Cardiac Flashcards
Preload
The amount of blood returning to the RIGHT side of the heart and the muscle stretch that the volume causes. ANP is released when we have this stretch
Afterload
The pressure in the aorta and peripheral arteries that the left ventricle has to pump against to get blood out
This pressure is referred to as resistance
With hypertension there is even more resistance to pump against thats why HTN can eventually lead to HF and pulmonary edema, because high afterload decreases cardiac output and decreases the forward flow, in addition to wearing out your heart.
Stroke volume
The volume of blood pumped out of the ventricles with each beat
Cardiac Output
Tissue perfusion is dependent on an adequate cardiac output. Cardiac output changes according to the body’s needs
Factors that affect Cardiac Output
Heart rate and arrhythmia’s such as A.fib, Tachycardia and Bradycardia.
Blood Loss = Less volume, Less pressure (less perfusion). More volume, more pressure.
Ineffective contractility due to MI, cardiac muscle disease , medication
Angiotensin- converting Enzyme (ACE) Inhibitors
Captopril (Capoten), Enalapril (Vasotec), Lisinopril (Zestril, Prinivil), Moexipril (Univasc), Ramipril (Altace)
Commonly used for Heart failure, HTN and MI
PO/IV
1-2 hours/ 15-30 minutes
Interactions: Hyperkalemia can result if takein in combination with potassium sparing diuretics or eating salt substances
MoA:Suppress the Renin Angiotensin System (RAS). Prevents the conversion of Angiotensin I to Angiotensin II. This results in arterial dilation (decreasing the afterload) and increased stroke volume. ACE inhibitors block aldosterone so the client loses sodium and water and retains potassium. ACE inhibitors improve lung function by increasing alveolar-capillaries membrane diffusing capacity and pulmonary function in patients with HF.
Advantages: Effective in treating heart failure
Disadvantages: African Americans and older adults do not respond to ACE inhibitors with the desired reduction in blood pressure without the addition of a diuretic
Side effects: Dizziness Hyperkalemia Hypermagnesemia Fatigue Headache Dry, nonproductive cough
Adverse effects: Angioedema, Orthostatic hypotension
Interventions:
Monitor BP and HR.
Monitor potassium and magnesium levels.
Initiate safety precautions.
Education:
Rise slowly from lying or sitting to standing position.
Safety precautions.
Can be administered with food (EXCEPT: Moexipril)
Do not use salt substitutes with potassium.
Angiotensin 2 Receptor Blockers (ARBS) - Decrease After load
Losartan (Cozaar),
Olmesartan (Benicar),
Valsartan (Diovan)
Common Uses: HTN and HF
PO/ 2 Hours
Intercations: MAOIs, alcohol, diuretics may increase hypotensive effects. ACE inhibitors and ASA may increase hyperkalemia and renal dysfunction
MoA: Prevent the release of aldosterone. They act on the renin-angiotensin system (RAS). ARBS block angiotensin II from the
angiotensin I receptors found in tissue. Potent vasodilator. Decreases peripheral resistance. Decrease the workload of the heart by decreasing afterload. This will increase cardiac output and keep blood moving forward out of the heart.
Advantages: Do not cause the constant, irritating dry
cough that ACE inhibitors do.
Disadvantages:Less effective for treating hypertension in
African-American clients.
Side Effects: Headache Dizziness Drowsiness GI complaints Fatigue
Adverse Effects: Orthostatic hypotension Hypoglycemia Hyperkalemia Renal dysfunction Angioedema
Interventions: Monitor BP and Heart rate, AST, ALT, BUN and creatinine.
Education: Rise slowly from lying and sitting position to standing position. Safety precautions. Can be taken on empty or full stomach. Do not use salt substitutes.

Eat foods high in potassium.
Pathophysiology of decrease Cardiac Output
Lack of proper perfusion.
Brain: Decreased LOC Heart: Increased Pain Lungs: Sound Wet and SOB Skin: Cool and Clammy Kidneys: UO goes DOWN Pulses: Decreased/ Thready
Arrthymias are no big deal until they affect CO
Pulseless V TACH, V FIB and A-systole
Coronary Artery Disease
Most common type of Cardiovascular disease. Includes Chronic stable angina and Acute Coronary Syndrome.
Chronic Stable Angina: Patho and treatment
Intermittent decreased blood flow to heart that leads to ischemia. This ischemia can lead to temporary pain/pressure in the chest because of the low perfusion due to exertion.
Relieved by Rest and nitro
Treatment:
Nitro
Beta blockers ( for prevention of Angina) - Decreases contractility, decreases CO thus decreasing workload of the heart.
Calcium Channel Blockers ( prevention of angina) - decreases the afterload through vasodilation and increases oxygen to the heart muscle
ASA: Antiplatelet.
Chronic Angina: Client Education and Teaching
Rest frequently Avoid Overeating Avoid excess caffeine of any drugs that increase HR Wait 2 hours after eating to excercise Dress warmly in cold weather ( any temperature extreme can precipitate an attack) Take Nitro prophylactically Smoking Cessation Lose Weight Avoid isometric exercise Reduce Stress
DO EVERYTHING YOU CAN TO DECREASE THE WORKLOAD OF THE HEART
Cardiac Catheterization: Pre and Post Procedure
Pre procedure:
Ask if allergic to Iodine/contrast or Shellfish
CHECK THAT KIDNEY FUNCTION because dye is excreted through the kidneys
Acetylcytsteine is given pre- procedure if client has kidney problems. It protects the kidneys .
HOT SHOT
Palpitations are normal
Post Procedure
Monitor Vital Signs
Watch the puncture site for bleeding and Hematoma formation
Assess Pulselessness, Pallor, Pain, Paresthesia and Paralysis, extremely distal from puncture site, as well as circulation and vascular check
Bed rest, Flat, Extremely straight for 4 -6 horus
Major complication is hemorrhage
report Pain ASAP
If the client is on metformin, you must hold this med for 48 hours post procedure. We are worried about blood sugar impacting the kidneys.
Acute Coronary Syndrome ( MI, Unstable Angina) : Patho and Signs and Symptoms
Decreased Blood flow to the myocardium leads to both iscehmia and necrosis
SIgns and Symptoms :
Pain that is crushing, with pressure radiating to left arm and left jaw, N/V or pain between the shoulder blades
Cold/clammy/ drop in BP and pulse
Cardiac Output drops
ECG changes
Vomiting ( stimulates the vagus nerve which lowers the heart rate)
PVC’s because of hypoxia in the heart
In women, they usually present with GI signs and symptoms, epigastric discomfort or pain between shoulders, an aching jaw or choking sensation.
In the elderly and Diabetic, there will be behavioural changes, less or no pain, fainting and SHORTNESS OF BREATH
CPK-MB
Cardiac specific isoenzyme
Increased with damage to cardiac cells
Elevates within 3 - 6 hours and peaks in 12 to 24 hours
Troponin
Cardiac Biomarker with high specificity to myocardial damage
Elevates within 3 to 4 hours and remains high for up to 3 weeks
Myoglobin
Increased within 1 hour and peaks in 12 hours. Negative results are a good thing
Major Arrhythmias
Pulseless V. Tach, V.Fib and Asystole put the client at risk for sudden death
Priority treatment V. Fib is DEFIB
If the first shock doesn’t work and the client remains in V-Fib, what is the first vasopressor we give? Epinephrine
Amiordarone is an anti-arrhythmic and is used when V.Fib and pulseless VT are resistant to treatment and also for fast arrhythmias ( not a vasopressor)
