Acute Biologic CrisisCondition that may result to patient
mortality if left unattended in a brief period of time.
Condition that warrants immediate attention for the reversal of disease process and prevention of further morbidity and mortality.
Conditions that can be considered ABCHeart failure & DysrhythmiasRespiratory Failures & Acute
Respiratory Distress SyndromeRenal Failure & End Stage Renal

Coronary Artery Disease & Acute Coronary SyndromesMost Common cause of
cardiovascular disability and death.It refers to a spectrum of illnesses
that range from the least life threatening to the most life threatening acute coronary syndrome(AMI/ Heart attack).
Coronary Artery Disease & Acute Coronary SyndromesIncomplete occlusion of the coronary
arteries lead to Angina (ischemia)Complete occlusion of the coronary
arteries lead to Myocardial InfarctionThe heart will pump harder to meet the
O2 demand leading to Congestive Heart Failure.

Cardiovascular AssessmentChest PainMost commonDue to Ischemia or MIPrecipitated by stress or can be relieved by
Nitroglycerin (NTG)In MI, it is more intense, unrelated to
activities and can’t be relieved by NTGIf it occurs during breathing, suspect
respiratory problems
Rough diagram of pain zones in myocardial infarction (dark red = most typical area, light red = other possible areas, view of the chest).
Cardiovascular AssessmentDyspneasubjective feeling (inability to get enough
air).Dyspnea on exertion is due to increased O2
myocardial demand.Orthopnea is related to blood pooling in the
pulmonary bed; suspect Pulmonary EdemaAny sudden or acute dyspnea may be a sign
of Pulmonary Embolism
Tightness of Chest
Cardiovascular AssessmentCough/sputumMucoid and foamy sputum can be a sign of
CHFPink-tinged frothy appearance may signal
Pulmonary Edema.Whitish, viral infectionChange in color other than the above
mentioned may signify bacterial infection.
Cardiovascular AssessmentCyanosisBluish discoloration of the skin and
mucous membraneSat O2 is below 90%
FatigueMay be due to Anemias or related to
decreased Cardiac Output
Cardiovascular AssessmentPalpitationsAwareness of rapid or irregular heart beatAutonomic Nervous System and Adrenal
Glands response (stress)
SyncopeTransient loss of consciousnessDue to decreased cerebral tissue perfusion
Cardiovascular AssessmentEdemaDue to: Increased Hydrostatic Pressure
(HP)Decreased Colloidal Oncotic
Pressure (COP)Obstructed Lymphatic or
Vascular System Related to Inflammatory reaction
Types of EdemaBilateral edema
= CHF or Renal FailureUnilateral edema
= Vascular or Lymphatic obstructionNon-pitting edema
= Inflammatory Pitting edema
= HP and COP derangement
Cardiovascular AssessmentSkinColor, temperature, hair growth,
nails, capillary refillspooning of fingers /clubbing of
fingers
Clubbing of Fingers
Cardiovascular AssessmentHeart rate – 60-100Rhythm – regular or irregularBruits and Thrills – murmurlike; vascular
in origin
- palpate a thrill, auscultate a bruitBlood PressureJugular venous pressure
Cardiovascular AssessmentCardiac rate and rhythmTachycardia = ↑ 100 beats/minuteBradycardia = ↓ 60 beats/minuteArrhythmias = irregular rate and
rhythm
Cardiovascular AssessmentS1 closure of AV valves (lub)S2 closure of SL valves (dub)S3 & S4 diastolic filling soundS3 heard after S2
if present suspect CHF; commonS4 is heard prior to S1; if present suspect
non-compliant ventricles although this is common among the elderly.
Cardiovascular AssessmentMurmurs- turbulence of blood flow; if positive
watch out for FVE; normal until 1 year oldPericardial Friction Rub -“squeaking sound”;
suspect pericardial effusion if this is heardMuffled Heart Sound - if positive rule out
Cardiac Tamponade and other similar problems like Effusion
Laboratory & Diagnostic TestComplete Blood Count- RBC suggest tissue
oxygenation.
Elevated WBC may indicate infectious heart disease and MI.
Erythrocyte Sedimentation Rate (ESR)- Its is elevated in infectious heart disorder or MI.
Normal range: Males: 15-20mm/hr
Females: 20-30 mm/hr
Laboratory & Diagnostic TestBlood Coagulation Test:
1.Prothrombin Time (PT, Pro Time)- It measures time required for clotting to occur. Used to evaluate effectiveness of COUMADIN. Normal range 11-16 secs.
2.Partial Thromboplastin Time (PTT)- Best screening test for disorders of coagulation. Used to determine the effectiveness of HEPARIN. Normal Range: 60-70 secs.
Laboratory & Diagnostic TestBlood Urea Nitrogen (BUN)- Indicator of
renal function
Normal Range: 10-20mg/dl (5-25mg/dl is also accepted).
Blood Lipids:
1.Serum Cholesterol: 150-200mg/dl
2.Serum Triglycerides: 140-200mg/dl.
Laboratory & Diagnostic TestSerum Enzymes Studies
1.Aspatate Aminotransferase(AST)- Elevated level indicates tissue necrosis. Normal Range: 7-40mu/ml
2.CK-MB- Elevated 4-6hrs from the onset of infarction; peaks 24-36 hrs. returns to normal 4-7 days.
Normal Range: males: 50-325mu/ml; Females: 50-250mu/ml
Laboratory & Diagnostic TestSerum Enzymes Studies
3. Lactic Dehydogenase (LDL)- Onset: 12hrs; Peak: 48hrs; returns to normal: 10-14 days
4. Hydroxybuterate Dehydroxynase (HBD)- it is valuable in detecting silent MI because it is elevated for a long period of time.
Onset: 10-12hrs; Peaks: 48-72hrs; Returns to Normal 12-13 days
Laboratory & Diagnostic TestSerum Enzymes Studies
5. Troponin- Most specific lab test to detect MI. Troponin has 3 compartments: I,C, &T .
Troponin I persist for 4-7 days.
Angina Myocardial Infarction
Chest Pain- tightness & heaviness
Severe crushing, stabbing chest pain
Relieved quickly:3-15min by rest or sublingual nitrogen.
Not relieve by rest and medication
Initiated by physical exertion or stress
Pain last longer >20min
Radiation may or may not be present
May or may not have radiation of pain
Frequently associated with shortness of breath
Laboratory & Diagnostic TestSerum Electrolytes/ Blood Chemistry:
1.Sodium (Na)
2.Potassium (K)
3.Calcium (Ca)
4.Magnessium (Mg)
5.Glucose
6.Glycosylated Hemoglobin (Hemoglobin A1c)
Laboratory & Diagnostic TestECG/ EKG- ST segment elevation and T
wave inversion

Goal:Pain reliefReduction of myocardial oxygen consumption
Prevention and treatment of complications
InterventionAdmit to the CCU/ ICUActivity
Day 1: bed rest, if stableDay 2-3: bed rest, but patient
may be allowed to sit on a chair for 15-20 minutesEarly mobilization is
recommended for uncomplicated AMI
InterventionMonitoring Vital Signs
First 6 hours- q30-60 minutesNext 24 hours- q 2 hoursThereafter q 4 hours
DietNPO: 1st 24 hoursIf stable low salt, low cholesterol
diet
InterventionIV Fluids
D5W to KVOIf unable to take food/fluid per orem1000ml/8 hours
K supplement
InterventionPain Medication
Morphine SO4 (2-5mg/IV dose)Potent analgesicPeripheral venous vasodilationPulmonary venous distentionInferior wall MI: may increase vagal
discharge
TranquilizresTo decrease anxietyDiazepam (5-10 mg per IV/orem)
LaxativeTo prevent straining during defecation
Lactulose (HS)
Drugs to Limit Infarct SizeBeta Blockers
Hyperdynamic states, HPN w/o evidence of heart failure
Reduce myocardial oxygen consumption by decreasing: BP. Heart Rate, Myocardial Contractility and calcium output.
Ex: Propranolol, Metoprolol, Atenolol
Nursing Consideration:
1.Assess Pulse Rate before administration; withhold if bradycardia is present.
2.Administer with food, may cause GI upset.
3.Do not administer with asthma it causes Bronchoconstriction.
4.Do not give to patient with DM, it causes hypoglycemia.
5.Antidote for Beta Blocker poisoning is Glucagon
NitratesAct by augmenting perfusion at the border
of ischemic zone.Generalized vasodilationReducing myocardial O2 demand
Lowering preloadLowering afterload
Ex: IV Nitroglycerine, Sublingual Niotroglycerine, Oral/Transdermal Nitroglycerine
Nursing Considerations:
1.Only a maximum of 3 doses at 5 min. interval.
2.Offer sips of water before giving it sublingually.
3.Store the medication in a cool, dry place; use dark /amber container.
4.If side effects is noticed do not discontinue the drug this is usual in the first few doses of medication.
5.Rotate skin sites for nitro patch.
ACE inhibitors reduce mortality rates after MI. Administer ACE inhibitors as soon as
possible ACE inhibitors have the greatest benefit in
patients with ventricular dysfunction. Continue ACE inhibitors indefinitely after
MI. Angiotensin-receptor blockers may be used
as an alternative adverse effects, such as a persistent cough,
Aspirin and/or antiplatelet therapy
Continue aspirin indefinitelyClopidogrel may be used as an alternative only if resistance or allergy to aspirin.
Nursing Considerations:
1.Assess for signs and symptoms of Bleeding.
2.Avoid straining at stool to avoid rectal bleeding.
3.It should be given with food.
4.Observe for toxicity- Tinnitus (ringing of ears).
5.May cause Bronchoconstriction- Observe for wheezing.
Heparin
1.Assess for S/S of Bleeding.
2.Keep Protamine Sulfate available.
3.If used SQ. do not aspirate to prevent hematoma formation.
4.Monitor for PTT or APTT
5.Used for a maximum of 2 weeks.
Coumadin (Warfarin Sodium)
1.Assess for bleeding
2.Keep Vitamin K available.
3.Monitor for Prothrombin Time
4.Do not give together with aspirin to prevent bleeding.
5.Minimize green leafy vegetables in the diet.
thombolytic therapyThe effectiveness:
highest in the first 2 hoursAfter 12 hours, the risk associated with thrombolytic
therapy outweighs any benefitcontraindicated
unstable angina and NSTEMIand for the treatment of individuals with evidence of
cardiogenic shockstreptokinase, urokinase, and alteplase (recombinant
tissue plasminogen activator, rtPA), reteplase, tenecteplase
Surgical CarePercutaneous Transluminal Coronary Angioplasty
-treatment of choice PCI provides greater coronary patency lower risk of bleedingand instant knowledge about the extent of the
underlying disease.A specially designed balloon – tipped catheter is
inserted uder flouroscopic guidance and advance to the site of the obstruction.
Intravascular StentingBiologic Stent is produced through
coagulation of collagen, ellastin and other tissues in the vessel wall by laser, photocoagulation or radio frequency.
It is done to prevent restenosis after Percutaneous Transluminal Coronary Angioplasty.
Emergent or urgent coronary artery graft bypass surgery (CABG) is indicatedangioplasty fails Severe narrowing of 1
or more coronary artery.
Commonly used: Saphenous vein and internal mamary artery.
ComplicationsInflammationMechanicalElectrical abnormalities
Cardiac RehabilitationA process which a person restored to
health and maintains optimal physiologic, psychosocial and recreational functions.
Begins with the moment a client is admitted to the hospital for emergency care, it continues for months and even years after the client is discharged from the health care facility.
Goals of Rehabilitation:
1.To live as full, vital and productive life as possible.
2.Remain within the limits of the hearth’s ability to respond to activity and stress.
Activities: Exercise may gradually implemented
from the hospital onwards. Exercise session is terminated if any
one of the following occurs: cyanosis, cold sweats, faintness, extreme fatigue, severe dyspnea, pallor, chest pain, PR more than 100/ min., dysrhythmias greater than 160/95mmHg.
Teaching and CounselingSelf management education guide.
Control hypertension with continued medical supervision.
DietWeight reduction programProgressive exerciseStress management techniquesResumption of sexual activity after 4-6 weeks
from discharge, if appropriate.
Teaching guide on resumption of sexual activities:
Assume less fatiguing position.The non- MI partner take the active roleTake nitroglycerine before sexual activityIf dyspnea, chest pain or palpitations
occur, moderation should be observed; if symptom persist stop sexual activity.
Develop other means of sexual expression.
