| Question | Answer |
| afterload | pressure the ventricular muscle must generate to overcome the increasing pressure of the aorta |
| causes of angina pectoris | CAD & spasms in the muscle of the arterial walls(rare) |
| unstable angina/preinfarction | everything is longer & worse, much harder to get to go away, occurs @ rest, new onset |
| cardiac index | measure of cardiac output |
| anaerobic metabolism | cell work with no O2, uses sugars & other things available, not good |
| prinzmetal's angina | varient type, caused by spasms in coronary muscles by arteries, don't know why, happens @ rest in cycles |
| stable angina | starts with activity & goes away when @ rest, predictable, often relieved w/ O2, nitro & rest, acute coronary syndrome |
| Modifiable risk factors | elevated blood lipids, obesity, smoking, sedentary lifestyle, diabetes mellitus, sypertension & elevated hormone levels(BC) |
| occlusion of right coronary artery | supplies SA node, posterior & inferior walls, anterior R ventricle wall |
| systole | each contraction of the heart |
| preload | passive stretching force exerted on the ventricular mesucle @ end of diastole |
| stroke volume | blood pumped in 1 stroke/contraction |
| not modifiable risk factors | age, gender, heredity |
| CABG, coronary artery bypass graft | take artery from leg & re-route blood, only lasts about 5 yrs |
| calcium channel blockers | cardiac med, -inotropic(force), -chronotropic(rate), decreases AV conduction, dilates coronary arteries & peripheral vascular resistance, inhibits vascular spasm, for angina, SVT, hypertension, peripheral vascular disease & vascular headaches(migraines) |
| pulse deficit | pulse is @ different rate than the ventricle is contracting (poor peripheral perfusion) |
| signs & symptoms of AMI | 70%-90% chest pain, could be "silent MI" though, radiation pattern, constant, no relief, Hx unstable angina common, ECG changes, dyspnea, anxiety, nausea &/or vomiting, diaphoreis, cyanosis, palpitations, dysrhythmias |
| diastole | each relaxation period after contraction of the heart |
| nitrates, nitrites | cardiac meds, vasodilator(arteries & veins), decreases preload & myocardial oxygen demand, oral, sublingual & transdermal |
| arteriosclerosis | "hardening of the arteries", forming of plaque buildup, medium or large arteries |
| prevention strategies for CAD | nutrition, physical fitness, adequate sleep, modify risk factors, avoid substance abuse, anxiety, stress management & CISM |
| ejection fraction (EF) | % of blood ejected during ventricular contraction |
| triglycerides | should be 200-300 mg/dl |
| AMI complications | arrhythmias, sudden death, congestive heart failure, cardiogenic shock & rupture |
| LDL | takes cholesterol & deposits it into the artery walls, "bad cholesterol", less than 130mg/dl |
| digitalis | cardiac med, used for centuries, derived from foxglove plant, +inotropic(force), -chronotropic(rate), -dromotropic(speed), increased cardiac output, CHF, tachyarrhythmias |
| collateral circulation | effort of vessels around affected area to try to take over & oxygenate, only lasts short time |
| pleural effusion | abnormal collection of fluid in the pleural cavity |
| occlusion of left coronary artery | massive anterolateral MI, anterior wall of L ventricle, lateral L ventricle wall, superior L ventricle |
| -blood supply to AV node variable, 60% of people it rises from R side | -low O2 venous blood from heart drains into 5 different coronary veins & empties into R atrium via coronary sinus |
| total cholesterol | should be less than 200 mg/dl |
| cardiac output | blood pumped in 1 min, = stroke vol x heart rate |
| causes of AMI(acute miocardial infarction) | ASHD, prolonged spasm, embolism, hypoxia, shock, L ventricle most common place to occur, once dead cannot be brought back |
| HDL | takes cholesterol thats removed from artery walls & takes to liver to be excreted, "good cholesterol", greater thatn 35 mg/dl |
| pleuritic chest pain | often varies w/ inspiration & expiration, chest movement & cough |
| ASHD | arteriosclerotic heart disease |
| MONA | treatment for cardiac chest pain, M-morphine, O-oxygen, N-nitro, A-aspirin (not in that order) |
| contractility | force @ which muscles shorten/contract |
| thrombolytics (TBA) | drugs used to dissolve blood clots, has to be done in under 6 hrs from onset of symptoms & under the age of 75 |
| angioplasty | insert catheter, pump up balloon, put in stent (mesh tube) |
| beta adrenergic blockers | cardiac med, -chronotropic(rate), -inotropic(force), -dromotropic(speed), decreases myocardial oxygen consumption & peripheral vascular resistance, for angina, hypertension, dsysrhythmias & vascular headaches(migraines), usually end in "olol" |
| starling's law | increased blood to the heart leads to increased cardiac contrility because the centricles stretch |
| angina symptoms | pain lasts 3-5 mins, chest pressure, squeezing or heaviness, radiation patterns, anxiety, dyspnea, nausea &/or vomiting, diaphoresis |
| ischemia | lack of O2 to a tissue/organ, can be brought back with recirculation |
| atherosclerosis | "hardening of the arteries", forming of plaque buildup, any artery |
| occlusion of left anterior descending coronary artery | anteroseptal MI, anterior wall |
| occlusion of left circumflex coronary artery | lateral wall, sometimes inferior & posterior wall |
