headache, and dizziness.
- Treatment may include medications to dissolve blood clots, surgery to repair blood vessels, or rehabilitation to regain lost skills.
Coronary Artery Disease
- Coronary artery disease, or heart disease, affects the heart's blood vessels.
- Causes include unhealthy diet, lack of exercise, smoking, high blood pressure, high cholesterol levels, and diabetes.
- Effects include reduced flow of blood and oxygen to the heart muscle, leading to chest pain or discomfort, and potentially, heart failure.
- It can develop slowly over many years, initially with no symptoms, but leading to serious complications if left untreated.
