cause of secondary HTN | possibly reversible; cardiac, renal and endocrinological problems or vasoconstricting meds = 5% of pts |
Person to likely get HTN | AA female |
Effects of HTN on arteries | high BP causes shearing force on arterial walls which injure endothelium = reaction of vasoconstriction, inflammation, platelet aggregation, lipid deposition = arteriosclerotic plaque formation |
Target organs affected by HTN | brain, eyes, heart, kidneys, and peripheral arteries |
Increased insulin levels affect on BP | increases sympathetic activity (which controls vasoconstriction) and causes hypertensive states |

ASCVD recommends statins for what percentage of risk? | 7.5% |
What do lipoproteins do? | Carry cholesterol in the bloodstream |
How do LDL proteins work? | They go to inflamed areas in the blood vessel wall where they form fatty streaks and atherosclerotic plaques |
Goal LDL and HDL | LDL = less than 40 HDL = more than 60 |
What do HDL proteins do? | removes excess cholesterol from blood vessels to the liver where it is excreted in intestine as bile. |
What is metabolic sydrome | various CVD and DM risk factors where the underlying path is related to insulin resistance |
What conditions make up metabolic syndrome | any 3 of the following: increased BMI, elevated SBP, hypertriglyceridemia, hyperglycemia, lows HDL protein |
What do coronary arteries do | coronary arteries provide arterial blood (O2 & nutrients) to heart and dilate as needed to increase oxygen delivery with changing metabolic demands of heart |
What is Coronary artery disease (CAD)/ coronary heart disease (CHD) | arteriosclerotic plaque hinders optimal blood flor wan dilation of coronary arteries by sticking to coronary artery walls which causes obstruction and prevents vasodilation which impedes perfusion of myocaridum |
angina pectoris cascade | arteriosclerosis prevents coronary vessels from dilation = insufficient O2 being delivered to myocardium=ischemia of heart muscle = anaerobic metabolism which produces lactic acid = tissue acidosis and irritation = chest pain = angina |
What is atherosclerosis/arteriosclerosis | systemic disease affecting all arteries of body |
If the pt presents with exertion angina__ | suspect CAD |
Diagnostic tests for CAD | ECG, stress test, nuclear scanning and angiography can help determine extent of CAD and identify which vessels are affected |
What is Nuclear Scanning | studies motion of left ventricle and measures ability to eject blood (normal ejection fraction is 55-75%). |
Nuclear scanning rundown | When ischemia because of a narrowed artery is present, the part of the myocardium that artery serves shows a diminished wall contractility evidenced by pooled blood in that specific chamber. |
Acute coronary syndrome consists of which dx | myocardial ischemia dx: stable and unstable angina, variant angina, and myocardial infarction |
Stable angina is | predictable, and controlled with meds |
Unstable angina is | newly diagnosed angina or unpredictable in pattern, frequency or severity; may lead up to acute MI |
Population most likely to have an MI | AA men older than 65 |
Stable angina | coronary occlusion that causes brief ischemia but is treatable and reversible |
2 types of MI | STEMI and NSTEMI (non STEMI) |
STEMI | stands for ST elevation myocardial infarction; caused by OCCLUSIVE thrombus that leads to infarction of FULL THICKNESS of myocardial wall |
NSTEMI | stands for non ST elevation myocardial infarction; caused by infarction from NONOCCLUSIVE thrombus that infarcts only PART of myocardial wall |
Diagnostic test for MI | Troponin I and T |
Cardiac Troponin levels | are proteins released from dead heart muscle and are NOT found in people with healthy hearts. Rise in 2-4 hours after MI and remain high for 7-10 days |
ECG finding showing acute coronary artery occlusion | ST-segment elevation more than 1mm ; usually occurs due to thrombus |
ECG finding showing myocardial ischemia | enlarged and inverted t-wave |
ECG finding showing myocardial infarction | abnormal q-wave |
Determine the location of myocardial damage and which coronary artery is damaged by | seeing which ECG lead has the abnormality |
Manage stable angina | Nitro and rest, attacks normally 3-5 minutes and go away with treatment; if they don't go to ER |
Heart failure is | cardiac output cannot meet body's demands |
Systolic dysfunction of heart failure | ventricles can't eject an adequate amount of blood; left ventricle EF is less than 50% |
Diastolic dysfunction of heart failure | ventricles can't fill up with sufficient amount of blood; let ventricle EF is 70% or more |
Systolic dysfunction cascade/ forward failure | weak ventricles eject small amount of blood = hypoperfusion = stimulates sympathetic nervous system to constrict arteries and provoke renin angiotensin cascade = increased BP and blood volume = more work on ventricles |
Diastolic dysfunction cascade/backward failure | elevated filling pressure builds up in ventricle. In let ventricle, blood builds up and goes into left atrium then pulmonary system = pulmonary edema; |
Pulmonary edema signs | pink frothy sputum, dyspnea, cough, crackles |
Left Ventricular Failure/left sided heart failure | most common type; HTN increases the resistance against the left ventricle resulting in increased workload which leads to left ventricular hypertrophy. |
Normal ejection fraction | 55-70% |
Right sided heart failure/ right ventricle failure | leads to venous system congestions; congestion of superior vena cava=jugular vein dissension; congestion of inferior vena cava= hepatomegaly, splenomegaly, and peritoneal edema (ascites) |
Cor pulmonale | right sided heart failure from increased pulmonary HTN d/t chronic hypoxemia. the HTN causes right ventricle hypertrophy but the ventricle eventually fails and this failure is called cor pulmonate |
Atrial natriuretic peptide (ANP) is secreted when___ | atrial stretch d/t increased hydrostatic pressure occurs; happens in heart failure |
B-type natriuretic peptide (BNP) | rises in presence of heart failure, above 500 pg/ml= HF, |
Best test to confirm heart failure | ECG, done after a BNP |
How to manage heart failure | ACEI (if not tolerated then ARB), diuretics for volume overload (thiazide for mild HF and loop for severe), beta blocker to slow HR and decrease work of heart |
When to notify PCM with weight gain in heart failure | more than 3 pounds in a day or 5 pounds a week |

premature atrial contractions (PAC) | usually insignificant and occur in young people who drink too much caffeine, nicotine, or alcohol, or other stimulant - no treatment |
Digoxin affect on arrythmias | commonly causes AV blocks and b/c it has a narrow therapeutic window, toxicity occurs easily which can cause arrhythmia of any kind. |
A fib ECG strip findings | irregularly irregular heart beat, 100-180 beats per min from ventricle rate, 350-600 beats per min for atrial rate, no discernible p waves, QRS usually normal |
PAC ECG findings | rate of 60-100, regular rhythm until premature beat, |
SVT ECG findings | regular rhythm w/ rate of 150-250 beats per minute |
A flutter ECG findings | atrial rate of 250=350 beats per min, p waves march out, |
PVS ECG findings | rate of 60-100 beats per min, QRS complex is wide and bizarre |
anticoagulation in A-fib | started when pt's are afib longer than 48 hrs; warfarin will be started draw PT and INR; goal INR 2-3, check INR weekly until established then check monthly |
Treat A fib | amiodarone to covert to NSR, synchronized cardioversion if pt in distress |
SVT treatment | vagal maneuvers, adenosine rapid IV push in emergency, synchronized cardio version for symptomatic pts |

Definitive procedure to diagnose heart valve disorders | 2 dimensional echocardiography |
Peripheral Artery Disease (PAD) most common manifestation | lower extremity claudication - cramping pain that starts with activity and is relieved by rest |
Pathophysiology of PAD | usually caused by atherosclerosis, plaque builds up and obstructs blood flow to lower extremity muscles. When muscles start to move they need more oxygen via blood but cannot get it = pain d/t ischemia |
Sign of severe PAD | pain at rest, weak pulse, pallor, paresthesia, coolness of extremity, muscle atrophy, diminished hair growth, hard discolored toenails |
how to tell difference between chronic venous insufficiency and PAD | raise pt's legs for several minutes, when they are placed down again PAD= pale dusky red extremities venous insufficiency = improved color |
