treatment hypoglycemia
oral glucose, IV glucose, glucagon (IM or SC)
88
diabetic ketoacidosis
serious complication of diabetes that occurs when the body produces high levels of blood acids called ketones
89
diabetic ketoacidosis develops when
the body can not produce enough insulin
90
without enough insulin, what happens (diabetic ketoacidosis)
body begins to break down fat as fuel
91
diabetic ketoacidosis produces
a buildup of acids in the bloodstream called ketones, eventually leading to DK
92
DKA (muscle cells
muscle cells become starved for energy, your body may respond by breaking down fat stores
process forms toxic acids known as ketones
left untreated, diabetic ketoacidosis leads to coma

181
angina is
recurring chest pain or discomfort
182
angina occurs when
heart muscle (myocardium) doesn't receive enough blood and oxygen to meet body needs
183
symptoms of angina
- a pressing, squeezing, or crushing pain, usually in chest under sternum
- pain radiating in arms, shoulders, jaw, neck
- weakness/fatigue
- occurs in response to exertion and is relieved by rest
- lasts 3-5 mins
- emotional stress may cause
184
causes of angina
- occurs when the heart's workload (and need for oxygen) exceeds the ability of the coronary arteries to supply
- coronary blood flow can be limited when the arteries are narrowed by atherosclerosis
185
stable angina
- chest pain or discomfort that typically occurs when activity or stress
- episodes of pain or discomfort are provoked by similar or consistent amounts activity or stress
186
unstable angina
pattern of symptoms change
- usually angina stays constant, any change is serious
- change reflects sudden narrowing of a coronary artery bc an atheroma has ruptured or a clot as formed
- risk of heart attack is high
- considered an acute coronary syndrome
187
angina diagnosis
- complete medical history
- ECG
- stress test
- echocardiography
- CT
- cardiac catheterization
188
echocardiography
uses ultrasound waves to produce images of the heart, shows heart size, movement of muscles, blood flow through heart valves, and valve function
189
cardiac catheterization
contrast agent is injected into an artery & x-rays are taken to locate narrowing, occulsions, and other abnormalities
190
treatment for angina
- attempts to slow/reverse the progression of coronary artery disease by dealing with risk factors
- quitting smoking is crucial
- a low-fat, varied diet that's low in carbs & exercise are recommended
- weight loss if needed
191
risk factors for angina
hypertension, high cholesterol levels
192
medical treatments for angina
- nitrates (nitroglycerine spray)
- beta-blockers (metoprolol)
- calcium channel blockers (verapamil)
- antiplatelet drugs (aspirin)
- percutaneous coronary intervention (balloon angioplasty, stent)
- coronary artery bypass graft surgery
193
what are the leading causes of death in canada
heart disease & stroke
194
most deaths from heart attacks are caused by
ventricular fibrillation of heart
195
what is the % of survival if you make it to the ED w/ MI
90%
196
heart attack symptoms
- chest pain or pressure
- pain
- fullness
- squeezing sensation of chest
- jaw pain
- toothache
- headache
197
what is heart attack
death of heart muscle from the sudden blockage of a coronary artery by a blood clot
198
blockage of a coronary artery deprives the heart muscle of
blood and oxygen, causing injury to the muscle, injury to the heart muscle causes chest pain and chest pressure sensation
199
if blood flow is not restored to the heart muscle within
20-40 mins, irreversible death of heart muscle begins
200
causes of heart attack
- atherosclerosis
201
atherosclerosis
- gradual process = cholesterol plaques deposited in walls of arteries
- plaques cause hardening of walls & narrowing of inner channel of artery
- those arteries cant deliver enough blood to maintain normal function of parts of body they supply
202
problem with atherosclerosis
can be silent (no symptoms)
203
what can accelerate early atherosclerosis
smoking, hypertension, elevated cholesterol, diabetes mellitus especially if there is family history of early onset
204
the cause of the rupture of plaque to causes the formation of the clot is unknown but contributing factors include
nicotine exposure, elevated LDL cholesterol, elevated levels of adrenaline, hypertension
205
more heart attacks occur b/w
4am-10am because of the higher blood levels od adrenaline released from the adrenal glands
206
symptoms of heart attack
- chest pain/pressure
- jaw pain, toothache, headache
- nausea, vomiting, epigastric discomfort
- heartburn/indigestion
- arm pain (left arm)
- upper back pain
- general malaise (vague feeling of illness)
- asymptomatic (common in diabetes mellitus)
207
women are more likely to have atypical heart attack symptoms like
- neck & shoulder pain
- abdominal pain
- nausea
- vomiting
- fatigue
- shortness of breath
208
what are the complications of a heart attack
- heart failure
- large amount of muscle dies, ability to pump blood to the rest of body is diminished
- body retains fluid
209
cholesterol that is combined with low-density lipoproteins (LDL) is the
"bad" cholesterol that deposits cholesterol in arterial plaques = elevated levels of LDL cholesterol associated w/ increased risk of heart attack
210
cholesterol combined with HDL is the
"good" cholesterol = decreases risk of heart attack
211
family history of heart disease
- ppl w/ history have increased risk of heart attack
- higher risk of early coronary heart disease including heart attack or sudden death before age 55 in males & before 65 in female
212
how is a heart attack diagnosed?
ECG, blood tests
213
what are cardiac enzymes
proteins that are released into the blood by dying heart muscles
214
what are the cardiac enzymes
creatine phosphokinase (CPK) & troponin
215
series of blood tests for the enzymes performed over a 24hr period are useful not only in confirming the diagnosis of a heart but...
the changes in their levels over time also correlates with the amount of heart muscle that has died
216
people who think they are having heart attack should
- chew 2 aspirins STAT after calling 911
- increases chances of survival by reducing the size of the clot
217
decreasing the hearts workload also helps limit tissue damage, what is given to do this
beta-blocker to slow heart rate
- slowing heart rate enables the heart to work less hard and reduce the area of damaged tissue
218
most ppl also given what for heart attack
anticoagulant drug (heparin) to help prevent the formation of additional blood clots
219
medical treatment options for heart attack
- O2 given via nasal prongs = providing more O2 to heart helps keep tissue damage min
- ppl experiencing extreme discomfort = morphine used to calm and reduce workload
- given nitroglycerine = relieves pain by reducing the workload of heart & possibly by dilating arteries
220
heart failure occurs
when heart muscle becomes weak & can't pump enough blood to meet the body's needs = not enough blood flow to provide the body's organs with O2 & nutritions
221
term heart failure means
heart is not working efficiently
222
how does the heart compensate for heart failure
beats faster or more forcefully but eventually these fail & heart becomes more & more impaired
223
heart failure results from a condition that
forces the heart to work harder & faster to keep blood flowing & may involve right, left, or both sides
224
there are 2 basic problems in heart failure
systolic dysfunction, diastolic dysfunction
225
systolic dysfunction
occurs when the heart can't pump enough blood to supply all the body's needs
226
diastolic dysfunction
occurs when the heart cant accept all the blood being sent to it
227
causes of heart failure
- coronary artery disease
- persistent hypertension
- heart attack
- diabetes
- arrhythmias
- heart valve disease
- heart valve damage
- viral infection
- an enlarged wall
- certain kidney conditions
228
coronary artery disease (CAD)
condition that causes narrowing of arteries that supply the heart with blood, can damage & weaken
229
persistent hypertension
forces the heart to pump against higher pressure, which causes it to weaken over time
230
arrhythmias
abnormal heart rhythms causing pump inefficiently
231
heart valve disease
caused by abnormalities been present since birth or developed over time
232
heart valve damage
caused by rheumatic disease or infection
233
viral infection
of heart muscle can weaken heart
234
enlarged wall
b/w heart chambers (genetic condition) may be cause
235
certain kidney conditions
increase BP & fluid buildup can increase the risk of HF by placing more stress on heart
236
the heart compensates in 3 ways for HF
- dilating (enlarging) to form a bigger pump
- adding new muscle tissue to pump harder
- beating at a faster rate
237
appearance of HF symptoms can be
delayed for years bc heart tries to compensate
238
as the heart compensates, several things happen...
- heart can't pump well enough to pump blood through body & back to heart again
- blood backs up into legs & lungs, causing fluid build up = edema of ankles & legs, shortness of breath (pulmonary edema)
239
right-sided HF
blood backs up into body
240
right-sided HF causes...
edema of feet, ankles, & legs = leading to frequent urination at night, sudden weight gain, weakness, vertigo, painful stomach bloating
241
left-sided HF
pulmonary edema can cause breathing problems = SOB, dyspnea (lying down), wheezing, coughing up blood tinged mucus, a dry cough, weakness, chest pain, rapid pulse
242
diagnosing HF
exam to check for edema in legs & fluid in lungs
- dr order blood & urine tests, ECG, chest xray
243
ejection fraction
proportion of blood that gets pumped out
244
treating & preventing HF
- managed with lifestyle adjustments & medication
- cutting back on fluids
- staying active but avoiding triggering HF symptoms
- lower sodium intake to 2.3g daily (less sodium reduces fluid retention)
- wearing special elastic stockings = reduce swelling in legs caused by fluid retention
- weight management program
245
HF can be treated with the following medications
- ace inhibitors
- angiotensin receptor blockers
- certain beta-blockers
246
ace inhibitors
expand blood vessels, allowing blood to flow more easily & making the heart's work easier or more efficient
247
angiotensin receptor blockers
useful in place of ACE inhibitors when they can't be used or sometimes in addition
248
certain beta-blockers
(metoprolol, bisoprolol)
- proven to help improve heart function
249
digoxin increases the
force of the pumping action of the heart
250
diuretics (furosemide) help the body
elimiate excess salt & water
251
ways to maintain/improve heart health
- control hypertension
- eat a healthy diet
- exercise
- maintain blood sugar
- maintain healthy cholesterol levels
- quit smoking
252

263
ST elevation myocardial infarction (STEMI) refers to
ST segment elevation of a pts ECG who generally have cardiac biomarkers (elevated troponin level) which indicate necrosis of heart muscle
264
management of STEMI focuses on
early reperfusion therapy by thrombolytic or revascularisation w/ percutaneous coronary intervention
