Diseases of the Cardiovascular System Chapter 6
| Question | Answer |
|---|---|
| AP(Angina pectoris) is characterized by | thoracodynia(chest pain) resulting from myocardial ischemia(starvation of oxygen) |
| The myocardial ischemia is commonly caused by | CAD(Coronary Artery Disease) |
| The lumen is the | inside diameter of the artery |
| The purpose of the coronary arteries is to | deliver oxygenated blood to the myocardium(muscle layer of the heart) |
| When an embolus(floating clot) occludes(obstructs/infarcts) a coronary artery the resulting injury is called a | MI(Myocardial Infarction) |
| If the ischemia is not corrected, death can occur to the myocardian called | myocardial necrosis |
| Dx(diagnosis) of a MI(myocardial infarction) is made by | 1.EKG or ECG(ElectroCardioGram) 2.CPK-MB (cardiac isoenzymes)---blood test 3.Troponin levels)---blood test |
| CAD(Coronary Artery Disease) is AKA | CHD(Coronary Heart Disease) causing stenosis(narrowing) |
| The stenosis (narrowing) in CAD(Coronary Artery Disease)/ CHD(Coronary Heart Disease) is caused by | Atherosclerosis ----fatty plaque that forms on the lumen of the coronary arteries |
| A MI(myocaridal Infarction) is commonly called a | "heart attack" or "coronary" |
| The starvation of oxygenated blood to the myocardium is called | myocardial ischemia(starving) |
| Risk factors for CAD(Coronary Artery Disease) include | 1.Heredity 2.Smoking 3.High fat diet(cholesterol, LDL(LowDensity Lipoproteins) & triglycerides 4.Sedentary Life style(obesity,little or no excerise);>40 inch waist for men,>35 inch waist for women 5.Over age 35 6.Poorly controlled stress |
| #2 Risk Factors for CAD(Coronary Artery Disease) | 7.Chronic HTN(hypertension 8.DM(Diabetes Mellitus) 9.Elevated CRP(C-reative protein) |
| Tx for CAD(Coronary Artery Disease) include | *.Stop smoking*.Lower Saturated fat in diet & increase HDL(HighDensityLipoproteins)/omega-3 fatty acids*.Regular exercise(walk) *.Antianginal drugs(coronary vasodilator increases diameter)*.Antihyperlipidemic(against excessive fat in blood |
| Tx for CAD(Coronary Artery Disease) include cont. | *.Thrombolytics(breakup clots that occluded coronary arteries*Anticoagulants-prevent new thrombi forming*PTCA(Percutaneous Trans-luminalCoronaryAngioplasty*Coronary stents-prevent closure after angioplasty*CABG*EECP-EnhancedEsternalCounterPulsation |
| CABG stands for | Coronary Artery Bypass Graph |
| CABG (Coronary Artery Bypass Graph commonly uses grafts harvested from the | saphenous veins or mammory arteries & used to bypass stenosed(narrowed)or occluded coronary arteries |
| Types of CABG include | double, triple, quadruple, or quintuple by passes |
| Common Signs & symptoms of MI(myocardium Infarction) or AP(Angina Pectorus) include | *Thoracodynia(chest pain)*Dypnea(difficult breathing*Pallor/paleness*N&V*Diaphoresis/profuse sweating*Weakness*Syncope/faint |
| Best chance of surving a MI(myocardium infarction) depends on whether the infarct is resolved within | 90 minutes |
| EECP -Enhanced External Counter Pulsation uses | inflatable cuffs on the lower extremities inflating & deflating in rhythm w/the heart to increase oxygenated blood flow to the coronary arteries & stimulate development of collarteral(extra) blood vessels |
| CAD(Coronary Artery Disease) risk can also be reduced by | 1.Drinking tea daily(flavanoids) 2.Getting 300 MCG of folate/day(tomatoes, citrus,leafy greens, beans, grains) |
| CHF(Congestive Heart Failure) is caused by a | weak pump |
| There can be any combination of signs & symptoms or the victim may be | asymptomatic(No symptoms) |
| An asymptpmatic MI is AKA | silent MI(myocardium infarction)/most dangerous because the victim has no reason to seek help |
| STEMI times refers to the | time between a ST(stemi time) elevation MI(myocardium infarction) (EKG normal sinus rhythm(NSR) |
| PTCA stands for | Percutaneous Transluminal Coronary Angioplasty |
| Causes of CHF(Congestive Heart Failure) | *MI(myocardial infarction)*Myocardial atrophy from a sedentary life style/obesity*Valvular disease(valves are bad)*Chornic HTN(HyperTension/high blood pressure) |
