Question | Answer |
Atherosclerosis leads to | heart attack/stroke |
diff btw Arteriosclerosis & Atherosclerosis | normal part of aging vs accumulations of lipids/plaques |
Arteriosclerosis | hardening of arteries |

Primary HTN | No specific etiology, 90-95% |
Primary HTN-r/t | age, gender, family hx, ethnicity, sedentary lifestyle, socioeconomic status, stress, obesity, alcohol, smoking, diabetes, elevated lipid levels, high sodium diet |
Secondary HTN | specific cause identified & corrected, 5-10% |
Secondary HTN-r/t | renovascular, cushing’s disease, oral contraceptives, primary aldosteronism, renin secreting tumors, pheochromocytoma |
Most common causes of secondary HTN | renal parenchymal & renovascular disease |
HTN-Clinical manifestations | h/a, epistaxis, dizziness, weight changes, DOE, diaphoresis, palpitations, visual disturbances |
Target Organ disease-organ most impacted by high BP | heart |
HTN-Lifestyle modifications | weight reduction, moderate ETOH intake, regular physical activity, decrease Na intake, adequate potassium/calcium/magnesium intake, stop smoking |
DASH | ^fruits & veggies (10-11 servings), decreased fats (26%,<10%saturated), low fat dairy products, <3,000mg NaCl/day |
HTN-Meds | diuretics, adrenergic inhibitors, vasodilators, ACE inhibitors, ARBs, CCBs |
Metoprolol/Lopressor(adrenergic inhibitor)action | beta-adrenergic blockers, decrease HR/CO, decrease renin release from kidney |
Adrenergic Inhibitors | Alpha 1 receptor blockers, dilate blood vessels, 1st dose phenomenon, NA and fluid retention w/ ^ doses |
1st Dose Phenomenon | 1st dose or dose^ leads to Hypotension |
“Prils” action | vasodialate, decrease aldosterone, ACE in the lining of blood vessels, ACE block enzyme that converts A-I to A-II |
ACE-SE | angioedema(lifethreatening-tongue swelling), hypotension(1st dose effect), hyperkalemia(monitor potassium), cough |
Ischemic Stroke | thrombosis/clot, 85% |
Hemorrhagic Stroke | cerebral aneurysm/vessel blows, 15% |
Can this person receive TPA/Thrombolytics? | not if currently bleeding, hemophiliacs, recent surg, severe^HTN, clotting issues(pt/ptt/inr) |
Stroke Diagnosis | S&S/CT(to check for clot, check labs, then TPA)/MRI |
Stroke-General Sx | numbness of face/arm/leg, weakness/difficulty walking, dizziness, confusion, trouble speaking/suddenly can’t form words, visual disturbances/sudden blackened vision, sudden severe h/a |
Neurological Assessment | LOC(Glasgow coma), pupil response; PERRLA, speech; ability & quality, swallowing ability, motor function, spontaneous, grips, sensory function |
PERRLA | pupils equal round reactive light accommodation |
Swallowing ability-precautions | aspiration prec; no straws, HOB^, consistency of thickening, food on unaffected side |
Famous wheelchair ? | on stronger side |
Stroke-signs/meds/tx | TIA, ASA/Plavix, surgery(carotid endarterectomy, angioplasty, stents), treat HTN, treat atrial fib |
Rehab concepts | repetition of activities encourages new CNS pathways, short/frequent sessions 5x/day 10 min each, assistive devices |
Heart Failure #1 cause | atherosclerosis |
Systolic Failure | ventricle loses ability to contract, heart cannot pump blood adequately |
Diastolic Failure | ventricle loses ability to relax, heart cannot fill properly w/ blood |
HF is due to | decreased myocardial contractility secondary to; CAD,HTN, valvular disorders, hypertropic cardiomyopathy, dysrhythmias, toxic substances, viral syndrome |
Cardiac Output | stroke vol x heart rate |
LV Failure-S&S | lungs; fatigue, SOB, dyspnea, DOE, orthopnea, paroxysmal nocturnal dyspnea, cough, crackles, edema, weight gain |

HF-Diagnosis | CXR, Echocardiogram-EF<50%, BNP-^w/ cardio issues>100 |
HF-Nutritional Therapy | low sodium diet;2000-4000mg/day, fluid restriction;1-2L/day, potassium, magnesium |
HF-1st line Drug Therapy | ACE inhibitors, ARBs |
ACE Inhibitors | promote vasodilatation and diuresis, excretion of Na and retention of K, decrease afterload & preload |
ACE Inhibitors-to balance potassium^ | give two diuretics |
Digitalis (Lanoxin/digoxin) | ^ force of myocardial contraction, slows conduction(HR), enhances diuresis |
Digitalis-interventions | monitor dig level, monitor for dig tox, maintain K w/in normal range(hypoK leads to dig tox-<3.5), monitor BUN & creatinine |
Digoxin-Therapeutic level | 0.5-2.0ng/mL |
Digitalis Toxicity-Early S&S | fatigue, loss of appetite, N/V |
Digitalis Toxicity-Late S&S | bad taste in mouth, confusion, vision changes, rhythm changes |
HF-Patient Education pts | S&S of decompensation, meds, drug-drug interactions, daily weight, smoking cessation, alcohol, cardiac rehab, HF clinics |

BUN | 10-20mg/dL |
Creatinine | 0.7-1.4mg/dL |
Mitral Valve Prolapse | ballooned leaflet back into atrium, valve does not remain closed, results in blood regurgitating back into L atrium |
Mitral Regurgitation | valves don’t close completely, blood flows back into L atrium, effects lungs & RVsevere CHF |
