Description
A collection of useful material for medical and dental students, nurses, pharmacists, and whoever is interested in cardiovascular diseases and pathologies.
Study Set Content:
CHF or Congestive Heart Failure
Congestive Heart failure is a syndrome (not a disease), caused by the impairment of the heart's function as a pump enough blood.
Angina
Angina Pectoris is caused by myocardial ischemia in a result of a coronary artery disease.
It might be also a result of anemia, arrhythmia, or CHF.
Angina has two types; stable angina, and unstable angina.
Stable Angina
Stable Angina's symptoms are precipitated by physical activity and stress, and its symptoms disappear at rest or after nitroglycerin administration.
Unstable Angina
Unstable Angina occurs at rest, with minimal or no physical activity or stress, it's more severe than stable angina and it's unpredictable. Myocardial Infarction is imminent if it's not treated.
Arteriosclerosis
Arteriosclerosis is a disease that causes partial or total blockage of arteries. By thickening, hardening, and loss of elasticity of arteries walls.
Atherosclerosis
Atherosclerosis is a type of arteriosclerosis, when atheromatous plaque build up on the arteries walls.
Nitroglycerin
Nitroglycerin (NG) is from the drug group nitrates, it's mostly used with Angina and other heart diseases. It's a vasodilator, and it works by relaxing the blood vessels so the heart gets more oxygen and doesn't need to work hard to pump blood.
What are the risk factors of atherosclerosis?
Risk factors include abnormal cholesterol levels, elevated levels of inflammatory markers, high blood pressure, diabetes, smoking, obesity, family history, genetic, and an unhealthy diet.
The plaque made up of?
Plaque is made up of fat, cholesterol, calcium, and other substances found in the blood.
When do the atherosclerosis symptoms occur?
Signs and symptoms only occur after severe narrowing or closure impedes blood flow to different organs enough to induce symptoms.
