Coronary artery disease |
Coronary artery disease is a vascular disorder, it is when the coronary artery's are narrowed or occluded by 50% or more |
|
|
Nitrates |
Cause peripheral vasodilation. Decreased vascular resistance in there for decreased cardiac workload. |
|
|
Beta –adrenergenic- receptor blockers |
Reduces heart rate. Reduces workload of the heart and therefore reduces the demand for O2. |
|
|
Calcium channel blocker's |
Increase Vasodilation, decrease HR. |
|
|
Percutaneous coronary intervention |
Manual dilation of coronary vessels with the catheter. |
|
|
Coronary artery bypass |
Surgical procedure. |
|
|
Dislipidemia |
Abnormal lipoproteins in blood |
|
|
Lipoproteins |
Proteins, phospholipids, triglycerides, cholesterol. |
|
|
LDL- low density lipoproteins |
Made by the liver. Transport lipids from the liver to tissue. |
|
|
HDL- high density lipoprotein |
Transport high density lipoproteins. Transports lipids in adipose tissue to the liver for degradation. More proteins less fats. |
|
|
Non-modifiable risk factors for coronary artery disease |
Genetics, race, gender, age. |
|
|
Modify the risk factors for coronary artery disease |
Hypertension, smoking, diabetes, metabolic. |
|
|
Agina pectoris |
Painful cramping caused by the lack of O2. |
|
|
Cardiac ischemia |
Lack of O2 to cardiac muscles |
|
|
Cardiac arrest |
The heart literally stops pumping |
|
|
Myocardial infarction- a heart attack |
May lead to cardiac arrest, but it's defined as a sudden event where at least one of the three major coronary artery's becomes partially or totally block, usually by a blood clot (Thrombosis) |
|
|
Three major coronary arteries |
Right coronary artery, left descending coronary artery, and the left circumflex artery. |
|
|
Heart cells can live ___ before necrosis. |
20 minutes |
|
|
The area of infarction |
Where necrosis occurs, if it does. Surrounding it is the area of injury, which may or may not suffered permanent damage. The outermost zone of ischemia is the weekend but regains function within two or three weeks. |
|
|
What is the number one cause of heart attacks? |
Coronary artery disease and accompanying atherosclerosis. |
