BIO 3503 PATHOPHYSIOLOGY OF CARDIOVASCULAR DISORDER
II TEST JUNE 2024 WITH CORRECT ANSWERS. GRADED A+
1. What is the pathophysiology of hypertension?
- Hypertension is characterized by increased blood pressure due to the narrowing of blood vessels,
increased fluid volume or excessive activation of the renin-angiotensin-aldosterone system.
2. What are the risk factors for developing hypertension?
- Risk factors include obesity, high salt intake, family history, age, and certain chronic conditions, such as
diabetes and kidney disease.
3. How does atherosclerosis contribute to cardiovascular disease?
- Atherosclerosis is the buildup of plaque in the arteries, which can lead to blockages and decreased
blood flow to the heart, brain, or other organs.
4. What role does inflammation play in the development of cardiovascular disease?
- Inflammation can contribute to the formation of plaque in the arteries, and the rupture of plaque can
lead to the formation of blood clots.
5. How does diabetes impact cardiovascular health?
- Diabetes can damage blood vessels and increase the risk of atherosclerosis and cardiovascular disease.
6. What is the role of the endothelium in cardiovascular health?
- The endothelium is a layer of cells that lines blood vessels and plays a key role in regulating blood flow
and vascular tone.
7. How does smoking contribute to cardiovascular disease?
- Smoking damages blood vessels, increases plaque buildup, and raises blood pressure, all of which can
lead to cardiovascular disease.
, 8. What is the pathophysiology of heart failure?
- Heart failure occurs when the heart is unable to pump enough blood to meet the body's needs, leading
to symptoms such as fatigue, shortness of breath, and fluid retention.
9. What are the different types of heart failure?
- Heart failure can be divided into systolic heart failure, where the heart's pumping function is impaired,
and diastolic heart failure, where the heart's ability to relax and fill with blood is impaired.
10. How does myocardial infarction occur?
- Myocardial infarction, or heart attack, occurs when a blockage in a coronary artery deprives the heart
muscle of oxygen, leading to tissue damage.
11. What is the role of cholesterol in cardiovascular disease?
- High levels of cholesterol can lead to the formation of plaque in the arteries, increasing the risk of
atherosclerosis and cardiovascular disease.
12. How does stress impact cardiovascular health?
- Chronic stress can lead to the release of stress hormones, which can raise blood pressure and increase
the risk of cardiovascular disease.
13. What is the pathophysiology of arrhythmias?
- Arrhythmias are abnormal heart rhythms that can occur due to problems with the heart's electrical
system.
14. How does obesity impact cardiovascular health?
- Obesity can increase the risk of hypertension, diabetes, and atherosclerosis, all of which can lead to
cardiovascular disease.
15. What role does genetics play in cardiovascular disease?
- Family history can increase the risk of developing cardiovascular disease, as certain genetic factors can
predispose individuals to conditions such as hypertension and atherosclerosis.
